Abstract

The utility model discloses an anti-freezing device for tap water. The end of the existing horizontal water pipe of the tap water is connected with a triplet; the right and the left ends of the triplet are connected with the horizontal water pipes; the lower port of the triplet is connected with an air collection barrel; the inside of the air collection barrel is welded with an air delivery pipe; the upper part of the air delivery pipe is provided with a rubber pad which is used to move up and down; the lower part of the rubber pad is provided with a vent hole; the outside of the vent hole is provided with an air hole opening and closing door. The utility model is suitable for the tap water system of high pressure vessel automatic water-supply to use.

Description

Antifreezing device for water tap

The utility model relates to a kind of tap water anti-freezing device, and particularly the rural area high pressure is irritated the defroster that automatic water-supply uses, and belongs to the protector that use in the water supply field.

At present, the northern China Rural water supply is generally energy-saving high pressure and irritates automatic water-supply.During to winter,, then adopt interim Timing water supply in order to save the energy, like this, when owner forgets when water stopping time is turned on water tap venting backwater, will cause that water freezes in time pipeline, when serious water pipe or water tap bursting by freezing frozen and collapse, cause waste, even can't supply water.

The purpose of this utility model is to be to overcome above-mentioned the deficiencies in the prior art part a kind of not frozen pipe road is provided, automatic backwater, the tap water anti-freezing device at saving water source.

The purpose of this utility model is achieved in that the utility model comprises the tap water horizontal water tube, distal portion at horizontal water tube connects a threeway, and the two ends, the left and right sides of threeway are fixed on the horizontal water tube, the arm that connects suitable for reading of threeway, be connected to the gas collection bucket on the arm, in the gas collection bucket appendix be installed.

The purpose of this utility model can also reach by following measure, and in order to reach antifreezing effect, the bottom of appendix is provided with sealing mat, and the lower end of sealing mat is provided with taper air vent and stomatal movement door, and appendix is welded on the bottom of gas collection bucket.

The explanation of accompanying drawing drawing:

Fig. 1 is the utility model structural representation.

Fig. 2 is the appendix structural representation.

Gas collection bucket (1) among the figure, appendix (2), sealing mat (3), stomatal movement door (4), air vent (5).

Embodiment describes the utility model in detail below in conjunction with accompanying drawing.

In threeway of the terminal installation of tap water horizontal water tube, the two ends, the left and right sides of threeway are fixed on the horizontal water tube respectively, the arm that connects suitable for reading of threeway, connect an iron sheet gas collection bucket (1) on the arm, the tip side of arm and gas collection bucket (1) is tight with the soldering sealing, and appendix (2) welds together with the connecting portion of gas collection bucket (1).There is a taper air vent (5) lower end of appendix (1), and the aperture of air vent (5) is φ 0.8mm, and a rubber pad (3) is arranged at the top of air vent (5), and air vent is outward a stomatal movement door (4).

The course of work of the present utility model is: before discharging water water tap is closed, water one, time ducted air (also having the air in the part trunk line) and part hydraulic pressure are reduced in the iron gas storage barrel, at this moment, air will be pressed on rubber rubber cushion (3) on the bellmouth, and whole metal bucket is in and the extraneous state that does not communicate.Drawdown in the metal bucket, because the effect of hydraulic pressure and air vent, air can not be excessive.When not discharging water, the horizontal plane in the metal bucket rises and forms the pulsation balance gradually.

Cut off the water when being backwater, compressed air in the metal bucket returns time ducted hydraulic pressure to trunk line, and it is normal that pressure is replied, during beginning compressed air, the part of may running away air, make time ducted water can not get back to trunk line, at this moment trunk line is a negative pressure comprehensively, adds the deadweight of water in time pipeline, as long as water level is a decline slightly, gas in the dust-collecting bucket (1) will be opened rubber pad (3) like a cork, with time ducted water emptying, thereby reaches goal of the invention.

Than Xian You technology, the utlity model has Yi Xia You point:

1, simple in structure, reasonable in design;

2, automatic water-returning, not frozen pipe road;

3, good freezing protection effect, the scope of application is extensive;

4, save the water source, operating cost is cheap.

Claims

1, a kind of tap water anti-freezing device comprises that the end of tap water horizontal water tube is connected to a threeway, and the two ends, the left and right sides of threeway are fixed on the horizontal water tube, and the arm that connects suitable for reading of threeway is connected to the gas collection bucket on the arm, in the gas collection bucket appendix is installed.

2, tap water anti-freezing device according to claim 1 is characterized in that the bottom of appendix is provided with sealing mat, and the lower end of sealing mat is provided with taper air vent and stomatal movement door.
