Inn sakning
Install tuahnak hmun a tlawm tikah, thimnak ah ralring tein um:
Mah cukutka valvea luannak um lonak hmual a ngeih khawh nakhnga, kharnak cunglei kha fek tein khar awkah a tlawm deuhmi hneknak kha aa bochan khawh. On le khar tikah, valve core le valve tthutnak i a kharnak cunglei cu aa tong zungzal i pakhat le pakhat an i hrolh, cucaah kharnak cunglei cu hruk a fawi, cunkutka valvekhar a nai cang, pipeline hmailei le hnulei karlak i a ummi hneknak aa dannak cu a ngan tuk, cu nih cun kharnak cunglei kha a fak deuh in a hrawh.
A sining cukutka valveglobe valve nakin a har deuh lai, a langhning zoh tikah, aa khatmi caliber kongah, gate valve cu globe valve nakin a sang deuh, cun globe valve cu a sau deuhkutka valve. Cun,kutka valvecu fung ceu le fung mui tiah ṭhen a si. Kharnak valve nih an tuah lo.
Zeitindah rian a ttuan
Globe valve an on i an khar tikah, a kai cuahmahmi stem a si, cucu, kutdonghrolh cu aa mer tikah, kutdonghrolh cu a thinghnah he aa mer lai i a cawi lai. Mah cukutka valvevalve stem nih cawi cawlcanghnak a tuah khawh nakhnga kutdonghrolh kha hler a si, cun kutdonghrolh dirhmun cu aa thleng lo.
A luan ning aa dang,kutka valvesa tlingmi on asiloah tling tein khar a herh, cu lio ah globe valve nih a tuah lo. Globe valve nih a luhnak le chuahnak lei a khiahmi a ngei, cunkutka valveluhnak le chuahnak lam a herh lo.
Cun,kutka valvedirhmun pahnih lawng a ngei: a ong dih asiloah a khar dih, cun kutka tthennak onnak le kharnak stroke cu a ngan tuk, cun onnak le kharnak caan cu a sau. Globe valve valve plate i a cawlcangh ning cu a hme deuh ngai, cun globe valve i valve plate cu a kalnak hmun pakhatkhat ah a dir kho i a luannak remhnak caah a si. Mah cukutka valvetlawmternak ca lawng ah hman khawh a si i rian dang a ngei lo.
Riantuan ning aa dannak
Globe valve cu cut-off le flow regulation caah hman khawh a si. Globe valve i ti a doh khawhnak cu a ngan deuh, cun on le khar cu a har deuh, asinain valve plate le kharnak cunglei karlak a hlatnak a tawi caah, onnak le kharnak stroke cu a tawi.
Zeicatiahkutka valvetling tein on le khar khawh lawng a si, tling tein on a si tikah, valve body channel chung i a tlawmbik a luangmi dohnak cu 0 hrawng a si, cucaah onnak le kharnak cukutka valveriantuannak a khamh tuk lai, asinain kutka tthen cu kharnak hmun he aa hlat, cun on le khar caan a sau.

Hmunhma le luannak lam
A chuahpimi thilkutka valvelam pahnih in a luannak lei cu aa khat, chiahnak ah luhnak le chuahnak lei ah a herh lo, cun a karlak cu lam pahnih in a luang kho. Globe valve cu valve pum i thal nih a langhtermi lei he aa tlak in fek tein chiah a hau, cun globe valve luhnak le chuahnak lei ah fiang tein timhtuahnak a um, cun globe valve a luannak lei cu Tuluk valve “thlennak pathum” ningin a cunglei in a tanglei tiang hman a si.
Kharnak valve cu a niam i a sang, cun lenglei in a fiangmi pipe a um i cucu phase pakhat tluk ah a um lo. Mah cukutka valvea luannak lam cu a tlarimi hri cungah a um. A stroke cukutka valvecu globe valve nakin a ngan deuh.
A luannak dohnak hmuhning in, a tling tein aa on tikah, gate valve a luannak dohnak cu a hme, cun load stop valve a luannak dohnak cu a ngan. A tlangpi in a luannak dohnak coefficientkutka valvecu 0.08~0.12 hrawng a si, onnak le kharnak thazaang cu a hme, cun a karlak cu lam hnih in a luang kho. A tlangpi globe valve hna i an luan khawhnak cu a let 3-5 in a tam deuhkutka valve hna.Onnak le kharnak cu khar khawhnak dingah hramhram in khar a hau, globe valve i a hri cu kharnak cunglei he aa tongh tikah a khar dih, cucaah kharnak cunglei a rawkmi cu a tlawm tuk, globe valve actuator chapnak caah thazaang nganpi a luan caah torque control mechanism remhnak mechanism kha biapi ah chiah a hau.
Globe valve chiahnak lam pahnih a um, pakhat cu medium cu spool tang in a lut kho, a ṭhatnak cu valve khar tikah packing cu pressure a ngei lo, cu nih cun packing riantuannak caan a sauter khawh, cun valve hmai i pipeline cu pressure tangah a um tikah packing kha a thlen khawh; A chiatnak cu valve nih a hruaimi thazaang cu a ngan, cucu a cunglei a luannak nakin a let 1 hrawng a si, valve stem i axial force a ngan, cun valve stem cu a benh a fawi.
Cucaah, hi lam hi a tlangpi in a hmetemi globe valve (DN50 asiloah a tlawm deuh) ca lawng ah aa tlak, cun DN200 cunglei globe valve nih cunglei in a luangmi thilri kha an hman. (Electric globe valves nih a tlangpi in cunglei in luh khawhnak ding caah medium kha an hman.) Cunglei in media luh khawhnak lam a chiatnak cu a tanglei luh khawhnak lam he aa ralchanh ngaingai.

Hrennak
Globe valve i a kharnak cunglei cu valve core i a hmete trapezoidal lei a si (a bik in valve core a muisam kha zoh), valve core a tlak tik ah, valve kharnak he aa tluk (pressure aa dannak a ngan ahcun, a ngaingai ti ahcun, kharnak cu a fek lo, asinain check effect cu a chia lo),kutka valvevalve core gate plate lei in khar a si, kharnak tthatnak cu globe valve tluk in a ttha lo, cun valve core cu valve kharnak he aa tlukmi globe valve bantuk in a tla lai lo.
