style="text-indent:25px">法蘭蝶閥門關(guān)嚴(yán)后，由于介質(zhì)或環(huán)境溫度的變化，閥門部件的熱膨脹會(huì)使閘板和閥座之間的壓力變大。這個(gè)力反映到閥桿螺紋上，就為再次開啟閥門帶來困難，所以開啟閥門時(shí)所需的轉(zhuǎn)矩(即加在閥桿螺母上的轉(zhuǎn)矩)一般要比關(guān)閉閥門時(shí)所需的轉(zhuǎn)矩來得大。此外，對于一對互相接觸的密封面來說，它們之間的樸摩擦系數(shù)也比動(dòng)摩擦系數(shù)大，所以要使它們從靜止?fàn)顟B(tài)產(chǎn)生相對位移時(shí)，必須加較大的力，以克服靜摩擦力。這一情況，在關(guān)閉后再次開啟的閥門中更加明顯。蝶閥液壓驅(qū)動(dòng)設(shè)備呈現(xiàn)缺點(diǎn)時(shí)，應(yīng)找到修理人員及時(shí)找到缺點(diǎn)，停止修理。</p><div

style="text-indent:25px">蝶閥又叫翻板閥，是一種結(jié)構(gòu)簡單的調(diào)節(jié)閥，可用于低壓管道介質(zhì)的開關(guān)控制的蝶閥是指關(guān)閉件（閥瓣或蝶板）為圓盤，圍繞閥軸旋轉(zhuǎn)來達(dá)到開啟與關(guān)閉的一種閥。閥門可用于控制空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品、液態(tài)金屬和放射性介質(zhì)等各種類型流體的流動(dòng)。在管道上主要起切斷和節(jié)流作用。蝶閥啟閉件是一個(gè)圓盤形的蝶板，在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn)，從而達(dá)到啟閉或調(diào)節(jié)的目的。在工業(yè)生產(chǎn)中，蝶閥是一個(gè)很關(guān)鍵的機(jī)械裝置，是很常見的。蝶閥裝置前道確認(rèn)產(chǎn)品功能和介質(zhì)流向箭頭是否與運(yùn)動(dòng)工況相符。蝶閥廠</p><p style="text-indent:25px">蝶閥未清洗前絕不允許關(guān)閉蝶板，以免損壞密封圈。上海蝶閥廠商</p><p style="text-indent:25px">蝶閥主要由閥體、、閥軸、軸承、密封裝置、操作機(jī)構(gòu)及附屬部件組成。蝶閥在完全開啟時(shí)，具有較小的流阻。當(dāng)開啟在大約15°~70°之間時(shí)，又能進(jìn)行靈敏的流量控制，因而在大口徑的調(diào)節(jié)領(lǐng)域，蝶閥的應(yīng)用非常普遍。由于蝶閥蝶板的運(yùn)動(dòng)帶有擦拭性，故大多數(shù)的蝶閥可用于帶懸浮固體顆粒的介質(zhì)。依據(jù)密封件的強(qiáng)度，也可用于粉狀和顆粒狀介質(zhì)。蝶閥適用于流量調(diào)節(jié)。由于蝶閥在管中的壓力損失比較，大約是閘閥的三倍，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)蝶板承受管路介質(zhì)壓力的強(qiáng)度。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。上海蝶閥廠商</p><p
