Abstract
The utility model relates to a house-hold water-supplying apparatus for life, which comprises a water pump and a sealed container which are used in the prior art, and a water inlet and outlet apparatus and a pressure switch, wherein, a pressure meter and an inflating apparatus are arranged on the wall face of the sealed container or the wall of a water pipe communicated with the sealed container. The inflating apparatus additionally arranged on the sealed container can make the house-hold water-supplying apparatus for life provided with pressure higher than atmospheric pressure in advance before the utility model is used, after water enters the utility model, the pressure is increased, when the water is used, the pressure switch is started until the water nearly flows out so that the water enters the utility model again, so the utility model can raise actual water consumption between the one-step on-off of power under the condition of not enlarging the volume of the sealed container, and on the other hand, the utility model has the advantages of simple structure, easy production and low cost.
Description
The utility model relates to the family life water supply installation.
In the relatively more rich and rural area of obstructed tap water again, in order to improve quality of life, use a cover family automatic ground water supply installation, it is in demand that well water or pool water pressure-raising are become tap water.Way of the prior art is that a small pump and is cascaded in order to the airtight container that is filled with water, and a pressure switch is installed on airtight container comes the switching electricity of control of pump, to realize automatic water-supply.Its principle is: water pump is during towards airtight container pump water, and the air in the container is compressed, and hydraulic pressure is constantly raise, and when hydraulic pressure was increased to certain value, the pressure switch auto-action also cut off pump power, and water pump stops pump water; During water, the compressed air in the airtight container expands, and hydraulic pressure descends gradually, and when it dropped to certain value, the pressure switch auto-action was also opened pump power, and water pump is pump water again.The weak point of this water supply installation is: the volume of the actual water volume that can be utilized between switching electricity of water pump only accounts for the very little part of airtight container volume, is 2kgf/cm as outage hydraulic pressure
2, the energising hydraulic pressure be 1kgf/cm
2, then the volume of actual water volume that can be utilized only is the sixth of airtight container volume between switching electricity.This deficiency is understood the frequent movement of build-up of pressure switch and water pump, has not only significantly reduced their application life, also makes troubles to living water use.
The purpose of this utility model is, overcomes the deficiencies in the prior art, provides a kind of under the situation that does not enlarge the airtight container volume, can significantly improve the home-use ground automatic water supply device of actual water volume that can be utilized between switching electricity.
The purpose of this utility model is realized by following mode.
Home-use big volume ratio described in the utility model ground automatic water supply device, comprise water pump, airtight container and Inlet and outlet water device, the pressure switch used in the prior art, it is characterized in that described airtight container wall or the water wall that is attached thereto are provided with a pressure meter and an inflatable apparatus.
Compared with prior art, big volume ratio described in the utility model ground automatic water supply device, the function that not only can keep automatic water-supply in the prior art, and owing to set up aerating device on the described airtight container, it is preset with before use is higher than atmospheric pressure, water inlet back pressure increases, the smooth and easy outflow of water energy during water, the restart pressure switch is intake it again when approaching stream, thereby can significantly improve the actual water volume that can be utilized between the power on/off under the situation that does not strengthen the airtight container volume one time; On the other hand, its structure is still simple, makes easily, and is with low cost.
Be further described below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of a kind of embodiment of home-use big volume ratio described in the utility model ground automatic water supply device.
Among the figure, (2) be water pump, it is installed on the inlet channel (1), (3) be airtight container, (4) for being installed in pressure switch on the airtight container, it changes according to the pressure in the container and comes control of pump to open, and (5) be the pressure meter in order to mensuration airtight container internal gas pressure, (6) be bicycle tyre valve inside in the prior art, it is installed on the outlet conduit (7).This device is before using for the first time, in airtight container, inflate via valve inside with common inflator earlier, be increased to setting value until its internal gas pressure (being shown by pressure meter) and open water pump again, make its setting value a little less than starting mode of pump pressure usually, the existence of internal gas pressure can make the smooth and easy outflow of water.When water pump starts at every turn like this, the water amount in the airtight container seldom, so the ratio of the actual water volume that can be utilized between power on/off and the volume of airtight container can be significantly improved.As still with above-mentioned outage hydraulic pressure 2kgf/cm
2, energising hydraulic pressure 1kgf/cm
2Situation is an example, and the actual water volume that can be utilized of the utility model between a power on/off is 1/3rd of airtight container volume, is two times of prior art.
Claims (1)
1. home-use big volume ratio ground automatic water supply device, comprise water pump, airtight container and Inlet and outlet water device, the pressure switch used in the prior art, it is characterized in that described airtight container wall or the water wall that communicates with it are provided with a pressure meter and an inflatable apparatus.
