Description

Technical Field

[0001] This utility model belongs to the field of tee fittings, specifically, it relates to a tee fitting with a filtering function that is easy to connect. Background Technology

[0002] In the piping systems of refrigeration equipment, tee fittings are commonly used pipe connection accessories, serving to distribute refrigerant.

[0003] Patent application CN215908629U discloses a tee connector with a filtering function. Paragraph 0027 of the specification discloses that the filtering assembly includes a fixed ring plate and a filter perforated plate. The fixed ring plate is disposed on the inner wall of the tee connector body. The filter perforated plate can block large particulate impurities in the fluid from passing through, avoiding pipe blockage. The filter perforated plate has connecting grooves distributed opposite each other. The connecting groove includes a limiting arc-shaped groove and an installation groove. The installation groove communicates with the limiting arc-shaped groove, and the cross-sectional diameter of the installation groove is larger than that of the limiting arc-shaped groove. The fixed ring plate is provided with a fixing pin corresponding to the limiting arc-shaped groove. The fixing pin is provided with a fixing end corresponding to the installation groove. The fixing end restricts the fixing pin from disengaging from the limiting arc-shaped groove, realizing a detachable connection between the fixed ring plate and the filter perforated plate.

[0004] In actual use, the following defects were found: the fixing pin needs to be rotated from the mounting slot into the limiting arc groove in order to position the filter plate in the fixing ring plate. However, since there is no force application point on one side of the filter plate, it is difficult to drive it to rotate on the side of the fixing ring plate, which makes it impossible to quickly disassemble the filter plate, thus affecting its cleaning and replacement.

[0005] To address these shortcomings, a tee with filtering function that is easy to connect is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a tee with a filtering function that is easy to connect.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A tee with a filtering function that is easy to connect includes a main pipe, a branch pipe connected and communicated with the main pipe, and a placement groove is provided on the inner side wall of one end of the main pipe and the inner side walls of both ends of the branch pipe. A filter plate and a positioning component that cooperates with the filter plate are placed inside the placement groove.

[0009] The positioning assembly includes an annular plate threaded into a placement groove, with multiple grooves on the inner sidewall of the annular plate, and one end of the annular plate located on one side of the filter plate.

[0010] Optionally, annular columns are provided on the outer wall of one end of the main pipe and the outer walls of both ends of the branch pipe, and sealing caps are provided on the annular columns. The sealing caps are located on the main pipe and the branch pipe.

[0011] Optionally, a sealing ring is provided on the outer wall of one end of the main pipe and the outer walls of both ends of the branch pipe, and the sealing ring is located inside the annular column.

[0012] Optionally, a reinforcing block is provided between the branch pipe and the main pipe. The reinforcing block is provided with two extended reinforcing bars, which are fixed to the main pipe and the branch pipe respectively. One end of the extended reinforcing bars is fixed to the annular column.

[0013] Optionally, two guide rods are provided in the placement groove, and two positioning holes are opened on the filter plate. The guide rods are located in the positioning holes, and one end of the guide rod is located on one side of the annular plate.

[0014] Optionally, a first sealing gasket and a second sealing gasket are respectively provided on both sides of the filter plate. The first sealing gasket has two first through holes, and the guide rod is located in the first through hole. The second sealing gasket has two second through holes, and the guide rod is located in the second through hole.

[0015] Optionally, the groove is provided with an internal thread, and the outer wall of the annular plate is provided with an external thread, with the external thread engaging with the internal thread.

[0016] Optionally, a fixed column is installed inside the branch pipe, and a ball is installed on the fixed column. One end of the main pipe and both ends of the branch pipe are provided with constricted ends.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0018] The filter plate is positioned by a guide rod and locked by a threaded ring plate, allowing for quick disassembly, cleaning, or replacement without tools, reducing the cumbersome maintenance of the filter device. The first and second sealing gaskets placed in the groove cooperate with the ring plate to ensure no leakage at the edge of the filter plate. The sealing rings and sealing caps at the ends of the main and branch pipes combine to achieve airtightness at the pipe connections, reducing the problem of fluid leakage or foreign object intrusion.

[0019] Sealing rings are installed on the outer walls of the annular columns at the ends of the main pipe and branch pipe. When the annular column is inserted into the external pipe interface, the sealing ring is squeezed and deformed, filling the gap between the annular column and the inner wall of the external pipe to form a seal, reducing fluid leakage from the connection. The guide rod in the placement groove is inserted into the positioning hole of the filter plate and passes through the first through hole of the first sealing gasket and the second through hole of the second sealing gasket, aligning the filter plate, the first sealing gasket, the second sealing gasket with the axis of the placement groove, reducing sealing failure caused by installation misalignment. The reinforcing block connects the angled area between the main pipe and the branch pipe, and the extended reinforcing ribs on both sides are fixed to the branch pipe, the main pipe and the annular column respectively, forming a triangular support structure. When the fluid in the pipe generates pressure or external force is applied, the extended reinforcing ribs disperse the applied force from the connection between the main pipe and the branch pipe to the annular column, reducing cracking or deformation caused by concentrated force and improving the overall pressure resistance of the tee.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figure 1-4 As shown, this embodiment provides a tee with a filtering function that is easy to connect, including a main pipe 1, a branch pipe 2 connected and communicated on the main pipe 1, and a placement groove 8 is provided on the inner side wall of one end of the main pipe 1 and the inner side walls of both ends of the branch pipe 2. A filter plate 14 and a positioning component that cooperates with the filter plate 14 are placed inside the placement groove 8.

