Abstract
It is plugged with a metal inner pipe in the same direction the present invention relates to a kind of antifreezing water pipe, including outer tube, in outer tube；The outer diameter of metal inner pipe is less than the internal diameter of outer tube, to form water passage between metal inner pipe and outer tube；The lumen of metal inner pipe and the lumen of outer tube mutually separate, in segment dislocation one anhydrous crumple space of metal inner pipe；The compression resistance of metal inner pipe is less than the compression resistance of outer tube so that ponding in water passage to the cold freezing and expansion when be able to discharge tension and metal inner pipe is inwardly compressed, to guarantee the integrity of outer tube.The configuration of the present invention is simple, advantage low in cost, easy for installation, antifreezing effect is good.
Description
Technical field
The present invention relates to water pipes, and in particular to a kind of antifreezing water pipe suitable for the north.
Background technique
To prevent water pipe from freezing crack, the water pipe of northern cold zone generally use outsourcing insulating layer, water wall is heated,
Or water pipe is embedded to inferior antifreezing measures, but no matter which kind of above-mentioned means, have the defects that at high cost, antifreezing effect is poor.
Summary of the invention
The invention discloses a kind of antifreezing water pipes, it is intended to improve above-mentioned deficiency present in the antifreeze means of water pipe tradition.
Present invention employs following technical solutions:
A kind of antifreezing water pipe, including outer tube are plugged with a metal inner pipe in outer tube in the same direction；The outer diameter of metal inner pipe is small
In the internal diameter of outer tube, to form water passage between metal inner pipe and outer tube；The lumen phase of the lumen of metal inner pipe and outer tube
Mutually partition, so that the anhydrous crumple space of the segment dislocation of metal inner pipe one；The compression resistance of metal inner pipe is less than the resistance to of outer tube
Pressure so that ponding in water passage to the cold freezing and expansion when be able to discharge tension and metal inner pipe is inwardly compressed, from
And guarantee the integrity of outer tube.
Preferably, the end sealing of metal inner pipe is prevented so as to mutually separate between its lumen and the lumen of outer tube
Only the water in outer tube enters in its pipe.
Preferably, the pipe end of metal inner pipe is plugged with sealing pipe close.
Preferably, the ratio between sectional area between metal inner pipe and outer tube is not less than 1:10, is not more than 1:15.
Preferably, the inside and outside differential pressure ratio of metal inner pipe is not less than 1:3.
Metal inner pipe of the invention can provide an inside expansion space when the ponding in outer tube freezes to the cold, with
Dissolve ice cube to the pressure of outer tube, protection outer tube will not be damaged by ice cube extruding, has of simple structure and low cost, installation
Advantage convenient, antifreezing effect is good.
Detailed description of the invention
Fig. 1 is the general structure schematic diagram of the embodiment of the present invention.
Specific embodiment
The present invention will be described in the following with reference to the drawings and specific embodiments.
As shown in Figure 1:
A kind of antifreezing water pipe, including outer tube 1 are plugged with a metal inner pipe 2 in outer tube 1 in the same direction.
The outer diameter of metal inner pipe 2 is less than the internal diameter of outer tube 1, to form water passage 3 between metal inner pipe 2 and outer tube 1.
The pipe end of metal inner pipe 2 is plugged with sealing pipe close 4, so that metal inner pipe 2 and outer tube 1 mutually separate, to make gold
Belong to segment dislocation one anhydrous crumple space of inner tube 2.
The ratio between section area of a circle of section area of a circle of metal inner pipe 2 and outer tube 1 is 1:10, so that the antifreezing water pipe can be through
By 9 times of expansions of 3 internal water accumulation of water passage.
The inside and outside differential pressure of metal inner pipe 2 is not less than 1:3.
The compression resistance of metal inner pipe 2 is less than the compression resistance of outer tube 2, so that ponding in water passage 3 freezing and expansion to the cold
When be able to discharge tension and metal inner pipe 2 are inwardly compressed, to guarantee the integrity of outer tube 1.
When normal water supply, water is flowed via water passage 3, and the water freezeout in water pipe will not occur at this time；And work as
Stopping after supplying water, manages interior meeting there are static ponding, ponding is expanded vulnerable to cold junction ice, and ice cube is squeezed to inward-outward direction, due to
The compression resistance of metal inner pipe 2 is less than the compression resistance of outer tube 1, and ice cube becomes 2 crumple of metal inner pipe by the way that metal inner pipe 2 is inwardly compressed
Shape obtains inside expansive space, to dissolve the extruding force to outer tube 1, forms the protection to outer tube 1.It will damage afterwards
Metal inner pipe 2 replace, can normal use again.
