Abstract
The utility model discloses a reflective and transmissive two-colored liquid level indicator used for displaying the liquid level. Because the previous fluid part which is displayed by the reflecting light is improved to be directly displayed by the transmission light, the liquid level display is made more clearly. The original sight glass of the liquid level indicator which is provided with a line of groove is improved to be provided with a spaced groove, so as to improve the pressure resistance.
Description
The utility model belongs to the device that shows liquid level change.
Existing reflective double colored indicator be by: the color reflective plate, the two side illuminant light backplates that have on sight glass body, front meter body, rear meter body, sight glass body side surface color coating and two side illuminant lights, the rear meter body of groove with the groove relative position constitute.During the liquid part of this liquid level gauge in showing groove, because liquid, vitreum two media are approaching, the light of side illuminator is injected the back and is seen through liquid, the light of small part reflexes to the colour reflective plate on the rear meter body on the inclined-plane of groove, by reflecting plate it is reflexed to inspection surface again.Because the light that is small part behind several secondary reflections, is presented on inspection surface, thereby, light intensity is lower, shows that the color of liquid part is also lighter, remote observation slightly, will make not obvious that boundary line between gas, the liquid two-phase sees, so make it can not carry out remote observation.
The utility model be for, change to show that the reflected light of liquid part is direct transmitted light, make the luminance brightness of the liquid part that observes big, dark, not only be fit to closely observation, also be applicable to the remote observation liquid level.
The utility model is realized by the following method.On the sight glass body, made with the corresponding inclined-plane of inspection surface be light reflection surface, and illuminator is housed in the side of liquid level gauge, scribble printing opacity colour film (or multiple chromatic colour glass sheet) with the sight glass body side surface that the illuminator homonymy is housed.The corresponding inclined-plane of sight glass body and inspection surface connects the middle table body have gas, liquid and optical channel, and its gas, liquid, optical channel are corresponding with the observation port of inspection surface, and the other end of gas, liquid, optical channel is shown the body seal channel in being close to by the one side of glass plate.The another side of glass plate scribbles printing opacity colour film (or multiple stained glass sheet), is had the rear meter body of transmitted light source lamp again by the middle part, and is continuous with the one side of glass plate chromatic colour film.At last, be added with front meter body, fasten as one by liner, fastening bolt sealing again in inspection surface.
Sight glass body on the liquid level gauge can be again the sight glass body that has a groove with before, make the groove that its groove is a compartment, it will make its intensity, withstand voltage degree increase, the liquid level that is not only applicable on the low-voltage equipment shows, can be suitable for carrying out on the middle and high pressure equipment simultaneously liquid level again and show.
The utility model is in carrying out the liquid level procedure for displaying: when showing the gas part, because gas, vitreum two medium difference are bigger, and the colorama that the sight glass side sees through, after injecting the sight glass body, circuitous inclined-plane to the sight glass body, the overwhelming majority is to reflect, and it is reflexed to inspection surface; Simultaneously,, see through colour film and inject gas, liquid, optical channel by the light that the illuminator on the rear meter body penetrates, the inclined-plane of the circuitous sight glass body of its colorama that sees through, also with the reflecting of the overwhelming majority, the side of reflected back passage, and can not see its light in inspection surface.When showing the liquid part, because liquid, vitreum two media are approaching, the side illuminator injects that the light of sight glass body is circuitous not to be reflected to sight glass body inclined-plane, directly passes the inclined-plane and enters liquid; And being positioned at transmitted light source lamp on the rear meter body, the light of ejaculation sees through colour film, is incident upon the colorama on sight glass body inclined-plane by gas, liquid, optical channel, reflection does not take place too and directly passes the inclined-plane and is incident upon inspection surface.What see in inspection surface thus, is gas, liquid two parts that the light of two kinds of different colours shows.
The utility model is described further by following accompanying drawing.
Accompanying drawing 1, have one to be the reflection on the inclined-planes of 45 degree, the drawing in side sectional elevation of transmission bicolor liquid level indicator for triangular prism sight glass body and sight glass body with inspection surface.
Among the figure, (1) is that front meter body, (2) are illuminator backplate for liner, (10) for side illuminator, (12) for glass plate, (7) that scribble green film (9) in one side for triangular prism sight glass body, (5) that scribble red color film (8) in a side for rear meter body, (4) that the middle part has transmitted light source lamp (11) for middle table body, (3) that have gas, liquid, optical channel (6).
During this liquid level gauge work, be the part of gas in gas, liquid, the optical channel, the circuitous sight glass body of the ruddiness that the side is injected inclined-plane, its ruddiness will reflex to inspection surface; Illuminator sees through the green light that green film is injected on the rear meter body, circuitous sight glass body inclined-plane and reflect the side of return-air, liquid, optical channel.In gas, liquid, the optical channel is the part of liquid, and the circuitous sight glass body of the ruddiness that the side is injected inclined-plane does not reflect, and enters liquid but pass the inclined-plane; Illuminator sees through the green light that green film is injected on the rear meter body, and circuitous its sight glass body inclined-plane is to pass and present inspection surface equally.
What thus, inspection surface was seen is gas, liquid two parts that red, green color shows.
Accompanying drawing 2, be the front view of four rib sight glass cylinders of compartment groove.
Among the figure, (1) is sight glass body, (2) for cell wall and sight glass side, end face are miter angle and groove two ends respectively is that groove, (3) of half cone are the transverse ridge of spaced trenches.
Accompanying drawing 3, be the A-A cut-open view of four rib sight glass cylinders of compartment groove.
Among the figure, (1), (2), (3) are as described in the accompanying drawing 1.
Accompanying drawing 4, be the B-B cut-open view of four rib sight glass cylinders of compartment groove.
Among the figure, (1), (2) are as described in the accompanying drawing 1.
The utility model, owing to be direct transmission-type glory with the liquid partial display, so that liquid level shows is more obvious, also very clear even if the remote observation liquid level changes. Owing to use the sight glass body of the groove of compartment, its liquid level gauge shown applicable to basic, normal, high being installed with for upper liquid level.
Claims (4)
1, a kind of reflection, transmission bicolor liquid level indicator that is used for the liquid level demonstration, be to constitute by: front meter body, sight glass side color coating, side illuminator, backplate, liner, it is characterized in that: the sight glass body have one with the corresponding light reflection surface of inspection surface, its light reflection surface connects the middle table body that has gas, liquid, optical channel, by glass plate blanket gas, liquid, optical channel, another scribbles the rear meter body that the transmitted light source lamp is equipped with at colored face connection middle part glass plate again.
2, reflection according to claim 1, transmission bicolor liquid level indicator is characterized in that: the light reflection surface on the sight glass body is the inclined-plane that is miter angle with inspection surface.
