Abstract

The utility model relates to a double display double color plate type level meter. The utility model is a plate type level meter which can make full use of the interior illumination or the extraneous light to sharply display the double color, when the illuminating source is opened or closed. The utility model comprises the front and back glass plates, a cavity which is composed of the metal connecting plate, and a light emitting source, wherein, the glass plate for observation is a glass plate with angel groove, and the lateral of the glass plate is coated with the colored paint with reflecting function. The front side and two laterals of the glass plate for filtering are coated with the colored heatproof coating material, and one lateral of the glass plate is provided with a light emitting source and an illuminator. The gas-water surface of the utility model shows double color. When the inward illuminating source is opened, the gas green-water red or gas red-water green is shown. When the inward illuminating source is closed, the gas white-water black is shown. Thus, the utility model can show the optimum observation effect under different environments. The utility model has compact and simple structure, convenient dismounting, economy application and easy popularization.

Description

Two apparent double-colored board-like liquid level gauges

Technical field:

The utility model relates to a kind of double-colored board-like liquid level gauge.

Background technology:

Existing double-colored board-like liquid level gauge, be to scribble encrimson or establish the original groove glass plate of vertical an angle of 90 degrees of red optical filter and cavity that another multiple-grooved flat glass plate and housing constitute with both sides, when being water and vapour in the cavity, liquid level gauge is vapour, and red-water true qualities (transparent) show.Because the oxidation and the iron rust of iron come off in boiler, the container, make the water quality in boiler, the container become brownish red, cause vapour red-red-water brownish red that water true qualities (transparent) liquid level gauge mistake is shown as vapour, water and vapour Show Color contrast are very little, the interface two-color effect is not obvious, and especially in dim light, almost difference is not come out, can cause misjudgment, accidents caused easily.

Summary of the invention:

The purpose of this utility model is intended to overcome above-mentioned shortcoming, provides a kind of steam interface clear, and no matter the light power can both significantly show double-colored board-like liquid level gauge.

In order to achieve the above object, the utility model adopts following solution:

This pair of apparent double colored indicator comprises by bolted two housings that metal splint forms, it in the housing cavity that constitutes by two glass plates in front and back and metal through plate, it is characterized in that: as the glass plate of observation usefulness is big of an original groove glass plate that an angle of 90 degrees groove arranged or chamfered groove and inspection surface is 45 oblique single groove glass plates of spending angles, and the side of glass plate is coated with the coloured printing opacity heat-resistant coating with reflection function; Two sides as the glass plate of optical filtering usefulness scribble coloured printing opacity heat-resistant coating, and the front is coated with silvery white reflective heat-resistant coating or reflective mirror is set; A parallel sided of glass plate a light emitting source and reflective mirror be set.

Compared with prior art, the utlity model has following advantage: because the utility model is used to observe with glass plate and scribbles the coloured heat-resistant coating with reflection function, when closing inner light source, it is abundant extraneous ray of reflecting also, make the vapour-water termination of water level gauge clearly show vapour white-water is black; When opening inner light source, the vapour-water termination of water level gauge clearly show vapour green-bright pink, therefore opening or closing inner light source, can both clearly show double-colored, so claim two apparent double-colored.So water level gauge under different environment, can both show best observation effect, and it is simple and compact for structure, easy accessibility, economic and practical, be easy to promote.
