Description
Technical field
It the utility model is related to a kind of concentration detection apparatus, and in particular to a kind of concentration detection apparatus of gas.
Background technology
The fast development of Natural Gas Industry of China is only the beginning of a new stage.From whole natural gas upper-lower operations unifying
System engineering from the point of view of, Natural Gas Industry of China is still young.Compared with other mature Natural Gas markets, Chinese development turn into
The used time of ripe market for natural gas will be shorter.
Gas pipeline is assembled by single cell by root.Modern collecting pipe and gas pipeline is by steel
Pipe forms through electric welding connection.Steel pipe has that seamless pipe, spiral seam pipe, straight-seam pipes are a variety of, seamless pipe be applied to caliber be 529 millimeters with
Under pipeline, spiral seam pipe and straight-seam pipes are applied to large diameter pipeline.The pipe cross-sectional configuration of gathering line, complicated is interior
Coating-steel pipe-external insulation layer-heat-insulation layer；It is simple then only steel pipe and external insulation layer, and inside coating and insulation (cold insulation)
Layer adds determination again depending on gas transmission technique.
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.
Natural gas is insipid in itself, but for artificial safe handling, with the addition of hydrogen sulfide, present natural gas
Usage amount it is increasing, for the main steam line in community resident building, gas safe is equal to life security, but existing
All detection means having just are handled after smelling, caused on the time to outside, artificial nose in gas leakage
Very big delay, how very first time detection natural gas line gas leakage situation, into the problem of a great research.
Utility model content
Technical problem to be solved in the utility model be existing all detection means be all gas leakage to outside,
Artificial nose is just handled after smelling, and very big delay is caused on the time, how in very first time detection natural gas
The gas leakage situation of pipeline is, and it is an object of the present invention to provide a kind of concentration detection apparatus of gas, solving existing all detection means is all
In gas leakage to outside, artificial nose just handled after smelling, and causes very big delay on the time, how the
One time detected the problem of gas leakage situation of natural gas line.
The utility model is achieved through the following technical solutions：
A kind of concentration detection apparatus of gas, including pipeline and valve, the pipeline are double-skin duct, inner tubal wall successively to
It is upper to include layer of silica gel, spring layer and outer tube wall, probe apparatus is set in the spring layer, the valve include sensor cavities with
Valve layer, the sensor cavities are interior to set the sensor processor to match with probe apparatus；The valve layer includes air inlet
Mouth, gas outlet and joystick.Existing all detection means be all gas leakage to outside, after artificial nose smells
Just handled, cause very big delay on the time, how very first time detection natural gas line gas leakage situation, this reality
With new, in order to solve this problem, first employs double-skin duct design, from the degree of guarantee for, this is further
Prevent reveal, for practical significance, this be the very first time detect gas leakage situation, double-deck natural gas line, centre is
By gap, in reset condition, i.e., when in the state of not revealing, the gas in pipeline is free from hydrogen sulfide, so this reality
With new, one layer of the increase first on the basis of conventional monolayers pipeline, middle gap layer position is reserved, middle clearance layer is set
Probe apparatus, probe apparatus can use minimum portable probe apparatus, detect hydrogen sulfide, once it is detected with hydrogen sulfide
When, the sensor processor to valve is sent by wireless base station apparatus, when receiving hydrogen sulfide information, starts warning device
Alert process, warning device here are freely set, and the utility model designs sensor processor on valve, and be is exactly
The processing of a sealing is done, avoids artificial neglectful destruction, and the unified inspection that such position is convenient when overhauling each time
Survey.The main functionality of valve is constant, still passes through joystick controlled valve.
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.
The utility model compared with prior art, has the following advantages and advantages：
1st, a kind of concentration detection apparatus of gas of the utility model, double-skin duct design is employed, from the degree of guarantee
For, this is further to prevent from revealing, and for practical significance, this is to detect gas leakage situation in the very first time；
2nd, a kind of concentration detection apparatus of gas of the utility model, avoids probe positions from not fixing, and carries and causes to damage in way
It is bad；
3rd, a kind of concentration detection apparatus of gas of the utility model, display screen is set more to be apparent from leakage
Seriousness, first intuitively sees hydrogen sulfide data, obtains the size of amount of leakage, second, intuitively see the position of accident pipeline
Put, facilitate narration situation.
