style="text-indent:25px">當(dāng)工作溫度升高時(shí)，氣動(dòng)閥門閥體的耐壓會降低。例如，公稱壓力為6.4MPa(PN64)的碳鋼控制閥，用于300℃時(shí)的耐壓為5.2MPa，用400℃時(shí)的耐壓為4.1MPa，用于450℃時(shí)的耐壓為2.9MPa。因此，控制閥公稱壓力的確定不*要根據(jù)較高工作壓力，還需根據(jù)較高工作溫度和材質(zhì)特性，而不**只需滿足公稱壓力大于工作壓力。主要種類：氣動(dòng)V型調(diào)節(jié)球閥、氣動(dòng)O型切斷球閥、扭距式汽缸球閥、電磁隔膜閥、氣動(dòng)直行程式隔膜閥、電動(dòng)閥。氣動(dòng)V型球閥用途與特點(diǎn)：用途是一種直角回轉(zhuǎn)結(jié)構(gòu)，它與閥門定位器配套使用，可實(shí)現(xiàn)比例調(diào)節(jié)；。上海單作用氣動(dòng)蝶閥廠家直銷氣動(dòng)球閥的球體是彈性的，按通道位置可分為直通式，三通式和直角式。</p><div
