Flat gate valve gate the latest technology products reach the world's leading standard

In today's world the highest technical level and filled the domestic blank of high sulfur acid resistant special flat gate valve gate - CL150LB, high-pressure CL900 - 2500LB- DN25 - 500 flat gate valve gate, has successfully developed. Flat gate valve is a kind of closed a door for the parallel slide valve of the gate. Close it a can be a single ram or a meantime double ram with open institution. Ram to clamping force is by the effect of the valve seat and floating gate or floating medium pressure to control the valve seat. If it is double ram plate gate door see two gate open institution can supplement the clamping force. Flat gate valve gate features: 1, fully closed structure, good protective performance, can meet the requirements for all-weather 2, flat gate valve door is closed automatically removing the inner cavity and pressure, ensure the safety of using 3, when fully open, smooth channels for straight line, small flow resistance coefficient, no pressure loss, can connect the bulb cleaning line 4, the valve seat O ring seals and exert pre-tightening force of floating valve seat structure, make the seal of flat gate valve door import and export; And the structure of the open-close torque is only 1/2 of ordinary valve door, can be achieved easily open and close the valve gate 5, USES the packing structure with the sealing ability, without constant adjustment, features very light open and close, and the sealing is reliable, an auxiliary sealing grease injection structure is set in the packing, the sealing performance absolutely reliable and truly achieve zero leakage; Solve the door packing place of universal valves to be easiest leak outward ills in today's world the highest technical level and filled the domestic blank of high sulfur acid resistant special flat gate valve gate - CL150LB, high-pressure CL900 - 2500LB- DN25 - 500 flat gate valve gate, has successfully developed. At present, the product has been successfully used in puguang gas field of sinopec main body development of surface gathering projects in the yard. It is understood that the product has a small flow resistance, flow and can connect the function of the sweeper, and has the advantages of opening and closing and lighter, can be widely used in the extraction of oil and gas and sulfur gathering, oil and gas pipeline, oil refineries and other conditions, as a lifting device to control the medium circulation and globe. According to the needs of engineering, the gate valve with manual, bevel gear drive, such as explosion-proof electric drive way. The valve door design also has a valve position switch instructions, the valve lever shielding, prevent wrong operation protection lock, etc. , to ensure the safe operation of the valve door, and avoid the wrong operation. It adopts single ram hard seal, floating patent technology of valve seat, ensure that stuff won't go to the valve seat back, have fireproof and anti-static function, the blank casting valve door smelting and casting for the company. Special structure of patent elastic fire valve seat, overcome the limitations of the past can only use O rubber ring, and the application of the flat gate valve gate of elasticity of the valve seat area expanded to high temperature and high pressure field. Concerned expert thinks, to promote the success of the valve gate and application of efficient machinery and oil industry in our province economic and technological, played a key role in the home also has a large influence, have wide prospect of application in the market.
