Description

Technical Field

[0001] This utility model relates to the field of three-way valve technology, specifically a reducing four-way pipe. Background Technology

[0002] A four-way pipe connector has four connecting pipes, which are fixedly arranged in a cross shape. In actual use, the pipes to be connected may not perfectly match the cross shape of the four-way connector. For example, the two pipes to be connected may be on the same side of the main water pipe, or the two pipes may have different angles or directions. Existing four-way pipe connectors cannot change the installation direction and angle, making installation relatively troublesome. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a reducing four-way pipe to solve the problem that the current four-way pipe cannot adjust the direction and angle.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A reducing four-way pipe includes a main pipe with two annular grooves and through holes communicating with the interior of the main pipe. A collar is rotatably connected to the annular grooves via a rotary bearing. The inner wall of the collar has an annular cavity communicating with the interior of the main pipe via the through holes. Sealing components are provided on both sides of the annular cavity inside the collar. The outer wall of the collar has a connecting hole communicating with the annular cavity. A first connecting pipe is threaded into the connecting hole. A bellows is connected to the outer end of the first connecting pipe. A second connecting pipe is connected to the outer end of the bellows. Connecting plates are fixedly connected to both the front and rear sides of the first connecting pipe on the collar. Shafts are fixedly connected to both the front and rear sides of the second connecting pipe. The shafts are rotatably connected to the two connecting plates.

[0006] Preferably, the sealing assembly includes a sealing groove formed in the annular groove and located on both sides of the through hole, and a plurality of toothed grooves formed in the annular groove and located on the outside of the sealing groove. The sealing assembly also includes a sealing strip connected to the inner wall of the collar and located on both sides of the annular cavity, and a toothed strip disposed on the inner wall of the collar and meshing with the toothed grooves. The sealing strip is movably disposed in the sealing groove.

[0007] In the above technical solution, the sealing strip is inserted into the sealing groove, and the rack meshes with the rack in the groove. Through the cooperation of the sealing strip and the multi-layer rack, the sealing performance between the collar and the annular groove can be improved, preventing liquid leakage.

[0008] Preferably, the shaft is provided with a first external thread on the outer wall of the connecting plate, and two nuts are connected through the first external thread. By tightening the two nuts, the two nuts are pressed tightly against both sides of the connecting plate to fix the shaft.

[0009] The above technical solution allows the shaft to be rotated by loosening the nut, thereby adjusting the angle of the second connecting pipe. Once the second connecting pipe is adjusted to the desired position, the nut can be tightened.

[0010] Preferably, the outer wall of the second connecting pipe is provided with a second external thread.

[0011] The above technical solution allows for the connection of an external pipe to the second connecting pipe via the second external thread.

[0012] Preferably, the two ends of the main tube are connected to a third connecting pipe, and the outer wall of the third connecting pipe is provided with a third external thread.

[0013] The above technical solution allows for the connection of external pipelines via two third connecting pipes and their third external threads.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Rotating the collar adjusts the horizontal orientation of the second connecting pipe, allowing it to connect to external pipes in different directions. Moving the second connecting pipe up and down adjusts its vertical angle, enabling it to connect to external pipes at different angles. This significantly improves the safety and convenience of pipework. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 A reducing four-way pipe includes a main pipe 1 with two annular grooves 2. Each annular groove 2 has a through hole 3 communicating with the interior of the main pipe 1. A collar 5 is rotatably connected to the annular grooves 2 via a rotary bearing 4. The inner wall of the collar 5 has an annular cavity 6, which communicates with the interior of the main pipe 1 through the through hole 3. The outer wall of the collar 5 has a connecting hole communicating with the annular cavity 6. A first connecting pipe 7 is threaded into the connecting hole. A corrugated pipe 8, made of PE corrugated pipe, is connected to the outer end of the first connecting pipe 7. The corrugated structure greatly enhances the ring stiffness of the pipe, enabling it to withstand large soil loads and ground traffic loads while maintaining a certain degree of bending flexibility. A second connecting pipe 9 is connected to the outer end of the corrugated pipe 8. The outer wall of the second connecting pipe 9 has a second external thread, through which an external pipe can be connected. Connecting plates 10 are fixedly connected to both the front and rear sides of the first connecting pipe 7 on the collar 5. Shafts 11 are fixedly connected to both the front and rear sides of the second connecting pipe 9, and the shafts 11 are rotatably connected to the two connecting plates 10.

[0024] Rotating the collar 5 adjusts the horizontal orientation of the second connecting pipe 9. Since the annular cavity 6 within the collar 5 communicates with the main pipe 1 through the through hole 3, and the first connecting pipe 7 communicates with the annular cavity 6, the first connecting pipe 7 remains connected to the main pipe 1 regardless of the rotation of the collar 5, allowing the second connecting pipe 9 to connect to external pipes in different directions. By moving the second connecting pipe 9 up and down, the vertical angle of the second connecting pipe 8 can be adjusted, thus connecting to external pipes at different angles. This significantly improves the safety and convenience of the pipeline system.

[0025] The shaft 11 has a first external thread on its outer wall outside the connecting plate, and two nuts 16 are connected to it through the first external thread. Tightening the two nuts 16 will press them tightly against both sides of the connecting plate 10, thus fixing the shaft 11. Loosening the nuts 16 allows the shaft 11 to rotate, thereby adjusting the angle of the second connecting tube 9. Once the second connecting tube 9 is adjusted to the desired position, tightening the nuts 16 will stabilize the second connecting tube 9.

[0026] The collar 5 is provided with sealing components on both sides of the annular cavity 6. Each sealing component includes a sealing groove 12 formed within the annular groove 2 and located on both sides of the through hole 3, and several toothed grooves 13 formed within the annular groove 2 and located outside the sealing groove 12. The sealing component also includes a sealing strip 14 connected to the inner wall of the collar 5 and located on both sides of the annular cavity 6, and a rack 15 disposed on the inner wall of the collar 5 and meshing with the toothed grooves 13. Both the sealing groove 12 and the sealing strip 14 are annular, with the sealing strip 14 movably disposed within the sealing groove 12. The toothed grooves 13 and the rack 15 are annular, and the toothed grooves 13 and racks 15 are parallel to each other. The sealing strip 14 is engaged within the sealing groove 12. When the collar 5 rotates, the sealing strip 14 rotates within the sealing groove 12, while the rack 15 rotates within the toothed grooves 13. Multiple sets of these racks further improve sealing performance. By combining sealing strips and multi-layer toothed racks, the sealing performance between the collar and the annular groove can be improved, preventing liquid leakage.

[0027] The main pipe 1 is connected to three connecting pipes 17 at both ends, and the outer wall of the three connecting pipes 17 is provided with a third external thread. External pipes can be connected through the two third connecting pipes and their third external threads.

[0028] The main pipe, collar, first connecting pipe, second connecting pipe, and connecting plate of this utility model are all made of stainless steel, which extends the service life.
