The invention relates to an electric-control four-way valve structure for a vacuum tank type vehicle. The electric-control four-way valve structure comprises a fixing support, a first electric actuator and a second electric actuator; the fixing support is fixedly arranged on the vacuum tank type vehicle; the first electric actuator comprises a first shell fixedly installed on the fixing support and a first electric actuating mechanism arranged on the first shell; a connecting support is fixedly connected to the first electric actuating mechanism; and the second electric actuator comprises a second shell hinged to the connecting support and a second electric actuating mechanism hinged to a valve handle of a four-way ball valve. According to the electric-control four-way valve structure, thespecific structure of the existing four-way ball valve is not required to be changed, and the four-way ball valve can be conveniently controlled to change the state through additional arrangement ofthe two electric actuators, so that an existing sewage suction truck and an existing fecal suction truck can be improved at low cost, and the working efficiency of operators can be improved.
本发明涉及一种用于真空罐式车辆的电控四通阀结构,包括固定支架、第一电动执行器和第二电动执行器,所述固定支架固定安装在真空罐式车辆上,所述第一电动执行器包括固定安装在固定支架上的第一壳体以及设置在第一壳体上的第一电动执行机构,所述第一电动执行机构上固接有连接支架;所述第二电动执行器包括与连接支架铰接的第二壳体以及与所述四通球阀的阀柄铰接的第二电动执行机构。本发明不需要改变现有四通球阀的具体结构,通过增加两个电动执行器就能够很方便地实现控制四通球阀改变状态,因此可以对现有的吸污车、吸粪车低成本进行改进,提高操作人员的工作效率。
