The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
As shown in Figs. 1-3, the airlock special pressure recorder of the utility model embodiment, including：At least all the way
Pressure measuring system 1 and record system 2.
Specifically, including per road pressure measuring system：Connector, the pressure measurement bourdon tube 11 being connect with connector, connecting rod 12, shaft 13
With recording pen 21.Wherein, one end of connecting rod 12 is connect with pressure measurement bourdon tube 11, and the other end of connecting rod 12 connects with one end of shaft 13
It connects, the other end of shaft 13 is connected with recording pen 21, and the one end being connect with connecting rod 12 per the shaft 13 of road pressure measuring system is rotatable
Fixation together.
Record system includes being mounted at the center of recording sheet 22 from clock is counted, with predetermined period from meter clock and recording sheet 22
It rotates clockwise, (one week) forming curves is rotated by the time set.
The operation principle of airlock special pressure recorder is illustrated below：
When measured medium enters bourdon tube by connector, bourdon tube free end is made to generate position under the action of pressure medium
It moves, this displacement drives pointer and recording mechanism by pull rod, and pressure value is indicated and recorded in recording sheet 22.It is specific next
It says, pressure enters pressure measurement bourdon tube 11 by connector, and the pipe end of driving spring pipe generates displacement, and then passes through connecting rod 12 and shaft
13 realize power conduction.That is, pressure is conducted by bourdon tube to connecting rod 12, and then conducted to shaft 13, by spring by connecting rod 12
The displacement that the pipe end of pipe generates is converted into angular displacement, secondary displacement is converted to angular displacement by connecting rod 12 and shaft 13, and pass through
The recording pen 21 of 13 end of shaft draws lower curve in recording sheet 22, as pressure record curve.Due to counting certainly for record system
Clock is rotated clockwise with predetermined period, to drive recording sheet 22 to rotate.The recording pen 21 being connect with 13 end of shaft is suspended from note
The top for recording paper 22, so as under the action of conduction next pressure, lower curve be drawn in recording sheet 22, as pressure record
Curve.Power supply is done by a section C-size battery from meter clock, driving recording sheet 22 rotates in a clockwise direction, and recording pen 21 is in recording sheet
Radial indicated value on 22 is to be tested pressure value accordingly.
