選型依據(jù):
一、根據(jù)管道參數(shù)選擇電磁閥的:通徑規(guī)格(即DN )、接口方式
1 )按照現(xiàn)場(chǎng)管道內(nèi)徑尺寸或流量要求來(lái)確定通徑( DN )尺寸;
2 )接口方式, - -般> DN50要選擇法蘭接口，≤DN50則可根據(jù)用戶需要自由選擇。
二、根據(jù)流體參數(shù)選擇電磁閥的:材質(zhì)、溫度組
1 )腐蝕性流體:宜選用耐腐蝕電磁閥和全不銹鋼;食用超凈流體:宜選用食品級(jí)不銹鋼材質(zhì)電磁閥;
2 )高溫流體:要選擇采用耐高溫的電工材料和密封材料制造的電磁閥,而且要選擇活塞式結(jié)構(gòu)類型的;
3 )流體狀態(tài):大至有氣態(tài),液態(tài)或混合狀態(tài),特別是口徑大于DN25時(shí)一定要區(qū)分開(kāi)來(lái)。
