我公司”乾QY儀”擁有多年生產(chǎn)經(jīng)驗(yàn)蝶閥的歷史并有部分產(chǎn)品申請(qǐng)獲得了，在不斷吸引外資技術(shù)和運(yùn)用的基礎(chǔ)上獲得了市政和用戶的青睞。

蝶閥是用圓形蝶板作啟閉件并隨閥桿轉(zhuǎn)動(dòng)來(lái)開啟、關(guān)閉和調(diào)節(jié)流體通道的一種閥門。蝶閥不僅結(jié)構(gòu)簡(jiǎn)單、體積小、重量輕、材料耗用省，安裝尺寸小，而且驅(qū)動(dòng)力矩小，操作簡(jiǎn)便、迅速，并且還同時(shí)具有良好的流量調(diào)節(jié)功能和關(guān)閉密封特性，在大中口徑、中低壓力的使用領(lǐng)域，蝶閥是主導(dǎo)的閥門形式。 結(jié)構(gòu)特點(diǎn)：蝶閥具有結(jié)構(gòu)簡(jiǎn)單、體積小、重量輕、材料耗用省，安裝尺寸小，開關(guān)迅速、90°往復(fù)回轉(zhuǎn)，驅(qū)動(dòng)力矩小等特點(diǎn)，用于截?cái)?、接通、調(diào)節(jié)管路中的介質(zhì)，具有良好的流體控制特性和關(guān)閉密封性能。 公稱壓力或壓力級(jí)：PN1.0-4.0MPa、ANSI CLASS 150-300LB、JIS10-20K 公稱通徑或口徑：DN40～2000 連接方式：法蘭連接、對(duì)夾連接、對(duì)焊連接及凸耳對(duì)夾連接適用溫度：-196℃～700℃ 驅(qū)動(dòng)方式：手動(dòng)、蝸輪傳動(dòng)、氣動(dòng)、電動(dòng)、液動(dòng)、氣液聯(lián)動(dòng)、電液聯(lián)動(dòng)閥體材料：HT200、WCB、ZG1Cr18Ni9Ti、ZG1Cr18Ni12Mo2Ti、CF8(304)、CF3(304L)、CF8M(316)、CF3M(316L)。
