Subway Gate Retractable Wing Gate
$99999
Category: Others
Company:
Product Description: As the core equipment in subway stations for controlling passenger flow and ensuring orderly passage, subway flap gates integrate mechanical structure, intelligent recognition, and safety management technologies. Their functional design closely aligns with the operational requirements of "high flow, high safety, and high efficiency" in subways, which can be specifically categorized as follows:I. Core Passage Control FunctionsPrecise Identity Verification and ReleaseSupports multiple verification methods: Linked with the subway ticketing system, it can quickly verify passengers' ticketing or boarding permissions by swiping transportation cards (IC cards), scanning codes (QR code tickets, mobile app ride codes), or facial recognition (piloted in some cities).After permission is confirmed, the flaps (made of metal or acrylic) extend or retract rapidly within 0.5-1 second to open the passage. The passage automatically closes after passengers pass through, with a single channel capable of handling 30-40 people per minute, meeting the high-efficiency flow demands during peak hours.Direction Control and Anti-ReverseUses infrared sensors or radar to detect passenger movement direction, with the default setting as "one-way passage" (e.g., entry gates only allow entry, exit gates only allow exit). If reverse movement is detected (e.g.,强行闯入 from an exit gate), it immediately triggers audible and visual alarms while keeping the flaps closed to prevent fare evasion or chaos.II. Safety Protection FunctionsAnti-Pinch and Anti-Collision ProtectionMultiple sets of infrared sensors are installed on both sides of the gate and inside the passage to detect the presence of people, luggage, or other objects in real-time. If an obstacle is detected during flap closure, the system immediately stops and reverses the movement to avoid pinching passengers or damaging items (especially for those carrying large luggage, pushing strollers, or with mobility issues).Some high-end models feature "flexible anti-collision" design, where the flaps use elastic materials or buffer structures to reduce impact force even in minor collisions.Emergency ResponseUpon receiving emergency instructions from the station (e.g., fire,突发事件), the flap gates can be remotely controlled via the backend system to enter "constant open mode," where all flaps remain open to ensure rapid passenger evacuation.In case of gate malfunction (e.g., motor jamming, sensor failure), a self-check procedure is triggered, automatically switching to a safe state (e.g., flaps open or remain in place) to prevent channel blockage or passenger entrapment due to equipment failure.III. Operational Management Support FunctionsPassenger Flow Data Statistics and MonitoringBuilt-in counting sensors provide real-time statistics of the number of people entering and exiting each gate channel. Data is uploaded to the station management system, helping staff understand passenger flow distribution and adjust the number of open gates promptly (e.g., opening all channels during peak hours).Some gates are equipped with integrated cameras that link with the monitoring system to record abnormal passage behaviors (e.g., climbing over,强行冲撞), providing evidence for subsequent management and investigations.Self-Diagnosis and AlertsFeatures intelligent diagnostics to automatically check the operational status of components such as motors, sensors, and circuits. If a malfunction is detected (e.g., flap jamming, communication interruption), alerts are displayed on screens or indicator lights (e.g., "Equipment malfunction, please detour"), while alarm information is sent to the backend for quick maintenance response, minimizing impact on passage.Ticketing Integration and Exception HandlingReal-time communication with the subway ticketing system ensures that if issues arise (e.g., "insufficient card balance," "invalid QR code," "mismatched entry/exit information"), the gate denies passage and displays corresponding prompts (e.g., "Please recharge," "Please pay excess fare"), directing passengers to the service counter for resolution, thereby ensuring accurate ticketing management. more>

Electric gate valve, electric knife gate valve, slab gate valve, flat gate valve, electric control valve DN800, customizable.
$888
Category: Machinery & Equipment/Valves/Gate Valves
Company: Yangzhou Ruiwen Valve Equipment Technology Co., Ltd.
