AI Technical Summary

Technical Problem

The existing high-pressure oil supply rotary assembly uses a separate design for the rotary solenoid valve and the opening/closing solenoid valve, which has limitations and cannot be adaptively adjusted according to the shape and angle of the mounting surface.

Method used

The rotary solenoid valve and the opening/closing solenoid valve are integrated into a single valve block and used in conjunction with a flow divider and a rotary speed control valve. The design of the base, support seat, flat plate, and curved plate allows for adjustment of the installation distance and angle, improving ease of operation.

Benefits of technology

The integrated design of rotary solenoid valve and opening/closing solenoid valve has been achieved, which can be adaptively adjusted according to the shape and angle of the mounting surface, improving the ease of operation and stability.

Abstract

The utility model discloses an improved high -pressure oil oil supply rotation assembly structure belongs to high -pressure oil oil supply rotation assembly technical field, including valve block, install rotation solenoid valve, open -and -close solenoid valve, shunt and rotation speed regulating valve on the valve block, through with the rotation solenoid valve and open -and -close solenoid valve integration to a valve block, and cooperate shunt and rotation speed regulating valve use, excavator high -pressure oil enters valve block IN mouth from the broken hammer pipeline, then divides into two -way supply rotation oil circuit and shunt oil circuit. Rotation oil circuit supplies rotation solenoid valve after through rotation speed regulating valve and rotates the flow to the flow required by rotation motor, through the coil of rotation solenoid valve two ends respectively energized can realize the commutation to rotation action. Another way supplies open -and -close solenoid valve, and open -and -close solenoid valve oil circuit can realize oil circuit 360 degrees arbitrary rotation and oil circuit's one divides into two through shunt, and supplies oil for open -and -close two oil cylinders.
