1. {{-254 degree - -101 degree, rau "ultra-tsis kub"
Muaj feem xyuam rau "ultra-tsis muaj kub nyhiab" ({1}} degree 〔〔〔〔{〔〔degree degree〕). Cov khoom siv tseem ceeb yuav tsum tau ua kom muaj kev txwv tsis pub siv lub tshuab hlau, tooj liab los yog txhuas alloy nrog lub ntsej muag ntsej muag. Nws cov khoom siv kub tsawg dua tom qab kev kho cua sov tom qab kev kho cua sov, tshwj xeeb tshaj yog cov kev cuam tshuam ntawm kub, yuav tsum ua kom tiav cov qauv. Cov hlau hauv qab no cov hlau hauv qab no tuaj yeem siv rau cov roj ultra-tsawg. ASTM A351 CF8M, CF3M, CF8, CF3; ASTM A182 F316, F316L, F304, F304L; ASTM 433 316, 316L, 304, 304L; Lub valve lub cev, valve npog, rooj vag lossis valve disc ntawm ultra-valas valve yuav tsum tau cryogenically kho hauv kua nitrogen ({}} degree) ua ntej xaus.
2. {{{-100 degree - -30 degree, rau "tsawg kub nyob"
Cov ntaub ntawv tseem ceeb haum rau cov khoom kub tsawg ({}}}} {{} degree thiab martensitic steel rau qhov kub siab qhov chaw. Tsawg kub kub Austenitic stainless hlau muaj xws li ASTM A351 CF3M, F304L, ASTM A {12}}, 316L, 304, 304 xyoo. Qhov saum toj no Austenitic stainless hlau kuj tsim rau kev ua haujlwm kub ntawm {16}} degree ~ {17}} degree. Cov hlau ferrite thiab martensitic steels rau qhov ntsuas kub tsawg suav nrog ATM A352 LCA ({{19} degree); LCB, LCC ({{{{}} degree); LC1 ({-59 degree); LC2, LC2.1 (-73 degree); LC3 ({-100 degree). Txawm hais tias thawj tus nqi ntawm cov ntaub ntawv hauv ASTM A352 tus qauv yog tsawg, tshuaj lom neeg thaum lub sij hawm smelting yuav tsum muaj kev ntseeg siab thiab nruj lub Hoobkas sab hauv cov qauv. Cov txheej txheem kev kho cua sov yog qhov nyuaj thiab tseev kom muaj ntau yam npau taws. Thaum qhov kev cuam tshuam kub tsawg tsis tau raws li cov qauv yuav tsum tau ua tiav, nws tsis raug siv los ua cov hlau tsawg.
3. {{-29 degree -200 degree, "ntsuas kub me,
Peb hu rau qhov qub uas ua haujlwm hauv qhov ntsuas kub ntawm -29 degree -200 degree ". Cov laj thawj tseem ceeb yog: Qhov ntsuas kub no yog qhov tsim nyog rau cov ntaub ntawv tseem ceeb siv los ua cov khoom siv qub; Thiab nws yog qhov kev txwv sab sauv ntawm kev txhim kho corrosion-resistant ua hauj lwm ntawm corrosion-resistant stainless hlau hauv acidic media, piv txwv: CF3; 304, 304L hauv nitric acid tawm ua hauj lwm kub tsawg dua los yog sib luag rau 200 degree; CF8M, CF3M; 316, 316L hauv acetic anid tawm ua hauj lwm kub tsawg dua los yog sib luag rau 200 degree; 200 degree yog qhov ntau tshaj plaws ntawm sealing ntsiab (xws li Sealing Valve lub rooj, ntim, ntim, thiab lwm yam) Siv polytetrosraethylene li qub; 200 degree yog qhov siab tshaj plaws ua haujlwm ntawm cov roj hmab silicone (SI) thiab fluororubber (FKM); Thiab rau kev ua haujlwm li qub ua haujlwm hauv "Hydrogen" cov kev mob, tus nqi ntawm hydrogen molecules dissociated rau hydrogen hauv qab no 200 degree tuaj yeem tsis quav ntsej, thiab lwm yam.
4. >200 degree {-325 degree, "nruab nrab kub valve"
We call the valves working in the temperature range of >200 degree {-325 degree "Nruab Nrab Nruab Nrab". Qhov laj thawj tseem ceeb yog qhov no qhov ntsuas kub no tsis haum rau PTFE, uas yog, PTFE tsis tuaj yeem siv rau pta-polyphenylene (ppl). Para-polyphenylene tuaj yeem siv los ua lub caij sib khi rau kev ua haujlwm kub tsawg dua lossis sib npaug txog 325 degree; Qhov ntsuas kub no yog qhov txwv qhov loj tshaj plaws ntawm qhov siab tshaj plaws ua haujlwm ntawm cov li qub ntawm cov hlau thiab lwm yam khoom siv.
5. >325 Degree {{-425 degree, "sub-high-siab valve"
We call the valves working in the temperature range of >325 Degree {-425 degree "sub-siab-kub valve". Qhov laj thawj tseem ceeb yog tias cov ntaub ntawv sib khi ntawm cov khoom siv hluav taws xob tsis zoo Qhov ntsuas kub no yog qhov txwv qhov loj tshaj plaws ntawm kev ua haujlwm kub tshaj plaws ntawm cov hlau. Ib qho ntxiv, peb hu rau qub ua haujlwm hauv qhov ntsuas kub no "vim tias muaj cov khoom siv kub, siv rau cov pa hluav taws xob ntau dua li cov hlau kub thiab lwm yam. Yog li ntawd, qhov ntsuas kub no tuaj yeem hais kom tsis muaj qhov kub nyob hauv qhov kev nkag siab tseeb. Yog li ntawd, nws yog qhov tsim nyog dua hu rau cov li qub nyob rau hauv qhov kev ua haujlwm no ua haujlwm "sub-high ntsuas kub".
