Abstract
An electronic expansion valve comprising a screw rod and a motor provided with an output shaft. The output shaft is transmissively connected to the screw rod via a gear system. The gear system is supported on a gear base. The screw rod passes through the gear base. The electronic expansion valve also comprises a valve base provided with valve cavity and a motor housing arranged on the exterior of the motor. The gear base is further arranged within the valve cavity. The upper end part of the valve base is further connected to the lower end part of the motor housing. The structural design of the electronic expansion valve reduces the number of sealed parts for same, thus effectively lowering the probability of leakage and simplifying the assembly structure thereof.
