Q41H金屬硬密封球閥特點(diǎn):
1、手動部分可采用鋼板壓制的手柄或不銹鋼鑄造的手柄。手柄設(shè)有限位結(jié)構(gòu),在閥門開啟、關(guān)閉的位置設(shè)定限位,當(dāng)閥門使用在關(guān)鍵裝置上時(shí),限位塊上設(shè)有鎖孔可鎖定開關(guān)位置避免誤操作。手柄上有明顯地開和關(guān)標(biāo)識。
2、閥桿采用A182F(1Cr13)整體鍛造并調(diào)制處理,硬度達(dá)到HB220~250。閥桿通過平鍵或花鍵或方契與手柄連接,通用性強(qiáng),拆裝方便。閥桿設(shè)有防吹出結(jié)構(gòu)。
3、閥門的填料選用編結(jié)、柔性石墨密封圈或四氟烯密封圈,使得閥桿在一定的潤滑情況下實(shí)現(xiàn)可靠的密封。
4、根據(jù)需要,球閥可設(shè)計(jì)成防靜電結(jié)構(gòu),在球體與閥桿、閥桿與閥體之間設(shè)置導(dǎo)電彈簧,避免靜電打火點(diǎn)燃易燃物質(zhì),確保系統(tǒng)安全。
5、密封副形式多樣。根據(jù)不同工況可選用軟密封、硬密封、防火閥座等結(jié)構(gòu);DN150以下為浮球形式,DN200以下為固定球形式。
6、球閥閥座處可設(shè)置輔助密封結(jié)構(gòu),在閥座和閥桿部位加裝注脂閥,緊急情況下可暫時(shí)密封,并可根據(jù)需要加長閥桿以適宜埋地鋪設(shè)得場所
