Description

A kind of pressure indicator

[technical field]

The utility model relates to a kind of tensimeter, be used for the pressure indication of various pressure vessels, be specially adapted to the pressure indication of flame snuffer.

[background technology]

At present, the pressure-indication means that is used for pressure vessel is more, and its structure is various.Habitual at present flame snuffer tensimeter, its structure all includes table body, watch glasses, be provided with multi-turn bourdon tube, pointer and dial plate in the described table body, bottom at the table body has the center pit that gas imports, be provided with filtrator in the described center pit, described multi-turn bourdon tube is arranged on the center in the table body, and the multi-turn bourdon tube has a free end, the afterbody of its pointer directly is connected with the free end of multi-turn bourdon tube, and the line segment that the end of pointer is connected with afterbody is not crossing with the longitudinal center line of table body.Like this, the length of its pointer is just very short, and the deflection amplitude of pointer is less, causes its pointing accuracy not high, does not also meet the flame snuffer national standard simultaneously.

[summary of the invention]

, needle deflection amplitude less deficiency short in view of its pointer length of flame snuffer of the prior art, the technical problems to be solved in the utility model provides a kind of pressure indicator that a kind of pointer length is long, deflection amplitude is big.

In order to solve the problems of the technologies described above, the utility model takes following technical scheme to realize: a kind of pressure indicator, include the table body, watch glasses, be provided with the multi-turn bourdon tube in the described table body, pointer and dial plate, bottom at the table body has the center pit that gas imports, be provided with filtrator in the described center pit, described pointer has end and afterbody, described multi-turn bourdon tube is arranged on the center in the table body, and the multi-turn bourdon tube has a free end, the afterbody that it is characterized in that described pointer links to each other with the free end of multi-turn bourdon tube, the line segment that is connected of described pointer afterbody and end intersects with the central axis of showing body, drives pointer running indication by the air pressure change in the multi-turn bourdon tube.

Described pointer can be installed in the below of multi-turn bourdon tube.

The afterbody of described pointer can be an annulus, and described annulus links to each other with the free end of multi-turn bourdon tube.

Described pointer can also be arranged on the scraps of paper, and the described scraps of paper are pasted the back with an annulus rotating disk and linked to each other with the free end of multi-turn bourdon tube.

The utility model links to each other the afterbody of described pointer with the free end of multi-turn bourdon tube, after the central axis that is connected line segment and table body of described pointer afterbody and end intersects, that is to say that pointer is carried out " antiposition " to be installed, make that the length of pointer is elongated, it is big that its deflection amplitude becomes, the pointing accuracy of the reservoir pressure that improves so, and meet country about flame snuffer national standard commonly used.

[embodiment]

Further embodiment of the present utility model is described in conjunction with the accompanying drawings more below.

Embodiment one, as Fig. 1, shown in Figure 2, this a kind of pressure indicator, include table body 3, watch glasses 7, be provided with multi-turn bourdon tube 8 in the described table body 3, pointer 6 and dial plate 4, bottom at table body 3 has the center pit 2 that gas imports, be provided with filtrator 1 in the described center pit 2, described pointer 6 has end 9 and afterbody 5, described multi-turn bourdon tube 8 is arranged on the center in the table body 3, and multi-turn bourdon tube 8 has a free end 11, and the afterbody 5 of described pointer 6 links to each other with the free end 11 of multi-turn bourdon tube 8, the central axis that is connected line segment and table body 3 of described pointer afterbody 5 and end 9 intersects, and this installation method of pointer is called " antiposition " installation method.Described pointer 6 is installed in the below of multi-turn bourdon tube 8, and described dial plate 4 is installed in the below of pointer 6, constitutes indexical relation with pointer 6.The pointer of installing in the present embodiment is a pointer shown in Figure 7, and rotate at the center around multi-turn bourdon tube 8 when the structure of its pointer 6 afterbodys can make pointer rotate, and multi-turn bourdon tube 8 can not hinder the rotation of pointer 6.

Embodiment two, as shown in Figure 3, Figure 4, the basic structure of this embodiment is identical with embodiment one, its distinctive points is the structure difference of pointer 6, the afterbody 5 of this pointer is an annulus, as shown in Figure 8, the joining of pointer end 9 overtimes and this annulus 5 is exactly the tie point of pointer 6 and multi-turn bourdon tube free end 11, and the same central axis with table body 3 of the line segment that this tie point links to each other with pointer end 9 intersects.Present embodiment is the same with embodiment one, and this pressure indicator of directly being indicated by pointer is called pointer pressure indicator.

Embodiment three, as Fig. 5, shown in Figure 6, so the difference of this embodiment and the various embodiments described above is being drawn in pointer 6 on the scraps of paper 10, the scraps of paper 10 are sticked on the annulus rotating disk 12, annulus rotating disk 12 positions shown in the pointer afterbody 5 are connected with the free end 11 of multi-turn bourdon tube again, dial plate 4 are installed in the top of multi-turn bourdon tube 8 again, constitute indexical relation with pointer, other structure is identical with embodiment one, and the indicator of this structure is called as the rotating disc type pressure indicator.

A kind of pressure indicator of the present utility model also has multiple conversion and remodeling; be not limited to above-mentioned embodiment; mechanism as pointer; other shapes of table body etc.; in a word; every afterbody of pointer that utilizes links to each other with the free end of multi-turn bourdon tube, and the line segment that is connected of described pointer afterbody and end intersects with the central axis of showing body, and just the pointer structure of so-called " antiposition " installation all belongs within the protection domain of the present utility model.
