Introduction: Supplement flexible rubber flexible joint expertise to avoid problems in use. As we will all know, rubber joint is also called flexible rubber joint and rubber soft joint. The utility model is connected by a ball and a flange, and a tube is composed of an inner surface layer of rubber, a cloth curtain layer and a steel ring

Supplementary flexibilities Rubber flexible joint Expertise to avoid problems in use. Everyone will understand, Rubber joint Also called Flexible rubber joint Flexible joint of rubber parts. It is composed of a ball and a flange, a tubular rubber part composed of an inner surface layer of rubber, a cloth curtain layer and a steel ring, which is vulcanized to form a loose sleeve with a metal flange or a parallel joint. Rubber joint can reduce vibration and noise, and can compensate for thermal expansion and cold contraction caused by temperature change. It is widely used in various pipeline systems. However, no matter how good the quality of the flexible rubber joint is, there will be some defects in the use of the flexible rubber joint in the pipeline
1. Pull off phenomenon. It is mainly caused by excessive pressure when rubber joints are used in pipes with vibration or a certain slope and turning. Suggestion: install anti pull off equipment.
2. Cracking of flexible rubber joint. Main reason: along with the different service life and environment of rubber joint. It is suggested that 1. The inner hole of rubber joint should be reinforced with steel ring. When the inner hole of rubber joint is reinforced with steel ring, the steel ring should be kept in the ring and should be in the same plane in the same year. 2. Let the customer replace the material suitable for the environment.
3. Concave and shrunken. The main reason is that the flexible rubber joint is installed in the water pump, which causes excessive pumping. In other words, if your pump is blocked or your pump pipe is smaller, it will not happen.
During the installation of flexible rubber flexible joint, all reinforcement rings on both sides of the ball (highlighting a part of the inner steel wire rope) must be stuck into the flange groove to avoid pulling off the ball and flange when the pipeline is under pressure. When installing the bolts, first tighten the symmetrical bolts (six or four) to ensure that the ball is on the flange in time. When the flexible rubber joint is connected with the pipe flange, the screw rod of the bolt shall extend to one end of the pipe flange to prevent the external thread from pinching or stabbing a part of the flexible rubber flexible joint when the force is inflated. The bolts at each end must be symmetrically pressurized and tightened to make all the bolts loose and tight. In the places with bad service conditions, in addition to the flat washer, the spring washer should also be lifted, Prevent nuts from loosening.
It is forbidden to exceed the displacement limit when the flexible rubber joint is installed. Pipeline engineering construction and installation, must be in a natural situation, do not need to artificially in the installation of products caused by artificial deformation. In this way, the initial damage of the product and the weakening of the use effect can be avoided. If the design product is installed at the far end of the inlet and outlet of the water pump or the corner of the pipe, and when the product is used in high pressure and high-rise buildings, the pipeline must have fixed support point or fixed bracket, and the support of the fixed support point and fixed bracket must exceed the axial force, otherwise, the product should be installed with anti pulling off limit device.
