Embodiment Construction
[0017] See figure 1 The present invention is composed of two parts of the actuator 1 and the valve body 2. The actuator 1 is installed and fixed on the valve seat 4 on the top of the valve body through the lower bracket plate 3, and the drive motor 5 of the actuator 1 is connected to the transmission through the hook key 6 The nut 7 is connected, and the two ends of the transmission nut 7 are equipped with plane thrust ball bearings 32, the torque is greatly reduced, the opening is easy and labor-saving, and the hand can be twisted. However, the traditional technology cannot be twisted by hand, and can only be opened by the oil pump. The transmission nut 7 It also cooperates with the drive screw 8 with T-threads to change the rotational movement of the drive motor 5 into the up and down movement of the drive screw 8. The drive screw is connected to the valve shaft 10 through a coupling 9, which is equipped with anti-shock and shock absorption. Butterfly spring 31, a position si...
