Description
Technical Field
[0001] The utility model relates to the technical field of pipeline sealing, in particular to a reinforced anti-leakage sealing structure. Background Art
[0002] The pipe connector is a device that is made of stainless steel and rubber to achieve the function of sealing and pressure bearing. It has a very compact structure. No treatment is required on the pipe ends during construction. Just put the connector on the two pipe ends to be connected and tighten the side bolts. The teeth will bite the surface of the pipe ends to achieve the limit fixation, and the sealing sleeve will be tightly attached to the pipe to achieve a locked state of sealing and firm connection.
[0003] The existing enhanced anti-leakage sealing structure can refer to the Chinese utility model patent with authorization announcement number CN216520078U, which discloses a pipeline connector 1 and a pipeline connector 2 with enhanced sealing and anti-leakage, "including an insert 1, a step 1 is provided in the insert 1; an injection molded part 1 is sleeved on the outside of the insert 1, and a receiving groove that cooperates with the step 1 is provided in the injection molded part 1; a seal is located between the insert 1 and the injection molded part 1, and one end of the seal cooperates with one end of the injection molded part 1. Pipe connector 2 includes: an insert 2 threadedly connected to the insert 1; an injection molded part 2 sleeved on the outside of the insert 2; wherein, one end of the seal away from the injection molded part 1 cooperates with both the insert 2 and the injection molded part 2. In view of the sealing performance of the joint between plastic and metal in the production of pipeline connectors and solving the problem of complex and easy leakage of raw tape construction during installation, the technical effect of the utility model is that it has better sealing performance and more convenient construction"
[0004] When the above device is in use, the existing device uses the pipe connector to compress the seal to prevent water from seeping out from the connection between the seal and the insert one, thereby preventing water seepage from the source, so that the pipe connector one does not need to use raw tape when cooperating with other pipe connectors, and can also achieve a good sealing effect, and the seal is easy to disassemble and assemble with the injection molded part one. However, in the case that the independent pipe connection is loose, it is difficult to avoid water from seeping out from the connection between the seal and the insert one. Therefore, a layer of rubber sealing ring is added outside the independent pipe connection, and the anti-leakage effect will be better. The added rubber sealing ring needs to avoid falling off and damage. Therefore, a reinforced anti-leakage sealing structure that solves the above problems is needed. Utility Model Content
