[0031] 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.

[0032] Reference Figures 1-3One embodiment of this utility model is an MPP pipe with a buffer mechanism, including a three-way pipe body 1. A fixing plate 2 is fixedly connected inside the three-way pipe body 1. The fixing plate 2 is located directly below the upper vertical pipe of the three-way pipe body 1. A base plate 3 is detachably connected to the upper end of the fixing plate 2. The base plate 3 and the parts set above it can be disassembled and can be directly replaced when severe wear occurs, avoiding the need to replace the entire MPP three-way pipe and thus avoiding resource waste.

[0033] Reference Figures 2-4 The bottom of the base plate 3 is provided with an installation unit, which includes a screw 31. The screw 31 is located at the rear end of the fixing plate 2. The upper surface of the fixing plate 2 is provided with a slot 32. The bottom end of the base plate 3 is fixedly connected with a plug 33. The plug 33 is inserted into the slot 32 and can be directly inserted and removed. The back of the plug 33 is provided with a screw hole 34. The front end of the screw 31 passes through the fixing plate 2 and is threadedly connected to the screw hole 34. In the initial state, the front end of the screw 31 is located inside the screw hole 34, which can fix the base plate 3 and the plug 33. When it is necessary to disassemble the base plate 3 and the parts set on it, the screw 31 can be turned out of the screw hole 34 to complete the disassembly operation, which is simple.

[0034] An elastic element 4 is fixedly connected to the upper surface of the base plate 3. A buffer plate 5 is fixedly connected to the top of the elastic element 4. When the buffer plate 5 moves downward, it can squeeze the elastic element 4, causing the elastic element 4 to compress and generate elastic potential energy. A buffer pad 6 is fixedly connected to the upper surface of the buffer plate 5. The buffer pad 6 can buffer the water flow flowing down through the upper vertical pipe. When impacted by the water flow, the buffer pad 6 and the buffer plate 5 will move downward to squeeze the elastic element 4. The elastic potential energy generated by the elastic element 4 will further buffer the water flow, preventing the water flow from causing wear at the junction of the inner walls of the pipe body during movement, thus affecting the service life of the pipe body. The front and rear ends of the buffer plate 5 and the buffer pad 6 are inclined downward. The outer wall of the buffer pad 6 is in contact with the inner wall surface of the tee pipe body 1. When the water flow impacts the surface of the buffer pad 6, it can be diverted along the inclined surfaces on the left and right sides of the buffer pad 6, allowing the water flow to flow better to the left and right channels, further reducing the impact wear at the junction of the inner walls of the pipe body.

[0035] A protective unit is provided on the outer side of the buffer plate 5. The protective unit includes a triangular plate 61, which is fixedly connected to the upper end of the buffer pad 6. The triangular plate 61 can break the downward flow of water, allowing the water to flow better to both sides. An annular filter cloth 62 is fixedly connected to the upper end of the fixed plate 2. The annular filter cloth 62 is sleeved on the outer side of the elastic member 4. The upper end of the annular filter cloth 62 is fixedly connected to the bottom surface of the buffer plate 5. The annular filter cloth 62 can filter the gap between the fixed plate 2 and the buffer plate 5, preventing impurities in the water flow from entering the gap and adhering to the surface of the elastic member 4, which would cause scale to form on the surface of the elastic member 4 and affect the buffering performance of the elastic member 4.

[0036] Reference Figure 2 and Figure 5 A fixing ring 7 is fixedly connected to the upper end of the three-way pipe body 1. A threaded groove 8 is opened on the inner wall surface of the fixing ring 7. A threaded cylinder 9 is threadedly connected to the inside of the fixing ring 7 through the threaded groove 8. When the threaded cylinder 9 is turned, it can be disengaged from the inside of the fixing ring 7. A filter plate 10 is fixedly connected to the upper end of the threaded cylinder 9. When the filter plate 10 rotates, it can drive the threaded cylinder 9 to move synchronously. The outer wall of the filter plate 10 is in contact with the inner wall surface of the three-way pipe body 1, and the bottom surface of the filter plate 10 is in contact with the upper surface of the fixing ring 7. The filter plate 10 can perform complete preliminary filtration of the water flowing downward through the upper end of the three-way pipe body 1, so as to prevent large impurities in the water flow from hitting the triangular plate 61 and affecting the service life of the protection unit. A handle 11 is fixedly connected to the upper end of the filter plate 10. The operator can quickly and easily turn the filter plate 10 through the handle 11 for easy disassembly and cleaning.

[0037] Working principle: When water flows through the three-way pipe 1 for diversion, the water flows through the filter plate 10 after passing the upper end of the three-way pipe 1 for preliminary filtration, filtering out larger impurities in the water flow. Then the water flow continues to flow downwards to the triangular plate 61 and the buffer pad 6 for diversion, allowing the water flow to be guided to both sides, avoiding the water flow from directly impacting the confluence of the inner wall of the pipe. At the same time, the buffer pad 6 and the elastic element 4 can buffer the impact force of the water flow, further reducing the impact of the water flow on the pipe body and extending the service life of the MPP three-way pipe. When the buffer pad 6 and the elastic element 4 are severely worn after a period of use and need to be replaced, the screw 31 can be unscrewed to release the fixation of the base plate 3, and the parts above the base plate 3 can be quickly disassembled and replaced, which is simple and quick.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
