style="text-indent:25px">減壓閥的防護設施：減壓閥安裝設施一般有三種形式。減壓閥前后裝有壓力表，方便觀察閥前和閥后的壓力。閥后還有裝有全封閉式的穩(wěn)定閥，以防減壓閥失效后，閥后壓力超過正常的壓力時起跳，包含閥后系統(tǒng)。泄水管裝在閥前切斷閥前面，主要是排水河沖洗作用，有的采用疏水閥。旁通管主要作用是當減壓閥出現(xiàn)故障后，關閉減壓閥前后的切斷閥，打開旁通閥，用手工調(diào)節(jié)流量，起到臨時流通作用，以便檢修減壓閥或更換減壓閥。以上就是減壓閥的一些防護設施說明。</p><p style="text-indent:25px">蝶閥使用場景：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大，還應考慮關閉時蝶板承受管道介質(zhì)壓力的堅固性。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。蝶閥的結構長度和總體高度較小，開啟和關閉速度快，且具有良好的流體控制特性，蝶閥的結構原理適合制作大口徑閥門。當要求蝶閥作控制流量使用時，重要的是正確選擇蝶閥的尺寸和類型，使之能恰當?shù)?、有效地工作。通常，在?jié)流、調(diào)節(jié)控制與泥漿介質(zhì)中，要求結構長度短，啟閉速度快（1/4轉(zhuǎn)）。低壓截止（壓差小），推薦選用蝶閥。蝶閥連接方式有法蘭連接、對夾連接、對焊連接及凸耳對夾連接。</p><div
