Technical Field

The invention relates to automatic water replenishing equipment for a water tank, in particular to a universal automatic water replenishing ball valve which can be normally used under various water pressure conditions, and belongs to the field of automatic water replenishing equipment.

Background

In daily production life of people, various automatic water replenishing devices can not be left everywhere in cities or rural areas, in factories, hospitals, kitchens and restaurants, for example, containers such as various water storage tanks, toilet water tanks and the like which are common in daily life of people can not be left. From the appearance, these automatic water supply equipment can be said to be various, and the diverse, but can mainly be divided into two main categories from the functional structure, promptly: a piston type hydraulic water level control valve and a lever type automatic water-replenishing ball valve.

The piston type hydraulic water level control valve mainly comprises a valve body, a piston, a floating ball, a lever and the like, and the working principle is that when the water level in a water pool or a water tank drops to exceed a preset value and goes off-line, the floating ball in a floating cavity falls to drive the lever to open a pilot hole of the control valve, an air hole leading to an upper cavity of the piston is opened under the action of water pressure in a pipeline, the pressure of the upper cavity of the piston is reduced, a pressure difference is formed between the upper part and the lower part of the piston, and the piston is opened under; when the water level rises to a preset value and reaches the upper line, the floating ball rises to drive the lever to close the pilot hole of the control valve, the pressure of the upper cavity of the piston is continuously increased, and when the pressure of the upper cavity of the piston is greater than the pressure of water supplied by the water pipe, the piston is closed to stop water supplement, so that the automatic water supplement function is realized in a reciprocating manner. Therefore, although the piston type hydraulic water level control valve has the advantages of small volume, large water yield, high water replenishing speed and the like, the piston is opened by hydraulic pressure to supply water according to the working principle, so that the application range of the piston type hydraulic water level control valve can be limited to be used only under the condition of large water pressure in a water supply pipeline, and otherwise, normal automatic water replenishing cannot be realized. Moreover, when the water replenishing is about to be completed, namely the water level in the water tank is close to the water level stop line, the internal and external thrust acting on the piston is in a game state, and the automatic water replenishing complete stop can be really realized in a long time.

The lever-type automatic water-replenishing ball valve mainly consists of valve body, floating ball, connecting rod, crank arm and piston. The working principle is simple, namely a floating ball moves up and down along with the water level to drive a connecting rod and a crank arm to push and pull a piston in a valve body, so that the piston of the automatic water replenishing ball valve is opened and closed. When the water level of the water tank drops, the floating ball drives the connecting rod and the crank arm to pull the piston in the valve body outwards to open the water outlet of the water replenishing ball valve for water replenishing; when the water level rises, the floating ball drives the connecting rod and the crank arm to push and press the piston in the valve body inwards until the water replenishing of the water outlet of the water replenishing ball valve is completely closed and the water replenishing is stopped. The lever type automatic water replenishing ball valve has the advantages of simple structure, low production cost and the like, but the working principle of the lever type automatic water replenishing ball valve is that a piston is pushed and pulled by utilizing a lever to achieve the purpose of opening and closing the water replenishing ball valve, so that the lever type automatic water replenishing ball valve is more suitable for being used on a pipeline with lower water pressure in a water supply pipe, and otherwise, the problems of untight closing, failure of automatic water replenishing and the like can occur. In addition, similar to the piston type hydraulic water level control valve, when the water level in the water tank is close to the water level stop line, the lever type automatic water replenishing ball valve is in a game state by the internal and external thrust acting on the piston, and the automatic water replenishing can be stopped completely in a real way only in a long time.

In summary, although the piston type hydraulic water level control valve and the lever type automatic water replenishing ball valve are two types of automatic water replenishing equipment which are most widely used at present, due to the functional structure defects of the piston type hydraulic water level control valve and the lever type automatic water replenishing ball valve, the requirements of people for normal use under different pressure water supply pipelines are difficult to meet, and particularly, when an automatic water replenishing container is produced, a manufacturer is difficult to select automatic water replenishing equipment which is suitable for normal use under various water pressure conditions, such as a common toilet water tank, and the manufacturer is difficult to find the automatic water replenishing equipment which is suitable for normal use on various water supply pipelines with different water pressures; therefore, the invention provides the universal automatic water replenishing equipment which is reasonable in structure, simple to install, convenient to use, fast and efficient, and solves the problem at present.

The application scene of the universal automatic water replenishing ball valve and the toilet water tank in the embodiment illustrates the use state.

