This invention relates to the field of industrial valve technology. It discloses an intelligent manual
ball valve with electronic locking function, comprising a valve body, a valve ball, a
valve stem, and a
handle, and further including an electronic locking unit located above or to the side of the
valve stem. The electronic locking unit includes a housing, a
locking mechanism located within the housing, an electric
actuator, and a control module. The
locking mechanism restricts the rotation of the
handle relative to the valve body in the locked state. The electric
actuator drives the
locking mechanism to switch between locked and unlocked states. The control module is electrically connected to the electric
actuator and an external
signal interface. The control module is configured to output a drive
signal to the electric actuator based on control information from at least one local authorized operation,
remote control command, and process
interlock signal, thereby controlling the locking mechanism to switch between locked and unlocked states, thus achieving electronic locking and unlocking of the
handle. The
valve opening and closing actions are completed by the operator through manual rotation of the handle.
