In order to simplify the structure of switching valve groups and reduce the failure rate in the high pressure abrasive jet mixing system, a combined switch valve for the system has been designed. The combined switching valve can implement a motor to drive four spools for two open and two closed electric control switch of high pressure abrasive jet mixing system, which has the advantages of compact structure, small space occupation, convenient control and high reliability.
