Description

Technical Field

[0002] Water supply pipeline refers to the water supply pipeline, which uses sanitary polyvinyl chloride (PVC) resin as the main raw material, adds appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., and is extruded by a plastic extruder and injection molded by an injection molding machine. It goes through cooling, curing, shaping, inspection, packaging and other processes to complete the production of pipes and fittings.

[0003] Among the existing Chinese utility models, the publication number CN220647079U discloses a pipeline connection sealing structure, including an inner ring body and a sealing ring sleeved on the outside of the inner ring body. The inner ring body has a C-shaped rotating surface and an opening is arranged on the outer wall. The opening side extends outward to form a disc structure. The sealing ring is sleeved on the outer edge of the disc body, and an elastic abutment sealing is performed through the middle shrink ring arranged in the opening to seal the pipeline, and the inclined surface abutment is used to improve the sealing performance.

[0004] Referring to the above-mentioned pipeline connection sealing structure, the pipeline connection sealing structure uses a middle shrink ring for elastic sealing. This sealing method only relies on the elasticity of the middle shrink ring to seal tightly, and its sealing effect is relatively simple. Once the middle shrink ring is damaged, the sealing of the entire water supply pipeline will be destroyed, and its sealing is relatively poor. Therefore, how to make the water supply pipelines have a better sealing connection effect is an important problem that needs to be solved in the design of a water supply pipeline connection structure with a sealing function.
