Description
Technical field
The present invention relates to a kind of pressure checking device, and in particular to uses the gas pressure detection unit in residential building.
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
Add 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
The sixties in 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.China is in the peaceful interconnection pipeline engineering in Ji, first X80 levels pipe line steel for 7.71km's
Test section.A diameter of 1219mm X80 steel-grade pipe line steel is all employed up to 4843km the second west to east gas pipeline project main pipeline,
Distribution pressure is brought up into 12Mpa.In general, X80 steel is ferrite and bainite duplex structure, and X100 pipe line steels are bayesian
Body tissue, X120 pipe line steels are ULCB and martensite.For the tubing of natural gas line, intensity, toughness and
Solderability is 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.
The content of the invention
The technical problems to be solved by the invention are that the pressure that each pipeline is born is fixed, but in actual behaviour
During work, because all pipelines are not that very each piece of molecular formula is all identical, send very much and easily processing coarse ground
Fang Zaocheng is revealed, but the length of pipeline is imponderable, is arranged work without so much each segment pipe of manpower and materials
Personnel go to keep, and cause Pipeline damage can not learn initial stage, and it is an object of the present invention to provide using the gas pressure detection unit in residential building,
It is fixed to solve the pressure that each pipeline is born, but during practical operation, due to all pipelines not
It is 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 not
It is estimable, go to keep without so much each segment pipe personnel of arranging work of manpower and materials, cause Pipeline damage initial stage can not
The problem of learning.
The present invention is achieved through the following technical solutions：
Using the gas pressure detection unit in residential building, including pipeline, the pipeline is 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, and the processor connection feeler is seamlessly connected with outer tube wall.Each pipeline is born
Pressure be all fixed, but during practical operation, because all pipelines are not very each piece of molecule
Formula is all identical, send very much and easily causes to reveal processing coarse place, but the length of pipeline be it is imponderable, it is not so much
The each segment pipe personnel of arranging work of manpower and materials go to keep, cause Pipeline damage can not learn initial stage, the present invention 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 not
Pipe is the damage of inside and outside pipeline, can all cause the air pressure variations of inside, and internally air layer is clearance layer internally, is led to
Feeler is crossed to detect, can handle and show by processor after feeler detection, described processor shell carries display screen, shows
Show current pressure situation of change.Staff can learn change when inspection, be handled.
Alarm built in the pressure sensor, institute's alarm are buzzer siren.Further, as the preferred of the present invention
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, the preferred scheme as the present invention.
The pressure sensor uses DYM3 models, further, as the preferred scheme of the present invention, high sensitivity, price
It is cheap.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention, using double-skin duct, can be visited sufficiently using the gas pressure detection unit in residential building
The piping failure situation of interior conduit or Outer Tube is surveyed, because the damage of either inside and outside pipeline, can all cause the air of inside
Pressure change, internally air layer is clearance layer internally, is detected by feeler；
2nd, for the present invention using the gas pressure detection unit in residential building, processor shell carries display screen, and display is current
Pressure changing, staff can be learnt change when inspection with straight tube, be handled；
3rd, the present invention includes electric supply installation, the confession using the gas pressure detection unit in residential building, pressure sensor
Denso is set to battery, and the processor sets battery chamber in outer tube wall lateral surface.
