Technical Field

[0001] The utility model relates to the technical field of three-way pipes, and particularly relates to a three-way pipe. Background Technique

[0002] A three-way pipe is a commonly used pipe fitting, mainly used for connecting three pipes in a pipe system. Its structure is in a "T" shape, with a main channel and two branch channels. The three-way pipe can be used for fluid transportation in different directions and is usually widely used in fields such as plumbing, heating, and gas transportation.

[0003] For example, a three-way pipe disclosed in the authorized publication number CN220286734U includes a main pipe body and a secondary pipe body. The main pipe body is fixedly connected to the upper side of the secondary pipe body. An installation part is provided on the main pipe body, and a protection cylinder is detachably connected inside the installation part. A filter element is detachably connected inside the protection cylinder. A spring is provided on one side of the protection cylinder, and a closing plate is detachably connected to the other side of the protection cylinder. The beneficial effect after adopting the above technical solution is that the filter element can filter the fluid, reduce the impurities in the fluid, effectively reduce the accumulation of impurities at the connection of the main pipe body and the secondary pipe body, and extend the service life of the main pipe body and the secondary pipe body.

[0004] Although the above patent can effectively reduce the accumulation of impurities at the connection of the main pipe body and the secondary pipe body, the impurities are intercepted at the upper end of the filter element and do not have a self-cleaning function. Therefore, it will cause blockage after long-term use, and the above problems can only be solved by frequently replacing the filter element, resulting in cost waste. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1-4 shown, a technical solution provided by the present invention:

[0027] A tee pipe includes a main pipeline 1. One end of the main pipeline 1 is integrally formed with an auxiliary pipeline 2. Both ends of the middle part of the main pipeline 1 are integrally formed with reversing valves 3. The same-side outer parts of the two reversing valves 3 are connected to an external connecting pipe 4. A direction adjustment mechanism is arranged inside the reversing valve 3. The direction adjustment mechanism includes a valve core 7. The valve core 7 is movably installed inside the reversing valve 3. One end of the valve core 7 penetrates through the reversing valve 3 and is fixedly connected to a knob 8. A diversion groove 9 is arranged inside the valve core 7. The diversion groove 9 is of a T-shaped structure, a sewage discharge pipe 6. The sewage discharge pipe 6 is arranged at the upper end of the same side of the main pipeline 1 close to the branch pipe 5. A plug 12 is arranged inside the sewage discharge pipe 6. The plug 12 is threadedly connected with the sewage discharge pipe 6;

[0028] In this embodiment, during use, impurities are intercepted at the upper position by the filter 10. Then, the knobs 8 on the outer sides of the two reversing valves 3 are turned in sequence. The knobs 8 control the rotation of the valve core 7, so that the diversion groove 9 connects the main pipeline 1 and the external connecting pipe 4. At this time, the water fed from the inlet end of the main pipeline 1 enters from the upper end of the external connecting pipe 4 and flushes the filter 10 through the lower end. Then, the plug 12 is removed, and the impurities accumulated at the upper end of the filter 10 will be discharged from the sewage discharge pipe 6. In this way, during cleaning, dirt is not easily dropped into the lower auxiliary pipeline 2, and there is no need to disassemble the filter 10 for cleaning.

[0029] As Figure 2 and Figure 3 shown, the branch pipe 5 is arranged in the middle of the main pipeline 1. A filtering mechanism is arranged inside the branch pipe 5. The filtering mechanism includes a filter 10. The filter 10 is movably installed inside the branch pipe 5. The other end of the filter 10 is fixedly connected to a cover 11. The cover 11 is threadedly connected to the outside of the branch pipe 5. The filter 10 is perpendicular to the main pipeline 1 in angle and parallel to the auxiliary pipeline 2 in angle. The filter 10 uses an activated carbon filter element;

[0030] In this embodiment, when in use, water enters from one end of the main pipe 1 away from the auxiliary pipe 2 and is filtered by the filter 10 inside the branch pipe 5. One end of the filter 10 is provided with a cover 11, and the cover 11 is threadedly connected to the outer side of the branch pipe 5. When the cover 11 is damaged, the filter 10 can be taken out and replaced by disassembly.

[0031] Working principle: When this device is in use, water enters from one end of the main pipe 1 away from the auxiliary pipe 2 and is filtered by the filter 10 inside the branch pipe 5. One end of the filter 10 is provided with a cover 11, and the cover 11 is threadedly connected to the outer side of the branch pipe 5. When the cover 11 is damaged, the filter 10 can be taken out and replaced by disassembly; in daily use, impurities are intercepted by the filter 10 at the upper end position, and then the knobs 8 on the outer sides of the two reversing valves 3 are turned in sequence. The knob 8 controls the rotation of the valve core 7, so that the diversion groove 9 connects the main pipe 1 and the external connection pipe 4. At this time, the water fed from the inlet end of the main pipe 1 enters from the upper end of the external connection pipe 4 and flushes the filter 10 through the lower end. Then, the plug 12 is removed, and the impurities accumulated at the upper end of the filter 10 will be discharged from the sewage pipe 6. In this way, when cleaning, dirt is not easily dropped into the lower auxiliary pipe 2, and it is not necessary to disassemble the filter 10 for cleaning.
