Imibuzo Evame Ukubuzwa (Imibuzo Evame Ukubuzwa)
Yebo, kodwa kunemikhawulo ethile. Amavalvu e-butterfly asebenza kahle kakhulu ahlinzeka ngezici zokugeleza okuqondile kuwo wonke ama-degree angu-90 okujikeleza, okwenza afanelekele izinhlelo zokulawula ezishintshayo. Kodwa-ke, ukugoqa ezindaweni ezivulekile eziphansi kakhulu (ngaphansi kuka-15-20%) noma ezingcindezini eziphakeme zomehluko kungaholela ekugoqeni kwe-liquid service. Amavalvu e-triple offset ahlinzeka ngokusebenza okuphezulu kokugoqa ngenxa yesilinganiso sawo sokulawula esiphezulu. Ukuze uthole ukulawula okunembile kokugoqa, bheka ama-curve okugeleza (i-Cv) omenzi kanye nedatha ye-cavitation yosayizi wevalvu ethile kanye nokusika.
Isitayela se-wafer:Ivalvu iboshwe phakathi kwama-flange amabili epayipi. Lokhu kuyindlela engabizi kakhulu kodwa ayivumeli ukususwa kwamapayipi angaphansi komfula ngaphandle kokucindezela uhlelo. Amavalvu e-Wafer ashibhile ngo-20-40% kunamavalvu e-lug anobukhulu obufanayo.
Isitayela se-Lug:Umzimba wevalvu unezifakelo ezinezintambo (ama-lug) kuzo zombili izinhlangothi, okuvumela ukubhoboza kuma-flange kuzo zombili izinhlangothi ngokuzimela. Lokhu kwenza isevisi engapheli, okusho ukuthi amapayipi angaphansi komfula angasuswa ngenkathi uhlangothi oluphezulu luhlala lucindezelwe—okubalulekile ekufinyeleleni kokulungiswa. Amavalvu e-Lug nawo anikeza amandla engeziwe okusebenza ezinhlelweni ezingaphansi kokucindezeleka kwephayiphi.
Zombili izitayela ziyatholakala ngezindlela zokuvala eziqondene nezinhlangothi ezimbili.
Khetha i-triangle offset uma:
- Izinga lokushisa lidlula ama-260°C (umkhawulo osebenzayo wezihlalo ze-PTFE/RPTFE)
- Uhlelo lokusebenza ludinga ukuvala kwensimbi kusuka kunsimbi kuya kunsimbi okungavuzi lutho
- Isevisi ihilela ukuhlukaniswa komusi okushisa okuphezulu noma i-hydrocarbon lapho ukuphepha komlilo kuyimpoqo
- Ukubalwa komjikelezo ophezulu kudinga ukumelana okukhulu kokugqokwa
- Ivalvu isetshenziswa ekuhlinzekeni nge-cryogenic (i-LNG, i-ethylene)—amavalvu amathathu ahlanganisiwe anezinto ezifanele asebenza ngokuthembeka emazingeni okushisa aphansi kakhulu.
Khetha i-double offset (ukusebenza okuphezulu okujwayelekile) uma:
- Izinga lokushisa lingaphansi kuka-260°C
- Izihlalo ze-PTFE noma ze-PTFE eziqinisiwe zinikeza ukuhambisana okwanele kwamakhemikhali
- Impilo yomjikelezo omaphakathi (amashumi ezinkulungwane zemijikelezo) ihlangabezana nezimfuneko
- Izindleko zokuqala eziphansi ziyinto eza kuqala
Ukuhlolwa okuzimele kubonise ukuvalwa okuqinile kwama-bubble ngemijikelezo engaphezu kuka-100,000 yama-valve e-butterfly asebenza kahle kakhulu aphindwe kabili. Ama-valve e-offset amathathu, anezihlalo zawo zensimbi kanye ne-geometry yokuvala engenakuphikiswana, angafeza izimpilo zesevisi ezinde nakakhulu—ngokuvamile adlula imijikelezo engu-250,000 ezimweni zesevisi eziphakathi nendawo. Impilo yangempela yomjikelezo incike ezimweni zokusebenza, kufaka phakathi ingcindezi, izinga lokushisa, ukuhlanzeka koketshezi, kanye nesivinini sokusebenza.
Cha. Inzuzo ebalulekile yomklamo osebenza kahle kakhulu ikhono langempela lokuvala izinhlangothi zombili. Ngokungafani nama-valve amaningi e-concentric butterfly, angase abe nesiqondiso sokugeleza esithandwayo esigxivizwe emzimbeni, ama-valve asebenza kahle agcina ukusebenza okugcwele kokuvala kungakhathalekile ukuthi ukufakwa kuqondiswa kuphi. Lokhu kwenza kube lula ukufakwa futhi kunciphisa ingozi yokufakwa okungalungile.
