Abstract

EN UNA DIRECCION DE SEGURIDAD PARA PRENSA HIDRAULICA, DONDE UN UNA CONDUCCION DEL MEDIO DE PRESION, QUE ESTA CERRADO SOBRE UN ESPACIO DEL MEDIO DE PRESION EN UNA UNIDAD DE EMBOLO-CILINDRICO, HAY DISPUESTAS DOS VALVULAS CONECTABLES EN CONEXION EN SERIE, CUYA POSICION DE CIERRE ES CONTROLABLE SEPARADAMENTE, DONDE LA DIRECCION DE LA SEGURIDAD ES INFLUIBLE EN DEPENDENCIA DEL RESULTADO DEL CONTROL. AQUI HAY QUE VIGILAR EL CIERRE IMPERMEABLE DE LA VALVULA. A LA CONEXION EN SERIE DE AMBAS VALVULAS (4,5) HAY CONECTADA PARALELAMENTE UNA UNIDAD DE CONTROL A PRESION (7), QUE ESTA CERRADA SOBRE LA CONDUCCION DEL MEDIO DE PRESION (11) EN EL SENTIDO DEL ARRASTRE POR CORRIENTE DE LA PRIMERA VALVULA (4) A TRAVES DE UNA CONEXION DE PRESION MEDIANA (3) Y DESPUES DE LA SEGUNDA VALVULA (5) A TRAVES DE UNA CONEXION DE PRESION BAJA (1). EN LA UNIDAD DEL CONTROL DE PRESION (7) HAY CONECTADO PARA AMBAS VALVULAS (4,5) UN PULSADOR DE DIFERENCIA ESPECIAL (D1,D2) Y PARA AMBOS PULSADORES DE DIFERENCIA (D1,D2) UNA VALVULA REGULADORA DE PRESION (8) AJUSTABLE CON LA POSICION DE EFICACIA DE UNA AMPLIACION DE LA PRESION DE MEDIOS Y UNA PROFUNDIDAD DE LA PRESION DE MEDIOS EN LA PRESION BAJA.IN A SAFETY DIRECTION FOR HYDRAULIC PRESS, WHERE A MEDIUM PRESSURE CONDUCTION, WHICH IS CLOSED OVER A SPACE OF THE PRESSURE MEDIUM, IN A SERIAL CONNECTION VALVES, TWO POSITIONS OF SERIAL CONNECTION IT IS SEPARATELY CONTROLLABLE, WHERE SAFETY MANAGEMENT IS INFLUIBLE DEPENDING ON THE CONTROL RESULT. HERE YOU HAVE TO WATCH THE WATERPROOF CLOSURE OF THE VALVE. A PRESSURE CONTROL UNIT (7) IS PARALLELY CONNECTED TO THE SERIAL CONNECTION OF BOTH VALVES (4,5), WHICH IS CLOSED ON THE CONDUCTION OF THE PRESSURE MEDIUM (11) IN THE DIRECTION OF DRAGAGE BY CURRENT OF THE FIRST VALVE (4) THROUGH A MEDIUM PRESSURE CONNECTION (3) AND AFTER THE SECOND VALVE (5) THROUGH A LOW PRESSURE CONNECTION (1). IN THE PRESSURE CONTROL UNIT (7) A SPECIAL DIFFERENCE BUTTON (D1, D2) IS CONNECTED FOR BOTH VALVES (4,5) AND FOR AN ADJUSTABLE PRESSURE REGULATING VALVE (D1, D2) WITH THE POSITION OF EFFICIENCY OF AN EXTENSION OF THE PRESSURE OF MEDIA AND A DEPTH OF THE PRESSURE OF MEDIA IN THE LOW PRESSURE.
