Cast Iron镶铜Gate Structure Features
It features a unique outer arc design, with a rational structure and even stress distribution. Made of high-quality gray cast iron or ductile iron, or stainless steel, the water-stopping seal face is lined with copper strips or rubber. After precise machining and fitting, it achieves a flat contact seal with excellent sealing performance. In case of a decline in water-stopping performance, the issue can be resolved by adjusting the wedge block device.
Cast Iron镶Copper Square Gate
The cast iron镶copper square gate consists of components such as the door frame, gate plate, guide rail, sealing strip, transmission screw, lifting block nut/hook, and adjustable sealing mechanism. Both the door frame and gate plate are made of high-quality gray cast iron or ductile iron. The guide rails are symmetrically arranged on both sides and securely fastened to the door frame ends with stainless steel bolts and locating pins (for gates with medium to small diameters, the guide rail can be cast integrally with the door frame). The length of the guide rail is generally 1/2 to 1/3 of the full opening height of the gate, resulting in a structure with high overall strength, rigidity, wear resistance, corrosion resistance, and high pressure-bearing capacity.
2. Sealed through wedging by the wedge device, the sealing material is copper alloy or rubber, which has been precisely machined and matched, ensuring good sealing properties.
3. Features pre-buried steel plate or bolted installation for easy assembly, adjustment, operation, and maintenance, with a long service life.
A wide variety of specifications, with great adaptability.
5. Used in conjunction with opening and closing machines, the gate serves as the working component, while the machine is responsible for the operation of opening and closing the gate. The machine is powered by human effort, an electric motor, or pneumatic and hydraulic systems, which drive the transmission mechanism's gears, worm gears, and screws. This movement drives the rotation of the transmission nut or screw, causing the gate shaft to move vertically up and down, thereby opening or closing the gate to achieve the purpose of water supply, shutting off water, or adjusting water levels.
