Move, the drain valve starts to drain water. At this time, because the half-row floating bucket assembly 42 is not suppressed and is in a floating state under the buoyancy of the water, when the valve core 23 moves up to the predetermined position, the half-row barb 25 and the half-row hook 424 hooked together, the drain valve continues to drain water, and the water level continues to drop until the half row of floating barrels 421 loses buoyancy and falls downwards, and drives the half row of racks 422 to also fall downwards, and then the half row of swing rods 423 rotates to make the half row of hooks 424 Separated from the half row of barbs 25, the starting assembly 2 falls downwards under the action of gravity so that the valve core 23 seals the drain port and completes half draining. While the above process is going on, since the full row of buttons 31 is not pressed, the limiter 6 is still in the limit position, limiting the floating stroke of the full row of buoyant bucket assemblies 32, so that the full row of buoyant bucket assemblies 32 keep the initial position unchanged.

As shown in Figure 8 and Figure 9, when fully draining, press the full row of buttons 31, so that the first swing arm 62 of the limiter 6 is pressed down, driving the limiter 6 to rotate, and then the second swing arm 63 is changed from the original The limit position moves to the step-off position, so as to be away from the limit portion 321 on the upper end of the full-row rack 323 of the full-row floating bucket assembly 32, and give way to the floating stroke of the full-row floating bucket assembly 32.

When the valve core 23 moves up to the predetermined position, the full row of barbs 24 Hooked with the hook 325 of the whole row, the drain valve continues to drain water, and the water level continues to drop until the floating barrel 322 of the whole row loses buoyancy and falls downward, and drives the rack 323 of the whole row to also fall downward, and then the swing rod 324 of the whole row rotates The whole row of hooks 325 is separated from the whole row of barbs 24, and the starting assembly 2 falls downward under the action of gravity so that the valve core 23 seals the drain port and completes the full drainage. The stopper 6 is under the action of the counterweight 64 Return to the limiting position from the evacuation position, so as to limit the floating stroke of the full row of buoyant bucket assemblies 32 again. During the above-mentioned full drainage process, the half row of floating bucket assemblies 42 will fall before the full row of floating bucket assemblies 32, and will not affect the full drainage.

Of course, a position-limiting part can also be set on the half-row floating bucket assembly 42 at the same time, and another half-row space-limiting part is set up, and this space-limiting part drives and connects the half-row button 41 and carries out position-limiting and summing to the half-row floating bucket assembly 42. Make way, so that the full-row control mechanism 3 and the half-row control mechanism 4 can better independently control the drainage, that is, when the water is not drained, the full-row floating bucket assembly 32 and the half-row floating bucket assembly 42 are both limited and do not float. When full row, press the full row button 31 to release the limit to the full row of floating bucket assembly 32, the full row of floating bucket assembly 32 plays a role in controlling the full drainage, and the half row of floating bucket assembly 42 is limited and does not work; During rowing, press the half-row button 41 to release the limit to the half-row floating bucket assembly 42, the half-row floating bucket assembly 42 plays a role in controlling the semi-drainage, and the full row of floating bucket 32 is limited and does not work.

In this embodiment, the limiting part can also be arranged on the full row of swing rods 324 or directly on the full row of floating barrels 322, as long as the limiting part 6 can be in the limiting position and can cooperate with the limiting part. To limit the position of the buoyant bucket assembly, it is only necessary that the position-limiting part can be separated from the position-limiting part to make way for the floating-barrel assembly when the position-limiting part is in the relief position, and the position of the position-limiting part can be selected according to needs.

For transmission cooperation, the valve body 1 is provided with a first protrusion 73 corresponding to the coupling block 71 . In the initial state, the actuating arm 21 and the driven arm 22 are connected through the coupling block 71, the piston 511 drives the actuating arm 21 and the driven arm 22 to rotate around the pin shaft 26 together, and the spool 23 is lifted by the driven arm 22 Realize drainage; the piston 511 stroke continues downward, and the driving actuator arm 21 and the driven arm 22 continue to rotate around the pin shaft 26 until the coupling block 71 contacts the first protrusion 73. At this time, the piston 511 stroke continues downward, so that the protrusion The block presses the coupling block 71 to make the coupling block 71 swing relative to the driven arm 22, and then the block 711 of the coupling block 71 is disengaged from the buckle groove 213, and enters the out-of-control state. At this time, the piston 511 and the starting assembly 2 They do not affect each other, the starting component 2 is kept lifted by the hooking effect of the floating bucket component, and the drain valve continues to drain water. After the drainage is completed, the starting component 2 can fall back freely, the piston 511 resets, and the coupling block 71 and the first protrusion 73 Disengaged, and then reset under the action of the tension spring 72 to make the block 711 snap into the buckle groove 213 of the coaxial part again.

At this time, the piston 511 and the starting assembly 2 do not affect each other, and the starting assembly 2 is suspended by the floating bucket assembly. The connecting function keeps the lifting state, and the drain valve continues to drain water. After the draining is completed, the floating bucket assembly falls, the starting assembly 2 falls back, and the actuating block 74 resets under the action of the compression spring 75. At this time, even if the water in the hydraulic cylinder has not been drained , the piston 511 has not been reset, and it does not affect the fall of the starting component 2, ensuring that the starting component 2 can seal the drain in time, and the drainage and water stop stability of the hydraulic drain valve are good.
