Handwheel opening and closing machine

Using spiral screw transmission, it can control the up and down movement (gates, weir gates, gate valves, etc.) or rotational movement (disc valves, rotating weir gates, etc.) of the opened and closed machine, thereby realizing the opening and closing of valves or gates. Its mechanism is compact and reasonable, with large opening and closing force and a complete series, widely used in water plants, sewage treatment plants, various water supply and drainage projects, and hydraulic and hydropower projects for the lifting and adjustment of gates, weir gates, mud discharge valves and other equipment
