A storage tank can be added to the mutiny of the pneumatic actuator. The gas from the gas source must first enter the storage tank before entering the actuator. This method is better for valves with larger models or those that require more gas. Adding a storage tank Its function is not to increase the pressure of the inlet air source, but to make the pressure source tend to the temperature. The principle of this method is that the inlet pipe is small, and then the air source supply cannot keep up, resulting in a decrease in pressure. Generally, this method is used. Ways and methods allow important valves to have emergency air supply reserves.
Future Technology Development Trend of Pneumatic Actuator
If the switch is required to be faster, you can replace the pipeline through which the gas passes with a thicker one, so that the intake of the gas will increase, and the switch will naturally be faster. Install an accelerator.
In fact, when the valve is equipped with a pneumatic actuator, the on-off time requirements of the valve should be considered. Under the premise of considering all the requirements, if you consider the speed of the air intake and exhaust of the pneumatic actuator, you can choose the exhaust pipe. larger pipe diameter.
Pneumatic actuators are actuators that use air pressure to drive open, close or adjust valves, also known as pneumatic actuators or pneumatic devices, but they are generally called pneumatic heads.
Pneumatic actuators are sometimes equipped with corresponding auxiliary devices. Commonly used are valve positioners and handwheel mechanisms. The function of the valve positioner is to use the feedback principle to improve the performance of the actuator, so that the actuator can achieve accurate positioning according to the control signal of the controller.
The function of the handwheel mechanism is to use it to directly control the control valve to maintain normal production when the control system is powered off, gas out, the controller has no output or the actuator fails.
