HYDRAULIC OPERATING VALVE FOR WORKING MACHINE
In accordance with the present invention, provided is a hydraulic control valve for a working machine. In accordance with the present invention, the hydraulic control valve for a working machine includes: a first control valve formed to supply oil to at least one driving cylinder provided in a working machine mounted on a working vehicle, thereby operating the driving cylinder; and a second control valve separably connected to the first control valve, and formed to be connected to the first control valve and supply oil to at least one separate driving cylinder provided in an attachment when the attachment is mounted on the working vehicle, thereby operating the at least one driving cylinder. The first control valve includes a connection flow path connected to a supply flow path and a discharge flow path of the first control valve and a supply flow path and a discharge flow path of the second control valve, and to which a third control valve is connected. The connection flow path includes: a first connection flow path in which a first closure plug disconnecting the supply flow path of the first control valve from the discharge flow path and connecting the supply flow path to the connection flow path is placed, a second closure plug disconnecting the supply flow path of the first control valve from the discharge flow path and connecting the supply flow path to the supply flow path of the second control valve is detachably placed, the first closure plug is placed at one end connected to the discharge flow path of the first control valve, and a C port connected to the third control valve is formed at the other end; a second connection flow path of which one end is connected to the supply flow path of the first control valve and the other end is extended to the outer surface of the first control valve to be connected to the supply flow path of the second control valve, and in which the second closure plug is placed; and a third connection flow path which is connected to a part in which the discharge flow path of the second control valve and the first and second connection flow paths intersect with each other. Therefore, the present invention is capable of rationally implementing oil supply.
