Description
Technical field
The utility model relates to the Measuere for fluid pressure table, the synchronous indicating gauge of particularly a kind of pressure pressure reduction.
Background technology
At present fluids such as gas, steam, liquid are carried out tonometric method, generally adopt the gauge measurement force value.This manometric principle of work is: when pressed gas (steam, liquid etc.) enters manometric pressure chamber, arrive bourdon tube again, because the pressure effect of pressed gas (steam, liquid etc.), bourdon tube expands, the pulling sector gear rotates, sector gear drives the pointer shaft gear and rotates, and pointer also and then rotates, and the force value of this equipment just can be read in the position of pointer on the scale of chassis like this.The deflection angle of pointer is directly proportional with the pressure size.
Also have the working pressure sensor to add the secondary instrument measured pressure value.The method that equipment inlet and outlet pressure difference is measured is to measure the import and export pressure data respectively with two tensimeters, carries out subtraction again, obtains pressure difference value.Also can obtain the import and export pressure signal, send into operational amplifier, demonstrate the pressure difference value of import and export again by secondary instrument with two pressure transducers.Perhaps measure, when the import and export pressure difference value of equipment reaches predetermined value, send signal, but can not read pressure difference value with the differential pressure signalling generator.
By above-mentioned and know, up to the present also only just can not show force value and pressure difference value simultaneously with an instrument.
Summary of the invention
Task of the present utility model provides the synchronous indicating gauge of a kind of improved pressure pressure reduction, and it has solved the problem that prior art can not show force value and pressure difference value simultaneously with an instrument.
The technical solution of the utility model is as follows:
The synchronous indicating gauge of a kind of pressure pressure reduction, it comprises housing, pressure cavity and pressure chamber, core frame of on pressure cavity, settling and bourdon tube, the rotating shaft that has gear of in the core frame center pit, installing, be placed in the sector gear on the core frame, the connecting rod of between sector gear and bourdon tube, installing, be installed in the pointer in the rotating shaft, and the chassis and the cover cap that have scale, described core frame, pressure chamber, bourdon tube, rotating shaft, sector gear, pointer is respectively equipped with two, be used separately as intake pressure indication and top hole pressure indication, the intake pressure rotating shaft is passed the center pit of two core frames to the scale chassis, the top hole pressure shaft set is in the intake pressure rotating shaft, and the center pit that passes core frame is to the scale chassis, and intake pressure rotating shaft axle head is equipped with the intake pressure pointer, and top hole pressure rotating shaft axle head is equipped with the top hole pressure disk pointer of band scale.
The synchronous indicating gauge of pressure pressure reduction of the present utility model can be at the pressure difference value between two force value of import and export that indicate equipment on the surface simultaneously and the import and export, and three data can directly be read, and do not require calculation.The utility model is assembled into one with two manometric movements, the pointer that indicates mouth pressure is designed to a disk pointer that has same pressure scale, " 0 " place value place of circular dial scale is provided with the needle-like pointer, and it is that position on the big dial plate indicates the mouth pressure value on the scale chassis.The intake pressure value is indicated in intake pressure pointer to the position on the big dial plate, the pressure difference value of the position indication import and export on the disk pointer scale.A table of the present utility model has the function of three tables, has reduced the expense of purchasing instrument thus, has saved the installation site.Direct reading during use has been saved the time, has reduced mistake.

Fig. 2 is the synoptic diagram that the pointer of the watch face of Fig. 1 indicating gauge is designated as virgin state.
Fig. 3 is the synoptic diagram that the pointer of the watch face of Fig. 1 indicating gauge is designated as duty.
Embodiment
Referring to Fig. 1, the synchronous indicating gauge of a kind of pressure pressure reduction of the present utility model is equipped with housing 1, pressure cavity 2, first pressure chamber 3 and second pressure chamber 4, on pressure cavity 2, settle first core frame 5 and second core frame 6 and first bourdon tube 7 and second bourdon tube 8, installing has the rotating shaft of gear in core frame 5,6 center pits, on core frame 5,6, settle first sector gear 9 and second sector gear 10 respectively, installing connecting rods between sector gear and bourdon tube is at the graduated chassis 11 of the front end mounting strap of housing 1, cloche 12 and Biao Gai 13.
Core frame of the present utility model, pressure chamber, bourdon tube, rotating shaft, sector gear, pointer are respectively equipped with two, as mentioned above, are the first and second, are used separately as intake pressure indication and top hole pressure indication.
Intake pressure rotating shaft 14 is passed the center pit of two core frames 5,6 to scale chassis 11, top hole pressure rotating shaft 15 is set in the intake pressure rotating shaft 14, and the center pit that passes second core frame 6 can relatively rotate between intake pressure rotating shaft 14 and the top hole pressure rotating shaft 15 to scale chassis 11.Intake pressure rotating shaft 14 axle heads are equipped with intake pressure pointer 16, and top hole pressure rotating shaft 15 axle heads are equipped with the top hole pressure disk pointer 17 of band scale.
Referring to Fig. 2 and Fig. 3, " 0 " place value place of the circular dial scale of top hole pressure disk pointer 17 is provided with the needle-like pointer.
The utility model in use, with the outlet 18 of the second pressure chamber connection device on second core frame, with the import 19 of the first pressure chamber connection device on first core frame.When fluid flows through equipment, because of the device for flow body has resistance, form pressure differential at import and export two ends, intake pressure is greater than top hole pressure.As shown in Figure 3, at this moment, angle α of top hole pressure disk needle deflection, according to top hole pressure disk pointer is position on the big dial scale on the scale chassis, from big dial scale, can read a force value (for example 0.4MPa), be the top hole pressure value, pressure scale " 0 " position on the top hole pressure disk pointer also forwards the 0.4MPa position to simultaneously.The intake pressure pointer is angle β of deflection also, according to the position of intake pressure pointer on big dial scale, reads a force value (for example 0.45MPa) from big dial scale, is the intake pressure value.Because intake pressure is greater than top hole pressure, so the deflection angle β of intake pressure pointer is greater than the angle of deflection of top hole pressure disk pointer, this moment, the intake pressure pointer formed a deflection angle with respect to top hole pressure disk pointer (" 0 " position of disk pointer high scale), can read force value (as 0.05MPa) according to intake pressure pointer to the position on the scale of top hole pressure disk pointer, this value is exactly a pressure difference value, has saved calculation step.
