The flat-plate gate valve is a slide valve with its closure member as a parallel wedge disc and the apparatus on the mouth of the petroleum and natural gas extracting well is just the said valve,with its closure member to be either a single wedge disc or a double one with an unfurling mechanism
therein.The pressing force of the wedge disc towards the seat ring is controlled by the medium pressure acting on the floating wedge disc or seat ring.The said valve features a small flow resistance,similar to that of a short straight pipe and without necking.The flat-plate gate valve with diversion holes is mounted on a pipeline and can do pipe cleaning directly with a pipe cleaner.As the wedge disc slides on the surfaces of the two seat rings,so the flat-plate is also applicable for the medium with suspended grains.The sealing face of the said valve is positioned automatically in fact and will not get gamaged along with the hot deformation of the body and overloaded along with the hot extension of the stem when the valve is closed in cold state.The flat-plate gate valve without diversion holes will not ask the closed positon of the wedge disc for a higher precision when the valve is closed.
