[0028] From the above description, it can be seen that the beneficial effects of the present invention are: providing a one-way dosing pipe for water quality regulation in a water supply pipeline, designing an independent one-way screw sleeve 1 structure, opening a dosing hole 11 on the screw sleeve 1, and embedding a one-way valve core 2 in the dosing hole 11 to achieve one-way conduction, and a detachable connection is adopted between the screw sleeve 1 and the water supply pipeline and between the water supply pipeline. Compared with the traditional dosing method, it has the advantages of easy disassembly and assembly, easy maintenance and good flexibility.

[0029] In an optional embodiment, the screw sleeve 1 includes a sleeve body 12 and a sleeve cover 13, the sleeve body 12 is provided with the dosing hole 11 from one end to the other end, one end of the sleeve body 12 is threadedly engaged with the sleeve cover 13, the sleeve cover 13 is provided with a first through hole 131 for the connecting pipe 3 to pass through, and the connecting pipe 3 is snap-fitted with the sleeve cover 13.

[0030] From the above description, it can be known that the sleeve body 12 and the sleeve cover 13 are quickly assembled through threaded cooperation. After the pipe 3 is connected, it is fixed by snapping with the sleeve cover 13 to achieve communication with the medicine injection hole 11 in the sleeve body 12, so as to input the medicine.

[0031] In an optional embodiment, the other end of the sleeve body 12 is provided with a threaded connection portion 121 for connecting to a water supply pipe.

[0032] From the above description, it can be known that the threaded connection portion 121 can be directly matched with the thread of the water supply pipe, or can be connected to the water supply pipe through the nut of the connecting pipe 3 to achieve quick disassembly and assembly.

[0033] In an optional embodiment, the screw sleeve 1 also includes a clamp 14 and a joint 15, and the clamp 14 and the joint 15 are both pressed between the sleeve body 12 and the sleeve cover 13. The clamp 14 is provided with a second through hole 141 for the connecting pipe 3 to pass through. After the connecting pipe 3 passes through the second through hole 141, it is pressed between the clamp 14 and the joint 15. The joint 15 is provided with a third through hole 151 connecting the connecting pipe 3 and the medication hole 11.

[0034] From the above description, it can be seen that the connecting pipe 3 is clamped and fixed between the clamp head 14 and the connector 15 by the cooperation between the two, so as to realize the connection between the connecting pipe 3, the second through hole 141, the third through hole 151 and the dosing hole 11, with good stability and strong reliability.

[0035] In an optional embodiment, an annular sealing ring 4 is provided between the joint 15 and the sleeve body 12 .

When the medicine in the connecting pipe 3 passes through the fourth through hole 211 and the fifth through hole 221 in sequence and flows into the normally closed channel 222, the normally closed channel 222 is opened by the medicine.

[0038] From the above description, it can be seen that the valve core body 21 and the valve core rubber part 22 are nested and matched. When the medicine flows from the connecting pipe 3 to the water supply pipe, the medicine can stretch and deform the closed valve core rubber part 22 to form a channel after passing through the fifth through hole 221, but the medicine cannot flow directly from the water supply pipe to the connecting pipe 3 to stretch the normally closed channel 222 of the valve core rubber part 22, thereby realizing a unidirectional conductive structure.

[0039] In an optional embodiment, a stopper 5 is further included, wherein the stopper 5 is connected to the other end of the screw sleeve 1 , the stopper 5 abuts against the valve core rubber component 22 , and the stopper 5 is provided with a sixth through hole 51 , and the medicine flowing out of the normally closed channel 222 flows into the sixth through hole 51 .

[0040] From the above description, it can be known that the stopper 5 is used to seal the valve core rubber part 22, thereby preventing it from falling off from the screw sleeve 1, which ensures the structural stability on the one hand and improves the sealing performance between the components on the other hand.

[0041] In an optional embodiment, the stop member 5 includes a stop sleeve 52 and a limit nut 53, the stop sleeve 52 abuts against the valve core rubber part 22 and the limit nut 53 respectively, the limit nut 53 is threadedly matched with the other end of the threaded sleeve 1, and the stop sleeve 52 and the limit nut 53 are both provided with the sixth through hole 51.

[0042] It can be known from the above description that the stopper sleeve 52 is used to seal the valve core rubber component 22, and the limit nut 53 is used to support and fasten the stopper sleeve 52, so as to ensure the stability and sealing of the assembly structure.

[0043] In an optional embodiment, the other end of the threaded sleeve 1 is provided with an internal thread 16 , and the limiting nut 53 is provided with an external thread 531 matching with the internal thread 16 .

[0044] It can be seen from the above description that the threaded sleeve 1 and the limiting nut 53 are threadedly matched, which facilitates disassembly, replacement and inspection and maintenance of the components.

[0045] In an optional embodiment, the screw sleeve 1 is made of polypropylene.

[0046] From the above description, it can be seen that the screw sleeve 1 is made of polypropylene material and has good elasticity, corrosion resistance and aging resistance.

[0047] The working principle of the present invention is: during installation, one end of the connecting pipe 3 is inserted into the cover 13 and the body 12, and the connecting pipe 3 is clamped and fixed by the clamp head 14 and the joint 15.
