性能规范Property specification
用途及特点Purpose and characteristic

D373H-1OK、20K、和D343H-1OK、20K系列蝶阀的主要结构特征为对夹式和法兰式三偏心密封形式,阀座密封圈采用弹性密封和软硬兼容的多 层次密封两种结构,其密封性能可靠,确保开启时蝶板不接触密封座,: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。广泛应用于石油、化工及工业环保水处理、高层建筑、给排水等管道上。
Main configuration characteristic of D373H-10K,2OK and D343H—10K,2OK series of butterfly valve is composed of wafer and flange three eccent-ric seal,seat gasket use two config urations of elasticseal and soft hard compatible multiple layers seal,reliable hermetic capability,so as to ensure disc can't touch seal ing seat when it operation,solve the problem of seal ing seat burden unequally,prolong service life,with advantage of high temperature resistant,wearable,antisepsis etc. Ithas been widely utilized in petroleum, chemical industry and industrial environmentalprotection water treatment, high building construction,water supplying and draining pipe etc.
