Description

Flexible rubber joint Technical Field The utility model relates to the technical field of pipeline joints, in particular to a flexible rubber joint. Background The flexible rubber joint is also called as shock-absorbing throat, soft joint, soft rubber connection, pipeline shock absorber, etc. and is mainly used for solving the problems of oral deviation, axial expansion and different concentricity of various pipelines, and is generally used for civil building water supply and drainage engineering, pipeline bearing of fire-fighting pipe network pump house unit, sewage treatment pipeline connection, high-pressure gas-liquid chemical medium transportation, petroleum, ships, etc. The rubber joint is a common rubber joint for the pipeline fittings in the current world, and has the advantages of reduced pipeline noise, good sealing performance, light weight, convenient installation and maintenance and long service life. The conventional flexible rubber joint mainly comprises a joint body and slotted flanges sleeved at two ends of the joint body respectively, wherein the end part of the joint body is provided with a flange connecting part, and the flange connecting part and the slotted flanges are not sealed, so that the problem of liquid leakage is easy to generate. Disclosure of utility model The present utility model is directed to a flexible rubber joint, which solves the above-mentioned problems. In order to solve the technical problems, the utility model provides the technical scheme that the flexible rubber connector comprises a connector body and slotted flanges sleeved at two ends of the connector body respectively, wherein the middle part of the connector body between the two slotted flanges is in an outwards-protruding arc-shaped arrangement, the end part of the connector body is integrally provided with a flange connecting part, one end, which is attached to the flange connecting part at one end of the corresponding side, of the slotted flange is provided with an annular connecting groove, one end, which is close to the slotted flange, of the flange connecting part is integrally provided with a connecting ring which is clamped in the annular connecting groove, and the outer wall and the inner wall of the connecting ring are provided with a plurality of convex rings at equal intervals from top to bottom along the circumferential direction of the connecting ring. Further, the cross section of the convex ring is in an arc-shaped arrangement protruding outwards. Further, the cross section of the convex ring is in an inverted triangle shape protruding outwards. Further, the outer wall of the joint body between the two flanges is integrally provided with a reinforcing rib array, and the reinforcing rib array is composed of a plurality of reinforcing rings which are equidistant from top to bottom. Further, the reinforcing rib array further comprises a plurality of reinforcing strips which are arranged at equal intervals along the circumference of the joint body, and the reinforcing rings and the reinforcing strips are integrated and are arranged in a crossing manner. The beneficial effects achieved by the utility model are as follows: 1. The convex ring design on the connecting ring enhances the sealing performance of the joint, and the convex ring is arranged at equal intervals along the inner wall and the outer wall of the connecting ring, so that the friction force of a sealing surface can be increased, liquid or gas leakage is prevented, and good sealing effect can be maintained under different pressures. 2. The plurality of reinforcing rings in the reinforcing rib array effectively disperse the stress and the pressure born by the joint in the working process, and prevent deformation or damage caused by stress concentration, thereby enhancing the bearing capacity of the middle part of the joint body. 3. Through the crossing setting of strengthening ring and reinforcement strip, the joint body has all obtained comprehensive structural reinforcement in axial and circumference for joint body middle part can resist stress and pressure from each direction better, has showing its overall structural strength that has promoted.
