Pneumatic ball valves are usually composed of electric actuators and valves. With electric energy as the power, connect the electric actuator to drive the valve to realize the switching and regulating function of the valve, so as to switch or regulate the pipeline medium. The motor of the electric actuator needs to rotate forward and backward to open or close the valve. What is the product advantage of the pneumatic ball valve?
1. Simple structure
The main body of vacuum valve is composed of the valve assembly, the electric actuator and the connector between the electric actuator and the valve assembly. The pneumatic ball valve is powered by electric energy, connected with the electric actuator to drive the valve, and controlled by the electric actuator drive device, so as to realize the opening and closing action of the valve and achieve the purpose of opening and closing the pipeline medium. The excellent service and product structure of the pneumatic ball valve are relatively simple.
2. Easy adjustment
Manually turn the valve of the pneumatic ball valve to the fully open position with the hand wheel, set the travel switch and torque switch, press and lock the clutch screw of the counter with a screwdriver, and turn the adjusting screw of the travel switch clockwise until the rotary cam of the travel switch acts. Open the travel setting, disengage the clutch screw, adjust the opening torque switch, loosen the adjusting screw of the opening torque switch, adjust the opening torque switch to the required setting value, tighten the adjusting screw of the opening torque switch, and the use of the pneumatic ball valve is closely related to its working mode.
3. Good effect
The pneumatic ball valve completely eliminates the possibility that the radioactive gas in the primary circuit leaks to the plant area due to the drainage of the pressure relief tank, which leads to the alarm of the gas discharge system exceeding the threshold value and the power reduction or shutdown of the unit. After the technical transformation, the leakage of radioactive gas in the primary circuit to the plant area caused by the drainage of the pressure relief tank is completely eliminated, the radiation psychological burden of the staff is eliminated, and the probability of human error is reduced. This is also a major product advantage of the pneumatic ball valve.
After the protective device is installed, the display screen of the pneumatic ball valve actuator can not only block the direct sunlight, but also have the effect of clear screen, slow down the aging speed of the display screen of the pneumatic ball valve actuator, and extend the service life. When the valve cover is pulled down, the valve cover can be clearly displayed. When the valve cover needs to be pulled, the valve cover can be opened.
