Abstract
The utility model relates to the technical field of control valves, and particularly relates to a novel middle digging precursor control valve group. The novel middle digging precursor control valve group is characterized by comprising an oil way pipe, a power supply device, a control switch, an oil cylinder, a first control valve, a second control valve and a third control valve, wherein the oil way pipe is provided with the three control valves, namely the first control valve, the second control valve and the third control valve; and the control switch of the power supply device controls the first control valve, the second control valve and the third control valve. More than two continuous digging actions of a digging machine are realized, the defect of single action existed in digging machine with the traditional structure is changed, and the hydraulic flow demand required by equipment can be met.
Description
Technical field
The present invention relates to the control valve technical field, especially a kind ofly dig the pilot-actuated valve group in novel.
Background technique
Dig the pilot-actuated valve group at present in the tradition and form, in the digging machine, can not solve two digging machine actions in this being connected by two control power supplys.
Summary of the invention
For addressing the above problem; The invention provides and a kind ofly dig the pilot-actuated valve group in novel, saidly a kind ofly dig the pilot-actuated valve group in novel, it is characterized in that; Comprise: oil circuit pipe 1, power supply device 2, control switch 3, oil cylinder 4, first control valve 5, second control valve 6, the 3rd control valve 7; Saidly a kind ofly dig the pilot-actuated valve group in novel, on oil circuit pipe 1, be provided with three control valves, be i.e. first control valve 5, second control valve 6 and the 3rd control valve 7; Control switch 3 commanders first control valve 5 through power supply device 2, second control valve 6, the 3rd control valve 7; Realize the plural continuous digging machine action of digging machine, changed conventional construction digging machine action monotony, the needed hydraulic flow demand of the equipment that reaches.
Beneficial effect of the present invention: simple to operate, efficiency of assembling is high, and assembly precision is high.
Description of drawings
Fig. 1 is a structural drawing of the present invention;
Wherein: oil circuit pipe 1, power supply device 2, control switch 3, oil cylinder 4, first control valve 5, second control valve 6, the 3rd control valve 7.
Embodiment
As shown in the figure; Saidly a kind ofly dig the pilot-actuated valve group in novel, on oil circuit pipe 1, be provided with three control valves, be i.e. first control valve 5, second control valve 6 and the 3rd control valve 7; Control switch 3 commanders first control valve 5 through power supply device 2, second control valve 6, the 3rd control valve 7; Realize the plural continuous digging machine action of digging machine, changed conventional construction digging machine action monotony, the needed hydraulic flow demand of the equipment that reaches.
