The working principle of the double-liquid-level floating ball control liquid level valve structure is as follows:
1. the working process of the double-liquid-level floating ball control liquid level valve structure for controlling the high-liquid-level closing valve is as follows: when the water tank is replenished with water, the liquid level of the water tank can be slowly raised, the floating ball of the vertical rod at the end of the floating ball also can be slowly raised, when the floating ball is not contacted with the upper limit block, the whole lever system is in a balanced state, when the liquid level is raised to the position of the upper limit block, the floating ball is contacted with the upper limit block, and because the floating ball buoyancy pushes the vertical rod at the end of the floating ball upwards, the lever is out of balance and inclines rightwards, the lever swing can drive the interior of the floating ball pilot valve to be reversed through the connecting rod, so that the upper cavity interface and the lower cavity interface of the floating ball pilot valve are communicated, the drainage interface is in blocking, because the upper control cavity and the lower control cavity of the water inlet main valve are respectively communicated with the upper cavity interface and the lower cavity interface of the floating ball pilot valve through the connecting pipe and the floating ball pilot valve, at the moment, the water in the water inlet main valve can enter the upper control cavity and the lower control cavity of the water inlet main valve through the connecting pipe, and the valve generates valve closing pressure, so that the water inlet main valve is closed, the water tank stops replenishing water.
2. The working process that the double-liquid-level floating ball control liquid level valve structure controls the low-liquid-level valve to open is as follows: the water level of the water tank also slowly drops along with the water consumption of a user, the floating ball of the vertical rod at the end of the floating ball also slowly drops along with the water level of the water tank, the lever is still in a right inclined state at the moment, the lever also gradually restores to a balanced state along with the water level reduction, the lever does not immediately incline leftwards along with the reduction of the water level when restoring to the balanced state, when the water level drops to the position of the lower limiting block, the floating ball touches the lower limiting block, the vertical rod at the end of the floating ball is pulled by the gravity of the floating ball, the lever loses balance again and inclines leftwards, the swing of the lever drives the interior of the floating ball guide valve to change direction through the connecting rod, the upper cavity interface of the floating ball guide valve is communicated with the drainage interface, the lower cavity interface is blocked, at the moment, the water in the water inlet main valve enters the floating ball guide valve through the guide pipe and is in the blocked state, the water in the upper control cavity of the water inlet main valve enters the drainage interface of the guide pipe through the guide pipe, and discharging the water into the transparent external water tank, wherein the valve closing pressure of the water inlet main valve disappears at the moment, so that the water inlet main valve is opened, and the water tank starts to supplement water.
In the opening and closing process of the double-liquid-level floating ball control liquid level valve structure, the water level of the water tank can be directly observed through the transparent external water tank, and the operation is visual.
The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the utility model may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are within the protection scope of the technical solution of the present invention.
