Introduction: Shanghai flexible double ball rubber joint is composed of fabric reinforced rubber parts, flat flexible joint, loose metal flange or threaded pipe flange, which is used for vibration isolation, noise reduction and displacement compensation of pipeline. It is a kind of high elasticity, high air tightness, medium resistance and gas resistance

Shanghai flexible double sphere Rubber joint It is a joint composed of fabric reinforced rubber parts and flat flexible joint, loose metal flange or threaded pipe flange, which is used for pipe vibration isolation, noise reduction and displacement compensation.

It is a kind of pipe joint with high elasticity, high air tightness, medium resistance and climate resistance. Concentric diameter, concentric diameter reduction, eccentric diameter reduction. Flexible Double ball rubber joint The structure is divided into: single sphere, double sphere and elbow sphere. Flexible double ball rubber joint can be divided into flange connection, threaded connection and threaded pipe flange connection. The working pressure of flexible double ball rubber joint is divided into five grades: 0.25MPa, 0.6MPa, 1.0MPa, 1.6Mpa and 2.5MPa. Flexible double ball rubber joint features: small volume, light weight, good elasticity, easy installation and maintenance. During installation, it can produce lateral, axial and angular displacement, which is not limited by the pipe not in the center and the flange is not parallel. It can reduce the transmission noise of structure.

  1、 Flexible rubber joint Pipeline construction, need to make it in a natural state, do not artificially in the installation of products produced artificial deformation. When the pipeline medium is acid and alkali resistant, oil resistant, high temperature and other special materials, the joint with a gear higher than the pipeline working pressure should be selected.

2. Flange connecting flexible rubber joint shall be valve flange or flange conforming to GB / t9115.1 (RF).

3. The normal applicable medium of the flexible rubber joint is ordinary water with a temperature of 0-60 ° C. In case of special media such as oil, acid and alkali, high temperature and other corrosive and hard materials, the flexible rubber joint with corresponding special resistance shall be selected, and it is not allowed to be used in series or in general blindly.

4. When the flexible rubber joint is used at the inlet and outlet of the water pump, it should be located at the side of the water spring, and the metal reducing joint should be installed between the water spring and the water spring, and it should be installed at the large diameter source of the variable diameter.

5. When the pipeline displacement is greater than or equal to the compensation of the joint, the number of joints should be increased to parallel the displacement. It is strictly forbidden to adjust the pipeline out of tolerance to make the joint in the state of displacement and deviation, and not to exceed the limit (expansion, displacement, deflection, etc.). See the table below for the specific installation data.
