摘要： A multi-way valve includes a plurality of parallel combination valves for controlling corresponding actuators (4-1-4-5). Each combination valve comprises proportional throttle valves (2-1-2-5) and reversing valves (3-1-3-5). An oil inlet of the proportional throttle valve is communicated with a main oil inlet (P), and an oil outlet of the proportional throttle valve is communicated with an oil inlet of the reversing valve. An oil outlet of the reversing valve is communicated with the main oil return port (T). Wherein, each combination valve further comprises a one-way control valve (9-1-9-5, 10-1-10-5) for obtaining the load pressure of corresponding actuator. One side of the one-way control valve is communicated with a pipeline between the proportional throttle valve and the actuator. The multi-way valve further includes a control element (8) which receives the load pressure fed back by each one-way control valve and responds to the load pressure to control the supply of hydraulic oil for the actuators. The multi-way valve has the load-sensitive function, thereby reducing energy loss and system heat productivity. A hydraulic equipment and a concrete pump vehicle corresponding to the multi-way valve are also provided.
