Abstract
The utility model discloses a water pipe structure with the frost cracking prevention function. The water pipe structure with the frost cracking prevention function comprises a pipe casing, wherein two branch inner pipe casings are symmetrically arranged inside the pipe casing, and can be spliced to form a whole main inner pipe casing, an elastic membrane is arranged at the position of connection between the two branch inner pipe casings, reset springs are arranged between the inner wall of the pipe casing and each branch inner pipe casing in an abutting mode, the number of the reset springs is more than two, the reset springs are evenly distributed in the radial direction of the pipe casing, a first through hole is formed in the outer wall of the pipe casing, and extends to the branch inner pipe casings, a sealing plug is arranged inside the first through hole, and a second through hole is formed in the middle of the sealing plug. Due to the fact that the branch inner pipe casings and the elastic membrane are arranged, the water pipe structure with the frost cracking prevention function can have a certain elasticity, and the phenomenon that the main inner pipe casing cracks due to water condensation is avoided; due to the fact that the pipe casing is arranged outside the main inner pipe casing, external cold air can be resisted, if the main inner pipe casing cracks, drainage can be carried out through the second through hole, and the pipe casing arranged outside the main inner pipe casing can be effectively prevented from cracking.
Description
Technical field
The utility model relates to a kind of crack prevention water tube structure.
Background technique
Existing pipeline; especially large diameter plastic pipe is widely used in municipal engineering, hydraulic engineering, when existing plastic pipe arrives in the winter time; because water-setting build-ups ice; cause volume to increase, often can cause tube wall to break, in order to prevent water pipe from freezing crack; conventionally before need to arriving in the winter time, on water pipe, wrap up warming foam; in case water stopping tube breaks, such maintenance cost is higher, safeguards comparatively trouble.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly effectively prevents from breaking when can arrive in the winter time, and structure is comparatively simple simultaneously, and installation and maintenance is crack prevention water tube structure comparatively easily.
For addressing the above problem, the utility model adopts following technological scheme:
A kind of crack prevention water tube structure, comprise pipe box, described pipe box inside is provided with two inner tubes that are arranged symmetrically with and divides cover, after two symmetrically arranged inner tubes are divided cover splicing, a complete inner tube of formation is always overlapped, described two inner tubes divide cover joint to be provided with flexible sheet, described pipe box inwall and inner tube are divided and between cover, are had mutually Returnning spring, described Returnning spring is provided with more than two, along being radially uniformly distributed of pipe box, described pipe box outer wall is provided with one and extends to the first through hole that inner tube is divided cover, described the first through hole inside is provided with a closing cock, described closing cock middle part is provided with second through hole.
As preferred technological scheme, on the outer tube wall of described pipe box top and bottom, be provided with screw section.
As preferred technological scheme, the wall thickness of described pipe box is 3mm-5mm, and it is 1mm-2mm that described inner tube is divided the wall thickness of cover.
The beneficial effects of the utility model are: by set inner tube, divide cover and flexible sheet, make this device there is certain elasticity, prevent from causing because of hydrogenesis the total cover of inner tube to break, pipe box is externally set and can resists outside cold air simultaneously, if inner tube is always overlapped, break and can carry out draining by the second through hole, mobile shipwreck, to condense, can effectively prevent that outside pipe box from breaking, and the utility model is installed more for convenience, is applicable to promoting the use of.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of the utility model crack prevention water tube structure;
Fig. 2 is the external structure schematic diagram of the utility model crack prevention water tube structure.
Coding in figure is respectively: 1 is pipe box, and 2 divide cover for inner tube, and 3 is flexible sheet, and 4 is Returnning spring, and 5 is closing cock, and 6 is the second through hole, and 7 is screw section.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As depicted in figs. 1 and 2, this crack prevention water tube structure, comprise pipe box 1, described pipe box 1 inside is provided with two inner tubes that are arranged symmetrically with and divides cover 2, after two symmetrically arranged inner tubes are divided cover 2 splicings, a complete inner tube of formation is always overlapped, described two inner tubes divide cover 2 joints to be provided with flexible sheet 3, described pipe box 1 inwall divides between cover 3 and has mutually Returnning spring 4 with inner tube, described Returnning spring 4 is provided with more than two, along being radially uniformly distributed of pipe box 1, described pipe box 1 outer wall is provided with one and extends to the first through hole (not shown) that inner tube is divided cover, described the first through hole inside is provided with a closing cock 5, described closing cock 5 middle parts are provided with second through hole 6.
Wherein, on the outer tube wall of described pipe box 1 top and bottom, be provided with screw section 7.
The wall thickness of described pipe box 1 is 3mm-5mm, and it is 1mm-2mm that described inner tube is divided the wall thickness of cover 2.
The beneficial effects of the utility model are: by set inner tube, divide cover and flexible sheet, make this device there is certain elasticity, prevent from causing because of hydrogenesis the total cover of inner tube to break, pipe box is externally set and can resists outside cold air simultaneously, if inner tube is always overlapped, break and can carry out draining by the second through hole, mobile shipwreck, to condense, can effectively prevent that outside pipe box from breaking, and the utility model is installed more for convenience, is applicable to promoting the use of.
