Description

Technical Field

[0001] The utility model relates to a sleeve type cleaning tee, belonging to the field of pipe fittings. Background Art

[0002] A pigging tee is a three-way pipe fitting that can achieve normal medium diversion and ensure the smooth passage of the pig. After the existing gas pipeline is constructed, it is necessary to clean the construction impurities in the pipeline; after the pipeline has been running for a period of time, it is also necessary to clean the impurities and accumulated liquid in the pipeline. Welding a retaining bar inside the branch pipe on the tee is one of the ways to prevent the pigging ball from getting stuck at the tee. Because the internal space of the branch pipe is small, welding the retaining bar on the inner wall of the branch pipe is difficult due to insufficient operating space. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a sleeve type cleaning tee to solve the problems raised in the above-mentioned background technology. The utility model adopts an assembly method to install the structure of preventing the cleaning ball from getting stuck in the tee pipe fitting in the branch pipe, thereby reducing the difficulty of assembly.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a sleeve type pipe cleaning tee, comprising a main pipe, a branch pipe communicating with the main pipe is installed on the outer surface of the main pipe, a hollow pipe arranged concentrically with the branch pipe is inserted in the branch pipe, an end of the hollow pipe close to the main pipe is connected and fixed with an arc plate, the arc plate is arranged at the contact position between the main pipe and the branch pipe, the hollow pipe passes through the arc plate, a plurality of water holes are evenly opened on the outer surface of the arc plate, a plurality of connecting rods are fixed on the outer surface of the upper end of the branch pipe in an annular shape at equal intervals, an end of the connecting rod away from the branch pipe is fixed on the inner wall of the connecting ring, a docking ring is provided on the side of the connecting ring facing the branch pipe, the docking ring is sleeved on the branch pipe and connected and fixed to the branch pipe, a plurality of second small holes are evenly opened on the side of the docking ring facing the connecting ring, and a plurality of first small holes aligned with the second small holes are evenly opened on the side of the connecting ring facing the docking ring.

[0005] Furthermore, a pipe sleeve is provided on the hollow tube, and a positioning screw for limiting the relative position of the pipe sleeve and the hollow tube is threadedly connected to the outer surface of the pipe sleeve, and the pipe sleeve is fixed in the middle position of one side of the mesh disk, and the mesh disk is provided on the hollow tube and the mesh disk is slidably installed in the branch pipe, and a plurality of conical rods for inserting in the water holes are evenly fixed on the side of the mesh disk away from the pipe sleeve.

[0006] Furthermore, one end of the main pipe is sleeved with a first end ring connected and fixed to the main pipe, and a side surface of the first end ring is provided with a plurality of first through holes for inserting bolts at equal intervals in a circular shape.

[0007] Furthermore, one end of the main pipe away from the first end ring is sleeved with a second end ring connected and fixed to the main pipe, and a side surface of the second end ring is provided with a plurality of second through holes for inserting bolts at equal intervals in a circular shape.

[0008] Furthermore, a through hole is provided at the position where the arc-shaped plate is mounted with the hollow tube, and one end of the hollow tube is fixed in the through hole.

[0009] Furthermore, a side of the connecting ring facing away from the docking ring is recessed to form a first sealing groove for storing a sealing ring, and a side of the connecting ring facing away from the first sealing groove is recessed to form a second sealing groove for storing a sealing ring.

[0010] Beneficial effects of the utility model:

[0011] 1. Insert the hollow pipe into the branch pipe so that the butt ring fits the connecting ring. At this time, the arc plate used to limit the position of the pigging ball is at the connection between the branch pipe and the main pipe. After the butt ring and the connecting ring are connected by bolts, the position of the arc plate is restricted. The arc plate that prevents the pigging ball from getting stuck in the tee pipe fitting is installed in the branch pipe by assembly, which reduces the difficulty of assembly.

[0012] 2. After the hollow pipe and the branch pipe are assembled, a sleeve structure is formed, and the hollow pipe and the water holes on the arc plate jointly achieve the purpose of water flow.

[0013] 3. Adjust the position of the mesh disk so that the length of the tapered rod on the mesh disk inserted in the water hole changes. Because the diameter of the tapered rod gradually decreases in the direction away from the mesh disk, after the tapered rod is inserted in the water hole, the water flow channel in the water hole changes. At this time, the tapered rod and the arc plate work together to play a filtering role. BRIEF DESCRIPTION OF THE DRAWINGS

The arc plate 13 is arranged at the contact position between the main pipe 1 and the branch pipe 9. A through hole is opened at the position where the hollow tube 5 is installed on the arc plate 13, wherein one end of the hollow tube 5 is fixed in the through hole, and a plurality of water holes 14 are evenly opened on the outer surface of the arc plate 13. A plurality of connecting rods 6 are fixed in an annular shape and at equal intervals on the outer surface of the upper end of the branch pipe 9. The end of the connecting rod 6 away from the branch pipe 9 is fixed on the inner wall of the connecting ring 10. A docking ring 4 is provided on the side of the connecting ring 10 facing the branch pipe 9. The docking ring 4 is sleeved on the branch pipe 9 and connected and fixed to the branch pipe 9. The side of the docking ring 4 facing the connecting ring 10 is evenly opened. A plurality of second small holes 12 are provided, and a plurality of first small holes 11 which are aligned with the second small holes 12 are evenly provided on one side of the connecting ring 10 facing the docking ring 4. The hollow pipe 5 is inserted into the branch pipe 9 so that the docking ring 4 fits the connecting ring 10. At this time, the arc plate 13 for limiting the position of the cleaning ball is located at the connection portion between the branch pipe 9 and the main pipe 1. After the docking ring 4 and the connecting ring 10 are connected by bolts, the position of the arc plate 13 is limited, and the arc plate 13 is installed in the branch pipe 9 to prevent the cleaning ball from being stuck in the tee pipe fitting by assembling, thereby reducing the difficulty of assembly.
