The
MF type open pole type copper-lined cast iron square gate is mainly used for irrigation and flood control. Water supply and drainage projects such as water conservancy and hydropower sewage treatment plants and waterworks are used to cut off or dredge water flow.

Structure and working principle
The gate adopts open rod type, flat reinforced type, attached wall installation, suitable for the raised rod type square orifice gate installed on the wall, and its flat inner bottom is closely fitted with the parallel wall; It is driven by the opening and closing machine to rotate the opening and closing nut, and under the action of the trapezoidal thread, the screw drives the gate body to run up and down to achieve the role of truncating or dredging the water flow.
