The high-pressure flat gate valve is suitable for natural gas, petroleum, chemical, environmental protection, urban pipelines, natural gas pipelines and other gas transmission pipelines, exhaust systems, and steam storage equipment. The Z43 pipeline high-pressure flat gate valve is suitable for long-distance natural gas extraction and purification pipelines. According to the driving method, high-pressure flat gate valves can be divided into manual high-pressure flat gate valves, pneumatic high-pressure flat gate valves, and electric high-pressure flat gate valves.
A high-pressure flat gate valve is a type of slide valve with a closing element of a parallel nozzle. The closed part can be a single nozzle or a double nozzle, and the nozzle of the expansion mechanism is controlled by the medium pressure acting on the floating nozzle or floating plate. If the high-pressure flat gate valve is a double gate flat gate valve, the expansion mechanism between the two gates can compensate for this pressure. The high-pressure flat gate valve has a reasonable structure, reliable sealing, and easy operation. The sealing mask has excellent corrosion resistance, wear resistance, and corrosion resistance. The high-pressure flat gate valve is made of solid high-pressure flat valve alloy and can be used for throttling. The high-pressure flat gate valve adopts a self sealing packaging structure, which does not require regular adjustment. It is very light to open and has reliable sealing performance. The stuffing box adopts an auxiliary sealing and grease injection structure, and the high-pressure flat gate valve has reliable sealing performance with almost zero leakage. Invented high-pressure flat gate valves for natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines, ventilation systems, steam storage and other transportation pipelines. High pressure flat gate valves are suitable for ordinary valve filling components in natural gas extraction and purification equipment.
