Diaphragm valve The structural form of diaphragm valve is very different from that of ordinary valves. 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 that connects the inner cavity of the valve body with the inner cavity of the valve cover. Cavity and drive component separation 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. Diaphragm valve is a compression device with a flexible diaphragm or combined diaphragm installed in the valve body and valve cover, and its closing member is connected to the diaphragm. The valve seat can be a weir shape or a pipe wall with a straight flow channel. The advantage of the diaphragm valve is that its operating mechanism is separated from the medium passage, which not only ensures the purity of the working medium but also prevents the possibility of the medium in the pipeline impacting the working parts of the operating mechanism. In addition, there is no need to use any form of separate sealing at the valve stem unless it is used as a safety feature in controlling hazardous media. In the diaphragm valve, since only the diaphragm and the valve body are in contact with the working medium, a variety of different materials can be used. Therefore, the valve can ideally control a variety of working media, especially suitable for media with chemical corrosiveness or suspended particles. The operating temperature of a diaphragm valve is usually limited by the materials used for the diaphragm and valve body lining. Its operating temperature range is approximately ~°C. The diaphragm valve has a simple structure and consists of only three main components: the valve body, diaphragm and valve head assembly. The valve is easy to disassemble and repair quickly. Replacing the diaphragm can be done on site and in a short time.
