Abstract
The utility model discloses a gas pressure recorder especially used for measurement records for the pressure of less than 0.25Mpa. A sensing element measuring gases adopts a corrugated pipe and a spring assembly, mechanical drive adopts a connecting rod mechanism, and the recording part uses a recording pen assembly. The corrugated pipe and the spring assembly are connected with the mechanical driving mechanism which is connected with the recording part. When measuring smaller pressure, the utility model has the advantages of high measuring precision and little error.
Description
A kind of gaseous tension registering instrument, the survey record of the less pressure of particularly suitable (less than 0.25Mpa).
Existing gaseous tension instrument adopts spiral pipe or Baden's pipe to do gas sensor, and instrument range is big, and less pressure (less than 0.25Mpa) time error is bigger measuring.
The purpose of this utility model is to solve the argoshield manometer measuring the big problem of less pressure time error, and more accurate pressure value is provided.
The gaseous tension registering instrument of the utility model indication comprises flexible member, mechanical driving mechanism and recording section.Flexible member links to each other with mechanical driving mechanism, and mechanical driving mechanism is connected with recording section.The feature of this programme is that flexible member adopts corrugated tube and range spring assembly, and the stiff end of corrugated tube is fixed on the base plate by support, and its air admission hole is communicated with connecting pipe, and the free end of corrugated tube is connected with mechanical driving mechanism; Range spring assembly one end is fixed on the support of fixing corrugated tube, and the other end is connected with mechanical driving mechanism.
Above-mentioned mechanical driving mechanism comprises and draws bar, driving lever, connecting rod, adjuster bar, rotating shaft.Draw angle between bar and driving lever between 30 °～90 °.
When the pressure of measured medium enters corrugated tube through connecting pipe, under the pressure medium effect, the corrugated tube free end is rectilinear motion up and down, be fixed on corrugated tube and draw bar and driving lever also moves up and down, the drivening rod motion is rotated adjuster bar, thereby makes the rotating shaft rotation, drive is fixed on the recording section motion in the rotating shaft, and the pressure record of measured medium is got off.
This gaseous tension registering instrument adopts corrugated tube and range spring assembly to make sensitive element, because corrugated tube inner chamber lifting surface area is bigger, susceptibility is strong, is out of shape obviously under less pressure effect, so little at the less gaseous tension time error of measurement, measuring accuracy improves.And can in less than the 0.25Mpa pressure limit, form the measurement instrument of different ranges.
Embodiment: accompanying drawing is the structural representation of the utility model gaseous tension registering instrument, below in conjunction with accompanying drawing, embodiment is done explanation in more detail.
(1) is corrugated tube in the accompanying drawing, and the stiff end of corrugated tube (2) passes support (3) and support is fixed together, and support and base plate (4) are fixing, the free end of corrugated tube (5) with draw bar (6) and fixedly connected.On support, be fixed with the spring(-supported) mount (8) that rod member (7) is used for supporting the range spring assembly, be welded with several springs (9) of symmetry in the spring(-supported) mount bottom, the other end of spring (9) is fixed on garden bowl (10), and circle bowl (10) is enclosed within and draws that bar (6) is gone up and with to draw bar fastening.Drawing bar (6) other end fixedlys connected with driving lever (11), driving lever (11) other end and connecting rod (12) flexibly connect, connecting rod (12) other end and adjuster bar (13) flexibly connect, the adjuster bar other end is fixed in the rotating shaft (14), be fixed with the linear relationship that recording pointer assembly (15), nut (16), screw (17), (18) are used for adjusting registering instrument respectively in the rotating shaft (14), recording interval and adjust zero-bit.On base plate, be fixed with industrial clock (19) and be used for activation record paper (20) along with clock (19) rotates.The ink bottle (21) of supply recording pointer liquid, ink conducting tube (22) all adopts pipe clamp (23), (24) to be fixed on the base plate.
When the pressure of measured medium enters corrugated tube (1) through connecting pipe (25), under the pressure medium effect, corrugated tube free end (5) is rectilinear motion up and down, with corrugated tube free end (5) fixing draw bar (6) and driving lever (11) also moves up and down, and connecting rod (12) movement therewith of driving lever (11) flexible connection, make adjuster bar (13) rotate, drive rotating shaft (14) running, thereby make the recording pointer assembly (15) on the fixed rotating shaft (14) go up swing at recording chart (20).Recording chart is so just clearly noted the pressure of measured medium at the instantaneous value that diel changes along with industrial clock diel rotates a circle, and the registering instrument precision reaches 1.0 grades.When drawing bar (6) during rectilinear motion up and down, the free end (5) of corrugated tube (1) also moves up and down, the circle bowl (10) fixing with drawing bar also moves up and down together, spring is subjected to pressure along with moving up and down of circle bowl so, makes the range spring assembly produce stable equilibrium's effect to corrugated tube.
