Rhuav lub valve yog lub valve uas siv ib lub taub hau hlau kom ua tiav cov hlua khi. Nws cov hom phiaj tseem ceeb yog los daws cov xoom uas yuav tsum muaj ntawm cov xov xwm muaj kev pheej hmoo. Cov hauv qab no yog cov khoom siv tshwj xeeb thiab nta:
1. Cov Tub Rog Loj-Sealing Kev Tswj Xyuas
Txhaum mob, tawg thiab toxic
Muaj feem rau cov kav dej txaus ntshai xws li cov pa roj, ammonia, roj av, thiab lwm yam, txhawm rau tiv thaiv kom tsis txhob muaj kev tiv thaiv kev nyab xeeb.
Heev corrosive media
Muaj peev xwm siv cov kua ntawm cov kua xws li cov kua qaub, alkalis, thiab cov khoom siv hluav taws xob, xws li cov kua qaub thiab cov khoom siv alkali.
Heev toxic thiab tsis tshua muaj xov xwm
Siv nyob rau hauv cov tshuaj thiab kev lag luam nuclear los tswj cov cyanide, cov khoom siv hluav taws xob thiab lwm cov scenes uas yuav tsum tau ntim kev sib khi.
2. Cov ntsiab lus tseem ceeb ntawm cov txheej txheem kev lag luam
| Yam muaj hauj lwm | Cov Ntawv Thov | Qhov Zoo |
|---|---|---|
| Petrochemical | Kev kub siab thiab kev kub siab xa dej siab ntawm cov roj ua kom zoo nkauj thiab cov khoom siv Ethylene tawg. | Kev kub siab kuj (tsawg dua los yog sib npaug rau 425 degree), nruab nrab erosion tsis kam |
| Fai fab | Lub zog tsob nroj chav dej, dej ncig tswj kev tswj hwm (xws li lub zog me me sib cais valve) | Haum rau qhov kub thiab txias thiab cov pa siab siab, zam kev laus thiab xau ntawm cov khoom lag luam tsoos |
| Kws muag khoom \/ khoom noj | Aseptic ntau lawm kab, siab purity me me xa (xws li cov tshuaj tiv thaiv kev tsim khoom). | Tshem tawm cov microbial paug thiab sib ntsib tu cov qauv kev nyiam huv |
3. Kev Ua Haujlwm Ua Haujlwm Tshwj Xeeb Kev Haum
Nqus plua plav thiab ultra-tsawg kub ib puag ncig
Siv rau semiconductor manufacturing nqus dej pipelines, kua nitrogen thiab tsheb thauj mus los tiv thaiv cov pa roj sab nraud.
Nquag qhib thiab kaw cov scenarios
Lub botrows tuaj yeem tiv thaiv kaum ob txhiab lub telescopic kev taw thiab yog qhov tsim nyog rau cov txheej txheem muaj cov khoom lag luam uas xav tau kev hloov kho siab.
Kev tswj cov kev saib xyuas ntev ntev-pub dawb
Lub neej ntawm cov hlau taub hau yog ntau dua 10 xyoo, txo cov zaus ntawm shutdown thiab txij nkawm (piv nrog cov khoom lag luam ib txwm).
4. Cov hom valve thiab txwv tsis pub
Muaj Ntau Hom Valve
Feem ntau tsim cov li qub (nyiaj txiag rau ntau dua 80% ntawm kev ua lag luam), ib qho me me ntawm cov pob zeb ua tiav kev sib khi ntawm cov zeem zig.
Txwv tsis pub
Lub siab tiv thaiv qib ntawm lub qia feem ntau yog tsawg dua los yog sib npaug ntawm chav kawm 600, thiab kev sib tw loj thiab ntev dhau los yuav tsum zam.
