Chidziwitso chothandiza cha ma valve

Maziko a valavu
1. Magawo oyambira a valavu ndi awa: kupanikizika kwa dzina PN ndi m'mimba mwake wa dzina DN
2. Ntchito yoyambira ya valavu: kudula cholumikizira cholumikizidwa, kusintha kuchuluka kwa madzi, ndikusintha njira yoyendera madzi
3, njira zazikulu zolumikizira ma valve ndi izi: flange, ulusi, kuwotcherera, wafer
4, kuthamanga kwa valavu —— kutentha kumasonyeza kuti: zipangizo zosiyanasiyana, kutentha kosiyanasiyana kogwira ntchito, kuthamanga kogwira ntchito kosakhudzidwa kwambiri komwe sikuloledwa ndi kosiyana
5. Pali machitidwe awiri akuluakulu a muyezo wa flange: dongosolo la boma la ku Ulaya ndi dongosolo la boma la ku America.
Malumikizidwe a mapaipi a machitidwe awiriwa ndi osiyana kwambiri ndipo sangagwirizane;
Ndikoyenera kwambiri kusiyanitsa ndi mulingo wa kupanikizika:
Dongosolo la boma la ku Ulaya 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 ikuluikulu ya mapaipi a flange ndi: integral (IF), plate flat welding (PL), khosi flat welding (SO), khosi butt welding (WN), socket welding (SW), screw (Th), butt welding ring loose sleeve (PJ / SE) / (LF / SE), flat welding ring loose sleeve (PJ / RJ) ndi flange cover (BL), ndi zina zotero.
Mtundu wa pamwamba pa flange umaphatikizapo makamaka: ndege yonse (FF), pamwamba pa protrusion (RF), pamwamba pa concave (FM) convex (M), pamwamba pa ring connection (RJ), ndi zina zotero.

Ma valve wamba (wamba)
1. Z, J, L, Q, D, G, X, H, A, Y, S motsatana mwa mtundu wa valavu womwe umasonyeza: valavu ya chipata, valavu yoyimitsa, valavu ya throttle, valavu ya mpira, valavu ya gulugufe, valavu ya diaphragm, valavu ya pulagi, valavu yowunikira, valavu yotetezera, valavu yochepetsera kupanikizika ndi valavu yotulutsa madzi.
2, Khodi yolumikizira valavu 1, 2, 4, 6, 7 motsatana inati: ulusi wamkati 1, ulusi wakunja 2, 4-flange, 6-welding, 7-pair clip
3, Njira yotumizira ya khodi ya valavu 9,6,3 motsatana inati: nyongolotsi ya 9-electric, 6-pneumatic, 3-turbine.
4, Khodi ya zinthu za thupi la valve Z, K, Q, T, C, P, R, V motsatana inati: chitsulo chosungunuka cha imvi, chitsulo chosungunuka chosungunuka, chitsulo chosungunuka cha ductile, mkuwa ndi alloy, chitsulo cha carbon, chitsulo chosapanga dzimbiri cha chromium-nickel nickel, chitsulo chosapanga dzimbiri cha chromium-nickel-molybdenum, chitsulo cha chromium-molybdenum vanadium.
5, Chisindikizo cha mpando kapena khodi ya lining R, T, X, S, N, F, H, Y, J, M, W motsatana: chitsulo chosapanga dzimbiri cha austenitic, aloyi yamkuwa, rabara, pulasitiki, pulasitiki ya nayiloni, pulasitiki ya fluorine, chitsulo chosapanga dzimbiri cha Cr, aloyi wolimba, rabala ya lining, aloyi ya moner, zinthu za thupi la valavu.

6. Ndi zinthu zitatu ziti zazikulu zomwe ziyenera kuganiziridwa posankha actuator?
1) Mphamvu yotulutsa ya actuator iyenera kukhala yayikulu kuposa mphamvu ya valavu yowongolera ndipo iyenera kufanana moyenera.
2) Kuti muwone kuphatikiza koyenera, kusiyana kovomerezeka kwa kuthamanga komwe kwatchulidwa ndi valavu yowongolera kumakwaniritsa zofunikira panjira. Mphamvu yosalinganika ya pakati pa valavu iyenera kuwerengedwa panthawi ya kusiyana kwakukulu kwa kuthamanga.
3) Ngati liwiro la yankho la actuator likukwaniritsa zofunikira pa ntchito, makamaka actuator yamagetsi.
7, kampani ya TWS valve ingapereke valavu?
Valavu ya gulugufe yokhala ndi mphira: valavu ya gulugufe wa wafer, valavu ya gulugufe,valavu ya gulugufe ya flangevalavu ya chipata; valavu yowunikira;valavu yolinganiza, valavu ya mpira, ndi zina zotero.
Ku Tianjin Tanggu Water Seal Valve Co., Ltd., timadzitamandira popereka zinthu zapamwamba kwambiri zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani. Ndi ma valve ndi zolumikizira zathu zosiyanasiyana, mutha kutidalira kuti tikupatseni yankho labwino kwambiri la makina anu amadzi. Lumikizanani nafe lero kuti mudziwe zambiri za zinthu zathu komanso momwe tingakuthandizireni.
