Cast iron lifting and regulating weir gate.The cast iron lifting and regulating weir gate is composed of a valve door frame, weir plate, screw rod, guide rail, and hoist. By driving the up and down movement of the screw rod through the hoist, the water level difference between the weir gate and the liquid surface is changed, thereby achieving the purpose of changing the water level and regulating the flow. This equipment is made of high-quality gray cast iron. There is a bronze alloy sealing surface on the mouth frame, which is directly connected and matched with the hoist. It has the characteristics of simple structure, good water stoppage, wide adjustment range, and convenient maintenance and management. It is suitable for industries such as irrigation, waterworks, flood control, and sewage treatment, and plays a role in regulating the water level of reservoirs or controlling the flow of channels.
