The water level of pressing following steam boiler to use in the present score glass tube formula and glass plate type two big classes.The glass tubular type is used for low pressure steam boiler; Glass plate type is used for, low pressure steam boiler.The glass plate type water level gauge is divided into board-like three kinds of transmission (reflection) glass plate type, transmission ball float glass plate type and dichroic glass again, by Chinese specialized standard " ZBN12004-88 " clearly regulation is made in its technical requirement.

Key component on the boiler water gauge is a glass elements transparent, that can observe water level.The glass elements of glass tubular type water level gauge be inside and outside all be circular glass tube, with no plug drawing method manufacturing; The glass elements of various glass plate type water level gauges is glass plates, is divided into two kinds of flat and open flume types by " QB776-80 " standard.Flat glass pane surface is level and smooth; The open flume type glass plate then has groove in glass pane surface.Transmission (reflection) glass plate type and transmission ball float glass plate type water level gauge are shallow and close with the groove of glass plate; The glass elements of the existing board-like water level gauge of various dichroic glass, or on glass plate, have the groove of forming by two special angle planes, or on glass plate, be provided with the inclined-plane of special angle, do not have inner trough structure.

The double-colored Presentation Function of existing boiler two-colour fluviograph all relies on or the special use optical filtering light source of two kinds of different colours; Or special-purpose ordinary light source sees through the color filter of two kinds of different colours, with the ray cast of two kinds of colors to glass elements, with effects such as the reflection of optical principle process, transmissions, vapour, water two-phase are shown with different colors, and glass elements originally shines not have directly down in ordinary light source vapour, water two-phase is divided into the function that two kinds of different colours show.

Existing boiler two-colour fluviograph is subjected to the restriction of glass elements 26S Proteasome Structure and Function, and following shortcoming is arranged:

1. because the vapour, the aqueous medium that have uniform temperature and pressure are the outside surface circulations at glass elements, it longitudinally is the metal table body structure that the glass elements length direction comes clamping, seal glass element that water level gauge must have, this structure heaviness, complexity and poor sealing performance.

2. water level gauge must possess the special light source of electric pressure safe in utilization on one-piece construction; The optical filtering power supply or the optical filter of two kinds of colors; Two kinds of color light are poly-to glass elements and the reflector that adds intense light irradiation; Prevent the light structures such as influencing the water level gauge of observing effect outer cover that leaks, complex structure.

3. be subjected to metal table body, the isostructural restriction of outer cover, the water level gauge range of observation is little, can only be from one-sided observation water level; Vertically visual range does not reach the regulation of China " ZBN12004-88 " standard, and laterally visible angle only about 20 °, can not satisfy boiler attendance personnel's requirement.

4. because of being subjected to structural limitations and use special light source, water level gauge lost efficacy immediately when power failure or power fail, jeopardized the safe handling of steam boiler.

The purpose of this utility model is: design a kind of novel special glass element and upgrade existing steam boiler two-colour fluviograph glass elements, for two-colour fluviograph overcomes above-mentioned shortcoming, updating creates conditions, the security that makes two-colour fluviograph simplification of new generation, lightness, meets national standard, optimizes usability and improve steam boiler.And the utility model can be used on double-colored demonstration of pressure vessel liquid level and the double-colored monitoring arrangement of pipe interior liquid.

The purpose of this utility model is achieved in that

1. the utility model profile is square post, longitudinally center line has a square hole post in square post, be contained on the water level gauge that vapour, aqueous medium circulate when using in the square hole post, just change into both ends of the surface clamping of the present utility model, sealing by vertical clamping, the sealing of existing two-colour fluviograph glass elements, can cancel metal table body structure, make it: simplification, lightness and improve sealing property.

From the two ends clamping, seal pressure of the present utility model, can be by using water level gauge of the present utility model with a metal framework that is enclosed within the utility model outside, apply by helicitic texture, because long-pending only need of the lateral cross section of metal framework satisfied the needs that bear pulling force by intensity calculating, can design to such an extent that fully open up visual field and accept illumination, can observe water level from relative both direction, laterally each direction maximum can have 60 ° of visual angles; Longitudinal length of the present utility model can design by reaching and suitably surpassing China " ZBN12004-88 " standard, because sealed at both ends, the utility model length promptly is the vertical visual range of water level gauge, reaches China's standard code, has optimized usability.

3. the utility model square each outerplanar of post and each inner plane of square hole post tilt 45 °, and relative two outerplanars of square post are sightingpiston; Two outerplanars with redness relatively in addition, and outside ordinary light source filters through the red coloration plane and is red light irradiation to each inner plane of square hole post, and ruddiness can reflect to sightingpiston when being vapour by medium in optical principle: the Kong Zhu, and promptly vapour phase shows red; Ruddiness can not be reflected when medium was water in the Kong Zhu, and promptly water shows the transparent whites of water, and promptly the utility model has directly under the ordinary light source irradiation vapour, water two-phase are divided into the function that two kinds of different colours show.Adopt two-colour fluviograph of the present utility model no longer to need structures such as special light source, color filter, reflector, outer cover, use on-the-spot illumination in boiler room or lamp can show double-colored water level, make to simplify the structure.

4. adopt two-colour fluviograph of the present utility model not to be blocked,, all can observe water level incessantly, improved the security performance of steam boiler with lamp or any temporary lighting having a power failure or can not losing efficacy during power fail because of most of sightingpiston and sensitive surface.When being employed on demonstration of pressure vessel liquid level and the pipe interior fluid monitoring device, also can reach same effect with above-mentioned same principle.
