Abstract
The utility model relates to the products of the class of level meters, particularly a night viewing two-color level meter. The night viewing two-color level meter is composed of filter glass, a luminous body, a level meter glass tube, the dustproof glass of an observation face, etc., wherein, the luminous body is arranged at the middle position of the filter glass. The luminous body can be divided into the luminous body with a luminous source and the luminous body without a luminous source. The luminous body without the luminous source is fluorescent composite materials; the active luminous body with the luminous source is charge-excitation luminescent materials; the passive luminous body with the luminous source is composed of an electric luminous source, an optical fiber and a luminous body. The utility model has the advantage of simple structure and can work in different working environments, especially in the occasions with different pressure and temperature and inflammable and explosive occasions.
Description
The utility model relates to the liquid level instrument series products, but particularly a kind of liquid is looked double colored indicator.
At present, liquid level instrument industry at home and abroad, on-the-spot class instrument product majority can only be applicable to daytime or under light source irradiation, no flammable, just can not use the liquid level gauge of band light source in the explosion environment, for example, boiler is with band light source water level gauge.And in industries such as petrochemical industry, oil refining, chemical fibres, the liquid level gauge overwhelming majority works under inflammable, the explosive again occasion of existing pressure, temperature.Therefore, above-mentioned industry can not directly be used normal tape light source liquid level gauge, and is like this, very difficult in the night-time observation liquid level.
The utility model is exactly for addressing the deficiencies of the prior art, but and provides a kind of liquid to look double colored indicator.
The principle that the utility model adopts is based on the quartz ampoule double colored indicator optical principle that is widely used, and utilizing has no liquid, the refraction of light, and reflectivity changes, and makes colored light after the optical filtering be aspect observation that vapour is red, liquid is green, shows liquid level.The utility model is by enamel glass, luminophor, and the level gauge glass pipe, compositions such as inspection surface dustproof glass, wherein, luminophor is in the enamel glass centre position, because the displaying principle of double colored indicator, then luminophor can show that in table fluid is a height.
The utility model compared with prior art has following advantage:
1. simple in structure, manufacture easily.
2. applied widely, can be under different working environments, work under promptly different pressure, temperature, inflammable, the explosive occasion.
Describe the utility model in detail below in conjunction with accompanying drawing;
Fig. 1 is the structural representation of the utility model enamel glass, luminophor;
Fig. 2 is the utility model level gauge glass tubular construction synoptic diagram;
Fig. 3 is the utility model inspection surface dustproof glass synoptic diagram;
Fig. 4 is a kind of embodiment of the present utility model.
From Fig. 1 to Fig. 3 as can be seen: the utility model is by filter glass 1, luminophor 2, and level gauge glass pipe 3, inspection surface dustproof glass 4 compositions such as grade, wherein, luminophor 2 is installed in the centre position of filter glass 1.Luminophor had light source and no light source two classes in 2 minutes, and having in the light source class can the branch active illuminating and passive luminous two kinds.No light source luminophor is a fluorescence composite material, and instrument is manufactured simple, and safety easy to use has light source active illuminating body to be the charge drive luminescent material, and low in energy consumption, brightness is higher.Form by three parts by the passive luminophor of light source, 1. electric light source; 2. light transmitting fiber; 3. luminophor.The light that electric light source produces forms colorama by the light transmitting fiber color fluorescence material diffuse reflection in luminophor, the body of passing on a skill of craft to others, and the demonstration liquid level of using is clear and intuitive.Explosion-proof light source has the passive luminophor of light source, shows the explosion-proof light source that needs configuration good.Fig. 2 is an embodiment of the present utility model, and it is by light transmitting fiber 5, electric light source case 6, and liquid level gauge 7 is formed.Electric light source case 6 is fixed on the power lead terminal pipeline, and the light that light-emitting component produces in the electric light source case 6 imports in the luminophor of liquid level gauge 7 through light transmitting fiber 5.
Claims (5)
1. but a liquid is looked double colored indicator, by filter glass (1), and luminophor (2), level gauge glass pipe (3), inspection surface dustproof glass compositions such as (4) is characterized in that luminophor (2) is installed in the centre position of filter glass (1).
2. liquid level gauge according to claim 1 is characterized in that luminophor (2) branch has light source and no light source two classes.
3. liquid level gauge according to claim 1 is characterized in that it is the charge drive luminescent material that the active illuminating body of light source is arranged.
4. liquid level gauge according to claim 1, the passive luminophor that it is characterized in that light source is arranged be by electric light source, light transmitting fiber, and luminophor is formed.
5. liquid level gauge according to claim 1, it is characterized in that not having the light source luminophor is fluorescence composite material.
