Introduction of the Connection Mode of Butterfly Valve

Linking mode of butterfly valve in clamp butterfly valve, flange butterfly valve, lug butterfly valve and welded butterfly valve 4

1. butterfly valve
The butterfly plate of the clamp butterfly valve is installed in the diameter direction of the pipeline. The valve is fully open.
The clamp butterfly valve has the advantages of simple structure, small volume and light weight. Butterfly valve has elastic seal and metal seal. Elastic sealing valve, sealing ring can be embedded in the valve body or attached to the butterfly plate.
2. Flanged butterfly valve
Flanged butterfly valve is vertical plate structure, the valve stem is integral metal hard seal valve sealing ring is flexible graphite plate and stainless steel composite structure, installed on the valve body, butterfly plate sealing surface surfacing stainless steel. The sealing ring of the soft sealing valve is made of NBR and is installed on the butterfly plate.
3. Lug butterfly valve
4. Welded butterfly valve

Welded butterfly valve is a kind of non-hermetic butterfly valve. It is widely used in pipes with medium temperature less than 300 C and nominal pressure of 0.1Mpa in the production process of building materials, metallurgy, mining and electric power. It is used to connect, open and close or regulate medium volume.
