Pneumatic ball valve principle
Pneumatic ball valve includes pneumatic actuator and valve body. The pneumatic actuator of this product is connected with the valve body through the connecting shaft. The pneumatic actuator is equipped with air inlet, air outlet and indicating contact. The valve body is connected to the pipe seat by a nut. Body with ball and ball "O" ring. There are two types of products "O" with rings on the left and right sides of the sphere. O Carbon tetrachloride packing carbon tetrachloride packing. The material of the valve body is plastic. Pneumatic ball valve is composed of a valve body, a spool and a stem. The spool is connected with the stem. This product has a cylinder on the valve body. The displacement of the cylinder piston rod is connected to the rolling rod of the valve stem. The opening and closing of the valve is controlled by the cylinder to make it easier. External solenoid valve or manual valve can control the movement of the cylinder, so that the valve switch remote operation, more convenient. Pneumatic ball valve can only be closed when the pneumatic actuator and air source rotate 90 degrees and the rolling torque is small. The fully equal inner cavity of the body provides small resistance and DC channel for the medium. Ball valves are generally considered to be suitable for direct switching. Ball valves are characterized by compact structure, easy operation and maintenance. Suitable for poor working conditions of media, such as water, solvent, acid, natural gas, oxygen, hydrogen peroxide, methane, ethylene, etc. Integral or combined ball valve body.
Pneumatic ball valve is a ball valve equipped with pneumatic actuators. The speed of the pneumatic actuator is relatively fast. Fast switching speed is 0.05 seconds/time, so it is also called pneumatic quick cut off ball valve. Pneumatic ball valves are usually equipped with solenoid valves, air source processing tees, limit switches, positioners, control boxes and other accessories to achieve local control and remote centralized control. Valves can be controlled in the control room, without the need to reach the site or high altitude hazardous areas for manual control, greatly saving labor, time and safety.
