Abstract

The utility model provides a multifunctional pressure gage, which relates to an instrument. The utility model comprises an isolator part, and a measuring device part. A measuring instrument is connected with a lower base by ordinary screw threads; a sealing plate for oil injection is positioned at the inner side of the base; a soft insolating sheet is pressed into a sealing groove which is positioned at the inner side of an outer casing; an air hole, which is positioned at the lower side of the utility model, is communicated with the soft insolating sheet. The utility model has the advantages that media which are measured can be isolated, shocks can be prevented, the utility model can resist high temperatures, the indicated pressure is right, the work is reliable, the service life is long, the cost is low, etc.

Description

Multifunctional pressure gage

The utility model relates to a kind of tensimeter.

Existing instrument model is more, and its complex structure, inner spacer adopt inhales steel disc, oil hole design unreasonable, so that amount is less during oiling, serviceable life is short, cost is higher, and many instrument are usually scrapped because of less nothings of store oil is oily.In order to overcome the few shortcoming of injection flow, the instrument that has adopts and connects the oiling of flexible pipe mode, trouble so, and common instrument cost is higher, and people wish to have that a kind of measurement effect is good, simple in structure, the appearance of the Multifucntional instrument of long service life.

The purpose of this utility model be design a kind of simple in structure, with low cost, have that four kinds of functions are promptly shatter-proof in one, the novel product of anti-impact, isolation measured medium, heatproof comes out.

The purpose of this utility model realizes by following scheme:

This product is made up of diaphragm isolator and measurement mechanism two parts; Measurement instrument (7) is connected with STRTHD with lower bottom base (3), oiling sealing gasket (4) is in the inboard of lower bottom base (3), soft spacer (2) is pressed in the inboard seal groove (5) of shell body (1), and the bleeder vent of downside (6) communicates with soft spacer (2).

Good effect of the present utility model is:

Characteristics such as this instrument has that cost is low, stable correct, the reliable operation of anti-impact, shatter-proof, high temperature resistant, indication, long service life.

That this instrument integrates is shatter-proof, anti-impact, isolation, heatproof, and its earthquake-proof function can exceed more than the shatter-proof table one times in the present use; High temperature resistant reaching+150 ℃, and having and the same performance of the shatter-proof table of barrier film, advantages such as cheap, the long service life that has again that the shatter-proof table of barrier film do not had.

This instrument is because anti-impact, shatter-proof and can bear the unexpected ascending, descending of stress alternation and press, so be specially adapted to measure the liquid that impurity is many, solidifying point is high, viscosity is big, the metering under the abominable working environments of department such as oil, chemical industry, electric power, mine.

Fig. 1 is a Figure of abstract of the present utility model, Figure of description.Its structure is as shown in the figure:

1 shell body, 2 soft barrier films, 3 lower bottom bases, 4 oiling sealing gaskets, 5 isolation channels, 6 bleeder vents, 7 measurement instruments.

Its annexation is:

Measurement instrument (7) is connected with STRTHD with lower bottom base (3), oiling sealing gasket (4) is in the inboard of lower bottom base (3), soft spacer (2) is pressed in the inboard isolation channel (5) of shell body (1), and the bleeder vent of downside (6) communicates with soft spacer (2).

Structural principle:

This instrument is made up of diaphragm isolator and measurement mechanism two parts, and the suitable spacer pad of chamber filling within it.

When the pressure of measured medium acts on the diaphragm, make it to produce distortion, the spacer pad of compression inner chamber conducts to the bourdon tube of measurement instrument, makes it to produce displacement and drives gauge pointer and indicate measured medium pressure.

Technical data:

1. this accuracy of instrument grade is 1.5 grades.

2. measurement range: 0-100MPa.

3. measured medium temperature :-30 ℃-+150 ℃.

4. specifications and models: Y100(150), below the 100MPa.

Claims

A kind of multi-purpose pressure meter, form by diaphragm isolator and measurement mechanism two parts, it is characterized in that measurement instrument (7) is connected with STRTHD with lower bottom base (3), oiling sealing gasket (4) is in the inboard of lower bottom base (3), soft spacer (2) is pressed in the inboard seal groove (5) of shell body (1), the bleeder vent of downside (6) communicates with soft spacer (2), and lower bottom base charges into certain amount of fluid in (3).
