Abstract
The utility model discloses a water-leakage-preventing structure for a water inlet valve. The water inlet valve comprises a valve body, a water-stopping cup, a large floating bucket and a small floating bucket, wherein the water-stopping cup is connected to the valve body, the large floating bucket is movably connected to the water-stopping cup, and the small floating bucket is movably connected to the water-stopping cup or a component fixed relative to the water-stopping cup. The water-leakage-preventing structure is characterized in that one of the small floating bucket and the large floating bucket is provided with a roller, and the other of the small floating bucket and the large floating bucket is provided with a matching surface which can be separated from the roller to enable the large floating bucket to fall in the normal drainage process and can be matched with the roller in an abutting mode to enable he large floating bucket not to fall in the water leakage process. The water-leakage-preventing structure has the advantages that by adopting matching of the roller and the matching surface, the friction force is small, even if much dust accumulates on the matching surface, the roller can roll on the matching surface to drive the small floating bucket to rotate, and therefore the phenomenon that the normal use of the water inlet valve is influenced due to the fact that the small floating bucket can not rotate and leave is avoided.

When normal draining, water level declines rapidly, and the water velocity of discharge that counterweight chamber is 41 li is slower, now little keg float 40 under the effect of moment of torsion, rotate and the top of little keg float 40 to moving away from large keg float 30 directions, fitting face 60 leaves roller bearing 50, and large keg float 30 declines, and water intaking valve starts water inlet.
When in draining valve or water-closet tank, miscellaneous part causes toilet to leak extremely, water-closet tank water level declines slowly, water in counterweight chamber 41 flows out and makes there is no water in counterweight chamber 41 from spilled water hole 43, its moment of torsion cannot drive little keg float 40 to rotate, fitting face 60 is contact side under roller bearing 50 all the time, and large keg float 30 cannot drop and water intaking valve cannot be intake, and completes the preventing water leakage function of water intaking valve, can avoid the waste of water resource, cost-saving.
Owing to adopting coordinating of roller bearing and fitting face, frictional force is less, even if fitting face is piled up more dust, roller bearing still can roll to drive little keg float rotating opening on fitting face, avoids little keg float to arrange and affects the normal use of water intaking valve.
Please refer to Fig. 9 to Figure 11, another preferred embodiment of a kind of water intaking valve water leak preventing structure.
The difference of the present embodiment and a upper embodiment is, described roller bearing 50 rotates and is installed in little keg float 40, and described large keg float 30 is provided with a catch 33 extending towards little keg float 40 directions, and the bottom surface of this catch 33 is described fitting face 60.
In the present embodiment, described catch 33 is positioned at the junction of adjusting screw(rod) 70 and large keg float 30.
In the present embodiment, described little keg float 40 is convexly equipped with spaced apart two protruding pin 47, protruding pin 47 offers a Triaxial hole 48, and two ends of described roller bearing 50 are equipped with one second boss, and 2 second boss stretch into respectively two Triaxial holes 48 and rotate and coordinate with two Triaxial holes 48 respectively.
The preventing water leakage principle of this embodiment is identical with a upper embodiment.
The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
