Company: Lianggu Valve Group Co., Ltd.

Product Description: [Product Applications]The electric flat gate valves produced by the group are sliding valves with parallel gate plates as closing parts. The closing parts can be single gate plates or double gate plates with a spreading mechanism between them. The pressing force of the gate plate against the valve seat is controlled by the medium pressure acting on the floating gate plate or floating valve seat. For double gate plate flat gate valves, the spreading mechanism between the two gate plates can supplement this pressing force.[Product Classification]Flat gate valves can be classified into manual flat gate valves, pneumatic flat gate valves and electric flat gate valves according to the driving mode. According to their purposes and application occasions, they can be divided into flat gate valves with diversion holes, flat gate valves without diversion holes, oilfield flat gate valves, pipeline flat gate valves, gas flat gate valves and so on.[Structural Features]This series of products adopts a new type of floating sealing structure, which is suitable for pipelines carrying oil products, natural gas and other media with a pressure not greater than 15.0MPa and a temperature ranging from -29 to 121℃, as a device for controlling the opening, closing and regulation of media. The product has novel structural design, proper material selection, strict testing and easy operation, with strong corrosion resistance, wear resistance and erosion resistance. It is an ideal new-type equipment in the petroleum industry.1. Adopts floating valve seats, supports two-way opening and closing, with reliable sealing and flexible opening and closing.2. All gate plates are precisely guided by guide strips, and hard alloy is sprayed and welded on the sealing surfaces to resist erosion.3. The valve body has high load-bearing capacity, and the passage is straight-through. When fully opened, it is贯通 with the diversion hole of the gate plate, similar to a straight pipe, with very small flow resistance. The valve stem adopts composite packing and multiple seals, which ensures reliable sealing and low friction.4. When closing the valve, turn the handwheel clockwise, and the gate plate moves down to the bottom. Under the action of medium pressure, the inlet end sealing seat is pushed toward the gate plate, forming a large sealing specific pressure, thus forming a primary seal. At the same time, the gate plate is pressed against the outlet end sealing seat, forming a double seal.5. Due to the adoption of double seals, vulnerable parts can be replaced without affecting the normal operation of the pipeline. This is an important feature that distinguishes our company's products from similar products at home and abroad.6. When opening the gate plate, rotate the handwheel counterclockwise, and the gate plate moves upward. The diversion hole is贯通 with the passage hole. With the rising of the gate plate, the through hole gradually enlarges. When reaching the limit position, the diversion hole coincides with the passage hole, and the valve is fully opened at this time.[Design Standards]Design and manufacturing standard: JB/T 5298Structure length standard: JB/T 5298Connecting flange standard: GB/T 9113Pressure and temperature rating: GB/T 12224-2005Test and inspection standards: GB/T 13927-2008, JB/T 5298 more>

Product Description: HHL Constant Force Cable Retracting Gate Opening Sensor (Version 13.0)User ManualXuzhou Haihe Hydrological Equipment Co., Ltd.Xuzhou Economic Development ZoneI. OverviewThe HHL Constant Force Cable Retracting Gate Opening Sensor features an internal steel cable that is extended and directly connected to the gate being measured. When the gate is raised or lowered, the steel cable drives a measuring wheel coaxial with the encoder, causing the encoder to rotate synchronously with the gate. This converts the gate's vertical movement into the rotation of the encoder shaft, outputting corresponding position information. Its internal mechanical structure mainly consists of a constant force spring, spring wheel, measuring wheel, wheel shaft, etc. During descent, the gate pulls the spring to reverse wind, driving the mechanical mechanism to rotate. During ascent, the force generated by the reverse-wound spring drives the mechanical mechanism to rotate and retract the steel cable. The sensor has a rational structure, is easy to install, has strong anti-interference capability, high resolution, large range, long service life, and integrates detection and A/D conversion. It also features signal tracking and memory function after power loss. It can be used for long-term detection of displacement of measured components while ensuring stable and reliable performance. It is suitable for measuring and controlling the lifting height of various gates (such as flat gates, radial gates, miter gates, gantry cranes, bridge cranes, etc.). It is an ideal sensor for displacement measurement and control in rivers, lakes, reservoirs, ship locks, hydropower stations, hydrological stations, water plants, and the petrochemical industry.II. Main Technical Specifications:1. Measuring Range: Standard 10 meters, customizable non-standard2. Resolution: 1 millimeter or 1 centimeter 3. Measurement System Error: ≤2cm4. Dimensions: Length 304mm x Width 152mm x Height 212mm5. Base Plate Mounting Holes: Length 275mm x Width 120mm, 4-M5x25 screws6. Output Signal (Optional): A-4-20mA; B-Parallel Gray Code; M-RS485; S-Serial SSI Signal7. Operating Voltage: DC12-24V8. Protection Rating: IP639. Environmental Parameters: Temperature -25℃ to +80℃, Relative Humidity ≤95% (RH40℃)III. Installation and Debugging Steps:1. Lower the gate to the lowest position.2. Install the constant force cable retracting gate position sensor upright or sideways in a suitable location. Attach the extending steel cable to the connection point between the hydraulic rod and the gate or directly to the gate (ensure the steel cable remains parallel to the hydraulic rod as much as possible). (Note: The extendable length of the steel cable should not exceed the design value. If the distance between the sensor and the cable attachment point is large, additional steel cable of corresponding length can be connected to the end to avoid breaking the internal cable.)3. Open the dust cover.4. Press and hold the reset button for more than 3 seconds. The upper display should now show 0.5. Raise the gate to any height.6. Compare the actual height of the gate with the displayed value. If inconsistent, check if the steel cable is parallel and if retraction is smooth, etc.7. After confirming accuracy, reinstall the dust cover. The installation and debugging are complete. more>

For low-risk packages, the system directly releases them; for packages requiring inspection, intelligent sorting directs them to designated channels, reducing manual intervention and increasing clearance speed by over 80%.3. Full Process Monitoring, Ensuring Package SecurityCross-border e-commerce packages may face risks such as loss or misdelivery during transportation. Smart gates are equipped with AI monitoring and IoT tracking technology, recording the entry and exit status of packages in real-time to ensure full traceability. If any abnormalities are detected, the system immediately issues alerts, effectively reducing the rate of lost items.4. Data-Driven Optimization of Logistics RoutesThe system collects real-time customs clearance data, analyzing package flow and clearance times to help businesses optimize logistics routes. For example, for cross-border e-commerce warehouses with high-frequency clearances, the system can intelligently allocate gate resources to reduce congestion and deliver packages to consumers faster.5. Diverse Payment Methods, Enhancing Settlement EfficiencyFor packages requiring tariff or logistics fees, smart gates support online payments, e-wallets, and QR code payments. Upon successful payment, packages are automatically released, avoiding delays from traditional cash or manual settlements and making cross-border logistics more convenient.Smart Gate Systems utilize technologies such as AI recognition, automated declaration, and intelligent monitoring to achieve "second-level clearance" for cross-border e-commerce packages, significantly shortening logistics time and enhancing consumer satisfaction. In the future, with continuous technological advancements, smart gates will become the "express lane" for cross-border logistics, helping businesses seize market opportunities. more>
