Installation and use of double sphere rubber joints.
Installation and use of double sphere rubber joints.
1. Double spherical rubber joints are selected according to the working pressure of the pipeline, the connection mode, the medium and the compensation amount, and their quantity is selected according to the noise reduction and displacement requirements. 2. The installation pipeline generates instantaneous pressure and is greater than the working pressure when the joint should be selected one gear higher than the working pressure. 3. When the pipeline medium is acid and alkali, oil, high temperature and other special materials, the joint with one gear higher than the working pressure of the pipeline should be used. 4. Normal applicable media is the temperature of 0-60 ℃ ordinary water, special media such as: oil, acid and alkali, high temperature and other corrosive and hard texture of the case, the corresponding special resistant materials should be selected Rubber flexible joints, not blindly string or general. 5. When the displacement of the pipeline is greater than the compensation amount of the rubber soft connection, the number of joints should be increased to parallel displacement, it is strictly forbidden to adjust the pipeline over the difference, so that the joint in the state of disturbance displacement and deviation, not to exceed the limits (expansion, displacement, deflection, etc.). 6. For high-rise water supply or suspended water supply, the pipe should be fixed on a hanger, bracket or anchor, and the joint should not be allowed to bear the pipe's own weight and axial force, otherwise the joint should be equipped with an anti-pull-off device (its bearing force is greater than the pipe axial force).
