Muaj ntau ntau cov ntaub ntawv sib txuas rau flanged gate li qub, ntawm cov xov txuas, flange kev twb kev txuas thiab hluav taws xob vuam kev twb kev txuas yog ib qho tseem ceeb txoj kev sib txuas.
Threaded kev twb kev txuas:
Kev sib txuas threaded feem ntau ua rau sab saum toj ntawm qhov nkag thiab qhov hluav taws xob ntawm lub qhov rooj flanged valve rau hauv cov khoom taper yeeb nkab xov los yog ib lub cylindrical sab nraud xov, thiab ceev cov threaded sib koom los yog cov yeeb nkab. Txawm li cas los xij, kev sib txuas threaded tuaj yeem xau thiab yuav tsum tau siv cov khoom siv sealing. Yog tias cov khoom ntawm flanged lub rooj vag valve tuaj yeem welded, nws tuaj yeem raug kaw welded. Txawm li cas los xij, yog tias cov khoom nthuav dav coefficient ntawm cov khoom sib txuas muaj qhov sib txawv loj lossis qhov kub ntawm lub workpiece sib txawv heev, cov xov txuas yuav tsum tau muab khi thiab welded.
Lub flanged rooj vag valve nrog threaded kev twb kev txuas yog haum rau flanged rooj vag li qub nrog ib tug nominal loj nyob rau hauv DN50. Thaum lub nominal loj loj, nws yog ib qho nyuaj rau nruab thiab kaw qhov kev twb kev txuas. Yuav kom yooj yim installation thiab disassembly, ib tug peb-txoj kev sib koom yuav siv tau. Flanged rooj vag li qub nrog lub npe loj hauv DN50 tuaj yeem siv lub qhov (socket) yeeb nkab ua ib qho kev sib koom ua ke, thiab cov xov ntawm cov yeeb nkab txuas txuas ob feem ntawm kev sib txuas.
Flange kev twb kev txuas:
Flange-connected flanged gate li qub yog ib qho yooj yim rau nruab thiab disassemble, thiab tsuas yog haum rau cov yeeb nkab sib txuas nrog cov diameters loj thiab siab dua. Txawm li cas los xij, kev xau tuaj yeem tshwm sim thaum qhov kub siab tshaj 350 degree, yog li tus nqi siab dua.
Vuam kev twb kev txuas:
Hluav taws xob welding welding kev twb kev txuas yog tsuas yog haum rau ntau hnyav thiab kub tej yam kev mob. Nws yog ib qho nyuaj rau disassemble thiab reassemble flanged rooj vag li qub txuas nrog hluav taws xob vuam thiab vuam. Nws yog qhov tsim nyog rau kev ua haujlwm ntev ntev lossis qhov chaw uas muaj kev nyuaj siab thiab kub siab, xws li thermal fais fab chaw nres tsheb, nuclear technology project, thiab butadiene project pipelines.
Welded welded flanged rooj vag li qub nrog nominal loj nyob rau hauv DN5 feem ntau muaj welded sockets, uas muaj peev xwm ua tiav pipelines nrog planar xaus, tab sis qhov sib txawv nto corrosion thiab qaug zog teeb meem yuav tsum tau xav txog nyob rau hauv lub qhov (socket) welding daim ntaub ntawv. Nyob rau hauv cov chaw uas loj nominal loj, siab daim ntawv thov nyuaj thiab kuj kub, weld seam taub qab vuam feem ntau yog siv, thiab vuam yog nruj me ntsis tswj. Thaum xaj, qhov loj ntawm cov yeeb nkab yuav tsum tau qhia kom cov chaw tsim khoom tuaj yeem ua rau lub qhov (socket) thiab vuam zawj raws li qhov loj me.
