Abstract
Disclosed is a reflective water level gauge view mirror with two strip salient, which belongs to the boiler water level display technology. One surface of the water level gauge view mirror contacts water and is provided with two strip salient which are slightly lower than the sealing surface. The cross sections of the strip salient are two triangles with a vertex angle of ninety degrees and the two right angle surfaces form two reflection surfaces. The water level gauge shows white without water inside and black with water inside, which forms a clear interface. The view mirror is simple for processing, convenient for installation and low in cost.
Description
Technical field
A kind of water level gauge visor provided by the utility model belongs to the boiler water level display technique.
Background technology
The water level gauge visor is an indispensable element on the water level gauge, and its performance directly influences the water level display effect.Existing water level gauge visor has transmission-type and reflective two kinds, installs to that steam interface, back is difficult to differentiate on the water level gauge, causes the boiler water shortage accident easily.
Summary of the invention
The utility model purpose is: provide a kind of reflecting surface big, the clearly demarcated a kind of reflective water level gauge visor in steam interface.
Scheme of the present utility model is: the one side of water level gauge visor contact water has two strip bulges more lower slightly than sealing surface, and the xsect of strip bulge is two triangles, 90 ° of drift angles, and leg-of-mutton two right angle faces form two reflectings surface.When in the water level gauge when anhydrous, because the effect of reflecting surface is a white looking the liquid direction observed, when in the water level gauge water being arranged, because the refractive index of visor and water is close, the reflecting surface of visor is ineffective, is black looking the liquid direction observed.Water level changes in the water level gauge, looking the also variation synchronously of the observed color of liquid direction, obtains the clearly demarcated beneficial effect in steam interface.
Description of drawings
Fig. 1 is a kind of reflective water level gauge visor; Fig. 2 is the A-A cut-open view of Fig. 1.
Embodiment
To the utility model optimal way, be described as follows in conjunction with the accompanying drawings.
Two strip bulges (1) are arranged on the reflective water level gauge visor, and strip bulge (1) drift angle is 90 °, and two right-angle sides (2) form two reflectings surface (2), and strip bulge (1) is more lower slightly than sealing surface (3).When in the water level gauge when anhydrous, light is injected from looking liquid direction (4), and the face that is reflected (2) backspace is that white shows looking liquid direction (4) observed; When in the water level gauge water being arranged, because water level gauge visor refractive index and water refractive index are close, the reflecting surface of visor (2) is ineffective, and light directly enters in the water, because of the background in the water is a black, so be black looking liquid direction (4) observed.Water level changes in the water level gauge, is looking the also variation synchronously of the observed steam of liquid direction (4) interface.
Claims (2)
1, a kind of reflective water level gauge visor that two-hump is arranged is characterized in that the one side of water level gauge visor contact water has two strip bulges more lower slightly than sealing surface.
2, a kind of reflective water level gauge visor that two-hump is arranged according to claim 1, the xsect that it is characterized in that strip bulge is two triangles, 90 ° of drift angles, leg-of-mutton two right angle faces form two reflectings surface.
