【產(chǎn)品用途】
良工閥門(mén)集團(tuán)有限公司生產(chǎn)的J41H、J41Y 型高溫高壓截止閥適用于公稱(chēng)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(mén)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(hù)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(zhǎng)
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
