[0020] The utility model provides a one-way valve structure for a water pump room, comprising an outer shell 1, a closing mechanism, a round block 2 and a fixed shell 3, the closing mechanism comprising a limit ring 4, four sliding rods 5, four sliding blocks 6, a baffle 7, a sealing ring 8, four springs 9 and an adjusting assembly, the adjusting assembly further comprising a round rod 10, a limit block 11, a threaded rod 12, a rotating ring 13, a connecting ring 14, two connecting rods 15 and a rotating member, the rotating member comprising a handle 16, a first gear 17 and a second gear 18. The above-mentioned solution solves the problem that the existing one-way valve pushes open the diaphragm by the pressure of the liquid when in use, but the distance between the diaphragm and the end cover cannot be adjusted, resulting in a fixed flow rate of the liquid and low practicality.

[0021] According to this specific embodiment, the limiting ring 4 is fixedly connected to the shell 1 and is located inside the shell 1. Four circular holes are evenly provided on the surface of the shell 1. The four sliding blocks 6 are slidably connected to the limiting ring 4 and are respectively provided inside the four circular holes. One end of the four sliding rods 5 is fixedly connected to the corresponding sliding blocks 6, and the other end of the four sliding rods 5 is fixedly connected to the baffle 7. The baffle 7 is provided on one side of the limiting ring 4. The sealing ring 8 is fixedly connected to the limiting ring 4 and is located on the outside of the baffle 7. The four The springs 9 are respectively wrapped around the surface of the corresponding sliding rods 5 and are located on one side of the corresponding sliding block 6. The adjusting component is arranged on one side of the baffle 7. When in use, the baffle 7 is loosened by the adjusting component. When the liquid flows in the forward direction, the liquid exerts pressure on the baffle 7, and the sliding block 6 slides accordingly. The spring 9 contracts, causing the baffle 7 to separate from the sealing ring 8. When water flows through and the liquid flows in the reverse direction, the liquid exerts pressure on the baffle 7, causing the baffle 7 to press against the surface of the limit ring 4 to close the limit ring 4.

[0022] Among them, one end of the round rod 10 is fixedly connected to the baffle 7, the other end of the round rod 10 is fixedly connected to the limit block 11 and is located on one side of the baffle 7, the threaded rod 12 is slidably connected to the limit block 11 and is covered on the outside of the limit block 11, the rotating ring 13 is threadedly connected to the threaded rod 12 and is covered on the outside of the threaded rod 12, the connecting ring 14 is rotatably connected to the rotating ring 13 and is located above the rotating ring 13, one end of the two connecting rods 15 is connected to the housing 1 The other ends of the two connecting rods 15 are fixedly connected to the connecting ring 14 and are located on both sides of the connecting ring 14. The rotating member is arranged below the rotating ring 13. When in use, the rotating ring 13 is driven to rotate by the rotating member. The limit block 11 is arranged in a square shape to limit the rotation of the threaded rod 12, so that the threaded rod 12 moves accordingly. The round rod 10 can slide inside the threaded rod 12, so that the baffle 7 moves accordingly, which is convenient for punching or closing, and the flow rate of the liquid can be adjusted at the same time.

[0023] Secondly, the handle 16 is rotatably connected to the housing 1 and passes through the housing 1. The first gear 17 is fixedly connected to the rotating ring 13 and is located below the rotating ring 13. The second gear 18 is fixedly connected to the handle 16 and is located at one end of the handle 16. The second gear 18 is engaged with the first gear 17. Rotating the handle 16 causes the second gear 18 to rotate accordingly. The second gear 18 drives the first gear 17 to rotate, and the rotating ring 13 adjusts the position of the threaded rod 12.

[0024] Then, one end of the snap ring 19 is fixedly connected to the rotating ring 13, and the other end of the snap ring 19 is rotatably connected to the connecting ring 14 and is located inside the connecting ring 14. The cross-section of the snap ring 19 is L-shaped. The snap ring 19 fixes the rotating ring 13 and the connecting ring 14 together, so that the position of the rotating ring 13 is fixed, thereby improving stability.

[0025] In addition, the fixed shell 3 is fixedly connected to the outer shell 1 and is located on the outside of the handle 16. The round block 2 is fixedly connected to the handle 16 and is located inside the fixed shell 3. When rotated properly, the round block 2 limits the position of the handle 16, so that the first gear 17 and the second gear 18 are always engaged, thereby improving practicality.

[0026] When using the present utility model, the handle 16 is rotated to rotate the second gear 18 accordingly, and the second gear 18 drives the first gear 17 to rotate, and the rotating ring 13 is rotated accordingly. The limit block 11 is arranged in a square, limiting the rotation of the threaded rod 12, so that the threaded rod 12 moves accordingly, and the round rod 10 can slide inside the threaded rod 12, so that the baffle 7 moves accordingly. When the liquid flows in the forward direction, the liquid exerts pressure on the baffle 7, the sliding block 6 slides accordingly, and the spring 9 contracts, so that the baffle 7 disengages from the sealing ring 8. When water flows through and the liquid flows in the reverse direction, the liquid exerts pressure on the baffle 7, so that the baffle 7 is pressed against the surface of the limit ring 4 accordingly, and the limit ring 4 is closed.

[0027] The above disclosure is merely one or more preferred embodiments of the present application and is not intended to limit the scope of the present application. A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
