The mechanical control type multi-way valve comprises a portal frame lifting control valve, the lower position of the portal frame lifting control valve is connected with a first logic valve assembly, the first logic valve assembly comprises a first oil way, and a first one-way valve is arranged on the first oil way; the second oil way comprises a first control oil way and a second control oil way, a logic valve and a manual valve for controlling the logic valve to act are arranged on the first control oil way, and the second control oil way is connected with the logic valve and the portal frame lifting control valve; the first oil way and the second oil way are connected to the portal frame lifting control valve in parallel. The portal frame lifting control valve is used for controlling the lifting action of the portal frame, the first logic valve assembly controls the oil way circulation condition of the portal frame lifting control valve through different logic relations, so that the lifting action of the portal frame is controlled, and the problem that a manual operation type multi-way valve is matched with the OPS function is solved through the scheme.
本发明公开了一种叉车的机械操纵型多路阀,包括门架起升控制阀,所述门架起升控制阀的下位连接第一逻辑阀组件,所述第一逻辑阀组件包括第一油路,所述第一油路上设有第一单向阀;第二油路,包括第一控制油路和第二控制油路,所述第一控制油路上设有逻辑阀和控制逻辑阀动作的手动阀,所述第二控制油路连接所述逻辑阀和所述门架起升控制阀;所述第一油路和第二油路并联于所述门架起升控制阀。门架起升控制阀用于控制门架的升降动作,第一逻辑阀组件通过不同的逻辑关系控制门架起升控制阀的油路流通情况,从而控制门架的升降动作,该方案解决了手动操作型多路阀匹配OPS功能的问题。
