Fluid valve, fluid system, construction machine, and control method
The invention provides a fluid valve, a fluid system, a construction machine, and a control method. An independent regulating valve (2) is provided with a valve body (3) and an outlet regulating spool (15). The valve body (3) has: discharge ports (D1), (D2) connected to any of ports (Rp), (Hp) provided to a hydraulic cylinder (113) driven by hydraulic oil; and tank ports (T1), (T2) that are connected to discharge flow paths (135), (136). The outlet adjustment spool (15) causes the rod port (Rp) to communicate only with the cap port (Hp), or causes the rod port (Rp) to communicate only with the (2)-th tank port (T2), or causes the rod port (Rp) to communicate with both the cap port (Hp) and the (2)-th tank port (T2).
本发明提供一种流体阀、流体系统、施工机械以及控制方法。本发明的独立调节阀(2)具备阀体(3)和出口调节滑阀芯(15)。阀体(3)具有：各排出端口(D1)、(D2)，其与设置到由工作油驱动的液压缸(113)的各端口(Rp)、(Hp)中任一个连接；和各罐端口(T1)、(T2)，其与各排出流路(135)、(136)连接。出口调节滑阀芯(15)使杆端口(Rp)仅与盖端口(Hp)相通，或使杆端口(Rp)仅与第(2)罐端口(T2)相通，或使杆端口(Rp)与盖端口(Hp)和第(2)罐端口(T2)这两者相通。
