The structure and form of the diaphragm valve are not the same as the traditional valve. It is a cut-off valve in a special form. This cut-off valve is a special and new type of valve. People may know a lot about traditional valves, but they don’t know much about the new generation of diaphragm valves. For example, where is the diaphragm valve generally used, and what does it do? Next, explain and analyze where the diaphragm valve is generally used.

The structure of the diaphragm valve is very different from the general valve. It is a new type of valve and a special form of cut-off valve. Its opening and closing part is a diaphragm made of soft material. The inner cavity of the bonnet and the driving part are separated and are now widely used in various fields. Commonly used diaphragm valves include rubber-lined diaphragm valves, fluorine-lined diaphragm valves, unlined diaphragm valves, and plastic diaphragm valves.

1. This valve is composed of valve body, bonnet, valve stem, valve disc, diaphragm and driving parts.

2. The opening and closing of the valve is achieved by rotating the hand wheel. When the handwheel is rotated clockwise, the valve will drop to cut off the passage; otherwise, the valve will open.

3. When the diaphragm valve is used in the water vapor pipeline with the working temperature ≤120℃, the material of the diaphragm should be heat-resistant rubber, and indicate it when ordering.
