The beneficial effects of the utility model：Water supply installation of the present utility model, by ejector by water intaking valve, storage tank with Boiler couples together, water intaking valve open when, current through ejector flow into boiler, simultaneously bypass ports produce negative pressure from And suck the water in storage tank in boiler, after boiler is full of water, the water of boiler is back in storage tank and makes its liquid Face is highly reduced, it is to avoid water is gone out from outlet water clock because of expanded by heating, in addition, when the water emptying in storage tank, Sealing float can be close to water outlet through hole, plays the effect of closure water outlet through hole, it is to avoid air is through water outlet through hole entrance boiler Produce air-water mixture, structure is practical reliable.

Brief description

Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.

Fig. 1 is overall structure diagram of the present utility model；

Fig. 2 is the overlooking the structure diagram of storage tank in this utility model；

Fig. 3 is the cross-sectional view in B-B direction in Fig. 2.

Specific embodiment

As shown in figure 1, a kind of water supply installation of band anti-aqueous vapor mixed structure of this utility model offer, including boiler 1 With water intaking valve 3, boiler 1 is provided with heat-generating pipe 13, water inlet 11 and outlet 12, and water inlet 11 is connected with water intaking valve 3, in water inlet Be provided with ejector 4 between valve 3 and water inlet 11, the water inlet end of this ejector 4 is connected with water intaking valve 3, the water side of ejector 4 with Water inlet 11 connects, and the bypass ports of ejector 4 are connected with storage tank 2, is provided with water outlet through hole 21 and and water outlet in storage tank 2 The sealing float 22 of through hole 21 coupling, storage tank 2 is connected with the bypass ports of ejector 4 by water outlet through hole 21.

As shown in Figures 2 and 3, wherein, water outlet through hole 21 is conical outlet, and sealing float 22 is spherical structure, spherical Sealing float 22 can preferably mate and reaches sealing effectiveness with cone outlet.By arranging ring in the bottom of storage tank 2 Around the guardrail 23 of conical outlet arrangement, it is provided with out water space between guardrail 23, spherical sealed float 22 is placed in guardrail 23 institute Around region in, guardrail 23 have guided globe seal float 22 to water outlet through hole 21 effect.

During work, water intaking valve 3 is opened, and current enter boiler 1 through Venturi tube ejector 4, simultaneously in bypass ports Produce negative pressure thus also sucking the water in storage tank 2 in boiler 1, after boiler 1 fills water, water intaking valve 3 quits work, The anhydrous supplement of boiler 1 is come in, and liquid level rests at outlet 12, such as in figure location A horizontal plane.Now, storage tank 2 with Boiler 1 is connected, and the water of boiler 1 is back in storage tank 2, and final storage tank 2 is maintained an equal level with the liquid level of boiler 1, The liquid level of so boiler 1 is reduced, and makes to reserve the volume that water heating expands in boiler 1, it is to avoid water is swollen because being heated Swollen go out from outlet 12 water clock.

Spherical sealed float 22 in storage tank 2, under buoyancy, lifts with the height of liquid level, and in guardrail 23 All the time it is directed to conical outlet under effect.With the reduction of liquid level, the height of spherical sealed float 22 also reduces, and works as liquid level When being reduced to conical outlet, spherical sealed float 22 can be close to conical outlet, the spherical outside surface of spherical sealed float 22 With conical wall formed be in close contact, so, spherical sealed float 22 under self gravitation effect, with the conical water outlet degree of lip-rounding Become sealing structure, now the air in storage tank 2 cannot be discharged from water outlet through hole 21, it is to avoid water outlet produces gas-vapor mix, knot Structure is practical reliable.

Further, as shown in figure 3, arranging unhurried current baffle plate 24 in the bottom of storage tank 2, this unhurried current baffle plate 24 has stream Water breach 241, unhurried current baffle plate 24 forms unhurried current cavity 25 with the side wall of storage tank 2, when the water level in storage tank 2 is reduced to circular cone During shape outlet position, spherical sealed float 22 is placed on conical outlet, and the bottom due to spherical sealed float 22 does not have Liquid, does not have a buoyancy yet, and the remaining current in unhurried current cavity 25 flow slowly on conical outlet and to cover spherical sealed floating A part for sub 22 spheroids, the liquid covering this part sphere fills the spherical outside surface of spherical sealed float 22 and the sky of conical inboard wall Between, and downward active force is produced to spherical sealed float 22 so that the spherical outside surface of spherical sealed float 22 and conical inboard wall shape Become more closely to contact, sealing property is more preferable.

In addition drain valve 5 is set at the water inlet 11 of boiler 1, when the water in hot water machine is not drunk for a long time, leads to Cross the water that drain valve 5 is discharged in boiler 1, so advantageously ensure that the clean hygiene of drinking water.

The above, simply preferred embodiment of the present utility model, this utility model is not limited to above-mentioned enforcement The structure of mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to guarantor of the present utility model Shield scope.
