Kudziwa bwino mavavu

Vavu maziko
1. Zofunikira za valve ndi: kuthamanga kwadzina PN ndi m'mimba mwake DN
2. Ntchito yoyambira ya valve: dulani cholumikizira cholumikizidwa, sinthani kuthamanga, ndikusintha njira yolowera
3, njira zazikulu zolumikizira valavu ndi: flange, ulusi, kuwotcherera, mkate
4, kuthamanga kwa valavu -- kutentha kwa mlingo kumasonyeza kuti: zipangizo zosiyanasiyana, kutentha kwa ntchito zosiyanasiyana, pazipita amaloledwa palibe kukhudza kugwira ntchito ndi osiyana
5. Pali machitidwe awiri akuluakulu a flange standard: European state system ndi American state system.
Kulumikizana kwa chitoliro kwa machitidwe awiriwa ndi osiyana kwambiri ndipo sikungafanane;
Ndikoyenera kwambiri kusiyanitsa ndi kuchuluka kwa kuthamanga:
European state system ndi PN0.25,0.6, 1.0, 1.6, 2.5, 4.0, 6.3, 10.0, 16.0, 25.0, 32.0, 40.0MPa;
Dongosolo la boma la US ndi PN1.0 (CIass75), 2.0 (CIass150), 5.0 (CIass300), 11.0 (CIass600), 15.0 (CIass900), 26.0 (CIass1500), 42.0 (CIass2500) MPa.
Mitundu yayikulu ya flange ya chitoliro ndi: chophatikizika (IF), kuwotcherera lathyathyathya (PL), kuwotcherera khosi lathyathyathya (SO), kuwotcherera khosi matako (WN), kuwotcherera zitsulo (SW), wononga (Th), matako kuwotcherera mphete (PJ / SE) / (LF / SE), mphete yowotcherera yosalala (PJ / RJ) ndi chivundikiro cha flange (BL), ndi zina.
Mtundu wosindikiza wa Flange umaphatikizapo: ndege yonse (FF), protrusion surface (RF), concave (FM) convex (M) pamwamba, ring connection surface (RJ), etc.

Ma valve wamba (wamba).
1. Z, J, L, Q, D, G, X, H, A, Y, S motsatira malamulo amtundu wa valavu amasonyeza: valavu yachipata, valavu yoyimitsa, valve yothamanga, valavu ya mpira, valavu ya butterfly, valve diaphragm, pulagi valavu, valavu yowunikira, valavu yotetezera, valve yochepetsera kuthamanga ndi valavu yokhetsa.
2, mtundu wolumikizira ma valve 1,2,4,6,7 motsatana adati: ulusi wamkati wa 1, ulusi wa 2 wakunja, 4-flange, 6-kuwotcherera, clip-7
3, Njira yotumizira ma valve code 9,6,3 motsatana adati: 9-electric, 6-pneumatic, 3-turbine worm.
4, valavu thupi zakuthupi kachidindo Z, K, Q, T, C, P, R, V motero anati: imvi kuponyedwa chitsulo, malleable kuponyedwa chitsulo, ductile kuponyedwa chitsulo, mkuwa ndi aloyi, mpweya zitsulo, chromium-nickel faifi tambala zitsulo zosapanga dzimbiri. , chromium-nickel-molybdenum chitsulo chosapanga dzimbiri, chromium-molybdenum vanadium chitsulo.
5, Mpando chisindikizo kapena akalowa kachidindo R, T, X, S, N, F, H, Y, J, M, W motero: austenitic zosapanga dzimbiri zitsulo, aloyi mkuwa, mphira, pulasitiki, nayiloni pulasitiki, fluorine pulasitiki, Cr zosapanga dzimbiri zitsulo. , aloyi yolimba, mphira wokhazikika, aloyi ya moner, mavavu amthupi.

6. Kodi ndi zinthu zitatu ziti zazikulu zimene tiyenera kuziganizira posankha choyatsira?
1) Kutulutsa kwa actuator kudzakhala kwakukulu kuposa katundu wa valve yoyendetsa ndipo kudzakhala kofanana.
2) Kuti muwone kusakanikirana koyenera, kusiyana kovomerezeka kovomerezeka komwe kumatchulidwa ndi valve yolamulira kumakwaniritsa zofunikira. Mphamvu yosagwirizana yapakati ya valve iyenera kuwerengedwa panthawi ya kusiyana kwakukulu kwa kuthamanga.
3) Kaya liwiro loyankhira la actuator likukwaniritsa zofunikira pakugwira ntchito, makamaka chowongolera magetsi.
7, TWS vavu kampani angapereke valavu ali?
Vavu yagulugufe yokhala ndi mphira: valavu ya butterfly, valve butterfly valve,valavu ya butterfly ya flange; valve pachipata; valve valve;valve balancing, valavu ya mpira, etc.
Ku Tianjin Tanggu Water Seal Valve Co., Ltd., timanyadira popereka zinthu zapamwamba zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani. Ndi ma valve athu osiyanasiyana ndi zomangira, mutha kutikhulupirira kuti tikupatsani yankho labwino kwambiri pamadzi anu. Lumikizanani nafe lero kuti mudziwe zambiri zazinthu zathu komanso momwe tingakuthandizireni.
