Abstract

The invention discloses a two-position three-way reversing valve which comprises a valve body and a positioning sleeve arranged in the valve body. A control opening is formed in one end of the positioning sleeve; a valve rod assembly is arranged at one end of the control opening; a valve column matched with the valve rod assembly in action is arranged at one end of the valve rod assembly; a middlevalve sleeve is further arranged in the valve body; a valve seat is arranged on one side of the middle valve sleeve; a limiting opening is formed in the valve seat; and a steel ball capable of beingjacked open by the valve column is arranged in the limiting opening. The two-position three-way reversing valve provided by the invention is simple and reasonable in structure, reversing is achieved in a hydraulic mode, the reversing mode is simple and convenient, meanwhile, working pressure and flow are stable, and the requirements of a control system are easily met.

Description

technical field [0001] The invention belongs to the technical field of hydraulic equipment control, and in particular relates to a two-position three-way reversing valve. Background technique [0002] A hydraulic reversing valve is a directional control valve that controls fluid pressure to push a spool to change the direction of fluid flow. The current spool push methods mainly include manual, electromagnetic and so on. Most of these driving methods are limited by the power of the conversion device, so that the working pressure is low, the control flow is small, it is difficult to meet the requirements of the control system, and the commutation is more cumbersome. Contents of the invention [0003] (1) Technical problems to be solved [0004] In order to solve the above problems, the present invention proposes a two-position three-way reversing valve with simple reversing and stable flow. [0005] (2) Technical solution [0006] A two-position three-way reversing valv...
