Description

Technical Field

[0001] This utility model relates to the field of water pipes, and in particular to a PSP steel-plastic composite pipe for preventing water pollution. Background Technology

[0002] In indoor water supply systems, steel-plastic composite pipes are typically used for the water supply pipes. These pipes are connected by threads, requiring a threading machine to create threads at both ends of the pipe. During the threading process, lead oil from the threading machine may enter the pre-installed pipes. Although flushing and disinfection tests are conducted after pipe installation, this can still potentially affect the quality of drinking water used subsequently. The connections between steel-plastic composite pipes also use fittings with plastic linings. Due to different manufacturing standards among fitting manufacturers, the length of the plastic lining in the fittings varies. This can lead to misalignment of the plastic lining during pipe-fitting connections. After the system is put into use, drinking water will come into contact with the inner wall of the galvanized steel pipe, affecting water quality.

[0003] Therefore, a PSP steel-plastic composite pipe for preventing water pollution is proposed. Utility Model Content

[0004] In order to improve the problem that water quality is easily polluted during water transportation in existing water supply pipelines, this utility model provides a PSP steel-plastic composite pipe to prevent water pollution.

[0005] This utility model provides a PSP steel-plastic composite pipe for preventing water pollution, using the following technical solution:

[0006] A PSP steel-plastic composite pipe for preventing water pollution includes a connecting pipe and connecting pipe heads fixedly installed at both ends of the connecting pipe. The PSP steel-plastic composite pipe body is installed inside the connecting pipe head. The PSP steel-plastic composite pipe body includes an intermediate steel pipe and a polyethylene plastic layer fixedly connected to the inner and outer sides of the intermediate steel pipe. A filter mechanism is installed on the connecting pipe.

[0007] By adopting the above technical solution, the use of PSP steel-plastic composite pressure pipe can effectively ensure that the water quality of the pipeline is not polluted for a long time, because the inner and outer sides of the PSP steel-plastic composite pressure pipe are both polyethylene plastic layers, and the corrosion resistance and oxidation resistance of the pipe are better than those of steel-plastic composite pressure pipe.

[0008] Optionally, the filtration mechanism includes a connecting seat, an activated carbon filter cartridge, and a transparent outer cover. A baffle is fixedly installed in the middle of the connecting tube, which divides the internal space of the connecting tube into two chambers. A connecting seat is fixedly installed at the bottom of the connecting tube, and two through holes are opened on the connecting seat. The two through holes communicate with the two chambers respectively. An activated carbon filter cartridge is installed in the internal thread of one of the through holes, and a transparent outer cover is threaded on the connecting seat.

[0009] By adopting the above technical solution, when water flows from the inside of one of the chambers into the inside of the activated carbon filter cartridge through the corresponding through hole, the water then flows into the inside of the transparent outer cover, and then flows into the inside of another chamber through another through hole. The activated carbon filter cartridge can filter and adsorb impurities in the water, thereby improving water quality.

[0010] Optionally, crossbars are fixedly installed on both sides of the transparent cover.

[0011] By adopting the above technical solution, the crossbar is designed to facilitate the rotation of the transparent cover, thereby making it easier to assemble and disassemble the transparent cover and the connecting seat.

[0012] Optionally, curved connecting blocks are fixedly installed between both sides of the baffle and the inner wall of the connecting pipe.

[0013] By adopting the above technical solution, the curved connecting block not only improves the connection strength between the baffle and the connecting pipe, thereby enhancing the baffle's resistance to water flow impact, but also guides the water flow and reduces the impact of the water flow on the baffle.

[0014] Optionally, an inner tube is fixedly connected to the inner wall of both ends of the connecting pipe, and an annular groove is formed between the inner tube and the connecting pipe head. The end of the PSP steel-plastic composite pipe body is inserted into the inside of the annular groove.

[0015] By adopting the above technical solution, after the main body of the PSP steel-plastic composite pipe is cut, it is inserted into the inside of the annular groove. Then, the main body of the PSP steel-plastic composite pipe is welded to the connecting pipe head by electromagnetic induction double hot melt welding. At the same time, the main body of the PSP steel-plastic composite pipe is also connected to the inner pipe, thereby isolating the middle steel pipe on the cross section of the PSP steel-plastic composite pipe from the water quality and preventing water pollution.

