Forged Steel Bellow Seal Globe valve refers to the corrugated pipe valve forged steel globe valve.
鍛鋼波紋管截止閥主要適用于火力電站各種系統(tǒng)的管路上,切斷或接通管路介質(zhì)。適用介質(zhì):水、蒸氣等非腐蝕性介質(zhì)。鍛鋼波紋管截止閥與其他閥門產(chǎn)品相比的特點是高溫高壓,*的自密封設(shè)計,壓力越高,密封越可靠。由于性能技術(shù)特性、工況的特殊使產(chǎn)品也形成了其他產(chǎn)品所替代不了的特點。
鍛鋼波紋管截止閥有二種閥蓋設(shè)計形式。*種是螺栓式閥蓋,按這種形式設(shè)計的閥門,其閥體與閥蓋用螺栓螺母連接,纏繞式墊片(316夾柔性石墨制造)密封??蛻粲刑厥庖髸r也可采用金屬環(huán)連接。第二種設(shè)計形式是焊接式閥蓋,按這種形式設(shè)計的閥門,其閥體與閥蓋用螺紋連接,全焊密封。客戶有特殊要求時也可采用全焊透連接。
進口鍛鋼波紋管截止閥產(chǎn)品特征:
1、高溫、高壓介質(zhì)的管路或裝置上宜選用截止閥。如火電廠、核電站,石油化工系統(tǒng)的高溫、高壓管路上。
2、管路上對流阻要求不嚴的管路上。即對壓力損失考慮不大的地方。
3、小型閥門可選用針閥、儀表閥、取樣閥、壓力計閥等。
4、有流量調(diào)節(jié)或壓力調(diào)節(jié),但對調(diào)節(jié)精度要求不高,而且管路直徑又比較小,如公稱通經(jīng)≤50mm的管路上,宜選用。
5、合成工業(yè)生產(chǎn)中的小化肥和大化肥宜選用公稱壓力PN160公稱壓力16MPa或PN320公稱壓力32MPa的高壓角式截止閥或高壓角式節(jié)流閥。
6、氧化鋁拜耳法生產(chǎn)中的脫硅車間、易結(jié)焦的管路上,易選用閥體分開式、閥座可去處的、硬質(zhì)合金密封副的直流式截止閥或直流式節(jié)流閥。
7、鍛鋼波紋管截止閥結(jié)構(gòu)合理、密封可靠、性能優(yōu)良、造型美觀;
密封面堆焊Co硬質(zhì)合金、耐磨、耐腐、抗磨擦性能好、使用壽命長;
閥桿調(diào)質(zhì)及表面氮化處理,有良好的抗腐和抗磨擦性能;
雙重密封,性能更可靠;
閥桿升降位置指示更直觀;
零件材料,法蘭和對焊尺寸可根據(jù)實際工況或用戶要求合理選配,滿足各種工程需要。
