Diaphragm valve is a kind of special mode block valve. Its disc is made by a soft material and separates body cavity with the valve cover cavity and drive components, so it is called diaphragm valve. It is a kind of block valve which adopts spring diaphragm as disc and sealing element.
Valve clack, valve rod, valve deck etc parts are located on the upper diaphragm and are divided with fluid and doesn't be etch by fluid, at the same it also prevent rust and other impurities pollution.
The service life of Diaphragm valve depends on its fatigue durability. It is suitable for corrosive fluids and requires cleaning fluid, such as acetic acid, chemical fiber and boiler softened water. Its working pressure is not more than 0.6MPa, working temperature is less than 100º C, and normal diameter is not more than 350mm.
The most prominent features of Diaphragm valve is that diaphragm separates the bottom body cavity and top cover body cavity. Valve rod, valve clack etc parts are not subject to corrosion medium and save packing seal structure and don't produce leakage.
1. Diaphragm is made by rubber or plastic etc soft sealing materials; Its sealing function is good.
2. The materials of diaphragm are limited and Diaphragm valve are suitable for low pressure and low temperature occasion.
3. Diaphragm valve is divided according its structure: Straight-flow, straight-through type, flashboard type, right angle etc; Connection type is flanged type; According its drive type to divide into manual drive, electric drive and pneumatic drive.
4. It should not be commonly used for temperature higher than 60 degrees and organic solvents and strong oxidizing medium pipeline, unfavorable also used in high pressure pipeline.
