Gate valve sawhsawh nih a tlangpi in a fekmi kharmi gate valve kha a chim duhmi a si. Hi capar nih hin nem tein kharmi kutka valve le a tlangpi in kutka valve karlak i aa dannak kha fiang tein a hlathlai. A phi na lungtlin ahcun, VTON kha kutdonghrolh pe.
A tawinak in chim ahcun, a nemmi a nemmi kutka valve hna cu thir le thir a si lomi karlak i kharnak an si, cu hna cu nylon\tetrafluoroethylene tibantuk an si, cun a harmi kharnak kutka valve hna cu thir le thir karlak i kharnak an si;
Nem tein kharmi kutka valve le a harmi kutka valve nih valve tthutnak kharnak thilri kha a chim duhmi a si. A harmi kharnak hna cu valve tthutnak thilri hna he ttha tein an ser hna i valve core (ball) he aa tlak ning tein an ser hna, a tlangpi in thir le dar. A nemmi kharnak nih cun valve tthutnak ah aa khumhmi kharnak thilri pawl kha thir a si lomi thilri tiah a ti. Zeicatiah a nemmi kharnak thilri hna nih a tthawngmi thil pakhatkhat an ngeih caah, a dikthliar in tuah khawhnak a herhmi cu a harmi kharnak thilri hna nakin a niam deuh. Ramdang in luhpi mi nem tein kharmi kutka valve le ramdang in luhpi mi har in kharmi kutka valve karlak i aa dannak kha langhter awkah VTON sining kha kan chim.
1. Hrennak thilri
1. An pahnih i an kharnak thilri cu aa dang.Nem tein kharmi kutka valvea tlangpi in rubber asiloah polytetrafluoroethylene in sermi an si. A fekmi kharmi kutka valve pawl cu thir bantuk thir in sermi an si.
2. Soft seal: Seal pahnih cu khatlei ah thir thilri in sermi a si i khatlei ah thir a si lomi thilri in sermi a si, cucu “soft seal” tiah auhmi a si. Hi bantuk kharnak nih hin kharnak ttha a ngei, asinain lumnak sang ah a tei kho lo, hruk a fawi, cun thilri ttha lo a ngei. Tahchunhnak ah: thir hri; thir tetrafluoroethylene, tbk. Tahchunhnak ah, ramdang in luhpi mi a nemmi tthutdan kharnakkutka valve of VTON cu a tlangpi in 100°C nak tlawm deuh lumnak ah hman a si, cun a tam deuh cu khaan lumnak ti caah hman a si.
3. Hard seal: Seal pahnih cu thir thilri asiloah a dang a har deuhmi thilri in a kap hnih in sermi a si, cucu “hard seal” tiah auhmi a si. Hi bantuk kharnak nih hin kharnak riantuannak a ttha lo, asinain lum tuk, hruk-aih a tuar khawh i seh thiamnak ttha a ngei. Tahchunhnak ah: thir thir; thir dar; thir graphite; thir cawhmi thir; (hika thir cu thir thletmi zong a si kho, thir thletmi, alloy thir zong a cunglei ah a ummi, thletmi thir zong a si kho). Tahchunhnak ah, VTON i ramdang in luhpi mi thir thir kutka valve cu meikhu, gas, chiti le ti tbk caah hman khawh a si.
2. Inn saknak thiamnak
Sehzung sernak riantuannak pawngkam cu a har ngai, cu hna lakah tampi cu a niam tukmi lumnak le a niam tukmi hneknak an si, a nganmi ralchanhnak le a tthawngmi rawhnak a ngeimi thilri hna he. Atu cu thiamnak a tthancho cang caah, a fekmi kharmi kutka valve pawl cu mi tampi nih an thanh cang.
Thir karlak i a harmi pehtlaihnak kha ruah chih a hau. A ngaingai ti ahcun, a fekmi kharmi kutka valve cu a nemmi kharmi he aa khat, zeicahtiah thir karlak i kharnak a si. Valve pum cu a harter a hau, cun valve plate le valve tthutnak cu khar khawhnak ding caah pehzulh tein vawlei ah hren a hau. A fekmi kharmi kutka valve sernak caan cu a sau.
3. Hmannak thil sining
Hrennak tthatnak A nemmi kharnak nih cun a luannak a um lo, a harmi kharnak nih cun a herh ning in a sang asiloah a niam kho;
A nemmi seal pawl cu mei nih a kangh khawh lomi an si a herh, cun lumnak sang ah a luang lai, a harmi seal pawl cu a luang lai lo. Emergency kharnak valve har seals cu pressure sang tangah hman khawh a si, soft seals cu hman khawh a si lo. Atu lio ah, VTON i a fekmi kharmi kutka valve a herh.
