Pneumatic emergency shut-off valve is usually composed of two parts: pneumatic actuator and shut-off valve. A pneumatic actuator is a pneumatic device that drives the action of a shut-off valve, while a shut-off valve is a valve that controls the flow of gas in a pipeline. The design of this valve is very user-friendly, it has a manual operation function, which can be operated manually in an emergency, ensuring that the gas in the pipeline does not leak.
The working principle of the pneumatic emergency shut-off valve is that when the gas pressure in the pipeline reaches a certain value, the pneumatic actuator will drive the shut-off valve to close quickly, thereby cutting off the gas source. At the same time, the pneumatic actuator will also trigger an alarm device to notify relevant personnel of the abnormal gas pressure in the pipeline, so that measures can be taken to deal with it in time.
The advantage of pneumatic emergency shut-off valve is that it has the advantages of fast response, high efficiency and reliability, safety and reliability. When the gas pressure in the pipeline is abnormal, the pneumatic actuator will instantly drive the shut-off valve to close, so as to cut off the gas source and avoid accidents. In addition, the pneumatic emergency shut-off valve also has a manual operation function, which can be operated manually in an emergency, ensuring that the gas in the pipeline does not leak.
Pneumatic emergency shut-off valve is a very important industrial safety equipment, which is widely used in petroleum, chemical, gas and other industries. It has the advantages of rapid response, high efficiency and reliability, safety and reliability, and can quickly cut off the gas supply in an emergency to avoid accidents.
