The application of rubber joints can reduce vibration and noise, and can also play a compensating role for thermal expansion caused by temperature changes. It is widely used in various pipeline fragments. It is widely used in a variety of pipeline fragments, such as the continuity of pumps and gates, fire-fighting equipment, pipelines with large vibrations, and pipelines with frequent changes of heat and cold. Because rubber joints have a very good operating sensitivity, they can absorb the pipeline and move in the direction of the working pressure, so that a large part of the working pressure is evacuated by the angle of fire, which is one of the factors of the pressure resistance of rubber joints.
