Stainless steel electric wafer hard seal butterfly valve pneumatic valve D973H - 16 p images

Stainless steel electric wafer hard seal butterfly valve pneumatic valve' D973H - 16页】 Using precision of the elastic sealing ring and triple eccentric metal hard seal structure, multi-level is widely used in medium temperature & le; 425 ℃ of metallurgy, electric power, petrochemical industry, water supply and drainage, and municipal construction and other industrial pipelines, used to adjust flow cutoff and body. The pneumatic valve adopts the three eccentric structure, pneumatic valve seat and disc plate sealing surface are made of different hardness and stainless steel has good corrosion resistance, long service life, all have two-way sealing function, products comply with GB/T13927 - 92 pneumatic valve pressure test standard. Butterfly pneumatic valve in operation work, reduce the torque force, achieve energy saving, energy saving function. The reliability of the bonding resistance loss.



stainless steel electric wafer hard seal butterfly valve pneumatic valve features:



1, the pneumatic valve adopts triple eccentric sealing structure, pneumatic valve seat and disc almost no wear and tear, with the view of the tight sealing function.

2, selection of sealing ring made of stainless steel, has the dual advantages of metal hard seal and elastic sealing, no matter in the case of low and high temperature, has good sealing performance, corrosion resistance, long service life, etc.

4, large size butterfly plate adopts the structure supporting structure, high strength, large flow area, small flow resistance.

5, the pneumatic valve has two-way sealing function, installation is not restricted by medium flow direction, and is not affected by spatial location, can be installed in any direction.

6, driving device can transfer ( Rotate it 90 & deg; Or 180 & deg; ） Installation, making it easy for users to use.




stainless steel electric wafer hard seal butterfly valve pneumatic valve principle:


stainless steel electric wafer hard seal butterfly valve pneumatic valve when the pneumatic valve opens, the butterfly plate in close touch with the pneumatic valve seat, the use of eccentric butterfly plate quickly out of the pneumatic valve seat reduces the seal wear, friction torque is small, open and flexible. Eccentric cone, make the pneumatic valve is in open or closed when the butterfly plate can pass pneumatic valve seat inner hole, realize the contact seal. In addition, the rotation of the cone disc rotating radius radius is greater than the seal contact position, so the disc will appear when the pneumatic valve close off more and more tightly to realize self-locking, prevent a butterfly plate.
