The invention relates to the technical field of control valves, in particular to a novel internal-energy digging pilot control valve unit. The novel internal-energy digging pilot control valve unit is characterized by comprising an oil cylinder, a valve manifold block, an oil tube control switch, an internal energy tank and power supply devices; the internal energy tank is arranged on the valve manifold block and supplies required energy to the digging pilot control valve unit through the oil tube control switch, and internal energy required by an excavator for long-time operating is realized.
Description
technical field [0001] The invention relates to the technical field of control valves, in particular to a novel internal energy mid-digging pilot control valve group. Background technique [0002] At present, the traditional mid-excavation pilot control valve group is composed of two control power sources. This connection cannot provide the internal energy required for long-term work of the excavator. Contents of the invention [0003] In order to solve the above problems, the present invention provides a new type of internal energy mid-cut pilot control valve group. The novel type of internal energy mid-cut pilot control valve group is characterized in that it includes: oil cylinder 1, valve manifold 2, oil Road pipe control switch 3, internal energy tank 4, power supply 5, the new type of internal energy mid-piercing pilot control valve group, an internal energy tank 4 is provided on the valve manifold 2, and the internal energy tank 4 passes through the oil The road pi...