[0016] Optionally, support rings are fixedly connected to both the inner and outer sides of the intermediate steel pipe.

[0017] By adopting the above technical solution and setting the support ring, the overall compressive strength of the PSP steel-plastic composite pipe is improved.

[0018] Optionally, a heat-conducting metal strip is fixedly connected between each of the two adjacent support rings, and the bottom of the heat-conducting metal strip is fixedly connected to the surface of the intermediate steel pipe.

[0019] By adopting the above technical solution and setting up heat-conducting metal strips, heat transfer is facilitated within the welding part of the PSP steel-plastic composite pipe body during fusion welding, thereby improving welding efficiency.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. Compared with traditional steel-plastic composite pipes, this utility model uses PSP steel-plastic composite pressure pipes, which can effectively ensure that the water quality in the pipeline is not polluted for a long time. This is because the inner and outer sides of the PSP steel-plastic composite pressure pipe are both polyethylene plastic layers, and the corrosion resistance and oxidation resistance of the pipe are superior to those of traditional steel-plastic composite pressure pipes. Moreover, the activated carbon filter cartridge in the filtration mechanism can filter and adsorb impurities in the water, improving water quality. In addition, if leaks occur during the pipeline's use, there is no need to dismantle the pipeline for repair; only secondary electrofusion at the pipe connection is required, which improves work efficiency.

[0022] 2. This utility model uses electromagnetic induction double hot-melt welding to weld the connecting pipe head to the main body of the PSP steel-plastic composite pipe. If leakage occurs during the use of the pipeline, there is no need to dismantle the pipeline for repair. Only secondary electrofusion at the pipe connection is required, which helps to improve work efficiency. Attached Figure Description

[0029] The following description, in conjunction with the embodiments of this utility model, includes appendices. Figure 1-4The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Please refer to Figure 1-2 A PSP steel-plastic composite pipe for preventing water pollution includes a connecting pipe 1 and connecting pipe heads 2 fixedly installed at both ends of the connecting pipe 1. The PSP steel-plastic composite pipe body 3 is installed inside the connecting pipe head 2. The PSP steel-plastic composite pipe body 3 and the connecting pipe head 2 are connected by electromagnetic induction double hot melt welding. Compared with traditional steel-plastic composite pipes, if leakage occurs during the use of the pipeline, there is no need to dismantle the pipeline for repair. Only secondary electrofusion at the pipeline connection is required, which effectively improves work efficiency. The PSP steel-plastic composite pipe body 3 includes a central steel pipe 31 and polyethylene plastic layers 32 fixedly connected to the inner and outer sides of the central steel pipe 31. Inner pipes 11 are fixedly connected to the inner walls of both ends of the connecting pipe 1. An annular groove 12 is formed between the inner pipe 11 and the connecting pipe head 2. The end of the PSP steel-plastic composite pipe body is inserted into the annular groove 12. With this structure, after the PSP steel-plastic composite pipe body 3 is cut, it is inserted into the annular groove 12. Then, the PSP steel-plastic composite pipe body 3 and the connecting pipe head 2 are welded together by electromagnetic induction double hot melt welding. At the same time, the PSP steel-plastic composite pipe body 3 is also connected to the inner pipe 11, thereby isolating the central steel pipe 31 on the cross section of the PSP steel-plastic composite pipe body 3 from the water quality and preventing water pollution.

[0031] Reference Figure 3 and Figure 4 Support rings 13 are fixedly connected to both the inner and outer sides of the intermediate steel pipe 31. The support rings 13 improve the overall compressive strength of the PSP steel-plastic composite pipe body 3. A heat-conducting metal strip 14 is fixedly connected between each adjacent support ring 13. The bottom of the heat-conducting metal strip 14 is fixedly connected to the surface of the intermediate steel pipe 31. The heat-conducting metal strip 14 facilitates the transfer of heat within the welded part of the PSP steel-plastic composite pipe body 3 during fusion welding, thereby improving welding efficiency.

