安全閥的反作用力是可以計(jì)算的。四、調(diào)節(jié)閥的安裝（1）調(diào)節(jié)閥的安裝位置應(yīng)滿足管道系統(tǒng)（工藝流程）設(shè)計(jì)要求，并應(yīng)盡量靠近與其相關(guān)的就地指示儀表（一次表），盡量接近測(cè)量元件所在位置，以便于在手動(dòng)操作旁通閥時(shí)，能觀察到一次儀表數(shù)值。調(diào)節(jié)閥應(yīng)盡量正立垂直安裝于水平管道上，特殊情況下才可水平或傾斜安裝，但須加支撐。（2）為便于操作和維修，減少占地，調(diào)節(jié)閥組應(yīng)盡量布置在地面靠墻、靠設(shè)備或平臺(tái)等易于接近的地方。與平臺(tái)或地面的凈空應(yīng)不小于250mm。（3）調(diào)節(jié)閥應(yīng)安裝在環(huán)境溫度不高于60℃且不低于-40℃的場(chǎng)所，應(yīng)遠(yuǎn)離振動(dòng)器，盡量避免火災(zāi)危險(xiǎn)的影響。（4）調(diào)節(jié)閥一般都要安裝旁路與旁通閥。旁通閥主要是當(dāng)調(diào)節(jié)檢修停用時(shí)作調(diào)節(jié)流量之用，故一般應(yīng)選用截止閥。但當(dāng)旁通閥DN≥l5Omm時(shí)，也可選用閘閥。調(diào)節(jié)前后的切斷閥宜先用閘閥，因其阻力小，關(guān)閉嚴(yán)密。一般調(diào)節(jié)閥前后有大小頭，應(yīng)緊接調(diào)節(jié)閥安裝。為了在調(diào)節(jié)閥檢修時(shí)將兩切斷閥之間管道泄壓、排凈，一般可在調(diào)節(jié)閥入口側(cè)上游的切斷閥之間的管道的比較低點(diǎn)設(shè)排液閥DN＝15mm。另外，宜在入口切斷閥后、調(diào)節(jié)閥前加設(shè)過(guò)濾器（調(diào)節(jié)閥DN＜25mm者，必須加過(guò)濾器）。廬江溢流泄壓閥門廠家電話在不限制閘閥整體自由變形的情況下，與流體壓力相比，因熱產(chǎn)生的變形較大，而應(yīng)力較小。</p><div
