Diaphragm Valve Function

Diaphragm valve is a common industrial valve, its main role is to control and regulate the flow of fluid in the pipeline. Diaphragm valve Because of its unique structure and working principle, the diaphragm valve is widely used in chemical, food, pharmaceutical, water treatment and other fields. In this article, we will delve into the main role of diaphragm valves and their working principles.1, control flow: diaphragm valve can adjust the flow in the pipeline by opening or closing the valve. With its unique design, the valve can be fully opened, fully closed or any intermediate position between these two states to control the flow speed and pressure of the fluid in the pipeline. 2, prevent leakage: the structure of the diaphragm valve contains a diaphragm, which can effectively isolate the fluid in the pipeline, thereby preventing liquid leakage. Because the diaphragm material has good corrosion resistance and wear resistance, the diaphragm valve can also operate normally in corrosive liquids, high-temperature liquids and liquids that are easy to crystallize.3, to prevent pollution: diaphragm valve can form a closed space inside the valve, so as to avoid the fluid in the pipeline and the environment of air, dust and impurities mixed. This structure can effectively prevent contamination and cross-infection, so diaphragm valves are widely used in pharmaceutical and food industries.4, adjust the pressure: the diaphragm valve can adjust the pressure in the pipeline by controlling the opening and closing of the valve. When the pressure in the pipe exceeds the valve rating, the diaphragm valve automatically closes, protecting the pipe and equipment from high pressure damage.5, adapt to a variety of media: diaphragm valves can adapt to a variety of media, including gases, liquids, high-viscosity fluids and suspensions. This is because the diaphragm in its structure can adapt to different media, so as to ensure the normal operation and control effect of the valve.
