一、PQ340F/H/Y偏心半球閥產(chǎn)品概述
PQ340F/H/Y偏心半球閥是一種連接方式采用法蘭，由閥體、偏心球體、主(從)動(dòng)軸、上(下)軸套、球冠、壓圈、內(nèi)(外)閥座等主要部件組成，它通過轉(zhuǎn)動(dòng)蝸輪機(jī)構(gòu)帶動(dòng)偏心曲軸旋轉(zhuǎn)90°來實(shí)現(xiàn)閥門的啟閉，起到對(duì)介質(zhì)的調(diào)節(jié)和嚴(yán)密截?cái)嗟淖饔谩?/span>
PQ340F/H/Y偏心半球閥利用偏心閥體、偏心半球和閥座、閥桿作旋轉(zhuǎn)運(yùn)動(dòng)時(shí)在共同軌跡自動(dòng)定心，關(guān)閉過程越關(guān)越緊，*達(dá)到良好的密封目的。閥門的球體和閥座*脫離，消除了密封圈的磨損，克服了傳統(tǒng)球體閥座與球體密封面始終磨損的問題，非金屬彈性材料被嵌入金屬座中，閥座金屬面受到良好的保護(hù)，其解決了工業(yè)生產(chǎn)中的漿狀、混流液體、灰塵等介質(zhì)在管道輸送中沉淀、易結(jié)垢、阻塞等問題。
