National standard pneumatic V-type regulating valve, natural gas flow control valve

National standard pneumatic V-type regulating valve, natural gas flow control valve

Usage and characteristics:

1. The purpose is a right angle rotating structure that can be used in conjunction with valve positioners to achieve proportional adjustment; The V-shaped valve core is suitable for various regulating occasions, with a high rated flow coefficient, large adjustable ratio, good sealing effect, zero sensitivity regulating performance, small volume, and can be installed vertically and horizontally. Suitable for controlling media such as gases, vapors, liquids, etc.

2. Features: It is a right angle rotating structure composed of a V-shaped valve body, pneumatic actuator, locator, and other accessories; There is an inherent flow characteristic that is approximately equal in percentage; Adopting a dual bearing structure, the starting torque is small, and it has extremely high sensitivity and sensing speed; *The cutting ability.

3. The pneumatic piston actuator uses compressed air as the power source, which drives the crank arm to rotate 90 degrees through the movement of the piston, achieving automatic opening and closing of the valve. Its components include: adjusting bolts, actuator housing, crank arm, cylinder block, cylinder shaft, piston, connecting rod, and universal joint.

4. The working principle of pneumatic control valve: Pneumatic control valve consists of an actuator and a regulating mechanism. The actuator is the thrust component of the regulating valve, which generates corresponding thrust according to the magnitude of the control signal pressure, and drives the action of the regulating mechanism. The valve body is the regulating component of a pneumatic control valve, which directly contacts the regulating medium and regulates the flow rate of the fluid.

Pneumatic V-shaped regulating valve, natural gas flow control valveWorking Principle:

When the air hole on the right is filled with air, the internal piston of the actuator moves to both sides, driving the rolling of the middle output shaft with a stroke angle of exactly 90 degrees, making the valve fully open. When the left air hole is filled with air, the internal piston of the actuator moves towards the middle, driving the rolling of the output shaft in the middle. The stroke angle is also 90 degrees, causing the valve to fully close. Simply put, it means opening the vent valve on the right side and closing the vent valve on the right side. If there is a sudden gas supply failure on site, the valve will remain in its original position.
