Plastic valve diaphragm valve

Diaphragm valve

Diaphragm valve is composed of valve shell and equivalent diaphragm valve core, its working mechanism is composed of the diaphragm movement. In the middle of the valve shell has a sealing seat, diaphragm through the handwheel operation lift to open and close the flow channel.

The internal structure of the body is very simple, and the inner surface of the body is usually lined with glass, enamel, synthetic resin, rubber, etc., the diaphragm lined with rubber and synthetic resin etc. These valves are suitable for corrosive fluids, because they have smooth flow, is often used in the mud

Leverage the relief valve - a weight is placed on one end of the lever, the valve core are loaded at the other end.

Spring balance valve - lever is loaded to balance the load of valve core.

Other - to prevent an explosion caused by pressure rise, also want to ensure that the necessary air tightness in working status, in this case, can be made from thin sheet metal explosion-proof membrane type safety device.

Relief valve for steam and gas, safety valve used in a slightly different operation mechanism of the liquid. The provisions of the relief valve is very much, so when the choice, the most important thing is to adapt to the rules.

Steam trap, automatically remove condensate from the steam pipe. A disc, ball float, double vertical, bucket of gold.

Other special valves including rubber, synthetic resin lining shell, with closed flow path of the throttle valve and vacuum valve for vacuum system.
