Sanitary Diaphragm Valve is a valve with a flexible diaphragm or a combined diaphragm installed in the valve body and the valve cover, and its closing part is a compression device connected to the diaphragm. The valve seat can be a weir shape or a pipe wall of a straight-through flow channel. The advantage of the sanitary 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.
The main advantage of the sanitary 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, no separate seal of any form is required at the valve stem unless it is used as a safety facility in controlling harmful media.
In the sanitary diaphragm valve, since the working medium contacts only 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. The sanitary diaphragm valve is particularly suitable for media with chemical corrosiveness or suspended particles. The operating temperature of the diaphragm valve is usually limited by the materials used for the diaphragm and the valve body lining, and its operating temperature range is approximately -50 to 175°C.
The strength test of the sanitary diaphragm valve introduces the medium from either end, opens the valve disc, and closes the other end. After the test pressure rises to the specified value, check whether the valve body and valve cover have any leakage. Then reduce the pressure to the sealing test pressure, close the valve disc, open the other end for inspection, and pass the test if there is no leakage. Sanitary diaphragm valves are used in places with high hygiene requirements such as pharmaceuticals, biology, and purified water treatment. The structural design of the diaphragm valve itself is particularly suitable for ultra-pure media or heavily polluted, very viscous liquids, gases, corrosive or inert media. When combined with control equipment, the diaphragm valve can replace other traditional control systems, especially for solid and easily contaminated inert media. The diaphragm can also be replaced after long-term use.
