1. Single eccentric flange butterfly valve product introduction

The structure characteristic of single eccentric flange butterfly valve is that the stem axis deviates from the center of butterfly plate, so that the upper and lower ends of butterfly plate no longer become rotary axis, dispersion, and reduce the excessive squeeze between the upper and lower ends of butterfly plate and the valve seat.Is made open-close circular disc and with the valve rod rotation to open and close and adjust the fluid channel of a valve, not only has simple structure, small volume, light weight, low material consumption, small installation size, small and small drive moment, as the anti-corrosion application of synthetic rubber and ptfe, worm wheel flange to improve the performance of the eccentric butterfly valve, and satisfy different working conditions.

2, Single eccentric flange butterfly valve working principle

The structure characteristic of single-eccentric flange butterfly valve is that the stem axis deviates from the center of butterfly plate, so that the upper and lower ends of butterfly plate no longer become rotary axis, dispersion, relieve the excessive extrusion between the upper and lower ends of butterfly plate and the valve seat, and solve the extrusion problem between the butterfly plate and the valve seat of concentric butterfly valve.Seats are synthetic rubber.When closed, the outer circular sealing surface of the butterfly plate squeezes the synthetic rubber seat, causing the seat to produce elastic deformation and forming elastic force for sealing specific pressure to ensure the sealing of the butterfly valve.

3, single eccentric flange butterfly valve product characteristics

1, the unique structure of the valve, flexible operation, labor saving, convenient.

2. The butterfly plate adopts frame structure with high strength, large flow area and small flow resistance.

3. The sealing material is made of stainless steel and silicone oil-resistant rubber, which has a long service life.

4, the valve adopts double eccentric structure, with more closed more tight sealing function, sealing performance is reliable.

5, the overall paint, can effectively prevent corrosion and as long as the replacement of sealing valve seat sealing material, can be used in different media.

6, the rubber seal ring can be located on the valve body, can also be located on the butterfly plate, can be applied to different characteristics of the media, for the user to choose.

7, the valve has a two-way sealing function, installation is not controlled by the flow of the medium, nor by the impact of the space position, can be installed in any direction.
