[0002] A check valve is installed in a pipeline. The fluid can only flow along the water inlet, and the medium at the water outlet cannot flow back, which is commonly known as a check valve. When there is pressure at the inlet, the valve plate is pressed to move, and the valve opens, and the liquid flows forward and out of the outlet. When the pressure at the outlet is higher than that at the inlet, the valve plate is pushed towards the inlet end to close the valve and prevent the liquid from flowing out of the inlet end.

[0028] To make the purpose, technical solution, and advantages of the present utility model clearer, the following will further describe in detail the implementation manners of the present utility model with reference to the attached drawings.

[0029] Please refer to Figures 1-5 As shown, this embodiment is a micro embedded one-way valve, including:

[0030] One-way valve part, the one-way valve part includes a housing 11, a cover plate 12, an active spring 13, a housing sealing ring 17, a valve plate 14, and a valve core 15. The bottom end inside the housing 11 is fixedly connected with the cover plate 12, and an active spring 13 is fixed on the inner wall of the upper end of the cover plate 12. The upper end of the active spring 13 is fixed to the lower edge of the valve plate 14, and the middle part of the lower end of the valve plate 14 is fixed with the valve core 15. The housing sealing ring 17 is embedded in the upper part of the outer surface of the housing 11;

[0031] The housing 11 provides an installation environment and meets the isolation and protection requirements for the internal structure. The cover plate 12 mounts the active spring 13. The telescopic property of the active spring 13 can meet the lifting requirements of the valve core 15. The valve plate 14 mounts and fixes the valve core 15. The opening and closing of the valve core 15 are used to control the fluid in the pipeline. The housing sealing ring 17, on the one hand, fixes the structure of the one-way valve, and on the other hand, ensures the connection sealing performance.

[0032] The outer edge of the lower end of the valve plate 14 is embedded with the valve plate sealing ring 16, and the valve plate sealing ring 16 extends into the annular groove opened at the outer edge of the upper end of the housing 11;

[0033] The valve plate sealing ring 16 seals the connection position of the valve plate 14.

[0034] A first opening 18 is formed through the middle of the housing 11, and a second opening 19 is formed through the middle of the cover plate 12, and the first opening 18 and the second opening 19 are in communication with each other;

[0035] The first opening 18 and the second opening 19 meet the requirements for the flow of fluid.

[0036] The lower end of the valve core 15 is enlarged in a conical shape, and the lower end of the valve core 15 abuts against the inner wall of the first opening 18;

[0037] By increasing the contact area, the valve core 15 can improve the sealing effect of the structure when the valve is closed.

[0038] A weight-reducing round opening is formed at the edge of the inner bottom end of the cover plate 12, and the shock-absorbing round opening is not provided through the cover plate 12;

[0039] The weight-reducing round opening is used to reduce the self-weight of the cover plate 12 to save costs.

[0040] Working principle: After connecting the one-way valve to the inner wall of the pipe orifice by using the housing sealing ring 17, when the water flow flows from the second opening 19 to the first opening 18, the impact force generated by the water flow acts on the valve plate 14 to drive the movable spring 13 to expand. At this time, the valve plate 14 disengages from the housing 11, and the water flow flows out through the first opening 18. After the water flow stops, the movable spring 13 resumes its deformation, causing the valve plate 14 to return to its original state. When the water flows through the first opening 18, the valve plate 14 isolates the water flow, and the movable spring 13 does not deform, so it is difficult to do so.

[0041] This step adopts a micro one-way valve, which has a simple structure, low use cost, is convenient for installation and use, and meets the use requirements.

[0042] Please refer to Figures 1-5 As shown in the figure, on the basis of the above-mentioned Embodiment 1, this embodiment further includes a limiting connection part. The limiting connection part includes an outer connection ring 21, an inner connection ring 22 and a limiting groove 23. The outer connection ring 21 is fixed to the inner wall of the pipe orifice, and the inner connection ring 22 is threaded on the inner side of the outer connection ring 21. Limiting grooves 23 are formed in the middle of the inner sides of the outer connection ring 21 and the inner connection ring 22, and the housing 11 sealing ring is in contact with the inner wall of the limiting groove 23;

[0043] The limiting grooves 23 on the inner sides of the outer connection ring 21 and the inner connection ring 22 cooperate to limit the structure of the housing 11 sealing ring.

[0044] The limiting connection part further includes an adjusting ring 24. There is a set of adjusting rings 24, two in a set, and the adjusting ring 24 is threadedly fixed on both sides of the outer connection ring 21 and the inner connection ring 22;

[0045] The adjusting ring 24 can satisfy the position adjustment and fixation between the outer connecting ring 21 and the inner connecting ring 22 to meet the requirements of different uses.

[0046] Threaded holes extending into the outer connecting ring 21 and the inner connecting ring 22 are formed through the inner and outer edges of the adjusting ring 24, and threaded posts 25 are provided with internal threads in the threaded holes;

[0047] The use of the threaded holes in cooperation with the threaded posts 25 structurally fixes the adjusted adjusting ring 24, thereby satisfying the structural fixation of the outer connecting ring 21 and the inner connecting ring 22 after adjustment.

[0048] Working principle: When the above-mentioned micro check valve is installed on the inner wall of the pipe orifice, if the outer connecting ring 21 meets the usage requirements, the housing sealing ring 17 can be directly embedded in the limiting groove 23. When the micro check valve is still relatively small, the inner connecting ring 22 can be added, and the adjusting ring 24 and the threaded posts 25 are used in cooperation for adjustment and installation, and then the housing sealing ring 17 is embedded in the limiting groove 23 on the inner side of the inner connecting ring 22.

[0049] This step can prevent the housing sealing ring 17 from detaching from the inner wall of the pipe orifice due to wear during long-term use, affecting the sealing performance, and can also adapt to different sealing connection requirements.

[0050] In the description of the present invention, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "install", "connect", and "couple" should be understood in a broad sense. For example, it 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
