[Valve features]

1, the gate has two sealing surfaces, the sealing surface to form a wedge, wedge angle varies with valve parameters, usually 5 degrees.
2, wedge gate valve sealing principle is combined by two on the two upper wedge sealing surface and sealing surface of the valve body wedging, thereby sealing performance.3, wedge gate valve according to the stem drive gate opening and closing different ways, can be divided into bright rod gate valve (lift rod gate valve) and dark rod gate valve (rotary rod gate valve).
4, wedge gate valve in accordance with the different forms of the gate structure, can be divided into elastic gate valve and rigid gate valve.
5, the valve body for casting molding, valve body and valve cover with bolt connection, the middle flange using spiral gasket seal, the customer has special requirements can also be used metal ring connection.
6, the channel is smooth, the flow coefficient is small. The sealing surface is eroded and eroded by medium.
7, The sealing surface is made of alloy steel or hard alloy. It has good abrasion resistance and scratch resistance.
8, flexible graphite packing, reliable sealing, easy and flexible operation.
9, medium flow unrestricted, no disturb, do not reduce pressure.
10, The shape is simple, the structure length is short, the manufacturing technology is good, and the scope of application is wide.

[Adaptive condition]
       The valve has the advantages of light switch, reliable sealing, good elasticity memory and long service life. The utility model can be widely used as an adjusting and intercepting device for pipelines such as water supply, sewage, building, petroleum, chemical industry, food, medicine, light industry, electric power, ship, metallurgy, energy system, etc..
