一、進(jìn)口氣動(dòng)保溫調(diào)節(jié)閥概述

     進(jìn)口氣動(dòng)保溫調(diào)節(jié)閥（Pneumatic insulation jacket regulating valve）具有同單座調(diào)節(jié)閥相同的性能，主要應(yīng)用在保溫場(chǎng)合。當(dāng)工藝介質(zhì)的結(jié)晶溫度低于環(huán)境溫度或流體溫度降低，造成粘度增加或流體出現(xiàn)凝固時(shí)，這時(shí)在調(diào)節(jié)閥體和上閥蓋處增設(shè)蒸汽保溫夾套裝置，使工藝過(guò)程按要求進(jìn)行下去。
