由計(jì)算出的安全閥的定壓值決定彈簧或杠桿的調(diào)壓范圍，根據(jù)使用介質(zhì)決定安全閥的材料和結(jié)構(gòu)形式，根據(jù)安全閥的排放量計(jì)算出安全閥的噴嘴截面積或噴嘴直徑，以選取安全閥型號(hào)和個(gè)數(shù)。彈簧直接載荷式安全閥的工作壓力等級(jí)如表2-5所示，共有五種工作壓力級(jí)。選擇時(shí)，除注明產(chǎn)品型號(hào)、名稱、介質(zhì)、溫度外，還應(yīng)注明彈簧的壓力級(jí)別。表2-5彈簧安全閥工作壓力級(jí)公稱壓力PN/MPa工作壓力/MPaρⅠρⅡρⅢρⅣρⅤ＞～＞～＞16～20＞～＞～＞20～25＞～＞～＞～＞～＞～＞～＞～＞22～25＞～＞～＞～＞～＞～＞～＞10～13＞25～29＞～＞～＞～＞～＞～＞～10＞13～16＞29～32安全閥的進(jìn)口和出口分別處于高壓和低壓兩側(cè)，所以連接法蘭也相應(yīng)采用不同的壓力等級(jí)，如表2-6所示。表2-6安全閥進(jìn)出口法蘭壓力級(jí)MPa安全閥公稱壓力進(jìn)口法蘭壓力級(jí)出口法蘭壓力級(jí)當(dāng)介質(zhì)經(jīng)由安全閥排放時(shí)，其壓力降低，體積膨脹，流速增加，故安全閥的出口通徑大于進(jìn)口通徑。對(duì)于微啟式安全閥，其出口通徑可等于進(jìn)口通徑，這是因其排量小，又常用于液體介質(zhì)。而全啟式安全閥的排量大，多用于氣體介質(zhì)，故其出口通徑一般比公稱通徑大一級(jí)。進(jìn)出口通徑按表2-7選用。新疆控制閥門價(jià)格阿勒泰暗桿軟密封閘閥的價(jià)格。</p><div

閥門常見問(wèn)題編輯調(diào)節(jié)閥為什么雙密封閥不能當(dāng)作切斷閥使用？雙座閥閥芯的優(yōu)點(diǎn)是力平衡結(jié)構(gòu)，允許壓差大。而它突出的缺點(diǎn)是兩個(gè)密封面不能同時(shí)良好接觸，造成泄漏大。如果把它人為地、強(qiáng)制性地用于切斷場(chǎng)合，顯然效果不好，即便為它作了許多改進(jìn)（如雙密封套筒閥），也是不可取的。調(diào)節(jié)閥為什么雙座閥小開度工作時(shí)容易振蕩？對(duì)單芯而言，當(dāng)介質(zhì)是流開型時(shí)，閥穩(wěn)定性好；當(dāng)介質(zhì)是流閉型時(shí)，閥的穩(wěn)定性差。雙座閥有兩個(gè)閥芯，下閥芯處于流閉，上閥芯處于流開，這樣，在小開度工作時(shí)，流閉型的閥芯就容易引起閥的振動(dòng)，這就是雙座閥不能用于小開度工作的原因所在。什么直行程調(diào)節(jié)閥防堵性能差，角行程閥防堵性能好？直行程閥閥芯是垂直節(jié)流，而介質(zhì)是水平流進(jìn)流出，閥腔內(nèi)流道必然轉(zhuǎn)彎倒拐，使閥的流路變得相當(dāng)復(fù)雜（形狀如倒S型）。這樣，存在許多死區(qū)，為介質(zhì)的沉淀提供了空間，長(zhǎng)此以往，造成堵塞。角行程閥節(jié)流的方向就是水平方向，介質(zhì)水平流進(jìn)，水平流出，容易把不干凈介質(zhì)帶走，同時(shí)流路簡(jiǎn)單，介質(zhì)沉淀的空間也很少，所以角行程閥防堵性能好。為什么角行程類閥的切斷壓差較大？角行程類閥的切斷壓差較大，是因?yàn)榻橘|(zhì)在閥芯或閥板上產(chǎn)生的合力對(duì)轉(zhuǎn)動(dòng)軸產(chǎn)生的力矩非常小。</p><p>
