產(chǎn)品特點:
適用于公稱壓力PN1.6~16.0MPa,工作溫度≤-29℃~550℃的石油、化工、水力、火力電站各種系統(tǒng)的管路上,切斷或接通管路介質(zhì)。適不銹鋼閘閥用介質(zhì)為:水、油品、蒸氣、及酸、堿、氨、尿素、含硫天然氣等。
結(jié)構(gòu)特點
1、選材考究,符合國內(nèi)外相關(guān)標(biāo)準(zhǔn),材料的全面質(zhì)量高。
2、符合標(biāo)準(zhǔn)的要求,密封可靠、性能優(yōu)良、造型美觀。
3、密封副配對合理,閘板和閥座的密封面采用不同硬度的司太立(Stellite)鈷基硬質(zhì)合金堆焊而成,密封可靠、硬度高、耐磨、耐高溫、耐腐蝕、抗擦傷性能好、壽命長。
4、閥桿經(jīng)調(diào)質(zhì)及表面氮化處理,有良好的抗腐蝕性、抗擦傷性和耐磨性。
5、采用楔式彈性閘板結(jié)構(gòu),中大口徑設(shè)置推力軸承,磨擦力小,并配有撞擊手輪,啟閉輕松自如。
6、可采用各種配管法蘭標(biāo)準(zhǔn)及法蘭密封面形式,滿足各種工程需要及用戶要求。
