Abstract
The utility model relates to a high-pressure water supply pipeline with anti-freezing function, which comprises at least two high-pressure outer pipes, wherein two adjacent high-pressure outer pipes are mutually connected in a sealing way through flanges arranged at the respective pipe ends to form a closed high-pressure pipeline; the high-pressure pipeline is characterized by also comprising a metal inner pipe which is inserted in the high-pressure pipeline in the same direction; the outer diameter of the metal inner pipe is smaller than the inner diameter of the high-pressure outer pipe, so that a water passing channel is formed between the metal inner pipe and the high-pressure pipeline; the pipe end of the metal inner pipe is inserted with a sealing pipe plug so as to lead the pipe cavity of the metal inner pipe and the water passing channel to be mutually separated and form a water-free collapsing space; the pressure resistance of the metal inner pipe is smaller than that of the high-pressure outer pipe, so that the tension is released by inwards compressing the metal inner pipe when accumulated water in the water passing channel expands in the case of cold ice, and the integrity of the high-pressure outer pipe is guaranteed. The utility model has the advantages of simple structure, convenient installation and good anti-freezing effect.
Description
Technical Field
The utility model relates to a structural improvement of high pressure water supply pipeline.
Background
In order to prevent the frost cracking of the water pipe, the high-pressure water supply pipeline in the northern cold area generally adopts anti-freezing measures such as wrapping an insulating layer, heating the wall of the water pipe or burying the water pipe underground, but the above measures have the defects of high cost and poor anti-freezing effect.
Disclosure of Invention
The utility model discloses a high pressure water supply pipeline aims at improving the above-mentioned not enough that traditional high pressure water supply pipeline exists.
The utility model adopts the following technical scheme:
a high-pressure water supply pipeline with an anti-freezing function comprises at least two high-pressure outer pipes, wherein the two adjacent high-pressure outer pipes are mutually connected in a sealing way through flanges arranged at the pipe ends of the two high-pressure outer pipes to form a closed high-pressure pipeline; the high-pressure pipeline is characterized by also comprising a metal inner pipe which is inserted in the high-pressure pipeline in the same direction; the outer diameter of the metal inner pipe is smaller than the inner diameter of the high-pressure outer pipe, so that a water passing channel is formed between the metal inner pipe and the high-pressure pipeline; the pipe end of the metal inner pipe is inserted with a sealing pipe plug so as to lead the pipe cavity of the metal inner pipe and the water passing channel to be mutually separated and form a water-free collapsing space; the pressure resistance of the metal inner pipe is smaller than that of the high-pressure outer pipe, so that the tension is released by inwards compressing the metal inner pipe when accumulated water in the water passing channel expands in the case of cold ice, and the integrity of the high-pressure outer pipe is guaranteed.
The utility model discloses pass through flange mutual sealing connection with the high-pressure outer tube of difference in order to form high-pressure line, be equipped with a metal inner tube in the high-pressure line, the metal inner tube can provide an inward expansion space when ponding in the high-pressure line meets the cold knot ice to the pressure of ice-cube to high-pressure line is separated in the change, and protection high-pressure line can not be extruded by the ice-cube and damaged. The utility model has the advantages of simple structure, convenient installation and good anti-freezing effect.
Drawings
Fig. 1 is a schematic diagram of the overall structure of the embodiment of the present invention.
Detailed Description
The present invention will be described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1:
a high-pressure water supply pipeline with an anti-freezing function comprises a first high-pressure outer pipe 1, a second high-pressure outer pipe 2 and a metal inner pipe 3, wherein the first high-pressure outer pipe 1 and the second high-pressure outer pipe 2 are mutually connected in a sealing manner through a first flange 101 and a second flange 201 of flanges arranged at the pipe ends of the first high-pressure outer pipe and the second high-pressure outer pipe respectively to form a closed high-pressure pipeline, the metal inner pipe 3 is inserted into the high-pressure pipeline in the same direction, and the outer diameter of the metal inner pipe is smaller than the inner diameter of the first high-pressure outer pipe 1 and the inner diameter of the second high-pressure; the pipe end of the metal inner pipe 3 is inserted with a sealing pipe plug 5, so that the pipe cavity of the metal inner pipe 3 is mutually separated from the water passing channel 4, and the pipe cavity of the metal inner pipe 3 forms a water-free collapsing space; the pressure resistance of the metal inner pipe 3 is smaller than that of the first high-pressure outer pipe 1 and the second high-pressure outer pipe 2, so that the tension is released by inwards compressing the metal inner pipe 3 when accumulated water in the water passing channel 4 is expanded when meeting cold and frozen ice, and the integrity of the first high-pressure outer pipe 1 and the integrity of the second high-pressure outer pipe 2 are guaranteed.
After stopping supplying water, can leave static ponding in the high-pressure line, ponding is easily frozen and is expanded, and the ice-cube extrudees to inside and outside direction, because the withstand voltage of metal inner tube 3 is less than the withstand voltage of first high-pressure outer tube 1 and second high-pressure outer tube 2, and the ice-cube makes metal inner tube 3 ulcerate deformation through inside compression metal inner tube 3 to obtain inside expansion space, thereby has dissolved the extrusion force to first high-pressure outer tube 1 and second high-pressure outer tube 2, forms the protection to high-pressure line. The damaged metal inner pipe 3 is replaced afterwards, and the metal inner pipe can be used normally again.
