CF type single flange transmission joint is composed of body, sealing ring, gland and short pipe flange components. It is suitable for welding with pipeline while connecting with flange. Installation is to adjust the installation length between the two ends of the product and the pipeline or flange. After installation and welding, tighten the gland bolts diagonally and evenly at one time to form one, with a certain displacement, so that it can be adjusted according to the site size during installation and maintenance. During operation, the axial thrust can be transmitted to the whole pipeline.
The joint is also called electric ball valve, flexible electric ball valve, electric ball valve of valve, shock absorber, valve shock absorber, valve expansion joint, etc. Mainly JGD type and KXT type. This product is a tubular valve part composed of inner and outer rubber, cord layer and steel ring, which is vulcanized at high temperature and high pressure and then loosely combined with metal flange or parallel joint. This product makes use of the advantages of the valve such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance to reduce vibration and noise, and can compensate for thermal expansion and cold contraction caused by temperature changes. It is widely used in various pipeline systems. The electric ball valve is generally composed of an inner rubber layer, a fabric reinforcement layer (the reinforcement layer has multiple layers of rubber scraped nylon cord fabric), a middle rubber layer, an outer rubber layer, an end reinforced metal ring or a steel ring, which is formed by vulcanization at high temperature and pressure, and loosely combined with a metal flange or a 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. Raw rubber is elastic and lacks the necessary plasticity during processing, so it is not easy to process. In order to improve its plasticity, the raw rubber should be plasticated, so that the mixing agent can be easily evenly dispersed in the raw rubber. At the same time, it helps to improve the permeability of the rubber material into the fiber fabric and the molding fluidity during the calendaring and molding processes. The process of degrading long chain molecules of raw rubber to form plasticity is called plasticizing.