Product Description: Electric Gate Valve Keywords: Electric gate valve, electric knife gate valve, plate valve, flat gate valve, electric control valve Models: DN150, DN200, DN300, DN400, DN500, DN600, DN800 (customizable for non-standard sizes) Introduction: The electric gate valve is a type of plate valve. This electric control valve uses various types of internal materials, expanding its application range. The use of sulfur-resistant materials and special surface treatment processes enables the valve to be used in environments containing sulfur media. Structural Features of the Electric Gate Valve: ① The valve adopts a pressure self-tightening seal or a valve body and bonnet gasket sealing structure, ensuring safe and reliable operation. ② The valve disc uses a double gate plate with a universal top structure in the middle, which automatically adjusts the fit between the disc and the seat sealing surface, ensuring the valve's sealing. This structure also facilitates maintenance, reduces costs, and offers good disc interchangeability. ③ The sealing surfaces of the disc and seat are plasma spray welded with cobalt-chromium-tungsten hard alloy, providing high hardness, wear resistance, anti-scratch properties, and a long service life. ④ The valve stem is made of nitrided steel with a nitrided surface, offering high hardness, anti-scratch properties, corrosion resistance, and a long service life. ⑤ The electric actuator is equipped with a torque control mechanism, on-site operation mechanism, and manual-electric switching mechanism. In addition to local operation, it supports remote operation, PLC control, and 4~20mA current input/output intelligent control. ⑥ Manual valves are opened by a manual mechanism or impact handwheel, reducing the operating force required. ⑦ The valve can be installed at any position in the pipeline. Carbon steel or alloy steel valves can be selected based on the medium and its temperature. ⑧ During initial installation and debugging, the valve must be manually opened to about half its position to avoid damage to the valve or electric actuator due to incorrect motor phase sequence. Structural Introduction Linear Electric Gate Valve: Simply put, it uses an electric actuator to control the valve, enabling opening and closing. It can be divided into two parts: the upper part is the electric actuator, and the lower part is the valve. Operating Principle of the Electric Gate Valve: The electric valve is typically formed by connecting an electric actuator to the valve, which becomes an electric gate valve after installation and debugging. The electric gate valve uses electrical energy as power to activate the electric actuator, driving the valve to perform opening, closing, and regulating actions, thereby controlling or regulating the pipeline medium. Applications of the Electric Gate Valve: Used for analog regulation of fluid, gas, and air system pipeline media flow, employing AI control. In large valve and air system controls, electric valves can also be used for two-position on/off control. Applications in petroleum and power industries can incorporate AI feedback signals, controlled by DO or AO, commonly seen in large pipelines and air valves. Features 1. Compact structure, rational design, high valve rigidity, smooth flow path, and low flow resistance coefficient. 2. Sealing surfaces made of stainless steel and hard alloy ensure a long service life. 3. Flexible graphite packing plate provides reliable sealing and easy, flexible operation. 4. Drive methods include manual, electric, pneumatic, and gear transmission. Structural forms include elastic wedge single valve, rigid wedge single gate plate, and double gate plate types. 5. Widely used in petroleum, chemical, and thermal power plants for connecting or cutting off media in oil, water, and steam pipelines as an opening and closing device. 6. Gate valves require relatively low force for opening and closing. 7. Gate valves allow unrestricted media flow direction, without causing flow disturbance or pressure reduction. Structural Classification Gate valves generally consist of a valve stem, valve body, bonnet, gate plate, driving device, and other components (fasteners, stem nut, sealing packing). Place the welding wire or welding rod on the pipeline socket inside the valve. Move the flame away when the welding rod or wire enters the joint. Move the flame back and forth as the alloy flows into the joint. At the appropriate temperature, the alloy will flow quickly and easily into the space between the pipeline shell and the valve sleeve. Once the joint is filled, the edge of the welding alloy will be visible. When the solder is in a viscous state, use a brush to remove excess solder. After the solder cools, wrap a gasket around the valve port. more>

