Pneumatic ball valve is generally designed for connecting pipes with smaller diameter, which is convenient and fast. Like other pneumatic ball valves, different valve materials are selected for different media, including natural valves, styrene butadiene environment, butyronitrile, butyl, etc., which have excellent performance in heat resistance, acid resistance, corrosion resistance, etc. Pneumatic ball valves have many other advantages. The utility model has the advantages of convenient installation, easy replacement, high pressure resistance, light weight, etc.
Detailed Description of Dongfeng Valve Pneumatic Ball Valve 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. Pneumatic ball valve is also called valve pneumatic ball valve, flexible pneumatic ball valve, flexible pneumatic 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. Pneumatic ball valve is a hollow valve product used for flexible connection between metal pipes.
Pneumatic ball valve is also called valve pipe pneumatic ball valve, flexible pneumatic ball valve, valve pneumatic ball valve, flexible pneumatic ball valve, high pressure pneumatic 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. According to the external form, it can be classified as: single ball pneumatic ball valve, double ball pneumatic ball valve, three ball pneumatic ball valve, concentric reducing pneumatic ball valve, eccentric reducing pneumatic ball valve, clamp type pneumatic ball valve, 90 ° valve elbow, etc. Classification according to the medium used: general (ordinary) pneumatic ball valve, high-temperature resistant pneumatic ball valve, acid and alkali resistant pneumatic ball valve, wear-resistant pneumatic ball valve, desulfurization dedicated pneumatic ball valve, etc.
