Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.
Shown in Fig. 1-4, a kind of for fire cistern automatic feeding water control device, comprise the fire cistern 1 and relay indicating light with water inlet pipe 2, level sensor is provided with in fire cistern 1, level sensor comprises high water level sensor 4 and low water level sensor 5, water inlet pipe 2 is provided with electromagnetic valve 3, and the input of electromagnetic valve 3 is provided with electronic controller 6, and electronic controller 6 opens or closes water inlet pipe 2 by the feedback signal Controlling solenoid valve 3 of level sensor; Electronic controller 6 comprises triode, relay, rectifier bridge stack, transformer and electric capacity, triode comprises the first triode and the second triode, relay is driven by the cooperation of the first triode and the second triode, and transformer is converted the AC12V come and is rectified into DC12V supplied for electronic controller 6 and works by rectifier bridge stack; Also comprise diode in electronic controller 6, diode is speed stream diode; The model of the first triode and the second triode is C2060; Level sensor is common throw-in type liquid level sensor; Electromagnetic valve 3 is water copper body electromagnetic valve.
Whole system is made up of three parts, and Part I is the signal collection of level sensor; Part II is the process that electronic controller 6 carries out signal; Part III be electromagnetic valve 3 as executing agency, this three part constitutes the input of signal, process and performs flow process, and whole system completes fire cistern automatic feeding water with the form of closed-loop control, maintains the constant of fire cistern water level.During plant running, the power supply of alternating current 220V is converted to AC12V by transformer pressure-reducing, then be transformed into DC12V for electronic controller 6 by rectifier bridge stack and DC supply is provided, filter capacitor is arranged in rectification circuit, the direct current be used for containing ripple and ripple component after smooth commutation, for circuit provides a stable working power.
When fire cistern 1 is in low water stage state, A point is low level, first triode cut-off, its current collection very high level, due to the current collection very high level of the first triode, that is the base stage of the second triode is high level, and such second triode is saturated rapidly and drive relay, perform water inlet operation, relay indicating light is lit simultaneously; When the water level of fire cistern 1 is in high water level state, A point is high level, first triode ON, its current collection very low level, second triode becomes cut-off state from saturation state, relay no-output, and electromagnetic valve 3 current supply circuit is also because the disconnection of relay contact quits work, relay indicating light also power-off extinguishes, and fire cistern 1 also stops water inlet; The work that whole system is gone round and begun again just maintains the constant level of fire cistern 1, reaches the object of automatic feeding water, and system availability is stable, long service life.
