z61y-鍛鋼閘閥
鍛鋼閘(zhá)閥有三種閥蓋設計(jì)，第一種是(shì)螺栓型閥蓋，通(tōng)過凹凸面(miàn)連接，采用不鏽(xiù)鋼帶(dài)與柔性石(shí)墨纏(chán)繞墊(niàn)片，按需求(qiú)也可采用環連(lián)接，第(dì)二種(zhǒng)是焊接型(xíng)閥蓋(gài)，通過螺紋(wén)密(mì)封後焊接，按需求也可(kě)直接(jiē)采用(yòng)剛性焊接(jiē)，第三種是(shì)自密(mì)封閥(fá)蓋，通過螺(luó)紋(wén)與自密(mì)封閥蓋連(lián)接。
鍛(duàn)鋼(gāng)閘(zhá)閥的結構(gòu)設計(jì)與規範：
鍛鋼閘(zhá)閥制造按(àn)api 602,bs5352,ansi b16.34.
試驗與(yǔ)驗(yàn)收按(àn)api 598,标識(shí)按(àn)照(zhào)mss sp-25.
結構(gòu)型式如下(xià)：
1.全通(tōng)徑或(huò)縮徑；
2.明(míng)杆(gǎn)帶支架；
3.兩(liǎng)端自動調心(xīn)的填料壓套(tào)；
4.用纏繞式墊(niàn)片的螺栓型(xíng)閥蓋(gài)、螺紋密封焊接型閥蓋，或自密封(fēng)閥蓋
5.本體倒密封(fēng)；
6.承插(chā)焊(hàn)接ansi/asme b16.11;
7.螺紋端(npt端(duān))按ansi/asme b1.20.1。
