Installation thiab disassembly ntawmli qubtxheeb xyuas sab laug thiab sab xis - tes xov
Kev khiav hauj lwm kub ntawm lub valve yog txiav txim los ntawm cov khoom uas lub valve yog ua. Qhov kub ntawm cov khoom siv valve yog raws li nram no:
Lub valve
Kev siv qhov kub thiab txias
Grey hlau valve
-15 ~ 250 ℃
Malleable cam khwb cia hlau valve
-15 ~ 250 ℃
Ductile hlau valve
-30 ~ 350 ℃
High nickel cam khwb cia hlau valve
Qhov siab tshaj plaws ua haujlwm kub yog 400 ℃
Cov pa roj carbon steel valve
-29 ~ 450 ℃, t 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 li qub
-196 ~ 600 ℃
Copper alloy valve
-273 ~ 250 ℃
Plastic Valve (Nylon)
Ua haujlwm kub siab tshaj 100 ℃
Yas valve (chlorinated polyether)
Ua haujlwm kub siab tshaj 100 ℃
Plastic Valve (PVC)
Ua haujlwm kub siab tshaj 60 ℃
Yas valve (polytrifluorovinyl chloride)
-60 ~ 120 ℃
Plastic Valve (PTFE)
-180 ~ 150 ℃
Yas valve (natural roj hmab diaphragm valve)
Ua haujlwm kub siab tshaj 60 ℃
Yas valve (NBR, NEoprene diaphragm valve)
Ua haujlwm kub siab tshaj 80 ℃
Plastic valve (fluorine roj hmab diaphragm valve)
Ua haujlwm kub siab tshaj 200 ℃
Thaum cov roj hmab thiab cov yas siv rau hauv ob sab phlu, qhov kub ntawm cov roj hmab thiab cov yas yuav tsum yeej.
Ceramic valve, vim nws qhov tsis zoo kub tsis kam, feem ntau siv rau hauv kev ua haujlwm hauv qab 150 ℃. Tsis ntev los no, qhov kev ua tau zoo tshaj plaws ceramic valve tau tshwm sim, uas tuaj yeem tiv taus qhov kub thiab txias hauv qab 1000 ℃.
iav valve. Tsis zoo kub tsis kam, feem ntau siv rau kev khiav hauj lwm hauv qab 90 ℃.
Enamel valve, kev ua haujlwm kub yog txwv los ntawm cov khoom siv lub nplhaib sib khi, qhov siab tshaj plaws ua haujlwm kub tsis tshaj 150 ℃.
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 nodular cam khwb cia hlau, R 0Cr12Ni12Mo2 series stainless hlau, RL 00Cr17Ni14Mo2 series stainless hlau, S plastics, T tooj liab thiab tooj liab alloy, Ti titanium thiab titanium alloy, V chromium molybdenum vanadium hlau, Z grey cam khwb cia hlau.
Valve sib dhos thiab disassembly txheeb xyuas sab laug thiab txoj cai xov
Kev txheeb xyuas qhov tseeb tias cov xov yog sab laug lossis sab xis yog qhov kev paub yooj yim tshaj plaws ntawm kev sib dhos valve thiab disassembly. Yog li yuav ua li cas koj thiaj paub tias txoj xov yog sab laug lossis txoj cai?
Nws tuaj yeem txiav txim siab los ntawm cov xov sab hauv lossis sab nraud ntawm lub valve. Feem ntau, lawv yog cov xov zoo thiab tsis zoo siv los tiv thaiv xov loosening. Xws li qia, qia txiv ntoo xov kev sib txuas: lub nplhaib nruj ntawm lub qia txiv ntoo yog sab laug tig, cov xov ntawm lub tes tuav yog txoj kev sib hloov, cov xov trapezoidal ntawm qia txiv ntoo yog sab laug tig. Tsis tas li ntawd, qhov nce lub kaum sab xis ntawm cov xov yog rau sab laug ntawm cov xov yog hu ua sab laug; Txwv tsis pub, nws yog dextral rotation.
