TH-VDP Valve Disc/Plate, Flap (TH-VDP) Description
he Valve flap is the opening and closing part of the valve, mainly refers to the check valve and the globe valve.
The opening and closing parts of butterfly valves are called butterfly plates, the opening and closing parts of gate valves are called gate plates, the opening and closing parts of globe valves and check valves are called valve flaps, and the opening and closing parts of plug valves are called plug bodies.
Globe valves are usually limited to nominal diameters below 250 mm because the opening and closing torques of globe valves are relatively large and the length of the structure is long
Here we are mainly talking about the butterfly valve disc, which is installed in the diameter direction of the pipeline. Butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. In the cylindrical channel of the valve body of the butterfly valve, the disc-shaped butterfly plate rotates around the valve shaft to achieve opening and closing, and the rotation angle is between 0° and 90°. When it is rotated to 90°, the valve is fully open.
The butterfly valve disc is divided into Center-line valve plate, double shaft valve plate, pin-less valve plate.
The valve plate of the traditional butterfly valve is entirely in the form of a rigid body. For high-pressure large-diameter butterfly valves, the force of the medium acting on the surface of the butterfly plate is very large, and the amount of deformation of the valve plate in the form of a rigid body is large, resulting in difficulty in reverse sealing. , The positive sealing pressure is too large, and the opening and closing torque is large.
The valve can be used to control the flow of various types of fluids such as air, water, seawater, steam, various corrosive media, mud, oil, liquid metals and radioactive media. Mainly cut off and throttle the pipe. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening, closing or adjusting.
The valve disc is the opening and closing piece that controls the flow and circulation of the medium. It plays a vital role in the entire valve structure. It can be operated by the handle or by turbine, pneumatic, electric and other equipment. The quality of the valve disc determines the overall performance of the valve. The smoothness of the contact surface between the valve disc and the rubber seat determines the quality of the valve’s tightness.
The material of the valve disc is mainly: ductile iron, stainless steel, aluminum bronze, etc.
The structure of the valve disc mainly includes: Center-line valve plate, double shaft valve plate, pin-less valve plate, etc.
The main colors are: blue, silver, red, blue, etc.
