Description

Technical Field

[0001] This utility model relates to the field of drainage diversion technology, and in particular to a water supply and drainage diversion device. Background Technology

[0002] Water supply and drainage is the supply of domestic and industrial water for residents, factories, mines, and transportation companies. Water supply and drainage diversion is the process of guiding different types or qualities of water to different pipelines through diversion devices, so that the water is directed to different systems for treatment, thereby improving the treatment efficiency of the water supply and drainage system and making it more conducive to the reuse of resources.

[0003] Currently, existing water supply and drainage diversion devices, such as Chinese Patent Publication No. CN220814143U, disclose a diversion device for water supply and drainage, including a diversion box with a cover at the top and three diversion pipes on the outside. A cleaning component is installed at the top of the cover, and a main flow pipe is installed on the outside of the diversion box. An inlet pipe is installed on one side of the main flow pipe through two sets of flanges. An adjustment component is installed inside the inlet pipe, and a filter screen is installed between the two sets of flanges. A reinforcing rod is installed on the outside of the diversion box. In order to connect flanges one and two to the diversion box and the main flow pipe respectively by bolts and avoid turbulent water supply and drainage during the diversion process, flange two is installed on one side of the diversion pipe. Bolts are installed on one side of flanges one and two. The flanges can drive a scraper to rotate through a turntable to scrape off the scale inside the diversion box and prevent scale accumulation due to long-term water flow. However, the above device has a complex structure and is cumbersome to operate, and is not suitable for some pipeline systems with low internal liquid pressure.

[0004] How to quickly and easily switch the direction of liquid flow, save operation time, and achieve a simple structure that is easy to control has become a technical problem that needs to be solved.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] In view of the above-mentioned defects, the purpose of this utility model is to provide a water supply and drainage diversion device that can quickly switch the liquid flow direction at any time, save operation time, and has a simple structure and is easy to control.

[0007] To achieve the above objectives, this utility model provides a water supply and drainage diversion device, including a housing.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] See Figures 1-3This utility model provides a water supply and drainage diversion device, including a housing 1, which is hollow inside. One end of the housing 1 is connected to an inlet pipe 11, and the other end is connected to a first outlet pipe 12 and a second outlet pipe 13. A longitudinally arranged first flow channel 14 is provided between the inlet pipe 11 and the first outlet pipe 12 inside the housing 1. A transversely arranged second flow channel is provided between the second outlet pipe 13 and the inlet pipe 11 and the first outlet pipe 12 inside the housing 1. The first flow channel 14 and the second flow channel are interconnected. The diameter of the first flow channel 14 is smaller than the diameter of the second flow channel. A switching pipe 2 is slidably arranged inside the second flow channel. The switching pipe 2 is hollow, and an opening is provided on the side of the switching pipe 2 near the second outlet pipe 13. The switching pipe 2 and the second flow channel are slidably sealed. One end of the switching pipe 2 is connected to an extension rod 22, and one end of the extension rod 22 extends out of the outer shell 1. The outer shell 1 has a clearance space that allows the extension rod 22 to move. Pushing the extension rod 22 can move the switching pipe 2. The switching pipe 2 has a hollow groove 21. When the switching pipe 2 is located inside the second flow channel, the inlet pipe 11 and the first outlet pipe 12 are connected to each other. When one end of the switching pipe 2 moves into the first flow channel 14, the inlet pipe 11 and the second outlet pipe 13 are connected to each other.

[0025] See Figures 1-3 Preferably, the first flow channel 14 is provided with a receiving groove 141 that cooperates with the switching pipe 2. When one end of the switching pipe 2 moves into the first flow channel 14, the receiving groove 141 can better wrap the switching pipe 2 and improve the sealing effect between the first flow channel 14 and the switching pipe 2.

[0026] See Figures 1-3 The outer shell 1 is symmetrically equipped with limiting blocks 3. The friction between the limiting blocks 3 and the outer shell 1 is large. When there is no external interference, the limiting blocks 3 will not slide arbitrarily. When the switching tube 2 is located inside the second flow channel, the two limiting blocks 3 abut against each other. This not only blocks the clearance space to prevent external impurities from entering the outer shell 1, but also restricts the position of the extension rod 22 to prevent the extension rod 22 from sliding.

[0027] See Figures 1-3 Preferably, each of the two limiting blocks 3 is provided with a magnet at one end that is close to each other, so that when the two limiting blocks 3 come into contact with each other, the limiting blocks 3 are further prevented from moving.

[0028] See Figures 1-3A positioning rod 4 is provided on the outer shell 1, with one end of the positioning rod 4 protruding out of the outer shell 1 and elastically connected to the outer shell 1 (the positioning rod 4 inside the outer shell 1 is symmetrically provided with inserts, and the outer shell 1 is provided with slots that cooperate with the inserts, the inserts are all slidably set in the slots, and elastic elements 5 are provided between the inserts and the slots). The switching tube 2 is provided with a positioning groove 23 that cooperates with the positioning rod 4. When one end of the switching tube 2 moves into the first flow channel 14, the positioning rod 4 and the positioning groove 23 cooperate with each other to prevent the switching tube 2 from moving. Pulling the positioning rod 4 away from the switching tube 2 will disengage the positioning rod 4 from the positioning groove 23.

[0029] See Figures 1-3 Preferably, the elastic element 5 is a spring, which provides return power.

[0030] See Figures 1-3 Connect the outer casing 1 vertically to the pipeline (see direction). Figure 1 or Figure 2 When the liquid in the inlet pipe 11 needs to flow to the first outlet pipe 12, push the extension rod 22 to move the switching pipe 2 into the second flow channel, so that the two limiting blocks 3 abut against each other, thus connecting the inlet pipe 11 and the first outlet pipe 12. When the liquid in the inlet pipe 11 needs to flow to the second outlet pipe 13, push the extension rod 22 to move one end of the switching pipe 2 into the first flow channel 14, so that the positioning rod 4 and the positioning groove 23 cooperate with each other, thus connecting the inlet pipe 11 and the second outlet pipe 13. The liquid in the inlet pipe 11 can flow out from the second outlet pipe 13 after passing through the hollow groove 21 and the switching pipe 2.

[0031] This utility model provides a water supply and drainage diversion device, including a housing. By moving the switching pipe inside the housing, the liquid flow direction can be switched quickly and easily, saving operation time. The two limiting blocks abut against each other, not only sealing off the clearance space to prevent external impurities from entering the housing, but also restricting the position of the extension rod to prevent it from sliding. The positioning rod and positioning groove cooperate to prevent the switching pipe from moving. In summary, the advantages of this utility model are: it can quickly and easily switch the liquid flow direction, saving operation time, and its structure is simple and easy to control.

[0032] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
