U Hom Npauj Npaim Valve

Kev Piav Qhia Luv:

Lubob chav flanged U-hom npauj npaim valvesib koom tib lub concentric resilient-seated kev tsim kho zoo li hom wafer, tab sis muaj cov flanges integral ntawm ob qho kawg rau kev sib dhos flange meej thiab yooj yim dua rau kev teeb tsa. Lub rooj zaum roj hmab yog vulcanized tag nrho ncaj qha rau ntawm lub cev, ua kom muaj lub foob nruj, ruaj khov yam tsis muaj cov khoom sib cais. Tsim los rau API 609 / EN 593, qhov loj me DN350–DN1200 (14″–48″), qhov ntsuas siab PN10 / PN16 / PN25 thiab ANSI Class 125/150. Nortech yog lub tuam txhab ua U-type butterfly valve tsim khoom thiab muag khoom hauv Suav teb.

Tus qauv flange sib xyaw ua ke tshem tawm qhov xav tau cov flange adapters, txo lub sijhawm teeb tsa thiab qhov kev pheej hmoo ntawm kev tsis sib haum - tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov kav dej loj hauv cov dej, kev ywg dej, thiab cov txheej txheem kev lag luam. Lub cev thiab disc muaj nyob rau hauv cov hlau ductile, carbon hlau, stainless hlau, thiab alu-bronze kom haum rau cov xov xwm corrosive lossis demanding. Cov ntaub ntawv rooj zaum suav nrog EPDM, NBR, FKM, thiab silicone, npog ntau yam kub thiab hom kua. ISO 5211 sab saum toj flange ua kom ntseeg tau tias muaj kev sib raug zoo ncaj qha nrog phau ntawv, hluav taws xob, thiab pneumatic actuators. Txhua lub valve raug sim thiab tshuaj xyuas rau API 598 / EN 12266.

Ob Chav Flanged U-Type Butterfly Valve — Kev Qhia Ua Ntej

Dab tsi yog ob chav flanged U-Type npauj npaim valve?

Lubob chav flanged U-hom npauj npaim valveyog lub valve uas ruaj khov thiab zaum tau zoo - tseem hu ua "concentric", "rubber lined", lossis "rubber seated" butterfly valve. Nws muaj lub rooj zaum roj hmab uas ruaj khov thiab vulcanized ncaj qha rau ntawm lub cev, ntawm qhov txoj kab uas hla sab nraud ntawm lub disc thiab phab ntsa sab hauv ntawm lub valve, ua kom ntseeg tau tias muaj kev sib khi zoo thiab ruaj khov rau ntau yam kev siv.

Ib lub valve uas tig ib feem plaub uas tig 90° kom qhib lossis kaw tag nrho cov dej ntws. Lub disc ncig - uas tau teeb tsa rau hauv nruab nrab ntawm lub cev valve - ua haujlwm ua lub tshuab kaw tseem ceeb, txuas nrog lub actuator lossis kov ntawm lub qhov hauv nruab nrab. Thaum lub disc tig tag nrho 90-degree, lub valve ua haujlwm ua ib qholub vaus kawThaum qhib ib nrab, nws ua haujlwm ua ib qholub valve tswj kev ntws, tso cai rau kev tswj hwm meej ntawm ntau lub kaum qhib.

Hais txog txoj kev teeb tsa, U-hom yog cais ua awafer-hom valveTxawm hais tias nws muaj ob lub flanges sib xyaw ua ke rau ntawm lub cev, nws qhov ntev ntawm lub ntsej muag yog tib yam li hom wafer txheem - compact hauv kev tsim, haum ntawm ob lub raj xa dej flanges nrog studs hla dhau los ntawm ib sab mus rau lwm qhov. Lub valve tau tuav rau hauv qhov chaw thiab kaw los ntawm gaskets nyob rau hauv stud tension. Cov flanges sib xyaw ua ke tau tsim tshwj xeeb los pab sib phim thiab teeb tsa, ua qhov kev teeb tsa no yog qhov kev xaiv zoo tshaj plaws rau cov yeeb nkab loj dua.

Ntawm Nortech, cov npauj npaim uas muaj zog nyob hauv hom wafer thiab hom lug npog DN32–DN600. Rau cov kab uas loj dua, siv U-hom flanged npauj npaim valve - muab tib lub rooj zaum uas muaj zog uas tau ua pov thawj hauv qhov ntau thiab tsawg DN350–DN1200 (14″–48″).

Daim ntawv qhia CV/KV ntawm lub qhov rooj zaum tawv uas muaj zog U-hom muaj nyob rau ntawm qhov kev thov.

U-Hom vs. Wafer vs. Ob Chav Flanged— peb hom kev teeb tsa sib koom ua ke tib lub qauv ruaj khov tab sis txawv ntawm lawv txuas rau cov kav dej. Qhov kev sib piv hauv qab no qhia txog qhov sib txawv tseem ceeb hauv kev sib txuas kawg thiab txoj kev teeb tsa.
