The utility model is mainly characterized in that the utility model is provided with a pressure tank, a one-way valve, a pressure switch, and an air cleaner; the inside of the pressure tank is provided with a bent pipe; the bent pipe is provided with a water outlet at one end outside the pressure tank; the one-way valve is connected with a water inlet pipe, and a multipurpose valve is arranged between the one-way valve and the water inlet pipe. Compared with the existing domestic water supply device, the utility model has the advantages of simple structure, easy fabrication, low cost, high safety, full seal, no pollution, long service life, convenient installation and maintenance, etc.

Description

The fully-automatic household water supplying apparatus

The utility model belongs to the water supply installation technical field, is a kind of fully-automatic household water supplying apparatus.

At present, China adopts water tower, high level water tank to supply water in unconditional place of using tap water mostly, and small town, outskirts of a town, rural area, most of winch, hand and water intaking or the little water pump of using in outlying district directly supply water.Utility model patent: a kind of novel elastic water pressurizing device, the patent No. 90204070 is applied to family expenses at first and supplies water, and this patent is a kind of elastic force setting-out method of utilizing, in giving water pot, establish compression spring and barrier film, utilize the springback compressed septum, reach the purpose of setting-out, but this water pressurizing device, exist and start frequently, the back water storage that has a power failure is few, is difficult to make defectives such as maintenance trouble.

The purpose of this utility model is a kind of simple in structure, easy to manufacture, family expenses water supplying apparatus that adult is low, safe and reliable of design.

The technical scheme that the utility model is taked is to have pressurized tank, be provided with bend pipe in jar, bend pipe is provided with delivery port, one way valve, pressure switch at an end of pressurized tank outside, and one way valve links to each other with water inlet pipe, is provided with many with valve, air filter between one way valve and water inlet pipe.

Because the novel technique scheme of having taked of this reality compares with existing domestic water supply plant, have simple in structure, easy to manufacture, cost is low, safe and reliable, totally-enclosed, pollution-free, long service life is convenient to advantages such as installation and maintenance.

Following structure accompanying drawing and example are described further architectural feature of the present utility model.

Fig. 1 is a general assembly structural representation of the present utility model.

Referring to Fig. 1, the utlity model has pressurized tank 1, be provided with bend pipe 2 in the pressurized tank 1, bend pipe 2 is provided with delivery port 3 at an end of pressurized tank 1 outside, one way valve 4, pressure switch 5, the other end of bend pipe 2 is located at the bottom of pressurized tank 1, so that the water in jar can be discharged more fully, one way valve 4 links to each other with water inlet pipe 6, between one way valve 4 and water inlet pipe 6, establish many with valve 7, air filter 8, many can blowdown with valves 7, and when pressurized tank 1 internal gas pressure is not enough, can carry out tonifying Qi, the top of pressurized tank 1 is provided with pressure meter 9, when the water shortage in the pressurized tank 1, when promptly jar internal gas pressure is less than external atmosphere pressure, pressure switch 5 is opened automatically, water is promptly by water inlet pipe 6, one way valve 4, bend pipe 2 enters in the pressurized tank 1, and when the water yield in the jar reached a certain amount of, pressure switch 5 was closed automatically, like this, water just flows out from delivery port 3, supplies with people and uses, if when the water level at water source is dark, water inlet pipe 8 directly links to each other with electric pump, baroswitch 5 starts electric pump, and water delivery is to pressurized tank 1, and turn on pump supplies water, water level increases in jar, simultaneously how every turn on pump once will cross the air that filters by air filter 8 with valve 7, in covering jar in jar, when the standby water of storage foot and compressed tanks gas reach setting pressure, air pressure is opened and 5 is stopped automatically, and one way valve 4 is closed simultaneously, prevents to recharge, when making water, drawdown in the pressurized tank, volume of air increases, and pressure reduces, baroswitch 5 starts electric pump and supplies water once more, so circulation reaches the purpose of continuous water supply, if when water level is more shallow, self priming pump 10 can be set between water inlet pipe 6 and water source, without bottom valve 11 only needs before using without bottom valve 11 is filled clear water and can be used.

Claims (2)

1, a kind of fully-automatic household water supplying apparatus, it is characterized in that having pressurized tank, be provided with bend pipe in the pressurized tank, bend pipe is provided with delivery port, one way valve, pressure switch at an end of pressurized tank outside, one way valve links to each other with water inlet pipe, is provided with many with valve, air filter between one way valve and water inlet pipe.

2, a kind of fully-automatic household water supplying apparatus according to claim 1 is characterized in that being provided with self priming pump between water inlet pipe and the water source, without bottom valve.
