真空隔離閘閥結(jié)構(gòu)特點(diǎn)
1、設(shè)計(jì)了真空密封結(jié)構(gòu)填料室,使系統(tǒng)與大氣隔離,具有良好的環(huán)保性能。
2、選材考究,符全國(guó)內(nèi)外相關(guān)標(biāo)準(zhǔn),材料的全面質(zhì)量高。
3、密封副配對(duì)先進(jìn)合理,提高了密封性能,使用壽命長(zhǎng)。
4、啟閉件采用平行閘板雙向彈性密封,摩擦力小,啟閉輕松,維修方便,密封可靠,性能優(yōu)良。
5、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。
6、法蘭墊片采用復(fù)合材料,膨脹系數(shù)大、氣密性能好、保證系統(tǒng)與大氣隔離可靠。 真空隔離閘閥試驗(yàn)壓力
