[0026] The limiting mechanism 6 includes a limiting rod 601, a limiting column 602, a valve core 603 and a valve plug 604.

[0031] In this embodiment, by making the surface of the rotating shaft 19 fixedly connected to the inside of the sealing block 8, the bolt 3 can drive the sealing block 8 to move through the rotating shaft 19, thereby achieving the effect of driving the sealing block 8 to move.

[0033] In this embodiment, by fixing the bottom of the first spring 7 to the top of the valve plug 604 , the first spring 7 can limit the valve plug 604 , thereby achieving the effect of limiting the valve plug 604 .

[0034] As a technical optimization solution of the utility model, a one-way bearing 20 is fixedly connected to the top of the surface of the bolt 3, and a handle 2 is rotatably connected to the surface of the one-way bearing 20.

[0036] As a technical optimization solution of the utility model, the top of the limiting rod 601 passes through the bolt 3 and extends to the top of the bolt 3. The top of the limiting rod 601 is fixedly connected to the rotating block 4, and two limiting grooves 9 are provided on the surface of the rotating block 4.

[0037] In this embodiment, by fixing the bottom of the rotating block 4 with the top of the limiting rod 601 , the limiting rod 601 can fix and support the rotating block 4 , thereby achieving the effect of fixing the rotating block 4 .

[0038] As a technical optimization solution of the utility model, a limiting frame 10 is provided on the top of the handle 2, and two limiting blocks 16 are fixedly connected to the surface of the inner wall of the limiting frame 10. The limiting blocks 16 extend from one side close to the limiting groove 9 to the inside of the limiting groove 9 and contact the inside of the limiting groove 9.

[0039] In this embodiment, by making the surface of the limiting block 16 contact with the inside of the limiting groove 9, the handle 2 can drive the rotating block 4 to rotate through the limiting frame 10, thereby achieving the effect of driving the rotating block 4 to rotate.

[0040] As a technical optimization solution of the present utility model, a second spring 15 is arranged inside the oil outlet 13 , and a pressure plug 14 is fixedly connected to the left side of the second spring 15 .

[0042] Working principle: First, the sealing sleeve 5 is used to seal the inside of the oil inlet 12, the inside of the oil outlet 13 and the inside of the overflow port 11 respectively, so as to maintain the pressure inside the device body 1, so that the solution passes through the oil inlet 12 and pushes the pressure plug 14 to compress the second spring 15, and can be moved out through the oil outlet 13. When the internal pressure of the device body 1 reaches a certain level, the handle 2 is turned to drive the bolt 3 to move through the one-way bearing 20, so that the bolt 3 drives the sealing block 8 to move, and the sealing block 8 drives the valve plug 604 to move upward through the first spring 7. When the first spring 7 is damaged, the limit block 16 is moved inside the handle 2, thereby driving the limit block 16 to move to the inside of the limit groove 9, so as to facilitate the rotation of the rotating block 4, that is, the rotating block 4 drives the connecting sleeve 17 to rotate through the limit rod 601. The valve plug 604 moves upward through the valve core 603, thereby canceling the seal of the overflow port 11, and the limiting rod 601 moves inside the limiting column 602 through the bolt 3, thereby canceling the seal of the overflow port 11, thereby achieving the effect of facilitating the auxiliary excess solution to flow out through the overflow port 11, and solving the problem that most of the existing condensation dripping high-position reaction tank gradient overflow devices control the liquid level of the internal solution of the condensation dripping high-position reaction tank through the pilot valve core 603. The pressure spring of the pilot valve core 603 is easily damaged by the internal solution of the condensation dripping high-position reaction tank after long-term use, making the pressure spring difficult to expand and contract, making it difficult to push the pilot plunger when the pressure in the cavity reaches the critical point, and when the pressure in the cavity becomes smaller, it is difficult for the pilot plunger to seal the overflow port 11, thereby expanding the overflow problem.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
