The invention discloses an air control hydraulic reversing valve achieving double-way different pressures and flows and mainly relates to the technical field of hydraulic system control. The air control hydraulic reversing valve comprises a valve body (1), an elevating valve rod (6), a reversing valve rod (9), a reversing air cylinder (12) and a hoisting air cylinder (18). By means of the composite valve, a pressure oil source of one inlet valve can be used and converted into two hydraulic systems with two different pressures and different flows, namely, one hydraulic oil pump can be used in cooperation with the valve, and two sets of hydraulic systems composed of two oil pumps or one double pump and two hydraulic reversing valves can be replaced.
本发明公开了双路不同压力及流量的气控液压换向阀,主要涉及液压系统控制技术领域,包括阀体(1)、举升阀杆(6)、换向阀杆(9)、换向气缸(12)、举升气缸(18),该复合阀的发明,它可用一个进阀的压力油源转换成为两种不同压力及不同流量的两个液压系统,即可用一台液压油泵和该阀配合使用,可取代两台油泵(或一台双联泵)和两台液压换向阀组成的两套液压系统。
