Description

Technical Field

[0001] This application belongs to the field of tee pipe technology and relates to a U-shaped double-clamping variable diameter tee. Background Technology

[0002] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: Although some tee fittings on the market have the function of 90° turning or diameter change, they do not have the function of connecting threaded pipes when 90° turning and pipe diameter change. As the requirements of pipeline systems for efficient installation and high sealing performance continue to increase, the existing tee fitting connection technology faces challenges. In some complex pipeline layouts, such as when 90° turning and pipe diameter change are required, ordinary tees cannot well take into account the functions of diameter change and turning.

[0003] Therefore, how to provide a U-shaped double-press reducing tee to achieve 90° turning and change pipe diameter, and connect to an external threaded pipe has become an urgent technical problem to be solved. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this application aims to provide a U-shaped double-press reducing tee that can achieve 90° turning and change the pipe diameter and connect to an external threaded pipe.

[0005] This application is achieved through the following technical solution.

[0006] This technical solution provides a U-shaped double-press reducing tee, including: a stainless steel double-press half-connector A and a stainless steel double-press half-connector B, and a stainless steel short pipe with both ends fixedly connected to the stainless steel double-press half-connector A and the stainless steel double-press half-connector B respectively. The stainless steel short pipe is externally fixedly connected with at least one external threaded connector.

[0007] Wherein, the inner and outer diameters of the external threaded connector are both smaller than the inner and outer diameters of the stainless steel short pipe, the inner and outer diameters of the stainless steel short pipe are the same as those of the stainless steel double crimp half connector A and stainless steel double crimp half connector B, and / or, the inner and outer diameters of the stainless steel short pipe are both larger than those of the stainless steel double crimp half connector A and stainless steel double crimp half connector B.

[0008] The present invention is further configured such that the stainless steel short pipe is a cylindrical pipe, and the pipe has an installation hole in the direction parallel to the ground, and the external threaded joint is installed in the hole.

[0009] The present invention is further configured such that the stainless steel short pipe is a polygonal cylindrical pipe with a plane having an installation hole on its exterior, and / or multiple planes having installation holes on its exterior, and the external threaded interface is fixed in the hole on the plane.

[0010] The angle between the plane connected to the stainless steel short pipe and the ground is α, where 0° < α < 180°.

[0011] The present invention is further configured such that the stainless steel short pipe is a regular polygonal cylindrical pipe, and the pipe has an installation hole within at least one plane on its exterior, and the external threaded interface is fixed in the hole on the plane.

[0012] The present invention is further configured such that valves are provided at the connection ends of the stainless steel double crimp half-joint A and stainless steel double crimp half-joint B with the stainless steel short pipe, and / or valves are provided at both ends of the stainless steel short pipe.

[0013] The present invention is further configured such that both the stainless steel short pipe and the external threaded joint are made of stainless steel.

[0014] The present invention is further configured such that the stainless steel short pipe is made of stainless steel and the external threaded joint is made of synthetic plastic.

[0015] The above technical solution has the following technical effects: By adding a short pipe with an external threaded connector to the outside of the original double-press-fit half-connector, the independent double-press-fit half-connectors are connected together to form a three-dimensional tee fitting. This can play a three-dimensional diversion role in the user's construction site. That is, the tee has a 90° U-shaped structure. Its design is based on the principle of fluid mechanics: when the fluid enters one port of the tee, the flow direction of the fluid will change due to the 90° turning design. Moreover, this 90° turning design can accurately control the flow direction of the fluid, so that the fluid enters other branch pipes according to the preset pipe layout, which meets the needs of complex pipe systems. For example, in the water supply and drainage system of a building, the vertical water flow is accurately directed to the horizontal branch pipe to achieve three-dimensional turning. At the same time, the integrated structure avoids the cumbersome operation during installation.

[0026] This utility model discloses a U-shaped double-clamping variable diameter tee, such as Figures 1-5 As shown, it includes: a stainless steel double crimp half-connector A1 and a stainless steel double crimp half-connector B2, and a stainless steel short pipe 3 whose two ends are fixedly connected to the stainless steel double crimp half-connector A1 and the stainless steel double crimp half-connector B2 respectively. The stainless steel short pipe 3 is externally fixedly connected to at least one external threaded connector 4.

