Description

Technical Field

[0001] The utility model belongs to the technical field of polyethylene pipes and relates to a polyethylene inner pipe with detection points. Background Art

[0002] Polyethylene pipes, commonly known as plastic pipes, are mainly divided into PE pipes, PP-R pipes, and UPVC pipes. Polyethylene pipes have good impact resistance, corrosion resistance, wear resistance, etc., and also have the effect of resisting stress cracking. It is one of the most widely used pipe bodies at present; Patent No. CN202021988101.1 discloses a polyethylene pipe hot-melt liner pipe device, comprising an outer pipe and an inner pipe, the inner pipe is located inside the outer pipe, and the two ends of the outer pipe are respectively engaged with the first connecting end and the second connecting end, and a first limiting ring is provided at both ends of the outer pipe, and the first connecting end and the second connecting end are respectively sealed and connected with the two ends of the inner pipe, and a second limiting ring is provided on the pipe body of the inner pipe, and connecting ports are provided on the first connecting end and the second connecting end. The inner lining pipe and the outer pipe of the polyethylene pipe of this technical solution are connected by a chimeric connection to achieve the independence of the pipe bodies. A reserved gap is formed between the outer pipe and the inner lining pipe, so that the inner lining pipe will not cause heat transfer to the outer pipe, thus avoiding aging of the outer pipe caused by heat. When connecting the pipe bodies, it is only necessary to rotate and lock the threaded groove and the thread ring on the connecting end, without the need for external equipment, simplifying the cumbersome process of connecting the pipe bodies.

[0003] The disadvantage of the polyethylene tube disclosed above is that since the fluid medium transported by the polyethylene tube needs to be detected in real time, and the polyethylene tube itself does not have a detection point, the subsequent opening will destroy the stress distribution of the polyethylene tube and affect the quality. For this reason, we designed a polyethylene inner tube with detection points. Summary of the invention

[0004] The purpose of the utility model is to provide a polyethylene inner tube with detection points to solve the problems raised in the above background technology.

The purpose of such arrangement is to be able to route and wire inside the power threading tube, which is convenient for the layout of the circuit connection wires, and at the same time can improve the heat insulation protection effect of the circuit connection wires (for the environment used for conveying hot gas), and can also enhance the strength of the first inner tube section itself through the two power threading tubes.

The purpose of such a setting is to have good use strength, ensure strong alkali and strong acid resistance, and at the same time play a role in preventing combustion and rusting.

[0009] In the above-mentioned polyethylene inner tube with detection points, an integrally formed protruding gasket is provided at the outer ring of the puncture plugging rubber plug, and the protruding gasket is connected to the inner ring of the protective round cover. The purpose of such a setting is to improve the firmness of the connection between the puncture plugging rubber plug and the protective round cover, and ensure that the puncture plugging rubber plug will not loosen when the internal pressure of the second inner tube section changes.

[0010] In the above-mentioned polyethylene inner tube with detection points, a sealing tape is arranged at the thread groove of the protective round cover, and the protective round cover is connected to the thread section of the threaded connection part through the sealing tape. The purpose of such arrangement is to ensure the sealing of the connection between the protective round cover and the threaded connection part, and prevent the leakage of the fluid medium during transportation.

[0011] In the above-mentioned polyethylene inner tube with detection points, the end of the first inner tube segment and the end of the second inner tube segment are both provided with an integrally formed outer flange flange portion, and the outer surface of the first inner tube segment and the outer surface of the second inner tube segment are both provided with reinforcing ribs. The purpose of such a setting is to facilitate better penetration into the metal flange pipeline, so that the end of the first inner tube segment and the end of the second inner tube segment can fit the flange part of the pipeline more perfectly, improve the aesthetics and reduce the gap difference generated after assembly.

[0012] Compared with the prior art, the advantages of the polyethylene inner tube with detection points of the utility model are as follows: a detection point mechanism is set at the top opening of the second inner tube section; the detection point mechanism is composed of a fluororubber connecting section, a rubber connecting plug, a threaded connecting part, a protective round cover, a sealing puncture plug, a protruding gasket, a sealing tape and a leak-proof mesh plate and other structures, and adopts a puncture plugging method, which can quickly and effectively install the probe rod of the parameter detection equipment, improve the convenience of installation, and do not require subsequent opening for installation, thereby ensuring the overall stress distribution of the second inner tube section, ensuring the strength, and at the same time ensuring the sealing and firmness of the probe rod installation, and preventing leakage of the fluid medium; by installing an electric wire threading tube with a heat-insulating protective baffle inside the semicircular channel; wiring can be carried out inside the electric wire threading tube, which is convenient for the wiring layout of the circuit connection line, and can improve the heat insulation protection effect of the circuit connection line (for the environment used for conveying hot air), and at the same time, the strength of the first inner tube section itself can be enhanced by two electric wire threading tubes.
