The utility model provides a drain valve, which has the following working process:

In the initial state, i.e. when the water level in the tank reaches the working level, as shown in fig. 2. At this time, the limit slider 701 is located at the first position, and the top of the full-row rack 405 abuts against the limit slider 701, so that the full-row pontoon body 402 cannot float upwards; the half row pontoon rises to the highest position along with the water level, and the half row hook 504 is fastened to the half row barb 6012.

Pressing the half row key 501 drives the valve stem 601 up so that the water stop cover 602 opens the drain port 201, as shown in fig. 3-4. Specifically, the half-row hooks 504 are located below the half-row barbs 6012, and after the half-row keys 501 are released, the half-row hooks 504 are fastened to the half-row barbs 6012, so that the valve rod 601 drives the water stop cover 602 to open the water outlet 201. The water level of the water tank continuously drops until the half-row floating barrel loses buoyancy and falls downwards, the half-row rack 505 is driven to fall downwards, the half-row swing rod 503 rotates to enable the half-row hook 504 to be separated from the half-row barb 6012, and the valve rod 601 falls downwards under the action of gravity, so that the water stopping cover 602 closes the water outlet 201, and half-row water is completed.

The full row key 401 is pressed to drive the valve stem 601 to rise so that the water stop cover 602 opens the drain port 201, as shown in fig. 5 to 6. Specifically, the full row of keys 401 is pressed, so that the driving surface 4011 abuts against the guiding surface 7012, the limiting slider 701 slides from the first position to the second position, the full row of racks 405 is separated from the limiting slider 701, and thus the full row of pontoons are arranged in the through holes 7011 in a penetrating manner, so that the full row of pontoons move upwards, and the full row of racks 405 are driven to move upwards, so that the full row of hooks 404 are located under the full row of barbs 6011. When the full row of keys 401 is released, the full row of swing rods 403 rotate, so that the full row of hooks 404 are buckled on the full row of barbs 6011. The water level of the water tank continuously drops until the full-row floating barrel loses buoyancy and drops downwards, and drives the full-row rack 405 to drop downwards until the full-row rack 405 is separated from the through hole 7011, and the limit slider 701 is restored to the initial state under the action of the reset piece 702. Meanwhile, in the process that the full-row racks 405 drop downwards, the full-row swing rods 403 rotate to enable the full-row hooks 404 to be separated from the full-row barbs 6011, and the valve rods 601 drop downwards under the action of gravity, so that the water stopping cover 602 closes the water outlet 201, and full drainage is completed.

Simultaneously, the half row key 501 and the full row key 401 are pressed, and the valve stem 601 is driven to rise, so that the water stop cover 602 opens the drain port 201, as shown in fig. 7 to 9. When the full-row key 401 is pressed, the limit sliding block 701 and the full-row rack 405 lose the limit function, and the full-row pontoon floats freely; after the half row of keys 501 and the full row of keys 401 are released, the half row of hooks 504 and the full row of hooks 404 are respectively buckled with the half row of barbs 6012 and the full row of barbs 6011. The water level continuously drops, because half row's flotation pontoon height is higher than full row's flotation pontoon, half row's flotation pontoon subassembly loses buoyancy and descends preferentially, half row's couple 504 breaks away from with half row's barb 6012 mutually, full row's couple 404 still lock joint in full row's barb 6011 this moment for valve rod 601 still is in by the state of mentioning, the drain valve continuously drains, until the tank water level drops to make full row's flotation pontoon subassembly lose buoyancy, full row's flotation pontoon subassembly drops down and makes full row's couple 404 break away from full row's barb 6011, make valve rod 601 drop, make sealing up lid 602 close outlet 201, the drainage finishes, the drainage volume of this moment is the drainage volume of full row's water.

Therefore, the height of the water stopping part lifted by the full-row control device and the half-row control device is consistent, and the stable drainage is ensured; meanwhile, because the full-row control device and the half-row control device operate independently of each other, when the full-row key 401 and the half-row key 501 are pressed simultaneously, the full-row function of the drain valve is realized, and the question of the flushing performance of the drain valve by a user is eliminated.

The above embodiments are only for illustrating the technical concept and features of the present utility model, and are intended to enable those skilled in the art to understand the present utility model and implement it, and not to limit the scope of the present utility model. All equivalent changes or modifications made in accordance with the spirit of the present utility model should be construed to be included in the scope of the present utility model.
