Abstract
A water conveyance pipeline used in an alpine environment with a large temperature difference comprises the water conveyance pipeline. The water conveyance pipeline used in the alpine environment with the large temperature difference is characterized in that a plurality of n-type compensators are arranged on the water conveyance pipeline at intervals, and a fixing support frame is arranged between each two compensators. Due to the facts that the n-type compensators and the fixing support frames which are matched with the n-type compensators are selected, and specific adjustment is carried out according to site characteristics, the problem that instability and even destruction of a water conveyance system in the alpine environment with the large temperature difference caused by expanding with heat and contraction with cold of the water conveyance system of steel pipes can be better resolved.
Description
Technical field:
The utility model relates to feedwater water delivery field, particularly under the large temperature difference environment of a kind of high mountain with the water delivery pipeline.
Background technique:
Aqueduct generally is provided underground, and ambient temperature and medium temperature change all less, so aqueduct generally need not considered the problem of expanding with heat and contract with cold.And high mountain water delivery environment is different, at first the mountain range mostly is rock, therefore can not buriedly lay, and can only make somebody a mere figurehead laying in ground, exposed tube is in environment, influenced by ambient temperature very large, naturally can produce the phenomenon of expanding with heat and contract with cold for metallic conduit, and that high Mountain area reaches four seasons difference variation round the clock is very large, stressed destroyed for fear of pipe-line system, guarantee Systems balanth, so pipeline need to consider the problem of expanding with heat and contract with cold, namely pipeline will be taked the temperature correction measure.
Secondly the mountain area physical features is wriggled, and mostly pipeline is to lay along mountain shape, and pipeline rout is irregular, can not resemble the smooth vertical and horizontal laying in plains region, will consider its particularity in the selection that compensates mode.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, use aqueduct under the large temperature difference environment of a kind of high mountain and provide, this device for cleaning pipeline is crossed the fixed support of selecting π type compensator and matching, and specifically adjust according to on-the-spot characteristics, solved well the large temperature difference environment steel pipe of high mountain water-carriage system and expanded with heat and contract with cold water-carriage system is caused this problem unstable even that destroy.
As above design, the technical solution of the utility model is: use aqueduct under the large temperature difference environment of a kind of high mountain, comprise waterline, it is characterized in that: the interval arranges a plurality of π type compensators on waterline, between per two compensators a fixed support is set.
Above-mentioned fixed support is comprised of stent support, pre-embedded steel slab and precision rest; The pre-buried pre-embedded steel slab in the top of stent support is placed precision rest on the pre-embedded steel slab, pre-embedded steel slab and precision rest are affixed, places waterline on the precision rest, and precision rest and waterline are affixed.
The above-mentioned π of stating type compensator is comprised of straight length and 90 ° of elbows.
The utlity model has following advantage and good effect:
1, the utility model is owing to π type compensator is installed at interval on body, and between per two compensators, a fixed support is set, therefore, when pipeline produces displacement because of the temperature difference, compensated by π type compensator, the extending amount of scope between its both sides fixed support of compensator compensates, by π type compensator and support bracket fastened synergy, eliminate aqueduct and produced the impact that the amount of expanding with heat and contract with cold may cause water-carriage system because of the temperature difference, the phenomenon of having avoided the unstable of water-carriage system even having destroyed is so that system can safe and stable operation.
2, the utility model arranges flexibly, can set as the case may be the size of π type compensator and the distance between two fixed supports.
Description of drawings:
Fig. 1 is layout schematic representation of the present utility model;
Fig. 2 is π type compensator detail drawing;
Fig. 3 is the fixed support detail drawing.
Wherein: 1-waterline, 2-π type compensator, 3-fixed support, 4-straight length, 5-90 ° elbow, 6-stent support, 7-pre-embedded steel slab, 8-precision rest.
Embodiment:
As shown in the figure: use aqueduct under the large temperature difference environment of a kind of high mountain, the interval arranges a plurality of π type compensators 2 on waterline 1, between per two compensators a fixed support 3 is set.The top pre-embedded steel slab 7 of the stent support 6 in the fixed support 3 is placed precision rest 8 on the pre-embedded steel slab 7, pre-embedded steel slab 7 and precision rest 8 welding are placed waterline 1 on the precision rest 8, and precision rest 8 also welds with waterline 1.
Working procedure of the present utility model is: after system puts into operation, pipeline system will be exposed in the physical environment, and the variation of ambient temperature will cause the steel pipeline to produce extending amount.When ambient temperature raise, waterline 1 expanded and extends, and total elongation will be divided into some sections by a plurality of fixed supports 3, and therefore when pipeline produced the expansion elongation, the pipeline of fixed support 3 these points did not produce displacement.Elongation between per two fixed supports 3 will be absorbed by π type compensator 2,2 of a of π type compensator 2, b and straight length 4 are subjected to displacement, 90 ° of elbows 5 deform, absorb elongation with this, the elongation that π type compensator 2 can bear needs to make its coupling by calculating with the actual elongation that produces.
When ambient temperature reduced, waterline 1 shrank, and total contour projector also will be divided into some sections by a plurality of fixed supports 3, formed the reverse displacement when flexible, and same fixed support 3 these points do not produce displacement.Contour projector between per two fixed supports 3 will be absorbed by π type compensator 2,2 of a of π type compensator 2, b and straight length 4 are subjected to displacement, 90 ° of elbows 5 deform, absorb contour projector with this, the contour projector that π type compensator 2 can bear needs to make its coupling by calculating with the actual contour projector that produces equally.By the expanding-contracting action of the π type compensator 2 between per two fixed supports 3, effectively absorbed the amount of deformation of system, the powerful thrust that system can not produced because expanding with heat and contract with cold is destroyed, guarantees security of system stable operation.
