Globe valve, gate valve, butterfly valve, check valve le ball valve hna hi nihin pipe system phunphun ah a herhmi uknak thilri an si dih. Valve kip cu an muisam, an dirhmun le an hmannak hmanh ah an i dang. Sihmanhsehlaw, globe valve le gate valve cu an muisam ah aa lonak tlawmpal an ngei, cun cu caan te ah cun pipeline chung i tthencheunak rian an ngei, cucaah an pahnih in buaiter awkah valve he pehtlaihnak a ngei lomi hawikom tampi an um lai. A ngaingai ti ahcun, ttha tein na zoh ahcun, globe valve le gate valve karlak i aa dannak cu a ngan ngai rih.
- Inn sakning
Installation hmun tlawmte lawng a um ahcun, thimnak ah ralrin a herh:
Gate valve cu a tlawm deuhmi hneknak cungah i hngatchan in kharnak cunglei he fek tein khar khawh a si, cucaah a luannak um lonak tthatnak kha hmuh khawh a si. On le khar tikah, valve spool le valve tthutnak kharnak cunglei cu pakhat le pakhat an i tong zungzal i pakhat le pakhat an i hrolh, cucaah kharnak cunglei cu hruk a fawi, cun gate valve cu khar a naih tikah, pipeline hmailei le hnulei karlak i hneknak aa dannak cu a ngan tuk, cu nih cun kharnak cunglei cu a rawk chin lengmang.
Gate valve dirhmun cu globe valve nakin a har deuh lai, a langhnak zoh tikah, aa khatmi caliber ahcun, gate valve cu globe valve nakin a sang deuh, cun globe valve cu gate valve nakin a sau deuh. Cun, gate valve cu a ceumi rod le a muimi rod tiah tthen a si. Vawlei cung valve cu a si lo.
- Rian
Globe valve cu on le khar a si tikah, a kai cuahmahmi stem phun a si, cucu, kut kedan cu aa mer, cun kut kedan nih valve stem he aa mernak le cawinak cawlcanghnak a tuah lai. Gate valve cu kutdonghrolh kha a merter lai, cucaah a hnah nih cawi cawlcanghnak a tuah lai, cun kutdonghrolh dirhmun cu aa thleng lai lo.
A luan ning aa dang, gate valve pawl cu tling tein asiloah tling tein khar a hau, globe valve pawl nih cun an khar lo. Globe valve nih a hleiin luhnak le chuahnak lei a ngei, cun gate valve nih cun luhternak le chuahnak lei a herh lo.
Cun, gate valve cu state pahnih lawng a tling tein a on asiloah a tling tein a khar, gate onnak le kharnak stroke cu a ngan tuk, onnak le kharnak caan a sau. Globe valve i valve plate cawlcanghnak stroke cu a hme deuh ngai, cun globe valve i valve plate cu a luan ning thlennak caah hmun pakhatkhat ah a dir kho. Gate valve cu tthencheunak ca lawng ah hman khawh a si i rian dang a ngei lo.
- Hmuhsaknak
Globe valve cu a tawinak le a luan ning uknak 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 cu kharnak cunglei in a tawi caah, onnak le kharnak stroke cu a tawi.
Zeicatiah gate valve cu tling tein on khawh le tling tein khar khawh a si caah, tling tein on a si tikah, valve body channel chung i a ummi medium flow doh khawhnak cu 0 hrawng a si, cucaah gate valve on le khar cu riantuannak a khamh tuk lai, asinain gate plate cu kharnak cunglei in a hlat, cun on le khar caan cu a sau.
- Hmunhma le luannak lam
Gate valve cu lam pahnih in a luangmi nih a chuahpimi thil cu aa khat, cun chiahnak ah a luhnak le chuahnak lei ah a herh lo, cun a karlak cu lam pahnih in a luang kho. Globe valve cu valve pum thal hngalh khawhnak lamhruainak he fek tein chiah a hau, cun globe valve luhternak le chuahnak lamthluan kongah fiang tein phunglam a um, cun Tuluk ram ah globe valve “three to” a luannak lamthluan cu a cunglei in a tanglei tiang a si.
Globe valve cu a niam i a sang, cun lenglei in a fiangmi pipe pawl cu phase level ah an um lo. Kutka valve runner cu a tlarimi hri ah a um. Gate valve stroke cu globe valve nakin a ngan deuh.
A luannak dohnak hmuhning in, gate valve a luannak dohnak cu a tling tein a on tikah a hme, cun load stop valve a luannak dohnak cu a ngan. Gate valve sawhsawh i a luannak doh khawhnak coefficient cu 0.08~0.12 hrawng a si, onnak le kharnak thazaang cu a hme, cun a karlak cu lam pahnih in a luang kho. A tlangpi in kharnak valve hna i an luan khawhnak cu gate valve hna nakin a let 3-5 in a tam deuh. On le khar tikah, kharnak hmuh khawhnak ding caah kharnak kha hramhram in tuah a herh, globe valve i valve spool cu kharnak cunglei he aa tong dih tikah lawng a si, cucaah kharnak cunglei a rawhnak cu a tlawm tuk, zeicahtiah a biapi bikmi thazaang a luannak nih actuator kha chap a herh.
Globe valve cu chiahnak lam pahnih a ngei, pakhat cu valve spool tang in medium a luh khawh, a ṭhatnak cu valve khar a si tikah, thilri chiahnak cu hneknak tangah a um lo, thilri chiahnak caan sauh khawh a si, cun thilri chiahnak thlennak rian cu valve hmai pipeline chung i hneknak tangah tuah khawh a si; a chiatnak cu valve nih a hruaimi thazaang cu a ngan, cucu a cunglei a luangmi nak in a let 1 hrawng a si, cun valve stem i axial force a ngan, cun valve stem cu bengh a fawi.
Cucaah, hi lam hi a tlangpi in a hmete mi globe valve (DN50 asiloah a tlawm deuh) ca lawng ah aa tlak, cun DN200 cunglei globe valve pawl cu cunglei in a luangmi media lam caah thim an si. (Electric shut-off valves nih a tlangpi in cunglei in luh khawhnak ding caah medium kha an hman.) Cunglei in media a luh ning a chiatnak cu a tanglei in a luh ning 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 a hnulei thil sining cu a chia lo), gate valve cu valve core lei ah a khar, plate plate kharnak tthatnak cu vawlei cung valve tluk in a ttha lo, cun valve core cu vawlei cung valve bantuk in a tla lai lo.
