Rubber joint function
1. Shock absorption and noise reduction: Rubber joints use their high elasticity and cushioning properties to absorb the pressure shock, vibration and noise of the fluid in the pipeline, thereby reducing the movement and noise of the pipeline, and reducing the risk of rupture and leakage of the pipeline.
2. Compensation displacement: This joint can adapt to the thermal expansion and contraction of the pipeline caused by temperature changes, compensate for the displacement caused by temperature changes, and ensure the stable operation of the pipeline system.
3. Good sealing: The sealing performance of the rubber joint is good, which can prevent the leakage of the medium and ensure the safe operation of the pipeline system.
4. Adapt to a variety of media: According to different media, rubber joints can be made of different rubber materials, such as natural rubber, styrene-butadiene rubber, nitrile rubber, etc., to meet the functional requirements of heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, oil resistance and so on.
5. Wide application: Rubber joints are widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power and other basic projects, suitable for a variety of complex pipeline systems.
6. Easy installation and maintenance: Rubber joints are usually connected by flange or thread, which is relatively simple to install and maintain, which can reduce installation and maintenance costs.
The connection between the rubber soft joint and the pipe
The fixation method is suitable for occasions with low pipeline pressure, low temperature and stable use environment. Tie the rubber soft joint to the pipe through metal clamps or steel wires, and the fixing points are located at both ends of the soft joint, and the clamping force should be uniform to avoid uneven force on the soft joint.
Compression method certain length of metal pipes are installed at both ends of the rubber soft joint, and the metal pipes at both ends of the rubber soft joint are compressed and fixed by welding the angle steel or flange and tightening the flange bolts. This method is suitable for occasions with multiple bends, large vibration of pipes, and large pressure impact.
Clamp method metal clamps are installed at both ends of the rubber soft joints to connect the pipes through the clamps that are too tight or too loose. The clamp can be elastic or inelastic, depending on the actual situation. This method is suitable for occasions with low pressure, high temperature and low vibration of pipes.
Flange connection metal flanges connected with direct flanges of the pipe are installed at both ends of the rubber soft joints, and the two flanges are connected together by bolts. This method is suitable for pipeline systems with strict working conditions, such as high temperature, high pressure, corrosion and other environments.
