COUTERMEASURE DEVICE FOR FORGETTING OF OPENING VALVE OF OPENING/CLOSING VALVE FOR CHECKING BRAKE IN ROLLING STOCK

摘要

PROBLEM TO BE SOLVED: To perform usual brake operation by a driver with a simple structure without trouble even if the open/close valve for checking operated of closing valve in checking the brake is forgotten to operate the opening valve after finishing of the checking operation in a rolling stock interposing the open/close valve for brake operation and the open/close valve for checking in series on the way of the air piping between a high pressure air supply source and an air brake.;SOLUTION: The open/close valve Vm for checking is constituted by a solenoid valve, and an operation case B having an operation surface f covered with an openable/closable door 1 is mounted to a vehicle body F. The case is provided with an open/close switch means SW having the openably/closably operable switch operation parts b1, b2 of the open/close valve Vm for checking on the operation surface f, a timer T having an arbitrarily settable time-set operation part Ta of checking operation time on the operation surface f, and a control device C forcibly opening the valve Vm when the door 1 is closed or the setting time of the timer T is elapsed in the closing state of the open/close valve Vm for checking.;COPYRIGHT: (C)2005,JPO&NCIPI
