Shanghai flat plate gate valve import standard flat plate gate valve
)
Profile: flat gate valve 1, considerable internal pressure valve when the gate is closed, the valve seat surface, the formation of the initial PTFE seal rings, each valve open or closed, the valve seat ring to clean the two gate Side
2, management of pressure exerted on the valve, the pressure acting on the gate, forcing it to close on the export of PTFE seat ring, compress it until it stopped at the steel gate valve seat, so that to form a double seal, first PTFE to metal seal, and then metal to metal seal firmly seat was picked up groove, at this point, O-ring to prevent any back of the media stream. 3, after the pressure relief valve, metal seal, pipe pressure on the import of the valve seat, towards the gate so that it gets into the PTFE to metal seal, and, O-ring groove and form a tight seat Seal
4, excess pressure relief valve automatically when the valve pressure is greater than the pipeline pressure, due to thermal expansion, import seat into the groove, the valve body of excess pressure in the valve seat and gate leakage into the pipe between the .
1, valve seat with O-ring seal and the preload of the floating seat structure, import and export of two-way valve to seal plate; and that the structure of the normal valve opening and closing torque is only 1 / 2, can be achieved easily opening and closing the valve
2, in full, the channel smooth straight line, flow resistance coefficient is extremely small, no pressure loss, can pass the ball clean wool pipeline
3, with self sealing ability of filling the structure, without frequent adjustment, open and close very lightweight, and reliable seal, stuffing seal oil into the structure with, absolutely reliable sealing performance, thereby achieving zero leakage; solve a common valve packing leakage of the ills of the most vulnerable
4, flat gate valve is turned off Automatic removal of the cavity pressure, to ensure safety
5, fully enclosed, protective properties, and can adapt to weather requirements
