Description
Technical field
A kind of flat gate valve of this utility model design, specific design one reasonable in design, easy to use, manual flat valve 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. The flap type of prior art, when pressure medium is low, the sealing force of metallic sealing section is not enough to reach satisfied sealing. Contrary to pressure medium height, if sealing surface lubricates without system media or exotic mediums, often open and close it is possible to make sealing surface wear excessive. Additionally on circular flow channel, the flashboard of transverse movement is only when it is in the 50% of valve off position, and this valve is just more sensitive to the control of flow. And, flashboard, when interrupting at a high speed with high-density medium stream, can produce high vibration. Service life is shorter, and installation assembling is cumbersome, has certain deficiency.
