Structural characteristics and working principles of cast iron gates
Cast iron gates are composed of door frames, gate plates, guide rails, sealing strips, transmission screws, lifting block nuts/lifting lugs and adjustable sealing mechanisms. The door frames and gate plates are composed of Made of high-quality gray cast iron or ductile iron, the guide rails are symmetrically arranged and connected to the ends of both sides of the door frame with stainless steel bolt positioning pins (for gates with medium and small diameters, the guide rails can be cast into one body with the door frame). The length of the guide rails is generally the full length of the gate. The opening height is /~ so the overall structure has high strength, high rigidity, good wear resistance, corrosion resistance, and large pressure bearing capacity.
