Kev khiav hauj lwm kub ntawm lub valve yog txiav txim los ntawm cov khoom ntawm lub valve.Qhov kub ntawm cov khoom siv feem ntau rau li qub yog raws li hauv qab no:
Valve ua haujlwm kub
Grey cam khwb cia hlau valve: -15 ~ 250 ℃
Malleable cam khwb cia hlau valve: -15 ~ 250 ℃
Lub cev hlau valve: -30 ~ 350 ℃
High nickel cam khwb cia hlau valve: lub siab tshaj plaws kev khiav hauj lwm kub yog 400 ℃
Carbon steel valve: -29 ~ 450 ℃, pom zoo kub t <425 ℃ hauv JB / T3595-93 tus qauv
1Cr5Mo, alloy steel valve: qhov siab tshaj plaws ua haujlwm kub yog 550 ℃
12Cr1MoVA, alloy steel valve: qhov siab tshaj plaws ua haujlwm kub yog 570 ℃
1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti stainless hlau valve: -196 ~ 600 ℃
Copper alloy valve: -273 ~ 250 ℃
Yas valve (nylon): qhov siab tshaj plaws ua haujlwm kub yog 100 ℃
Yas valve (chlorinated polyether): siab tshaj plaws ua haujlwm kub 100 ℃
Yas valve (polyvinyl chloride): siab tshaj plaws kev khiav hauj lwm kub 60 ℃
Yas valve (polytrifluorochloroethylene): -60 ~ 120 ℃
Yas valve (PTFE): -180 ~ 150 ℃
Yas valve (natural roj hmab diaphragm valve): Qhov siab tshaj plaws kev khiav hauj lwm kub 60 ℃
Yas valve (nitrile roj hmab, neoprene diaphragm valve): qhov siab tshaj plaws ua haujlwm kub yog 80 ℃
Yas valve (fluorine roj hmab diaphragm valve): qhov siab tshaj plaws kev khiav hauj lwm kub yog 200 ℃
Thaum cov roj hmab los yog yas siv rau hauv ob sab phlu, qhov kub ntawm cov roj hmab thiab cov yas yuav tsum yeej
Ceramic li qub, vim lawv qhov tsis zoo kub tsis kam, feem ntau yog siv rau hauv kev ua haujlwm qis dua 150 ° C.Tsis ntev los no, ib qho kev ua tau zoo tshaj plaws ceramic valve tau tshwm sim, uas tuaj yeem tiv taus qhov kub thiab txias hauv qab 1000 ° C.
Cov iav li qub muaj qhov kub tsis zoo thiab feem ntau yog siv hauv kev ua haujlwm hauv qab 90 ° C.
Qhov kub tsis kam ntawm lub enamel valve yog txwv los ntawm cov khoom ntawm lub nplhaib sealing, thiab qhov siab tshaj plaws ua haujlwm kub tsis tshaj 150 ° C.
Lub cev cov ntaub ntawv tseem ceeb suav nrog: C carbon steel, I 1Cr5Mo chromium molybdenum steel, H Cr13 series stainless hlau, K malleable cam khwb cia hlau, L aluminium alloy, P 0Cr18Ni9 series stainless hlau, PL 00Cr19Ni10 series stainless hlau, Q ductile hlau, R 0Cr12Ni12Mo2 series Stainless hlau, RL 00Cr17Ni14Mo2 series Stainless hlau, S yas, T tooj liab thiab tooj liab alloy, Ti titanium thiab titanium alloy, V chromium molybdenum vanadium hlau, Z grey cam khwb cia hlau.
