Pneumatic ball valve can also be called flexible pneumatic ball valve, pneumatic ball valve, pneumatic ball valve, flexible pneumatic ball valve, valve expansion joint, pneumatic ball valve, shock absorber, etc. It is a pipe connector with high elasticity, high air tightness, medium resistance and weather resistance.
The pneumatic ball valve is generally composed of inner rubber layer, fabric reinforcement layer (reinforcement layer has multi-layer rubber scraped nylon cord fabric), middle rubber layer, outer rubber layer, end reinforced metal ring or steel wire ring, which is formed by high temperature and high pressure vulcanization and loosely combined with metal flange or parallel joint. This product makes use of the advantages of the valve, such as high elasticity, high air permeability, medium resistance, weather resistance and radiation resistance, which can reduce the vibration and noise of the pipeline and compensate for the expansion and contraction caused by temperature changes. 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, abrasion resistance, oil resistance, etc. Casing expansion joint is composed of inner and outer casing which 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.
