ZMAP氣動薄膜低(di)溫(wen)單座調節閥(fa)—ZMAN氣動薄膜低(di)溫(wen)雙(shuang)座調節閥(fa)
氣動薄膜低溫(wen)調(diao)(diao)(diao)節(jie)閥(fa)是單座、雙座調(diao)(diao)(diao)節(jie)閥(fa)的(de)(de)變形產品(pin)。它與常溫(wen)不同(tong)之處(chu)在于采(cai)用(yong)長(chang)頸型上閥(fa)蓋，使填料處(chu)于常溫(wen)下工作。氣動薄膜低溫(wen)調(diao)(diao)(diao)節(jie)閥(fa)適用(yong)于-60～-250℃低溫(wen)壯(zhuang)態下的(de)(de)介質（如液(ye)氧、液(ye)氮等(deng)）的(de)(de)調(diao)(diao)(diao)節(jie)。為(wei)確保調(diao)(diao)(diao)節(jie)精度，必(bi)須(xu)配用(yong)定位器。

【ZMAP、ZMAN氣動(dong)薄膜低溫調節(jie)閥-結構原理】
氣動低溫調節閥由氣動薄膜執行機構和耐低溫的單、雙座調節閥兩部分組成。
由調(diao)節(jie)器來(lai)的(de)信號壓力輸(shu)入氣動薄膜執行機構(gou)的(de)氣室，產(chan)生推力，通過連接桿件(jian)帶動閥芯(xin)，閥芯(xin)位置的(de)變化使閥的(de)流(liu)通截面積變化，實(shi)現對介質流(liu)量的(de)調(diao)節(jie)。
