Liwei soft rubber joints when used in the pump import and export, springs should be located on one side, between the springs and metal adjustable joints should be installed and mounted on large diameter adjustable source. When the pipe displacement is greater than the maximum compensation amount equal to the joint, should increase the number of joints to parallel displacement, non-tolerance in order to adjust the pipe, the joint state in flexural displacement and deviation limit, but can not exceed the limits (stretching, displacement, deflection, etc.).

Senior water supply or vacant water supply pipes should be fixed in the hanger bracket or anchor shelves and does not allow the joint to bear its own weight and axial force pipeline, otherwise joints should be equipped with anti-pull-off device (which must be greater than the pipe axial tolerance force).

When installing rubber joints, screw bolts should stretch the outer joint, every bolt flange face by diagonal compression method repeatedly tightened evenly to prevent pressure side. Threaded joints should use standard wrench uniform force tighten, so do not use afterburner afterburner union stalk silk slip, slip ribs and broken, but also to regular inspection, so as not to cause loosening off the plate or seepage.
Soft rubber joints under pressure in the initial (eg: installation pressure test, etc.) after long-term disabled or enabled again before the bolts should be tightened again pressurized into operation. Use or storage of soft rubber joints, should avoid high temperature, ozone, oil and acid-base environment.

Use outdoors or in the sunny shade wind pipe rack should build prohibited Sai storm, rain, wind cloud. Joint surface painting and winding insulation materials is strictly prohibited. Due to the existence of the problem of aging of rubber products, should be checked and replaced.

When the rubber joints pipeline construction, must be allowed in a natural state, not artificially generated during the installation of artificial deformation of the product, when the pipe medium acid, oil, heat and other special materials should be chosen higher than the working pressure of a pipeline stall linker. Connection flange rubber joints should be in line with the valve flange or GB / T9115.1 (RF) flanges. Can be curved around the rubber joints normally applicable medium temperature 0-60 ° C in ordinary water, special media such as: lower oil, pH, temperature and other corrosive and hard texture of the case, should be used in relatively resistant materials deserve special rubber joints not blindly use string or universal.
