Abstract

An automatic anti-freezing device for water use pipeline belongs to resident water supply technology and anti-freezing technology field, especially relates to the resident water supply and water use anti-freezing technology. The utility model is characterized in that, an outer wall of the pipeline is compactly enclosed with a cylinder-shaped heat-insulating layer, a heating part made of line-shaped electrical heating materials is applied along the pipeline between the outer wall of the pipeline and the heat-insulating layer, two electrified terminals N1and L1 leaded by the heating part are correspondingly connected with N1 and L1 of a temperature controller; the outer wall of the pipeline is tightly attached to a temperature-sensing probe leaded by the temperature controller, a temperature controller power input terminal is connected with an external power supply socket. The electrical heating materials are PTC heating materials or electric-heat wires wrapped by insulation materials. The utility model has active effects; once upon the extreme low temperature (lower than -5 DEG C) weather, the outdoor pipeline and the apparatus freezing can be avoided.

Description

A kind of automatic freezing-protective device of water pipeline

Technical field

Belong to resident's hydrotechny, freezing proof technique field, exactly relate to the freezing proof technique of resident's water supply, water.

Background technology

For successive years, the weather of extreme low temperature (below 5 ℃) winter once appearred in the area, Shanghai, and the trend that occurs extreme low temperature weather will repeatedly be arranged from now on, extreme low temperature causes outdoor pipe and equipment to freeze, make resident, the lighter of unit not have living water use, the bursting by freezing of weight person's equipment, the water pipe water that breaks overflows Kingsoft what is more, cause heavy losses to the owner, going on a tour on holidays can be weighed down with anxieties.

Summary of the invention

The utility model provides that a kind of also there are the living water use supply in resident, unit when the weather of extreme low temperature (below 5 ℃) occurring, and equipment can bursting by freezing, more can water pipe break to cause water to overflow a kind of automatic freezing-protective device of water pipeline of Kingsoft situation.

The technical scheme that the utility model is taked:

A kind of automatic freezing-protective device of water pipeline, comprise pipeline, its scheme is: pipeline outer wall closely is with cylindric insulation layer, along the pipeline part of heating that the linear electric heating material makes of fitting, two energising end N1, the L1 that the part of heating is drawn hold corresponding joining with N1, the L1 of temperature controller between pipeline outer wall and the insulation layer; Pipeline outer wall is close to the temperature-sensing probe of being drawn by temperature controller, and the temperature controller power input connects external power receptacle.Described electric heating material is the PTC exothermic material, or the heating wire of being wrapped up in by insulation materials.

Good effect behind enforcement the utility model is:

In case the weather of extreme low temperature (below 5 ℃) occurs, avoided outdoor pipe and equipment to freeze, there is not living water use in that the southern resident of cold winter, unit are again anxious, do not worry that equipment bursting by freezing water overflows Kingsoft yet, also can relievedly go on a tour holiday.

The specific embodiment

Now the utility model is described in further detail in conjunction with the accompanying drawings

A kind of automatic freezing-protective device of water pipeline, comprise pipeline, it is characterized in that: pipeline 1 outer wall closely is with cylindric insulation layer 2, along the pipeline part 3 of heating that the linear electric heating material makes of fitting, two energising end N1, the L1 that the part of heating is drawn hold corresponding joining with N1, the L1 of temperature controller 4 between pipeline outer wall and the insulation layer; Pipeline 1 outer wall is close to the temperature-sensing probe 5 of being drawn by temperature controller, and the temperature controller power input connects external power receptacle 6.Described electric heating material is the PTC exothermic material, or the heating wire of being wrapped up in by insulation materials.

Claims
