Screw thread electric butterfly valve, also known as rubber flexible joint, electric butterfly valve, shock absorber, pipe shock absorber, electric butterfly valve, soft connector, etc., is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance.
Features of threaded electric butterfly valve: 1. Small size, light weight, good elasticity, easy installation and maintenance. 2. During installation, it can produce horizontal, axial and angular displacement, which is not limited by the pipeline non centering and flange non parallelism. 3. It can reduce the structural transmission noise and has strong vibration absorption capacity. 4. The internal seamless high-pressure electric butterfly valve can effectively prevent corrosive media from eroding the inner wall of the double ball electric butterfly valve in the high-temperature, acid and alkali resistant and oil resistant pipeline, and improve the service life. Scope of application: It is widely used in basic projects such as chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, water heating, fire protection, electricity, etc. For example, the connection with pumps and valves, pipelines with large vibration, pipelines with frequent changes in cold and heat, etc. Because it can 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. It is most commonly used for water, oil, air, etc. Fan panel unit is the best product for pipe inlet and outlet connection.
Installation method: 1. This product is used for high-rise water supply, and the pipeline must have fixed support or fixed bracket, otherwise the product should be installed with anti pull off device. The force for fixing the support or bracket must be greater than the axial force, otherwise anti pull off device should also be installed. 2. The working pressure selected according to the pipeline is: 0.25MPa, 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa, 4.0MPa; 3. The threaded electric butterfly valve is a kind of rubber connector. It is a hollow rubber product used for flexible connection between metal pipes. 4. According to the connection mode, it can be divided into loose flange type, fixed flange type and threaded type; According to the structure, it can be divided into five types: single sphere, double sphere, reducer, curved sphere and wind pressure coil. Tubular rubber parts are composed of inner and outer rubber layers, cloth layers and steel wire rings, which are formed by vulcanization and then loosely combined with metal flanges or parallel joints.
