Manual flat gate valve for rainwater wells, soft-sealed square gate valve, 1. Before installing the slide gate valve, inspect the valve cavity and sealing surfaces to ensure no dirt or sand particles are attached;2. Bolts at all connection points must be tightened evenly;3. Check the packing area to ensure it is tightly compressed, guaranteeing both the sealing of the packing and the flexible opening of the gate;4. Before installation, users must verify the valve model, connection dimensions, and pay attention to the flow direction of the medium to ensure compatibility with valve requirements;5. When installing the valve, users must reserve necessary space for valve actuation;6. Wiring of the actuation device must follow the circuit diagram;7. The slide gate valve requires regular maintenance and should not be arbitrarily impacted or squeezed to avoid compromising the seal.

Precautions and characteristics of electric slide gate valves: The opening and closing component of a slide gate valve is the gate, which moves perpendicular to the fluid flow direction. Slide gate valves can only be fully open or fully closed and cannot be used for regulation or throttling. The gate has two sealing surfaces, with the most common type being the wedge gate valve, where the two sealing surfaces form a wedge shape. The wedge angle varies depending on valve parameters, typically 50 degrees. The gate of a wedge slide gate valve can be made as a single piece, known as a rigid gate, or designed to allow slight deformation to improve manufacturability and compensate for deviations in the sealing surface angle during processing—this is called an elastic gate. When the slide gate valve is closed, the sealing can rely solely on medium pressure, meaning the medium pressure presses the gate's sealing surface against the opposite seat to ensure a seal, which is self-sealing. Most slide gate valves use forced sealing, requiring external force to press the gate against the seat when closed to ensure sealing. Slide gate valve sealing structures can be classified as soft seal or hard seal.
