Description

Technical Field

[0001] This utility model relates to the field of plastic water pipe technology, specifically a heat-resistant and tear-resistant plastic water pipe. Background Technology

[0002] PVC water pipes are plastic pipes made primarily of polyvinyl chloride and are widely used in water supply and drainage systems in construction, municipal, and agricultural fields.

[0003] Chinese Patent CN220540513U discloses a heat-resistant and tear-resistant plastic water pipe, relating to the field of plastic water pipe technology. It includes a first pipe body and a second pipe body, a connector, one end of the first pipe body being connected to the second pipe body, wherein one end of the second pipe body is screwed to the inner wall of the connector, and a fixing member screwed to the surface of the second pipe body. The fixing member is used to tighten the seal between the first pipe body and the connector. This utility model, through the setting of the fixing member and connector, allows the water pipe to be fixed in use by screwing, similar to the connection method used in most water pipes on the market. However, unlike most water pipes on the market, this water pipe uses a connector to achieve stability during the connection process. Furthermore, during tightening, it can prevent the water pipe from expanding due to hot water, thus avoiding tearing at the connection. The water pipe has a hollow, discontinuous cavity, which can reduce heat conduction and reduce the heat on the surface of the water pipe. It has strong practicality, good commercial value, and is suitable for promotion.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: traditional plastic water pipes are prone to deformation when used in high-temperature water circulation for a long time, and are prone to brittleness and tearing when used in extreme temperatures, which reduces their service life, lowers their safety, and can lead to significant losses. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a heat-resistant and tear-resistant plastic water pipe.

[0006] The technical solution of this utility model is as follows: A heat-resistant and tear-resistant plastic water pipe includes a pipe body, which is provided in multiple sets. The pipe body is composed of an inner layer, a middle layer, and an outer layer. The middle layer is located outside the inner layer, and the outer layer is located outside the middle layer. A first threaded part is located on the outer circumferential surface of one end of the pipe body. A second threaded part is located on the inner circumferential surface of the other end of the pipe body. A connecting mechanism is provided in multiple sets. The connecting mechanism is detachably installed between two sets of pipe bodies. The connecting mechanism is composed of an annular seat, a first support pipe and a second support pipe symmetrically installed on both sides of the annular seat, and a connecting seat that rotatably connects to the annular seat. The outer circumferential surface of the second support pipe is provided with a third threaded part that connects to the second threaded part. The first support pipe is inserted into the inner wall of the pipe body. The inner circumferential surface of the connecting seat is provided with a fourth threaded part that connects to the first threaded part. A second sealing ring and a first sealing ring are respectively sleeved on both sides of the annular seat and on the first and second support pipes. The pipe body is in contact with the second sealing ring or the first sealing ring.

[0007] Preferably, the inner layer is a heat-resistant modified PP layer.

[0008] Preferably, the intermediate layer is composed of a thermoplastic polyurethane layer and a glass fiber mesh.

[0009] Preferably, the outer layer is an ASA protective layer modified with a UV stabilizer.

[0010] Preferably, the annular seat has an annular groove, and the connecting seat is rotatably connected to the annular groove; the inner wall of the connecting seat has a relief groove, the inner diameter of which is larger than the outer diameter of the second sealing ring.

[0011] Preferably, the outer circumferential surface of the tube is uniformly provided with reinforcing ribs, which are spiral in shape.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This utility model improves the overall heat resistance and tear resistance by setting the internal components of the pipe body and the reinforcing ribs; multiple sets of pipe bodies can be quickly connected and spliced ​​by multiple sets of connecting mechanisms, and the connecting mechanisms can also improve the strength of the connection between adjacent sets of pipe bodies. Furthermore, dividing the entire plastic water pipe into multiple sets of pipe bodies can improve the strength of each section of pipe body, thereby improving the overall tear resistance, extending the service life, and improving the safety of use.
