Xaiv Workflow
Txheeb xyuas cov xov xwm & cov xwm txheej (T / P / Corrosivity)
Xaiv lub cev / foob cov ntaub ntawv
Txheeb xyuas qhov loj me & kev sib txuas hom
Xaiv Kev Ua Haujlwm (Phau Ntawv / Pib)
Txheeb xyuas cov kev xav tau tshwj xeeb (hluav taws kub - kev nyab xeeb / ovi - zoo li qub)
Tus nqi -} Cov Nyiaj Pab
I. Cov Cwj Pwm Xov Xwm
1. Media hom
| Koom haum tshaj xov | Phab Valve |
|---|---|
| Kua / Gases / Chav | Txheem Li Qub |
| Corrosives (acids / alkali) | SS316 / PTFE -} lined lined |
| Viscous / Particulate | Puv - bore los yog v - chaw nres nkoj li qub |
| Khoom Noj / Tshuaj | Huv li qub (ra tsawg dua los yog sib npaug rau 0.8μm) |
2. Qhov ntsuas kub
Cryogenic (<-40°C): Tob - Cryo kho Ss lub cev
High-Temp (>200 degree): Hlau - zaum (wc txheej)
3. Kev Ntsuas Siab
Tsawg - p (pn tsawg dua los yog sib npaug rau 16): Ntab pob tsim
High - p (PN ntau dua los yog sib npaug rau 25): Tsau pob nrog txhawb lub cev
Ii. Txheej Txheem Kev Tsim Kho
A. Lub cev cov ntaub ntawv
| Khoom | Daim ntawv thov |
|---|---|
| Nrum Hlau | Dej / huab cua (tsis - corrosive) |
| SS304 / 316 | Tshuaj lom neeg / Zaub mov |
| PVC / PTFE - txoj hlua | HF Acid Service |
B. FOR cov ntaub ntawv
Ptfe: Tsawg dua lossis sib npaug ntawm 150 degree, zoo tshuaj lom neeg tiv thaiv
Ppl: Tsawg dua lossis sib npaug nrog 300 degree, chav pabcuam
Hlau - rau - hlau: 600 Degree +, Medas Artasity
III. Hom Chaav
| Ntaus | Daim ntawv thov |
|---|---|
| Flanged | Dn ntau dua los yog sib npaug rau 50, siab -} siab |
| Thoo | Dn tsawg dua los yog sib npaug nrog 50, qis -} siab |
| Welded | {- pov thawj (piv txwv li, lpg) |
| Tri -} clamp | CIP / PIP txheej txheem |
IV. Txoj Kev Ua Raws Cai
Kev Lag Luam Kev Ua Haujlwm
Rab nyom: DN tsawg dua los yog sib npaug rau 100, tsawg torque
Tus thawv: DN ntau dua los yog sib npaug rau 150, Siab Torque
Kev ua tshuab ua haujlwm
| Ntaus | Yam uas pab |
|---|---|
| Pneumatic | Tawg - pov thawj (ATEX) |
| Noj fai fab | Cov chaw taws teeb tswj |
| HYDRAULIC | High - torque (cov ntawv thov Dam) |
V. Cov kev xav tau tshwj xeeb
{- kev nyab xeeb: API 607 / 6FA ua raws cai (Foob Hlau)
Anti - zoo li qub: Grounding hlau rau flammable media
Bi {- directional: Lng kev siv
VI. Tus nqi txiav txim siab
| Yam tseem ceeb | Kev qhia |
|---|---|
| Tus nqi pib | Nrum Hlau + PTFE (feem ntau muaj nyiaj txiag) |
| Tus nqi lifecycle | Hlau rooj zaum rau cov mob hnyav |
