I-Flanged (Fixed) Ball Valve

Uhlolojikelele Lomkhiqizo

I-valve yebhola ye-Q47 ehleliwe uma iqhathaniswa ne-valve yebhola elintantayo, iyasebenza, ingcindezi yoketshezi phambi kwendawo yonke idluliselwa kumandla okuthwala, ngeke yenze i-sphere esihlalweni ukuze ihambe, ngakho isihlalo ngeke sithwale futhi. ukucindezela okukhulu, ngakho-ke i-torque ye-valve yebhola engaguquki incane, isihlalo se-deformation encane, ukusebenza kokuvalwa okuzinzile, impilo ende yesevisi, esebenza ekucindezelweni okuphezulu, ububanzi obukhulu. .I-valve ngayinye inezihlalo ezimbili futhi ingavaleka ohlangothini ngalunye, ngaleyo ndlela ukufakwa akunamingcele yokugeleza.Ingabe isizukulwane esisha se-valve yebhola esebenza kahle, i-valve yebhola eqinile ye-flange ifanele amapayipi amade namapayipi ezimboni jikelele, amandla ayo, ukuphepha. , ukumelana nemvelo enokhahlo ekwakhiweni kokucatshangelwa okukhethekile, okulungele imidiya ehlukahlukene ebolayo nengenakonakala.
Isimiso sokusebenza se-valve yebhola engashintshi:
Ibhola le-valve ye-valve egxiliwe ene-flanged igxilile futhi isekelwa izintambo ezimbili ezihleliwe ezixhunywe ebhola.Uma ivaliwe, ngaphansi kwesenzo sokucindezela okuphakathi, ibhola ngeke likhiqize ukufuduka, ngokuvamile elixhunywe nebhola ku-shaft engenhla, ephansi. i-shaft ifakwe ama-bearing bearings, noma ama-sliding bearings.Ukunciphisa ukungqubuzana kwejenali lapho uvula noma uvala.Yehlisa i-torque yokusebenza.Le valve yebhola engashintshi ifanele ama-valve amabhola amakhulu.Q47 Ibhola eliqinile le-valve yebhola eqinile.Yamukela phezulu nangaphansi Iziqu ezimbili ze-valve zilungisiwe.Lapho kusebenza, ukucindezela koketshezi ngeke kwenze ibhola liye ekunyakazeni kwesihlalo se-valve, isihlalo se-valve ngeke sithwale ukucindezela okukhulu nokuguqulwa.Ingxenye ye-valve stem ifakwe ama-self-lubricating bearings ukunciphisa ukungqubuzana, kanye i-torque yokushintsha incane. Zombili izihlalo zamavalvu zilayishwa kuqala intwasahlobo.Uphawu lwamukela i-PTFE efakwe esibambi sensimbi, futhi isiphethu sinikezwa ngemuva kwendandatho yensimbi ukuze kuqinisekiswe ukuthi isihlalo se-valve siseduze nebhola.Lapho ingcindezi egunjini levalvu inyuka. ngendlela engavamile futhi idlula amandla e-spring jacking, isihlalo se-valve siyahoxiswa ebholeni ukuze kuzuzwe umphumela wokukhululeka kokucindezela okuzenzakalelayo, futhi isihlalo se-valve sisethwa kabusha ngokuzenzakalelayo ngemva kokucindezela. -ukonga nokuphila isikhathi eside. Ilungele kakhulu ipayipi lebanga elide kanye nepayipi elijwayelekile.
