Abstract
The utility model relates to a level ball controller for an industrial boiler, which is characterized in that a projecting end is arranged on one side of a rocking frame adjacent to the main magnetic steel; the projecting end of a projecting zero-adjustment board, which is provided with a weight, is arranged in a low-level magnetic steel assembly; when the water level is low, the main magnetic steel and the low-level magnetic steel mutually generate the repulsive force to drive the counter-clockwise rotation of the low-level magnetic steel, to drive a mercury switch to send out appliance switch signals and to carry out water-level alarm. When the water level continues to drop to the flood stage, owning to the unchanged directions of the repulsive force of the main magnetic steel and the low-level magnetic steel, the mercury switch is still under the alarm condition to ensure the unchanged state of the low water alarm and the safety use of the boiler.
Description
The utility model relates to a kind of Industrial Boiler with ball float Water Level Control device, reports to the police and interlock protection especially for high water-level alarm, low water level warning, the flood stage of back yard industry steam boiler.
The principle of back yard industry steam boiler water-level alarm is a lot of at present, adopts magnetic control standard, electric pole type and inductance type principle usually.Magnet controlled is to utilize the ball float in the floating drum to float in water, rise synchronously and descend with the variation of water level, the main magnet steel that links to each other with ball float is also made same up and down moved further in guide rail, affact when the magnetic field force of this main magnet steel on the magnet steel of outside magnet steel assembly, because the repulsive interaction of magnetic force, when repulsion during greater than the gravity of weight, make the clockwise deflection of reel cage on the magnet steel assembly drive mercoid switch and send the signal of telecommunication, finish the water-level alarm action.When water level drops to main magnet steel and is lower than the magnet steel position that low water level reports to the police, the repulsion that two magnet steel produce is rotated counterclockwise low water level warning magnet steel, thereby the reel cage that makes the magnet steel assembly is under the weight power effect of repulsion and weight, deflect into a side of weight counterclockwise, mercoid switch deflection recovers former on off state simultaneously.The low water level alarm signal disappears, and enters flood stage and reports to the police.But, be low water level and flood stage coexisting state in fact at this moment, low water level is reported to the police and should do not disappeared, disappear otherwise can think by mistake reports to the police, water level has returned to ordinary water level, if at this moment the flood stage warning system is malfunctioning, with the accident that causes boiler water shortage to be burnt.
As long as the purpose of this utility model is that low water level is reported to the police will continue alarm signal when providing a kind of state below boiler water level is in low water level at the deficiencies in the prior art, its signal lasts till that directly water level is higher than till the low water level.
The purpose of this utility model is to realize like this, the nose of the convex zeroing plate in the low water level magnet steel assembly is installed in the side of reel cage near main magnet steel, weight is fixed on the nose of zeroing plate, when main magnet steel drops on the low side during in the low water level magnet steel with water level, two magnet steel produce repulsive force, under the effect of repulsive force, the counterclockwise deflection of reel cage that low water level is reported to the police, the drive mercoid switch sends the signal of telecommunication and carries out the low water level warning, when water level continues to descend because magnet steel repulsion direction is constant, owing to stopping means (G) ball float is no longer moved down again, thereby kept the low water level alarm condition constant.Also low water level magnet steel assembly and flood stage magnet steel assembly can be installed change place on the basis of existing technology mutually, also can be remained on water level when being in the following water level of low water level, the low water level alarm condition is constant.
Because reporting to the police, low water level adopted above-mentioned device, perhaps low water level is reported to the police, the flood stage warning device is installed according to above-mentioned position, guaranteed that all low water level continues to report to the police, avoided when water level is lower than low water level owing to the low water level accident that boiler water shortage that the misunderstanding that produced causes causes that disappears of reporting to the police, thereby guaranteed the security that boiler uses.
