Introduction: Buried rubber flexible joint is also called shock absorber, pipe shock absorber, shock absorber throat, soft joint, etc. The buried rubber flexible joint is a flexible coupling of metal pipe, which is composed of rubber ball reinforced by inner rubber layer, nylon cord fabric and outer rubber layer, and loose metal flange group

Buried type Rubber flexible joint Also known as shock absorber, pipe Shock absorber Shock absorber throat, soft connector, etc. Buried rubber flexible joint is a flexible coupling of metal pipe, which is composed of rubber ball with inner rubber layer, nylon cord fabric reinforcement, outer rubber layer composite and loose metal flange.
It can be widely used in water supply and drainage, circulating water, HVAC, fire protection, papermaking, pharmaceutical, petrochemical, ship, water pump, compressor, fan and other pipeline systems. It is used for transporting compressed air, water, water, water and so on. The special type is used to transport the above medium or oil, concentrated acid and alkali, solid materials above - 30 ℃ ~ 250 ℃.
The cover is made of steel plate or steel plate. All types of flexible joints can be provided with corresponding types of guide rail protection (horizontal, vertical, inclined, transverse). Flexible Rubber joint There is enough space around the buried protection device, which will not affect the displacement performance of the rubber joint, but also make the rubber joint separate from the external filling. It can also make the pipeline slide freely at both ends of the device without any resistance. After the pipeline is installed, the ground is as smooth as before after backfilling and tamping, and the ground is as smooth as before, and the vehicles are running, and the heavy objects or installation equipment are not affected. This configuration is equipped with a certain number of locking bolts for assembly after installation. The installation method is as follows: installation of rubber joint → coating of asphalt inside the protective device → installing the lower 1 / 2 protection device → putting the upper 1 / 2 protection device → tightening the locking bolt (make sure that the rubber joint is in the center of the device during installation) → coating asphalt antirust outside the protection device → backfilling the original soil, tamping the lower part and tamping the upper part → triad soil and cushion layer → Lay the ground (it's good to have a long-term sign at the appropriate position for future inspection and replacement)
Installation method:
1. It is strictly forbidden to install the rubber joint beyond the displacement limit.
2. The installation bolts should be symmetrical, and gradually pressurized and tightened to prevent local leakage.  
For working pressure above 3.1.6mpa, elastic pressure pad shall be provided for installation bolt to prevent bolt loosening during operation.  
4. During vertical installation, both ends of the joint pipe shall be supported by vertical force, and anti pulling device can be adopted to prevent pulling off under working pressure.  
5. The installation position of rubber joint should be far away from heat source and ozone area. It is strictly prohibited to expose to strong radiation light and use, which does not meet the requirements of this product
