Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, specifically a connection structure for water supply and drainage pipelines in building engineering. Background Technology

[0002] Building water supply and drainage pipes are mainly divided into steel pipes, cast iron pipes, concrete pipes, and plastic pipes, each with different performance characteristics and applicable scenarios. Furthermore, building water supply and drainage pipes typically require connecting structures to link segmented pipe sections.

[0003] Existing building engineering water supply and drainage pipe connection structures are not conducive to adjusting drainage flow, which can affect the connection of water supply and drainage pipes when the water flow is too large, and may even lead to loosening or damage at the connection. It is also difficult to prevent backflow of discharged water, which can not only disrupt the normal operation of the drainage system, but also cause pollution to mosquitoes and flies, spread germs, and damage environmental hygiene if sewage overflows into corridors, streets, indoor areas, etc. It can also cause a chain of harms to environmental hygiene, infrastructure and human health. It is also not easy to double fix, which can lead to insufficient tightness of pipe joints, which can easily increase the risk of loosening or breaking of joints due to pipe displacement or deformation. Furthermore, it is not easy to prevent leakage of discharged water, which can cause sewage leakage to affect the surrounding environment. Therefore, this utility model provides a connection structure for water supply and drainage pipes in building engineering. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a connection structure for water supply and drainage pipes in building engineering, which has the following beneficial effects:

[0016] The water supply and drainage pipe connection structure of this building project is designed with a rotating rod, a self-limiting handwheel, and a circular adjusting plate. During use, the operator rotates the self-limiting handwheel, which in turn rotates the rotating rod and the circular adjusting plate. The flow rate is maximized when the circular adjusting plate is parallel to the inner wall of the connection structure, thus facilitating drainage flow regulation. The structure also incorporates a locking groove, locking protrusions, a rotating column, a sewage baffle, and a spring. During use, the locking protrusions are engaged in the locking grooves, and the rotating column and its surface sewage baffle are installed. The sewage baffle is then opened by the discharged water, allowing the water to flow out through the drain outlet. Subsequently, the sewage baffle returns to its original position due to the spring's elasticity, closing the drain outlet and preventing further discharge. The water recirculation mechanism utilizes a combination of a connecting structure, left fixed half-ring, right fixed half-ring, lock body, lock groove, locking threaded hole one, locking bolt, lock tongue, locking threaded hole two, limit slot one, limit rod, and water supply / drainage pipes. During use, the water supply / drainage pipe is inserted into the connecting structure, allowing the limit rod to be inserted into limit slot one for secure tightening. Then, the lock tongue on the right fixed half-ring is inserted into the lock groove on the lock body of the left fixed half-ring. Finally, the locking bolt is screwed into locking threaded holes one and two in sequence for tightening, thus providing a double-fixing effect and more even support for the pipe connection. The sealing rings, with their tight fit, prevent water leakage during use. Attached Figure Description
