Description

Technical Field

[0001] The utility model relates to the technical field of electric actuators, in particular to an electric actuator with a waterproof connection bracket. Background Art

[0002] Patent document CN218913771U discloses an electric regulating butterfly valve equipped with a distribution plate, which relates to the technical field of butterfly valves, including a valve body and an electric actuator, wherein the output end of the electric actuator is connected to a valve stem that penetrates the inside of the valve body, and the outer wall of the valve stem is located inside the valve body and is welded with a valve plate, and a distribution plate is welded on one side of the outer wall of the valve plate, and a plurality of distribution holes are formed on one end of the outer wall of the distribution plate. The utility model realizes that the rotation of the valve stem is controlled by the angular stroke electric actuator inside the electric actuator by setting the distribution plate and the distribution holes, so that when the valve stem rotates and drives the valve plate to rotate, the valve plate drives the distribution plate to rotate, and in the process of opening the valve plate from the closed state, the flow rate gradually increases through the side of the valve plate away from the distribution plate, and at the same time, the number of the flow rate through the distribution holes gradually increases, so that the flow rate through the valve body is in a good linear relationship with the opening under the action of the distribution plate and the distribution holes.

[0003] However, the butterfly valve is directly connected to the electric actuator. When water leaks at the connection between the butterfly valve and the electric actuator, the water source will directly enter the electric actuator and cause damage to the electric actuator. Therefore, it is necessary to improve such a structure to overcome the above defects. Utility Model Content
