Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
fig. 1 is a schematic structural diagram of a preferred embodiment of the calibration apparatus of the barometer of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a calibration apparatus for a barometer, including: a second pipeline 3 for connecting inlet 1, be used for connecting inlet, set up in first pipeline terminal first gas outlet 4 and set up in second pipeline terminal second gas outlet 5, first ball valve 6 has set gradually along the air current advancing direction on first pipeline, atmospheric pressure adjusting device 7 and standard high-pressure gauge 8, specifically, atmospheric pressure adjusting device adopts the atmospheric pressure governing valve to finely tune the size of atmospheric pressure in the pipeline, can detect the precision of treating the high-pressure gauge, second ball valve 9 has set gradually along the air current advancing direction on the second pipeline, pressure reducer 10 and standard low-pressure gauge 11, specifically, the pressure reducer is oxygen pressure reducer or nitrogen gas pressure reducer, the high-pressure gauge 12 that awaits measuring is connected to first gas outlet, the low-pressure gauge 13 that awaits measuring is connected to the second gas outlet.