[0027] Among them, the inner and outer diameters of the external threaded connector 4 are smaller than the inner and outer diameters of the stainless steel short pipe 3, the inner and outer diameters of the stainless steel short pipe 3 are the same as those of the stainless steel double crimp half connector A1 and the stainless steel double crimp half connector B2, and / or the inner and outer diameters of the stainless steel short pipe 3 are larger than those of the stainless steel double crimp half connector A1 and the stainless steel double crimp half connector B2.

[0028] It should be noted that both stainless steel double-press half-fitting connector A1 and stainless steel double-press half-fitting connector B2 are press-fit half-fitting connectors with symmetrical structures. The two ends of the stainless steel short pipe 3 are fixedly connected to the stainless steel double-press half-fitting connector A1 and stainless steel double-press half-fitting connector B2 respectively, forming an integrated structure. At this time, the external threaded connector 4 set on the outside of the stainless steel short pipe 3 can be connected to a branch pipe to form a flow splitting structure perpendicular to the above integrated structure. The inner diameter of the stainless steel short pipe 3 and the external threaded connector 4 can be adjusted according to actual needs to achieve changes in the liquid flow rate inside the pipe.

[0029] like Figure 4 As shown, the stainless steel short pipe 3 is a cylindrical pipe with an installation hole in the direction parallel to the ground where the pipe is located, and the external threaded connector 4 is installed in the hole.

[0030] like Figure 5 As shown, the stainless steel short pipe 3 is a polygonal cylindrical pipe with a plane with a mounting hole on its exterior, and / or multiple planes with mounting holes on its exterior, and the external threaded interface 4 is fixed in the hole on the plane.

[0031] The angle between the plane connected to the stainless steel short pipe 3 and the ground is α, where 0° < α < 180°.

[0032] like Figure 5 As shown, the stainless steel short pipe 3 is a regular polygonal cylindrical pipe. The pipe has an installation hole within at least one plane on its exterior, and the external threaded interface 4 is fixed in the hole on the plane.

[0033] It should be noted that the stainless steel short pipe 3 can be cast into a connection pipe structure with different numbers of planes, depending on the number of branch pipes to be connected, and its interior can be set as a hollow cylindrical structure.

[0034] like Figures 1-5 As shown, valves are provided at the connection ends of stainless steel double crimp half-fitting connector A1, stainless steel double crimp half-fitting connector B2 and stainless steel short pipe 3, and / or, valves are provided at both ends of stainless steel short pipe 3.

[0035] like Figures 1-5 As shown, both the stainless steel short pipe 3 and the external threaded connector 4 are made of stainless steel.

[0036] like Figures 1-5 As shown, the stainless steel short pipe 3 is made of stainless steel, and the external threaded connector 4 is made of synthetic plastic.

[0037] It should be noted that the connection between the external threaded connector 4 and the stainless steel short pipe 3 can be made using welding technology, and the area with the external thread can be made of different materials as needed.

[0038] Working principle: By adding a short pipe with an external threaded connector to the outside of the original double-press-fit half-connector, the independent double-press-fit half-connectors are connected together to form a three-dimensional tee fitting. This can achieve a three-dimensional flow diversion effect at the user's construction site. That is, the stainless steel double-press-fit half-connector A1, stainless steel double-press-fit half-connector B2 and stainless steel short pipe 3 of this tee form a 90° U-shaped structure. Its design is based on the principle of fluid mechanics: when the fluid enters one port of the tee, the flow direction of the fluid will change due to the 90° turning design. At the same time, this 90° turning design can accurately control the flow direction of the fluid, so that the fluid enters other branch pipes according to the preset pipe layout. That is, it enters the interior of the connected pipe through the external threaded connector 4, which meets the needs of complex pipe systems. For example, in the water supply and drainage system of a building, it can accurately guide the vertical water flow to the horizontal branch pipe to achieve three-dimensional turning. At the same time, the integrated structure avoids cumbersome operation during installation.
