Performance and Selection of Pneumatic Ball Valve

Pneumatic ball valveThe structure is a ball and two sealing seats are enclosed in the middle of the left valve body and the right valve body. When the sphere is in a closed position, the medium force effect at the upstream end is on the sphere, making the sphere tightly press the sealing seat at the downstream end, and a working specific pressure occurs. When the working specific pressure is greater than the required sealing specific pressure, an effective seal is obtained.
In order to ensure that a medium effect force can occur when the ball is in the closed position, the pneumatic ball valve ball needs to be tightly attached to the sealing seat and interference is required when the pneumatic valve and the pneumatic actuator are installed in advance, resulting in a pre-tightening specific pressure, which is the sealing specific pressure required by the 0.1 and is not less than 2Mpa. The acquisition of this pre-tightening ratio pressure is entirely guaranteed by the planned geometric dimensions.
Pneumatic ball valve is used in the process industry, pneumatic valve to withstand the pressure shake and temperature shake, when the filling type sealed ball valve defects are highlighted.
The primary feature of pneumatic ball valve is its compact structure, easy operation and maintenance, suitable for water, solvent, acid and natural gas and other general operating media, and also suitable for poor operating conditions of the medium, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be all or combined.
Pneumatic ball valve is mainly divided into pneumatic ball valve, pneumatic V type ball valve, pneumatic high pressure ball valve, pneumatic lining fluorine ball valve and other products. The pneumatic ball valve switch is light, small in size, can be made into a large diameter, reliable in sealing, simple in structure, and convenient in maintenance. The pneumatic ball valve can be widely used in many environments. It can reasonably realize the control and adjustment effect of the flow and prevent It causes danger due to uneven flow, or causes obstacles to the project.
While feeling the effect of the valve, we should also actively understand the related problems of the pneumatic valve, and select a suitable pneumatic valve to improve the efficiency and value of operation and reduce the trouble. What factors need to be considered when selecting a suitable pneumatic ball valve:
In the selection of the pneumatic ball valve, the first need to consider the use of safety features. No matter what kind of equipment, the use of safe, stable operation is often welcomed by everyone and sought after. The valves are the same. In the process of selection, the use of the valve can not affect the circulation of the material, and will not be directly touched with water or other liquid objects, to avoid affecting the sealing effect of the valve, and then can not accurately achieve the effect of the valve.
