Valve foundation
1. Cov yam ntxwv ntawm lub valve yog: nominal siab PN thiab nominal txoj kab uas hla DN
2. Cov haujlwm tseem ceeb ntawm lub valve: txiav tawm qhov nruab nrab txuas, kho tus nqi ntws, thiab hloov cov kev taw qhia ntws
3, txoj hauv kev tseem ceeb ntawm kev sib txuas valve yog: flange, xov, vuam, wafer
4, lub siab ntawm lub valve —— qhov kub thiab txias qhia tau hais tias: cov khoom sib txawv, qhov sib txawv ua haujlwm kub, qhov siab tshaj plaws uas tsis muaj kev cuam tshuam kev ua haujlwm siab sib txawv.
5. Muaj ob lub ntsiab ntawm cov qauv flange: European xeev system thiab American xeev system.
Cov yeeb nkab flange kev sib txuas ntawm ob lub tshuab yog sib txawv kiag li thiab tsis tuaj yeem sib tw;
Nws yog qhov tsim nyog kom paub qhov txawv ntawm qib siab:
European lub xeev system yog PN0.25,0.6, 1.0, 1.6, 2.5, 4.0, 6.3, 10.0, 16.0, 25.0, 32.0, 40.0MPa;
US lub xeev system yog PN1.0 (CIass75), 2.0 (CIass150), 5.0 (CIass300), 11.0 (CIass600), 15.0 (CIass900), 26.0 (CIass1500), 42.0 (CIass2500) MPa.
Lub ntsiab hom yeeb nkab flange yog: ib qho (IF), phaj tiaj vuam (PL), caj dab tiaj vuam (SO), caj dab taub qab vuam (WN), lub qhov (SW), ntsia hlau (Th), taub qab vuam nplhaib xoob lub tes tsho. (PJ / SE) / (LF / SE), welding nplhaib xoob lub tes tsho (PJ / RJ) thiab flange npog (BL), thiab lwm yam.
Flange sealing nto hom feem ntau suav nrog: tag nrho dav hlau (FF), protrusion nto (RF), concave (FM) convex (M) nto, nplhaib sib txuas nto (RJ), thiab lwm yam.
Common (common) li qub
1. Z, J, L, Q, D, G, X, H, A, Y, S raws li lub valve hom code qhia: rooj vag valve, nres valve, throttle valve, pob valve, npauj npaim valve, diaphragm valve, ntsaws valve, kos valve, kev ruaj ntseg valve, siab txo valve thiab ntws valve.
2, Lub valve kev twb kev txuas hom code 1,2,4,6,7 raws li hais: 1-internal xov, 2-sab xov xov, 4-flange, 6-welding, 7-pair clip
3, Kev sib kis ntawm lub valve code 9,6,3 raws li tau hais tias: 9-hluav taws xob, 6-pneumatic, 3-turbine worm.
4, Lub valve lub cev cov ntaub ntawv code Z, K, Q, T, C, P, R, V raws li hais tias: grey cam khwb cia hlau, malleable cam khwb cia hlau, ductile cam khwb cia hlau, tooj liab thiab alloy, carbon hlau, chromium-nickel nickel stainless hlau , chromium-nickel-molybdenum stainless hlau, chromium-molybdenum vanadium hlau.
5, Seat seal lossis hauv ob sab phlu code R, T, X, S, N, F, H, Y, J, M, W feem: austenitic stainless hlau, tooj liab alloy, roj hmab, yas, nylon yas, fluorine yas, Cr stainless hlau , nyuaj alloy, hauv ob sab phlu roj hmab, moner alloy, valve lub cev khoom.
6. Peb yam tseem ceeb twg yuav tsum tau xav txog hauv kev xaiv tus actuator?
1) Cov zis ntawm lub actuator yuav tsum ntau tshaj qhov load ntawm lub regulating valve thiab yuav tsum tau sib haum xeeb.
2) Txhawm rau txheeb xyuas cov qauv kev sib xyaw ua ke, qhov kev tso cai sib txawv tau teev tseg los ntawm kev tswj lub valve ua tau raws li cov txheej txheem yuav tsum tau ua. Lub zog tsis sib npaug ntawm lub valve tseem ceeb yuav tsum tau xam thaum lub sij hawm sib txawv loj.
3) Seb cov lus teb ceev ntawm tus actuator ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem kev ua haujlwm, tshwj xeeb tshaj yog cov hluav taws xob actuator.
7, TWS valve tuam txhab tuaj yeem muab lub valve muaj?
Roj hmab zaum npauj npaim valveTug: Npauj Npaim Npauj Npaim Valve, Npauj Npaim Npauj Npaim Valve,flange npauj npaim valve; rooj vag valve; kos valve;ntsuas valve, pob valve, thiab lwm yam.
Ntawm Tianjin Tanggu Dej Foob Valve Co., Ltd., peb txaus siab rau peb tus kheej ntawm kev muab cov khoom lag luam thawj zaug uas ua tau raws li cov qauv kev lag luam siab tshaj plaws. Nrog peb ntau yam ntawm li qub thiab fittings, koj tuaj yeem ntseeg peb los muab cov kev daws teeb meem zoo tshaj plaws rau koj qhov dej. Tiv tauj peb hnub no kom paub ntau ntxiv txog peb cov khoom thiab peb tuaj yeem pab koj li cas.
