本系列NKZ44H真空隔離法蘭閘閥連接形式分法蘭、焊接兩種，驅(qū)動方式有手動、電動兩種。該真空隔離閘閥適用于工作溫度≤425℃和≤550℃，工作介質(zhì)為水、蒸汽或空氣的管路上，作為啟閉裝置；尤其適用于火電廠汽機(jī)冷凝和真空負(fù)壓系統(tǒng)，起真空隔離密封作用。
NKZ44H真空隔離法蘭閘閥結(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*合理，提高了密封性能，使用壽命長。
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。