When the universal automatic water replenishing ball valve is used, an outer water inlet 1-1 of the universal automatic water replenishing ball valve in the embodiment is communicated with a water supply pipeline, the direction of an outer water outlet 1-2 is ensured to be vertical downwards, then a water path switch is opened, at the moment, the static valve core 4, the static valve core water inlet 4-1 and the movable valve core water outlet 5-1 of the movable valve core 5 of the universal automatic water replenishing ball valve in the embodiment are communicated to enable the valve body assembly 100 to be in a completely opened state, as shown in figures 4 and 5, water in the water supply pipeline starts to be injected into a water tank after sequentially passing through the outer water inlet 1-1, the static valve core water inlet 4-1, the movable valve core water outlet 5-1 and the outer water outlet 1-2, when the water level rises to be close to the bottom of the outer float 10, the bottom water float switch 10-2 hung in the water inlet 10-1 floats until the water inlet 10-1 at the bottom of the outer, then, the outer float 10 begins to float upwards along with the rising of the water level in the water tank, at the moment, the inner float 13 is in a sinking state relative to the outer float 10, and further prizes one end of the inner float transverse lever 15 close to the hook fixing block 8-3 to move upwards in the inner float connecting lever limiting slide way 17 along the vertical direction, meanwhile, as the hook slide way 18-1 is designed in an arc shape, when the inner float transverse lever 15 prizes upwards in the inner float connecting lever limiting slide way 17, the hook 18 moves towards the hook fixing block 8-3 relatively under the action of the arc-shaped hook slide way 18-1, as shown in figure 7, namely, when the inner float transverse lever 15 moves upwards in the inner float connecting lever limiting slide way 17 along the vertical direction, the hook 18 is pushed inwards through the arc-shaped hook slide way 18-1 until the outer float 10 rises to be close to the water level of the water tank, the hook 18 hooks the lower part of the hook fixing block 8-, at the moment, the outer float 10 does not rise under the action of the hook 18, the water level in the water tank is thrown to continue rising, when the water level in the water tank is concealed from the upper edge of the outer float 10, the outer float inner cavity 10-3 starts to feed water, the inner float 13 floats upwards and drives one end of the inner float horizontal lever 15 close to the hook fixed block 8-3 to start to push and press downwards, the lower end of the hook 18 is pulled outwards under the combined action of the inner float connecting lever limiting slide way 17 and the hook slide way 18-1 until the hook 18 is completely separated from the hook fixed block 8-3, as shown in figures 3, 6, 7 and 8, due to the buoyancy effect of the limitation of the hook 18 on the outer float 10, the outer float 10 quickly floats upwards to drive the outer float connecting rod 11 to drive the movable valve core 5 to rotate through the semicircular gear 9 and the valve core gear 7 to completely close the waterway of the movable valve core water outlet 5-1 and the, the water replenishing stops immediately, the long critical point state of the existing piston type hydraulic water level control valve and lever type automatic water replenishing ball valve when the water replenishing is about to be completed is overcome, the automatic water replenishing is rapidly and immediately stopped completely, and the game state when the water replenishing is about to be completed is solved.

When water is discharged, the water level of the water tank is lowered, the outer float 10 falls along with the water level, at the moment, the bottom water float switch 10-2 is still in a floating state, the water level in the outer float inner cavity 10-3 is unchanged, the state of the inner float 13 is also unchanged, and the hook 18 is kept in a closed state, moreover, when the universal automatic water replenishing ball valve in the embodiment is assembled, the position relation between the outer float connecting rod 11, the inner float transverse lever 15 integrated with the outer float connecting rod 11, the hook 18 and the hook fixing block 8-3 is required to be adjusted, so that when the outer float 10 drives the three of the outer float connecting rod 11 to fall below the hook fixing block 8-3 integrally along with the water level, namely, the hook 18 cannot touch the hook fixing block 8-3 even if opened;

and, with the continuous decline of the water level in the cistern, when the cistern water level drops to leave the water float switch 10-2 of bottom, the water float switch 10-2 of bottom of outer float falls, the bottom water inlet 10-1 of outer float opens, the water in the lumen 10-3 of outer float flows out, and the water level in lumen 10-3 of outer float begins to drop, inner float 13 begins to sink too and drive the end close to fixed block 8-3 of the couple of inner float lever 15 to tilt up, push and press the couple 18 inwards under the coaction of connecting lever spacing slideway 17 of inner float and couple slideway 18-1 of inner float until couple 18 is opened completely, because the connecting rod 11 of outer float and inner float lever 15, couple 18 integrated with it are located under fixed block 8-3 of the couple at this moment, even couple 18 is opened completely will not catch fixed block 8-3 of the couple, moreover, the water in the outer floating inner cavity 10-3 is completely discharged at the moment.

Simultaneously with the water discharging process, the outer floating connecting rod 11 is driven to drive the movable valve core 5 to rotate through the semicircular gear 9 and the valve core gear 7 in the falling process of the outer floating 10 so as to communicate the water outlet 5-1 of the movable valve core with the water inlet 4-1 of the static valve core, when the outer floating 10 sinks to the bottom dead center, as shown in figures 4 and 5, the water outlet 5-1 of the movable valve core is completely communicated with the water inlet 4-1 of the static valve core, and the water can be rapidly supplemented into the water tank.

The automatic water replenishing function of the universal automatic water replenishing ball valve can be realized by reciprocating.

The universal automatic water replenishing ball valve has the outstanding substantial characteristics through the design of the components such as the outer float 10, the inner float 13, the inner float transverse lever 15, the hook 18 and the like, firstly, the relative upward movement of the inner float 13 and the inner float transverse lever 15 limits the buoyancy advance of the outer float 10 through the hook 18, then, the downward relative movement of the inner float 13 and the inner float transverse lever 15 unhooks the hook 18 to release the buoyancy advance pressed by the outer float 10, further, the outer float 10 is driven to rapidly ascend to completely close the passage between the water outlet 5-1 of the movable valve core and the water inlet 4-1 of the static valve core, and the game state of the piston type hydraulic water level control valve and the lever type automatic water replenishing ball valve in the prior art when water replenishing is about to be completed does not exist.

The universal automatic water replenishing ball valve is a universal automatic water replenishing device which is reasonable in structure, simple to install, convenient to use, rapid and efficient and suitable for being normally used under various water pressure conditions.
