style="font-size:16px;">蝶閥適用于流量調(diào)節(jié)。由于蝶閥在管路中的壓力損失比較**約是閘閥的三倍，因此在選擇蝶閥時(shí)，應(yīng)充分考慮管路系統(tǒng)受壓力損失的影響，還應(yīng)考慮關(guān)閉時(shí)蝶板承受管道介質(zhì)壓力的堅(jiān)固性。此外，還必須考慮在高溫下彈性閥座材料所承受工作溫度的限制。蝶閥的結(jié)構(gòu)長(zhǎng)度和總體高度較小，開(kāi)啟和關(guān)閉速度快，且具有良好的流體控制特性，蝶閥的結(jié)構(gòu)原理適合制作大口徑閥門。當(dāng)要求蝶閥作控制流量使用時(shí)，重要的是正確選擇蝶閥的尺寸和類型，使之能恰當(dāng)?shù)亍⒂行У毓ぷ?。通常，在?jié)流、調(diào)節(jié)控制與泥漿介質(zhì)中，要求結(jié)構(gòu)長(zhǎng)度短，啟閉速度快(1/4轉(zhuǎn))。低壓截止(壓差小)，推薦選用蝶閥。在雙位調(diào)節(jié)、縮口地通道、低噪聲、有氣穴和氣化現(xiàn)象，向大氣少量滲漏，具有磨蝕性介質(zhì)時(shí)，可以選用蝶閥。</span>
