Abstract
The utility model provides a liquid level controller for a water-sealing fire-retardant explosion-venting tank. The liquid level controller comprises three groups of liquid level tanks which are disposed in different positions on the same horizontal line. An adjusting screw rod is disposed in each liquid level tank. A reed switch proximity switch is installed below the adjusting screw rod. A magnetic float is also disposed in each liquid level tank. The reed switches of the three groups of liquid level tanks are disposed in positions of a normal liquid level, a liquid level upper limit and a liquid level lower limit. The liquid level overcomes a defect that a conventional liquidometer has a large error in indication, can realize accurate control of the liquid level or limiting of the liquid, and can also cooperate with a liquid level transmitter to convert a liquid level or limiting signal into a switching signal and utilize a 5-to-12VDC standard signal to realize remote-distance detection, indication, recording and control.
Description
Technical field
The utility model relates to automation field, specifically a kind of water-sealing fire-retardant venting of dust explosion bucket fluid level controller.
Background technology
At present, at oil, the industrial circles such as chemical industry, various container towers, tank, groove, the medium liquid level of the equipment such as spherical container and boiler detects, observe liquid level and mostly adopt magnetic flap level gauge, magnetic flap level gauge is also called magnetic float level indicator, it is to develop according to law of buoyancy and magnetic couplings effect, in the time of liquid level lifting in tested container, magnetic float in liquid level gauge body tube is lifting thereupon also, permanent-magnet steel in float is delivered to magnetic column indicator by magnetic coupling, drive red, white turned column upset, the red white intersection of indicator is the true altitude of internal tank liquid level, thereby realizing liquid level indicates clearly, but for the higher equipment of accuracy requirement, the liquid level index error of this liquid level gauge is larger, can not meet the control requirement of some high precision apparatus.
Utility model content
The purpose of this utility model is just to provide a kind of water-sealing fire-retardant venting of dust explosion bucket fluid level controller, can coordinate liquid level Alarming control switch, realizes the bound control of liquid level or position, boundary and reports to the police.
The utility model for the technical scheme that realizes above-mentioned object and adopt is: a kind of water-sealing fire-retardant venting of dust explosion bucket fluid level controller, it is characterized in that: comprise three groups of liquid level buckets, described three groups of liquid level buckets are arranged on respectively on equipment diverse location same level line, in described liquid level bucket, adjusting screw(rod) is set, described adjusting screw(rod) below is provided with tongue tube approach switch, in described liquid level bucket, is also provided with magnetic ball float; The described tongue tube approach switch of described three groups of liquid level buckets is arranged on respectively normal liquid level, the position of the liquid level upper limit and liquid level lower limit.
The beneficial effects of the utility model are: overcome the large defect of existing liquid level gauge index error, can realize the liquid level of liquid or spacing accurate control; The utility model can also be mixed fluid level transmitter and be converted liquid level, limit signal to switching signal, utilizes the standard signal of 5 ~ 12VDC realize remote detection, indication, record and control.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure 1, liquid level bucket (A, B, C); 2, adjusting screw(rod); 3, tongue tube approach switch; The tongue tube approach switch of 3B, liquid level bucket B; The tongue tube approach switch of 3C, liquid level bucket C; 4, magnetic ball float; 5, magnetic ballottement is answered center; 6, normal liquid level; 7, the liquid level upper limit; 8, liquid level lower limit.
Embodiment
A kind of water-sealing fire-retardant venting of dust explosion bucket fluid level controller, as shown in Figure 1, comprise three groups of liquid level buckets 1, be respectively liquid level bucket A, liquid level bucket B and liquid level bucket C, described three groups of liquid level buckets 1 are arranged on respectively on equipment diverse location same level line, the interior adjusting screw(rod) 2 that arranges of described liquid level bucket 1, described adjusting screw(rod) 2 belows are provided with tongue tube approach switch 3, in described liquid level bucket 1, are also provided with magnetic ball float 4.
Described liquid level bucket A, liquid level bucket B, the described tongue tube approach switch 3 of liquid level bucket C, 3B, 3C are arranged on respectively normal liquid level, the position of the liquid level upper limit and liquid level lower limit.
Described adjusting screw(rod) 2 can mechanical control magnetic ball float 4 position, in the time that liquid drives magnetic ball float 4 to approach tongue tube approach switch, can avoid magnetic ball float 4 to fluctuate up and down with liquid, affect the detection effect of tongue tube approach switch 3.
When actual use the utility model, liquid level bucket A controls the normal liquid level 6 of indication, in the time that liquid level arrives normal liquid level 6, magnetic ball float 4 approaches the position of tongue tube approach switch 3 with liquid, now, magnetic ball float 4 arrives the magnetic ballottement of tongue tube approach switch 3 and answers center 5, the closed output of tongue tube approach switch 3, and equipment shows that liquid level is normal; Liquid level bucket B controls the indication liquid level upper limit 7, in the time that liquid level arrives the liquid level upper limit 7, magnetic ball float in liquid level bucket B approaches the position of tongue tube approach switch 3B with liquid, now, magnetic ball float arrives the magnetic ballottement of tongue tube approach switch 3B and answers center, the closed output of tongue tube approach switch 3B, equipment shows that liquid level arrives the liquid level upper limit; Liquid level bucket C controls indication liquid level lower limit 8, in the time that liquid level arrives liquid level lower limit 8, magnetic ball float in liquid level bucket C approaches the position of tongue tube approach switch 3C with liquid, now, magnetic ball float arrives the magnetic ballottement of tongue tube approach switch 3C and answers center, the closed output of tongue tube approach switch 3C, equipment shows that liquid level arrives liquid level lower limit.
The utility model can also be mixed fluid level transmitter and be converted liquid level, limit signal to switching signal, utilizes the standard signal of 5 ~ 12VDC realize remote detection, indication, record and control.
