What is the use of cylinder safety valve

For pressure vessels with flammable, explosive or toxic media, Cylinder safety valveThe discharged medium must have a safety device and recovery system. Lever typeCylinderThe safety valve must be installed in a vertical position and the spring span>CylinderThe safety valve is also best installed vertically to avoid affecting its action. During installation, attention should also be paid to the fit, the coaxiality of the parts, and the uniform stress on each bolt, thencylinderWhat is the function of the safety valve? CylinderThe safety valve is a safety protective valve, mainly used in pipelines On various pressure-bearing equipment, when the working pressure of the medium exceeds the allowable pressure value, the cylinder ;">The safety valve automatically opens to discharge the medium outward. As the pressure of the medium decreases, cylinderThe safety valve will close again, thus preventing the risk of overpressure in pipelines and equipment.

The pneumatic piston actuator uses compressed air as the power source, and drives the crank arm to rotate 90 degrees through the movement of the piston to automatically open and close the valve. Cylinder safety valveThe components are: adjusting bolt, actuator box, Crank arm, cylinder block, cylinder shaft, piston, connecting rod, cardan shaft.

Cylinder safety valveWorking principle:PneumaticSafety valve consists of an actuator and a regulating mechanism. The actuator is the thrust component of the regulating valve. It generates corresponding thrust according to the control signal pressure and promotes the action of the regulating mechanism. The valve body is the regulating component of the pneumatic safety valve. It is in direct contact with the regulating medium and regulates the flow of the fluid.



CylinderSafety valveis a right-angle rotary structure, which is used in conjunction with the valve positioner. Achieve proportional adjustment;the V-shaped valve core is most suitable for various adjustment occasions. It has a large rated flow coefficient, a large adjustable ratio, good sealing effect, sensitive adjustment performance, small size, and can be installed vertically or horizontally. Suitable for controlling gas, steam, liquid and other media.

is a right-angle rotary structure, consisting of a V-shaped valve body, a pneumatic actuator, a positioner and other accessories;it has an inherent flow characteristic of approximately equal ratio;it adopts double Bearing structure, small starting torque, excellent sensitivity and sensing speed;super shearing ability.
