Description

Technical Field

[0001] The utility model relates to the technical field of PVC-U drainage pipes, in particular to a PVC-U drainage pipe with high impact strength. Background Art

[0002] PVC-U drainage pipes are made of sanitary polyvinyl chloride (PVC) resin as the main raw material, with appropriate amounts of stabilizers, lubricants, fillers, color enhancers, etc. added, and are extruded by a plastic extruder and injection molded by an injection molding machine. The production of pipes and fittings is completed through processes such as cooling, curing, shaping, inspection, and packaging.

[0003] After searching, the Chinese patent application No. 201822135527.1 discloses a high-pressure and high-elasticity PVC-U drainage pipe, including a body, wherein the body is provided with a PVC-U outer protective layer, a hollow spiral, an inner layer and reinforcing ribs from the outside to the inside in sequence, and the PVC-U outer protective layer is hot-melt connected to the inner layer through the hollow spiral, and the inner layer and the reinforcing ribs are arranged as a whole, and the reinforcing ribs are distributed in the inner layer in a "cross" shape. This utility model patent, through the cooperation between the PVC-U outer protective layer, the inner side and the hollow spiral, under the action of the reinforcing ribs, the surface hardness and tensile strength of the PVC-U outer protective layer are excellent, the safety factor is high, and the aging resistance is good. Compared with cast iron drainage pipes, it has excellent anti-freezing performance and has good noise reduction performance. The spiral silencer pipe reinforcement ribs that can reduce drainage noise can strengthen the longitudinal bearing capacity of the inner layer, so that the body can be used normally when it exceeds its own prestress, and the calcium powder dressing ratio is good. It can rebound and recover after being hit, and has excellent compressive resistance.

[0004] Although the above patent, through the coordination between the PVC-U outer protective layer, the inner side and the hollow spiral, under the action of the reinforcement ribs, the PVC-U outer protective layer has excellent surface hardness and tensile strength, high safety factor, good aging resistance, and excellent anti-freezing performance compared with cast iron drainage pipes, and has good noise reduction performance, the reinforcement ribs of the spiral silencer pipe that can reduce drainage noise can strengthen the longitudinal bearing capacity of the inner layer, so that the body can be used normally when exceeding its own prestress, the calcium powder dressing has a good ratio and can rebound and recover after impact, and has excellent compressive resistance, but in actual use, the pipe in the above patent is not convenient for eliminating the vibration generated by the impact of water flow when in use, which is easy to cause loosening and leakage at the pipe interface, and it is not convenient to adjust and reduce the pressure of the water flow entering the water pipe. The internal pressure of the drainage pipe increases when it is impacted by a large flow of water, which is easy to cause the pipe to rupture and deform, bringing inconvenience to the user.

[0005] Therefore, it is necessary to transform it to effectively reduce the vibration generated when water flows in the pipe, avoid loosening and leakage due to pipe resonance, rectify the water flow entering the pipe, and avoid the pipe being impacted by large-flow water flow, which increases the internal pressure of the pipe and makes it easy to rupture and deform.
