How does the working principle diagram of a pneumatic butterfly valve work? Answered

Author:


Pneumatic butterfly valves are particularly widely used as general-purpose valves. Nowadays, many chemical industries, papermaking, coal mines, petroleum, and medical industries will use valves, especially pneumatic valves, and the number used is relatively large. It is a pneumatic butterfly valve that is used in many industries. Pneumatic pipelines are very common! Especially the use of low-pressure medium pipe diameters is increasing, and the larger the pipe diameters of other valves, the more economical they are.

Especially the use of low-pressure medium pipe diameters is increasing, and the larger the pipe diameters of other valves, the more economical they are.

  The reason why pneumatic butterfly valves are so widely used is because of their simple structure, easy maintenance, and fast switching speed, which can not only improve work efficiency but also reduce maintenance time. According to customer requirements, sealing rings and parts of different materials are selected to suit different media and working conditions, so that the pneumatic butterfly valve can achieve great results.

 

  Working principle of pneumatic butterfly valve:

  The pneumatic butterfly valve uses compressed air as the power source to drive the valve stem to control the shaft rotation of the disc. The initial position of the valve is based on actual needs. In the initial position, when the valve rotates 90°, the last movement (from top to bottom, or from close to open) , and for another action (from close to open, or from top to bottom).

  The execution speed of pneumatic butterfly valve is relatively fast, it is not easily damaged during operation, and does not require workers to do it. It can not only be used to cut off the valve, but also assemble a valve positioner to control the pipeline function of the medium. Pneumatic butterfly valve actuators are divided into single-acting and double-acting types. The double-acting type opens the ventilation door and closes the ventilation door! The single-acting spring realizes the reset function and can automatically close or open in the event of air or power failure, with a higher safety factor. high!
