A flat gate valve is a sliding valve that closes a parallel gate. The closure may be a single shutter or a double shutter with a distraction mechanism in between. The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or the floating valve seat. If it is a double gate plate gate valve, then the two gates to see the distraction agencies can add this pressure. Flat gate valve features: 1, fully enclosed structure, good protective performance, can adapt to all-weather requirements 2, the flat gate valve automatically closed off when the cavity high pressure to ensure safe use 3, at full open, the channel is smooth to a straight line, flow resistance Coefficient is very small, no pressure loss, can pass the hair ball cleaning pipeline 4, seat with O-ring seal and preload force of the floating valve seat structure, so that the import and export of flat gate valve two-way seal; and the structure of the opening and closing torque Only ordinary valve 1/2, can easily open and close the valve 5, with a self-sealing filler structure, without frequent adjustment, open, off extremely light, and the seal is reliable, packing letter with auxiliary sealing grease Injection structure, the sealing performance is absolutely reliable, and truly achieve zero leakage; solve the common valve packing at the most easy to drain the shortcomings of the world's highest technical level and to fill the gaps in the domestic anti-high sulfur acid special plate valve ?? CL150LB, high pressure CL900-2500LB-DN25-500 flat gate valve, has been successfully developed. At present, the product has been successfully used in the main Puguang Gas Field in China to develop ground transportation projects in the yard. It is understood that the product has the advantages of small flow resistance, large flow capacity, and clear cleaner, and has the advantages of light weight and easy opening and closing. It can be widely used in the production and transportation of sulfur-containing oil and natural gas, oil and gas pipeline, Refinery and other conditions, as a control medium circulation and closing of the hoist device. According to the needs of the project, the valve manual, bevel gear drive, explosion-proof electric drive and other means. The valve is also designed with a valve position switch instructions, stem protection cover, to prevent misuse of the protection lock, etc., to ensure the safe operation of the valve to prevent misuse. The product uses a single gate hard seal, floating patented valve seat, to ensure that debris will not enter the back of the seat, with fire and anti-static function, the valve rough casting for the company smelting, casting. Special structure of the patented flexible fire valve seat, to overcome the limitations of the past can only be used O-ring, the elastic valve seat plate gate valve applications extended to the field of high temperature and high pressure. High-pressure plate gate valve in October 2007 has been organized by the relevant departments of Sinopec and China Petroleum Design Institute and the University of Professional, China Shenhua Group, China Valve Association experts conducted a provincial commissioning appraisal, the State Patent Office in 2008 approved the patent (Patent No .:). Experts believe that the successful development of the valve and its application to promote the province's machinery and oil industry, efficient economic and technological play a key role in the country also had a greater impact in the market has a very broad application prospects.
