并能在進口壓力及流量變動時，利用本身介質(zhì)能量保持出口壓力基本不變的閥門。減壓閥分直接作用式和先導式，見圖1-37～圖1-40.⑴直接作用式直接作用式減壓閥是用壓縮彈簧、重物或重力杠桿以及壓縮空氣加載。通過膜片、活塞或波紋管直接進行壓力控制的閥門。這種閥門結構簡單、耐用。在比較惡劣的工況下，只要維護得當，也能有很長的壽命。雖然直接作用式的壓力調(diào)節(jié)不像先導式那么精確，但是造價低。可以***地用于不必要做精確控制的場合。常用的直接作用式減壓閥按結構形式分有：彈簧薄膜式減壓閥、活塞式減壓閥、波紋管式減壓閥和杠桿式減壓閥。彈簧薄膜式減壓閥是采用膜片作敏感元件來帶動閥瓣運動的減壓閥。它的靈敏度高，宜用于溫度和壓力不高的水和空氣介質(zhì)管道上?；钊綔p壓閥是采用活塞作敏感元件來帶動閥瓣運動的減壓閥。由于活塞在汽缸中承受的摩擦力較大，靈敏度不及薄膜式減壓閥。因此，適用于承受溫度、壓力較高的以蒸汽和空氣等為工作介質(zhì)的管道和設備上。波紋管式減壓閥是采用波紋管作敏感元件來帶動閥瓣運動的減壓閥。它宜由于介質(zhì)參數(shù)不高的蒸汽和空氣等潔凈介質(zhì)的管道上。不能用于液體的減壓。更不能用于含有固體顆粒介質(zhì)的管道上。因此。</p><p

閥門養(yǎng)護工作看似簡單，其實不然。工作中常有被忽視的方面。***、閥門注脂時。常常忽視注脂量的問題。注脂***加油后，操作人員選擇閥門和注脂聯(lián)結方式后，進行注脂作業(yè)。存在著二種情況：一方面注脂量少注脂不足，密封面因缺少潤滑劑而加快磨損。另一方面注脂過量，造成浪費。在于沒有根據(jù)閥門類型類別，對不同的閥門密封容量進行精確的計算?？梢砸蚤y門尺寸和類別算出密封容量，再合理的注入適量的潤滑脂。第二、閥門注脂時，常忽略壓力問題。在注脂操作時，注脂壓力有規(guī)律地呈峰谷變化。壓力過低，密封漏或失效，壓力過高，注脂口堵塞、密封內(nèi)脂類硬化或密封圈與閥球、閥板抱死。通常注脂壓力過低時，注入的潤滑脂多流入閥腔底部，一般發(fā)生在小型閘閥。而注脂壓力過高，一方面檢查注脂嘴，如是脂孔阻塞判明情況進行更換；另一方面是脂類硬化，要使用清洗液，反復軟化失效的密封脂，并注入新的潤滑脂置換。此外，密封型號和密封材質(zhì)，也影響注脂壓力，不同的密封形式有不同的注脂壓力，一般情況硬密封注脂壓力要高于軟密封。第三、閥門注脂時，注意閥門在開關位的問題。球閥維護保養(yǎng)時一般都處于開位狀態(tài)，特殊情況下選擇關閉保養(yǎng)。其他閥門也不能一概以開位論處。烏魯木齊黃銅絲扣閘閥</p><p
