Npauj npaim li qub yog ib hom ntawm lub quarter-tig valve siv los tswj cov dej ntws (kua lossis roj) los ntawm cov kav dej. Lawv ua haujlwm los ntawm kev siv cov hlau disc lossis vane mounted rau ntawm tus pas nrig hauv nruab nrab ntawm cov yeeb nkab. Thaum lub valve raug kaw, lub disc yog perpendicular rau qhov ntws, thaiv nws, thiab thaum lub valve qhib tag nrho, lub disc yog sib npaug rau qhov ntws, tso cai rau tsis muaj kev txwv. Muaj ob hom npauj npaim li qub: lug butterfly li qub thiab wafer npauj npaim li qub. Nov yog qhov sib piv ntawm ob:
Tsim thiab Installation:
Npauj Npaim Valve: Lug-style npauj npaim li qub muaj threaded inserts, hu ua "lugs," ntawm ob sab ntawm lub cev valve. Cov lugs no tso cai rau lub valve rau nruab ntawm ob lub flanges siv bolts. Lub valve tuaj yeem ntsia tau rau hauv ib qho system siv ob txheej ntawm bolts thiab txiv ntseej, tsis tas yuav tsum muaj cov khoom siv ntxiv.
Npauj Npaim Valve: wafer-style npauj npaim li qub tsis muaj lugs. Hloov chaw, lawv muaj lub cev zoo li wafer nrog lub qhov uas sib haum nrog cov yeeb nkab flanges. Lub valve yog muab tso rau ntawm lub flanges, thiab bolts dhau los ntawm lub valve lub cev thiab flanges los tuav tag nrho cov kev sib dhos ua ke. Ib txheej ntawm bolts thiab ceev yog xav tau rau kev teeb tsa.
Daim ntawv thov Installation:
Lug Npauj Npaim Valve: Lug-style li qub yog siv rau hauv cov ntawv thov uas cov kav dej yuav tsum tau muab lub valve rau nruab thiab tshem tawm yam tsis muaj kev cuam tshuam tag nrho cov kav dej. Qhov no yog vim hais tias lug li qub tau yooj yim ntsia los yog tshem tawm ntawm lub system siv cov threaded lugs.
Wafer Npauj Npaim Valve: Wafer-style li qub feem ntau yog siv rau hauv cov ntawv thov nrog qhov chaw txwv. Lawv yog cov compact thiab sib dua nyob rau hauv hnyav piv rau lug li qub, ua rau lawv haum rau installation qhov chaw yog ib tug txwv.
Kev ntsuas siab:
Lug Npauj Npaim Valve: Lug-style li qub muaj qhov ntsuas siab dua piv rau wafer-style li qub. Cov lugs muab kev txhawb nqa ntxiv thiab tso cai rau lub valve los tswj cov kev kub siab dua.
Wafer Npauj Npaim Valve: Wafer-style li qub muaj qhov ntsuas qis qis dua piv rau cov qauv li qub. Lawv feem ntau tsim nyog rau cov ntawv thov nrog kev xav tau qis dua.
Lub ntsej muag-rau-Face Dimensions:
Lug Npauj Npaim Valve: Lug-style li qub muaj lub ntsej muag-rau-lub ntsej muag, uas txhais tau hais tias lawv muaj qhov ntev ntev ntawm ib kawg mus rau lwm qhov. Qhov loj me no yog qhov tseem ceeb rau kev txhim kho kom zoo hauv cov kav dej.
Wafer Npauj Npaim Valve: Wafer-style li qub muaj lub ntsej muag luv luv piv rau cov qauv li qub. Qhov kev tsim compact no ua rau lawv nyiam xaiv hauv qhov chaw nruj.
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm lub lug npauj npaim valve thiab wafer npauj npaim valve yog nyob rau hauv lawv cov qauv tsim, kev teeb tsa, kev ntsuas siab, thiab qhov ntev ntawm lub ntsej muag. Qhov kev xaiv ntawm ob hom yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov, qhov chaw muaj, thiab cov kev mob siab.
