Abstract
The utility model discloses a spring tube pressure gauge with an upper limit pointer. The pressure gauge comprises a pressure gauge shell, pressure gauge scale division scribing lines, a pressure gauge pointer, a pressure gauge circle glass panel and a pressure gauge upper limit pointer. The pressure gauge upper limit pointer is fixed with the pressure gauge shell. An indication portion of the pressure gauge upper limit pointer is located on an external surface of the pressure gauge circle glass panel and a center line is parallel to the pressure gauge scale division scribing lines. The pressure gauge possesses the characteristics that the structure is simple; manufacturing is convenient; the pressure gauge is safe and reliable and so on.
Description
Technical field
The utility model relates to a kind of bourdon gauges with upper limit pointer.
Background technology
According to the fixed safe technology of pressure vessel Supervision Code of the TSG R0004-2009 of People's Republic of China (PRC) 8.4.2, stipulate: tensimeter should carry out verification before installing, and on index dial, should draw the red line of indication maximum working pressure (MOP).Tensimeter in actual the use, most of tensimeter dial plate does not carry the red pin of indication maximum working pressure (MOP), so it is on glass that the painting of the red line of indicating equipment maximum working pressure (MOP) is drawn in to dial plate, some dial plate glass rotates because of the equipment vibrations, cause the indication maximum working pressure (MOP) to indicate error, make operating personnel produce false judgment, very easily cause potential safety hazard.If the tensimeter dismounting identifies, the inner structure of meeting breaking pressure table, after impact, change tensimeter maximum working pressure (MOP) indicates.Change satisfactory tensimeter expense high.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of bourdon gauges with upper limit pointer, and it has the characteristics such as simple in structure, easy to make, safe and reliable.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Comprise pressure gauge housing, tensimeter calibration groove, gauge hand and tensimeter circular glass panel, it also comprises tensimeter upper limit pointer, tensimeter upper limit pointer and pressure gauge housing are fixed, tensimeter upper limit pointer indicating section is positioned at tensimeter circular glass panel outer surface, and its center line parallels with tensimeter calibration groove.
The utility model further improves and is:
The material of tensimeter upper limit pointer is copper, and surface is provided with the coat of paint.
The coat of paint that tensimeter upper limit pointer surface is provided with is the red coat of paint.
Tensimeter upper limit pointer is " L " shape, fixes by larynx hoop cassette tape and pressure gauge housing.
The beneficial effect that adopts technique scheme to produce is:
Because tensimeter upper limit pointer and pressure gauge housing are fixed,, tensimeter upper limit pointer sticks on tensimeter circular glass panel and compares, avoid tensimeter to drive face glass because of vibrations and pointer rotates the maximum working pressure (MOP) index error caused, avoided potential safety hazard.Tensimeter upper limit pointer indicating section is positioned at tensimeter circular glass panel outer surface, and its center line parallels with tensimeter calibration groove.Tensimeter upper limit pointer indicating section and gauge hand mutually noninterfere, and overlap when gauge hand and tensimeter upper limit pointer are in identical graduation, the accuracy of its indication ensured; Tensimeter upper limit pointer surface is provided with the red coat of paint, and redness means to warn color at production field, and eye-catching because of color, the convenient operation personnel observe; Tensimeter upper limit pointer is " L " shape, fixes by larynx hoop cassette tape and pressure gauge housing.Fixed form is simple and reliable, and facilitates tensimeter upper limit pointer resetting index.It has the characteristics such as simple in structure, easy to make, safe and reliable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the accompanying drawings: 1, pressure gauge housing; 2, gauge hand; 3, tensimeter circular glass panel; 4, larynx hoop cassette tape; 5, tensimeter upper limit pointer; 6, tensimeter calibration groove.
Embodiment
As can be known by embodiment shown in Figure 1, it comprises pressure gauge housing 1, tensimeter calibration groove 6, gauge hand 2 and tensimeter circular glass panel 3, it also comprises tensimeter upper limit pointer 5, tensimeter upper limit pointer 5 is fixing with pressure gauge housing 1, avoided tensimeter to drive face glass because of vibrations and pointer rotates the maximum working pressure (MOP) index error caused, tensimeter upper limit pointer 5 indicating sections are positioned at tensimeter circular glass panel 3 outside surfaces, and its center line parallels with tensimeter calibration groove 6.Tensimeter upper limit pointer indicating section and gauge hand mutually noninterfere, and overlap when gauge hand and tensimeter upper limit pointer are in identical graduation, ensured the accuracy of its indication,
The material of tensimeter upper limit pointer 5 is copper, and surface is provided with the red coat of paint.Redness means to warn color at production field, and eye-catching because of color, the convenient operation personnel observe.
Tensimeter upper limit pointer 5 is " L " shape, fixing with pressure gauge housing 1 by larynx hoop cassette tape 4.Can facilitate as required and adjust high workload indicated pressure.
Using method:
According to the desired maximum working pressure (MOP) of operating parameter, " L " shape tensimeter upper limit pointer is fixed by larynx hoop cassette tape and pressure gauge housing, making tensimeter upper limit pointer indicating section point to the corresponding scale of maximum working pressure (MOP) gets final product, when the desired maximum working pressure (MOP) of operating parameter changes, unclamp larynx hoop cassette tape and readjust tensimeter upper limit pointer position, by larynx hoop cassette tape, tensimeter upper limit pointer banding is got final product afterwards.