6.> 425 Degree -550 degree, "Kub Qib I Valve", xa mus rau qib PT
Kev ua haujlwm kub ntawm lub valve yog 425 ~ 550 degree, uas tau txhais raws li qhov siab kub thiab raug xa mus raws li PI qib). Cov khoom siv tseem ceeb ntawm PI qib valve yog "qhov kub ntawm cov roj carbon chromium npib zoo li kub-resistant hlau-resprome kub-resistant steel-resistant hlau" raws li CF8 hauv ASTM A351 tus qauv. Vim tias PI qib yog lub npe tshwj xeeb, lub tswvyim ntawm kev siv cov hlau kub siab stainless (p) muaj nyob ntawm no. Yog li ntawd, yog tias ua haujlwm nruab nrab yog dej los yog chav dej, txawm hais tias kub siab dua lossis muaj kev sib npaug los yog sib npaug los yog sib npaug) kuj tseem siv tau; Txawm hais tias high-kub steel C5 (ZG1Cro) kuj tseem siv tau rau cov sulphur-muaj cov roj ntsha, lawv tsis tuaj yeem hu ua PI qib ntawm no.
7.> 550 degree {-650 degree, "Kub-Qib IX Valve", xa mus rau qib PT
Kev ua haujlwm kub ntawm lub valve yog 550 ~ 850 degree, uas tau cais raws li cov qib siab II (xa mus rau qib PII). PII qib siab siab tsheb siab yog feem ntau siv hauv cov roj catalytic cracking units nyob rau hauv cov chaw khaws khoom noj. Nws suav nrog high-lined hnav-resistant rooj vag siv siv hauv peb-sib hloov nozzles thiab lwm qhov chaw. Cov khoom tseem ceeb ntawm cov qib qeb npoo yog "qhov kub-kub roj carbon chromium siv sijhawm kub-siab dua cov hlau" raws li CF8 hauv ATTM A351 tus qauv.
8.> 650 DEGREE -730 degree, "Kub Degree," Kub Qib III Valve ", xa mus rau qib PT
Kev ua haujlwm kub ntawm lub valve yog 650 ~ 730 degree, uas tau cais raws li qhov siab qib siab III (raug xa mus rau qib PIII). Piii qib siab li qub yog siv tau nyob rau hauv loj hnyav roj catalytic cracking units nyob rau hauv cov chaw khaws khoom noj nyob rau hauv. Cov khoom siv tseem ceeb ntawm Piii qib kev kub siab yog "qhov kub siab rau qib III Moddle Molybdenum muaj zog kub-resistant steel-respromen
9.> 730 Degree -816 degree, "Kub Qib IV Valve", hu ua PT Qib
Kev ua haujlwm kub ntawm lub valve yog 73 {14}}} ~ 816 degree, uas tau cais raws li qhov siab kub thiab tau hais raws li PIV qib). Qhov kev txwv sab sauv ntawm kev ua haujlwm kub ntawm piv li qub yog 816 degree tau muab los ntawm International Aflectitive tau xaiv rau Valve Tsim yog 816 degree. Tsis tas li ntawd, tom qab kev ua haujlwm kub tshaj 816 degree, cov hlau yog ze rau nkag mus rau hauv thaj chaw tsis pom zoo. Nyob rau lub sijhawm no, cov hlau yog nyob rau hauv cov yas deformation ntau. Cov hlau muaj cov ntsej muag zoo thiab yog qhov nyuaj rau kev ua haujlwm siab ua haujlwm siab thiab cuam tshuam yam tsis muaj deformation. Cov khoom siv tseem ceeb ntawm piv li qub yog cf8m raws li lub hauv paus "kub thiab txias gravbon Ck -20 Thiab tTM A182 tus Qauv F310 (Nco ntsoov: C tseem ceeb rau 0.050%) thiab thiab lwm yam kub-reistant stainless hlau.
10.> 816 Qib yog "Kub Kub V-Qib Valve", hu ua PT Qib
Kev ua haujlwm kub ntawm lub valve yog siab dua> 816 degree, uas yog hu ua kev kub kub v-qib (raug xa mus rau qib PV). PV-qib kev kub siab-ntsuas kub (li qub siv raws li kev txiav tawm, xws li: phlu nrog thermal rwb thaiv tsev lossis dej txias, los xyuas kom meej qhov kev ua haujlwm ib txwm muaj ntawm lub valve. Yog li ntawd, tsis muaj kev cai ntawm cov kev txwv sab sauv ntawm kev ua haujlwm kub ua haujlwm ntawm PV-qib siab-ntsuas kub. Qhov no yog vim hais tias kev ua haujlwm kub ua haujlwm ntawm lub valve tsis tswj cov ntaub ntawv ib leeg, tab sis los ntawm cov qauv tshwj xeeb, thiab cov qauv kev tsim tshwj xeeb yog tib yam. PV-qib kev kub siab tau xaiv tau cov khoom tsim nyog uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub valve raws li lawv txoj kev ua haujlwm nruab nrab, ua haujlwm siab. Hauv PV-qib kev kub siab-ntsuas kub, cov pob txiab lossis npauj npaim Lawv tuaj yeem tiv thaiv corrosion hauv oxidation thiab txo cov roj av hauv qab 1150 degree, tab sis tsis tuaj yeem tiv taus kev cuam tshuam thiab kev thauj khoom siab.
Kev ua haujlwm kub ntawm lub valve tau muab faib ua cov theem saum toj kawg nkaus saum toj no. Nrog xws li kev faib tawm meej meej, ib qho kev tshawb fawb paub ntau yog muab rau cov qauv tsim, thiab kev xaiv ntawm lub valve.
