Description
Technical field
The utility model relates to a kind of for petroleum pipeline, natural gas line, and the safety corridor of underground waterpipe, specifically, relates to a kind of safety anti-explosive pipeline.
Background technique
In prior art, common pipe does not have good safety measure, and pipeline pressure can not obtain pressure release effectively, very easily causes pipeline burst.According to statistics, China because pipeline superpressure is exploded the accident caused, causes direct economic loss more than one hundred million, meanwhile, also makes citizen's life be subject to serious threat every year.
Therefore, research and development are a kind of safe and reliable, can stop the pipeline of superpressure blast, just become the important topic of those skilled in the art.
Model utility content
The purpose of this utility model is to overcome above-mentioned defect, the explosion-proof pipeline of new type of safe providing a kind of structure simple, with low cost and safe and reliable.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Safety anti-explosive pipeline, comprise main pipeline, described main pipeline is also at least provided with the superpressure lateral that an one end is communicated with it, the joint of described superpressure lateral and described main pipeline is provided with the valving for controlling connected state therebetween, the other end port of described superpressure lateral is provided with the decompression cover that can be used for this port of shutoff, and described decompression cover is connected by the pipe shaft of spring with described superpressure lateral.
Preferably, described main pipeline is natural gas line, petroleum pipeline or drainage pipe.
Further, described valving comprises valve switch and flashboard, and wherein, described flashboard is disc, its one side towards main pipeline is provided with at least two in fan-shaped buffering depressed part, and all buffering depressed parts are spliced to form mate with flashboard discoid.
Further, also projection is provided with in the center of the one side towards main pipeline of described flashboard.
Compared with prior art, the utility model has following beneficial effect:
(1) the utility model is provided with some superpressure laterals on main pipeline, when main pipeline pressure is excessive, valving is opened automatically, medium (liquid in main pipeline, gas) automatically flow into superpressure lateral, after flowing into the pressure medium in superpressure lateral and acquiring a certain degree, decompression cover flicks under the effect of the pressure, complete pressure release, after pressure reduces, decompression cover is return under the effect of the restoring force of spring again, block superpressure lateral, or else have the thing of superpressure blast for this reason, more be conducive to construction, cleaning, just effect of maintenance.
(2) in the utility model, the flashboard of valving is provided with buffering depressed part in the one side of main pipeline, be attached to the projection of flashboard center simultaneously, when media impingement in main pipeline is to buffering depressed part, eddy current can be formed, thus reduce the impact of medium to flashboard, ensure that the sealability of flashboard, extend its working life.

Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the schematic diagram that in the utility model, decompression cover flicks pressure release.
Fig. 3 another kind of structural representation of the present utility model.
Fig. 4 the third structural representation of the present utility model.
Fig. 5 is the partial schematic diagram of flashboard in the utility model.
In above-mentioned accompanying drawing, the component names that reference character is corresponding is as follows:
1-main pipeline, 2-superpressure lateral, 3-valving, 4-decompression cover, 5-spring, 31-valve switch, 32-flashboard, 33-cushions depressed part, and 34-is protruding.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and mode of execution of the present utility model includes but not limited to the following example.
Embodiment
As shown in Fig. 1 to 5, present embodiments provide a kind of safety anti-explosive pipeline, it mainly comprises main pipeline 1 and superpressure lateral 2, wherein, the main circulation duct that main pipeline 1 transports for medium, it is natural gas line, petroleum pipeline or drainage pipe, and the material of main pipeline is not particularly limited, and it can according to the existing pipeline of employing.Superpressure lateral to be arranged on main pipeline and to be communicated with it, its role is to, when main pipeline internal pressure is excessive, plays the effect to medium shunt in main pipeline.According to actual needs, superpressure lateral can be one, two, three even more.
Superpressure lateral 2 and the joint of main pipeline 1 are provided with the valving 3 for controlling connected state therebetween, the other end port of superpressure lateral 2 is provided with the decompression cover 4 that can be used for this port of shutoff, and decompression cover 4 is connected with the pipe shaft of superpressure lateral 2 by spring 5.By above-mentioned setting, when main pipeline pressure is excessive, valving is opened automatically, medium (liquid, gas) in main pipeline flows into superpressure lateral automatically, after flowing into the pressure medium in superpressure lateral and acquiring a certain degree, decompression cover flicks under the effect of the pressure, and medium is discharged by superpressure lateral, completes pressure release; After pressure reduces, decompression cover is return under the effect of the restoring force of spring again, blocks superpressure lateral.
In order to better realize the utility model, in the present embodiment, valving 3 comprises valve switch 31 and flashboard 32, wherein, flashboard 32 is disc, its one side towards main pipeline 1 is provided with at least two in fan-shaped buffering depressed part 33, and all buffering depressed parts 33 are spliced to form mate with flashboard 32 discoid; Meanwhile, protruding 34 are also provided with in the center of the one side towards main pipeline 1 of flashboard 32.By above-mentioned setting, during buffering depressed part in main pipeline on media impingement flashboard, be attached to the projection of flashboard center, MEDIA FLOW (liquid, gas) can form eddy current, thus reduce the impact of medium to flashboard, ensure that the sealability of flashboard, extend its working life.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on above-mentioned design principle; for solving same technical problem; even if some making on architecture basics disclosed in the utility model are without substantial change or polishing; the essence of the technological scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
