The structure of the diaphragm valve is significantly different from that of general valves. It is a unique type of valve and a special form of shut-off valve. Its opening and closing component is a diaphragm made of soft material, which separates the valve body cavity from the valve cover cavity and the driving components. It is now widely used in various fields. Common types of diaphragm valves include rubber-lined diaphragm valves, fluorine-lined diaphragm valves, unlined diaphragm valves, and plastic diaphragm valves.
A diaphragm valve is equipped with a flexible diaphragm or a combined diaphragm inside the valve body and valve cover. Its closing component is a compression device connected to the diaphragm. The valve seat can be weir-shaped or the wall of a straight-through flow channel. The advantage of the diaphragm valve is that its operating mechanism is isolated from the medium pathway, ensuring the purity of the working medium and preventing the possibility of medium impact on the operating components in the pipeline. Additionally, no separate sealing is required at the valve stem unless used as a safety measure when controlling hazardous media. In diaphragm valves, since only the diaphragm and the valve body come into contact with the working medium, both can be made from various materials, making this valve ideal for controlling a wide range of working media, especially those with chemical corrosiveness or suspended particles. The operating temperature of diaphragm valves is typically limited by the materials used for the diaphragm and the valve body lining, with a working temperature range of approximately -50 to 175°C. Diaphragm valves have a simple structure, consisting of only three main components: the valve body, the diaphragm, and the valve head assembly. The valve is easy to disassemble and maintain quickly, and diaphragm replacement can be completed on-site in a short time.