[0032] Reference Figure 1 and Figure 2A filter mechanism is installed on the connecting pipe 1. The filter mechanism includes a connecting seat 4, an activated carbon filter cartridge 5, and a transparent outer cover 6. A baffle 7 is fixedly installed in the middle of the connecting pipe 1. Curved connecting blocks 15 are fixedly installed on both sides of the baffle 7 and the inner wall of the connecting pipe 1. The setting of the curved connecting blocks 15 improves the connection strength between the baffle 7 and the connecting pipe 1, thereby improving the resistance of the baffle 7 to water flow impact. On the other hand, it guides the water flow and reduces the impact effect of the water flow on the baffle 7. The baffle 7 divides the internal space of the connecting pipe 1 into two chambers 8. A connecting seat 4 is fixedly installed at the bottom of the connecting pipe 1. The connecting seat 4 has two through holes 9, which communicate with the two chambers 8 respectively. An activated carbon filter cartridge 5 is threaded into one of the through holes 9. A transparent cover 6 is threaded onto the connecting seat 4. When water flows from the inside of one chamber 8 through the corresponding through hole 9 into the inside of the activated carbon filter cartridge 5, the water then flows into the inside of the transparent cover 6, and then flows into the other chamber 8 through the other through hole 9. The activated carbon filter cartridge 5 can filter and adsorb impurities in the water, improving water quality. Moreover, the transparent cover 6 facilitates observation of the internal conditions. The transparent cover 6 and the activated carbon filter cartridge 5 are connected by threads, making it easy to disassemble and clean the impurities inside the activated carbon filter cartridge 5. Crossbars 10 are fixedly installed on both sides of the transparent cover 6. The crossbars 10 facilitate the rotation of the transparent cover 6, thereby facilitating the assembly and disassembly of the transparent cover 6 and the connecting seat 4.

[0033] The implementation principle of this utility model is as follows:

[0034] In use, one end of the PSP steel-plastic composite pipe body 3 is inserted into the annular groove 12 inside the connecting pipe head 2, and then the connecting pipe head 2 and the PSP steel-plastic composite pipe body 3 are welded together using electromagnetic induction double heat fusion. Since the PSP steel-plastic composite pipe body 3 consists of a central steel pipe 31 and polyethylene plastic layers 32 fixedly connected to the inner and outer sides of the central steel pipe 31, the central steel pipe 31 in the PSP steel-plastic composite pipe body 3 will not directly contact the water, which helps ensure water quality. Moreover, compared with traditional steel-plastic composite pipes, if leaks occur during pipeline use, there is no need to dismantle the pipeline for repairs. Only secondary electrofusion is needed at the pipe connection, which effectively improves work efficiency. When water flows from the steel-plastic composite pipe body 3 to the inside of the connecting pipe 1, under the action of the baffle 7, the water flows from the inside of one of the chambers 8 through the corresponding through hole 9 into the inside of the activated carbon filter cartridge 5. Then, the water flows into the inside of the transparent outer cover 6, and then flows into the inside of another chamber 8 through another through hole 9. The activated carbon filter cartridge 5 can filter and adsorb impurities in the water, improve water quality. Moreover, the transparent outer cover 6 and the activated carbon filter cartridge 5 are connected and installed by threaded connection, which makes it easy to disassemble and clean the impurities inside the activated carbon filter cartridge 5.

[0035] In summary, compared with traditional steel-plastic composite pipes, this device using PSP steel-plastic composite pressure pipes can effectively ensure that the water quality in the pipeline is not polluted for a long time. This is because the inner and outer sides of the PSP steel-plastic composite pressure pipe are both polyethylene plastic layers 32, and the corrosion resistance and oxidation resistance of the pipe are superior to those of traditional steel-plastic composite pressure pipes. Moreover, the activated carbon filter cartridge 5 in the filtration mechanism can filter and adsorb impurities in the water, improving water quality. In addition, if leaks occur during pipeline use, there is no need to dismantle the pipeline for repair; only secondary electrofusion at the pipe connection is required, which helps to improve work efficiency.
