發表于:2018-03-29 14:30 分享至:

 

産品用途
真空閘閥連接形式分法蘭、焊接兩種,驅動方式有手動、電動兩種。該閥門适用于工作溫度≤425℃和≤550℃,工作介質為水、蒸汽或空氣的管路上,作為啟閉裝置;尤其适用于火電廠汽機冷凝和真空負壓系統,起真空隔離密封作用。

結構特點
1、設計了真空密封結構填料室,使系統與大氣隔離,具有良好的環保性能。
2、選材考究,符全國内外相關标準,材料的全面質量高。
3、密封副配對先進合理,提高了密封性能,使用壽命長。
4、啟閉件采用平行閘闆雙向彈性密封,摩擦力小,啟閉輕松,維修方便,密封可靠,性能優良。
5、閥杆經調質及表面氮化處理,有良好的抗腐蝕性、抗擦傷性和耐磨性。
6、法蘭墊片采用複合材料,膨脹系數大、氣密性能好、保證系統與大氣隔離可靠。
