✧ Nqe lus piav qhia
Cryogenic ntiaj teb li qub nrog lub kaus mom txuas ntxiv tsim los rau kev ua haujlwm ntawm qhov kub thiab txias li -196 ° C yog tsim tshwj xeeb los tswj cov xwm txheej huab cua ntawm kev siv cryogenic. Lub kaus mom txuas ntxiv muab cov rwb thaiv tsev ntxiv thiab kev tiv thaiv rau lub qia valve thiab ntim kom ntseeg tau tias kev ua haujlwm zoo ntawm qhov kub qis. Cov li qub no feem ntau yog siv rau hauv kev lag luam xws li LNG (liquefied natural gas) ua, kev tsim cov pa roj, thiab lwm yam kev siv cov kua dej cryogenic. Cov ntsiab lus tseem ceeb rau cryogenic ntiaj teb li qub rau -196 ° C suav nrog: Cov khoom siv: Cov li qub no tau tsim los siv cov khoom siv tshwj xeeb. uas tuaj yeem tswj hwm lawv txoj kev ncaj ncees thiab kev ua haujlwm nyob rau hauv qhov chaw cryogenic. Cov khoom siv feem ntau suav nrog cov hlau tsis muaj steel, carbon hlau, thiab lwm yam alloys uas muaj qhov kub thiab txias.Sealing thiab Packing: Lub valve sealing Cheebtsam thiab ntim khoom yuav tsum tau tsim kom muaj txiaj ntsig zoo thiab hloov tau ntawm qhov kub tsis tshua muaj siab los tiv thaiv kev xau thiab tswj kom nruj kaw. Kev Ntsuas thiab Kev Ua Raws Cai: Cryogenic ntiaj teb li qub rau qhov kub tsis tshua muaj kev soj ntsuam nruj kom ntseeg tau tias kev ua tau zoo thiab ua raws li cov qauv kev lag luam rau cov kev pabcuam cryogenic.Insulation: The Extension bonnet tsim muab rwb thaiv tsev los tiv thaiv cov khoom tseem ceeb los ntawm huab cua txias thiab kom tsis txhob muaj kev pheej hmoo ntawm cov dej khov tsim uas tuaj yeem cuam tshuam lub valve ua haujlwm.Cov li qub no yog cov khoom tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov kua dej cryogenic ntws.
✧ Nta ntawm Cryogenic Globe Valve Extended Bonnet rau -196 ℃
1. Lub valve bonnet yog tsim los txuas ntxiv bonnet qauv, uas tuaj yeem cais cov kev cuam tshuam ntawm cov xov xwm tsis tshua muaj kub ntawm cov khoom ntim, tiv thaiv kev ua haujlwm ntawm lub hau npog, thiab tseem ua rau lub valve qhib thiab kaw tau yooj yim;
2. lub muab tub lim txais yuav saj zawg zog graphite los yog polytetrafluoroethylene ua ke qauv, nrog zoo kub tsis kam;
3. qhov kub-kub valve txais cov qauv ntawm kev qhib lub qhov decompression ntawm lub valve tub ntxhais. Gasket txais stainless hlau tawv clip polytetrafluoroethylene los yog saj zawg zog graphite winding qauv;
4. Thaum lub valve raug kaw, txhawm rau tiv thaiv qhov kub nruab nrab hauv lub valve chamber los ntawm qhov kub thiab txias, ua rau lub siab tsis zoo, cov qauv kev pab cuam siab yog muab rau ntawm qhov siab siab ntawm lub rooj vag lossis lub valve lub cev;
5. lub sealing nto ntawm lub valve surfacing cobalt-raws li cemented carbide, tungsten carbide ntawm qhov kub thiab txias deformation yog me me, hnav tsis kam, tuaj yeem tswj kev sib khi zoo.
Vim tias cov khoom tso tawm ntawm cov kua hluav taws xob qis xws li ethylene, kua oxygen, kua hydrogen, liquefied natural gas, liquefied petroleum thiab lwm yam khoom tsis yog tsuas yog flammable thiab tawg, tab sis kuj gasification thaum cua sov, thiab lub ntim nthuav ntau pua zaus thaum gasification. Cov khoom siv ntawm qhov ntsuas kub qis yog qhov tseem ceeb heev, thiab cov khoom siv tsis tsim nyog, uas yuav ua rau sab nraud los yog sab hauv to ntawm lub plhaub thiab sealing nto; Cov khoom siv dav dav, lub zog thiab cov hlau tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev siv lossis txawm tawg; Ua rau liquefied natural gas nruab nrab los ntawm qhov tawg. Yog li ntawd, nyob rau hauv tus txheej txheem ntawm kev tsim, tsim thiab tsim cov valve uas tsis tshua muaj kub, cov khoom siv kho mob yog qhov tseem ceeb ntawm qhov teeb meem.
✧ Qhov zoo ntawm Cryogenic Globe Valve Extended Bonnet rau -196 ℃
Thaum lub sij hawm qhib thiab kaw txheej txheem ntawm forged steel ntiaj teb valve, vim hais tias kev sib txhuam ntawm lub disc thiab sealing nto ntawm lub valve lub cev yog me dua li ntawm lub rooj vag valve, nws yog hnav-resistant.
Qhov qhib lossis kaw stroke ntawm lub valve qia yog luv luv, thiab nws muaj kev txhim khu kev qha kev txiav tawm, thiab vim hais tias qhov kev hloov ntawm lub rooj zaum qhov chaw nres nkoj valve yog proportional rau stroke ntawm lub valve disc, nws yog heev haum rau kev hloov. ntawm tus nqi ntws. Yog li ntawd, hom valve no yog qhov tsim nyog rau kev txiav tawm lossis kev tswj hwm thiab throttling.
