The diaphragm valve is a special form of shut-off valve whose opening and closing member is a diaphragm made of a soft material that separates the valve body cavity from the bonnet cavity. The diaphragm valve is actually just a “ clamped †valve. An elastic, disturbing diaphragm is attached to the compression member by a screw. The compression member is operated by the valve stem to move up and down. When the compression member rises, the membrane The diaphragm is lifted up and creates a path. When the compression member is lowered, the diaphragm is pressed against the valve body (if it is a å ° valve) or pressed against the bottom of the contour (if it is straight-through), the diaphragm valve is suitable for switching and throttling. Use.
The structural design of the diaphragm valve itself is particularly suitable for ultra-pure media or heavily contaminated liquids, gases, corrosive or inert media. When combined with control equipment, diaphragm valves are a better alternative to other traditional control systems, especially for solid and contaminated inert media. Products are mainly used in pharmaceutical, food industry; and power, chemical, electroplating, industrial water treatment and other industries, also used in the production of semiconductor wafers, the diaphragm valve is particularly suitable for transporting corrosive, viscous Fluids, such as mud, food, pharmaceuticals, woven adhesives, etc., because the operating mechanism of the diaphragm valve in the pipeline is not exposed to the transport fluid, so it is not polluting, and does not require filler, stem packing It is also impossible to leak.
Diaphragm valve is a special form of cut-off valves, which open and close this is a piece of soft quality materials produced by the divide, it separate the inside body and inlet inside the cover. diaphragm valve is really only "jaw" valves, a flexible, three of diaphragm by Lo underground link in compressed pieces, the compression of which is operated by stem next movement when compressed pieces rise diaphragm on hold, resulting in access, when compressed pieces falling, diaphragm pressure on the weir in valve body ( Even for the weir-type valves) or pressure at the bottom contours (even for straight-through processing), diaphragm valve applicable to switches and reducing use.
Diaphragm valve own special reasons for the structural design suitable for super pure medium or severe pollution very ropy liquids, gases, corrosive or inert medium. Combined with control equipment, diaphragm valve replace other more traditional control systems, especially vulnerable pollution applicable to solid inert medium . Biological products are mainly used in the pharmaceutical, food, industry; And the power, chemical, electroplating, and industrial water treatment industries, was also applied to the semiconductor wafer production, diaphragm valve particular applicable to the delivery of a corrosive, became the Fluid, such as mud, food, medicines, woven together liquid-dimensional, because pipelines, diaphragm valve operating agencies, it is not exposed to the delivery of fluid, So no polluting, and do not need to fill, the Department can not fill Stem will leak.
