What is diaphragm valve?
A diaphragm valve is a valve that uses a flexible diaphragm to control the flow of liquid or gas. Diaphragms are typically made of rubber, plastic, or similar materials, and are positioned to allow or restrict the flow of the substance being conditioned. This type of valve is often used in applications that require high precision and control, such as the pharmaceutical and food processing industries. Diaphragm valves are known for their reliability, ease of maintenance, and ability to handle corrosive or abrasive fluids.
How the diaphragm valve to work?
Diaphragm valve is a flexible diaphragm attached to the compression member. The compression member is operated by the valve stem to move up and down. When the compression member rises, the diaphragm will be exalted to form a path. When the compression member falls, the diaphragm will be pressed on the valve body, the valve is closed. This valve is suitable for opening and closing, throttling. Diaphragm valve is especially suitable for transporting corrosive, viscous fluids, and the valve's operating mechanism is not exposed to the transport fluid. It will not be contaminated, and does not require packing, stem packing part will not leak.
What is the purpose of diaphragm valves?
1, Controlling Flow:
Diaphragm valves can be used to regulate the flow in a pipeline by opening or closing the valve. With its unique design, the valve can be fully open, fully closed. or any intermediate position between these two states, thus controlling the flow rate and pressure of the fluid in the pipeline.
2, To prevent leakage:
The structure of the diaphragm valve contains a diaphragm, which can effectively isolate the fluid in the pipeline, thus preventing liquid leakage. Because the diaphragm material has good corrosion resistance and wear resistance, so the diaphragm valve in corrosive liquids, high-temperature liquids and liquids that are easy to crystallize and other occasions can also operate normally.
3, To prevent pollution:
The diaphragm valves can form a closed space inside the valve. It can avoid the fluid in the pipeline and the environment of air, dust and impurities such as mixing. This structure can effectively prevent contamination and cross-infection. So the diaphragm valve is widely used in the pharmaceutical and food industries.
4, Regulating pressure:
The diaphragm valve can regulate the pressure in the pipeline by controlling the opening and closing of the valve. When the pressure in the pipeline exceeds the rated value of the valve, the diaphragm valve will automatically close. thus protecting the pipeline and equipment from excessive pressure damage.
5, Adapt to a variety of media:
The diaphragm valve can adapt to a variety of media, including gases, liquids, high viscosity fluids and suspensions. This is due to its structure in the diaphragm can be adapted to different media. So as to ensure the normal operation of the valve and control effect.
