style="font-size:16px;">蝶閥的選用原則1、由于蝶閥相對于閘閥，球閥壓力損失比較大，故適應(yīng)于壓力損失要求不嚴的管路系統(tǒng)中2、由于蝶閥可以用流量調(diào)節(jié)，故在需要進行流量調(diào)節(jié)的管路中宜于選用3、由于蝶閥的結(jié)構(gòu)和密封材料的限制，不宜用于高溫，高壓的管路系統(tǒng)。一般工作溫度在300℃以下，公稱壓力在PN40以下。4、由于蝶閥結(jié)構(gòu)長度比較短，且又可以做成大口徑，故在結(jié)構(gòu)長度要求短的場合或是大口徑閥門（如DN1000以上），宜選用蝶閥。5、由于蝶閥*旋轉(zhuǎn)90°就能開啟或關(guān)閉，因此在啟閉要求快的場合宜選用蝶閥蝶閥***用于℃的各種介質(zhì)。閥桿只做旋轉(zhuǎn)運動，蝶板和</span><span
