一、概述Outline
QJ(D/S)V、QJ(D/S)VY型精小型氣動(dòng)V型調(diào)節(jié)球閥由氣動(dòng)活塞式執(zhí)行機(jī)構(gòu)和帶V型切口的部分球面形的整體式球閥組成。屬旋轉(zhuǎn)類調(diào)節(jié)球閥。
氣動(dòng)V型調(diào)節(jié)球閥以壓縮空氣為動(dòng)力源。接受控制系統(tǒng)來的4—20mA DC(0—10mA DC)訊號(hào)，通過電氣轉(zhuǎn)換或電—?dú)?a href="http://m.twlemb.com/htmlmodel/cpxx/15770120.html" class="keyword_inherit" name="keyword_inherit" target="_blank">閥門定位器將電信號(hào)轉(zhuǎn)化成閥門動(dòng)作所需要的氣信號(hào)，對(duì)調(diào)節(jié)球閥進(jìn)行調(diào)節(jié)。
氣動(dòng)V型調(diào)節(jié)球閥，其流道通暢，流量系數(shù)大，可調(diào)范圍大，密封性能好。其帶V型切口的閥芯，對(duì)閥座具有良好的剪切作用，使該產(chǎn)品適用于石油化工、造紙、污水處理及冶金等行業(yè)，對(duì)含有纖維和顆粒的懸濁液介質(zhì)進(jìn)行流量控制，特別適用于制漿、造紙生產(chǎn)過程中的紙漿、白水、黑液、白液等懸浮顆粒流體及濃濁狀流體介質(zhì)的自動(dòng)調(diào)節(jié)。
氣動(dòng)活塞式執(zhí)行結(jié)構(gòu)可分為單作用和雙作用兩種。雙作用使用在失電或失氣時(shí)，閥門處于失電或失氣時(shí)，閥門處于原始極限位置(全開或全閉)，以確保生產(chǎn)過程處于**位置。
