Instructions for pneumatic control valve
In industry, various equipment and devices are needed to process various materials and media. As a device used more frequently in pipelines, valves are the main equipment for regulating the flow of media in pipelines.
At present, the valve devices used in industry generally tend to be in the form of regulation, so most of the valves used in pipelines are pneumatic control valves The main function of this pneumatic valve is to regulate the flow of the medium in the pipeline, and it has good sealing performance.
The current pneumatic valve is a relatively new type of valve device, and this way of promoting the valve through the pneumatic actuator is also the main form of automatic regulation at present.
The pneumatic actuator of the pneumatic control valve is actually the main representative of the automatic control. The difference from the electric actuator is that it uses the power generated by air compression to further promote. For the valve in the pipeline, the power drive of the pneumatic actuator makes the fitting between the hoist and the valve seat more accurate and plays a more accurate cutting effect. This is very effective for sealing and medium cutting off, so this device is also a relatively stable type. In fact, another kind of manually operated valve is one of the mainstream currently used. Although it does not have an automatic adjustment function, it is more stable, easy to operate, and easy to control. Therefore, in addition to automatic devices, Usually, manual control will be added, so that when the automatic device has problems, manual control can be used for emergency.
