Requirements when the end face of the electric ball valve is reinforced with steel wire rings: when the end face of the electric ball valve is reinforced with steel wire rings, the steel wire rings shall be round and located in the same plane in the same year. The difference between electric ball valve and electric ball valve: what is the difference between electric ball valve and electric ball valve? The two seem very similar, but their functions are different. Stainless steel metal hose, also known as metal hose, electric ball valve and stainless steel hose, has good flexibility, temperature resistance, pressure resistance and corrosion resistance, and is suitable for transmission of steam, water, oil and various industrial gases and other media. The electric ball valve ball is composed of a valve pipe with multiple layers of rubber scraped nylon cord fabric and outer rubber layer in the inner rubber layer and reinforcement layer.
The valve materials used vary according to the media, including natural rubber, styrene butadiene rubber, butyl rubber, butyl rubber, EPDM, neoprene rubber, silicon valve, fluorine valve, etc. It has the functions of heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, oil resistance, etc. The electric ball valve plays an important role in the movement, thermal expansion absorption, vibration absorption of the pipeline system. The model length and connection mode of the electric ball valve are based on the user's requirements.
Shijiazhuang single ball electric ball valve manufacturer online quotation Casing expansion joint is composed of inner and outer casing that can make axial relative movement. The stuffing box is used for sealing between the inner and outer casings. Keep the tubes at both ends moving on the same axis during use. The product is mainly composed of sleeve (core tube), shell, sealing material, etc. It is used to compensate for the axial expansion and contraction of the pipe and the axial rotation at any angle. It has the characteristics of small volume and large compensation amount, and is suitable for hot water, steam, grease and other media. The sliding movement of the outer sleeve through the sliding sleeve can compensate for thermal expansion.
