Abstract
The utility model provides a colored fluid level gauge with a triple prism mirror. The utility model is characterized in that the colored fluid level gauge with a triple prism mirror is provided with a triple prism mirror and one or two pieces of transparent colored objects with different colors, and the transparent colored object displays in one color or two. The colored fluid level gauge with a triple prism mirror has the advantages of novel design, simple structure, low cost, high reliability, convenient maintenance and non-strong light source, so the colored fluid level gauge with a triple prism mirror is suitable for the liquid level display of the boiler and other equipment.
Description
The utility model belongs to level instruction device, and especially a kind of coloured level measurement meter that uses prism is specially adapted to boiler water level observation.
The existing coloured water level indicator of boiler, mainly by reflective mirror, light source, transparent colored glass, post loose mirror, two blocks of angled sheet glass, the post that has a mao plane looses mirror and the water-level observation container is formed, its structure is extremely complicated, simultaneously, because of big portion light has lost in the optical system of complexity, so be difficult for teletransmission; The Installation and Debugging trouble; The service condition harshness needs stronger light source and good optical system and sanitary condition.The kettleman must wash every day, wipes examination, often maintenance, and cost is very high.
The purpose of this utility model provides a kind of novel colored level measurement meter, and it is simple in structure, and cost is very cheap, uses maintenance easily, and does not need stronger light source.
Task of the present utility model is finished in such a way: light source is by transparent colored substance, inject in the liquid level observation container that has surveillance mirror, this transparent colored substance can be a coloured sheet glass, also can be arc coloured glass and coloured lamp etc., transparent colored substance can be contained on the liquid level observation container, with hydraulic seal, anti-certain pressure, also can observe outside the container in liquid level, be equipped with on the liquid level observation container transparent withstand voltage can be with the sheet glass of hydraulic seal, there is coloured light to inject in the liquid by sheet glass, or the like.Has a prism in the liquid level observation container, a plane of prism is roughly parallel with surveillance mirror, between this plane and colored substance, has another plane of the acutangulate prism of dihedral angle of and this Plane intersects.Here the surveillance mirror of saying refers generally to colourless transparent plate glass, but also can be convex lens, has amplification, or the like.At this moment, the part of water is arranged, can see the color of coloured glass.
In order to make no water section become another kind of color, can make the 3rd plane of prism roughly rectangular with first plane, relative with the 3rd plane, have transparent colored substance and light source with above-mentioned transparent colored substance different colours, light source is injected prism by this transparent colored substance.This transparent colored substance can be contained in outside the liquid level observation container, what an anti-certain pressure arranged between the 3rd plane of prism and transparent colored substance can be with the clear plate glass of hydraulic seal, also can be directly replace this sheet glass with the transparent colored glass of anti-certain pressure, etc.
Above-mentioned prism can be done with the surveillance mirror branch, is preferably made one, is convenient to fix.
The acute angle of above-mentioned prism be 45 °-60 ° better, but be preferably in 50 °-55 °.Between.
Its principle of work is: when water was arranged, prism was destroyed, and human eye can be seen the color of opposite colored substance by surveillance mirror.When anhydrous, this color has been reflected away by prism, and what see then is the colored substance on opposite, the 3rd plane reflexes to human eye by prism color.
Compared with the prior art, the utility model structure is extremely simple, and cost is very cheap, uses maintenance easily, and does not need stronger light source.
Embodiment one: the monochromatic water level indicator of boiler.
Fig. 1 is its stereographic map.
Fig. 2 is its cross section structure synoptic diagram.
See Fig. 2, by five pairs of bolts (1) with metal shell (2) and clear plate glass (3), with be fixed together with the prism (7) that is made of one of observation sheet glass, watertight is encapsulated in the observation container, light source (4) is injected in the observation container by transparent red glass (5), (6) be water, have the part of water to take on a red color, anhydrous colourless.
Embodiment two: the double-colored water level indicator of boiler.
Fig. 3 is its cross section structure synoptic diagram.
See Fig. 3, on the basis of embodiment 1, open-work (12) and clear plate glass (8) on betal can, have been increased, be fixed on the shell with screw rod (11), anti-sealing leaks, and light source (10) is injected prism by green transparent glass (9), when water is arranged, what human eye was seen is red, and anhydrous part then is green.
Claims (8)
1, a kind of coloured level measurement meter that has light source, transparent colored substance and have the liquid level observation container of surveillance mirror, it is characterized in that having a prism in the liquid level observation container, a plane of prism is roughly parallel with surveillance mirror, between this plane and colored substance, has another plane that a dihedral angle with this Plane intersects acutangulates prism.
2, coloured level measurement meter as claimed in claim 1, it is characterized in that roughly meeting at right angles with first plane with the 3rd plane of said prism, relative with the 3rd plane, have transparent colored substance and light source with above-mentioned transparent colored substance different colours, light source is injected prism by colored substance.
3, coloured level measurement meter as claimed in claim 1 or 2 is characterized in that said prism and surveillance mirror make one.
4, coloured level measurement meter as claimed in claim 1 or 2 is characterized in that said pitch-angle is 45 °-60 °.
5, coloured level measurement meter as claimed in claim 3 is characterized in that said pitch-angle is 45 °-60 °.
