Abstract
The utility model discloses a fire extinguisher pressure indicator, which comprises a base (2), a surface mirror (7)arranged on the top of the base, a multi-loop spring pipe arranged in the base, an index dial (4), a guide gas hole (1) arranged at the center of the bottom of the base, and a gas filter arranged in the guide gas hole inlet. The utility model is characterized in that the multi-loop spring pipe is inserted into the guide gas hole through the curving elbow of the head of an inner loop; the weld point of the index dial is freely connected with the outer end of the multi-loop spring pipe, and is put on the round surface of the multi-loop spring pipe. An index indication disc(5) is adhered to the index dial; the index sign is arranged on the index indication disc; a cirque scale scutcheon (6) arranged in the base is arranged flat wise on a ladder surface of the top of the base, forming indication relation with the index indication disc. The utility model is simple in structure and reliable in performance, large on index sign with evident press indication.
Description
[technical field]
The utility model relates to a kind of pressure indicator that uses on pressurized container, particularly be a kind of pressure-indication means of fire extinguisher.
[background technique]
Be used to show the pressure indicator of the gas pressure size in the fire extinguisher, normally used pressure indicator divides spring-tube type and diaphragm type by its internal structure, and the indication of diaphragm type pressure indicator is obvious, good stability, but complex structure, cost height.The spring-tube type pressure indicator is then simple in structure, but reliability and stability are poor, and the short range of deflection of pointer is little.Existing spring-tube type pressure indicator, it includes base, bourdon tube and pointer, is placed on the base behind the bourdon tube coiled circle, and its pointer directly is connected the outer ring free end of bourdon tube.The bourdon tube pressure indicator of this structure, because pointer directly is connected the outer ring of bourdon tube, thereby its pointer is very short, range of deflection is very little, and makes indication not obvious, does not also meet new NBS.
[summary of the invention]
In order to overcome the existing existing deficiency of pressure indicator, the technical problems to be solved in the utility model provides indicates tangible a kind of fire extinguisher pressure indicator to pressure.
In order to solve the problems of the technologies described above, the utility model is finished by the following technical solutions: a kind of fire extinguisher pressure indicator, comprise base, the table mirror, be provided with the multi-turn bourdon tube in the base, the pointer rotating disk, the base bottom centre position is provided with a gas port, gas port inlet is provided with pneumatic filter, described table mirror is installed in the top of base, it is characterized in that: described multi-turn bourdon tube is inserted in the gas port by the turning of inner ring termination portion bending, the soldering point of pointer rotating disk is connected with the outer ring free end of multi-turn bourdon tube, and be placed on the disk of multi-turn bourdon tube, on the pointer rotating disk, be stained with the pointer indicator panel, on the pointer indicator panel, be provided with pointer mark, in base, be provided with circular ring type scale label, this circular ring type scale label horizontal constitutes indexical relation with the pointer indicator panel on the ladder surface of base upper end; Described turning is perpendicular to the disk at multi-turn bourdon tube place.
In the utility model, employing has the pointer indicator panel of pointer mark, replaced pointer of the prior art, thereby it is short and small to have solved pointer, and the pressure indication is not obvious, because the pointer mark on the pointer indicator panel is a kind of pattern identification, become the indicator panel of rotation plate type, objectively design its body greatly easily,, can not cause indication not obvious owing to pointer is short and small so can clear and definite indication be arranged to the pressure size.Thereby meet the requirement of GB4351-2005 standard; With the disk of turning perpendicular to multi-turn bourdon tube place, the gas pressure in the container can be delivered on the multi-turn bourdon tube effectively, make its pressure indication more accurate.
[description of drawings]
Further specify the utility model implementation detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model cut-away view;
Fig. 2 is the plan view of Fig. 1 for the utility model.
[embodiment]
As shown in Figure 1 and Figure 2, this fire extinguisher pressure indicator, comprise base 2, table mirror 7, multi-turn bourdon tube 3, pointer rotating disk 4, pneumatic filter 10, the bottom centre position of described base 2 is provided with a gas port 1,1 inlet establishes pneumatic filter 10 at gas port, and this pneumatic filter 10 is the copper filter; Described multi-turn bourdon tube 3 is formed by a few spring flat tube coilings, its inner ring termination curve disk with multi-turn bourdon tube 3 vertical turning 9, this turning 9 is inserted in the gas port 1 and with scolder 8 welding and fixes, described pointer rotating disk 4 is ring, its soldering point is welded on the outer ring free end of multi-turn bourdon tube 3, and lies on the disk of multi-turn bourdon tube 3; On this pointer rotating disk 4, be stained with pointer indicator panel 5 with glue, pointer indicator panel 5 is provided with pointer mark 11, this sign 11 can be with black or yellow stroke thereon, saved the cost of making pointer in the prior art, described circular ring type scale label 6 horizontal are on base 2 set ladder surfaces, and stick by glue, constitute indexical relations with pointer indicator panel 5.Table mirror 7 is installed in base 2 tops.The working principle of this pressure indicator is: after the gas in the pressurized container filters by copper filter 10, enter multi-turn bourdon tube 3, multi-turn bourdon tube 3 is subjected to the gas pressure resiliently deformable, drive lies in pointer rotating disk 4 rotations on multi-turn bourdon tube 3 planes, stick to the pointer indicator panel 5 on the pointer rotating disk 4 and identify 11 rotations synchronously thereby drive, to reach the purpose of indicated pressure.
Claims (2)
1, a kind of fire extinguisher pressure indicator, comprise base (2), table mirror (7), be provided with multi-turn bourdon tube (3) in the base (2), pointer rotating disk (4), base (2) bottom centre position is provided with a gas port (1), gas port (1) inlet is provided with pneumatic filter (10), described table mirror (7) is installed in the top of base (2), it is characterized in that: described multi-turn bourdon tube (3) is inserted in the gas port (1) by the turning (9) of inner ring termination portion bending, the soldering point of pointer rotating disk (4) is connected with the outer ring free end of multi-turn bourdon tube (3), and be placed on the disk of multi-turn bourdon tube (3), on pointer rotating disk (4), be stained with pointer indicator panel (5), on pointer indicator panel (5), be provided with pointer mark (11), in base, be provided with circular ring type scale label (6), this circular ring type scale label (6) horizontal constitutes indexical relation with pointer indicator panel (5) on the ladder surface of base upper end.
