Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to a PE pipe structure for an equal diameter tee. Background Technology

[0002] In the field of pipeline engineering, tees are commonly used pipe fittings to achieve flow branching or merging. Equal-diameter PE tees, as a special type of tee, have inlet and outlet diameters of equal diameter, making them suitable for applications with high flow and pressure requirements. Currently, various equal-diameter PE tee structures exist on the market, but they still suffer from problems such as insufficient connection strength, poor sealing, and inconvenient installation in their structural design and performance. Some tee fittings lack necessary support structures at the connection points, leading to deformation or leakage when the pipeline system is subjected to significant pressure or temperature changes. These problems not only affect the normal operation of the pipeline system but also increase maintenance and replacement costs. Therefore, how to design an equal-diameter PE tee structure with a reasonable structure, high connection strength, good sealing performance, and convenient installation has become an urgent technical problem to be solved in the current pipeline engineering field.

[0019] The technical solutions of this utility model application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described application is only a part of this utility model application, not all of it. Based on the application in this utility model, all other applications obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1-2 This utility model discloses a PE pipe structure for an equal diameter tee:

[0021] like Figures 1-2As shown, this application discloses an equal diameter tee PE pipe structure, including an inlet pipe 1 and a first outlet pipe 2 whose center is on the same center line as the inlet pipe 1. A second outlet pipe 3 is provided in a direction perpendicular to the straight line connecting the center point of the inlet pipe 1 and the center point of the first outlet pipe 2. An external thread 101 is provided on the periphery of the port of the inlet pipe 1. A stop 23 is provided at the ports of the first outlet pipe 2 and the second outlet pipe 3 by heat fusion.

[0022] Specifically, the inlet pipe 1 has an externally threaded port, which facilitates connection with other pipes or equipment, improving the stability and sealing of the connection. Tightening the external thread 101 ensures that the pipe connection will not loosen due to fluid pressure, thus guaranteeing the safe operation of the pipeline system. The center of the first outlet pipe 2 is on the same center line as the center of the inlet pipe 1, and it is directly connected to the inlet pipe 1 to form a straight pipe, which makes the fluid flow in the pipe smoother, reduces fluid resistance, and improves the conveying efficiency of the pipeline system. At the same time, the straight pipe design also facilitates installation and maintenance. The second outlet pipe 3 is perpendicularly connected to the straight pipe. This arrangement allows the second outlet pipe 3 to form a 90° angle with the other two pipes, which facilitates the layout and connection of the pipeline in a limited space. The straight distance between the second outlet pipe 3 and the inlet pipe 1 and the straight distance between the second outlet pipe 3 and the first outlet pipe 2 are equal, ensuring the balance and stability of the pipeline system.

[0023] Furthermore, both the first outlet pipe 2 and the second outlet pipe 3 have a baffle 23 installed at their ports by heat fusion. The cross-sectional shape of the baffle 23 is a regular hexagon. The baffle 23 can enhance the strength and rigidity of the pipe port and prevent damage due to external impact or collision. At the same time, the regular hexagonal cross-sectional shape makes the baffle 23 easier to identify and operate, and facilitates installation and disassembly.

[0024] Furthermore, the tee pipes are all made of polyethylene, and both the straight pipe and the second outlet pipe 3 have internal threads. Polyethylene has excellent corrosion resistance and wear resistance, which can extend the service life of the pipe. The internal threads can further enhance the stability and sealing of the pipe connection and prevent fluid leakage.

[0025] Furthermore, the thread angle of the internal thread is 60°, and the cross-sectional shape of the internal thread is trapezoidal. This design gives the internal thread a self-locking capability, which can further ensure the tightness of the connection between the tee pipe and other pipes or equipment.

[0026] 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.
