常用的先導(dǎo)式減壓閥按結(jié)構(gòu)形式分有：先導(dǎo)活塞式減壓閥、先導(dǎo)波紋管式減壓閥和先導(dǎo)薄膜式減壓閥。⑶減壓閥選用時(shí)應(yīng)注意的幾個(gè)問(wèn)題減壓閥應(yīng)用范圍***，包括蒸汽、壓縮開(kāi)啟、工業(yè)用氣、水、油和其他液體介質(zhì)均可使用。因而，鑒于許多可能的結(jié)構(gòu)變化，當(dāng)顆粒到選用減壓閥的時(shí)候，其中**主要的就是閥的確切性能，首先應(yīng)充分進(jìn)行檢測(cè)，以保證良好的使用效果。在檢測(cè)時(shí)，減壓閥應(yīng)能滿足如下性能要求：①在給定的彈簧壓力級(jí)范圍內(nèi)，出口壓力在**大值與**小值之間應(yīng)能連續(xù)調(diào)整，不得有卡阻和異常振動(dòng)。②對(duì)于軟密封的減壓閥，在規(guī)定時(shí)間內(nèi)不得有滲漏；對(duì)于金屬密封的減壓閥。其滲漏量應(yīng)不大于**大流量的。③出口流量變化時(shí)，其出口壓力負(fù)偏差值：直接作用式不大于20%；先導(dǎo)式不大于10%。④進(jìn)口壓力變化時(shí)，其出口壓力負(fù)偏差值：直接作用式不大于10%；先導(dǎo)式不大于5%。對(duì)于閑置不用的減壓閥，調(diào)節(jié)彈簧使其處于自由狀態(tài)。進(jìn)口和出口端應(yīng)用堵蓋封閉。常用的減壓閥的名稱、種類、技術(shù)參數(shù)見(jiàn)***章第六節(jié)中的減壓閥部分和附錄。常用減壓閥的公稱直徑和閥孔面積見(jiàn)表2-4。表2-4減壓閥閥孔面積公稱通徑DN(mm)閥座通路面積f（cm2）減壓閥的流量與流體的性質(zhì)和壓力比有關(guān)。壓力比愈小。</p><p> 對(duì)不含有氧或氧化劑的***、磷酸、醋酸、稀鹽酸等有較好的耐蝕性，同時(shí)對(duì)堿有很好的抗力。但不耐硝酸、濃***等氧化性酸的腐蝕，也不熔融金屬、硫和硫化物的腐蝕。切忌與氨接觸，它能使銅及銅合金產(chǎn)生應(yīng)力腐蝕破裂。選用時(shí)應(yīng)注意，銅合金的牌號(hào)不同，其耐腐蝕性有一定的差異。5.鋁閥門(mén)對(duì)強(qiáng)氧化性的濃硝酸的耐蝕性好，能耐有機(jī)酸和溶劑。但在還原性介質(zhì)、強(qiáng)酸、強(qiáng)堿中不耐蝕。鋁的純度越高，耐蝕性越好，但強(qiáng)度隨之下降，只能用作壓力很低的閥門(mén)或閥門(mén)襯里。6.鈦閥門(mén)鈦是活性金屬，在常溫下能生成耐蝕性很好的氧化膜。它能耐海水、各種氯化物和次氯酸鹽、濕氯、氧化性酸、有機(jī)酸、堿等的腐蝕。但它不耐較純的還原性酸，如***、鹽酸的腐蝕，切耐含有氧化劑的硝酸腐蝕。鈦閥門(mén)對(duì)孔蝕有良好的抗力。但在紅發(fā)硝酸、氯化物、甲醇等介質(zhì)中會(huì)產(chǎn)生應(yīng)力腐蝕。7.鋯閥門(mén)鋯也屬于活性金屬，它能生成緊密的氧化膜，它對(duì)硝酸、鉻酸、堿液、熔液、鹽液、尿素、海水等有良好的耐蝕性能，但不耐氫氟酸、濃***、王水的腐蝕，也不耐濕氯和氧化性金屬氯化物的腐蝕。8.陶瓷閥門(mén)以二氧化硅為主熔化燒結(jié)制成的閥門(mén)，如氧化鋯、氧化鋁、氮化硅等，除有極高的耐磨、耐溫。隔熱性能外。阿圖什立臥兩用止回閥廠家。</p><div
