Abstract
The invention discloses a kind of gas pressure calibrating installations of coal seam simulated environment, it is characterised in that: is mainly made of high pressure gas gas, pressure transmitter, calibrating room and pressure testing machine.It is mainly used for the calibrating of gas pressure detecting instrument.
Description
Technical field
The present invention relates to a kind of gas pressure calibrating installation of coal seam simulated environment, especially a kind of novel gas pressure inspection
Survey the Calibration Technology of instrument.
Background technique
Gas pressure detecting instrument is a kind of mine safety instrument, mainly for detection of the gas pressure in coal bed drilling
Power.The gas pressure that the calibrating installation of gas pressure generally uses pressure generator to generate at present is directly inputted to gas pressure inspection
It surveys in the probe of instrument, has different with the detection environment of practical coal-bed gas pressure, verification result can generate certain mistake
Difference is unfavorable for the reliable calibrating of gas pressure detecting instrument.
Summary of the invention
In order to solve the problems, such as the calibrating of gas pressure detecting instrument, the invention proposes a kind of gas of coal seam simulated environment
Pressure calibration device easily can carry out periodic verification calibration to gas pressure detecting instrument, it is ensured that this instrument detection
The reliability of data.
Used technical solution is the present invention to solve above-mentioned technical problem:
A kind of gas pressure calibrating installation of coal seam simulated environment, it is characterised in that: mainly by high pressure gas gas, pressure
Transmitter, calibrating room and pressure testing machine are constituted.It is mainly used for the calibrating of gas pressure detecting instrument.High pressure gas gas passes through
Pressure transmitter is passed through calibrating room, and pressure testing machine direct weighting gives calibrating room.
The calibrating room is made of sealing room, pressurizing piston and calibrating sample stage, wherein sealing is indoor when in use
Full of coal grain；Pressurizing piston is directly contacted with pressure testing machine, can be pressurizeed to indoor coal grain is sealed；Examining and determine sample stage is one
With externally threaded metal cylinder, tested gas pressure probe can be sent into closed calibrating room from the bottom of calibrating room
In.
The beneficial effects of the present invention are:
Periodic verification calibration easily can be carried out to gas pressure detecting instrument, it is ensured that this instrument detection data
Reliability.
