Abstract
The utility model relates to an automatic pressure-adjusting water tank, which comprises a water tank body. The lower end of the water tank body is provided with a water inlet pipe and a drain pipe; the water inlet pipe and the drain pipe are provided with adjusting valves. The utility model, which is characterized in that the lower end of the water tank body is also provided with an air adjusting valve, has the advantages of simple structure and convenient use. Because air can be supplemented in time in the flushing process, flushing flow quantity is large, and the volume of the water tank can be reduced.
Description
The existing following problem of lavatory cistern ubiquity, when using water tank, water in water tank is in discharging, the flow of bath can be more and more littler, making that urinal is difficult to rinse, trace it to its cause, is because water tank is a closed container, produce negative pressure during bath in the water tank, make the interior shipwreck of water tank to discharge.Address the above problem, must in time replenish air and enter water tank.
The purpose of this utility model is to provide a kind of water tank that can in time replenish air.
The purpose of this utility model is achieved in that
A kind of water tank of pressure-adjusting type voluntarily, comprise water tank, be provided with water inlet pipe and gutter in the lower end of water tank, water inlet pipe and gutter are provided with control valve, it is characterized in that also being provided with air control valve in the lower end of water tank, air control valve comprises valve body, in valve body, be provided with inner chamber and air intlet, the handing-over position of inner chamber and air intlet is provided with step, spool is housed in valve body, has air channel on the spool, the lower end of spool is provided with the sealed step face, when the sealed step face contacts with step, air control valve cuts out.
Aforesaid a kind of water tank of pressure-adjusting type voluntarily is characterized in that the sealed step face can be a taper surface, and corresponding step is the sloping platform rank.
Aforesaid a kind of water tank of pressure-adjusting type voluntarily is characterized in that the sealed step face can be the plane, and corresponding step is the platform rank.
The utility model is simple in structure, and is easy to use, owing to can in time replenish air in water-rinsing process the time, the flow of washing by water is big, and can reduce the water tank volume.
Below in conjunction with accompanying drawing structure of the present utility model is done detailed explanation
Fig. 1 is the structural representation of water tank
Fig. 2 is the structural representation of air control valve scheme one
Fig. 3 is the structural representation of air control valve scheme two
The utility model comprises water tank 1, is provided with water inlet pipe 2 and gutter 3 in the lower end of water tank 1, and water inlet pipe 2 and gutter 3 are provided with control valve.Lower end at water tank 1 also is provided with air control valve 4.
Sealed step face 11 can be a taper surface, also can be the plane.When sealed step face 11 was taper surface, corresponding step 8 was sloping platform rank (shown in figure two).When sealed step face 11 was the plane, corresponding step 8 was platform rank (shown in figure three), at this moment, can increase sealing ring 12 at sealed step face 11 positions.
The utility model is closed control valve and the control valve of opening on the water inlet pipe 2 on the gutter 3 earlier in use, makes to be full of water in the water tank, and at this moment, because the effect of the interior hydraulic pressure of water tank and the effect of air conditioning valve core weight, air control valve cuts out.When wash by water in the lavatory, cistern water-discharging descends hydraulic pressure, produces negative pressure, and at this moment, under the effect of atmospheric pressure, the spool that air backs down air control valve enters water tank, eliminates the influence of negative pressure, and the water in the water tank can in time be discharged.
