Especially in the secondary water supply system of high-rise and super high-rise buildings, PSP pipes provide an effective solution.

[0003] In the prior art, connecting two sections of PSP pipes usually requires grinding chamfers at the connecting ends of the two sections of PSP pipes, and then inserting the connecting ends of the two pipes into a connecting piece, in which an electromagnetic plate is provided. The connecting piece is then clamped by an external clamping device, and a hot-melt connection between the two pipes is achieved by electromagnetic heating.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will, in conjunction with the accompanying Figures 1-3 drawings of the embodiments of the present utility model, clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the scope of protection of the present utility model.

[0025] As Figures 1-3 shown: It includes a support pipe 100 and a connecting pipe 200 disposed inside the inner circle of the support pipe 100. In this embodiment, the support pipe 100 is located at the middle position of the connecting pipe 200. When connecting two PSP pipes, the connecting pipe 200 can be inserted into the flared end of the PSP pipe material. A heating element 202 is further provided on the outer surface of the connecting pipe 200. When the heating element 202 works, it can conduct heat to the connecting pipe 200, thereby making the connecting pipe 200 in a molten state. Two connecting grooves 101 are vertically provided on the support pipe 100. The two connecting grooves 101 are symmetrically arranged on the support pipe 100 and communicate with the heating element 202. An electrode post 102 is provided in the connecting groove 101. The electrode post 102 is electrically connected to the heating element 202. Through an external device, the heating element 202 can be made to work through the electrode post 102.

[0026] When connecting the PSP pipes, insert the ends of the two PSP pipes into both ends of the connecting pipe 200, and then drive the heating element 202 to work through the electrode post 102 by an external device. When the heating element 202 works, it can transfer heat to the connecting pipe 200, thereby making the connecting pipe 200 in a molten state. The connecting pipe 200 can be welded to the inner side wall of the PSP pipe, and thus the connection between two sections of PSP pipe materials can be completed.

[0027] As Figure 2 、 3 shown,

[0028] The heating element is a heating resistance wire wound around the outer surface of the connecting pipe. That is, the heating wire can be controlled to work through the electrode post 102. After being powered on, it will emit heat and provide heat energy, thereby being able to transfer heat to the connecting pipe 200.

[0029] As Figure 2 、 3 shown,

[0030] The connecting pipe 200 is provided with two storage grooves 201. In this embodiment, the storage grooves are located inside the connecting pipe and are both annular structures. The two storage grooves 201 are respectively located at both ends of the connecting pipe 200. A copper wire layer 203 is provided in each storage groove 201. Both ends of the heating element 202 are respectively connected to the two copper wire layers 203. Corresponding to the copper wire layer 203, support ring plates 204 are provided at both ends of the inner side of the connecting pipe 200. Through the copper wire layer 203, heat can be conveniently conducted to the support ring plates 204, and the support ring plates 204 can transfer heat to the connecting pipe 200 more evenly. Moreover, the support ring plates 204 can also support the connecting pipe 200 when the connecting pipe 200 enters the molten state, preventing the connecting pipe 200 from being severely deformed after entering the molten state.

[0031] As Figure 1 、 2 、shown in FIG. 3,

[0032] Both ends of the connecting pipe 200 are provided with a first relief portion 205. In this embodiment, the first relief portion 205 is formed by setting the end of the connecting pipe 200 as a conical structure. This conical structure forms an annular inclined surface at both ends of the connecting pipe 200. The inclined surface is located on the outer side wall of the connecting pipe 200 and is arranged towards the end far from the support pipe 100. The first relief portion 205 can enable the pipe to be inserted into the outer side wall of the connecting pipe 200. If there is a slight deviation between the end of the pipe and the end of the connecting pipe 200, the end of the pipe can abut against the inclined surface of the first relief portion 205, making it convenient for the pipe to be inserted outside the connecting pipe 200.

[0033] As Figure 2 shown,

[0034] Both ends of the support pipe 100 are further provided with positioning pipes 300. The positioning pipes 300 are coaxially arranged with the support pipe 100. The positioning pipes 300 are located outside the connecting pipe 200. That is, before the pipes are connected, the pipe material needs to be inserted between the positioning pipes 300 and the connecting pipe 200. Thus, when the connecting pipe 200 is melted to connect the two pipes, the positioning pipes 300 can assist in positioning the two pipes, and further cooperate with the support ring plates 204 to prevent the two pipes from being connected obliquely.

[0035] As Figure 1 、 2 、shown in FIGS. 3,

[0036] A second yielding portion 301 is provided at one end of the positioning tube 300 away from the supporting tube 100. In the present embodiment, the second yielding portion 301 is a conical structure for setting the end of the positioning tube 300. The conical structure forms an annular inclined surface at the end of the positioning tube 300. The inclined surface is located in the inner circle of the positioning tube 300 and is arranged toward a side away from the supporting tube 100. The second yielding portion 301 enables the end of the pipe to contact the inclined surface of the second yielding portion 301 when the pipe is inserted into the positioning tube 300 if there is a slight deviation between the end of the pipe and the end of the positioning tube 300, so that the pipe can be easily inserted into the outside of the connecting tube 200.

[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0038] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
