Wafer npauj npaim li qubthiabflange npauj npaim li qubyog ob hom npauj npaim li qub.Ob hom npauj npaim li qub muaj ntau yam kev siv, tab sis ntau tus phooj ywg tsis tuaj yeem paub qhov txawv ntawm wafer butterfly li qub thiab flanged npauj npaim li qub, thiab lawv tsis paub qhov txawv ntawm ob.
Npauj npaim valve lub wafer thiab flange yog ob txoj kev sib txuas.Hais txog tus nqi, hom wafer kuj pheej yig dua, tus nqi yog kwv yees li 2/3 ntawm flange.Yog tias koj xav xaiv cov khoom siv txawv teb chaws, siv hom wafer kom ntau li ntau tau, uas yog pheej yig thiab lub teeb hauv qhov hnyav.
Wafer hom li qub muaj cov bolts ntev dua thiab xav tau kev tsim kho ntau dua.Yog hais tias lub flanges ntawm ob sab tsis sib haum, lub bolts yuav raug ntau dua shearing quab yuam, thiab lub valve yog feem ntau to.
Wafer hom npauj npaim valve bolts feem ntau kuj ntev.Nyob rau hauv qhov kub thiab txias, qhov kev nthuav dav ntawm lub ntsia liaj qhov rooj yuav ua rau kom tawg, yog li nws tsis haum rau cov yeeb nkab loj diameters nyob rau hauv qhov kub thiab txias.Tsis tas li ntawd, wafer npauj npaim li qub feem ntau tsis tuaj yeem siv thaum kawg ntawm cov kav dej thiab cov dej hauv qab uas nws yuav tsum tau disassembled, vim tias thaum lub flange downstream disassembled, lub wafer valve yuav poob.Hauv qhov no, ib qho luv luv yuav tsum tau ua nyias nyias.Yuav kom disassemble, thiab flange hom npauj npaim valve tsis muaj teeb meem saum toj no, tab sis tus nqi yuav siab dua.
Lub wafer npauj npaim valve tsis muaj flanges ntawm ob qho kawg ntawm lub cev lub cev, tsuas yog ob peb phau ntawv qhia lub qhov taub, thiab lub valve txuas nrog lub flanges ntawm ob qho kawg los ntawm ib txheej ntawm bolts / ceev.Nyob rau hauv sib piv, disassembly yog yooj yim dua, thiab lub valve tus nqi qis dua, tab sis qhov tsis zoo yog tias ib qho sealing nto muaj teeb meem, thiab ob qho tib si sealing nto yuav tsum tau disassembled.
Lub flange hom npauj npaim valve muaj flanges ntawm ob qho kawg ntawm lub cev lub cev, uas txuas nrog cov yeeb nkab flange, thiab lub sealing kuj tseem txhim khu kev qha, tab sis lub valve raug nqi kuj siab.
