Principle of pneumatic two-stage ball valve
Two-stage pneumatic ball valve and pneumatic piston two-stage globe valve is a globe valve which can realize two-step opening or two-step closing. It is a special pneumatic valve, providing 0, 45, 90 or 0, 90, 180 three-position operation mode. It consists of two-stage pneumatic actuator, ball valve or butterfly valve. By changing the piston stroke of the additional cylinder, the angle of the actuator and the valve is stopped in advance. Because of the quick exhaust and throttling functions in the actuator, the two-stage ball valve has excellent switching characteristics. Therefore, the opening and closing speed of the valve is slow, the fluid in the pipeline changes smoothly, the combustible fluid will not explode due to the water hammer phenomenon caused by the impact, and the flowmeter and other instruments in the system will not be damaged due to the impact. It is suitable for the flow control system of petroleum, chemical industry, light industry, national defense and other industries, especially for the oil storage and transportation system.
