GJ841X pneumatic pipe clamp valve working principle

When controlling the input of the medium, the cavity between the rubber sleeve and the valve body communicates with the atmosphere, and the rubber sleeve is in an outwardly tensioned state by the fluid pressure, because the reinforcing sleeve of the sleeve is arranged at an angle to make the sleeve axially The radial pressure is balanced with each other, so the length and diameter of the sleeve are not changed by the pressure of the fluid. When the control medium enters the sleeve of the sleeve and the valve body, the rubber sleeve is deformed and intercepted under fluid pressure.
