The screw shutter is one of the leading products of Rongchuang Hydropower Machinery Factory, primarily used in hydroelectric and water conservancy projects, municipal construction, water supply and drainage, aquaculture, and agricultural water conservancy construction. The product range includes screw-type shutters and winch-type shutters. The screw-type shutters include: LQ hand-cranked screw shutter (2T-20T), LQ hand-held electric screw shutter (3T-50T), LQ side-pulled screw shutter (0.5T-3T), LQ hand-push screw shutter (0.5T-2T), LQ handwheel screw shutter (0.5T-2T), and LQ dual-hoist hand-held electric shutter (2-50T).

The classification of screw-type gate valves is extremely diverse. For instance, manual hand-cranked valves, hand-held/electric dual-use valves, side-tilt valves, directly connected valves, and various mechanical gate valves, etc. Different types of valves have many unique functions, often leading to confusion during selection, which can severely affect their operation. During use, each type of screw gate valve has distinct functionalities, so it's crucial to choose the appropriate one for the application.

Screw type gate valve installation and maintenance:

1. Ensure the base layout plane is level at 180°; the contact area between the machine base and the base layout plane must exceed 90%; the screw shaft axis must be perpendicular to the horizontal plane measured on the weir platform; it should also be perpendicular to the hinge holes of the weir plate to prevent the screw from tilting, which could lead to localized stress and damage to the machine components.

2. Place the actuator at the installation position. Fit a limit disk onto the screw, then thread the screw into the actuator from the bottom of the beam. Once the screw is visible above the actuator, add the limit disk. The bottom of the screw is connected to the gate.

3. The installation of the foundation building for the opening and closing machine must be stable and safe. The concrete for the machine base and foundation components must be cast according to the drawings. It is strictly prohibited to remove or alter the temporary supports for the opening and closing machine before the concrete reaches the designed strength, and it is also forbidden to conduct trial adjustments or trial operations.

4. Install the opening and closing machinery so that it aligns with the midpoint of the gate's lifting centerline, ensuring the longitudinal and transverse centerlines have no deviation beyond ±3mm, and the elevation deviation is no more than ±5mm. Subsequently, pour the second-stage concrete or connect it to the pre-buried steel plate.

5. Installation of electrical equipment for opening and closing mechanisms complies with drawings and specifications; all electrical equipment is reliably grounded.

6. After the installation of each opening and closing machine is complete, clean the machinery, repair any damaged protective paint, and apply lubricant.

Our Rongchuang manufactured screw-driven shutdown valves are versatile, easy to install, simple to operate, with excellent wear resistance and a long service life, and good corrosion resistance.
