Abstract
A multi-station hydraulic control valve comprises a valve body. At least four oil pipe joints are arranged on the valve body. At least one W-shaped oil pipe joint among the four oil pipe joints is connected with a time delay valve. The oil pipe joints are mutually communicated through internal oil ducts in the valve body. At least six working oil ports which are respectively communicated with the internal oil ducts are further arranged on the valve body. At least three shuttle valves which can move and can open and close the internal oil ducts are arranged in the internal oil ducts in the valve body. The multi-station hydraulic control valve can enable a working machine to carry out single output in multiple channels in the working process, and enables the multiple channels to be self-locked mutually. Simultaneously, the output channel is communicated with the time delay valve. Since the time delay valve enables the working pressure to be slowly increased, pressure impact is decreased. Consequently, the multi-station hydraulic control valve achieves the purpose of stable working and prolongs the service life of the working machine.
