側(cè)裝式偏心半球閥產(chǎn)品概述:
側(cè)裝式偏心半球閥是利用偏心閥體,偏心球體和閥座,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(guò)程中越關(guān)越緊,*達(dá)到良好的密封目的。偏心半球閥,硬密封偏心球閥,不銹鋼偏心球閥的球體和閥座*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(wèn)題,非金屬?gòu)椥圆牧媳磺度虢饘僮校y座金屬面受到良好的保護(hù)。手偏心半球閥,硬密封偏心球閥,不銹鋼偏心球閥特別適用于鋼鐵業(yè),鋁業(yè),纖維,微小固體顆粒,紙漿,煤灰,石油氣等介質(zhì)。
產(chǎn)品特點(diǎn):
1、其結(jié)構(gòu)采用偏心契緊原理通過(guò)傳動(dòng)機(jī)構(gòu)達(dá)到閘緊、調(diào)節(jié)、關(guān)閉的目的,密封副是金屬面環(huán)帶硬面接觸密封,雙偏心結(jié)構(gòu)在開啟時(shí)閥芯位于藏球室內(nèi),流通截面大,且閥門不被沖刷,關(guān)閉時(shí)閥芯不被沖刷,開啟時(shí)閥芯球面沿閥座漸進(jìn),有效地切除結(jié)垢障礙,實(shí)現(xiàn)可靠密封。它對(duì)兩相混流易結(jié)垢固體析出的混流輸送特別有效。
2、閥門的半球用雙金屬,母材上堆焊不同的合金,閥座也作相應(yīng)堆焊經(jīng)特殊的處理,密封面組合成防腐、耐磨、高強(qiáng)度等各種類型,滿足不同場(chǎng)合需求。
3、密封嚴(yán)密、輸送有害氣體可達(dá)零泄露。
4、密封副的閥芯留有補(bǔ)償量、當(dāng)閥做磨損后,關(guān)閉時(shí)再轉(zhuǎn)動(dòng)少許,任能可靠密封,延長(zhǎng)了使用壽命。此外,用戶將壓緊螺母擰掉,調(diào)整或更換后閥座仍可用,避免了閥門密封失效后,整臺(tái)報(bào)廢的弊端。
