Problems solved by technology

[0002] As one of the key components of the excavator hydraulic system, the multi-way control valve requires the advantages of high working pressure, compact structure, small pressure loss, and easy installation and operation. Currently, the integral multi-way valve used on the excavator has a valve core Disadvantages such as complex structure, complex casting of valve body flow channel, large pressure loss of inlet and outlet oil, and most of the pilot control methods are hydraulic control, there are problems such as many pilot lines, poor control flexibility, and unsatisfactory energy-saving effect

Abstract

The invention relates to a medium-sized excavator electric control multi-way valve which comprises a right valve body, a left valve body, a first main oil way and a second main oil way, and valve element assemblies contained in the right valve body are an unloading unit, a left walking unit, a rotation unit, a movable arm regeneration unit, a bucket rod regeneration unit and a standby unit in sequence. The left valve body comprises valve core components which are a linear walking link, a right walking link, a movable arm link, a bucket link, a bucket rod regeneration link and an unloading link in sequence; the first main oil way and the second main oil way are connected with the oil port P1 and the oil port P2 respectively. Compared with the prior art, an integral structure is adopted, the structure is compact, and different requirements of excavating execution mechanisms for flow pressure are met.

Description

technical field [0001] The invention relates to the technical field of hydraulic control, in particular to an electronically controlled multi-way valve used in a hydraulic system of a medium-sized excavator. Background technique [0002] As one of the key components of the excavator hydraulic system, the multi-way control valve is required to have the advantages of high working pressure, compact structure, low pressure loss, and easy installation and operation. Currently, the integral multi-way valve used in excavators has a valve core It has the disadvantages of complex structure, complicated casting of valve body flow channels, large pressure loss of oil in and out, and most of the pilot control methods are hydraulic control. There are many pilot paths, poor control flexibility, and unsatisfactory energy-saving effect. SUMMARY OF THE INVENTION [0003] Aiming at one of the defects or defects existing in the prior art, the present invention provides a new type of electron...
