| description | The utility model discloses a liquid filling system for linkage hydraulic machine in linkage hydraulic machine field. The liquid filling system includes a liquid supply electro magnetic valve and a liquid filling valve correspondingly controlling oil in and out of the main oil cylinder of each pressing machine. Each liquid filling valve and the main oil cylinder of corresponding hydraulic machine is serially connected and then parallelly connected between the outlet of the liquid supply electro magnetic valve and an oil return pipe. Each liquid filling valve includes a valve in which a valve core and a piston are positioned. When the piston moves upwards, the opening of the valve core gradually increases. The upper end of the piston is provided with a valve plate; a limit switch is fixed to the valve plate; a top bar is fixed to the upper end of the piston; the top bar extends upwards out of the valve plate; the top bar goes against a triggering bar of the limit switch; each limit switch and an electro magnet |
