Stainless hlau wafer nqa check valve H71W/stainless hlau ib-txoj kev valve / wafer nqa tsis rov qab valveadopts luv qauv loj thiab ib tug disc tsim.Piv nrog rau kev sib tw viav vias ib txwm siv, cov khoom siv ntawm cov li qub no tsis muaj qhov cuam tshuam sab nraud, tuaj yeem ntsia tau rau hauv txhua txoj haujlwm, kev sib khi zoo, tsis tshua muaj kev vibration, tsis tshua muaj siab poob thiab xoom lub nplhaib hnav zoo.Nws lub luag haujlwm tseem ceeb yog qhov dej rauj siab me me, lub valve nrov plig plawg stroke luv luv, lub valve nrov plig plawg yog lub teeb, nrog lub caij nplooj ntoos hlav pab kaw, thiab lub valve kaw nrawm heev.Cov qauv yog luv luv, me me, thiab lub teeb nyob rau hauv qhov hnyav, uas coj tau yooj yim mus rau lub valve installation, tsheb thauj mus los, cia thiab kev npaj pipeline.
Txoj haujlwm ua haujlwm:
Lub valve nrov plig plawg yog positioned raws qhov nruab nrab kom txav mus los thiab nqis.Vim yog luv luv kaw stroke ntawm lub valve nrov plig plawg thiab lub caij nplooj ntoos hlav loading, kaw ceev ceev, uas yuav txo tau cov dej rauj tshwm sim.Cov khoom muaj cov yam ntxwv ntawm me me, lub teeb yuag, rhiab heev, txhim khu kev qha sealing, thiab yooj yim installation.Nws yog tshwj xeeb tshaj yog haum rau lub sij hawm uas qhov chaw installation yog txwv.
Nta:
1. Lub valve nrov plig plawg kaw sai thiab cov dej rauj siab me me.
2. Nws muaj cov qauv luv, me me thiab lub teeb yuag.
3. Lub ntws channel yog unobstructed, cov kua kuj yog me me;qhov kev txiav txim yog rhiab heev, thiab sealing kev ua tau zoo.
4. Vim muaj qhov ceev ceev, nws tuaj yeem tiv thaiv qhov nruab nrab ntawm ntws rov qab thiab tshem tawm cov dej rauj.
5. Yooj yim rau nruab, nws tuaj yeem ntsia tau rau hauv cov kav dej hauv ob qho tib si kab rov tav thiab ntsug.
6. Lub valve phaj txais tus qauv tsim ntawm kev ntxiv ob lub torsion springs ntawm mating phaj, uas tuaj yeem ua rau lub valve phaj nws tus kheej ceev ceev.
Scope ntawm kev siv:
Nws yog haum rau ntau yam kav dej nrog nominal siab PN1.6Mpa ~ 42.0Mpa, Class150 ~ 2500LB;nominal txoj kab uas hla DN15 ~ 1200mm, PNS1 / 2 ~ 48 ";Ua haujlwm kub: -196 ~ 540 ℃, siv los tiv thaiv qhov nruab nrab rov qab.Valve.Cov khoom siv hauv lub cev yog: carbon steel, stainless hlau, thiab lwm yam, uas tuaj yeem siv rau dej, chav dej, roj, roj, acid media, thiab lwm yam.
