Description

Technical Field

[0001] The utility model relates to the field of pipeline connectors, in particular to a Y-type three-way connector. Background Art

[0002] Tee is also called pipe tee or tee pipe fitting, tee joint, etc. It is mainly used to change the direction of the fluid and is used at the branch pipe of the main pipeline. It can be classified according to the size of the pipe diameter. It is generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic and other materials.

[0003] For example, the patent with the authorization announcement number CN205896518U discloses a Y-type three-way pipe fitting of full-diameter reinforced injection-molded polyethylene plastic, which belongs to the field of plastic pipe fitting technology and aims to solve the problems of unreasonable structural design, small internal diameter, high operating energy consumption and potential safety hazards of existing injection-molded Y-type three-way pipe fittings. The Y-type three-way pipe fitting body it adopts is a Y-type three-way pipe fitting body composed of a main pipe section and a branch pipe section as a one-time injection molding structure. The main pipe section is a U-shaped head, which is connected to the branch pipe section in parallel. The inner hole of the main pipe section is tangentially connected to the inner hole of the corresponding branch pipe section on both sides to form an extended connecting channel, wherein the cross-sectional area of ​​the single-side extended connecting channel is greater than 5% of the cross-sectional area of ​​the inner hole of the corresponding branch pipe section, and the sum of the cross-sectional areas of the two extended connecting channels on both sides is greater than 30% of the cross-sectional area of ​​the inner hole of the main pipe section.

[0004] The above patent has a simple and practical structure, with small resistance to medium passing through, and is suitable for supporting water pressure pipeline systems such as ground source heat pumps; however, the disadvantage of the above patent is that the tee in the above patent lacks an auxiliary fixing structure, and the fixation is not stable enough.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. The components of the embodiments of the present utility model usually described and illustrated in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0027] Please refer to Figure 1-8 , a Y-shaped three-way joint, which includes a main pipe 1 and also includes two branch pipes 2 communicated with the main pipe 1,

[0028] The main pipe 1 and the branch pipes 2 are integrally formed and are both made of polyethylene plastic; the cross-sections of the main pipe 1 and the branch pipes 2 are both circular, and the cross-sectional area of the branch pipes 2 is greater than one-half of the cross-sectional area of the main pipe 1;

[0029] The branch pipes 2 are located on the left and right sides at the top of the main pipe 1 and are symmetrically arranged, and the whole is in a Y shape;

[0030] At the same time, one end of the main pipe 1 close to the branch pipes 2 is tapered, which plays a role in guiding the water flow from the main pipe to the branch pipes 2;

[0031] In this solution, at least two annular first positioning ridges 3 are further provided on the outer wall of the lower end of the main pipeline 1, and a first clamping groove 4 for clamping the clamp is formed between the two circles of first positioning ridges 3 to prevent the clamp from displacing;

[0032] Correspondingly, at least two annular second positioning ridges 5 are provided on the outer wall of the top end of the branch pipeline 2, and a second clamping groove 6 for clamping the clamp is formed between the two circles of second positioning ridges 5 to prevent the clamp from displacing;

[0033] Meanwhile, in this solution, a threaded hole 7 is further opened in the first clamping groove 4. When the main pipeline of the tee is connected to the pipeline, by screwing a bolt into the threaded hole 7, the tee can be prevented from rotating and displacing relative to the pipeline;

[0034] Meanwhile, in order to increase the sealing performance when the main pipeline 1 is connected to the pipeline, in this solution, a sealing ring 8 is further included. The sealing ring 8 is cylindrical, and a plurality of positioning rings 9 are evenly spaced on the outer wall of the sealing ring 8. At the same time, a plurality of positioning grooves 10 are evenly opened on the inner wall of the main pipeline 1, and the positioning grooves 10 and the positioning rings 9 are arranged in one-to-one correspondence; The sealing ring 8 is made of silica gel.

[0035] During the installation of this solution, as Figure 8 shown, the pipeline is inserted into one end of the main pipeline 1. At this time, there is a sealing ring 8 between the outer wall of the pipeline and the inner wall of the main pipeline 1. The silica gel sealing ring 8 is used to fill the gap between the outer wall and the inner wall of the main pipeline 1, and the cooperation of the positioning grooves 10 and the positioning rings 9 helps to prevent the sealing ring from moving up and down.

[0036] As Figure 9-10 shown, meanwhile, in another embodiment of this solution, a plurality of flow guiding plates 11 are horizontally spaced at the connection between the main pipeline 1 and the branch pipeline 2. The flow guiding plates 11 are mainly used to guide the fluid flowing from the main pipeline 1 to the branch pipeline 2, prevent the fluid from generating turbulence when impacting the connection between the main pipeline 1 and the branch pipeline 2, and further prevent the tee from vibrating due to the turbulence.
