Abstract

The invention discloses an electromagnetic direct-drive reversing multi-way valve, and belongs to the technical field of multi-way valves. A reversing valve core is slidably mounted in the valve coremounting hole in a valve body, an electromagnetic driving device is fixedly connected with each of the two ends of the valve core mounting hole in the valve body, an inner spigot is formed in each ofthe two ends of the valve core mounting hole in the valve body, an outer blocking platform is arranged at the end of the reversing valve core, a pressing ring is mounted at the end of the reversing valve core in a sleeving mode, the inner ring of the pressing ring is pressed on the outer side of the outer blocking platform, the outer ring of the pressing ring is located in the inner spigot in theend of the valve core mounting hole in the valve body, and a resetting spring is connected with the outer side of the pressing ring. According to the electromagnetic direct-drive reversing multi-way valve, the electromagnetic driving device is connected with each of the two ends of the valve core mounting hole, driven connection with the reversing valve core through the pressing ring and the resetting spring is achieved, the structural part is simplified, and the valve body can be more compact and light in weight; and the valve core is flexible and fast in reversing action and high in controllability, the reversing impact is small, and the reversing response speed of the multi-way valve can be increased by more than 100 milliseconds.

Description

technical field [0001] The invention relates to the technical field of multi-way valves, in particular to an electromagnetic direct-drive reversing multi-way valve. Background technique [0002] The multi-way valve is a combined reversing valve that is centrally arranged, and its main body is a plurality of reversing valves, which are mainly used in various construction machinery, lifting machinery and other walking machinery that need to realize multiple action controls. At present, most of the reversing methods of multi-way valves at home and abroad adopt manual reversing or control the pilot oil through a proportional solenoid valve to realize the reversing control of the reversing spool of the multi-way valve. Electromagnetic reversing has the advantage of relatively fast and sensitive response. Therefore, considering the basic constituent unit of the multi-way valve, the use of electromagnetic direct drive reversing can effectively improve the action response speed of t...
