Hydraulic control valve system and loading machine
The invention relates to the technical field of hydraulic control systems, in particular to a hydraulic control valve system and a loader.The hydraulic control valve system comprises a variable displacement piston pump body, a constant displacement pump body and a valve body device, the variable displacement piston pump body and the constant displacement pump body are communicated with the valve body device, and the valve body device is communicated with an oil tank; the valve body device comprises a control valve assembly, an overflow valve assembly, a working valve assembly and a connecting pipeline assembly, the connecting pipeline assembly is provided with a first inlet and a second inlet, the first inlet is communicated with the variable displacement piston pump body, the second inlet is communicated with the constant displacement pump body, and the overflow valve assembly is communicated with the working valve assembly. The control valve assembly, the overflow valve assembly and the working valve assembly are communicated through the connecting pipeline assembly, in the structure, the control valve assembly, the overflow valve assembly and the working valve assembly are integrated on one valve body, double-pump confluence of a constant and variable system is achieved, the needed installation space is small, and cost is lower.
本发明涉及液压控制系统技术领域，特别涉及一种液压控制阀系统及装载机，包括：变量柱塞泵本体、定量泵本体和阀体装置，所述变量柱塞泵本体、所述定量泵本体分别与所述阀体装置连通，所述阀体装置与油箱连通，所述阀体装置包括控制阀组件、溢流阀组件、工作阀组件以及连接管路组件，所述连接管路组件具有第一入口与第二入口，其中所述第一入口与所述变量柱塞泵本体连通，所述第二入口与所述定量泵本体连通，所述控制阀组件、所述溢流阀组件和所述工作阀组件通过所述连接管路组件连通，在上述的结构中，本申请将控制阀组件、溢流阀组件、工作阀组件集成在一块阀体上，实现定变量系统双泵合流，且所需安装空间小并且成本更低。
