Description

Variable frequency non-negative pressure water
Technical field
The utility model relates to living water technical fields, and in particular to a kind of variable frequency non-negative pressure water.
Background technique
Domestic water is generally tap water or other supply equipments, often occurs that high-rise building hydraulic pressure is inadequate or power failure feelings It is anhydrous to use phenomenon under condition.If but former vacuum tank internal cause water consumption it is excessively high available without sufficient water when, it is difficult to from city planting ductwork Middle acquisition water source, therefore be also difficult to cope with the generation of this kind of emergency case.For this purpose, the utility model proposes one kind with spare The variable frequency non-negative pressure water of vacuum tank.
Utility model content
In order to overcome the shortcomings in the prior art, the utility model proposes a kind of variable frequency non-negative pressure water, including it is total Water inlet pipe, the first steady-flow tank and the second steady-flow tank;The water inlet manifold is connected with city planting ductwork, first steady-flow tank and described First pipeline is set between water inlet manifold, the second pipeline is set between second steady-flow tank and the water inlet manifold;Described One pipeline and second pipeline are equipped with the first control valve and the second control valve;On first pipeline and second pipeline Variable frequency pump is further respectively had, the water inlet manifold is equipped with pressure gauge;First control valve, the second control valve and the pressure Power meter is connected with a control cabinet.
The utility model proposes the variable frequency non-negative pressure water in, second steady-flow tank be equipped with liquidometer.
The utility model proposes the variable frequency non-negative pressure water in, be provided with filtration members on second pipeline.
The utility model proposes the variable frequency non-negative pressure water in, the liquidometer is connected with the control cabinet.
The utility model proposes the variable frequency non-negative pressure water in, further comprise with first steady-flow tank and The several groups water pump of the water outlet connection of second steady-flow tank, the water pump are equipped with air automatic exhaust steam valve, and the air is automatic Exhaust valve is connected to control cabinet.
The utility model proposes the variable frequency non-negative pressure water in, be additionally provided with vacuum on first steady-flow tank Suppressor.
Compared with prior art, the utility model has the beneficial effects that increasing by second in non-negative pressure frequency-changing water supply device surely Tank is flowed, when the situation of city planting ductwork hydraulic pressure deficiency, the second steady-flow tank and the first steady-flow tank are opened by control cabinet, and by variable frequency pump Pressurization and water delivery in first steady-flow tank in the same direction of city planting ductwork one, so as to adjust water inlet pipe pressure, in hydraulic pressure deficiency and state of cutting off the water Under can persistently be supplied water by the second steady-flow tank.
Detailed description of the invention
Fig. 1 is variable frequency non-negative pressure water structural schematic diagram in an embodiment of the present invention;
Specific embodiment
It is described in more detail below in conjunction with variable frequency non-negative pressure water of the schematic diagram to the utility model, wherein Illustrate the preferred embodiment of the utility model, it should be appreciated that those skilled in the art can modify described herein it is practical new Type, and still realize the advantageous effects of the utility model.Therefore, following description should be understood as those skilled in the art It is widely known, and be not intended as limitations of the present invention.
As shown in Figure 1, the utility model proposes a kind of variable frequency non-negative pressure water, including water inlet manifold 1, first is steady Flow tank 2 and the second steady-flow tank 3;The water inlet manifold 1 is connected with city planting ductwork, the water inlet manifold 1 and first steady-flow tank 2 Between be equipped with the first pipeline 11;The second pipeline 12 is equipped between the water inlet manifold 1 and second steady-flow tank 3.
Wherein, first pipeline 11 is equipped with the first control valve 111, and second pipeline 12 is equipped with the second control valve 121, variable frequency pump is equipped on first pipeline 11 and second pipeline 12.The water inlet manifold 1 is equipped with pressure gauge 14;First control valve 111, the second control valve 121 and pressure gauge 14 are connected with a control cabinet.
The utility model proposes variable frequency non-negative pressure water work when, control cabinet receive from pressure gauge 14 send Water inlet manifold 1 hydraulic pressure, when hydraulic pressure be higher than scheduled pressure of supply water when, the first control valve 111 and the second control valve 121 are simultaneously It opens, city planting ductwork is to 3 water flowing simultaneously of the first steady-flow tank 2 and the second steady-flow tank, and after water is full in the second steady-flow tank 3, second is controlled Valve 121 processed is closed, and the second steady-flow tank 3 enters the water storage stage.When city planting ductwork hydraulic pressure is lower than scheduled pressure of supply water, frequency conversion water Pump is opened, the several groups water pump water flowing with first steady-flow tank 2 in the same direction of city planting ductwork one, achievees the purpose that ftercompction is supplied water.
The preferred embodiment that above are only the utility model, does not play the role of any restrictions to the utility model. Any person of ordinary skill in the field, in the range of not departing from the technical solution of the utility model, to the utility model The technical solution and technology contents of exposure make the variation such as any type of equivalent replacement or modification, belong to without departing from the utility model Technical solution content, still fall within the protection scope of the utility model.
