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. Wuhai EPDM valve electric ball valve has always experienced ups and downs in the life of service supremacy. It will not always rise like the rising sun, nor will it always suffer. Repeated ups and downs are just training for a person.
Therefore, there is no need to be proud of those floating on the top; There is no need to be pessimistic about those who are at the bottom. We must be frank and modest, optimistic and move forward. 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. This product takes advantage of the elasticity, high air tightness, medium resistance, weather resistance and radiation resistance of the valve. It is made of polyester cord fabric with high strength and strong cold and hot stability, which is compounded diagonally with it, and then vulcanized by high-pressure and high-temperature molds. It is widely used in various pipeline systems. Classified according to the external form: single ball electric ball valve, double ball electric ball valve, three ball electric ball valve, concentric reducing electric ball valve, eccentric reducing electric ball valve, clamp type electric ball valve, 90 ° valve elbow, etc. Classification according to the medium used: general (ordinary) electric ball valve, high temperature resistant electric ball valve, acid and alkali resistant electric ball valve, wear-resistant electric ball valve, desulfurization special electric ball valve, etc. Classification according to working pressure: 0.25Mpa, 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.5Mpa, 4.0Mpa.
