High - hish pob li qub tau qhia thawj zaug hauv xyoo 1950. Nrog kev nce qib sai ntawm kev tshawb fawb thiab thev naus laus zis, thiab kev txhim kho txuas ntxiv hauv cov txheej txheem ntau lawm thiab cov qauv khoom lag luam, lawv tau tsim nrawm rau hauv ib hom valve loj hauv 40 xyoo.
Siab -} high ball pall feem ntau yog siv los kaw lossis txuas xov tooj rau hauv lub xov tooj pipelines, thiab tseem siv tau rau cov kev cai kua thiab tswj. Lub zog shear zog ntawm v {2} Daim Pob Pob Tawb thiab Mack} Cawv} clad pob valve ua rau muaj cov lus qhia thiab cov khoom ua kom zoo. Multi {{{txoj kev ball li qub tsis muaj kev tswj hwm lub zog, tab sis tuaj yeem kaw ib qho channel thaum txuas lwm ob. Hom valve no feem ntau muab cov kab rov tav ntawm cov kav dej.
Ua haujlwm ua haujlwm ntawm high - h siab npas
Siab -}} siab pob li qub feature ib 90 -℃sib txuas cov lus tsa suab. Lub plug lub cev yog lub pob kheej kheej nrog lub voj voog los ntawm - lub qhov lossis channel khiav los ntawm nws axis. Pob li qub yog feem ntau siv nyob rau hauv lub pipelines kom kaw, faib, thiab hloov cov kev taw qhia kev tshaj tawm. Lawv yuav tsum tau tsuas yog 90 -℃kev sib hloov thiab minimal torque kom ua tiav cov foob kaw. Pob li qub yog cov feem ntau haum rau siv raws li ntawm / tawm thiab cov kev tsim tawm tsis ntev los no tau tsim rau kev siv lub pob thiab tswj, xws li v-puab pob.
Siab -} h siab npas tau cov qauv los ntawm lawv cov qauv kev cog lus, kev tsim kho kom yooj yim, kev kho yooj yim, thiab txij nkawm yooj yim, thiab kev txij nkawm yooj yim, thiab kev txij nkawm yooj yim, thiab kev txij nkawm yooj yim, thiab kev txij nkawm yooj yim, thiab kev txij nkawm yooj yim. Kev sib khi saum npoo av thiab cov pob saum npoo ib txwm nyob hauv txoj haujlwm kaw, ua rau lawv tsis txhob raug yaig los ntawm nruab nrab. Lawv yooj yim ua haujlwm thiab tswj hwm. Lawv tsim nyog rau kev ua haujlwm dav dav xws li dej, cov kuab tshuaj, thiab cov pa roj carrogen, hydrogen peroxide, methane, thiab ethaneene, thiab ethylene. Lawv tau siv dav hauv ntau yam kev lag luam. Pob valve lub cev tuaj yeem yog ib qho - daim lossis modular.
Qhov zoo ntawm kev siab -} siab pob li qub
1. Cov kua dej tsawg tiv: tag nrho - bore pob li qub muaj zoo tsis muaj leej twg txaus tsis kam.
2. Cov qauv yooj yim, kev sib xyaw loj, thiab lub teeb yuag.
3. Thawb thiab txhim khu kev qha. Lawv muaj ob qhov chaw sealing, thiab cov chaw sealing yog ua los ntawm ntau cov plastics, muab kev sib khi zoo heev thiab ua tiav cov foob. Lawv tseem muaj dav siv hauv lub tshuab nqus tsev.
4. Lawv yooj yim rau kev khiav lag luam thiab qhib thiab kaw sai sai. Ib qho yooj yim 90℃kev sib hloov los ntawm qhib tag nrho cov chaw taws teeb tswj {} Kev sib tw yooj yim, ua rau nws yooj yim kom disassemble thiab hloov.
6. Thaum qhib tag nrho, kaw qhov chaw sib khi ntawm pob thiab valve nyob ntawm nruab nrab, tiv thaiv kev yaig ntawm lub valface surfaces thaum lub nruab nrab hla.
7. Cov ntawv thov ntau: Cov kev sib txawv ntawm ob peb millimeters rau ob peb metres, thiab tuaj yeem siv rau hauv cov ntawv thov los ntawm lub tshuab hluav taws xob siab.
8. Vim tias lub pob valve muaj cov nyiaj so so thaum qhib thiab kaw, nws tuaj yeem siv rau hauv cov xov xwm uas muaj cov khoom me me.
