& Diaphragm valve: The structure of the 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. The inner cavity of the body is separated from the inner cavity of the valve cover and the driving components, and is 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 flexible diaphragm or combined diaphragm installed in the valve body and valve cover, and its closing member is a compression device connected to the diaphragm. The valve seat can be in the form of a weir or the wall of 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, any form of separate sealing at the valve stem is not required unless used as a safety feature in controlling hazardous media. In a diaphragm valve, since the working medium only contacts the diaphragm and the valve body, both of which can be made of a variety of different materials, the valve can ideally control a variety of working media, especially suitable for chemically corrosive or suspended particles. medium. The operating temperature of a diaphragm valve is usually limited by the materials used in the diaphragm and valve body lining. Its operating temperature range is approximately ~℃. The diaphragm valve has a simple structure and consists of only three main components: valve body, diaphragm and valve head assembly. The valve is easy to quickly disassemble and repair, and diaphragm replacement can be completed on site and in a short time.
