What is the principle of quick filling of pneumatic ball valve?
The pneumatic ball valve for quick filling includes pneumatic actuator and valve body. The pneumatic actuator and valve body of the product are connected through a coupling shaft. The pneumatic actuator of the product is provided with air source inlet, air source outlet and indicator contact. The valve body of the product is connected with the pipe coupling interface through a nut. The valve body is provided with a sphere and an "O" ring. The "O" ring of the product has two and is respectively arranged at the left and right ends of the sphere, the "O" ring of the product and the ball are provided with polytetrachloride sealing packing, and the raw material of the valve body of the product is plastic.
Pneumatic ball valveIt includes a valve body, a valve core and a valve stem. The valve core is linked with the valve stem. The valve body of the product is provided with a cylinder. The displacement of the piston rod of the cylinder is linked with the rolling of the valve stem. The opening and closing of the valve are controlled by the cylinder, and then the movement of the cylinder can be controlled by an external solenoid valve or a hand valve, and then the opening and closing of the valve can be controlled remotely, and then more convenient.
In order to avoid the wear, erosion and cavitation of the surface of the internal parts (valve core and valve seat) of the pneumatic ball valve, the thermal hardness of the data should be considered under high temperature conditions to prevent the change of metal hardness. Under high pressure difference, most of the energy of the fluid is concentrated in the valve internal parts for release, which may overload the valve internal parts. At high temperature, the mechanical properties of most of the data become worse and the data become soft, which greatly affects the service life of the valve internal parts.
Pneumatic ball valve only need to use pneumatic actuator with air source to rotate 90 degrees of operation and a small rolling torque can be closed tightly. Thoroughly equal body cavity for the medium supply resistance is very small, straight-through flow.
It is generally believed that the ball valve is suitable for direct opening and closing. The primary feature of the ball valve is its own compact structure, easy to operate and repair, suitable for water, solvents, acids and natural gas and other general operating media, but also suitable for poor operating conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined.
