進口電動高壓調(diào)節(jié)閥
進口電動高壓調(diào)節(jié)閥產(chǎn)品概述
美國沃克(WORK)進口高壓調(diào)節(jié)閥(進口75Mpa電動調(diào)節(jié)閥、進口4500LB高壓焊接調(diào)節(jié)閥)由直行程電動執(zhí)行機構和高壓調(diào)節(jié)閥體組成。
電動籠式高壓調(diào)節(jié)閥是針對調(diào)節(jié)閥在高壓或高壓差、有嚴重汽蝕、沖蝕的嚴酷工況條件下壽命短、閥桿易斷裂、襯套易脫落嚴重問題研制開發(fā)的產(chǎn)品。
電動高壓調(diào)節(jié)閥采用籠式節(jié)流形式來分攤壓差,減少了氣蝕、沖蝕、撓流破壞,大大提高了調(diào)節(jié)閥的使用壽命,特別是用在尿素系統(tǒng)中比普通高壓閥壽命提高2-3倍。
電動執(zhí)行機構為一體化結構,內(nèi)有伺服放大器,輸入控制信號(4~20mADC或1~5VDC)
及電源即可控制閥門開度,達到對壓力、流量、液位、溫度等工參數(shù)的調(diào)節(jié)。閥體為直通式,閥芯為單導向結構,閥體流路簡單,阻力小,
電動高壓調(diào)節(jié)閥特別適用于高粘度,含有懸浮物和顆粒狀介質(zhì)流體的調(diào)節(jié),可避免結焦、粘結、堵塞。電動高壓調(diào)節(jié)閥整體具有動作靈敏、連線簡單、流量大、體積小、調(diào)節(jié)精度高等特點
