Abstract
The utility model discloses a nitrogen valve valve blow -by automated inspection alarm device at bottom of converter, its aim at provide one kind can in time detect nitrogen gas valve leakage detecting device to the nitrogen valve valve blow -by automated inspection alarm device at bottom of converter that can in time report to the police, the device is including parallelly connected first pipe and second pipe, first pipe with establish ties with bottom blowing gas pipeline again after the second pipe is parallelly connected and blow to the converter, first pipe expert has nitrogen gas, first pipe with have first trip valve and second trip valve on the second pipe respectively, select carrier gas through rotating of first trip valve and second trip valve, on first pipe in proper order the series connection have first trip valve and the third trip valve, first trip valve with first union coupling nitrogen gas delivery pipe between the third trip valve, ann has nitrogen gas trip valve and manometer on the nitrogen gas delivery pipe, the manometer is connected with alarm devices.
Description
Technical field
The utility model relates to converter steeling technology field, particularly nitrogen valve valve blow-by automatic detection alarm device at the bottom of a kind of converter.
Background technology
In order to reduce argon gas cost consumption, converter current bottom blown gas adopts nitrogen argon to switch master mode, and bessemerize process mid-early stage employing nitrogen as bottom blown gas, the later stage adopts argon gas as bottom blown gas.Nitrogen is objectionable constituent for the emphasis variety steel of steel-making as auto sheet, pipe line steel, needs to reduce nitrogen in steel content.
Current nitrogen ar system shifter is blown to converter with bottom blown gas placed in series after adopting nitrogen transfer lime in parallel with argon delivery lines again, and nitrogen transfer lime and argon delivery lines have trip valve respectively, switches selection delivering gas by trip valve.But in actually operating, if nitrogen trip valve is not closed tight during conveying argon gas, nitrogen will be blown into molten steel by pipeline, affect steel quality, and whether nitrogen trip valve is closed tight and is not easy discovery, is difficult to timely disposal.
Summary of the invention
The technical problems to be solved in the utility model is, provides one can detect nitrogen valve valve blow-by proofing unit in time, and can and alarm converter at the bottom of nitrogen valve valve blow-by automatic detection alarm device.
For reaching above-mentioned purpose, nitrogen valve valve blow-by automatic detection alarm device at the bottom of a kind of converter of the utility model, described device comprises: the first pipe in parallel is managed with second, blow to converter with bottom blown gas placed in series again after described first pipe is in parallel with described second pipe, described first pipe is connected with nitrogen, described first pipe and described second pipe there are the first trip valve and the second trip valve respectively, selection delivering gas is switched by the first trip valve and the second trip valve, first pipe is in series with the first trip valve and the 3rd trip valve successively, the first pipe between described first trip valve and described 3rd trip valve connects nitrogen discharge pipe, described nitrogen discharge pipe is equipped with nitrogen trip valve and tensimeter, described tensimeter is connected with panalarm.
Wherein said manometric benchmark value is 0.3Mpa.
Wherein said tensimeter is digital pressure gauge.
At the bottom of the utility model converter, nitrogen valve valve blow-by automatic detection alarm device difference from prior art is that the utility model achieves following technique effect:
The utility model, by the design of tensimeter and panalarm, provides one can detect nitrogen valve valve blow-by proofing unit in time mutually, and can and alarm.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of nitrogen valve valve blow-by automatic detection alarm device at the bottom of the utility model converter.
Embodiment
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.
As shown in Figure 1, nitrogen valve valve blow-by automatic detection alarm device at the bottom of a kind of converter of the utility model, described device comprises: the first pipe 1 and the second pipe 2 in parallel, described first pipe 1 is blown with connecting to converter with bottom blown gas pipeline 3 after described second pipe 2 parallel connection again, described first pipe 1 is connected with nitrogen, described first pipe 1 and described second pipe 2 there is the first trip valve 4 and the second trip valve 5 respectively, selection delivering gas is switched by the first trip valve 4 and the second trip valve 5, first pipe 1 is in series with the first trip valve 4 and described 3rd trip valve 6 successively, the first pipe 1 between described first trip valve 4 and described 3rd trip valve 6 connects nitrogen discharge pipe 8, described nitrogen discharge pipe 8 is equipped with nitrogen trip valve 9 and tensimeter 10.
Preferably, described tensimeter 10 is connected with panalarm 11, because be connected to panalarm 11, avoid manually monitoring tensimeter for a long time, saves labor force.Managerial personnel's Timeliness coverage valve is leaked gas, avoids danger.When tensimeter is greater than benchmark value formula, report to the police; Do not respond lower than benchmark value panalarm.
When providing nitrogen to converter, then the second trip valve 5 cuts out, and nitrogen trip valve 9 cuts out, and the first trip valve 4 and the 3rd trip valve 6 are opened, and when providing argon gas to converter, the second trip valve 5, nitrogen trip valve 9 is opened, and the first trip valve 4 and the 3rd trip valve 6 are closed.When the 3rd trip valve 6 has leakage, nitrogen enters described tensimeter 10 by nitrogen trip valve 9, and tensimeter 10 controls panalarm 11 and reports to the police after having pressure, staff handles it, and plays the effect automatically detecting and report to the police.
Preferably, described manometric benchmark value is 0.3Mpa, shows that above-mentioned numerical value is applicable to majority of case through Comprehensive Experiment, certain particular case we specifically to adjust benchmark value.
Preferably, described tensimeter is digital pressure gauge, and digital pressure gauge is more directly perceived, also more accurate, and we can be visual to data, is convenient to watchstander and copies related data.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
