Abstract

The utility model discloses a boiler water gauge, which is characterized in that an unicolor color lamp is arranged at the lower front of a glass pipe, the illumination angle of the color lamp rightly lights on the whole glass pipe, a colored lining board is arranged on the back surface of the glass pipe, and the inner hole of the glass pipe can be circular, convex, concave, or corrugated. When water in the glass pipe, a ring of light can be formed after the junction of steam and water, or a colored light beam can be formed on an optic plate. The utility model is suitable for being used on medium and small sized boilers.

Description

Monocolour display hydrological gage

The utility model belongs to the indication and the measurement of liquid levels, is specially adapted to the demonstration of steam boiler water level liquid level.

Domestic and international at present comparatively advanced being used to shows that the instrument of boiler water level and some pressure vessel liquid levels is a two-colour fluviograph, its two-colour fluviograph is with red, green two kinds of colors show liquid level position, two-colour fluviograph is by container, observation window, light source and inequilateral right angled triangle prism are formed, utilize the different principle in the refraction angle of light in different medium, refraction action by prism, in transparent observation window, can show water outlet and steam two medium present positions, mark respectively by red green two kinds of colors, this water level meter shows that liquid level is clear, the division is clearly demarcated, but following deficiency is arranged with regard to its two-colour fluviograph, structure is complicated, clean inner difficulty, involve great expense, be not suitable on middle-size and small-size stress-free boiler, using.

For solving above deficiency, the utility model provides a kind of monochromatic water level meter that shows, utilize the principle of light refraction angle difference in different medium, can know the position that demonstrates liquid level with a monochromatic source with once the glass tube that is filled with water, reaching simple in structure, easy to install, cost is low, the outstanding effect purpose.

Design of the present utility model is the position that the water level meter is housed on existing boiler, a vertical glass tube is installed, require high temperature high voltage resistant, the connection of its glass tube is to be connected with pipeline with boiler respectively at the two ends of this glass tube, one manually-operated gate is housed respectively on the pipeline at two ends, and it is fastening between the glass tube with screw, sealing, in case inner water and steam overflow, under glass tube, also adorn a manually-operated gate, open two valves of pipeline, water in the boiler is because air pressure flows in the glass tube naturally, liquid level position is exactly a water surface site in the boiler in the glass tube, inferoanterior at glass tube is (red facing to the colored lights that glass tube is equipped with a monochrome, green or incandescent lamp), the illumination angle of colored lights shines on the whole glass tube just, the glass tube endoporus can be made following several shape, one of them is circular, with the exception of this, be circular-arc near light one side, can convex facing to the light opposite side, concavity or corrugated, at the back side of glass tube, carry light one side one colored liner plate is housed, red green all can, vertical welding is on glass tube and pipe that boiler is connected, colored lights like this, glass tube and liner plate are in same vertical plane.

Its operation principle is when the glass tube endoporus is circle, colored lights shines on the glass tube and presents a colored ring of light at the interface place of water and vapour, when the glass tube endoporus is other three kinds of situations, during its surface of light-illuminating, carry out various reflections, therefore do not observe the color of glass tube back, after injecting water in the glass tube cavity, because the refractive index of glass and water is close, therefore light just can see through glass tube and water, be penetrated into the back side of glass tube, at the autochromatic plate (red green or other color) that glass tube is placed with later, just can observe the colour (red green or other color) at the back side when in the glass tube water being arranged, anhydrous place just be can't see, so just can foil that one section in water is arranged in the glass tube is a colored water column, that a kind of glass tube endoporus all can be known the position that marks water and steam in the boiler.

The utility model and its two-colour fluviograph relatively have following advantage, simple in structure, liquid and gas interface clear display, low price, are adapted at promoting the use of on the medium small boiler.

The accompanying drawings embodiment:

Fig. 1 is the monochromatic water level meter structure principle chart that shows.Know by Fig. 1, monochromatic water level meter is housed on boiler 8,1 and 6 is respectively the manually-operated gate that is connected with boiler pipe up and down, 1 is penstock, 6 is the steam valve door, 5 is the glass tube of high temperature high voltage resistant, and 2 is the valve of glass tube below, uses as blowdown, 3 is colored lights, the lucky full illumination of light is to glass tube 5, and 4 is the glass liquid in pipe, and 7 is the interface of liquid and gas, 9 is colored liner plate, vertical welding remains static when liquid and gas pressure balance on glass tube 5 and pipeline that boiler 8 is connected, when pipe orifice when being circular, just present a colored ring of light at the interface place 7 of liquid and gas, colored identical with the colored lights color, all can see all around, when pipe orifice is other three kinds of shapes, liquid in the pipe just can be the water column of a colour, water column is colored identical with the liner plate color of back, and no matter the sort of pipe orifice all can get the water-level observation in the glass tube absolutely clear.

The advantage of present embodiment is simple in structure, observes clear, successful.

Claims (2)

1, a kind of monochromatic water level meter that shows, manually-operated gate was formed about the pipeline that it is connected with boiler by glass tube reached, the utility model is characterised in that the inferoanterior at glass tube 5 is equipped with the colored lights 3 of a monochrome, a colored liner plate 9 is housed at the back side of glass tube 5, vertically on glass tube 5 and pipeline that boiler 8 is connected, and colored lights 3, glass tube 5 and liner plate 9 are in same vertical plane.

2, by the described monochromatic water level that shows of claim 1, it is characterized in that the inner hole surface of glass tube 5 can be circle, convex, spill and corrugated to light one side.
