Description
Technical field
The utility model relates to a kind of tubing, and more particularly, it relates to a kind of freeze proof tubing.
Background technique
In the winter of northern area, if having ponding in the piping outside the house, ponding is just very easy to freeze, and after freezing, the volume of water can expand, and this will cause pipeline break or occur crack.
The measure of current frost-cracking-preventing is normally at the outside of pipeline parcel thermal insulating material or discharged in time by the ponding in water pipe, such complicated construction technique, and cost is higher, and frost-cracking-preventing effect neither be fine, when temperature is too low, still bursting by freezing phenomenon can occur.
Because sewer is normally made up of the corrosion-resistant impact-resistant high-strength material of PVC, the non-constant of ductility, after water freezing, volume can expand 1/10, causes and pipe fitting can be caused to be split up, and therefore needs to solve the poor problem of tubing ductility.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of elasticity of the expansiveness of interior pipe and buffer layer that utilizes can allow the freeze proof tubing of pipe fitting internal water accumulation freezing and expansion.
For achieving the above object, the utility model provides following technological scheme: a kind of freeze proof tubing, comprise tubing body, described tubing body comprises interior pipe and outer tube, buffer layer is provided with between described interior pipe and outer tube, described interior Guan Yousi pars contractilis composition, described some pars contractilis are along the circumferential direction uniformly distributed, described pars contractilis comprises the slide plate of arc and the connecting plate of arc, described slide plate and connecting plate are staggered is between two connected to form annular, the both sides of described slide plate all penetrate adjacent connecting plate, the both sides of described slide plate are equipped with projection, the cavity slided for described projection is provided with in described connecting plate, and described projection and described cavity sidewalls clamping.
The utility model is set to further: described buffer layer is made up of lactoprene, is provided with several air bags in described buffer layer.
The utility model is set to further: described air bag quantity is 8, and is circumferentially uniformly distributed.
The utility model is set to further: described air bag is provided with the vent be in communication with the outside, and described vent runs through buffer layer and outer tube.
Compared with prior art, the utility model has the advantage of, add in one and manage, make to need the current of discharging from interior Bottomhole pressure, and interior Guan Jun is made up of pars contractilis, like this when winter, pipeline internal water accumulation froze, ponding volumetric expansion can drive the expansion of interior pipe, because slide plate can slide in connecting plate, like this by the slip of slide plate, the volume of interior pipe can be made to increase, interior pipe can be made can to bear the icing expansion of ponding, thus can not break; Owing to having a buffer layer between interior pipe and outer tube, be equivalent to the space giving interior pipe one expansion, expansion that can be suitable when ponding, ensure that the safety and stability of water pipe, and simultaneous buffering layer can eliminate the damage that water route impact water pipe causes tube wall.

Reference character: 1, outer tube; 2, buffer layer; 21, air bag; 22, vent; 31, slide plate; 311, projection; 32, connecting plate; 321, cavity.
Embodiment
Referring to figs. 1 through Fig. 3, a kind of freeze proof tubing embodiment of the utility model is described further.
A kind of freeze proof tubing, comprise tubing body, described tubing body comprises interior pipe and outer tube 1, buffer layer 2 is provided with between described interior pipe and outer tube 1, described interior pipe is made up of several pars contractilis, described pars contractilis is along the circumferential direction uniformly distributed, described pars contractilis comprises the slide plate 31 of arc and the connecting plate 32 of arc, described slide plate 31 and connecting plate 32 are staggered is between two connected to form annular, the both sides of described slide plate 31 all penetrate adjacent connecting plate 32, the both sides of described slide plate 31 are equipped with projection 311, the cavity 321 slided for described projection 311 is provided with in described connecting plate 32, and described projection 311 and the clamping of described cavity 321 sidewall.
Preferably, described pars contractilis is 4 to the present embodiment, and four pars contractilis form a circular interior pipe jointly.
Described cavity 321 is also arc, can slide for the projection 311 of described accommodation slide plate 31, can enter for 31 liters, described slide plate, the inwall of described cavity 321 only enters for described slide plate 31, so just, slide plate 31 can be utilized with coordinating of connecting plate 32, the volume of interior pipe water flowing to be increased, and projection 311 is positioned at described cavity 321 all the time, projection 311 can effectively be blocked by cavity 321 sidewall, anti-limited slip plate 31 comes off separation in cavity 321.
Pass through technique scheme, like this when winter, pipeline internal water accumulation froze, ponding volumetric expansion can drive the expansion of interior pipe, because slide plate 31 can slide in connecting plate 32, like this by the slip of slide plate 31, the volume of interior pipe can be made to increase, interior pipe can be made can to bear the icing expansion of ponding, thus can not break; Owing to having a buffer layer 2 between interior pipe and outer tube 1, be equivalent to the space giving interior pipe one expansion, expansion that can be suitable when ponding, ensure that the safety and stability of water pipe, and simultaneous buffering layer 2 can eliminate the damage that water impact water pipe causes tube wall.
Described buffer layer 2 is made up of lactoprene, is provided with several air bags 21 in described buffer layer 2.
Described air bag 21 quantity is 8, and is circumferentially uniformly distributed.
Pass through technique scheme, lactoprene itself has certain high elasticity, time when water pipe is normal, can conflict with interior pipe firmly, the impact force of current pair and water pipe can be reduced, the effect of shock-absorbing can be played by elasticity, water pipe entirety is decreased rock, loosening appears in the joint of anti-water stopping tube, leak, and the coordinating of air bag 21 and lactoprene, lactoprene local is made more to have compressibility, interior pipe can be made when expansion, can not because of the filling of lactoprene, cause and larger extruding force is produced to outer tube 1, to the inflatable elasticity of interior Guan Geng great.
Described air bag 21 is provided with the vent 22 be in communication with the outside, and described vent runs through buffer layer 2 and outer tube 1.
Preferably, the aperture of described vent 22 is less, and is positioned at the edge of air bag 21 for the present embodiment.
By technique scheme, due to through hole be compressed for air bag 21 time, discharged by the gas of air bag 21 inside, like this, the buffer layer 2 of air bag 21 is compared and is just more had compressibility with not having vent 22; And the aperture of vent 22 is smaller, foreign material stone at ordinary times can not enter; And the edge top box being positioned at air bag 21 compares and the neutral position of opening at air bag 21, if rain enters inside air bag 21 like this, can discharge timely, can not inside overstock.
