Abstract
The utility model relates to a double color quartz tube type anti-explosion night vision level meter, which is composed of a meter body, a quartz tube, a press cover, an upper valve, a lower valve, a blowdown valve, a back cover which is composed of two pieces of fluorescent glasses, such as red, green and red, a cold-light plate, an optical fiber and an anti-explosion box which is used for loading light regulators. The utility model has the advantages of simple structure, novel design, reliable sealing and high safety. The utility model can monitor the liquid level of medium and low voltage storage tanks, liquids in the tank or vapor-liquid coexistent liquids all weather. The brightness of luminous sheets can be automatically regulated when the light is dim or at night, and the display of the level position is clear and the monitoring is exactly.
Description
The utility model relates to a kind of explosion-proof night vision liquid level gauge of double-colored quartz tube type to having vapour phase and liquid phase to monitor in reservoir, the jar.
Adopt the quartz ampoule double colored indicator mostly in oil, chemical field monitoring liquid level at present, it includes table body, quartz ampoule, filler, gland, upper and lower valve, blowoff valve.Dress quartz ampoule in the table body, by filler, gland packing, the endoporus corner angle of quartz ampoule are over against inspection surface, and inspection surface is equipped with rule, and the table body is connected with upper and lower valve and blowoff valve by pressure pipe, adapter.This liquid level gauge utilizes refraction, the principle of reflection of light, can clearly monitor the liquid level that vapour is red, liquid is green.This liquid level gauge can only be by day or light use when strong, when light darkness or night, can not use.
The purpose of this utility model is at the existing problem of above-mentioned quartz ampoule double colored indicator, aims to provide the round-the-clock explosion-proof night vision liquid level gauge of double-colored quartz tube type that liquid level is monitored of a kind of energy.
The implementation of the utility model purpose is that the explosion-proof night vision liquid level gauge of double-colored quartz tube type includes table body, quartz ampoule, gland, goes up valve, lower valve, blowoff valve.Dress quartz ampoule 4 in the table body 3 is by filler, gland 5 sealings.The endoporus corner angle of quartz ampoule are over against inspection surface, and inspection surface is equipped with rule.The table body is connected with last valve 1, lower valve 8 and blowoff valve 9 by pressure pipe 6, adapter.Table has back cover 10 behind the body, and back cover is made of the light tiles 11 of dress in the middle of red, green, a red trichromatism fluorescent glass plate 13, white glass plate 11 and two glass plates.There is front protection cover 15 table body front, and there is the armored cassette 2 of dress light regulator back, side, and the light regulator links to each other with the table body.
The light regulator is made of light-operated circuit, booster circuit, cold light source electroluminescence lamp sheet, and the 12V electricity is through ic chip
2(7805) give ic chip after the voltage stabilizing
2(NE555) power supply, IC
2To the relay J power supply, master control constitutes booster circuit by pulse transformer T and triode.
The utility model is described in detail in detail with reference to the accompanying drawings
Fig. 1 the utility model structural representation
Fig. 2 table body portion structural representation
Fig. 3 light regulator electrical schematic diagram
With reference to Fig. 1,2, the utility model is pressed Q/HYGS.N12.02.066---2000 " liquid level gauge " standard production, different is to adorn light tiles 12 in the middle of having increased back cover 10, two glass plates that are made of two blocks of three fluorescence glass sheet, and the table body is connected with the light regulator.
When the utility model is installed, the joint flange and the reservoir of upper and lower valve 1,8, the service pipe of jar are connected.The utility model is according to linker and optical transmission, refraction principle, demonstrates under vapour, liquid coexistence situation that vapour is red, liquid is green.Rule is embedded with white glass sheet 14, and its effect is to prevent dust, be incubated.Back cover 10 is embedded with white glass sheet 11, light tiles 12, three fluorescence glass plate 13.
With reference to Fig. 3,, the utility model can be monitored round-the-clockly to liquid level owing to the light regulator that links to each other with light tiles 12 is housed at the table body side surface.The principle of work of light regulator is as follows: by day with light when strong, the liquid level clear display of liquid level gauge, liquid level gauge need not the light source compensation, and the 12V electricity is through ic chip
1(7805) IC is given in voltage stabilizing
2(NE555) power supply, IC
2Connect trigger, because the photoresistance in the trigger is subjected to illumination, resistance reduces, IC
2Output low level, not adhesive of relay J, its normally opened contact is not closed, booster circuit is not powered, thereby do not work.
When light during dark or night, IC
2The output high level, the relay J adhesive, booster circuit gets electric, vibration power transformation device C
4Work, output 50V, 800HZ pulse voltage, driven for emitting lights plate 12 is luminous, to demonstrate liquid level.The luminous environment of light tiles can be according to W
1Regulate.
The utility model is simple in structure, modern design, and sealing is reliable, and is safe in utilization, flame-proof type d II BT6.The utility model can right＜6.4MPa in, the low pressure storage device, the liquid level of the liquid of pot liquid or vapour-liquid coexistence carries out monitoring round-the-clockly, can be luminous automatically when light darkness or night, make position, boundary clear display, monitoring accurately.
