Description

Technical Field

[0001] This utility model relates to the field of pipe fitting production and processing technology, and in particular to a PE hot melt pipe fitting. Background Technology

[0002] PE pipes and fittings are industrial pipes and connecting parts made from polyethylene resin. They are mainly divided into high-density, medium-density, and low-density polyethylene types, with core products including PE80 and PE100 grades, featuring corrosion resistance and good flexibility. They are widely used in municipal water supply, gas transmission, agricultural irrigation, and industrial raw material transportation.

[0003] However, traditional pipe fittings typically rely on simple scale lines or markings for positioning. During hot melting, deviations in insertion depth can easily lead to misalignment of the fusion area, affecting sealing performance. Furthermore, the sealing of traditional pipe fittings mainly depends on the fusion of materials after hot melting, resulting in a single sealing method. Under high pressure or long-term use, the risk of leakage at the interface is relatively high. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a PE hot-melt pipe fitting, which aims to improve the problems of insufficient positioning accuracy and poor sealing performance of traditional pipe fittings.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a PE hot melt pipe fitting, including a tee pipe, wherein a pipe is slidably connected to the outer wall of the tee pipe, a connecting pipe is provided on one side of the pipe, a sealing groove is provided on the outer wall of the pipe and the connecting pipe on the side adjacent to the connecting pipe, and a gasket is provided on one side of the connecting pipe.

[0006] The above technical solution involves inserting the connecting pipe of the pipe into the inner wall of the tee for quick connection and installation, allowing the sealing groove to engage with the elastic ring, and then using a gasket for assistance. This achieves initial positioning while creating multiple sealing effects, improving the sealing performance of the connection, reducing the risk of leakage at the interface, further enhancing the sealing reliability and connection stability of the pipe fittings, and ensuring the normal transport of media in the pipeline system.

[0007] Preferably, the outer wall of the three-way pipe is provided with a center line.

[0008] Preferably, the outer wall of the tee pipe is uniformly provided with multiple reinforcing rings.

[0009] Preferably, elastic rings are provided on the outer walls of both symmetrical ends of the tee pipe, and the elastic rings are engaged with the sealing grooves.

[0010] Preferably, the outer walls of both symmetrical ends of the tee pipe are provided with multiple anti-slip pads and textured anti-slip strips, which are evenly distributed around them.

[0011] Preferably, the inner walls of both symmetrical ends of the tee are provided with hot melt layer marking lines, the connecting pipe is slidably connected to the inner wall of the tee, the connecting pipe abuts against one side of the hot melt layer marking line, and the washer is slidably connected to the inner wall of the hot melt layer marking line.

[0012] Preferably, one end of the three-way pipe is provided with multiple positioning lines, which are evenly distributed around its center.

[0013] Preferably, the outer walls of the three ends of the tee are provided with scale lines.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the cooperation between components such as the hot melt layer marking line, elastic ring and sealing groove can accurately control the hot melt area, achieve initial positioning and form multiple seals at the same time, thereby reducing the risk of interface leakage and achieving accurate positioning and reliable sealing of the equipment.

[0015] 2. In this utility model, the structural rigidity is enhanced by reinforcing ribs and reinforcing rings to avoid deformation during transportation and installation; anti-slip pads and textured anti-slip strips improve the grip friction during construction and ensure the accuracy of hot melt alignment; positioning lines and scale lines assist in simplifying the installation process, ultimately achieving a robust structure and convenient construction of the equipment, which is suitable for various PE pipe connection scenarios.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0019] Reference Figure 1 and Figure 3 One embodiment of this utility model is a PE hot melt pipe fitting, including a tee pipe 1, a pipe 2 slidably connected to the outer wall of the tee pipe 1, a connecting pipe 11 provided on one side of the pipe 2, a sealing groove 9 opened on the outer wall of the pipe 2 near the connecting pipe 11, and a gasket 12 provided on one side of the connecting pipe 11.

[0020] Specifically, firstly, pipe 2 is inserted into tee 1, allowing connecting pipe 11 on one side of pipe 2 to slide against the inner wall of tee 1 until connecting pipe 11 abuts against the outer wall of the hot-melt layer marking line 10. The hot-melt layer marking line 10 limits the insertion depth of connecting pipe 11, facilitating its positioning and preventing subsequent connection deviations caused by excessive or shallow insertion. Simultaneously, the sealing groove 9 on pipe 2 and the elastic ring 8 interlock, further ensuring the relative position of connecting pipe 11 and tee 1. This prevents pipe 2 from shifting during hot-melt and creates a preliminary seal, enhancing the overall sealing effect of the equipment. Ultimately, this achieves precise positioning during installation, reduces operational errors, improves connection stability, lowers the risk of leakage at the interface, and makes pipe installation more convenient. Consequently, it enhances the sealing and stability of the pipeline system when transporting media, improving the overall reliability and safety of use.

