Disclosure of Invention
In order to overcome the not enough of background art, the utility model discloses an aim at moves the piece through the locking of motor control and removes the tight valve rod of clamp through designing a ball valve with automatic locking function, thereby can realize that a plurality of ball valve locks of one-key control die for the staff can't rotate the valve rod during the valve rod lock is dead, avoids making proruptive incident because of the maloperation in stages such as maintenance, debugging.
The utility model adopts the technical proposal that: a ball valve with an automatic locking function comprises a ball valve body, wherein a valve rod and a valve ball are arranged in the ball valve body, one end of the valve rod is fixedly connected with the valve ball, the valve rod is rotatably connected with the ball valve body, the ball valve also comprises a locking mechanism and a transmission mechanism, the locking mechanism is fixed on the valve rod, and the transmission mechanism is connected with the locking mechanism and controls the locking mechanism to lock the valve rod; locking mechanism includes that locking frame, slide bar, double threaded screw and locking move the piece, locking frame with the ball valve main part is connected, and the double threaded screw is rotatory to be installed on locking frame, locking moves a both ends and is connected with slide bar and double threaded screw respectively, drive mechanism is connected with double threaded screw, and two locks move the piece through double threaded screw's transmission towards in opposite directions or opposite direction synchronous motion.
Further, drive mechanism includes reduction gear and motor, reduction gear one end is connected with the motor, the other end with the double-end screw is connected, and the motor passes through reduction gear control double-end screw and just reverses.
Furthermore, a locking groove is formed in the valve rod, and the locking moving block limits the valve rod to rotate through the locking groove.
Furthermore, the locking moving block is provided with a limiting groove matched with the locking groove.
By adopting the technical scheme, when the valve rod rotates to an open or closed state, the double-end screw is controlled to rotate through the motor, so that the locking moving blocks at two ends are close to the valve rod at the same time, and when the locking moving blocks move to the fit locking grooves, the motor stops working; when the flow in the ball control ball valve main part is rotated to needs, move the piece through the motor control locking and keep away from the valve rod, the valve rod loses the spacing that the locking moved the piece, can normally operate the valve rod rotatory, through motor control valve rod locking, can play a key automated control's effect, after the locking valve rod, the unable rotatory valve rod of staff avoids staff's maloperation and brews proruptive incident.
The utility model discloses further set up to, be equipped with the stopper on the slide bar, locking is moved and is equipped with spacing sensor on the piece.
Furthermore, an indicator light is arranged on the locking frame.
By adopting the technical scheme, the limit sensor is the travel switch, when the locking moving block moves to the position of the limit block, the travel switch sends a signal, so that the motor stops running, the motor is prevented from being burnt down due to long-time running, the valve rod is in a locking state at the moment, the indicating lamp sends red light, the worker can be intuitively warned to prohibit operating the valve rod, and the safety accident is avoided.
The embodiments of the present invention will be further explained with reference to the drawings.
