DF flexible valve electric ball valve first-line brand guarantee BF type single flange limit expansion joint is composed of loose sleeve expansion joint, limit stub pipe and other components.
It can prevent the leakage or damage of the compensation joint caused by excessive displacement of the pipeline. It is mainly used for loose sleeve connection of the pipeline to absorb axial displacement and bear pressure thrust within the allowable displacement range. It is suitable for welding with the pipeline while connecting with the flange. During installation, adjust the installation length of both ends of the product and the pipeline or flange, and tighten the gland bolts diagonally and evenly, Then adjust the limit nut, so that the pipeline can be freely expanded within the expansion amount, lock the expansion amount, and ensure the safe operation of the pipeline. Electric ball valve is also called valve electric ball valve, flexible electric ball valve, flexible electric ball valve, valve shock absorber, etc.
The product is mainly composed of tubular valve parts composed of inner and outer rubber layers, cord layers and steel wire rings, which are vulcanized at high temperature and high pressure and then combined with metal flange loose sleeves. It is widely used in fire protection, chemical industry, pump valve and other pipeline systems, playing the role of earthquake resistance and noise reduction, and absorbing the displacement generated during pipeline operation.