[0031] The positioning assembly includes an annular plate 18 threaded into the placement groove 8. The inner sidewall of the annular plate 18 has multiple grooves 19, and one end of the annular plate 18 is located on one side of the filter plate 14.

[0032] Specifically, the filter plate 14 is placed in the placement groove 8 at the ends of the main pipe 1 and the branch pipe 2, and a seal is formed by the first sealing gasket 12 and the second sealing gasket 16 on both sides. The guide rod 11 in the placement groove 8 is inserted into the positioning hole 15 of the filter plate 14 to ensure accurate alignment of the filter plate 14 and reduce misalignment. By rotating the annular plate 18, the external thread of its outer wall engages with the internal thread of the placement groove 8, causing the annular plate 18 to move axially. The groove 19 on the inner wall presses against the edge of the filter plate to achieve fixation. At this time, one end of the annular plate 18 abuts against one side of the filter plate 14, cooperating with the first sealing gasket 12 and the second sealing gasket 16 on both sides. 2. The second sealing gasket 16 forms a reliable seal, reducing fluid leakage from the edge of the filter plate 14. When the fluid flows through the main pipe 1 or branch pipe 2, it first filters impurities through the sieve holes of the filter plate 14. The impurities are trapped on one side of the filter plate 14, and the clean fluid continues to flow through the filter plate 14. The annular post 9 at the end of the main pipe 1 and branch pipe 2 can be inserted into the external pipe interface and form a seal with the inner wall of the external pipe through the sealing ring 7, reducing leakage at the connection. The reinforcing block 3 and reinforcing rib 4 between the main pipe 1 and branch pipe 2 enhance the overall structural strength of the tee and reduce the breakage at the connection due to fluid pressure or external force.

[0033] The filter plate 14 is positioned by the guide rod 11 and locked by the threaded annular plate 18, which allows for quick disassembly, cleaning or replacement without tools, reducing the cumbersome maintenance of the filter device. The first sealing gasket 12 and the second sealing gasket 16 placed in the groove 8 cooperate with the annular plate 18 to ensure no leakage at the edge of the filter plate 14. The sealing ring 7 at the end of the main pipe 1 and the branch pipe 2 are combined with the sealing cap 10 to achieve airtightness at the pipe connection, reducing the problem of fluid leakage or foreign object intrusion.

[0034] like Figure 1-4As shown, in this embodiment, annular columns 9 are provided on the outer side wall of one end of the main pipe 1 and the outer side walls of both ends of the branch pipe 2. Sealing caps 10 are provided on the annular columns 9, located on the main pipe 1 and the branch pipe 2. Sealing rings 7 are provided on the outer side wall of one end of the main pipe 1 and the outer side walls of both ends of the branch pipe 2, located inside the annular columns 9. A reinforcing block 3 is provided between the branch pipe 2 and the main pipe 1. Two extending reinforcing ribs 4 are provided on the reinforcing block 3, respectively fixed to the main pipe 1 and the branch pipe 2. One end of each extending reinforcing rib 4 is fixed to the annular column 9. Two guide rods 11 are provided in the placement groove 8. The filter plate 14... Two positioning holes 15 are provided, and the guide rod 11 is located in the positioning holes 15. One end of the guide rod 11 is located on one side of the annular plate 18. A first sealing gasket 12 and a second sealing gasket 16 are respectively provided on both sides of the filter plate 14. Two first through holes 13 are provided on the first sealing gasket 12, and the guide rod 11 is located in the first through hole 13. Two second through holes 17 are provided on the second sealing gasket 16, and the guide rod 11 is located in the second through hole 17. An internal thread is provided on the groove 19, and an external thread is provided on the outer wall of the annular plate 18. The external thread and the internal thread are threaded together. A fixing post is provided in the branch pipe 2, and a ball is provided on the fixing post.

[0035] Sealing rings 7 are provided on the outer walls of the annular columns 9 at the ends of the main pipe 1 and the branch pipe 2. When the annular column 9 is inserted into the external pipe interface, the sealing ring 7 is squeezed and deformed, filling the gap between the annular column 9 and the inner wall of the external pipe to form a seal, reducing fluid leakage from the connection. The guide rod 11 in the placement groove 8 is inserted into the positioning hole 15 of the filter plate 14, and passes through the first through hole 13 of the first sealing gasket 12 and the second through hole 17 of the second sealing gasket 16, so that the filter plate 14, the first sealing gasket 12, the second sealing gasket 16 are aligned with the axis of the placement groove 8, reducing the sealing failure caused by installation misalignment. The reinforcing block 3 connects the angle area between the main pipe 1 and the branch pipe 2. The extended reinforcing ribs 4 on both sides are fixed to the branch pipe 2, the main pipe 1 and the annular column 9 respectively, forming a triangular support structure. When the fluid in the pipe generates pressure or external force is applied, the extended reinforcing ribs 4 disperse the applied force from the connection between the main pipe 1 and the branch pipe 2 to the annular column 9, reducing cracking or deformation caused by concentrated applied force and improving the overall pressure resistance of the tee.
