一、進口波紋管密封調(diào)節(jié)閥概述

進口波紋管密封調(diào)節(jié)閥（Bellows seal control valve）是一種頂導向結(jié)構的調(diào)節(jié)閥，閥體結(jié)構緊湊，流體通道呈S流線型，壓降損失小，流量大，可調(diào)范圍廣。

    上閥蓋采用波管紋密封結(jié)構，可*消除工藝介質(zhì)從閥桿運動間隙向外泄漏的可能性，這是波紋管密封閥的顯著特點之一。由于波紋管元件本身變形性和*的抗老化性，這種調(diào)節(jié)閥*克服了填料密封閥通常存在的填料老化和溫差敏感等弱點。其次，采用波紋管—填料雙重密封結(jié)構，安全可靠性更好。

    因此，它在劇毒，強腐蝕性，放射性等稀有特殊介質(zhì)的自動控制系統(tǒng)中得到廣泛應用。

    閥芯導向面積大，抗振性好，配用多彈簧式薄膜執(zhí)行機構，其結(jié)構緊湊，輸出力大。

三、進口波紋管密封調(diào)節(jié)閥參數(shù)表

進口調(diào)節(jié)閥control valve（美國VTON威盾）是由電動執(zhí)行機構或氣動執(zhí)行機構、自力式感應與閥體兩部分共同組成，根據(jù)調(diào)節(jié)部位信號，自動調(diào)節(jié)閥門的開度，從而達到介質(zhì)流量、壓力和液位的閥門。調(diào)節(jié)閥分電動調(diào)節(jié)閥、氣動調(diào)節(jié)閥和自力式調(diào)節(jié)閥等。
