| 铸铁闸门有以下特点： 布置简单，结构紧凑，节省空间；运行维护简单，减少运行费用，但铸铁闸门的造价比钢闸门略高一些。 耐腐蚀性强。门体和门框的材料采用铸铁，止水面镶铜合金或不锈钢等耐腐蚀材料，防腐能力强，特别适用于污水或海水环境中。有特殊要求的地方还可以采用镍铬合金铸铁等耐腐蚀性更强的材料。 铸铁闸门的止水副采用整体加工，止水效果好，金属止水使用寿命长。 Cast iron gate has the following characteristics: simple layout, compact structure, space saving; simple operation and maintenance, reduce operating costs, but the cost of cast iron gate is slightly higher than that of steel gate. Strong corrosion resistance. The material of the door body and frame is cast iron, and the water-proof surface is inlaid with copper alloy or stainless steel, which has strong anti-corrosion ability. It is especially suitable for sewage or seawater environment. Where there are special requirements, nickel-chromium alloy cast iron and other materials with stronger corrosion resistance can also be used. The water-stop pair of cast iron gate is processed as a whole, which has good water-stop effect and long service life of metal water-stop. |
