What is special about wedge gate valve in structure design?
The switching element of wedge gate valve is gate valve. The working direction of the indenter and the direction of the fluid form 90 degrees to each other. Wedge gate valve can only be fully opened or closed, and can not be adjusted or throttled. Wedge gate valves have two sealing surfaces. The two sealing surfaces of wedge gate valve are wedge-shaped. The parameters of wedge gate valve vary, usually 5, and the medium temperature is not 252 '.
Wedge gate valve has a flat sealing surface and vertical centerline, so the sealing surfaces of oil passage plate and gate are parallel to each other. This wedge gate valve is usually of the double gate type so that when closed, the body is in close contact with the two protruding surfaces of the gate. Wedge gate valves usually have two thrust wedges sandwiched between two gates. In this way, when the valve is closed, the double thrust block contacts with the bottom of the valve body and is gradually supported, the double brake pads are pushed away, and the sealing surface of wedge gate valve is tightly sealed with the oil circuit board. Wedge gate valve parallel gate valve is mainly used for small pipe and other low pressure pipeline. There are also single gate wedge gate valves, but very rare. Wedge gate valve is a kind of gate valve, its sealing surface and vertical center line form a certain angle. The higher the medium temperature is, the greater the inclination angle is needed to reduce the possibility of wedging into the gate slot when the temperature changes.
