Abstract
The utility model relates to a double round tubes two-colour fluviograph, which comprises a quartz glass gas-liquid tube, lamp source, red and green filters, double cases, and a stainless steel round tube casing, wherein the gas-liquid tube is sheathed on the casing to form an inside and outside circle, and the red filter and green filter are at grade. The filters are made of red light paper and green light paper cemented between two blocks of colorless heat-resisting glass. The utility model has the advantages of simple and compact structure, low cost, convenient installation and maintenance, convenient processing, small size, favorable performance of reflection of light, higher pressurization, and high anti-rust and waterproof performance.
Description
The utility model relates to the device of liquid level indication.
At present in fields such as boiler, pressure vessel, chemical plant to the demonstration of High Temperature High Pressure liquid level, adopt double colored indicator more directly perceived, but all exist complex structure, bear pressure not high, processing loaded down with trivial details, deal is heavy, cost is high, filter glass can not be long wide, otherwise shortcomings such as necessary splicing.
The purpose of this utility model is the shortcoming that will overcome above-mentioned existing apparatus, provides a kind of relatively simple for structure, easy to process, and the pressure-bearing height is in light weight, the double colored indicator that cost is low.
Shell of the present utility model is to make of stainless pipe, and its advantage is to make simply, material-saving, and volume is little, and reflective function is good, can save special-purpose reflector.Less quartz ampoule of another diameter or high boron pipe are set as gas-liquid pipe in the middle of shell.On stainless steel casing, open a light hole, connect a dichroic filter framework with mechanical means above, so that the dismounting filter disc keeps in repair, red green optical filter is set on framework, at the outside of red green optical filter configuration light source, form by several incandescent lamps or daylight lamp, lamp box is equipped with in the outside, be provided with a viewing hood on the opposite in lamp source (between shell and the gas-liquid pipe) by Red lightscreening plate one side, on the shell that connects with this cover, open corresponding hole, so that operating personnel observe the color that presents in the cover by this hole.Red green optical filter be between two colourless heat resistant glass plates the gentle light paper of bonding one deck and one deck by one section green light machine-glazed paper and one section optical filtering ply of paper that the red light machine-glazed paper is formed, the width of red colored lamp machine-glazed paper is 4: 5 with the width ratio of green light machine-glazed paper, adopts the polymer agent bonding of fire resistant water resistant gas during bonding.
The utility model is not established reflector, viewing hood places shell, reached purpose simple and compact for structure, the red green optical filter adopts light paper and the bonding way of pyroceram to form, and has avoided the filter glass can not wide long restriction (must carry out splicing-in to wide long filter glass).
Embodiment of the present utility model is as shown in the figure:
Fig. 1 is the vertical structure figure of two circular pipe type two-colour fluviographs.
Fig. 2 is the lateral junction composition of two circular pipe type two-colour fluviographs.
Fig. 3 is the index path when being liquid in two circular pipe type two-colour fluviograph gas-liquid pipes.
Fig. 4 is the index path when being gas in two circular pipe type two-colour fluviograph gas-liquid pipes.
Fig. 5 forms synoptic diagram for dichroic filter.
(1) is the shell end cap among the figure, and (2) are sealing ring, and (3) are viewing hood, (4) be gas-liquid pipe, the shell that (5) are done for stainless pipe, (6) are the scale sign indicating number, (7) be lamp box, (8) are light source, and (9) are red green colour filter subassembly, (9.1) be red color filter, (9.2) be green color filter, (10) are colourless pyroceram, and (11) are gentle light paper, (12) be the red light machine-glazed paper, (13) are the green light machine-glazed paper.
In use in the gas-liquid pipe during full of liquid (as shown in Figure 3), the light that light source (8) sends sees through red green color filter (9) becomes ruddiness and green glow, be mapped to gas-liquid pipe (4), because full of liquid in the gas-liquid pipe, light reflects in gas-liquid pipe, the red green position intersects, and observes green in viewing hood (3).
Do not have liquid in gas-liquid pipe, when being gas, the light that light source (8) sends sees through red green optical filter (9) becomes ruddiness and green glow, and light does not directly reflect substantially by gas-liquid pipe (4), and red green two color bits are put constant, observe redness in viewing hood (3).
The utility model has following advantages through the operating practice proof:
1, compact conformation is simple, and is easy to process, and deal is light, and cost is low, and installation and maintenance are convenient.
2, external and internal compositions all is tubular, and volume is little, and reflective function is good, the pressure-bearing height.
3, adopt corrosion resistant material, waterproof good antirust property.
Claims (1)
- A kind of two circular pipe type double colored indicators that belong to the liquid level indication are made up of gas-liquid pipe, red green optical filter, light source, viewing hood etc., and it is characterized in that: gas-liquid pipe and liquid level gauge shell are pipe, and being sleeved on becomes inside and outside circle together; Red lightscreening plate and green color filter at grade, it be by red light machine-glazed paper and green light machine-glazed paper be bonded in two colourless and make between the heat resistant glass plate.
