Abstract

The invention provides an electric control device and a valve, relating to the technical field of valves. The electric control device comprises a motor and a braking mechanism, wherein the braking mechanism comprises a driven component and a braking component, the driven component is in contact fit with the braking component so as to realize the brake of the motor; the motor comprises a driving component, and the driving component is connected with the driven component and is used for driving the driven component to be separated from the braking component so as to release the braking of the motor. According to the electric control device and the valve, the braking and self-locking functions can be realized, and the phenomena that a gate valve is rebounded during the closing and cannot be tightly closed are avoided.

Description

technical field

[0001] The invention relates to the technical field of valves, in particular to an electric control device and a valve. Background technique

[0002] The electric control device is the actuator of the gate valve, which provides power support for the opening and closing of the gate valve. When the system is running normally, the electric control device is in a power-off state and the gate valve is in an open state. When an accident occurs in the system or the system needs to be isolated section by section or the whole system due to system maintenance, the electric control device is powered on to provide power support for the gate valve. closure.

[0003] The fully enclosed electric control device used in domestic electric gate valves, when the gate valve needs to be closed, the electric control device provides power to the gate valve after the electric control device is powered on, and the gate valve gate moves to close the valve seat. When the gate moves to ...