[0021] Reference Figure 1 , Figure 2 and Figure 4 The outer wall of the tee pipe 1 is provided with multiple reinforcing ribs 3, which are evenly distributed around it; the outer wall of the tee pipe 1 is evenly provided with multiple reinforcing rings 4.

[0022] Specifically, by setting multiple reinforcing ribs 3 and reinforcing rings 4 on the outer wall of the tee pipe 1, and by the cooperation of the reinforcing ribs 3 and reinforcing rings 4, the overall structural rigidity of the pipe fitting is further improved, thereby avoiding deformation during transportation or installation and increasing the stability of the structure.

[0023] Reference Figures 2-4 The outer walls of both symmetrical ends of the tee pipe 1 are provided with elastic rings 8, and the elastic rings 8 are interlocked with the sealing grooves 9.

[0024] Specifically, the interlocking of the elastic ring 8 and the sealing groove 9 creates a sealing effect, which compensates for the sealing gap that may exist in the heat fusion connection, thereby reducing the risk of leakage at the interface. It can also help the pipe 2 and the tee pipe 1 to be accurately aligned during installation, thereby improving the stability of the equipment connection.

[0025] Reference Figure 1 and Figure 2 The outer walls of both symmetrical ends of the tee pipe 1 are provided with multiple anti-slip plates 5 and textured anti-slip strips 6, which are evenly distributed around them.

[0026] Specifically, the anti-slip sheet 5 and the textured anti-slip strip 6 work together to increase the friction of the hand grip during construction, thereby preventing slippage and ensuring accurate alignment of the tee pipe 1 and the pipe 2 during hot-melt connection. This reduces installation deviations caused by unstable grip, thereby improving construction quality and operational efficiency.

[0027] Reference Figures 2-4 The inner walls of both symmetrical ends of the tee pipe 1 are provided with hot melt layer marking lines 10. The connecting pipe 11 is slidably connected to the inner wall of the tee pipe 1 and abuts against one side of the hot melt layer marking line 10. The washer 12 is slidably connected to the inner wall of the hot melt layer marking line 10.

[0028] Specifically, the hot-melt layer marking line 10 can more accurately define the hot-melt area, avoiding deviations in the insertion depth of the connecting pipe 11, which could lead to inaccurate fusion. Combined with the gasket 12, it can further ensure the quality of the hot-melt connection and improve the reliability of the interface sealing and connection.

[0029] Reference Figure 1 and Figure 2 One end of the tee pipe 1 is provided with multiple positioning lines 7, which are evenly distributed around its center; the outer walls of the three ends of the tee pipe 1 are provided with scale lines.

[0030] Specifically, the positioning line 7 can help to quickly find the installation angle during construction. In conjunction with the scale lines on the outer walls of the three ends of the tee pipe 1, the insertion depth of the pipe 2 can be controlled more accurately. The combination of the positioning line 7 and the scale lines can simplify the installation alignment process, reduce installation problems caused by deviations in angle or depth, and thus improve construction efficiency and connection accuracy.

[0031] Working principle: When performing hot-melt connection, the connecting pipe 11 of the pipe 2 is first inserted into the inner wall of the tee pipe 1. Then, the pipe 2 is pushed so that the connecting pipe 11 abuts against the outer wall of the hot-melt layer marking line 10. The hot-melt layer marking line 10 facilitates precise control of the hot-melt area. At the same time, the elastic ring 8 and the sealing groove 9 of the pipe 2 are interlocked. One side of the connecting pipe 11 abuts against the hot-melt layer marking line 10 on the inner wall of the tee pipe 1. The gasket 12 is interlocked in the hot-melt layer marking line 10. This allows the equipment to achieve initial positioning while forming multiple seals, thereby playing a sealing role and reducing the risk of leakage at the interface. During heating, the PE material of the tee pipe 1 and the pipe 2 is melted with the hot-melt layer marking line 10 as a reference. After cooling, an integrated sealing structure is formed, thereby achieving accurate positioning and reliable sealing of the equipment. By setting a centerline 3 and multiple reinforcing rings 4 on the outer wall of the tee pipe 1, the centerline 3 and reinforcing rings 4 cooperate with each other, thereby further enhancing the structural rigidity of the tee pipe 1 and preventing deformation during transportation and installation. The anti-slip plate 5 and the textured anti-slip strip 6 cooperate with each other to increase the gripping friction during construction and ensure the alignment accuracy of the hot-melt process. At the same time, the positioning line 7 and the scale line can help simplify the alignment process during installation, thereby improving the construction efficiency. Ultimately, the structural strength and construction convenience of the pipe fitting are improved, making it suitable for various PE pipe diversion and connection scenarios.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
