鑄鐵拍門的次要裝置在排水管道的尾端,用于避免外水倒灌。材質(zhì)分爲(wèi)不銹鋼、鑄鐵、型鋼、復(fù)合資料玻璃鋼)等多種資料。而拍門又分爲(wèi)很多種,比方,浮箱式拍門,平板式拍門,套筒式拍門等等,是裝置在江河邊排水管出口的一種單向閥,當(dāng)江河潮位高于出水管口,且壓力大于管內(nèi)壓力時(shí),拍門面板自動(dòng)封閉,以防江河潮水倒灌進(jìn)排水管道內(nèi)。目前拍門分爲(wèi)懸掛式,單節(jié)能式雙開門節(jié)能式雙開門,節(jié)能型等鑄鐵拍門型號(hào)。
Cast iron flapping door - secondary device at the end of drainage pipe, used to avoid backfilling of external water. Material is divided into stainless steel, cast iron, section steel, composite materials (FRP) and other information. There are many kinds of flapping doors, such as floating box flapping doors, flat flapping doors, sleeve flapping doors and so on. They are one-way valves installed at the outlet of river drainage pipes. When the river tide level is higher than the outlet and the pressure is greater than the pressure in the pipe, the flapping door panel automatically closes to prevent the River tide from pouring into the drainage pipes. At present, the clapping door is divided into hanging type, single energy-saving type, double-opening type and energy-saving type.
