How Does a Diaphragm Valve Work?

The diaphragm valve is a fluid control device that can control the flow of fluid by moving the diaphragm up and down. The overall structure of this valve is relatively simple, and its components include the valve body, valve cover, diaphragm and handle. To put it simply, during the operation of the diaphragm valve, the control signal reaches the valve, the handle begins to rotate, and the diaphragm begins to move up and down. When the diaphragm moves up, the fluid can pass through the valve and flow in the corresponding pipeline.

The design features of the diaphragm valve make it suitable for various liquid, gaseous and solid media. The inner cavity of the valve is composed of two diaphragms, and the medium cannot directly contact the body of the valve to prevent fluid contamination and leakage. If a fault occurs, the diaphragm can also resist pressure by itself to prevent fluid leakage from polluting the environment.

The valve core of the diaphragm valve has no shape-rotating parts, and the life of the operating parts is very long. It can play an important role in fluid control equipment in the fields of chemical industry, food processing and medicine.
