Three eccentric multi layer worm gear flange type butterfly valve
Features and usage:
Three biased multi-level metals hard seal butterfly valve series,is the long life which the our company newly develops,the energy conservation butterfly valve.The product conforms to national standard JB/T8527-97(metal hardly to seal reed valve),GB/T13927-2008(general valve pressure test)the standard and the valve other correlation standards stipulations,unifies the domestic and foreign advanced technologies,uses the three dimensional eccentric principle design,the seal packing collar uses hardy softly seals the concurrently multi-level structure,is suitable to the medium temperature≤600℃metallurgy,the electric power,the petroleum chemical industry,the air,teh coal gas,as well as for medium pipeline on and so on the draining water makes the adjustment current capacity and the interruption fluid,the sealing property is rellable,is the general reed valve pressure,center high temperature domain extending to the cemter with the development.
In this structure foundation,may use the teflon to substitute the multi-level seal packing collar,forms the new generation of three biased four fluorine seals reed valves,widespread application in temperature≤200℃ corrosive medium environment.
Features:
1.The butterfly board seal packing collar for hard is soft double-decked,has the hard soft seal dual seal merit,regardless of in the low temperature or under the high temperature operating mode,has the fine sealing property.
2.Uses three eccentric structures,the valve seat and the butterfly board nearly no friction,has the pass tighter sealing property,achieved zero divulges.
3.Opens shuts the moment of force slightly,the operation nimble,the vigor energy conservation,the service life is longer.
4.Thermostable,bears the high pressure,the air-corrosive applicable scope is broad.
5.the new generation of three biased four fluorine seals reed valve concurrently has had three biased seals structure and the soft seal merit,the sealing property more realiable,the applicable scope broader,the service life is longer.
6.electrically operated,the pneumatics uses the domestic and foreign famous products,the performance is more reliable (may assign by user).
