The floating ball 3 is fixedly connected with a connecting rod 13, one end of the connecting rod 13 penetrates through the first center frame 2 and is magnetically connected with the valve core 5, and corresponding magnets 14 are arranged on one end of the connecting rod 13 and the valve core 5;
The floating ball 3 can drive the valve core 5 to move upwards through the connecting rod 13, and the disconnection or the communication between the second cavity 12 and the first cavity 11 is realized through the up-and-down movement of the valve core 5; and the valve core 5 is supported by the limiting mechanism 15 and is limited to move downwards by the limiting mechanism 15. Namely, after the valve core 5 moves upwards, the second cavity 12 and the first cavity 11 cannot be communicated through the valve core 5, the second cavity 12 and the first cavity 11 are in a disconnected state, and after the valve core 5 moves downwards, the second cavity 12 and the first cavity 11 are communicated through the valve core 5, and the second cavity 12 and the first cavity are in a communicated state.
The valve core 5 is provided with a first channel 16, the second cavity 12 is communicated with the first cavity 11 through the first channel 16, and the first channel 16 is provided with a normally closed reset valve 17 for controlling on-off.
In the valve,: the first cavity 11 and the second cavity 12 can be communicated through the valve core 5 or through the first channel 16.
When in installation, the lower end of the valve body 1 is communicated with a water inlet (connected with a tap water valve), and the upper end of the valve body 1 is communicated with a water outlet (connected with a tap water valve); namely, the valve needs to be vertically arranged on the tap water gate valve.
As shown in fig. 5, the present valve includes the following states during operation:

Meanwhile, as the water pipe valve is in a closed state, no water flows out.
State 2, when the tap water valve is opened, water flows into the upper cavity through the valve core 5, and the floating ball 3 floats (moves) together with the valve core 5; when the valve core 5 moves upwards, the second cavity 12 and the first cavity 11 cannot be communicated through the valve core 5, so that water flow does not flow into the upper cavity any more.
The state 3, control the normally closed reset valve 17, make the first channel 16 in the state of link up, communicate through the first channel 16 between first cavity 11 and the second cavity 12; the water flow can pass through the second cavity 12, the first channel 16 and the first cavity 11 in sequence and enter the upper cavity 6.
After the water is continuously injected into the upper cavity, the floating ball 3 moves upwards under the action of buoyancy force, and when the buoyancy force is greater than the suction force between the magnets 14, the two magnets 14 are finally separated, and the floating ball 3 is propped against the lower plane of the second center frame 9 (floating stops). At this time, the valve core 5 is not subjected to the suction force of the magnet 14 below the floating ball 3; and then the tap water valve is closed, the pressure between the upper cavity 6 and the lower cavity 7 is in a balanced state, the valve core 5 descends to the limiting mechanism 15 by self weight, the normally closed reset valve 17 resets, the first channel 16 is in a disconnected state, and the second cavity 12 is not communicated with the first cavity 11 through the first channel 16.
The tap water valve is opened again, the second cavity 12 is communicated with the first cavity 11 through the valve core 5, namely, water flows sequentially through the second cavity 12, the valve core 5 and the first cavity 11 and enters the upper cavity 6, and finally flows out through the tap, so that tap water can be normally used.
And 4, closing the water tap after water consumption is finished, wherein the floating ball 3 is kept in a floating state by the water in the upper cavity, and the valve core 5 is always kept at a sinking position. The water tap can be normally used by directly opening and closing again, and even if water is stopped at the moment because the valve is in a closed state, the upper cavity 6 can keep water, and the water tap can be normally used when water is supplied again.
In state 5, if the valve (tap water valve or water tap) is forgotten to be closed when water is stopped, the water in the upper cavity 6 flows back, the floating ball 3 descends to the bottom dead center (on the upper plane of the first center frame 2) under the condition of no buoyancy, and is adsorbed to the magnet 14 of the valve core 5 to return to state 1.
Further, the limiting mechanism 15 is a bottom bracket, and the bottom bracket is fixed in the second cavity 12, and supports the valve core 5 through the bottom bracket and limits the valve core 5 to move downwards; the shoe is provided with a third through hole 18, so that water flow can flow into the second cavity 12 through the third through hole 18.

The valve core 5 is provided with a communication hole 21, and the bottom of the valve core 5 is provided with a convex edge 22; when the valve core 5 moves upwards to enable the flange 22 to be attached to the bottom of the valve frame 4, the second cavity 12 cannot be communicated with the first cavity 11 through the valve core 5, and when the flange 22 is not attached to the bottom of the valve frame 4, the second cavity 12 is communicated with the first cavity 11 through the communication hole 21 on the valve core 5.
Further, in order to improve the sealing effect, a rubber pad 23 is sleeved on the valve core 5, the rubber pad 23 is located above the convex edge 22, namely, after the valve core 5 moves upwards, the rubber pad 23 is located between the convex edge 22 and the bottom of the valve frame 4.
Further, the novel center rest further comprises a second spacer 24, the second spacer 24 is arranged between the first center rest 2 and the second center rest 9, a certain distance between the first center rest 2 and the second center rest 9 can be ensured through the second spacer 24, and the novel center rest is convenient to install.
Further, the normally-closed reset valve 17 is preferably configured to be normally closed as long as the on/off of the first passage 16 can be controlled by a structure common in the art such as a shut-off valve.

As shown in fig. 2, taking pressing as an example, the valve rod 25 is pressed (the return spring 26 is compressed) so that the end of one end of the valve rod 25 is moved away from the first passage 16, thereby bringing the first passage 16 into a communicating state; after the pressing is released, the return spring 26 releases elastic potential energy to reset the return valve, and the normally closed state is restored, namely, the first channel 16 is blocked. As shown in fig. 4, the same applies to the pulling, except that: by pulling the valve stem 25 (the return spring 26 is compressed), the end of one end of the valve stem 25 is moved away from the first passage 16, thereby bringing the first passage 16 into communication.
Further, in order to secure the smoothness of the movement of the connecting rod 13, the other end of the connecting rod 13 thereof may protrude through the second center frame 9.
