The performance of pneumatic actuator as an important part of pneumatic valve
At present, a pneumatic actuator is the most critical tool in a pneumatic valve. As a pneumatic actuator, its function in the valve is to make the valve device more convenient in use. And due to the access of the pneumatic actuator, the valve can drive the rapid linkage of the valve body parts when it is operating in the pipeline, which has a certain automation effect, and because the actuator itself is driven by energy, it is very important for the valve. The drive of the valve body opening and closing parts also has a certain value. This kind of valve is used to open and close the fluid pipeline due to its low fluid resistance.
As an opening and closing device, the pneumatic actuator installed in this valve uses compressed gas to push the piston to make the valve stem connected to the valve work, and drive the ball valve sphere to move, thereby regulating the fluid medium in the pipeline. effect. As the opening and closing part, the ball rotates around the axis of the ball valve, which has a certain effect on the transportation of the medium. The characteristics of the ball valve are wear resistance, better sealing performance, and because of the lower resistance, the internal valve body suffers less wear and has a longer service life. This feature makes this pneumatic valve more effective in the use of pipelines. Handy".
