Introduction
Pneumatic diaphragm valve is a special form of shut-off
valve. The 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 bonnet and the driving
parts. It is suitable for two-position adjustment,
throttling, Channel necking, low noise, cavitation, and small
operating torque.
working principle
The working principle of the pneumatic diaphragm valve is to
clamp a set of thin hemispherical metal films in the valve
body as a barrier between the valve stem and the fluid. The
valve closing is achieved by pressing the valve disc on the
valve seat by the stem head and the metal film. The valve is
opened by an internal spring. When the valve stem is lifted
out of contact with the membrane, the valve disc is
lifted.
Features
1. The valve stem, valve clack and other parts above the
diaphragm are not corroded by the medium and will not cause
medium leakage.
2. The diaphragm made of soft seals such as rubber or plastic
has good sealing performance;
3. The flexible diaphragm closes reliably, and even the dirty
liquid can be cut off well.
