PARKER派克氣動(dòng)閥PHS520S-8適用于流量調(diào)節(jié)。由于蝶閥在管路中的壓力損失比較大，大約是閘閥的三倍，因此在選擇蝶閥時(shí)，應(yīng)充分考慮管道系統(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)原理于制作大口徑閥門(mén)。當(dāng)要求蝶閥作控制流量使用時(shí)，zui重要的是正確選擇蝶閥的尺寸和類(lèi)型，使之能恰當(dāng)?shù)?、有效地工作。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。
