Description

Double-colour hydrological gauge with double reflection-side

The utility model relates to a kind of Industrial Boiler that is applicable to, the double-reflecting face two-colour fluviograph of electricity generation boiler, high-pressure heater, degasifier and water tank, storage device etc.

Water level gauge is requisite in the equipment such as Industrial Boiler, but desirable water level gauge is also few in number, glass tubular type two-colour fluviograph, China used since 1987, its structure is triangular in shape in the glass tube, semicircle and pentagonal single reflecting surface, in use be subjected to high temperature, water, the corrosion of vapour medium, reflecting effect is faded, make red like this, green glow is unintelligible, so that lose red, green contrast, particularly leg-of-mutton glass tube water level gauge, viewing angle has only 30 °, the width maximum has only 6 millimeters, and foursquare glass tube utilizes adjacent right-angle side as inspection surface, and sightingpiston is corresponding has widened some, but do not guarantee pure red, Yin Qibi has one jiao of corresponding inspection surface, slightly after the corrosion, certainly leads to two red lines and adds a green line, so just lost red should the producing effect of light green vapour, semicircular glass tube is with leg-of-mutton basic identical, and its two reflecting surface is still an angle except that inspection surface is curved, and is identical with leg-of-mutton acute angle; Foursquare glass tube must have 90 ° angle, more than three kinds of abilities of bearing pressure relatively poor, use dangerous, though it is better that pentagonal glass tube bears pressure, but with foursquare equally exist slightly corrosion is arranged after, will produce the phenomenon that two red lines press from both sides a green line, water level gauge is malfunctioning, observation error makes to boiler safety to be used for danger.

The purpose of this utility model provides a kind of easy to use at the problems referred to above to the public exactly, is easy to observation, safety, red, green clearly demarcated double-reflecting face two-colour fluviograph.

The purpose of this utility model is to realize like this, utilize the principle of the rectilinear propagation and the reflection of light, adopt in the glass tube hollow be rectangle (or isosceles trapezoid and parallelogram), and on external three faces of the table of glaze pipe, open the red of observation port and different colours, green entry portal and reflected light plate, slot and observation port are 45, because the refractive index of steam is different, vapour in glass tube, when in the aquaporin being the gas medium, ruddiness reflects outside the observation port through two reflectings surface, green glow is refracted on the table body wall, what at this moment see from observation port is red (expression vapour), when being water in the steam-water channel in the glass tube, the ruddiness direct projection is on the table body wall on opposite, and the green glow direct projection is in observation port, and what at this moment seen is green (expression water).

From the above, novel structure of the present utility model, it is convenient, accurate, clear to observe, the color longer duration, colourity is clearly demarcated, very helps the observation of water, vapour position, makes the safe operation of boiler more reliable.

Below in conjunction with accompanying drawing structure of the present utility model and principle of work are elaborated.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the front elevation of glass tube.

Fig. 3 is transverse sectional view a, b, the c of glass tube.

By shown in Fig. 1 to 3, architectural feature of the present utility model is that glass tube 2 is outer for circular, interior hollow is rectangle or the steam-water channel 3 of isosceles trapezoid and parallelogram, be installed in center through the table body 1 after the processing, table body available metal or plastic or other material are made, the length of glass tube and steam-water channel, thickness is looked the needs of steam face size of observation boiler and difference, can make the product of plurality of specifications during production, two parallel long limits of steam-water channel 3 are double-reflecting face 11, be 45 ° of-48 ° of angles with the axis of showing the observation port 12 on the body 1, if rectangle steam-water channel, two parallel long limits are double-reflecting face 11, if the steam-water channel of isosceles trapezoid, last bottom is a double-reflecting face 11, if steam-water channel is a parallelogram, double-reflecting face 11 is last, following parallel long limit, the glass tube two ends add the four-layer seal ring and add gland and compress two ends, be connected on the by-pass valve control by connecting pipe, be installed on the liquid reservoir and (do not draw among the figure), green filter glass 4 is installed in the outside that the same observation port 12 relative green glows of showing on the body 1 are injected hole 5, red filter glass 6 is installed on the table body 1, inject the outside in hole 7 with the vertical redness of observation port, table body 1 usefulness bolted is in the side angle sealing (as the lower left corner) of rectangle light-source box 10, light source 8 places the diagonal angle of table body 1, two reflectors 9 place the front of light-source box 10 interior red filter glasses 6 and green filter glass 4, like this after light source is connected, the light of light source 8 utilizes reflector 9 to pass through red filter glass 6 respectively, the ruddiness and the green glow of green filter glass 4 are injected hole 7 by ruddiness respectively, green glow is injected hole 5 and directly is mapped on the glass tube 2, when 3 li of steam-water channels in the glass tube are the vapour medium (transmittance of vapour and flint glass and color are similar substantially), ruddiness is through two long limit reflectings surface 11 of glass tube steam-water channel, reflex on the observation port 12, green light reflexes to red light and injects on the opposite table body wall in hole 7, what at this moment see from observation port is red, when being full of aqueous medium in the glass tube steam-water channel, the ruddiness direct projection is on the table body wall on opposite, and the green light direct projection is on observation port, and what at this moment see is green.

Can be clear that by said structure and operation principle situation, the utlity model has obvious advantage:

1, ruddiness reflexes on the observation port by two long limits of glass tube steam-water channel, and ruddiness is strong, and than other two-colour fluviograph brightness raising 40%, the time of red-green glow contrast will prolong one times, relatively prolong one times the service life of product;

2, redness is strong and green clearly demarcated, and just carbonated drink is clearly demarcated, clear;

3, do not have acute angle in the glass tube, bear the pressure height, safe and reliable, long service life;

4, observation visual angle is big, can reach 50 ° more than the angle, spies on face width, goes out more than 30% than triangle is wide, can reach the 9-10 millimeter, is convenient to operation, and is accurate, safe and reliable.

Widespread use of the present utility model will bring bright prospect for the safe handling of Industrial Boiler, electricity generation boiler, height well heater, degasifier and water tank, storage device etc.
