Problems solved by technology

[0002] At present, the multi-way valve control system of many hydraulic truck cranes in China uses the control valves to form a control valve group through pipeline connection, resulting in a large volume of the control system, difficult installation and maintenance, and a low degree of automation. Although a few domestic hydraulic truck cranes and On foreign hydraulic truck cranes, the boarding combination control valve also adopts an integrated method to combine the control valves together, but the structure is complicated, the volume is large, and the price is expensive.

Abstract

The invention discloses an electrically-controlled multifunctional compact type control valve assembly, which comprises a valve body, of which the right part is provided with an oil supply system and the left part is provided with a control system; the valve body is provided with five input ports; the oil supply system is provided with five output control ports which are correspondingly communicated with the five input ports; the valve body is provided with nine working ports which are matched with the input ports by an electromagnetic valve, a one-way valve and an inner runner of the valve body; the electricity-liquid integration structural design is adopted; by the assembly of the valve body and oil paths in the valve body, the electromagnetic valve and all hydraulic elements are highly integrated, the original complicated control route is simplified; moreover, the valve assembly also has the advantages of small volume, short runner, simple structure, high degree of automation, wide application range and convenient assembly and maintenance.

Description

technical field [0001] The invention relates to the technical field of hydraulic valves, in particular to an electronically controlled multifunctional compact control valve group. Background technique [0002] At present, the multi-way valve control system of many hydraulic truck cranes in China uses the control valves to form a control valve group through pipeline connection, resulting in a large volume of the control system, difficult installation and maintenance, and a low degree of automation. Although a few domestic hydraulic truck cranes and On foreign hydraulic truck cranes, the boarding combination control valve also adopts an integrated method to combine the control valves together, but the structure is complicated, the volume is huge, and the price is expensive. Such as the Chinese invention patent "electrically controlled multifunctional compact control valve group" (notification number CN2859044Y) whose patent number is ZL200520034867.5 is exactly this type of de...
