一、氣動低溫雙座調(diào)節(jié)閥--概述
 
ZMAN-16D 氣動低溫雙座調(diào)節(jié)閥是單座、雙座的變形產(chǎn)品。它與常溫不同之處在于采用長頸型上閥蓋，使填料處于常溫下工作。適用于-60～-250℃低溫壯態(tài)下的介質(zhì)（如液氧、液氮等）的調(diào)節(jié)。為確保調(diào)節(jié)精度，必須配用定位器。
二、--結(jié)構(gòu)原理
 
氣動低溫由氣動薄膜執(zhí)行機構(gòu)和耐低溫的單、雙座閥兩部分組成。由調(diào)節(jié)器來的信號壓力輸入氣動薄膜執(zhí)行機構(gòu)的氣室，產(chǎn)生推力，通過連接桿件帶動閥芯，閥芯位置的變化使閥的流通截面積變化，實現(xiàn)對介質(zhì)流量的調(diào)節(jié)。
 
三、氣--主要技術(shù)指標

四、--注意事項
 
1、應(yīng)垂直安裝于水平管道上，在特殊情況下需要水平或傾斜安裝時，一般應(yīng)加支撐。裝于保溫箱壁的園板與保溫箱壁應(yīng)平行。
2、應(yīng)安裝在靠近地面或樓板的地方，以便在于維護檢修，對裝有定位器或手輪機構(gòu)者，更應(yīng)保證觀察，調(diào)整和操作和方便。
3、一般都設(shè)置旁通管路，以便在自控系統(tǒng)發(fā)生故障或維修時切換到手動操作，不致于停止生產(chǎn)。
4、裝有手輪機構(gòu)時，也可省略旁通管路時行手動操作，還可用于限制的開度。當(dāng)停止使用時，手輪機構(gòu)必須恢復(fù)到原來空檔位置，以利自控系統(tǒng)正常進行。
5、安裝時，應(yīng)使介質(zhì)流向與閥體指示方向*。
6、在安裝前應(yīng)對管路清洗污物、焊渣。安裝后，使全開，對管路，等進行清洗及試驗各連接處的密封性。閥門調(diào)節(jié)閥調(diào)節(jié)閥閥門調(diào)節(jié)閥閥門。
