Product Description: The lift-tilting flat steel gate is a hydraulic structure that combines the advantages of vertical lift and tilting gates, primarily used in projects such as hydropower stations and ship locks. Its features include:Structural CharacteristicsDuring operation, the gate leaf first lifts vertically for a certain distance, then rotates downstream while rising, eventually lying flat on top of the pier. This structure not only reduces the height of the operating platform, facilitating construction and lowering investment, but also enhances seismic resistance.Application ScenariosHydropower Stations: This type of gate has been put into use in projects like the Botang Hydropower Station and Zhangjiagou Gate Station, particularly offering advantages in projects with higher check flood levels.Ship Locks: Suitable for small and medium-sized ship locks, it addresses the issue of traditional miter gates being unable to withstand bidirectional water heads.Technical AdvantagesCompared to radial gates, the lift-tilting flat steel gate offers shorter piers, simpler structure, and smaller project scale; compared to vertical lift gates, it reduces the requirements for hoisting equipment.Maintenance PointsDaily maintenance and replacement procedures for wire ropes must be emphasized to ensure the safety and reliability of the hoisting system. more>

Product Description: Square spiral gate electric regulating valve for dust removal, square and round drain valves, civil air defense gate valves, electric slide gate valves: Precautions during use and their characteristics: The opening and closing component of a slide gate valve is the gate plate, whose movement direction is perpendicular to the fluid flow. Slide gate valves can only be fully opened or fully closed and cannot be used for regulation or throttling. The gate plate has two sealing surfaces, and the most common type of gate valve features two sealing surfaces forming a wedge shape, with the wedge angle varying depending on valve parameters, typically 50 degrees. The gate plate of a wedge-type slide gate valve can be made as a single unit, known as a rigid gate plate, or it can be designed to allow slight deformation to improve manufacturability and compensate for deviations in the sealing surface angle during processing; this type is called a flexible gate plate. When the slide gate valve closes, the sealing surfaces can rely solely on medium pressure for sealing, meaning the medium pressure presses the gate plate's sealing surface against the opposite valve seat to ensure a tight seal, which is known as self-sealing. Most slide gate valves use forced sealing, meaning that when the valve closes, external force is required to press the gate plate firmly against the valve seat to ensure the sealing surface's integrity. Slide gate valve sealing structures can be divided into soft sealing and hard sealing types.The three-way diverter valve is an ideal device for controlling rapid directional changes of materials in conveying systems, widely used in industries such as building materials, metallurgy, mining, light industry, and food for handling solid particles and powdered materials. The three-way diverter valve is constructed from high-quality steel plate welding, offering compact size, light weight, and low resistance. It is driven by an electric actuator (electro-hydraulic or pneumatic actuator), enabling quick switching of material flow direction. This valve mainly consists of the valve body, valve shaft, valve plate, crank mechanism, and electric actuator (electro-hydraulic actuator or manual mechanism). During operation, the linear reciprocating motion of the electric or hydraulic actuator (or manual external force) drives the valve shaft and valve plate through the crank to swing at a certain angle, thereby controlling material flow direction and diverting materials as needed.Square spiral gate electric regulating valve for dust removal, square and round drain valves, civil air defense gate valves. more>

Product Description: The application of ferromagnetic detection systems is highly focused on the core capability of "identifying ferromagnetic substances." Variations in needs across different fields further subdivide their functions, which can be primarily categorized as follows:1. Medical Field: Ensuring Safety of Magnetic Resonance Imaging (MRI) Equipment and PatientsDuring operation, MRI equipment generates a strong magnetic field. If ferromagnetic substances (such as metal dentures, keys, wheelchairs, etc.) enter the scanning room, they may be forcefully attracted by the magnetic field and collide with the equipment at high speed, causing "projectile injuries." Additionally, patients with ferromagnetic implants may experience displacement or heating of the implants due to the magnetic field, posing life-threatening risks.The core applications of ferromagnetic detection systems in this context include:Entrance Pre-Screening: Installing detection gates or detectors at the entrance of MRI rooms to mandatorily screen individuals for ferromagnetic items (such as mobile phones, coins, belt buckles, metal accessories, etc.). Audible and visual alarms are triggered to prevent hazardous items from entering.Patient Screening: Assisting medical staff in confirming whether patients have undeclared ferromagnetic implants (such as early metal contraceptive devices or residual surgical metal clips) to avoid risks during MRI scans.Equipment Protection: Preventing ferromagnetic tools (such as wrenches, screwdrivers) from accidentally entering the magnetic field area, thereby avoiding magnetization or damage to internal components and ensuring the normal operation of MRI equipment. more>

