Detailed description of the invention
The core of the present invention is to provide a kind of pressure piping, and this pressure piping can effectively prevent the transmission of vibration, it is to avoid the generation of particularly serious security incident。
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail。
Refer to the schematic diagram of the pressure piping that Fig. 3 and Fig. 4, Fig. 3 provide for the embodiment of the present invention；Fig. 4 be in Fig. 3 B-B to sectional view。
The present invention provides a kind of pressure piping, and including pipeline body 3, pipeline body 3 is positioned at pipe trench 7；In order to realize fixing reliable in pipe trench 7 of pipeline body 3, being provided with trocar sheath 9 at the outer ring sleeve of pipeline body 3 herein, and have gap between the outer ring of pipeline body 3 and trocar sheath 9, this gap is used for filling hardwood holder 10。
The pipeline body 3 filling hardwood holder 10 is fixed on support of pipelines 5 by pipe collar 12, and fills up fine sand 11 in pipe trench 7。Outside pipe trench 7, it is earth, in other words, among earth, has dug pipe trench 7, and the cross section of pipe trench 7 can be T-shaped or other shapes。
Adopt mode as set above so that pipeline body 3, trocar sheath 9 and hardwood holder 10 three are fixed as an entirety, and utilize pipe collar 12 that three is fixed on support of pipelines 5, so that it is guaranteed that the use of pipeline body 3 is reliable。So, the vibration of pipeline body 3 can disappear along with hardwood holder 10, trocar sheath 9, support of pipelines 5 and fine sand 11, thus making the vibration of pipeline body 3 be completely eliminated, it is to avoid the transmission of vibration, so just it can be avoided that the generation of severe and great casualty。
Specifically support of pipelines 5 is set to following form herein；Support of pipelines 5 includes horizontal part and vertical portion, and horizontal part is used for placing trocar sheath 9, and vertical portion is positioned at the lower section of horizontal part, for support level portion。
So contribute to the uniform force of support of pipelines 5, it is ensured that what pipeline body 3, trocar sheath 9 and hardwood holder 10 three were stable is fixed on support of pipelines 5, it is achieved pipeline body 3 life-time dilatation。According to practical experience, it is preferable that support of pipelines 5 is set to π font, the support of pipelines 5 of π font can more efficiently extend the service life of support of pipelines 5。
Can be connected by fixing bolt 6 is fixing between trocar sheath 9 and horizontal part, as shown in Figure of description 4。Certainly, according to actually used situation, between trocar sheath 9 and horizontal part, connected mode can also be other, will not repeat herein herein。
The horizontal part both sides of support of pipelines 5 and the sidewall of pipe trench 7 fit tightly。It is to say, the structure in order to ensure support of pipelines 5 is reliable, by the both sides of the horizontal part sidewall tightly against pipe trench 7 so that the relative position between horizontal part and pipe trench 7 immobilizes, thus effectively guaranteeing the fixing reliable of pipeline body 3。
The bottom of the vertical portion of support of pipelines 5 and pipe trench 7 fits tightly；Namely, support of pipelines 5 is positioned over the bottom of pipe trench 7, utilizes vertical portion that support of pipelines 5 is placed on the bottom of pipe trench 7 so that support of pipelines 5 cannot continue to sink along the depth direction of pipe trench 7, so that it is guaranteed that the invariant position of support of pipelines 5, further ensure that the position of pipeline body 3 is fixed。
In order to optimize the structure of pressure piping further, herein the gap uniformity between trocar sheath 9 and pipeline body 3 is arranged；That is, in order to fill the gap uniformity setting of hardwood holder 10 between trocar sheath 9 and pipeline body 3；The cross section of the pipeline body 3 being arranged with trocar sheath 9 is circular, gap uniformity between trocar sheath 9 and pipeline body 3, so that hardwood holder 10 is filled between trocar sheath 9 and pipeline body 3 uniformly, so that it is guaranteed that the Stability Analysis of Structures of pipeline body 3, improve the stability of pressure piping further。
The top of pipe trench 7 is provided with trench cover 8, thus avoiding the spilling of fine sand 11 in pipe trench 7, it is achieved in pipe trench 7, associated components stablizes, it helps avoid the environmental pollution caused because of the spilling of fine sand 11。
Preferably pipeline body 3 is positioned at 1/2 to 3/4 place of the height of pipe trench 7 herein。According to practical experience, the height and position that pipeline body 3 is positioned at pipe trench 7 makes further optimization, thus contributing to the shockproof effect of riser tubing body 3, and the pipeline body 3 being positioned at this height can also contribute to the work such as installation and maintenance。
Pipeline body 3 also includes end, for being connected with compressibility 1 and cryogenic system 2 respectively。It should be evident that be connected to pipeline body 3 between compressibility 1 and cryogenic system 2, thus realizing production and the transmission of natural gas。
Pipe trench 7 is stretched out at the both ends of pipeline body 3, and extends along the length direction of pipe trench 7。Owing to compressibility 1 and cryogenic system 2 are generally disposed at the two ends of pipe trench 7 length direction, therefore after pipe trench 7 is stretched out at the both ends of pipeline body 3, length direction along pipe trench 7 extends and is connected with cryogenic system 2 with compressibility 1 respectively, thus realizing the connection of compressibility 1 and cryogenic system 2, it is achieved the production of natural gas and transmission。
Above pressure piping provided by the present invention is described in detail。Principles of the invention and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method and the core concept thereof of the present invention。It should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to the present invention carries out some improvement and modification, these improve and modify in the protection domain also falling into the claims in the present invention。
