There are many  production of rubber joint function classification inDomestic hydropower equipment manufacturers.Here we are to understand the characteristics of large diameter double sphere rubber joint and connection method.

Large diameter double sphere rubber joint connection method are: threaded connection, flange connection, the clamp connection.

Large diameter double sphere material: rubber joint ball by inside rubber, reinforced layer, a rubber of rubber compound.Depending on the medium, the use of rubber material is also different.There are natural rubber, butylbenzene rubber, butyl rubber, nitrile rubber, etc.With heat, acid, alkali, corrosion resistant, oil resistant, etc.

Large diameter double sphere rubber joint installation method:

1, double sphere rubber joint installed, ultra displacement limit installation shall be strictly prohibited.

2, installation bolt to symmetry, step voltage tightened, in case of partial disclosure.

3.More than 3, 1.6 MPa pressure, installation bolt to elastic pressure pad, prevent bolt looseness at work.

4, vertical installed on both ends of the joint pipe should be vertical bearing support, should be taken to prevent pulled off device, prevent work pressure pulled off.

5, double sphere rubber joint transportation, loading and unloading, sharp instruments are forbidden to cut surface sealing surface.
