Pneumatic piston to cut off the structure and principle of pneumatic valve

ZSQK type pneumatic cut pneumatic valve by pneumatic piston under normal temperature, medium temperature to cut off the pneumatic valve for my company to develop new products for the first time, by the domestic first introduced aerodynamic single spring actuator and high flow resistance of cut off the pneumatic valve, double sealing structure, executive body movement speed, thrust, with automatic reset function, pneumatic valve flow unobstructed, flow coefficient, pneumatic valve core seat elastic and rigid cascade double seal, the appearance of novel and unique structure makes this product is a kind of fast cutting, sealed tight, safe and reliable high-performance new cut off the pneumatic valve.

pneumatic piston to cut off the structure and principle of pneumatic valve

pneumatic piston to cut off the pneumatic valve by pneumatic piston type actuators and straight stroke adjusting mechanism composition, composed of stent edge in the middle. According to the regulating mechanism in the form of a pneumatic piston to cut off the pneumatic valve can be divided into direct single seat to cut off the pneumatic valve ( ZSQP type) , through the sleeve to cut off the pneumatic valve ( ZSQM type) , two three links to cut off the pneumatic valve ( ZSQN type) Three kinds of model. Pneumatic piston actuator has a single function ( Spring return) And double action ( The double inlet) Two. USES the single-acting actuator, the machine works can be divided into gas closed type ( Horizontal line through) And open ( Horizontal line disconnect) 。 Pneumatic piston to cut off the pneumatic valve has a hard seal and soft seal two seal forms, respectively applicable to different temperature and pressure. ZSQM type pneumatic piston sleeve to cut off the pneumatic valve adopts balance type pneumatic valve core, cut off the pressure difference can be improved. Two tee off pneumatic valve adopts pneumatic valve body four general formula, there are three stream crossings, especially suitable for switching of two flow paths.

ZSQK type pneumatic cut off the working principle of the pneumatic valve:
ZSQK type flameproof pneumatic cut pneumatic valve when the signal pressure is zero, because of the spring ( Single acting only) The pre-tightening force, make the pneumatic valve core in the initial state ( Normally open or normally closed) 。 When the received signal pressure actuator ( 。 ~。 MPa） , the compression spring driven push rod, pneumatic valve, pneumatic valve core moves to limit position, the pneumatic cut-off pneumatic valve fully open or close. Medium of the pipe connected, cut off or switch between line control. With two tees electric pneumatic valve, make the piston to cut off the pneumatic valve control more convenient and simple.
it receives signals from the monitoring instrument, fluid control technology of the pipe cutting and connected or switch port. The product has a large operating force, the aerodynamic body design is novel, small flow resistance, large rated flow coefficient, allowable differential pressure big sealed performance is good wait for an advantage. Therefore widely used in petroleum, chemical, metallurgy, electric power, textile and other industrial sector production process automatic control and remote control system.