Product Description: Manual flat gate valve for rainwater wells, soft-sealed square gate valve, 1. Before installing the slide gate valve, inspect the valve cavity and sealing surfaces to ensure no dirt or sand particles are attached;2. Bolts at all connection points must be tightened evenly;3. Check the packing area to ensure it is tightly compressed, guaranteeing both the sealing of the packing and the flexible opening of the gate;4. Before installation, users must verify the valve model, connection dimensions, and pay attention to the flow direction of the medium to ensure compatibility with valve requirements;5. When installing the valve, users must reserve necessary space for valve actuation;6. Wiring of the actuation device must follow the circuit diagram;7. The slide gate valve requires regular maintenance and should not be arbitrarily impacted or squeezed to avoid compromising the seal.Precautions and characteristics of electric slide gate valves: The opening and closing component of a slide gate valve is the gate, which moves perpendicular to the fluid flow direction. Slide gate valves can only be fully open or fully closed and cannot be used for regulation or throttling. The gate has two sealing surfaces, with the most common type being the wedge gate valve, where the two sealing surfaces form a wedge shape. The wedge angle varies depending on valve parameters, typically 50 degrees. The gate of a wedge slide gate valve can be made as a single piece, known as a rigid gate, or designed to allow slight deformation to improve manufacturability and compensate for deviations in the sealing surface angle during processing—this is called an elastic gate. When the slide gate valve is closed, the sealing can rely solely on medium pressure, meaning the medium pressure presses the gate's sealing surface against the opposite seat to ensure a seal, which is self-sealing. Most slide gate valves use forced sealing, requiring external force to press the gate against the seat when closed to ensure sealing. Slide gate valve sealing structures can be classified as soft seal or hard seal.Manual flat gate valve for rainwater wells, soft-sealed square gate valve. more>

Full-height turnstile access gate
$99999
Category: Others
Company:
Product Description: Full-height turnstile access control gates are constructed with 304 stainless steel for long-lasting durability. The core mechanism employs a DC brushless motor and a high-precision encoder, ensuring fast, accurate, and smooth rotation of the gate arm with quiet operation, low power consumption, and energy efficiency.Full-height turnstile mechanical anti-tailgating: Absolute one-person-one-gate control.Traditional turnstiles often suffer from tailgating vulnerabilities leading to major security incidents, but the mechanical anti-tailgating design of full-height turnstiles has completely rewritten the rules. With an adjustable rotation angle of 120° or 90°, the narrow passage creates a natural physical barrier, enforcing "single-person passage per cycle." In settings such as visitation rooms, even if someone attempts to closely follow the person ahead, the precise angle control of the gate arm will trap their shoulders outside the passage. This absolute control, derived from mechanical structure, is far more difficult to deceive than electronic detection.Dynamic locking structure: The end of climbing over or crawling under.The 3-meter-high stainless steel barrier is not just for show—the dynamic locking structure leaves climbers with no foothold. When sensors detect abnormal impact, the turnstile can activate emergency locking within 0.3 seconds, forming an impenetrable steel cage. More critically, its power-off self-locking design—used in models deployed at nuclear power plants—ensures that even during sudden power outages, the mechanical device maintains security, filling potential protection gaps present in half-height turnstiles.503Y full-height turnstile anti-reverse passage: The final piece for unmanned operation.The reverse prevention module is a technological marvel. When someone attempts to push the gate arm in reverse, the built-in hydraulic damper triggers mechanical locking with enough force to withstand the full impact of an adult male. Combined with a twenty-channel signal interface, the turnstile can deeply integrate with fingerprint recognition systems. Field tests at a certain base showed that this design reduced human-error-related security incidents by 92%, truly achieving impartial automated control.Synergistic effect of triple protection: A closed loop from technology to scenario.Mechanical anti-tailgating, dynamic locking, and anti-reverse passage are not merely additive but form a multi-layered defense network. In chemical plant acid tank areas, the triple protection addresses various risks such as employees bringing unauthorized personnel, outsiders climbing over, and internal materials being improperly removed. As security experts note: "What flows between the steel pillars of a full-height turnstile is not air, but a precisely calculated defense algorithm."Beyond turnstiles: The gateway to smart security ecosystems.When full-height rotating turnstiles integrate facial recognition and metal detection, they evolve into the central nervous system of intelligent security. Their modular design allows them to blend into the modern aesthetic of government buildings while matching solemn atmospheres. From access control to data analysis, this steel防线 is redefining the defensive dimensions of high-security venues.What guards safety is never cold steel alone, but the crystallization of human wisdom forged through technology. As the turnstile arm sweeps a perfect 120° arc, it delineates not only a physical boundary but also the highest respect for life and order. more>

