Electric control device and valve

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. 本发明提供了种电动控制装置及阀门，涉及阀门的技术领域，包括电机和制动机构；其中：制动机构包括从动件和制动件，从动件与制动件接触配合以实现电机的制动；电机包括驱动件，驱动件与从动件连接，用于驱动从动件与制动件分离以解除电机的制动。本发明的目的在于提供种电动控制装置及阀门，能够实现刹车和自锁的功能，使闸阀不会再出现关闭反弹和关不严的现象。
