Integrating the mechanical scalability of the metal expansion device and the multiple displacement functions of the flexible electric ball valve, it can not only freely expand and contract mechanically during installation, disassembly and maintenance, but also compensate for the linear expansion and contraction of the pipeline due to temperature changes during operation, and compensate for the different centrality of the pipeline due to ground settlement and the angular displacement of the earth caused by other reasons, At the same time, it can also transmit vibration and noise. It is a multi-functional pipeline pneumatic valve.
Dongfeng Valve Pneumatic Valve Instruction The fast step is not to leap, but to continue; Slow pace is not slow, but wandering; A good road is not a road, but a broad one; The dangerous road is not a steep slope, but a trap; Great happiness is not to get, but to have; Good wealth is not money, but health; Great blessings are not for the future, but for the present. 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. Electric ball valve is a hollow valve product used for flexible connection between metal pipes. Electric ball valve is also called valve pipe electric ball valve, flexible electric ball valve, valve electric ball valve, flexible electric ball valve, high pressure electric ball valve, valve shock absorber, etc. It is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance.
