Description

Technical Field

[0001] This utility model relates to the field of refrigeration machinery technology, and more specifically to a three-way pipe assembly. Background Technology

[0002] A tee fitting, also known as a pipe tee or tee pipe fitting, is a pipe fitting with three ports: one inlet and two outlets, or two inlets and one outlet. It comes in T-shape and Y-shape, with equal diameter ports and different diameter ports. It is used where three identical or different pipes converge or where a branch pipe is needed on a main pipe, and is mainly used to change the direction of fluid flow.

[0003] Existing air conditioning tee components, such as Figure 9 As shown, it is constructed by welding a T-shaped connector I, a left connecting bend II, and a right connecting bend III or branch pipe IV. For ease of connection, all components are made of copper. The T-shaped tee is manufactured using casting or extrusion processes. The socket ends require end processing to meet the requirements of insertion and stop. This process is complex, involving multiple steps such as cutting, lead filling, extrusion, lead removal, cleaning, and shaping. Furthermore, it causes significant environmental pollution due to the use of lead, posing hazards to the environment and operators, necessitating strict operational controls and protective measures. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a tee connector assembly with a reasonable structure and convenient processing.

[0005] A three-way connector assembly includes a first bend, a second bend, and a third bend. The first bend, the second bend, and the third bend are connected to a joint. The joint is a shell-shaped structure closed on one side, formed by stretching and integral molding. A symmetrical side hole with outward convexity or inward concavity is provided in the middle position. The distance between the second bend and the bottom surface of the closed side is set. All transitions of the joint are rounded. The angle between the first bend and the second bend and the third bend is set.

[0006] This practical design features a reasonable structure, low cost, simple and efficient process, high yield, and is environmentally friendly with no pollution, posing no harm to the environment or operators / users. It reduces costs and improves economic efficiency. The distance between the second and third bends and the bottom surface of the closed side is designed for good strength.

[0007] As a further improvement and supplement to the above solution, this utility model also includes the following additional technical features:

[0008] A third connecting pipe is provided on the outside of the first bend, a first connecting pipe is provided between the second bend and the joint, and a second connecting pipe is provided between the third bend and the joint.

[0009] The first and second connecting pipes are equipped with flared sections, and the first bend has a constricted section on one side. The first bend, the first connecting pipe, and the second connecting pipe are all made of stainless steel. The structure is reasonable and positioning is convenient.

[0010] The joint is equipped with a connector on its inner or outer side, and the other end of the connector is provided with a first bend. The structure is reasonable and effectively strengthens the structure.

[0011] The joint has inward protrusions on both sides, which can be flat or curved. The second and third bends are connected by an adapter. The structure is reasonable and effectively strengthens the structure.

[0012] The connector is made of stainless steel. This reduces cost and improves economic efficiency.

[0013] The second bend, third bend, and third connecting pipe are made of copper, while the joints are made of stainless steel. The copper material facilitates connection with other parts. The double-layer metal structure (inner steel, outer copper) can withstand pressure and strength, preventing the copper pipe from deforming under stress during line testing and causing the clamps to detach.

[0014] The following advantages can be achieved by using this utility model: The structure is reasonable, the strength meets performance requirements, the cost is low, the process is simple and efficient, the yield is high, and it is also green and environmentally friendly, causing no pollution or harm to the environment or operators / users. The double-layer metal structure (inner steel, outer copper) can withstand pressure and strength, preventing the copper tube from deforming under stress during line testing and causing the clamps to fall off. This reduces costs and improves economic efficiency. The distance between the second and third bends and the bottom surface of the closed side is designed for good strength.
