Control part, described control part comprises the electromagnet that series connection arranges, power supply, fixed touching plate, movable contact spring, described electromagnet is used for controlling described inlet valve, and be provided with spring between described inlet valve and described electromagnet, described fixed touching plate is two and just connects respectively described power supply, negative pole, two described fixed touching plates are arranged on described guide pin bushing and can be by described connecting rod conductings, described movable contact spring is arranged on described connecting rod, and described movable contact spring is distribute from top to bottom multiple, the resistance of multiple described movable contact springs increase gradually and multiple described movable contact spring between mutually insulated, also mutually insulated between described connecting rod and multiple described movable contact spring.
As the improvement of technique scheme, described movable contact spring is tubular structure and is sheathed on described connecting rod.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
The gradual ball float induction system of one described in the utility model, by the consistent quantitation tube of upper and lower sectional area is set, make the electrolyte level variation of the liquid charging stock that is positioned at quantitation tube directly be scaled volume, can determine volume to the liquid charging stock realization of even density reinforced, thereby overcome the deficiency that the quantitatively inaccurate and equipment of weight needs periodic calibration, and device structure is simple, functional requirement for sensor is low, without the concrete buoyancy value of induction, only need observational measurement, therefore device fabrication cost is low, stable performance; In addition, due to the movable contact spring that is provided with multiple resistance and increases successively, make inlet valve can in quantitatively approaching terminal, close progressively inlet point, speed reinforced when quantitatively approaching terminal slows down, thereby be conducive to accurately quantitatively, can effectively prevent that material from adding excessive situation quantitatively time.
