Description
Technical field
A kind of flat gate valve of this utility model design, specific design one reasonable in design, easy to use, good seal performance, the manual flat valve of the high sealing performance that resistance to pressure is good.
Background technology
Flat gate valve is a kind of closure member is the slide-valve of parallel gate plate. Its closure member can be single disc or the double disc therebetween with spreading mechanism, and flashboard is controlled by the pressure medium of effect with floating flashboard or floating valve seat to the thrust of valve seat. If double disc flat gate valves, then the spreading mechanism between two flashboards can supplement this thrust. Flat Sluice is widely used on the feed-line such as oil product, natural gas.
The flat gate valve structural design of prior art is unreasonable, poor sealing performance, and pressure performance is not good, and service life is shorter, installs assembling cumbersome.
