The screw actuator features a simple structure, easy operation, and wide application, fully utilizing the screw's opening and closing force. Due to the long length and uneven surface of the screw, it is susceptible to natural factors when exposed to the air for long periods. Cleaning and rust removal of the screws are difficult and have low maintenance efficiency. Therefore, addressing the cleaning and rust removal issues of the spiral screw is significant for the maintenance and application of the screw actuator.
That is to say, if the gate cannot close due to its own weight, it can be controlled by pressure. Therefore, the spiral winch is widely used in the Yellow River's downstream water diversion projects with low head, small flow, high sediment concentration, and frequent sedimentation.
The main features of the screw-driven shutter are: it is vertical, with a simple overall structure, small land area, smooth operation, easy control, high manufacturing precision, and wide application.
Especially, the screw gate valve has a bidirectional control function that transmits tension and pressure during the operation of lifting the gate.
