用途及特点 Usage&Feature
815、830系列蝶阀的主要结构特征为对夹式和法兰三偏心式结构,而815、830L系列的主要结构特征为阀体周边带凸耳设计成带螺孔单法兰结构。815、830系列蝶阀广泛应用于石油、化工即工业环境水处理、高层建筑,给排水等管道上。器特点为:由于采用三偏心结构。密封性能可靠,确保开启时蝶阀不接触密封座,消除了密封座不均匀负载,延长了使用寿命,确保可靠的密封性能,具有耐高温、耐磨损、耐腐蚀等优点。
Main configuration characterisic of 812,810 series of butterfly valve is composed of wafer and flange three eccentricity,then man configuration characteristic of 815,830l series butterfly valve is dege of body with protruding ears and single flange configuration with screw.815,830 series of butterfly valve has been widely utilized in petroleum,chemain characteristic is :due to use three eccentric con figuration,hermetic capability reliably,which ensure disc never touch sealingseat when it start,solve the problem of hermetical eat burden unequally,prolong service life,and ensure reliable hermetic capability with aduatage of high tem perature resistant,werable,antisepsis etc.
