Referring to fig. 3 and 15, when in use, one end of the floating ball valve, which is provided with the first liquid inlet 101, is inserted into the water inlet at the bottom of the water tank, then water from an external water source enters the valve body 100 from the first liquid inlet 101, then flows to the first liquid outlet 102 through the first valve core 200, flows to the second liquid outlet 131 of the outer sleeve, and then flows out from the second liquid outlet 131 of the outer sleeve, namely flows into the water tank; when the water level in the water tank rises, the first floating ball 300 can be driven to rise, at this time, the first floating ball 300 can rise to drive the driving frame 110 to rise along the axial direction of the valve body 100 through the lever 210, the second magnet 111 in the driving frame 110 can drive the first magnet 201 in the first valve core 200 to rise, when the water level in the water tank reaches a specified height, the first valve core 200 can be abutted with the first convex ring 132, so that the second liquid outlet 131 on the outer sleeve is sealed, water in the valve body 100 cannot flow into the water tank through the second liquid outlet 131, water in the water tank is prevented from overflowing, and the safety and stability of water inflow in the water tank are ensured.
Specifically, the floating ball valve is clamped with the water tank, and the joint is sealed through the sealing ring, so that water leakage is avoided.
In the prior art, the control of the water tank is determined by the electromagnetic valve and the mechanical floating ball, when the water level in the water tank reaches a certain height, the mechanical floating ball triggers the electromagnetic valve, and then the electromagnetic valve closes the water inlet channel, but when the water flow is turbulent, the excited water flow easily causes the mechanical floating ball to mistakenly shock the electromagnetic valve, so that the electromagnetic valve is closed when the water level of the water tank is lower; moreover, the mechanical floating ball increases along with the use time, and faults are easy to occur, so that the floating ball can not trigger the electromagnetic valve, and water in the water tank overflows.
Referring to fig. 3, in the floating ball valve provided in this embodiment, the first floating ball 300 (the buoyancy of the water to the first floating ball 300 and the height of the water to raise the first floating ball 300) drives the driving frame 110 to move upwards by the lever principle, so as to drive the first valve core 200 to raise; when the water level reaches the designated position, the first valve core 200 can be abutted against the first convex ring 132 on the outer sleeve under the drive of the first floating ball 300, so that the second liquid outlet 131 is sealed. The lever 210 principle is used for controlling the opening and closing of the second liquid outlet 131, even if the flow velocity of water is overlarge, the first floating ball 300 is impacted to the maximum height, so that the first valve core 200 seals the second liquid outlet 131, after the water flow in the water tank is stable, the height of the first floating ball 300 is lowered, the first valve core 200 is lowered along with the lowering, and the second liquid outlet 131 is unblocked.
Referring to fig. 5 and 6, when the first floating ball 300 moves upward, the driving frame 110 can be moved upward by the lever 210. When there is no water in the water tank, the bottom of the first floating ball 300 contacts with the bottom of the water tank, and at this time, the first liquid outlet 102 and the second liquid outlet 131 are both smooth, so that the water of the external water source can enter the valve body 100 through the first liquid inlet 101, then is discharged into the housing through the first liquid outlet 102, and then is discharged into the tank 800 through the second liquid outlet 131.

When the first floating ball 300 rises along the axial direction of the valve body 100 under the action of water flow, the lever 210 can rotate with the joint of the first protrusion 211 and the groove 121 as a rotation axis, so that the second protrusion 212 can rise along with the lever 210, and further drive the driving frame 110 connected with the second protrusion 212 to rise, and meanwhile, the driving frame 110 drives the first valve core 200 to move upwards. When the water level in the tank 800 reaches the designated height, the first valve core 200 is abutted against the first convex ring 132 due to the rise of the height of the first floating ball 300, so that water cannot flow into the tank 800 from the valve body 100, and water overflow from the tank 800 due to the excessive water level is avoided.
The size of the connecting seat 112 on the driving frame 110 along the radial direction of the valve body 100 is larger than the size of the second protruding block 212 along the radial direction of the valve body 100, so that the second protruding block 212 can drive the connecting seat 112 to move upwards along the axis of the valve body 100 when the lever 210 rotates.

And the portion of the water seal tube 500 located outside the valve body 100 is sealingly connected to the end cap 130 so that water within the valve body 100 cannot flow out of the annulus between the end cap 130 and the water seal tube 500. By this arrangement, the water flow in the valve body 100 can flow into the water shutoff pipe 500 only and then be discharged from the second drain port 131 formed in the cap 130.
And, be provided with second case 600 in the water sealing pipe 500 to the top of second case 600 passes second leakage fluid dram 131 and is connected with second floater 400, and second floater 400 cover fixed setting is at second case 600 top, and exists annular space between second floater 400 and the end cover 130, guarantees that rivers can flow to the box 800 through second leakage fluid dram 131. When the water flow in the box 800 rises, the water flow can continuously flow into the water sealing pipe 500 when the first valve core 200 driven by the first floating ball 300 cannot seal the water sealing pipe 500, so that the water flows into the box 800 through the second liquid outlet 131, the second floating ball 400 can rise under the influence of the water level, then the second floating ball 400 can drive the second valve core 600 in the water sealing pipe 500 to rise, and when the water level reaches a designated height, the second valve core 600 can be abutted with the first convex ring 132 in the end cover 130 (outer cover) under the drive of the second floating ball 400, so that the second liquid outlet 131 is sealed.
It should be noted that, when the water sealing pipe 500 is disposed in the valve body 100, the first valve core 200 abuts against the second convex ring 520 at the bottom of the water sealing pipe 500, so as to seal the water sealing pipe 500, so that the water flow in the valve body 100 cannot enter the water sealing pipe 500.
Wherein, the annular space between the second valve core 600 and the second drain port 131 is used for water to flow out from the second drain port 131.
In an alternative of this embodiment, the first valve core 200 and the second valve core 600 are each provided with a gasket 700. When the water sealing pipe 500 is not arranged in the valve body 100, the first valve core 200 better completes the sealing operation of the valve body 100 together with the first convex ring 132 through the sealing gasket 700. When the water sealing pipe 500 is arranged in the valve body 100, the first valve core 200 and the second convex ring 520 better together complete the sealing operation of the water sealing pipe 500 through the sealing gasket 700, and the second valve core 600 completes the sealing operation of the second liquid outlet 131 through the sealing gasket 700.
13-15, an embodiment of the present invention provides a water tank including a tank body 800 and a float valve; the float valve is located inside the case 800.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
