We are in needPneumatic actuatorAt the same time, we will choose more suitable pneumatic actuators and pneumatic actuators with higher cost performance. Then we must first understand the varieties of actuators. Actuators can be divided into pneumatic actuators and electric actuators, and the more commonly used actuators are these two. We will choose pneumatic actuators when we choose and buy.
Then we have to select the actuator according to the size of the air source, and the torque required to turn the valve. If the size is too large, the valve will not last long. Generally, it is OK to leave 30% allowance for torque.
Secondly, let's check the installation channels. Each environment selects actuators. There is a standard for actuators. We can't be wrong if we find the corresponding standard according to the valve.
With electric as the column, electric switch type. Passive contact type and conditioning type. We only need to control the valve flow according to the size of the choice.
At present, a pneumatic actuator is the key appliance in the pneumatic valve, and as a pneumatic actuator, in fact, the effect it shows in the valve is to make the valve equipment more convenient when in use. And because the pneumatic actuator access makes the valve in the pipeline operation of the time can drive the rapid linkage of the valve body parts, has a certain automation effect, and because the actuator itself is driven by power, so on the valve body opening and closing parts of the drive also has a certain value. This valve because the fluid resistance is small is used to the fluid pipeline to play the opening and closing effect.
As one of the opening and closing equipment, the pneumatic actuator installed in this valve has the advantages of using compressed gas to push the piston to make the valve stem connected to it play an effect, and drive the ball valve to move, thus playing the role of conditioning the fluid medium in the pipeline. As one of the opening and closing parts, this ball around the axis of the ball valve for rotation, on the medium transport has a certain effect. The ball valve is characterized by wear resistance, better sealing function, and because the resistance is small, so the internal valve body by less wear and tear, the service life is relatively long, so that the pneumatic valve in the use of the pipeline on the comparison of "handy".
