Butterfly valve works you know?

Butterfly valve is based on the rotation of the stem at the same time drive the disc to turn on and off a valve in the butterfly valve body cylindrical channel, disc-shaped butterfly plate around the axis of rotation, mainly rotating disk 90 ° to do flow control , When the disc reaches 90 ° when the valve is fully open, and can change the angle of the disc to adjust the media flow, generally installed in the diameter of the pipeline. Butterfly valve and stem itself is not locked capacity, in order to effectively adjust the flow required to install the worm reducer, the installation of worm gear reducer butterfly valve not only has self-locking ability, but also to change the operational performance of the butterfly valve and more accurate adjustment of medium flow The

1, butterfly valve in fully open, with a smaller flow resistance. When open between about 15 ° ~ 70 °, and can be sensitive to flow control, so in the field of large diameter adjustment, butterfly valve application is very common. As the butterfly butterfly plate movement with a wipe, so most of the butterfly valve can be used with suspended solids particles of the media. Depending on the strength of the seal, it can also be used in powder and granular media.

2. Butterfly valve is suitable for flow regulation. As the butterfly valve in the tube of the pressure loss is relatively large, about three times the gate valve, so the choice of butterfly valve, the pipeline system should be fully considered the impact of pressure loss, but also consider the closure of the butterfly board to withstand the strength of the medium pressure The In addition, the operating temperature of the elastomeric seat material at high temperatures must also be taken into account.

3. Butterfly valve structure length and overall height is small, open and close faster, and has good fluid control characteristics. Butterfly valve structure of the most suitable for the production of large diameter valves. When the butterfly valve is required to control the flow of use, the most important thing is to correctly select the butterfly valve specifications and types, so that it can work properly and effectively.
