What principle should follow in the installation of flexible rubber joint.

Adjustable in a flexible rubber joint is a kind of high elasticity, high air tightness, medium resistance and weatherability of pipeline joints, also known as rubber flexible joint, in a flexible rubber joint, etc., the product USES the rubber elasticity, high air tightness, medium resistance, weather resistance and radiation resistance, etc, with the high density of internal cause, can bear high pressure, good effect of elastic deformation, etc.When the product in the installation must follow the following principles, to ensure the safety of the installation:
1, must according to the working pressure pipeline, connecting method, medium, and compensation amount to choose the appropriate model, the number of selected according to the displacement of noise reduction requirement.
2, when the pipeline instantaneous pressure is greater than the pressure of work and should be chosen when higher than working pressure of a gear coupling.(such as: pipe to start the instantaneous pressure > 1.0 MPa, elected labor as a sub 1.6 MPa. Instantaneous pressure > 1.6 MPa, 2.5 MPa should choose joint).
3, when the pipeline medium for acid and alkali, oil, high temperature, and other special materials should be chosen when the above pipeline working pressure of a gear coupling.
4, connect the rubber joint flange should be the valve flange or is in line with GB/T9115.1 (RF) of the flange.
5, normal applicable medium can be curved around the rubber joint, it is ordinary water temperature from 0 to 60 ℃, such as special medium: oil, acid and alkali, high temperature and corrosion resistance and other hard cases, should choose the corresponding materials resistant rubber joints, do not blindly string or gm.