Connections between the sensor and external components should avoid rigid coupling; instead, use couplings, connecting gears, or synchronous belts for transmission.3. During installation, pay attention to the allowable axial load and do not exceed the ultimate load.4. Ensure that the encoder's maximum speed is not exceeded. Exceeding the limit may cause loss of electrical signals.5. Wiring must be correct. Incorrect wiring may damage the internal circuit of the sensor.6. Do not bundle the sensor's output wires with power lines or transmit them through the same conduit. Avoid using them near wiring panels.V. Installation Methods for Gate Opening Sensors (Images Use Contact Encoders as Examples):Preface: Before installing the gate opening sensor, first determine the installation position. Only after confirming the position can the appropriate connection method be selected.(I) Installation Methods for Gate Opening Sensors with Hoist Winches (Recommended Methods 1, 2, and 3): The sensor's extension shaft connects to relevant gate components via elastic couplings, eccentric couplings, ratio gears, sprocket chains, or hoisting methods (measuring wheels, counterweights, measuring ropes).1. Elastic Coupling Installation: The sensor's extension shaft connects directly to the winch shaft or pinion shaft via a coupling.① Drill three M5 holes, 20mm deep, on the installation shaft of the winch. Fix the flanged shaft to the installation shaft.② Install a horizontal mounting plate at an appropriate position below the installation shaft, following the dimensions of the sensor bracket mounting holes.③ Secure the sensor bracket to the mounting plate. Ensure the sensor's extension shaft and installation shaft are as coaxial as possible. If the height or misalignment is too large, use shims under the bracket for adjustment. Then tighten the four mounting anchor screws (M6 screws).④ Attach the elastic coupling to the sensor's extension shaft and the connecting flange, and tighten.2. Eccentric Coupling Installation: The sensor's extension shaft connects directly to the winch shaft or pinion shaft via an eccentric coupling.① Drill three M5 holes, 20mm deep, on the installation shaft of the winch. Fix the eccentric flange to the installation shaft. Ensure the center hole of the eccentric flange is as concentric as possible with the installation shaft.② Install a horizontal mounting plate at an appropriate position below the installation shaft, following the dimensions of the sensor bracket mounting holes.③ Secure the sensor bracket to the mounting plate. Ensure the sensor's extension shaft and installation shaft are as coaxial as possible. If the height or misalignment is too large, use shims under the bracket for adjustment. Then tighten the four mounting anchor screws (M8 screws).④ Slide the other end of the eccentric coupling onto the sensor's extension shaft and tighten the fastening screw on the sensor's extension shaft end.3. Gear Connection Method: The sensor's extension shaft connects directly to the winch shaft or pinion shaft via gears.① Drill three M5 holes, 20mm deep, on the installation shaft of the winch. Fix the flanged shaft to the installation shaft.② Install a horizontal mounting plate at an appropriate position below the installation shaft, following the dimensions of the sensor bracket mounting holes.③ Slide gears onto the sensor's extension shaft and the flange adapter, and tighten the screws to ensure proper meshing. Then secure the sensor bracket to the mounting plate and tighten the M6 screws.Note: This connection method allows convenient installation and adjustment, with a wide range of height adjustments. It also enables scaling up or down the number of sensor rotations as needed.4. Sprocket Chain Installation: This method uses chain transmission to drive the sensor shaft, mainly for locations with limited installation space. First, install one sprocket on the winch shaft or pinion shaft, and another on the sensor's extension shaft. Then fit the chain. Choose the sensor's installation position based on the chain length, ensuring the chain has some free sag. Over-tightening may damage the sensor's extension shaft. Keep the sprockets parallel to prevent chain derailment.5. Hoisting (Measuring Rope, Measuring Wheel, Counterweight) Installation: Install a mounting plate with a thickness of at least 4mm at an appropriate position above the gate (e.g., flat gate, radial gate). Ensure the mounting plate is level. Process four M8 fixed screw holes and two Ф22 measuring rope holes on the plate. Note: The positions of the four M5 screw holes must ensure that the center plane of the sensor measuring wheel's groove and the measuring rope's motion trajectory during full travel are in the same vertical plane. Then fix the sensor bracket to the mounting plate and install the measuring wheel on the sensor's extension shaft. Attach one end of the measuring rope to a suitable position on the gate, and the other end, after passing through the measuring wheel's groove, to the counterweight. Note: The rope length should ensure that when the gate is closed, the length on the counterweight side is about 0.5m. If the rope and measuring wheel are not in the same vertical plane, loosen the measuring wheel's fastening screw and axially adjust its position on the sensor's extension shaft to prevent derailment during measurement.(II) Installation Methods for Gate Opening Sensors with Screw Lifts:1. Gear Installation Method: The sensor's output shaft connects directly to the screw lift's thread via a gear (the gear's addendum distance equals the screw lift's pitch). Install a mounting plate with a thickness of at least 4mm at an appropriate position on the screw lift, ensuring it is level.2. Fix the encoder to the mounting bracket and install the gear on the encoder's extension shaft.3. Secure the sensor bracket to the mounting plate. Ensure the gear meshes properly with the screw lift before finalizing the bracket installation. Once installed, the screw's upward and downward movement will drive the gear rotation, and the connected encoder will measure the gate's actual rise or fall position. more>
