上裝式球閥的設計原理及功能

 DYQ340H上裝式球閥 ，包括有閥體、楔形球體
、閥座

、閥蓋
、閥fa杆gan，閥fa體ti的de側ce壁bi上shang設she有you開kai口kou向xiang上shang的de楔xie形xing球qiu體ti安an裝zhuang孔kong
，閥fa杆gan與yu楔xie形xing球qiu體ti聯lian動dong連lian接jie

，在zai閥fa杆gan下xia部bu套tao設she有you彈dan簧huang，彈dan簧huang以yi楔xie形xing球qiu體ti作zuo為wei第di一yi基ji座zuo，以yi閥fa杆gan上shang所suo設she的de凸tu台tai作zuo為wei另ling一yi基ji座zuo，在zai閥fa杆gan的de凸tu台tai的de上shang端duan與yu閥fa蓋gai之zhi間jian設she有you密mi封feng件jian，在zai閥fa蓋gai與yu閥fa體ti之zhi間jian設she有you密mi封feng墊dian片pian，所suo述shu的de密mi封feng件jian的de截jie麵mian為wei楔xie形xing，所suo述shu的de凸tu台tai或huo閥fa蓋gai上shang相xiang應ying設she有you斜xie推tui麵mian與yu密mi封feng件jian構gou成cheng楔xie形xing密mi封feng配pei合he
，斜xie推tui麵mian最zui好hao設she置zhi在zai凸tu台tai的de上shang端duan麵mian上shang

，利li用yong彈dan簧huang的de彈dan力li或huo者zhe介jie質zhi的de壓ya力li使shi用yong於yu密mi封feng閥fa杆gan與yu閥fa蓋gai間jian的de截jie麵mian為wei楔xie形xing的de密mi封feng件jian與yu密mi封feng麵mian構gou成cheng楔xie形xing密mi封feng配pei合he，利li用yong斜xie楔xie原yuan理li使shi密mi封feng麵mian更geng加jia緊jin密mi，密mi封feng效xiao果guo更geng好hao。
