style="text-indent:25px">減壓閥在修理拆裝減壓元件時，要謹慎細心，調換內密封件；清理雜物時，應因勢利導，不要用金屬棒、硬梗撬閥的活動部位，使用木榔頭和木柄敲擊震動，慢慢拆卸閥內部件。修理完畢后重新安裝時，一定要和閥門上的流向指示保持一致。如果需要將減壓閥安裝在熱水系統(tǒng)時，您必須在減壓閥和膨脹水箱之間安裝止回閥。這樣既可以讓膨脹水箱吸收由于熱膨脹而增加的水的體積，又可以防止熱水回流或壓力波動對減壓閥的影響，確保減壓閥長期正常工作。調壓閥批發(fā)哪家好對夾式蝶閥是用雙頭螺栓將閥門銜接在兩管道法蘭之間。</p><div

style="text-indent:25px">減壓閥選用標準：標準一在給定的彈簧壓力級范圍內，使出口壓力在大值與小值之間能連續(xù)調整，不得有卡阻和異常振動；標準二對于軟密封的減壓閥，在規(guī)定的時間內不得有滲漏；對于金屬密封的減壓閥，其滲漏量應不大于大流量的0.5%；標準三出口流量變化時,直接作用式的出口壓力偏差值不大于20%,先導式不大于10%；標準四進口壓力變化時，直接作用式的出口壓力偏差不大于10%，先導式的不大于5%；標準五通常，減壓閥的閥后壓力應小于閥前壓力的0.5倍；</p><p 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。依據(jù)密封件的強度，也可用于粉狀和顆粒狀介質。蝶閥適用于流量調節(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。減壓閥的流量特性：是指輸入壓力一定時，輸出壓力必須低于輸出流量的變化而變化的特性。</p><div
