A sliding channel is provided on the check seat 10 and the sealing gasket 12. The sliding rod 14 is passed through the sliding channel and both ends pass through the sliding channel. One end of the sliding rod 14 is provided with a water flow seat 14 for water flow to pass through. The water flow seat 14 is located in the second channel 18. A spring is provided between the water flow seat 14 and the sealing gasket 12. A sealing block 16 is provided at the other end of the sliding rod 14. The sealing block 16 resists the check plate 11 to close the sliding channel. A push rod 20 is provided, and a push plate 19 is provided at one end of the push rod 20. The control seat 1 is matched with the shape of the push rod 20 to open a push channel. The push rod 20 is passed through the push channel and passes through the control seat 1 to resist the water seat 14. The swing rod 4 is provided with a resisting block 22 for resisting the push rod 20. The resisting block 22 is provided on the swing rod 4. When the swing rod 4 swings, the resisting block 22 resists the push rod 20 to push the push rod 20 to slide into the second channel 18. A return channel is opened on the control seat 1, and a return block 21 is provided on the push rod 20. A first return spring is sleeved on the push rod 20, and one end of the first return spring resists the return block 21, and the other end of the first return spring resists the inner wall of the return channel. A second return spring 23 is provided between the resisting block 22 and the control seat 1.

[0025] In order to prevent impurities in the water flow from clogging the sliding channel, a connecting block 15 is provided on the check plate 11 , and the sliding rod 14 passes through the connecting block 15 . A filter sleeve 17 for filtering impurities is sleeved on the connecting block 15 .

[0026] In order to match the buoyancy of fluids in different boxes and make it more universal, the buoyancy block 8 is a buoyancy bottle that can be filled with water, and the buoyancy bottle is sleeved on the pull rope 5.

[0027] In order to allow the pull rope 5 to pass through the adjustment disk 7 better, the adjustment disk 7 is further provided with an escape opening for the pull rope 5 to pass through.

[0028] In order to facilitate installation and replacement, the control seat 1 includes a first control seat and a second control seat, the first channel 9 is located on the first control seat, the second channel 18 is located on the second control seat, the first control seat and the second control seat are connected by bolts, and the sealing gasket 12 is located between the first control seat and the second control seat.

[0029] Working principle:

[0030] Connect the water inlet pipe 2 with the external water pipe, and then sink the counterweight 6 into the water tank. When there is no water in the water tank, the buoyancy sinks to the bottom. At this time, the swing rod 4 is forced to swing downward to compress the second return spring 23. At this time, the top block 22 resists the push rod 20, pushing one end of the push rod 20 to slide out of the push channel and push the water seat 14. The water seat 14 pushes the sliding rod 14 to slide, so that the sliding channel is connected to the second channel 18, and the second channel 18 is connected to the outside. At this time, under the action of water pressure, the check plate 11 is pushed to slide, and the sliding of the check plate 11 drives the sealing gasket 12 to deform, opening the check seat 10, and the water flow Water enters the first channel 9 from the water inlet pipe 2 and then flows out of the water outlet pipe 3 to add water to the water tank. The water in the water tank causes the buoyancy block 8 to float upward. When the buoyancy block 8 hits the adjustment disk 7, the tension of the pull rope 5 disappears, and then the second return spring 23 returns to its position, releasing the resistance between the push block 22 and the push rod 20, allowing the push rod 20 to return to its position. The push rod 20 returns to its position, sealing the push channel. The spring then resets, causing the water overflow seat 14 and the check plate 11 to return to their positions. The return of the water overflow seat 14 drives the sliding rod 14 to return to its position. The return of the sliding rod 14 drives the sealing block 16 to return to its position. The return of the check plate 11 seals the check seat 10, thereby stopping the water addition. When the water level needs to be adjusted, the adjustment disk 7 is directly adjusted so that the adjustment disk 7 is at different positions of the pull rope 5 to adjust the water level. When facing different buoyancy, water can be injected into the buoyancy block 8 to match different fluid densities.
