Multi-way valve for loading machine, loading machine hydraulic system and loading machine
The invention discloses a multi-way valve for a loading machine, a hydraulic system of the loading machine and the loading machine. The oil inlet P and the oil return port T are formed in the valve body; the first valve element is arranged in the valve body and used for controlling the bucket oil cylinder to act through the working oil port A1 and the working oil port B1, and pilot oil from the pilot valve drives the first valve element to reverse through the pilot oil port a1 and the pilot oil port b1; the second valve element is arranged in the valve body and used for controlling the movable arm oil cylinder to act through a working oil port A2 and a working oil port B2, and pilot oil from the pilot valve drives the second valve element to reverse through a pilot oil port a2 and a pilot oil port b2; in the reversing process of the first valve element and the second valve element, hydraulic oil flows through all the valve ports set according to the set valve port matching rule. The control characteristic of each action of the loader can be effectively improved, the impact of the whole loader is reduced, the operation feeling of a driver is improved, and the fatigue strength of the driver is reduced.
本发明公开了一种装载机用多路阀、装载机液压系统及装载机，多路阀包括：阀体；设置在阀体上的进油口P、回油口T；设置在阀体内，用于通过工作油口A1、工作油口B1控制铲斗油缸动作的第一阀芯，来自先导阀的先导油通过先导油口a1、先导油口b1驱动第一阀芯换向；设置在阀体内，用于通过工作油口A2、工作油口B2控制动臂油缸动作的第二阀芯，来自先导阀的先导油通过先导油口a2、先导油口b2驱动第二阀芯换向；在第一阀芯、第二阀芯的换向过程中，液压油流经按照设定的阀口匹配规则设定的各阀口。本发明能有效提高装载机各动作的控制特性，减小了整机冲击，提升了驾驶员的操作感受，降低了驾驶员的疲劳强度。