A nemmi kharnak cu a rawkmi thilri cheukhat ah hman ding a si lo, cun a harmi kharnak kha hman khawh a si;
4. Riantuannak dirhmun
Hard seals cu a herh ning in a sang asiloah a niam kho; a nemmi seal pawl cu mei nih a kangh khawh lomi an si awk a si, cun a nemmi seal pawl nih pumpak seal sang an hmuh khawh. Zeicatiah a niam tukmi lumnak ahcun, a nemmi seal pawl cu an luang lai, a harmi seal pawl nih cun hi bantuk buainak an ngei lo; a harmi kharnak nih a tlangpi in a sang tukmi hneknak kha an tuar khawh, a nemmi kharnak nih cun an tuar kho lo. Tahchunhnak ah, VTON i ramdang in luhpi mi thir kutka valve pawl nih a harmi kharnak an hman, cun a hneknak cu 32Mpa asiloah 2500LB tiang a phan kho; a nemmi kharnak cu hmun cheukhat ah hman khawh a si lo, a ruang cu thilri a luan caah a si, cu bantuk cu a rawk khomi thilri cheukhat); a donghnak ah, a harmi kharnak valve pawl cu a nemmi kharnak nakin a man a fak deuh tawn. Saknak kongah, an pahnih karlak i aa dannak cu a ngan lo, aa dannak bik cu valve tthutnak a si, a nemmi kharnak cu thir a si lo, cun a harmi kharnak cu thir a si
V. Thilri thimnak
A nemmi le a harmi kharnak thimnakkutka valvesa bik in thil kalning, lumternak le hneknak cungah hram aa bunh. A tlangpi in, thilri nih a fekmi thil hme tete a ngeih ahcun asiloah a rawk asiloah a lumnak cu 200 degree nak a sang deuh ahcun, a harmi kharnak hman a tha bik. Tahchunhnak ah, a lum tukmi thli cu a tlangpi in 180-350°C hrawng a si, cucaah a harmi kharnak kutka valve kha thim a hau.
6. Man le man aa dannak
Caliber, pressure le thilri aa khatmi caah, ramdang in luhpi mi a fekmi kharmikutka valvesramdang in luhpi mi nem tein kharmi kutka valve nakin a man a fak deuh; tahchunhnak ah, VTON's DN100 ramdang in luhpi mi thir thir kutka valve cu DN100 ramdang in luhpi mi thir nem tein kharmi kutka valve nakin 40% in a man a fak deuh; riantuannak dirhmun tangah a fekmi kharmi kutka valve le a nemmi kharmi kutka valve pahnih hman khawh an si ahcun, man ruah tikah, ramdang in a rami nem tein kharmi kutka valve kha thim i zuam.
7. Riantuan caan aa dannak
Soft seal timi cu seal pahnih khatlei cu a tlawm deuhmi thilri in sermi a si tinak a si. A tlangpi in chim ahcun, a nemmi kharnak tthutdan cu thir a si lomi thilri in sermi a si i a fekmi, a harmi le lumnak a tei khomi a si. A kharnak riantuannak a ttha i a luannak a um lo, asinain a nunnak le lumnak he aa tlak khawhnak cu a ttha lo ngai. A harmi kharnak cu thir in sermi an si i kharnak riantuannak a ttha lo ngai, asinain thil sertu cheukhat nih cun a luannak a um lo tiah an ti.
A nemmi kharnak hna i an ṭhatnak cu kharnak rianṭuannak ṭha a si, cun a ṭhatlonak cu a tar a fawi, a rawk i a rawk, cun a caan tawite lawng hman khawh a si. Hard seals cu caan saupi an hman khawh, asinain an sealing riantuan ning cu a nemmi seals he tahchunh ahcun a ttha lo ngai. Hi seal phun hnih hna nih hin pakhat le pakhat an i bawmh khawh. Hrennak kongah, a nemmi kharnak cu a ttha deuh, asinain atu cu a harmi kharnak nih aa tlakmi herhmi zong a tlinh khawh cang.
A nemmi kharnak nih a rawk khomi thilri cheukhat caah a herhmi thil tuahning kha a tlinh kho lo, asinain a harmi kharnak nih hi buainak hi a tawlrel khawh!
Hi seal phun hnih hna nih hin pakhat le pakhat an i bawmh khawh. Hrennak kongah, a nemmi kharnak cu a ttha deuh, asinain atu cu a harmi kharnak nih aa tlakmi herhmi zong a tlinh khawh cang!
A nemmi kharnak hna i an ṭhatnak cu kharnak rianṭuannak ṭha a si, cun a ṭhatlonak cu a tar a fawi, a rawk i a rawk, cun a caan tawite lawng hman khawh a si.
A harmi kharnak hna cu caan sau an nung, asinain a nemmi kharnak nakin kharnak cu a chia deuh.
