The invention discloses a miniaturized electric valve which comprises a main valve body, an electric actuator and a driving assembly. The electric actuator drives the driving assembly to move in the main valve body; the main valve body comprises a front valve body, a middle valve body and a rear valve body which are coaxially arranged and communicate with one another; a valve clack seat is arranged between the rear valve body and the middle valve body; a valve clack piece is arranged on the valve clack seat; the driving assembly comprises a hollow valve element and a transmission assembly; the hollow valve element is coaxially arranged in the main valve body and is in sliding connection with the main valve body; the transmission assembly comprises a transmission shaft and a transmission ring; the transmission ring is arranged on the outer side of the hollow valve element in a sleeving mode; one end of the transmission shaft is connected with the electric actuator; the other end of the transmission shaft penetrates into the main valve body and is matched with the transmission ring; the electric actuator drives the transmission shaft to rotate; the transmission shaft drives the transmission ring to axially and linearly move; and the transmission ring drives the hollow valve element to axially and linearly move so as to be in opening and closing fit with the valve clack piece. According to the miniaturized electric valve provided by the invention, the appearance size is reduced, so that the miniaturized electric valve can be used in a small space.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a miniaturized electric valve. Background technique [0002] Electric valves refer to valves that are switched on and off by electric actuators, and are suitable for controlling media such as gas, steam, and liquid. At present, the existing electric valves are mainly divided into two types. One type of actuator outputs linear motion, and the spool of the valve also moves linearly; the other type of actuator outputs rotary motion, and the spool of the valve also rotates. For example, a rotary electric valve with a stator rotating outer rotor motor disclosed in Patent No. CN108282036A belongs to the field of motors and includes a stator rotating outer rotor motor. The stator rotating outer rotor motor includes a rotor, a rotating shaft and a stator , the rotor remains stationary, the rotating shaft is connected to the stator, and the stator and the rotating shaft rotate together. ...
