Abstract

The utility model provides a running water freeze-proof device. The utility model is provided with a pipe fitting body on which an air inlet valve is arranged, and the inner cavity of the pipe fitting is communicated with the inner cavity of the air outlet end of the air-inlet valve. The freeze-proof device can be installed on a water pipe at the end of a running water outlet pipe. When the air temperature decreases in winter, the utility model can inject compressed air to a running water pipeline through the air inlet valve and can press the running water at the end of the water outlet pipe to a non-frozen zone underground, so water in the running water pipeline and a water tap can be prevented from being frozen. The utility model has the advantages of simple structure, convenient use, low expense, no consumption of any heat energy and electric energy, and good freeze-proof effect; meanwhile, the utility model has no influence on environment and the quality of the running water.

Description

The tap water anti-freezing device

Technical field

The utility model provides a kind of device that is used on the water supply pipe, especially a kind of defroster.

Background technology

In the winter of the northern area of China, people are frozen in order to prevent the water in running water pipe and the water tap, and method and the shortcoming thereof that adopts is usually: 1, wrap up terminal water pipe and water tap with thicker heat insulating material, but when temperature is very low, antifreezing effect is relatively poor, tends to cause antifreeze failure.2, water tap is opened certain aperture, allowed it do little by little without a break, this not only can waste precious water resource, and can cause near the water the unsewered water tap to build-up ice, and is not only dirty but also sliding.3, with electrically heated heating tape parcel water pipe end, though antifreezing effect is good, power consumption is many, expense height, poor stability.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of tap water anti-freezing device is provided, and it can be convenient in winter, prevent that the tap water in running water outlet pipe end and the water tap is frozen effectively.

The utility model is achieved in that the tap water anti-freezing device, and it has pipe fitting, and admission valve is arranged on the pipe fitting, and the pipe fitting inner chamber communicates with outlet side inner chamber on the admission valve.

Adopt the tap water anti-freezing device of said structure, can be installed on the terminal water pipe of running water outlet pipe.When winter, temperature reduced, compressed gas source (as bicycle pump) can be connected on the inlet end of admission valve, by admission valve injecting compressed air in water supply pipe.Compressed-air actuated pressure just can be depressed into the tap water of outlet pipe end the tabetisol band of below ground greater than the pressure of supply water of tap water.After closing water tap, just be full of air in the water pipe of running water outlet pipe end.Because of air is not congelative, thereby prevented that effectively the water in water supply pipe and the water tap is frozen.This defroster is simple in structure, and is easy to use, and expense is low, do not consume any heat energy, electric energy, and good freezing protection effect can not produce any influence to environment and tap water quality yet.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing illustrates structure of the present utility model and using method.

As shown in drawings, the tap water anti-freezing device of the utility model, it has pipe fitting (1), and admission valve (2) is arranged on the pipe fitting, and pipe fitting inner chamber (3) communicates with outlet side inner chamber (4) on the admission valve.

Described pipe fitting (1) is running water pipe, pipe collar, elbow, to the plug on silk or the fire plug.

As shown in Figure 4, escape pipe (2a) is arranged on described admission valve (2), air inlet pipe (2d) is installed together by nut (2c) and escape pipe, and valve inside rubber hose (2c) is arranged on the air inlet pipe.

Described admission valve (2) is air tube valve or other breather cheek valve.Fig. 5 has represented that a kind of admission valve is the structure of the tap water anti-freezing device of air tube valve.Admission valve on the pipe fitting (1) is made up of escape pipe (2e) and the air tube valve inside (2f) that is installed in the escape pipe.

Fig. 1, Fig. 2, Fig. 3 represented respectively pipe fitting be pipe collar, to the structure of the tap water anti-freezing device of silk, elbow, its admission valve comes down to the bicycle tube valve cock.Fig. 6 has represented that pipe fitting is the structure of the tap water anti-freezing device of the plug on the fire plug, and its admission valve comes down to the air tube valve.

During use, the tap water anti-freezing device of the utility model can be installed in running water outlet pipe end, make its part that becomes running water pipe, or admission valve is directly installed on the end of running water outlet pipe.The end running water pipe that water tap is installed should be inclined upwardly a little, in case water.Water tap preferably adopts sealing performance potsherd water tap preferably.Each parts of running water outlet pipe are also answered good seal, should not have gas leak phenomenon.

During injecting compressed air, preferably use the pedal inflator in the household tap water pipe, old man, child also can use like this.When compressed air was injected into to a certain degree, the tap of can fetching boiling water made a part of compressed air discharge through water tap, to get rid of the water in the water tap.Subsequently water tap is closed, once more injecting compressed air in running water pipe.And in the running water pipe on fire plug during injecting compressed air, can utilize the source of the gas that carries on the fire fighting truck.

Obviously, admission valve also can be other breather cheek valve, as long as outwards lose heart after its 26S Proteasome Structure and Function can satisfy air inlet and prevent air inlet.
