The internal structure of the pneumatic actuators

Actuator using now is used more sensing devices, and internal includes adjusting mechanism and actuator two parts, the two parts and test equipment is made up of a now actuators, and the more classic mainly pneumatic actuators and electric actuators. Is currently in use in the pipeline valve more two driving devices, the use of these two kinds of driving device has now on the regulation of the pipeline system in the whole to the automation line. As a pneumatic actuator mainly include sensing device, pneumatic regulating mechanism and actuator of three parts, including sensing system is mainly for medium flow in the pipeline for testing.


when the pipes in the medium velocity is too fast or flow over a certain amount of time, the device will send out signals to pneumatic regulating mechanism, and regulatory agencies will use internal equipment will air compressor internal impetus to the actuator. When actuator gas impetus of oppression on the implementation of internal components when it comes to work, and connected to the valve stem and valve body within the open-close part also will make the corresponding movement, thus to the media in the pipeline have the effect of regulation, the composition of the actuators and driving forms.
