High-end rooj vag valve rau cov pa kob
| Hom | Rooj vag Valve |
| Qauv | Z962Y-900 |
| Nominal Dia | DN 150-500 |
Cov khoom siv yog siv rau kev siv dej ntawm nuclear fais fab AP1000 unit. Thaum nws siv, lub rooj vag valve yuav tsum nyob rau hauv tag nrho qhib los yog tag nrho kaw txoj hauj lwm es tsis txhob ua hauj lwm raws li kev khiav dej num thiab siab tswj.
- Lub valve txais tus kheej-sealing qauv thiab nws ob qhov kawg yog welded kev twb kev txuas.
- Cov txheej txheem kaw muaj cov npoo hom dual-flashboard nrog qhov chaw kho tau, universal sab saum toj thiab tuav-down board. Coj los ntawm kev taw qhia baffle hauv lub cev valve, nws ua rau nce thiab nqis.
- Nrog cobalt-raws li txhav alloy build-up welding, lub sealing nto nta kub tsis kam, puas kuj, corrosion kuj, anti-scratching thiab ntev kev pab cuam lub neej; tsim-up vuam qhov siab ntawm valve disc thiab lub rooj ≥3mm.
- Nrog kev taw qhia baffle, lub valve lub cev muab tag nrho cov kev taw qhia mob stroke rau flashboard qhib thiab kaw.
- Nyob rau hauv kev tiv thaiv corrosion thiab nitrogenization kev kho mob, lub valve qia nto nta zoo corrosion kuj, abrasion tsis kam thiab txhim khu kev qha khoom lub thawv sealing.
- Tsis siv neeg wedge hom dual-flashboard qauv nrog adjustable center muaj cov yam ntxwv nram qab no: hardened sab saum toj center thiab cushion block (spherical contact) tuaj yeem kho lub kaum sab xis ntawm flashboard thiab valve lub rooj zaum kom lawv cov sealing nto cling nruj thiab xyuas kom nruj sealing; ib pawg ntawm kev kho gaskets yog ntsia nruab nrab ntawm nruab nrab nruab nrab thiab flashboard los kho qhov dav ntawm flashboard thiab them nyiaj puas tom qab flashboard ua haujlwm thiab kho. Elastic zawj yog teem nruab nrab ntawm sab laug thiab sab xis flashboards kom tsis txhob daig thaum lub valve kaw. Cov txheej txheem flashboard muaj kev sib hloov tau zoo thiab kev tsim khoom loj heev, thiab nws cov nqi dav dav yog siab dua li qhov sib npaug dual-flashboard thiab wedge elastic flashboard qauv.
- Lub valve txais cov qauv ntawm cov khoom siv vuam-ntawm lub rooj zaum. Magnetic hmoov nrhiav tau yog ua rau fillet weld kom ntseeg tau tias vuam sib koom ua tau zoo ua raws li cov qauv kev cai.
- T-hom grooved kev twb kev txuas yog saws rau valve qia thiab flashboard ntawm tsis siv neeg wedge dual-flashboard rooj vag valve nrog adjustable center. Lub rooj tuav tuav yog teem rau ntawm T-hom zawj ntawm lub flashboard kom txwv tsis pub qhib ntawm sab laug thiab sab xis flashboards tom qab lub valve qhib thiab tiv thaiv flashboard poob. Lub taub hau ntawm lub valve qia yog sphere. Thaum lub sij hawm kaw lub valve, lub zog muaj zog yog exerted los ntawm lub valve qia ntawm lub rooj tsavxwm tuav kom kaw lub zog ntau dua txawm tias lub flashboard kaw thiab lav txawm tias kev ntxhov siab ntawm flashboard thiab valve lub rooj sealing nto thiab zoo dua sealing.
- Nrog pendant collet ua qhov tseem ceeb ntawm kev ntxhov siab, qhov kev sib khi ntawm tus kheej tau txais qhov forged thiab nws cov ntaub so ntswg compactness yog superior rau vaj huam sib luag. Meanwhile, nws txais kev sib koom ua ke ultrasonic nrhiav thiab nto magnetic hmoov txheej txheem kom paub tseeb tias forged ib feem zoo ua raws li tus qauv yuav tsum tau.
