Problems solved by technology

[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 energized, and the gate valve gate moves to close the valve seat. When the gate moves to the closed position, the signal is fed back to the electric gate valve. When the control device is powered off, because of the inertia, the motor rotor and gate valve gate will continue to move in the original direction, and the gate valve gate will collide with the switch limit device, causing an emergency stop, and at the same time, a reverse force will be generated through the transmission mechanism. Feedback to the rotor of the electric control device, the rotor of the motor rotates under the action of the force, the gate plate produces a reverse displacement, and the gate valve will rebound when it closes

Abstract

The invention provides an electric control device and a valve, which relate to the technical field of valves, including a motor and a braking mechanism; wherein: the braking mechanism includes a follower and a brake, and the follower and the brake are in contact and cooperate to realize The braking of the motor; the motor includes a driving part, the driving part is connected with the driven part, and is used for driving the driven part to separate from the braking part to release the braking of the motor. The purpose of the present invention is to provide an electric control device and a valve, which can realize the functions of braking and self-locking, so that the gate valve will no longer have the phenomenon of closing rebound and lax closing.

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 in normal operation, 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 one by one or the whole system due to system maintenance, the electric control device is energized to provide power support for the gate valve. closure. [0003] At present, the fully enclosed electric control device used in domestic electric gate valves, when the gate valve needs to be closed, after the electric control device is energized, it provides power to the gate valve, the gate valve gate moves to close the valve seat, and when the gate moves to the closed position...
