Abstract
The utility model discloses a reflecting single or double colors fluid level gage with two direction light sources with long service life and clear liquid level display, which is composed of a glass plate, a gage body, a light source lamp, a reflecting plate and a fastening device. The center of the glass plate is provided with a right groove, and the entire contacting surface which is connected with the fluid is painted with or affixed with a high-temperature resistant, high pressure resistant, anti-gas-corrosion, anti-fluid-corrosion protective layer, with a light source illuminated or the reflecting plate with high reflectivity, which makes the fluid level gage able to clearly display the liquid level. The color contrast is clear, and the utility model can be used for monitoring the liquid level in a remote distance.
Description
The invention belongs to the improvement of liquid level gauging technology.
Existing reflective single, double look liquid level gauge generally is to utilize natural lighting, or throws light on a front illuminator.Because it is by reflection ray that liquid level shows, and the loss of strength of light reflex time is many, therefore, it is clear inadequately bright that liquid level shows, can not be from the remote monitoring liquid level.In addition, existing reflective double colored indicator glass plate directly contacts with liquid, the gas of High Temperature High Pressure, the clear 58-7299 of Jap.P. for example, though on the male and female face of glass plate, scribble coating, be the branch that color is arranged when showing, glass pane surface is not corroded, transmitance descends gradually after being corroded, have a strong impact on the sharpness of liquid level, so serviceable life is very short, will changes once in about 1 year.
The purpose of this invention is to provide a kind of follow-on reflective single, double look liquid level gauge, its shown liquid level is clear, bright, and color contrast is obvious, can be in the remote monitoring liquid level.The glass plate of this liquid level gauge can be high temperature resistant, high pressure and gas and liquid corrosion, can keep good transmittance for a long time.

Accompanying drawing 7 is the reflective double-colored liquid level meters of two-way illumination, in the closed cavity that right angle groove (2) forms with table body (10) driving fit, and structure cut-open view and index path when being full of gas.Sequence number 1～10 is ditto described among the figure, and 11 is the enamel reflector, and 12 are the colour filter coating, and 13 is cylinder condenser lens, and 14 is the front illuminator.
Accompanying drawing 8 is the reflective double colored indicators of two-way illumination, in the closed cavity that right angle groove (2) forms with table body (10) driving fit, and structure cut-open view and index path during full of liquid, sequence number 1～14 is all ditto described among the figure.
After accompanying drawing 9 is the illuminator (6) of the reflective double colored indicator of two-way illumination both sides and reflector (15) that reflection shield (7) replaces high reflectance, in the closed chamber that right angle groove (2) forms with table body (10) driving fit, be full of the structure cut-open view and the index path of gas.1～14 is ditto described among the figure, and 15 is reflector, and 16 is reflector layer.
Accompanying drawing 10 is after reflective double colored indicator two side illuminant lights of two-way illumination (6) and reflection shield (7) replace the reflector (15) of high reflectance, in the closed chamber that right angle groove (2) forms with table body (10) driving fit, the structure cut-open view and the index path of full of liquid.1～16 is all ditto described among the figure.
Main points of the present invention: the reflective monochromatic liquid level gauge of two-way illumination is that illuminator (6) and reflection shield (7) are housed in the both sides of glass plate (18), and is coated with or is stained with color filter (4) and light shield layer (5) in the glass plate both sides; The reflective double colored indicator of two-way illumination is that illuminator (6) and reflection shield (7) are housed in the both sides of glass plate (18), the reflector (15) of the high reflectance of reflection front light source incident ray perhaps is housed in the both sides of glass plate (18), also can be coated with or be stained with in the two sides of glass plate (18) color filter (4) and light shield layer (5) in addition.
Another main points are two kinds of liquid level gauges of above-mentioned said single, double look, all can be coated with or be stained with the diaphragm (3) that transparent teflon or mica constitute on the surface of contact that reflective liquid level glass plate (18) and liquid join.
Double colored indicator of the present invention is to constitute like this: the reflecting plate that is placed with look (as green) in liquid level gauge table body (10), scribble coating on the reflecting plate, heating between table body and glass (1), and with pressing plate and bolted, make it to become an airtight cavity, then with tested container UNICOM, the light that is sent by the illuminator of glass plate (18) both sides (the perhaps light that is penetrated by the high reflectance reflector that is used to reflect front light source incident ray) is incident upon two sides of glass plate right angle groove by (red) colour filter film (4).Gas part in the chamber, light will take place to penetrate outside the chamber after the total reflection on two sides of right angle groove (2), and total reflection also will take place on two sides of right angle groove by the light that the front illuminator that is contained in the pressing plate oblique upper sends, but its reflected ray will penetrate from two sides of glass plate respectively, the observer is from the outside surface (being on the display surface) of glass plate at this moment, and gas partly is bright redness in the cavity that will see.Liquid part in the chamber, total reflection can not take place in the light that penetrates from (red) colour filter film on the right angle groove, and therefore most light will enter liquid, and penetrate from relative side.And total reflection can not take place in the incident ray of sending to the front illuminator yet at this place, this part light will enter liquid, after (green) of reflector (11) look coating (12) upward reflects, passing through liquid again penetrates from glass plate display surface (17), at this moment, the observer will see that liquid partly is bright green in the cavity from the glass plate display surface.
The basic structure of the reflective monochromatic liquid level gauge of two-way illumination is identical with the former, just do not add front illuminator illumination, therefore, liquid in the cavity, it is characterized in that being equipped with illuminator (6) and reflection shield (7), and be coated with or be stained with colour filter film (4) and light shield layer (5) in the glass plate both sides in the both sides of glass plate (18).
The performance that has high temperature resistant, high pressure gas and liquid corrosion for the glass plate that makes liquid level gauge; central authorities on the surface that glass plate contacts with high temperature, high pressure gas open a right angle groove (2) along axis direction, and this right angle groove and circumferential surface spray or be stained with transparent teflon or mica sheet forms a protective seam.At two sides of glass plate dress or scribble transparent (as redness) colour filter film and opaque light shield layer, and illuminator and reflector are housed respectively, perhaps with the high reflectance reflector of reflection front illuminator incident ray.
The present invention and prior art ratio have characteristics high temperature resistant, high pressure gas burn into long service life, and the observer also can monitor liquid level at a distance.
