Abstract

The utility model relates to measuring instruments and particularly to a Bourdon-tube pressure gauge. The pressure gauge comprises a gauge shell, a dial, and a glass cover arranged on the gauge shell. A holding cavity is formed between the glass cover and the gauge shell, and the dial is disposed in the holding cavity. A gauge core is arranged in a cavity formed between the dial and the gauge shell, and is connected to one end of a Bourdon tube, the other end of which is connected to a gauge joint via a flexible pipe. A hand is disposed on the gauge core above the dial. According to the above technical scheme, compared to the prior art, the pressure gauge is advantaged in that as the gauge joint is connected to the Bourdon tube via the flexible pipe, even when the gauge joint is under a force, thanks to buffering by the flexible pipe, the Bourdon tube does not move, so that precision of pressure measurement is ensured.

Description

Spring-tube type gaging pressure table
Technical field
The utility model relates to measurement instrument technical field, particularly relates to a kind of spring-tube type gaging pressure table.
Background technology
While carrying out the conveying of liquid or gas in pipeline, need to be in pipeline setting pressure instrument, be used for monitoring at any time the pressure of pipeline medium.Existing manometer can be divided into two large classes substantially: a class is digital manometer, and a class is traditional mechanical compression instrument; Digital instrument needs external power supply to work, and is not suitable for being used in pipeline and carries; Traditional mechanical compression instrument is Passive Shape Control device, without external power supply, gets final product work, has cheap, convenient for installation and maintenance advantage.But between the bourdon tube of existing mechanical compression instrument and instrument connector, be to be all connected by web member, this is connected to hard connection, when instrument connector is stressed, connected web member also can stressed movement, thereby drive bourdon tube to move, cause measuring accuracy to reduce, affect measurement effect.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of measuring accuracy high, the spring-tube type gaging pressure table that measurement effect is good.
A kind of spring-tube type gaging pressure table of the present utility model, comprise watchcase, index dial and cloche, described cloche is arranged on watchcase, and and watchcase between form an accommodating cavity, described index dial is arranged in this accommodating cavity, in the cavity forming between index dial and watchcase, be provided with meter movement, meter movement is connected with one end of bourdon tube, and the other end of bourdon tube is connected with instrument connector by flexible pipe.
On described meter movement, be also provided with indicator, indicator is arranged at the top of index dial.
As shown from the above technical solution, compared with prior art, the beneficial effects of the utility model are: when instrument connector is stressed, because this instrument connector is connected with bourdon tube by flexible pipe, even if instrument connector is stressed, through flexible pipe buffering, can not make bourdon tube be subjected to displacement, guarantee the precision of gaging pressure.The utility model carries out pressure survey applicable to non-corrosiveness matter transportation pipelines such as water, oil, gas.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model.
Embodiment
As shown in Figure 1, spring-tube type gaging pressure table of the present utility model, comprise watchcase 1, index dial 2 and cloche 3, described cloche 3 is arranged on watchcase 1, and and watchcase 1 between form an accommodating cavity, described index dial 2 is arranged in this accommodating cavity, in the cavity forming, is provided with meter movement 4 between index dial 2 and watchcase 1, meter movement 4 is connected with one end of bourdon tube 5, and the other end of bourdon tube 5 is connected with instrument connector 7 by flexible pipe 6.On described meter movement 4, be also provided with indicator 8, indicator 8 is arranged at the top of index dial 2.Instrument connector 7 is connected on the conveyance conduit of pressure, and pressure is by medium transfer to bourdon tube 5, and the free end of bourdon tube 5 produces displacement, and the angular displacement by meter movement 4 iodine, to dial plate, reach the object that shows pressure.
In use, when instrument connector 7 is accepted, because this instrument connector 7 is connected with bourdon tube 5 by flexible pipe 6, even if instrument connector 7 is stressed, through flexible pipe 6 bufferings, can not make bourdon tube 5 be subjected to displacement, finally guarantee the accuracy of the scale of indicator indication.The utility model carries out pressure survey applicable to non-corrosiveness matter transportation pipelines such as water, oil, gas.
Comprise the above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.

Claims (2)

1. a spring-tube type gaging pressure table, comprise watchcase, index dial and cloche, it is characterized in that, described cloche is arranged on watchcase, and and watchcase between form an accommodating cavity, described index dial is arranged in this accommodating cavity, in the cavity forming, is provided with meter movement between index dial and watchcase, meter movement is connected with one end of bourdon tube, and the other end of bourdon tube is connected with instrument connector by flexible pipe.
2. spring-tube type gaging pressure table as claimed in claim 1, is characterized in that, is also provided with indicator on described meter movement, and indicator is arranged at the top of index dial.
