Double-ball rubber compensator is also called rubber joint, rubber soft joint, rubber soft joint, rubber retractor, rubber expansion joint, pipeline shock absorber, shock absorber and so on. The product is a flexible connector for metal pipes, which is composed of an inner rubber layer, a nylon cord fabric, a rubber ball composited with an outer rubber layer and a loose metal flange. It has the characteristics of high pressure resistance, good flexibility, large displacement, balanced pipeline deviation, absorption of vibration, low noise reduction and convenient installation. It is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power and other basic projects.
According to different materials, it can be made into various varieties such as acid, alkali, corrosion, oil and heat, and it can adapt to various media and environment.
1. This product can greatly reduce the vibration and noise of the pipeline system, and can fundamentally solve the problems of interface displacement, axial expansion and different degrees of heart of various pipelines.
2. According to different materials, it can be made into various varieties such as acid, alkali, corrosion, oil and heat, and it can adapt to various media and environment.
3. The material is polar rubber, good in sealing, light in weight, convenient in installation and maintenance, and long in service life, but avoid contact with sharp metal instruments to avoid puncturing the sphere.
4. If the overhead is used, it can be equipped with a flexible bracket. When installing, the bolt should be tightened diagonally.
5. If the line pressure is too high, apply the limit bolts to connect the flanges at both ends.
Double sphere rubber compensator purchase points:
1. When selecting a suitable double-ball rubber compensator, the first factor to consider is the size of the diameter. If the diameter of the double-ball rubber compensator is not suitable for the pipeline transportation system, other factors are not considered. It is necessary.
2, the customer needs to consider the pressure of the medium transported by the double sphere rubber compensator on the pipe wall, as well as frequency, strength and other factors.
3. Whether the medium transported by the pipeline has corrosion and high frictional strength to distinguish the material of the rubber compensator sphere.
4. Select according to the ambient temperature when the hose is working. At high temperatures, the operating pressure temperature correction factor at the high temperature of the metal hose shall be determined to determine the pressure after the temperature correction to determine the correct pressure rating.
5. According to the state of the double sphere rubber compensator, refer to the correct use and installation method of the double sphere rubber compensator and the optimal length of the pipeline during settlement compensation.
