Description
Technical field
It the utility model is related to a kind of pressure checking device, and in particular to pipe natural gas pressure checking device.
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.
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
Can not learn, all be often that situation can just be learnt when serious, thus how the very first time detection natural gas line rupture feelings
Condition, into the problem of a great research.
Utility model content
Technical problem to be solved in the utility model is that the pressure that each pipeline is born is fixed, but in reality
During border operates, because all pipelines are not that very each piece of molecular formula is all identical, send very much easily coarse in processing
Place cause to reveal, but the length of pipeline is imponderable, without so much each segment pipe arrangement of manpower and materials
Staff goes to keep, and causes Pipeline damage can not learn, and it is an object of the present invention to provide pipe natural gas pressure checking device, is solved initial stage
The pressure that each pipeline is born is fixed, but during practical operation, because all pipelines are not hundred
Divide hundred each pieces of molecular formula all identical, send very much and easily cause to reveal in the coarse place of processing, but the length of pipeline is to estimate
Meter, go to keep without so much each segment pipe personnel of arranging work of manpower and materials, cause Pipeline damage can not learn initial stage
The problem of.
The utility model is achieved through the following technical solutions：
Pipe natural gas pressure checking device, including pipeline, the pipeline is double-skin duct, between inner tubal wall and outer tube wall
Including clearance layer, in addition to the pressure sensor being arranged on pipeline；The pressure sensor includes processor and feeler；It is described
Feeler is located inside clearance layer, and the processor connection feeler is seamlessly connected with outer tube wall.The pressure that each pipeline is born
It is fixed, but during practical operation, because all pipelines are 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 is imponderable, without so much manpower thing
The each segment pipe personnel of arranging work of power go to keep, and cause Pipeline damage can not learn initial stage, and the utility model is in order to solve this
Problem, using double-skin duct, the piping failure situation of interior conduit or Outer Tube can be sufficiently detected, because either
The damage of inside and outside pipeline, the air pressure variations of inside can be all caused, internally air layer is clearance layer internally, by touching
Angle detects, and can handle by processor and show after feeler detection, and described processor shell carry display screen, and showing ought
Preceding pressure changing.Staff can learn change when inspection, be handled.
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 pressure sensor includes electric supply installation, and the electric supply installation is battery, and the processor is on the outside of outer tube wall
Face sets battery chamber.Further, as preferred scheme of the present utility model.
