Butterfly valve working animation, working principle

The butterfly valve is a kind of butterfly valve that is opened and closed according to the rotation of the valve stem and the rotation of the disc plate. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, mainly by rotating the disc 90° to control the flow. , When the disc plate reaches 90°, the butterfly valve is in a fully open state, and the angle of the disc plate can be changed to adjust the flow of the medium, which is generally installed in the diameter direction of the pipeline.

Butterfly valve and valve stem have no locking ability. In order to effectively adjust the flow, a worm gear reducer needs to be installed. The butterfly valve with worm gear reducer not only makes the butterfly valve have self-locking ability, but also changes the operating performance of the butterfly valve and adjusts the medium flow more accurately.

Butterfly valve working principle

  1. When the butterfly valve is fully opened, it has a small flow resistance. When the opening is between about 15° and 70°, sensitive flow control can be performed, so the application of butterfly valves is very common in the field of large-diameter adjustment. Since the movement of the butterfly valve plate is wiping, most butterfly valves can be used for media with suspended solid particles. Depending on the strength of the seal, it can also be used for powdered and granular media.
  2. Butterfly valve is suitable for flow regulation. Because the pressure loss of the butterfly valve in the pipe is relatively large, which is about three times that of the gate valve, when selecting the butterfly valve, the influence of the pressure loss of the pipeline system should be fully considered, and the strength of the butterfly plate to withstand the pressure of the pipeline medium should also be considered when it is closed. . In addition, the operating temperature limitations of the elastomeric seat material at elevated temperatures must also be considered.
  3. The structure length and overall height of the butterfly valve are small, the opening and closing speed is fast, and it has good fluid control characteristics. The structure principle of butterfly valve is more suitable for making large diameter butterfly valve. When the butterfly valve is required to control the flow, it is more important to correctly select the specification and type of the butterfly valve so that it can work properly and effectively.
