style="text-indent:25px">減壓閥的防護(hù)設(shè)施：減壓閥安裝設(shè)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(guò)正常的壓力時(shí)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(dāng)減壓閥出現(xiàn)故障后，關(guān)閉減壓閥前后的切斷閥，打開(kāi)旁通閥，用手工調(diào)節(jié)流量，起到臨時(shí)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(hù)設(shè)施說(shuō)明。</p><p style="text-indent:25px">隨著防化學(xué)腐蝕的合成橡膠在蝶閥上的應(yīng)用，蝶閥的性能得以提高。由于合成橡膠具有耐腐蝕、抗沖蝕、尺寸穩(wěn)定、回彈性好、易于成形、成本低廉等特點(diǎn)，并可以根據(jù)不同的使用要求選擇不同性能的合成橡膠，以滿足蝶閥的使用工況條件。由于聚四氟乙烯(PTFE)具有耐腐蝕性強(qiáng)、性能穩(wěn)定、不易老化、摩擦系數(shù)低、易于成形、尺寸穩(wěn)定，并且可以通過(guò)填充、添加適當(dāng)?shù)牟牧细纳破渚C合性能，得到強(qiáng)度更好、摩擦系數(shù)更低的蝶閥密封材料，克服了合成橡膠的局限性。蝶閥又叫翻板閥，是一種結(jié)構(gòu)簡(jiǎn)單的調(diào)節(jié)閥。</p><div
