What is the role of the rubber joint ?
1.Shock absorption and noise reduction :Rubber joint has good elasticity and buffer performance, can effectively absorb the vibration and shock in the pipeline, reduce the noise and vibration of the pipeline system, so as to protect the pump, valve and other equipment from damage.
2.Prevent media leakage :The rubber joint has good sealing performance, which can effectively prevent the media leakage in the pipeline and avoid environmental pollution and safety accidents.
3.Protective equipment :By reducing the vibration and noise of the pipeline system, rubber joints can protect pumps, valves and other equipment from damage and extend their service life.
4.Easy installation :The installation and maintenance of the rubber joint is relatively simple, and it can be connected with the pipeline by means of flange or wire buckle to meet different installation requirements.
5.Damping effect :In natural disasters such as earthquakes, rubber joints can effectively reduce the vibration and damage of pipelines, and ensure the safety of industrial production and people's lives and property.
Installation method of rubber joint
1. When installing rubber joints, it is forbidden to install them beyond the displacement limit.
2. The mounting bolts should be symmetrical, gradually pressurized and tightened to prevent local leakage.
3. 1.6MPa or more working pressure, install bolts with elastic pressure pad to prevent bolts from loosening during work.
4. The two ends of the joint pipe should be supported by vertical forces when installed vertically, and the anti-pulling device can be adopted to prevent the working pressure from pulling off.
5. The installation part of the rubber joint should be away from heat sources. Ozone area. Strong radiation exposure and use of media that do not meet the requirements of this product are strictly prohibited.
6. Rubber joints are strictly prohibited from cutting the surface and sealing surface with sharp instruments during transportation and loading.
