[0032] The inner surface of the double-layer sealing ring 9 is in contact with the outer surface of the actuator shaft 5, and the outer surface of the double-layer sealing ring 9 is in contact with the inner surface of the positioning seal 10, and the positioning seal 10 is a hollow ring-shaped design with a toothed groove on the outside, and the upper end of the positioning seal 10 is snap-connected with the lower surface of the housing 1;

[0033] During the normal installation of the actuator, the housing 1 is plugged into the outer shell of the valve body through the toothed groove on the surface of the positioning seal 10, so that the housing 1 can be accurately positioned with the outer shell of the valve body, and the plug-in seal between the positioning seal 10 and the outer shell of the valve body is used to achieve preliminary waterproofing.

Embodiment 2

[0035] This embodiment is disclosed on the basis of the embodiment 1: a directional fine-tuning structure is provided inside the housing 1 for fine-tuning the initial installation angle of the motor 4;
