Specific embodiment
The core of the present invention is to provide a kind of pressure piping, which can effectively prevent the transmission of vibration,
Avoid the generation of particularly serious safety accident.
In order to which those skilled in the art is made to more fully understand the present invention program, below in conjunction with the accompanying drawings and it is embodied
The present invention is described in further detail for mode.
It please refers to Fig.3 and the schematic diagram of pressure piping that Fig. 4, Fig. 3 are provided by the embodiment of the present invention；Fig. 4 is A- in Fig. 3
A to sectional view.
The present invention provides a kind of pressure piping, and including pipeline body 3, pipeline body 3 is located in pipe trench 7；In order to realize pipe
Fixation of the road ontology 3 in pipe trench 7 is reliable, is arranged with outer tube 9 in the outer ring of pipeline body 3 herein, and pipeline body 3
There is gap, which is used to fill hardwood support 10 between outer ring and outer tube 9.
The pipeline body 3 of filling hardwood support 10 is fixed on by pipe collar 12 on support of pipelines 5, and filled up in pipe trench 7
Fine sand 11.It is soil except pipe trench 7, in other words, pipe trench 7 has been dug among soil, and the cross section of pipe trench 7 can be
T-shaped or other shapes.
Using mode is set as above so that pipeline body 3, outer tube 9 and 10 three of hardwood support fix and are integral, and
And three is fixed on support of pipelines 5 using pipe collar 12, so that it is guaranteed that the use of pipeline body 3 is reliable.So, pipeline sheet
The vibration of body 3 can disappear with hardwood support 10, outer tube 9, support of pipelines 5 and fine sand 11, so as to enable pipeline body 3
Vibration completely eliminates, and avoids the transmission of vibration, just can avoid the generation of severe and great casualty in this way.
Support of pipelines 5 is specifically set as following form herein；Support of pipelines 5 includes horizontal part and vertical portion, horizontal part
For placing outer tube 9, vertical portion is located at the lower section of horizontal part, for support level portion.
Contribute to the uniform force of support of pipelines 5 in this way, it is ensured that pipeline body 3, outer tube 9 and 10 three of hardwood support are steady
Fixed is fixed on support of pipelines 5, realizes 3 life-time dilatation of pipeline body.According to practical experience, preferably by support of pipelines 5
π fonts are set as, the support of pipelines 5 of π fonts can more efficiently extend the service life of support of pipelines 5.
It can be fixedly connected between outer tube 9 and horizontal part by fixing bolt 6, as shown in Figure of description 4.Certainly,
According to actual use situation, connection mode can also be other between outer tube 9 and horizontal part, will not repeat herein herein.
The horizontal part both sides of support of pipelines 5 and the side wall of pipe trench 7 fit closely.That is, in order to ensure support of pipelines 5
Structure it is reliable, by the both sides of horizontal part tightly against the side wall of pipe trench 7 so that the relative position between horizontal part and pipe trench 7
It immobilizes, so as to effectively ensure that the fixation of pipeline body 3 is reliable.
The vertical portion of support of pipelines 5 and the bottom of pipe trench 7 fit closely；That is, support of pipelines 5 is positioned over to the bottom of pipe trench 7
Support of pipelines 5 is placed on the bottom of pipe trench 7 using vertical portion by portion so that support of pipelines 5 can not continue the depth along pipe trench 7
It spends direction to sink, so that it is guaranteed that the position of support of pipelines 5 is constant, further ensures that the position of pipeline body 3 is fixed.
In order to advanced optimize the structure of pressure piping, the gap uniformity between outer tube 9 and pipeline body 3 is set herein
It puts；That is, it is set between outer tube 9 and pipeline body 3 to fill the gap uniformity of hardwood support 10；It is arranged with the pipe of outer tube 9
The cross section of road ontology 3 is in annular shape, the gap uniformity between outer tube 9 and pipeline body 3, so that hardwood support 10 is uniform
Be filled between outer tube 9 and pipeline body 3, so that it is guaranteed that the stable structure of pipeline body 3, further improves pressure piping
Stability.
The top of pipe trench 7 is provided with trench cover 8, so as to avoid the spilling of fine sand 11 in pipe trench 7, realizes phase in pipe trench 7
Close the stabilization of component, it helps avoid environmental pollution caused by due to the spilling of fine sand 11.
Pipeline body 3 is preferably located to 1/2 to 3/4 place of the height of pipe trench 7 herein.According to practical experience, to pipeline sheet
The height and position that body 3 is located in pipe trench 7, which is made, to be advanced optimized, so as to contribute to the shockproof effect of riser tubing ontology 3, and
The work such as it also is able to help to install and overhaul positioned at the pipeline body 3 of this height.
Pipeline body 3 further includes end, for being connected respectively with compressibility 1 and cryogenic system 2.It should be evident that pressure
Pipeline body 3 is connected between compression system 1 and cryogenic system 2, so as to fulfill the production and 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.Due to compressibility 1 with
Cryogenic system 2 is generally disposed at the both ends of 7 length direction of pipe trench, therefore the both ends of pipeline body 3 are stretched out after pipe trench 7, edge
The length direction for pipe trench 7 extends and is connected respectively with compressibility 1 with cryogenic system 2, so as to fulfill compressibility 1 and deep cooling
The production and transmission of natural gas are realized in the connection of system 2.
Pressure piping provided by the present invention is described in detail above.Specific case used herein is to this hair
Bright principle and embodiment is expounded, the explanation of above example is only intended to help understand the present invention method and its
Core concept.It should be pointed out that for those skilled in the art, in the premise for not departing from the principle of the invention
