The Screw Actuated Gate Valves are one of Rongchuang Hydropower Machinery Factory's leading products, primarily used in hydropower and water conservancy, municipal construction, water supply and drainage, aquaculture, and agricultural water conservancy projects. The product range includes screw actuated gates and winch gates. The screw actuated gates include: LQ Hand Crank Screw Actuated Gate (2T-20T), LQ Handheld Electric Screw Actuated Gate (3T-50T), LQ Side Swing Screw Actuated Gate (0.5T-3T), LQ Hand Push Screw Actuated Gate (0.5T-2T), LQ Handwheel Screw Actuated Gate (0.5T-2T), and LQ Dual Hoist Handheld Electric Two-in-One Actuated Gate (2-50T).

The classification of screw-type gate valves is extremely diverse. For instance, manual hand-cranked gates, hand-electric dual-use gates, side-tilt gates, direct-drive gates, and a variety of mechanical gates, among others. Different types of gates offer numerous functionalities, often leading to confusion during selection, which can severely impact their operation. During use, various gate valves have distinct functions, so it's essential to choose the appropriate one for the job.

Screw-type Gate Opener Installation and Maintenance:

1. Ensure the foundation layout plane is level at 180°; the contact area between the machine base and the foundation layout plane must exceed 90%; the screw shaft axis must be perpendicular to the level plane measured on the gate platform; it should also be perpendicular to the hinge holes on the gate plate to avoid the screw shaft tilting and cause localized stress that could damage the machinery parts.

2. Position the actuator at the installation site. Place a limit disc over the screw, then thread the screw from the bottom of the beam into the actuator. Once the screw is visible above the actuator, fit the limit disc onto it. 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 shall be cast according to the drawings. It is prohibited to remove or alter the temporary supports for the opening and closing machine before the concrete reaches the designed strength, and it is strictly forbidden to conduct trial adjustments or trial operations.

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

5. Installation of electrical equipment for actuators, in compliance with the drawings and specifications, all electrical equipment is securely grounded.

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

The screw actuated shut-off valves produced by Rongchuang are versatile, easy to install, simple to operate, have excellent wear resistance, and a long service life with good corrosion resistance.
