Various displacement problems occurred in the long-term operation of the electric butterfly valve in the waterworks: the double flange electric butterfly valve products are mainly used in the pipeline engineering of the waterworks. The use of the double flange electric butterfly valve can well protect the safe operation of the valve. During the operation period, it can effectively protect the safe operation of the pipeline, especially the large-diameter long-distance pipeline, without any leakage. Various displacement problems and ground subsidence problems occurred in the long-term operation of long-distance pipelines can also be solved by using electric butterfly valves.
Double flange electric butterfly valve is mainly used for loose connection of pump, valve and other accessories. The double flange loose sleeve electric butterfly valve is composed of loose sleeve expansion joint, short pipe flange, rubber screw and other components, which can transmit the pressure thrust (blind plate force) of the connected parts and compensate the pipeline error, and cannot absorb the axial displacement. It is important for loose sleeve connection of pump, valve, pipeline and other accessories
