Description
Technical field
The utility model relates to liquid level monitoring equipment field, particularly a kind of light-operated explosion-proof liquid level meter that is widely used in various media fluid level monitorings.
Background technology
The explosion-proof night vision liquid level gauge of existing double-colored quartz tube type, it partly is made up of valve, table body, quartz ampoule, light source etc., because the problem of structure, it has following defective: the one, because of light source and colour glass plate are installed together, cause protecting against shock and thermal insulation poor, reduce the brightness of light source, influenced its observation effect; The 2nd, protective cover is not set and protects fluorescent tube, so do not possess protecting against shock, dustproof and explosion-proof function; The 3rd, owing to do not have the heat-resistant coating layer on the circuit board, so heatproof is poor.In a word, use dangerously, observation effect is poor.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of safe in utilization, light-operated explosion-proof liquid level meter that observation effect is good is provided, this liquid level gauge can all can be observed various mesolow reservoirs in the industries such as oil, chemical industry, jar interior liquid level well under any light environment.
The technical scheme that its technical matters that solves the utility model adopts is: be provided with valve, liquid level display body and the Lights section, be provided with quartz ampoule, colour glass plate in the liquid level display body, wherein, light source is isolated the rear that is placed on colour glass plate, light source is by light tiles and protect fluorescent tube and form, light tiles is embedded in protects in the fluorescent tube and parallel with colour glass plate, protects lamp tube ends and links to each other with securing member, and securing member links to each other with the shell of liquid level display body.
Principle of work of the present utility model is: flange corresponding on the flange on the valve and the container is connected to form linker, directly shows liquid level according to law of connected vessels.The Lights section can be regulated the brightness that colour glass plate filters automatically according to the bright and dark light at scene, makes observation effect the best, has solved the difficult problem that night for a long time or light do not observe liquid level when dark.
The utlity model has following advantage:
One. safe in utilization, explosion-proof performance is good.Its manufacturing meets GB3836.1-2000 " explosive gas atmosphere electrical installation first: general requirement ", GB3836.2-2000 " explosive gas atmosphere electrical installation second portion: flame-proof type
", GB3836.3-2000 " explosive gas atmosphere electrical installation third part: increase peace
" middle relevant requirements.
They are two years old. because of light source independently is provided with, can heat insulation and heatproof, and have explosion prevention function.
They are three years old. owing to adopted polycarbonate to protect fluorescent tube and dust cover, so have the function of protecting against shock, explosion-proof, dustproof and heatproof.
They are four years old. and on the basis of original cold light film light source, set up a kind of luminescent aerosol sheet laser, had dual luminous effect.These two kinds of light sources can be fitted together, and also can independently use.Wherein, latter's light source is applicable under the low temperature environment and uses that cost is lower, thereby can make the user select to use according to actual conditions.
They are five years old. because circuit board is provided with the heatproof coating, thereby improved the security of using.

Embodiment
Structure of the present utility model is as shown in Figure 1 and Figure 2: be provided with valve 1, liquid level display body 10 and the Lights section, be provided with quartz ampoule 16, colour glass plate 12 in the liquid level display body.Described light source, by light tiles 13 with protect fluorescent tube 11 and forms, isolation is placed on the rear of colour glass plate.Light tiles is embedded in protects in the fluorescent tube, and parallel with colour glass plate.Protecting lamp tube ends links to each other with securing member 14.Securing member links to each other with the shell of liquid level display body.
As Fig. 1, Fig. 2, shown in Figure 3: above-mentioned light tiles 13, can adopt cold light film or luminescent aerosol sheet; Perhaps, can adopt cold light film and luminescent aerosol sheet.The cold light film two ends are respectively by an anti-explosion cable that is passed by binding post, are connected with the output terminal of holding circuit on the circuit board in the explosion-proof electric apparatus box 3, and therefore, the working power of cold light film can be provided by this holding circuit.On the shell of liquid level display body, its front is a rule 5, is cover plate 6 afterwards; Link to each other with explosion-proof electric apparatus box 3, binding post 4 above it, another binding post (accompanying drawing is not drawn) is threaded with the binding post hole 22 of securing member; Its two ends respectively are provided with a bolted with it pressing plate 2.The light source outside can be provided with dust cover 9, and dust cover can link to each other with securing member by bolt.Securing member comprises connector 17, cover plate 19, and they link to each other with bolt 18,20,21. Sequence number 7,8 is respectively connecting pipe, stop valve.
