Abstract
The utility model discloses a color fluid level gauge with a single mirror which can observe and monitor the liquid level and is suitable for monitoring the liquid level of a variety of boilers and chemical containers. The device adopts a specially made single mirror to replace a plane mirror and a prism, so the utility model has all the advantages of the reflection color fluid level gauge, the transmission color fluid level gauge or the transmission-reflection color fluid level gauge and simultaneously overcomes all the defects and insufficiency of the three above colour fluid level gauges. The utility model has the advantages of novel design, simple structure, true liquid level display, bright and clear color, large observation angle, with no need to adjust the light source.
Description
The present invention relates to a kind of improved level meter, particularly can observe and monitor the colored liquid level gauge of liquid level, it is applicable to boiler and other pressure vessel.
The direct-reading liquid level instrument that the observation liquid level is used develops into the widely used double colored indicator of countries nowadays by the plain boiled water table, and this liquid level gauge all is that two level crossings as observation window are set to certain angle, forms the sealing sap cavity.In order to improve observation effect, people try hard to increase angle between level crossing, but realize in structure and technical all being difficult for.People replace two level crossings with built-in prism for this reason, or replace level crossing with level crossing, prism, though structure and effect make moderate progress, but still undesirable.
The objective of the invention is to provide a kind of new single mirror colored liquid level gauge, it can not only observe liquid level effectively, and have modern design, simple in structure, colored bright-coloured, show characteristics such as liquid level is true.
Invention is achieved in that with single mirror and grooved seat forms the sealing sap cavity, utilizes in the chamber gas different with liquid refractive index, and the principle that fluid and the A mask of single mirror have the different angles of total reflection realizes the colour switching that the green vapour of liquid is red.The light beam that the two-phase color illuminates green mirror and red lens generation respectively by back light source and sidelight source obtains.Single mirror is made of Pyrex, is processed with the V-type groove in the above, two planes of groove, and note is made A face, B face.
The present invention is owing to adopt special single mirror, thereby keeps and developed the advantage of present various water level gauge, overcome their deficiency simultaneously.Modern design of the present invention, compact conformation is reasonable, and colored the demonstration becomes clear, and the observation liquid level is true, and observation angle is big.
Accompanying drawing is a sectional view of the present invention.
Below in conjunction with accompanying drawing invention being done one describes.
The present invention forms sealing sap cavity (not marking among the figure) by special single mirror (7), grooved seat (8) and gland (6), connects gland (6) and grooved seat (8) with screw (3).For sealing and protection, add sealing gasket (10) and cushion pad (9).Color shows by afterwards green mirror (2) is illuminated in light source (1), sidelight source (5), red lens (4) is realized.On single mirror (7) V-type groove (11) is arranged, xsect is V-shaped, and its two sides is A face and B face, and the A face is a reflecting surface.A face and B face angle are 55 °-75 °, are advisable with 65 °; Angle is 45 °-55 ° between A face and sightingpiston, is advisable with 50 °.When pressure below 1.6 MPas, temperature below 250 ℃ the time, single mirror (7) is used the Pyrex processing and fabricating, uses the calorize silicate glass when surpassing aforementioned condition instead.Grooved seat (8) is with No. 45 cast steels.After using resistant material instead, the present invention can be used for pressure vessels for the chemical industry, and its serviceability temperature is between subzero 100 ℃-200 ℃.
