What is the structure of the pneumatic valve?
Pneumatic valve: a valve driven by compressed air. Structure and features: A. The purpose is a right-angle rotary structure, which is used in conjunction with the valve positioner to achieve proportional adjustment;the V-shaped valve core is most suitable for various adjustment occasions, with a large rated flow coefficient and a large adjustable ratio. It has good sealing effect, sensitive adjustment performance, small size and can be installed vertically or horizontally. Suitable for controlling gas, steam, liquid and other media. B. Features: It 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 proportions;it adopts a double-bearing structure, with small starting torque and extremely high Good sensitivity and sensing speed;super shearing ability. C. 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. Its components are: adjusting bolt, actuator box, crank arm, cylinder block, cylinder shaft, piston, connecting rod, and universal shaft. D. Working principle of pneumatic control valve: Pneumatic control valve is composed 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 regulating valve. It is in direct contact with the regulating medium and regulates the flow of the fluid.
