Abstract

The invention discloses a reversal valve of a steering hydraulic system of a bulldozer. The reversal valve is characterized in that a scarifier operating valve core mounting hole, a dozer blade operating valve core mounting hole and corresponding oil holes are formed in a valve body; a scarifier operating valve core is arranged in the scarifier operating valve core mounting hole in a penetrating manner; a dozer blade operating valve core is arranged in the dozer blade operating valve core mounting hole in a penetrating manner; the left end of the scarifier operating valve core is positioned through a second positioning seat; the second positioning seat is internally provided with a spring sliding seat; the spring sliding seat is internally provided with a second spring; a stop block is arranged at the left end of the second positioning seat; the left end of the dozer blade operating valve core is positioned through a first positioning seat; the first positioning seat is internally provided with a spring and a positioning sleeve; the positioning sleeve is arranged at the left end of the spring; a pressing cover is arranged below the positioning sleeve, and is internally provided with a pressing seat; and the pressing seat is internally provided with a first spring and a steel ball. The reversal valve has a servo function, and is simple and flexible to operate, and compact in structure.

Description

technical field [0001] The invention relates to a reversing valve of a steering hydraulic system of a bulldozer, belonging to the technical field of hydraulic systems. Background technique [0002] The current disadvantage of existing hydraulic systems is the need for good maintenance - since hydraulic components are precision components and work under high pressure, good maintenance is required to prevent rust, corrosion, dirt, oil deterioration, etc. . Steering valve: Connect the steering joystick, control the steering valve stem through the joystick, and move the spool to the required position for steering. Contents of the invention [0003] Purpose: In order to overcome the deficiencies in the prior art, the present invention provides a reversing valve of the bulldozer steering hydraulic system. [0004] Technical solution: In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: [0005] A reversing valve...
