Private water supply plant in Shanghai's Songjiang Rubber Joint scale

Rubber joint installation method: 1, rubber joints pipeline construction and installation, must be allowed in a natural state, not artificially make when installing the product produced artificially deformed. This prevents early damage and lead to the weakening effect of the product. 2, if you pump the product designed and installed in the corner of the proximal portion of the outlet or pipe is, and high pressure, high-rise buildings left vacant when using the product, the pipeline must have a fixed support or mounting bracket, fixed support and mounting bracket the force must be greater than the axial force, otherwise the product should install anti-pull-off limit device. 3, rubber flexible joints in the installation shall be such that the ball ends enhancement (inner projection just rope) all Karufalan ring groove, preventing the ball and 法兰拉 pipeline pressure off. When the bolt, bolt first symmetrical (six or four) tightened to ensure the ball on the flange in place. 4, when the rubber joints and pipe flange, pipe flange bolts screw should be toward the end, in order to prevent the arch portion of the thread will be under pressure when the expansion rubber joints Jishang or stabbed, each end of the bolts must be applied symmetrically Pressure tighten all bolts tightness consistent use of place harsh conditions, in addition to increasing the pad, it should also increase spring washers to prevent the nut loose. 5, when the rubber joints used in water (oil) pump outlet close or open condition to stop frequently to reduce the length of the stretched rubber joints and compressed-impact and bring the pump and piping should be two flanges end increase stopper. 6, the installation of large diameter rubber joints, for ease of installation and reduce labor intensity, should make an end flange short pipe section right amount of length, to be rubber joints and short pipe and the other end of the pipe connected later, and then a short tube and their counterparts in the long end of the pipe welding. 7, to facilitate radial deviation due to the short tube welding deformation caused by welding metal objects should be in front with round or other appropriate strength of the temporary pipe flanges welded ends, the rubber joints and the flange connections form a rigid body until after the completion of the short pipe welding, soldering material and then removed so that the rubber joints after installation in a natural state. 8, in the implementation of the temporary metal connectors and flange welded solid, remember to cover up the matter with the weld joints rubber cover, so as not to burn the ball during welding. 9, if the pipeline to be buried in the ground change, please use our plant developed the production of buried protective device.
