Description
Technical field
It the utility model is related to a kind of wood working tool, and in particular to the bi-layered device based on natural gas line.
Background technology
Steel pipe is the main material of pipeline.Natural gas transportation steel pipe is the more special metallurgy that plate is formed by deep processing
Product.The tissue morphology of pipe line steel, due to the difference of technology, there is certain difference in the pipe line steel of each manufacturer's production.20
In the 60's of century, X52 grade of steels typically are used, use X60, X65 grade of steel the seventies, the 80-90 ages are based on X70 steel.Foreign country one
A little national gas pipelines have started to use X80 steel.X100 has laid in the state such as continuous development, Canada studied with pipe line steel
With the test section of X120 pipe line steels.X80 levels pipe line steel is used for 7.71km by China first in the peaceful interconnection pipeline engineering in Ji
Test section.A diameter of 1219mm X80 steel-grade pipeline is all employed up to 4843km the second west to east gas pipeline project main pipeline
Steel, distribution pressure is brought up into 12Mpa.In general, X80 steel is ferrite and bainite duplex structure, and X100 pipe line steels are
Bainite structure, X120 pipe line steels are ULCB and martensite.It is intensity, tough for the tubing of natural gas line
Property and solderability are three most basic quality control indexs.
The pressure that each pipeline is born is fixed, but during practical operation, due to all pipelines
It is not that very each piece of molecular formula is all identical, send very much and easily cause to reveal in the coarse place of processing, but the length of pipeline
It is imponderable, goes to keep without so much each segment pipe personnel of arranging work of manpower and materials, causes Pipeline damage initial stage
It can not learn, all be often that situation can just be learnt when serious；And natural gas is insipid in itself, but in order to artificial
Safe handling, with the addition of hydrogen sulfide, the usage amount of present natural gas is increasing, for the main steam line in community resident building
For, gas safe is equal to life security, but existing all detection means are all in gas leakage to outside, artificial nose
Son is just handled after smelling, and causes very big delay on the time, how very first time detection natural gas line leakage
Gas situation, into the problem of a great research.
Utility model content
Technical problem to be solved in the utility model is that Pipeline damage can not be learnt initial stage, and can not be in the very first time
The gas leakage situation of natural gas line is detected, and it is an object of the present invention to provide the bi-layered device based on natural gas line, at the beginning of solving Pipeline damage
Phase can not learn, and can not be the very first time detect the gas leakage situation of natural gas line the problem of.
The utility model is achieved through the following technical solutions：
Bi-layered device based on natural gas line, including pipeline and valve, the pipeline are double-skin duct, inner tubal wall with it is outer
Include clearance layer, in addition to the pressure sensor being arranged on pipeline between tube wall；The pressure sensor include processor and
Feeler；The feeler is located inside clearance layer, sets probe apparatus in the processor connection feeler, the valve includes sensing
Device chamber and valve layer, the sensor processor to match with probe apparatus is set in the sensor cavity room；The valve layer
Including air inlet, gas outlet and joystick.Existing all detection means are all in gas leakage to outside, artificial nose
Just handled after smelling, cause very big delay on the time, how very first time detection natural gas line gas leakage
Situation, the utility model, in order to solve this problem, first employs double-skin duct design, from the degree of guarantee for, this
It is further to prevent from revealing, for practical significance, this is to detect gas leakage situation, double-deck natural gas tube in the very first time
Road, centre are by gap, and in reset condition, i.e., when in the state of not revealing, the gas in pipeline is free from hydrogen sulfide,
So the utility model, increases by one layer first on the basis of conventional monolayers pipeline, middle gap layer position is reserved, between middle
Gap layer sets probe apparatus, and probe apparatus can use minimum portable probe apparatus, detect hydrogen sulfide, once it is detected with
During hydrogen sulfide, the sensor processor to valve is sent by wireless base station apparatus, when receiving hydrogen sulfide information, starts report
Alarm device alert process, warning device here are freely set, and the utility model designs sensor processor on valve, is
Be exactly the processing for doing a sealing, avoid artificial neglectful destruction, and such position is convenient when overhauling each time
Unified detection.The main functionality of valve is constant, still passes through joystick controlled valve.The pressure that each pipeline is born is
Fixed, but during practical operation, because all pipelines are not that very each piece of molecular formula is all identical, very
Send and easily cause to reveal in the coarse place of processing, but the length of pipeline is imponderable, without so much manpower and materials
Each segment pipe personnel of arranging work go to keep, and cause Pipeline damage can not learn that the utility model is asked to solve this initial stage
Topic, using double-skin duct, the piping failure situation of interior conduit or Outer Tube can be sufficiently detected, because either interior
The damage of Outer Tube, the air pressure variations of inside can be all caused, internally air layer is clearance layer internally, passes through feeler
To detect, it can handle and show by processor after feeler detection, described processor shell carries display screen, and display is current
Pressure changing.Staff can learn change when inspection, be handled.
The layer of silica gel is seamlessly connected with inner tubal wall.Further, as preferred scheme of the present utility model, layer of silica gel sealing
Effect is fine.
The sound end of the probe apparatus is fixedly connected with the spring wire in spring layer.Further, as the utility model
Preferred scheme, this be in order to avoid probe positions are not fixed, carry way in cause to damage.
The sensor cavities include battery port and display screen, further, as preferred scheme of the present utility model, set
Display screen can more be apparent from the seriousness of leakage, and first intuitively sees hydrogen sulfide data, obtains the big of amount of leakage
It is small, second, intuitively see the position of accident pipeline, if outlet pipe, manual-lock valve, control can let out at once
Dew, if admission line, and during uncontrollable upper level supply, explained the situation at once with responding unit.
Alarm built in the pressure sensor, institute's alarm are buzzer siren.Further, as of the present utility model
Preferred scheme, can direct alert process.
The utility model compared with prior art, has the following advantages and advantages：
1st, bi-layered device of the utility model based on natural gas line, double-skin duct design is employed, from the degree of guarantee
For upper, this is further to prevent from revealing, and for practical significance, this is to detect gas leakage situation in the very first time；
2nd, bi-layered device of the utility model based on natural gas line, using double-skin duct, can sufficiently detect
The piping failure situation of interior conduit or Outer Tube, because the damage of either inside and outside pipeline, it can all cause the air pressure of inside
Power changes, and internally air layer is clearance layer internally, is detected by feeler；
3rd, bi-layered device of the utility model based on natural gas line, display screen is set more to be apparent from revealing
Seriousness, first intuitively sees hydrogen sulfide data, obtains the size of amount of leakage, second, intuitively see accident pipeline
Position, facilitate narration situation.