Product Description: Zigong Valve Z41F or Z43F Carbon Steel or Stainless Steel Soft Seal American Standard API6D Flat Gate ValveBefore inquiring or purchasing, users are requested to provide accurate parameters such as diameter, pressure, connection method, operation method, and main material. The above prices are reference prices, and prices vary for different models. Additionally, this product is custom-made with a production cycle, and delivery times also vary. Therefore, for specific model prices and delivery times, please call for consultation.API6D The flat gate valve is a sliding valve with a closure element in the form of a parallel gate. The closure element can be a single gate or a double gate with a spreading mechanism between them. The pressing force of the gate against the valve seat is controlled by the medium pressure acting on the floating gate or floating valve seat. In the case of a double gate flat gate valve, the spreading mechanism between the two gates can supplement this pressing force.API6D Flat gate valves can be divided into manual flat gate valves, pneumatic flat gate valves, and electric flat gate valves based on the driving method. According to their use and application, they can be categorized into flat gate valves with diversion holes, flat gate valves without diversion holes, oil field flat gate valves, pipeline flat gate valves, and gas flat gate valves, among others.API6D Flat gate valves are suitable for natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines, and other transmission pipelines, venting systems, and gas storage devices, serving as opening and closing equipment. Z43 type single gate flat gate valves with diversion holes are suitable for long-distance pipelines in natural gas extraction and purification.API6D Flat gate valve diameter range : DN25~1200 Pressure range: 0.6MPa~45MPa 150Lb~3000Lb Flat gate valves with diversion holes are used in pipelines that require pigging for cleaning, while those without diversion holes are used in pipelines that do not require pigging.API6D Flat gate valve advantages: Low flow resistance, with non-reduced ports having flow resistance similar to that of short pipes. Flat gate valves with diversion holes installed in pipelines can also be directly cleaned using pigs. Since the gate slides on two valve seat surfaces, flat gate valves are also suitable for media with suspended particles. The sealing surface of the flat gate valve is actually self-aligning. The valve seat sealing surface is not damaged by thermal deformation of the valve body. Moreover, even if the valve is closed in a cold state, thermal elongation of the valve stem will not overload the sealing surface.Supplier: Zigong ZIPU Ball Valve Pump Co., Ltd.

Gate valves have low fluid resistance, and the sealing surface is less subjected to冲刷 and erosion by the medium. 2. Gate valves are relatively easy to open and close. 3. The flow direction of the medium in gate valves is not restricted, causing no turbulence or pressure drop. 4. Gate valves have a simple shape, short structural length, good manufacturability, and wide applicability. The disadvantages of gate valves are as follows: 1. The sealing surfaces of gate valves are prone to erosion and wear, making maintenance relatively difficult. 2. Gate valves have large external dimensions, require certain space for opening, and have long opening and closing times. more>

Product Description: Pig Farm Vehicle Simple Disinfection Gate Washing and Disinfection Center Vehicle Entrance and Exit Epidemic Prevention Cleaning Drying Cleaning Center Breeding Farm Central Pipeline Network High-Pressure Cleaning MachineGood management is the prerequisite for ensuring biosafety in the washing and disinfection center. Only by effectively managing the washing and disinfection center can vehicles be properly cleaned, disinfected, and dried, ensuring they are not recontaminated. The management of the washing and disinfection center includes four parts: personnel management, vehicle management, material management, and on-site standardized management.Pig Farm Vehicle Simple Disinfection Gate Washing and Disinfection Center Vehicle Entrance and Exit Epidemic Prevention Cleaning Drying Cleaning Center Breeding Farm Central Pipeline Network High-Pressure Cleaning Machine1. Personnel Management. The washing and disinfection center should have dedicated personnel in charge, with the position designated as the center director, responsible for all matters in the center and serving as the primary inspector for vehicle cleaning, disinfection, and drying. All personnel must follow the unidirectional flow principle, moving from the gray zone to the clean zone in the sequence of "clothing and shoe disinfection → personnel shower → change of clothing and shoes → clean zone dormitory," ensuring that those entering the clean zone meet biosafety requirements.2. Vehicle Management. All private vehicles must be parked in the dirty zone parking lot and are strictly prohibited from entering the gray or clean zones. Livestock transport vehicles must strictly adhere to the unidirectional flow principle, entering through the dirty zone gate, undergoing thorough cleaning and disinfection in the washing area, draining and air-drying in the gray zone until no water remains inside or outside the vehicle, then proceeding to the drying room, and finally parking in the clean zone parking area after drying.3. Material Management. All materials entering the washing and disinfection center must enter through the gray zone door of the material room, undergo fumigation disinfection for over 24 hours, and be retrieved from the clean zone door. The entire搬运 process must ensure that only one door is opened at a time.4. On-site Standardized Management. The washing and disinfection center must be strictly divided into dirty, gray, and clean zones. Detailed on-site standardized management systems should be established based on the specific conditions of each center and biosafety requirements, strictly implemented, and regularly inspected and reviewed by designated personnel.Pig Farm Vehicle Simple Disinfection Gate Washing and Disinfection Center Vehicle Entrance and Exit Epidemic Prevention Cleaning Drying Cleaning Center Breeding Farm Central Pipeline Network High-Pressure Cleaning MachineEstablishing an integrated washing and disinfection center outside the pig farm serves two purposes: firstly, the vehicle washing and disinfection center can quickly, conveniently, and effectively create a specific "high-temperature + dry + clean" environment where most pathogenic microorganisms rapidly become inactive; secondly, it helps build multiple layers of biosafety protection circles from the outside to the inside centered around the pig farm, gradually reducing the environmental pathogen load from the exterior to the production area inside the farm. Therefore, setting up a vehicle washing and disinfection center is crucial to improve the "transportation safety factor" of the pig farm, ensuring that all external vehicles undergo thorough cleaning, disinfection, and drying to eliminate African swine fever virus and other pathogens before they enter the farm gates.The establishment of a washing and disinfection center on a breeding farm is intended to clean, disinfect, and dry vehicles entering the pig farm, as well as to clean and disinfect accompanying personnel and items, quickly and efficiently eliminating most pathogens. However, the management of the washing and disinfection center is the true guarantee of its safety and prevention effectiveness. Only by following standardized and regulated disinfection procedures and conducting strict post-disinfection inspections can a multi-layered biosafety protection circle be formed, with the pig farm at its core and the washing and disinfection center as a barrier, effectively ensuring the safety of the pig farm. more>
