Kum 30s ah,butterfly valveUSA ah an rak ser, 50s ah Japan ah an rak luhpi, cun 60s ah Japan ah an rak hman, cun 70s hnu ah Tuluk ram ah an rak thanh. Atu lio ah, vawleicung ah DN300 mm cunglei butterfly valve pawl nih gate valve pawl kha zaangfah tein an thlen hna. he tahchunh ahcunkutka valves, butterfly valves cu on le khar caan tawite, riantuannak thazaang tlawmte, chiahnak hmun tlawmte le ritnak a tlawmmi an ngei. DN1000 tahchunhnak ah lak ahcun, butterfly valve cu 2T hrawng a si, cun gate valve cu 3.5T hrawng a si, cun butterfly valve cu mawtaw mawnghnak thilri phunphun he fonh a fawi, a fekmi le zumhawktlakmi a si.
Rubber seal nih a chuahpimi thatlonakbutterfly valvecu throttling caah hman tikah, hman ningcang lo ruangah cavitation a chuak lai, cu nih cun rubber tthutdan kha a thleh lai i a hrawh lai. Nai kum hna ah, Tuluk nih thir in kharmi butterfly valve zong a ser, cun naite kum hna ah, Japan zong nih cavitation a doh khomi, a hninh tlawmmi le aw a tlawmmi comb-shaped butterfly valve zong a ser.
A tlangpi in kharnak tthutdan riantuan caan cu a ttha mi thil sining tangah rubber caah kum 15-20 le thir caah kum 80-90 a si. Sihmanhsehlaw, zeitindah a dikthliar in thim ding a si timi cu riantuannak dirhmun nih a herhmi cungah aa hngat.
A onnak karlak pehtlaihnakbutterfly valvecun a luan ning cu a tlangpi in a tlarimi le aa tlukmi a si. A luan ning uk khawhnak caah hman a si ahcun, a luan ning sining zong cu pipe luannak doh khawhnak he aa naih ngai, cu bantuk cu pipeline pahnih ah chiahmi valve hna i an diameter le an muisam aa khat, cun pipeline sunghnak coefficient aa dang, cun valve a luan ning zong aa dang tuk lai.
Valve cu a nganmi throttling dirhmun ah a um ahcun, valve plate hnulei cu cavitation a chuak kho, cun valve rawh khawhnak a um, cucaah 15° lenglei ah hman a si tawn.
Butterfly valve cu a laifang a ongmi ah a um tikah, a ongmi muisam cuvalvepum le butterfly plate hmailei donghnak cu valve shaft cung ah aa hngat, cun a kap hnih nih dirhmun dangdang an ser, butterfly plate hmailei donghnak cu khatlei ah a luangmi ti lei ah aa chawk, cun a dang lei cu a luangmi ti lei he aa ralchanh in aa chawk, cucaah, valve pum cu khatlei ah a um i valve plate nih valve a ser lo, a dang lei he aa lo in aa on throttle hole bantuk a ongmi, nozzle lei cu throttle lei nakin a rang deuh ngai, cun throttle lei valve tangah a ttha lomi hneknak a chuak lai, cun rubber seal cu a tla tawn.
Butterfly valve riantuannak thazaang cu, valve onnak le onnak lei aa dang caah, a man aa dang, cun a tlarimi butterfly valve, a hlei in a nganmi valve, ti thuknak ruangah, valve shaft lu cunglei le tanglei karlak i aa dannak nih a chuahtermi thazaang cu zeirel loin um khawh a si lo. Cun, valve luhnak lei ah elbow an chiah tikah, a tliknak a chuak i, torque a karh. Valve cu a laifang ah a um tikah, ti a luannak torque riantuannak ruangah riantuannak thilri cu amah tein aa khar a hau.
