Abstract

The utility model relates to a hole type double-color water gauge, 5-7 circular through holes are arranged on a gauge column, each through hole is composed of a circular plate glass block and a glass block with a sunk conical surface, the apical angle of the shaft cross section of the conical surface is 90 DEG, and a lens and a reflecting mirror are formed, which causes the water phase is displayed in green and the steam phase is displayed in red. The utility model is used for viewing steam drum water level of a boiler.

Description

Hold double-colour water gage

The utility model is the glass tube of reflective bi-colour water gauge or glass plate to be changed over the array glass blocks assemble, and is used for showing a kind of cellular type bi-colour water gauge of boiler drum level.

Common reflective bi-colour water gauge, oversize up and down because glass tube or glass plate are an integral body, can not bear high pressure.Therefore, this bi-colour water gauge generally can only use on the low-voltage and medium voltage boiler.

In order to address this problem, external at present existing cellular type bi-colour water gauge, it is to utilize light to realize with the different principle of refractive index in the vapour phase at water.But this gauge glass structure more complicated, processing difficulties, and because the carbonated drink corrosion, it is unclear to thicken in the relatively shorter time.

The purpose of this utility model is to utilize the principle of light transmission and reflection to show double-colored.This gauge glass is owing to be to be assembled by the less glass blocks of several piece diameter, and force-bearing situation is better, thereby can bear high pressure, uses applicable to high-pressure boiler.

Illustrate below in conjunction with Fig. 1, Fig. 2 how the purpose of this utility model realizes.

Fig. 1 is the general assembly drawing of the utility model cellular type bi-colour water gauge.This gauge glass mainly is made up of table post ［ 1 ］, last valve ［ 2 ］, lower valve ［ 4 ］, guard shield ［ 29 ］, lampshade ［ 28 ］, communicating pipe ［ 3 ］ and blowoff valve ［ 5 ］.The boiler steam is by last valve ［ 2 ］, and water enters table by lower valve ［ 4 ］ and lives ［ 1 ］, by the principle demonstration water level of linker.

Have 5-7 manhole ［ 30 ］ on the table body ［ 25 ］, be communicated with up and down between each through hole, the diameter of through hole is 20-40MM.Vertical by axial line with the plane of glass blocks ［ 10 ］, ［ 21 ］.Each through hole is combined with mica sheet ［ 11 ］, packing ring ［ 12 ］, ［ 13 ］, ［ 27 ］, chip shield ［ 26 ］, gland ［ 9 ］ and mica sheet ［ 22 ］, packing ring ［ 23 ］, ［ 24 ］, ［ 16 ］ chip shield ［ 19 ］, gland ［ 18 ］ respectively by glass blocks ［ 10 ］, ［ 21 ］; be fastened on the table body ［ 25 ］ with bolt ［ 7 ］ and ［ 17 ］, form lens and catoptron.Glass blocks ［ 10 ］ is circular sheet glass piece, and specification is diameter 20-50MM, thickness 10-30MM.Glass blocks ［ 21 ］ is the circular glass piece, and a sunk circular conical surface is arranged on the glass blocks, and the specification of glass blocks ［ 21 ］ is diameter 30-60MM, thickness 15-40MM, the high 8-15MM of circular conical surface is vertical with the glass blocks plane, bottom surface radius 8-15MM, 90 ° of shaft section drift angles.

After energized, the light of bulb ［ 6 ］ is shone on the green glass sheet ［ 8 ］ by reflective mirror ［ 14 ］, at aqueous phase, green light sees through glass blocks ［ 10 ］, ［ 21 ］ and mica sheet ［ 11 ］, ［ 22 ］, arrive green in the gauge glass top view, in vapour phase, green light is owing to reflection does not observe; Simultaneously, the light of bulb ［ 6 ］, shine on frosted glass circle ［ 15 ］ and the red glass circle ［ 20 ］ by two reflective mirrors ［ 14 ］ respectively, in vapour phase, red light is because the reflection of glass blocks ［ 21 ］ circular conical surface is arrived red in the gauge glass top view, then see through glass blocks ［ 21 ］ and do not observe at the aqueous phase red light, make the gauge glass viewport present redness when vapour phase, present green when water, the water level boundary line is fairly obvious.Simultaneously, when the boiler-steam dome full water, all viewports then show green, and when lack of water, all viewports then show redness, and the very easy boiler-steam dome of distinguishing is the situation that is in full water or lack of water, thereby can avoid accident to take place effectively.
