Abstract
The utility model discloses a valve and a driving mechanism of the same. The valve is a non-rising stem sluice valve. The driving mechanism comprises a worm, a worm gear and a motor. The motor drives the worm to rotate and the worm and the worm gear are engaged in transmission mode. The valve rod of the non-rising stem sluice valve is fixedly connected with a middle hole of the worm. The valve and a valve plate are trapezoidal screw thread pairs. The worm is drove through a coupler by using the motor as a power source of a whole driver and the worm and the worm gear are engaged in transmission mode. The valve rod of the non-rising stem sluice valve is fixedly connected with the middle hole of the worm. Rotation of the worm gear drives rotation of the valve rod. Because the valve rod and a valve plate are trapezoidal screw thread pairs, the aim of opening and closing the valve is achieved. Because the trapezoidal screw thread pairs, the worm gear and the worm are all of self-locking performance, opening position of the valve is locked by a driver at the moment when the motor loses power, and thereby external interferences cannot change the opening position of the valve.
