Abstract

The invention provides a fluid direction conversion device which comprises a body and a conversion control part. The body comprises a conversion base. The conversion base is provided with a fluid inlet hole, a fluid outlet hole, a first connection hole and a second connection hole. The first connection hole and the second connection hole are connected with an external sealing device. The conversion control part is connected with the conversion base. The conversion control part is provided with a first connection pipe, a second connection pipe and a third connection pipe. The connection positions of the three connection pipes are changed, so that the conversion control part works in different stations. In the second station, fluid flows into the second connection hole and flows out of the first connection hole, and fluid circulation in the first direction is achieved. In the third station, fluid flows into the first connection hole and flows out of the second connection hole, and fluid circulation in the second direction is achieved.

Description

technical field [0001] The invention relates to the field of hydraulic machinery, and in particular to a fluid direction conversion device. Background technique [0002] A fluid diverter is a component that changes the direction of fluid. In order to realize the reciprocating movement of the piston in the hydraulic cylinder, it is usually necessary to install a fluid conversion device in the hydraulic cylinder that can change the direction of the oil circuit. There are usually two structures of existing hydraulic cylinders. One is: the oil circuit in the hydraulic cylinder can only circulate in one direction after entering the hydraulic cylinder body, that is, it can only drive the piston to move forward, and the retreat of the piston requires manual oil drainage. It can be realized only after the operation, and it is very inconvenient for users to use, and the operation efficiency is very low. [0003] Another method is: in order to realize the automatic retraction of the...
