Specific embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
As shown in Figs. 1-3, the airlock special pressure recorder of the embodiment of the present invention, including：At least pressure measurement all the way
System 1 and record system 2.
Specifically, include per road pressure measuring system：Connector, the pressure measurement bourdon tube 11 being connect with connector, connecting rod 12, shaft 13 and
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 per the shaft 13 of road pressure measuring system with connecting rod 12 is rotatable
Fixation together.
Record system is included from meter clock and recording sheet 22, is mounted at the center of recording sheet 22 from clock is counted, with predetermined period
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 pass through connecting rod 12 and shaft
13 realize power conduction.That is, pressure is conducted by bourdon tube to connecting rod 12, and then is conducted by connecting rod 12 to shaft 13, by spring
The displacement that the pipe end of pipe generates is converted into angular displacement, secondary displacement is converted to angular displacement, and pass through by connecting rod 12 and shaft 13
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, so as to which recording sheet 22 be driven to rotate.The recording pen 21 being connect with 13 end of shaft is suspended from note
The top of paper 22 is recorded, so as under the action of the next pressure of conduction, 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 direction indicated value on 22 is tested pressure value accordingly.
In one embodiment of the invention, the curve formed in the recording sheet 22 of record system per road pressure measuring system
The pressure changing of intersection point, as this moment of airlock.
