Q347H worm gear fixed pneumatic valve ( Dynamic figure) _ pneumatic components factory valve industry

Pneumatic pneumatic valve description of worm gear fixed pneumatic valve: Q347H worm gear fixed pneumatic valve is according to API 6 d, GB/T12237 design production of pneumatic valves, the pneumatic valve is suitable for Class150 ~ Class2500, PN10 ~ PN420 various piping. Worm gear fixed pneumatic valve features: 1, the fluid resistance is small, the resistance coefficient with the length of the pipe is equal, when fully open ventilation cleaning pipe fittings. 2, have fire prevention, anti-static, stem launch function, such as simple structure, small volume as a whole. 3, reliable seal, soft seal pneumatic valve sealing surface material widely used ptfe, hard seal pneumatic valve adopts spray welding tungsten carbide carbide, sealed performance is in the pipeline of oil, natural gas medium is widely used in the system. 4, convenient operation, opening and closing rapidly, from open to close just rotate 90 °, is advantageous for the remote control. 5, convenient maintenance, pneumatic valve structure simple, the seat ring is active, disassembly is convenient. 6, in the full open or full close, aerodynamic body and seat sealing surface and the dielectric isolation, medium by pneumatic valve sealing surface does not cause erosion. 7, worm gear fixed pneumatic valve body according to the need for forged steel or cast molding structure. 8, fixed pneumatic valve compared with the floating type pneumatic valve structure is complex, generally suitable for the occasion of large diameter and high pressure, fixed most of pneumatic valve designed before the valve seal, so the body bottom outlet, in order to check the leakage of sealing surface differ in testing the pressure. Worm gear fixed fire protection design of pneumatic valve: there is a fire at the scene of the worm gear fixed on the use of pneumatic valve, non-metallic materials, such as when ptfe seat seal, valve stem seal, valve stem packing and flange sealing gasket under the high temperature decomposition or destruction, worm gear fixed pneumatic valve can use specially designed metal to metal auxiliary sealing structure, effectively control pneumatic valve leakage and the leakage. Pneumatic valve with fire protection requirements for the users, my company's fire protection design of API607 standard specification requirements. Worm gear fixed pneumatic valve anti-static structure: according to user requirements, worm gear type pneumatic valve can be equipped with anti-static structure. Applying a plunger type electrostatic spring device, pneumatic between body and body form directly electrostatic channels or through stem form static channel between the pneumatic body and the body. Then pneumatic body and seat switch friction produces in the process of static electricity through the body to the earth, and to prevent electrostatic spark may cause fire or explosion danger. Pneumatic components factory specializing in the production of valve industry Q347H worm gear fixed pneumatic valve manufacturers, have fire prevention, anti-static, introduced the advantages of stem, deeply the general customers trust and support. Customers can according to Q347H worm gear fixed pneumatic valve ( Dynamic figure) Selection and reference, if the worm gear fixed pneumatic valve need to configure the electric valve actuators, is equipped with electric explosion-proof device, or a pneumatic valve actuator, pneumatic valve is equipped with triple pieces, and worm gear fixed pneumatic valve body materials, the use of related technologies, such as temperature, nominal pressure, nominal size parameters, so that our sales staff for selection and quotation. : Q647F/H pneumatic fixed pneumatic valve Q947H/F electric fixed pneumatic valve Q347H worm gear fixed pneumatic valve ( Dynamic figure) Fixed working principle of the pneumatic valve American standard Dynamic figure) Electric top mounted fixed working principle of the pneumatic valve ( Dynamic figure) Stationary and working principle of the pneumatic valve structure
