In what situations can the sanitary diaphragm valve be used? Sanitary diaphragm valve related information: when the process requires cleanliness (food, cosmetics, medicine, etc.), no foreign substances are allowed to contact the medium during the production process. If a ball valve is used, the cleanliness of the production process cannot be guaranteed. Only the diaphragm valve can To do so, at this time, a diaphragm valve will be used. The most prominent feature of the diaphragm valve is that the diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve stem, valve clack and other parts located above the diaphragm are not corroded by the medium, and the packing seal structure is omitted, and no medium is generated. Leakage. The diaphragm made of soft seal such as rubber or plastic has better sealing performance. Diaphragm valve is a special form of shut-off valve. Its opening and closing part is a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the valve cover and the driving parts. Diaphragm valve is an elastic, disturbable diaphragm, which is connected to the compression part with bolts. The compression part is operated by the valve stem to move up and down. When the compression part rises, the diaphragm is lifted high, which creates a passage. When descending, the diaphragm is pressed on the valve body weir (if it is a weir valve) or at the bottom of the contour (if it is a straight-through type), the diaphragm valve is suitable for switching and throttling. 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 better replace other traditional control systems, especially suitable for solid and easily polluted inert media. Products are mainly used in biopharmaceuticals, food, industries; and industrial water treatment in power, chemical, electroplating, and other industries. They are also used in the production of semiconductor wafers. Diaphragm valves are especially suitable for transporting corrosive and viscous products. Fluids, such as mud, food, medicines, fabric adhesives, etc., because the operating mechanism of the diaphragm valve in the pipeline is not exposed to the transport fluid, it is not polluting and does not require packing. The valve stem packing part It is impossible to leak.
