Txoj Valve Khoom Xaiv

Hauv kev teb cov lag luam, lub valve yog qhov tseem ceeb ntawm cov dej ntws, uas yog siv dav hauv ntau cov roj av xws li roj av, metallurgy thiab yog li ntawd. Nws cov kev ua tau ncaj qha cuam tshuam nrog kev nyab xeeb rau kev nyab xeeb, kev ruaj khov thiab ua haujlwm tau zoo ntawm tag nrho cov kab ke. Yog tias cov khoom siv tsis raug xaiv kom raug, lub VALVE, hnav, deformage thiab lwm yam teeb meem, tab sis kuj yuav ua rau muaj kev nyab xeeb kev nyab xeeb. Yog li ntawd, kev nkag siab tob ntawm qhov kub tsis kam thiab tshaj tawm cov yam ntxwv ntawm cov kws qhia kev lag luam kom ntseeg tau tias kev nce qib kev txhim kho ntawm kev tsim khoom.
Cov ntaub ntawv hlau yog ib qho ntawm cov khoom siv feem ntau ntawm cov khoom lag luam valve, thiab muaj ntau yam sib txawv hlau cov ntaub ntawv nrog cov cua kub sib txawv.
Grey cam khwb cia hlau li cas muaj tus nqi qis thiab yooj yim}
Vim nws cov khoom siv zoo dua thiab corrosion tsis kam, qhov ntsuas kub ntawm zas degree c. Qhov no ua rau ciaj hlau li qub siv hauv ntau daim teb.
Qhov ntsuas kub ntawm cov roj carbon steel yog -29 degree rau 450 degree, thiab cov pom zoo T<425℃ is in the JB/ T3595-93 standard. In this temperature range, carbon steel can maintain good strength and toughness, and meet the requirements of most conventional working conditions.
Alloy steel hlau li qub qhia ntau qhov kub siab ua kom zoo tshaj plaws yog 57 degree c, thiab qhov siab tshaj plaws, uas yog qhov siab tshaj plaws hauv chav dej kub, thiab cov roj av, tshuaj lom neeg thiab lwm yam khoom siv.
Stainless hlau li qub yog paub rau lawv zoo heev corrosion tsis kam thiab siab thiab tsawg kub tsis kam. Ntawm lawv, 1cr18ni9ti thiab 1cr18ni12mo12mo2ti stainless hlau muaj ntau yam kev ua tau zoo heev thiab muaj kev kub ntxhov, tshuaj noj, tshuaj lom neeg thiab lwm thaj chaw.
Cov ntaub ntawv sib txawv hlau muaj ntau yam kev tshaj tawm vim lawv qhov sib txawv ntawm cov tshuaj lom neeg thiab cov khoom siv lub cev.
Grey cam khwb cia hlau Valve
Nws yog qhov haum rau dej, chav, huab cua, roj, roj thiab lwm yam xov xwm nrog rau ib qho tsawg dua lossis sib npaug} {}}} degree ~ 200 degree. Qhov no yog vim tias Grey cam khwb cia hlau tuaj yeem tswj hwm tus qauv nyob rau hauv cov xov xwm, tsis muaj kev tiv thaiv loj lossis tshuaj lom neeg. Txawm li cas los xij, Grey cam khwb cia hlau tsis tiv thaiv muaj zog corrosive media xws li hydrochloric acid thiab nitric acid.
MALLABLE Cam Khwb Cia Hlau Valve
Nws yog qhov haum rau dej, chav dej, huab cua thiab roj nruab nrab nrog nominal siab pn tsawg dua lossis sib npaug thiab kub} ~ 300 degree. Cov tawv thiab cov plasticity ntawm defab camable hlau yog zoo dua rau tias ntawm cov grey cam khwb cia hlau ntawm cov kev ntsuas thiab kub thiab nyob rau hauv cov chaw nruab nrab uas tau piav qhia saum toj no.
Zas Hlau Valve
Nws yog qhov tsim nyog rau dej, chav dej, roj, roj thiab lwm yam xov xwm nrog pn tsawg dua lossis sib npaug} -30 ~ 350 degree. Cov qauv sib txawv ntawm cov hlau sib dhos muab nws cov khoom siv zoo, yog li nws tuaj yeem ua haujlwm relooly thiab kev ua haujlwm.
Pa roj carbon hlau Valve
Nws yog qhov tsim nyog rau dej, chav dej, hydrogen, ammonia, nitroter thiab peprole siab pn tsawg dua lossis sib npaug} {2}} ~ 425 degree. Nyob rau hauv xws li lub siab thiab kub ntau yam, carbon steel hlau li qub yuav tiv thaiv cov siab ntawm nruab nrab, thiab nws tsis yooj yim kom hnov ​​nrog lub nruab nrab, kom ntseeg tau tias qhov siv ntawm lub valve.
COPPER ALSOY Valve
Haum rau pn tsawg dua los yog sib npaug ntawm 2.5Mpa dej, oxygen, roj, roj thiab lwm yam kub ntawm {2}} ~ 250 degree chav nruab nrab. Tooj liab alloys muaj zoo corrosion tsis kam thiab thermal conductivity, tshwj xeeb tshaj yog nyob hauv seawater thiab lwm yam kev tawm tsam.
Kev kub siab tooj liab kub
Haum rau chav thiab roj av roj nrog nominal siab pn tsawg dua los yog sib luag rau 17. {} Mpa thiab kub thiab txias dua lossis sib npaug zos rau 570 degree. Cov khoom kub tooj liab kub tseem tuaj yeem tseem muaj zog ua kom muaj zog thiab ruaj khov nyob rau hauv cov txheej txheem ntawm kev siv kub thiab cua sov thiab roj av.
Tsawg-hlau kub
Haum rau nominal siab pn tsawg dua los yog sib npaug, kub nyob rau {{2} {{2} itrogen, kua nitrogen thiab lwm yam tsawg tshaj xov xwm. Cov hlau kub tsawg los ntawm kev ua tshwj xeeb thiab kev kho cua sov, kom nws muaj kev cuam tshuam zoo thiab tiv thaiv lub valve hauv qhov kub tsawg brittle baritture.
Stainless acid resistrant steel
Haum rau nominal siab pn tsawg dua los yog sib luag rau 6.4MPA, kub tsawg dua lossis sib npaug lossis sib npaug Tus stainless acid-resistant steel muaj cov roj ntsha siab xws li cov duab cheem tsis zoo xws li nitric acid thiab acetic acid thiab acetic acid.
