Abstract
The utility model discloses a water level gauge with red and green display, which is a device for monitoring liquid level variation in a steam boiler. The water level gauge is composed of a back plate, a main body, a corner plate, a colored filter plate, a light source lamp, optical glass, etc. The water level gauge with red and green display cancels a colored reflecting plate and changes reflection light at the liquid level displaying part into transmission light to make the display between the liquid situation and the gas situation clear and distinct with a clear interface in the display process and make the observer judge accurately at a larger angle in a farther distance.
Description
The utility model relates to a kind of device that monitors the steam boiler liquid level change.
For, the water level situation of understanding boiler internal need be installed gauge glass usually on boiler.
At present, existing reflective double colored indicator is by the sight glass body that has groove, and with the color reflective plate of groove relative position, two side illuminant light backplates constitute on front meter body, rear meter body, sight glass body side surface color coating and two side illuminant lights, the rear meter body.Because water, vapour, glass all are the water white transparency object, the light of side illuminator is injected the back and is seen through liquid, and 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 and sees the side.Because the light that is small part behind several secondary reflections, is presented on inspection surface, thereby light intensity is lower, show that the color of liquid part is also lighter, remote observation will make gas slightly, and the boundary line between liquid is seen not obvious.And the colour reflective plate is after using 3～5 days, owing to its surface adsorption incrustation scale makes this gauge glass inspection surface smudgy, needs slottingly can use after unloading cleaning, and this cleaning is more time-consuming bothersome.
The purpose of this utility model is: cancellation colour reflective plate, changing the reflected light that shows the liquid part is direct transmitted light, utilize water and glass two media approaching, light is at the interface of gas and glass total reflection principle, utilize the reflex of optical prism, the his-and-hers watches chamber does not have water section, observes redness and is coated with face and takes on a red color; Utilize the transmission effect of optical prism, be coated with face and be green there being water section to observe green.
Below in conjunction with accompanying drawing 1 its principle of work is described:
This is red, the clear water bit table is mainly by sidelight source (1), red filter plate (2), observation window (3), back light source (4), green filter plate (5), square type mirror (6), backboard (7), main body (8), rib type mirror (9), gusset (10), passage formations such as (11).Square type mirror (6) is embedded in the Baltimore groove of backboard (7), and rib type mirror (9) is embedded in the leg-of-mutton groove of gusset (10).Lining is with sealing gasket between main body (8) and square type mirror (6) and backboard (7), equally, lining is with sealing gasket between main body (8) and rib type mirror (9) and gusset (10), and with gusset (10) and main body (8), it is an integral body that backboard (7) is linked to be with main body (8) with screw.
The utility model is on the basis of original red, green bi-colour water gauge, improved inner structure, make it simple and compact for structure, the light of the liquid that parts are few, make inspection surface, gas part, brightness is big, and is dark, make the observer not only at a distance, and clearly offer an explanation out red, green two kinds of colors in a bigger angular range, thereby, can draw accurately and judge water, the vapour two states of boiler.
Below by the embodiment accompanying drawing the utility model is further described.
Fig. 2, when being marked with water in passage (11) chamber, because water and glass two media are approaching, see through square type mirror (9) through green filter plate (5), the green light (12) of passage (11), owing to water is arranged in the passage (11), can see green light (12) from view window (3) through rib type mirror (9); And can not see through red filter plate (2), see through the red light (13) of rib type mirror (9).
Fig. 3 when in passage (11) chamber when anhydrous, injects the red light (13) of rib type mirror through red filter plate (2), owing to be gas in the passage (11), red light (13) will reflect, and reflection red light (13) is presented in view window (3).And, see through square type mirror (6) through green filter plate (5), by passage (11), be mapped to the green light (12) of rib type minute surface, because in the passage (11) is gas, green light (12) will reflect, so can not see green light (12) at view window (3).
Claims (5)
1, a kind of red clear water bit table, it is the device that is used to monitor the steam boiler liquid level change, it is characterized in that by backboard (7), main body (8), gusset (10) constitute, between backboard (7) and main body (8), be embedded with square type mirror (6), be embedded with rib type mirror (9) at gusset (10), and colored filter plate (2), (5) be housed in the outside of gusset (10) and backboard (7).
2, a kind of red clear water bit table according to claim 1 is characterized in that having on the gusset (10) rib type groove.
3, a kind of red clear water bit table according to claim 1 is characterized in that in colored filter plate (2), (5) outside illuminator (1), (5) being housed.
4, a kind of red clear water bit table according to claim 1 is characterized in that square type mirror (6), rib type mirror (9) are optical glass.
5, a kind of red clear water bit table according to claim 1 is characterized in that colored filter plate (2), (5) are plastics.
