The working valve block comprises a valve body, the valve body is provided with an oil inlet channel, a working channel and an energy storage channel, the oil inlet channel is used for being communicated with a liquid pump of the forklift, the working channel is used for being communicated with an action mechanism of the forklift, and the energy storage channel is used for being communicated with an energy storage device of the forklift. When the working channel communicates with the energy storage channel, pressure oil can enter the working channel from the oil inlet channel, and when the working channel communicates with the energy storage channel, the pressure oil can enter the energy storage channel from the working channel so that kinetic energy of the pressure oil can be stored in an energy storage device of the forklift. According to the working valve block and the forklift provided by the invention, the problem that an existing forklift portal frame loses too much energy in the descending process is solved.

    本申请涉及工作阀块及叉车,工作阀块包括阀体,阀体设有进油通道、工作通道和储能通道,进油通道用于连通叉车的液泵,工作通道用于连通叉车的动作机构,储能通道用于连通叉车的储能装置,当工作通道连通进油通道时,压力油液能够从进油通道进入工作通道,当工作通道连通储能通道时,压力油液能够从工作通道进入储能通道,以将压力油液的动能储存于叉车的储能装置内。本申请提供的工作阀块及叉车,解决了现有的叉车门架在下降过程中损失能量过大的问题。
