Electric valve

An electric valve, comprising a transmission mechanism, a valve core, and a valve body assembly, wherein the valve body assembly has a valve body cavity in which the valve core is located, and the transmission mechanism is in transmission connection with the valve core, wherein

• the electric valve further comprises a connecting seat fixedly connected to the valve body assembly, the connecting seat has a first through-hole, the transmission mechanism comprises an output shaft, one part of the output shaft is located in the first through-hole, and another part of the output shaft is located in the valve body cavity, and
• the electric valve further comprises a limiting bracket fixedly connected to the output shaft, the limiting bracket is located at one side, closer to the valve core, of the connecting seat, the limiting bracket and the connecting seat are arranged opposite to each other in an axial direction, and a predetermined gap exists between the limiting bracket and the connecting seat,
• the output shaft comprises a first stepped portion and a second stepped portion, the second stepped portion is closer to the valve core than the first stepped portion, the first stepped portion has a width in a radial direction greater than a width of the second stepped portion in the radial direction, one part of the second stepped portion is located in the first through-hole, another part of the second stepped portion is located in the valve body cavity.
