style="text-indent:25px">蝶閥在完全開啟時，具有較小的流阻。當開啟在大約15°~70°之間時，又能進行靈敏的流量控制，因而在大口徑的調(diào)節(jié)領域，蝶閥的應用非常普遍。由于蝶閥蝶板的運動帶有擦拭性，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**約是閘閥的三倍，因此在選擇蝶閥時，應充分考慮管路系統(tǒng)受壓力損失的影響，還應考慮關閉時蝶板承受管路介質(zhì)壓力的強度。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。蝶閥價錢多少蝶閥處于徹底開啟方位時，蝶板厚度是介質(zhì)流經(jīng)閥體時的阻力。</p><div

style="text-indent:25px">注意減壓閥的減壓保障系統(tǒng)。無論選用比例式還是可調(diào)式減壓閥，其減壓比P1∶P2不宜選擇過大，一般應控制在5∶1之內(nèi)。超過這個范圍易產(chǎn)生氣蝕現(xiàn)象，損壞閥件，產(chǎn)生嘯叫噪音。有些活塞式減壓閥，制造廠在其閥體上加工一個直徑1.5mm左右的小孔，其功能是讓閥芯運動時起到透吸氣作用，維護管理時應注意千萬不要將小孔塞住，否則影響減壓閥的正常運行。減壓閥的減壓保障系統(tǒng)是重中之重，工作人員在維護管理時要遵守規(guī)范，否則操作不當會直接影響減壓閥的正常運轉(zhuǎn)工作。</p><p style="text-indent:25px">在閥門安裝時，為了保持防止金屬，沙粒等異物侵入閥內(nèi)，損壞密封面，需要設置過濾器和沖洗閥;為了保持壓縮空氣凈化，在閥前需要設置油水分離器，或者空氣過濾器;考慮到操作時能檢查閥門工作狀態(tài)，需要設置儀表和檢查閥;為了保持操作溫度，在閥門外部設置保溫設施;為了閥后的安裝，需要設置穩(wěn)定閥或者止回閥;考慮到閥門的連續(xù)工作，便于危險，設立了并聯(lián)系統(tǒng)或旁路系統(tǒng)等。總之，閥門安裝時要注意遵守相關的規(guī)范來進行操縱，這是很重要的。減壓閥可將閥前管路較高的水壓減少至閥后管路所需的水平。</p><div
