GRIFO CON ACCIONADOR CUYA APTITUD PARA EL FUNCIONAMIENTO PUEDE SER CONTROLADA

LA INVENCION SE REFIERE A LAS LLAVES CON ACTUADOR ALIMENTADO POR UNA FUENTE DE ENERGIA NEUMATICA O ELECTRICA. LA INVENCION PREVE UN SENSOR (13) DE MEDIDA DE LA POTENCIA EXIGIDA A LA FUENTE DE ENERGIA Y UN CIRCUITO ELECTRONICO (11) CONECTADO AL SENSOR (13) Y A MEDIOS (10) QUE DETECTAN QUE EL ACTUADOR ACCIONA LA LLAVE A FIN DE COMPARAR, CUANDO EL ACTUADOR ACCIONA LA LLAVE, LA POTENCIA CONSUMIDA CON UN VALOR DE CONSIGNA Y EMITIR UNA INSTRUCCION EN FUNCION DE LA COMPARACION. The tap is actuated by an energy source and comprises sensors (13,31) to detect that the actuator operates the tap. A first sensor measures a magnitude representing the power consumed from the energy source. An electronic circuit (11,29) is connected to the first sensor and to a comparator (10,28) which, when the actuator operates the tap, compares the magnitude representing the power consumed from the energy source with a set value, and emits an instruction as a function of this comparison. In the case of a pneumatic energy source a pressurised fluid is used. The actuator has a pneumatic valve piston (5) and the first sensor (13) measures the fluid pressure on either side of the piston (5). In the case where an electrical current energy source is used. the actuator is an electro-mechanical transducer (23) and the first sensor (31) measures the electrical power consumed from the energy source at the time the tap is operated.
