Principle and Layout Design of Diaphragm Valve

{
}

Principle and layout design of high vacuum diaphragm valveHigh vacuum diaphragm valve is a relatively special intercept valve, presented in 1920s. Its opening and closing is made of a piece of soft material diaphragm, the valve body cavity, the valve cover cavity and drive parts are from each other, so called diaphragm valve. 


High vacuum diaphragm valve is actually just a "clamp" valve, an elastic, the diaphragm can be disturbed, with studs on Cohesion in austerity, austerity is operated by stem moves up and down, when tightening pieces rise diaphragm on hold, and the formation of the passage. When the compression part is lowered, the diaphragm is pressed on the valve weir or is pressed at the bottom of the contour.

For the sanitary diaphragm valve layout design reason, it is very suitable for super puremedium, serious pollution, very viscous liquids, gases, corrosive, lazy medium, and the combination of control equipment, the diaphragm valve can replace the traditional control system, especially suitable for use in solid medium and idle polluting. 


The first commercial application is in industrial water treatment, pharmaceutical, food industry, electric power, chemical industry, electroplating industry, etc., are also used in the production of semiconductor wafer, the diaphragm valve is particularly suitable for transporting corrosive, viscous fluid, such as mud, food, medicine, fiber adhesion liquid so, because of the pipeline, the diaphragm valve operation organization, is not exposed to the delivery of fluid, so no pollution, no packing, valve stem packing department does not leak.

Adamant Valves, the main productions are gate valve, globe valve, sanitary butterfly valve, sanitary ball valve, angle valve, sanitary sampling valve, flushing sampling valve, discharge valve, valve insulation jacket, melt (three, four, five) distribution valve, gate valve, (blue type, Y type), filter double cylinder valve, hydraulic control valve, bellows globe valve, plunger valve, globe valve, plug valve, regulating valve, drain valve of high pressure valves and automatic control valves.
