Abstract

The invention discloses an integral manual multi-path reversing valve. A three-position slide valve hole passes through a left oil return cavity, a four-position slide valve left oil inlet cavity, a three-position slide valve left oil inlet cavity, a three-position slide valve left oil outlet cavity, a middle oil return cavity, a three-position slide valve right oil outlet cavity, a three-position slide valve right oil inlet cavity, a four-position slide valve right oil inlet cavity and a right oil return cavity in turn from the left to right. A four-position slide valve hole passes through the left oil return cavity, the four-position slide valve left oil inlet cavity, a four-position slide valve left oil outlet cavity, the middle oil return cavity, a four-position slide valve right oil outlet cavity, the four-position slide valve right oil inlet cavity and the right oil return cavity in turn from the left to right. A flow passage in a valve body of the integral manual multi-path reversing valve has a simple structure and reasonable arrangement; and the integral manual multi-path reversing valve is convenient to process and manufacture and has low cost.

Description

technical field [0001] The invention relates to a multi-way directional valve, in particular to an integral manual multi-way directional valve. Background technique [0002] Chinese Patent No. 2008200173585 discloses an integral manual multi-way valve, which realizes one oil inlet, four The conversion of the flow direction of the hydraulic oil between the oil outlet and an oil return port, the structure of the flow channel in the valve body of the valve is complicated, and the processing and manufacturing costs are high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an integral manual multi-way reversing valve with a simple oil passage structure in the valve body. [0004] In order to solve the above technical problems, the present invention includes a valve body, a right one-way valve, a safety valve, a three-position spool valve, a four-position spool valve, a four-position spool valve positioning mechanism,...
