The metal sealing butterfly working principle of the pneumatic valve

how it works:
worm gear two-way metal seal butterfly pneumatic valve by turning the handwheel by worm gear pair of institutions such as slow, drive the pneumatic valve stem disc ° rotation, within the scope of truncation, connected or adjust the flow rate. Electric two-way metal seal butterfly pneumatic valve by electric actuator driven by gear or directly by the worm gear pneumatic valve stem and disc ° within the scope of the rotation, so as to achieve the purpose of opening and closing. Worm gear drive and electric, pneumatic valve closed or open position in both institutions limit, and has displayed indicating device of butterfly plate opening state.
characteristics:
, this butterfly pneumatic valve structure size short, small volume, light weight, convenient operation.
and the butterfly pneumatic valve adopts half shaft structure, butterfly plate adopt truss structure, high strength, large flow area, small flow resistance, save energy.
and the butterfly pneumatic valve adopts eccentric structure, soft seal butterfly pneumatic valve to realize the butterfly plate in open in an instant, the separation, close contact with the sealing effect and prolong the life span, sealed performance is best.
, selection of the butterfly pneumatic valve sealing surface of stainless steel, with metal sealing and the double advantage of elastic sealing, no matter in the case of low and high temperature, has good sealing performance, corrosion resistance, long service life, etc.
, this butterfly pneumatic valve has two-way sealing function, installation is not restricted by medium flow direction ( If only control one-way medium, ventilation butterfly pneumatic valve installed should be preferred for sealing direction) , also is not affected by spatial location, elastic metal hard seal butterfly pneumatic valve can be installed in any direction.
metal seal butterfly pneumatic valve is my company on the basis of the introduction of foreign advanced technology, after improved, the precision of the elastic sealing ring in contact with the butterfly plate after throwing light, widely used in metallurgy, petrochemical industry, three partial hardness seal butterfly pneumatic valve of air and water supply and drainage and municipal construction and other industries to adjust and intercepting device used in the pipeline.
