【產(chǎn)品用途】
集團(tuán)生產(chǎn)的J41H、J41Y 型高溫高壓截止閥適用于公稱壓力150LB~2500LB,工作溫度為570℃的石油、化工 、水力 、火力電站各種系統(tǒng)的管路中,切斷或接通管路介質(zhì)。
【產(chǎn)品特點(diǎn)】
1、閥門中腔采用壓力自緊式密封結(jié)構(gòu),密封性能越好。支管兩端為焊接結(jié)構(gòu)。焊接坡口可按標(biāo)準(zhǔn)或用戶要求配接
2、閥瓣、閥座的密封面采用司太立鈷基硬質(zhì)合金堆焊而成,耐磨、耐高溫,抗擦傷性能好、使用壽命長
3、閥桿經(jīng)調(diào)質(zhì)和表面氮化處理,有良好的搞腐蝕性和抗擦傷性。
4、閥蓋填料函深度合理,填料加緩蝕劑,密封可靠
【執(zhí)行標(biāo)準(zhǔn)】
設(shè)計(jì)標(biāo)準(zhǔn):ASME B16.34
結(jié)構(gòu)長度:SME B16.10
試驗(yàn)與檢驗(yàn):API 598
