高溫高壓電站截止閥主要特點及用途Chief featires and usages:
1、閥門與管路連接采用焊接式結構。
2、密封面不易磨損，擦傷，密封性能好，壽命長。
3、結構緊湊，啟閉性好、高度小、維修方便。
4、適用于水、蒸汽、油品管路上，具有耐高溫、耐高壓的特點。
1、A welding structure is used to connect the valve and pipelines.
2、The sealing face is of a good sealing property and long duration,uneasy to be worn and tubbed.
3、Compact structure,well to be opened and closed,lower in height,easy maintenance.
4、Of high-temperature and high-pressure resisting features and suitable for water,steam,oil goods pipelines.
