I-ASME Globe Valve
Iyini i-ASME Globe Valve?
Ama-valve e-globe angama-valve okuvala ahamba kancane asetshenziselwa ukuqala, ukumisa noma ukulawula ukugeleza kusetshenziswa ilungu lokuvala elibizwa ngokuthi i-disc. Isihlalo se-valve ye-globe siphakathi nendawo futhi sihambisana nepayipi, futhi imbobo esihlalweni ivaliwe ngediski noma ipulaki. I-valve ye-globe disc ingavala ngokuphelele indlela yokugeleza noma ingasuswa ngokuphelele. Imbobo yesihlalo iyashintsha ngokulinganayo ngokuhamba kwediski okulungele imisebenzi ehilela ukulawulwa kokugeleza. Ama-valve e-globe afaneleka kakhulu futhi asetshenziswa kabanzi ukulawula noma ukumisa ukugeleza koketshezi noma igesi ngepayipi ukuze kucindezelwe futhi kulawulwe ukugeleza koketshezi futhi ngokuvamile asetshenziswa kumapayipi amancane.
I-valve ye-ASME Globeingenye yemiklamo ethandwa kakhulu yama-globe valve, yesistimu yase-US kanye ne-API. ububanzi bangaphakathi, izinto zokwakha, ubuso nobuso, ukujiya kodonga, izinga lokushisa lokucindezela, kuchazwe yi-ASME B16.34.
Ngaphezu kwalokho, kuye ngomklamo wesihlalo kanye nediski, umthwalo wezihlaloAmavalvu embulunga ye-ASMEingalawulwa kahle ngesiqu esinesikulufo. Amandla okuvalaI-valve yomhlaba wonke ye-ASMEkuphezulu kakhulu. Zingasetshenziswa emsebenzini wokuvala. Ngenxa yebanga elifushane lokuhamba kwediski phakathi kwezindawo ezivulekile nezivaliwe,Amavalvu embulunga ye-ASMEzilungele uma ivalvu kufanele ivulwe futhi ivalwe njalo. Ngakho-ke, amavalvu agcwele angasetshenziswa emisebenzini eyahlukahlukene.
iAmavalvu e-ASME Globeingasetshenziswa futhi ngezinjongo zokubhoboza. Imizimba eminingi yamavalvu ahlala yedwa isebenzisa ukwakhiwa kwekheji noma isitayela sokugcina ukuze igcine indandatho yesihlalo, inikeze ukuqondisa kwepulaki yamavalvu, futhi inikeze indlela yokusungula izici ezithile zokugeleza kwamavalvu. Ingashintshwa kalula ngokushintsha izingxenye zokusika ukuze ishintshe isici sokugeleza noma inikeze amandla ancishisiwe.ukugeleza, ukunciphisa umsindo, noma ukunciphisa noma ukususa i-cavitation.
Amaphethini Omzimba We-ASME Globe Valve, kunezinhlobo ezintathu eziyinhloko zomzimba noma imiklamo yama-valve e-Globe, okuyilezi:
- 1). Iphethini Ejwayelekile (eyaziwa nangokuthi i-Tee Pattern noma i-T – Iphethini noma i-Z – Iphethini)
- 2). Iphethini ye-Angle
- 3). Iphethini Eligobile (elaziwa nangokuthi i-Wye Pattern noma i-Y – Pattern)
Isimiso Sokusebenza seI-ASME Globe Valve
I-globe valve yakhiwe yidiski ehambayo kanye nesihlalo sendandatho esingaguquki emzimbeni oyindilinga. Isihlalo se-globe valve siphakathi nendawo futhi sihambisana nepayipi, futhi imbobo esihlalweni ivaliwe ngediski. Uma isondo lesandla lijikeleziswa ngesandla noma nge-actuator, ukunyakaza kwediski kulawulwa (kwehliswa noma kuphakanyiswe) ngesiqu se-valve. Lapho i-globe valve disc ihlezi phezu kwendandatho yesihlalo, ukugeleza kuyamiswa ngokuphelele.
Isici esiyinhloko se-ASME Globe valve
- 1) .Amakhono okuhle okubopha uphawu
- 2). Ibanga elifushane lokuhamba kwediski (stroke) phakathi kwezikhundla ezivulekile nezivaliwe,Amavalvu embulunga ye-ASMEzilungele uma ivalvu kufanele ivulwe futhi ivalwe njalo;
- 3).I-valve ye-ASME globe ingasetshenziswa njenge-valve yokuhlola ukuthi imisa nini ngokushintsha umklamo kancane.
- 4).TNansi amakhono ahlukahlukene njengoba etholakala ngezitayela ze-tee, i-Wye, kanye ne-angle body.
- 5).Kulula ukukhanda nokulungisa izihlalo, ngezinhloso ezahlukene.
- 6).Ikhono lokugoqa eliphakathi nendawo kuya kwelihle, ngokushintsha isakhiwo sesihlalo nediski.
- 7).Buphawu lwe-ellows luyatholakala uma luceliwe.

Ukusetshenziswa kwama-valve e-ASME Globe
I-ASME Globe Valveisetshenziswa kabanzi ezinsizeni eziningi ezahlukene; kokubili izinsizakalo zomfutho ophansi kanye noketshezi oluphezulu. Ukusetshenziswa okujwayelekile kwama-globe valve yilokhu:
- 1). Yakhelwe ipayipi elivamise ukuvalwa, noma ukugoqa uketshezi kanye negesi ephakathi nendawo
- 2). Uketshezi: Amanzi, umusi, umoya, uphethiloli ongahluziwe kanye nemikhiqizo kaphethiloli, igesi yemvelo, igesi econdensate, izixazululo zobuchwepheshe, umoya-mpilo, amagesi aketshezi kanye nalawo angenamandla
- 3).Izinhlelo zamanzi okupholisa ezidinga ukulawulwa kokugeleza kwamanzi.
- 4).Uhlelo lwe-oyela kaphethiloli oludinga ukuqina kokuvuza.
- 5).Izinhlelo zokulawula i-valve bypass.
- 6).Imigodi yokungenisa umoya ephezulu kanye nemisele yamanzi ephansi.
- 7).Uwoyela negesi, Amanzi okungenisa, ukudla kwamakhemikhali, i-Refinery, ukukhishwa komoya we-condenser, kanye nezinhlelo zokukhipha amanzi.
- 8).Amapayipi okungenisa umoya namapayipi okuhambisa umoya ebhoyila, izinsizakalo zomusi, amapayipi okungenisa umoya namapayipi okuhambisa umoya amakhulu, kanye namapayipi okuhambisa umoya e-heater.
- 9).I-turbine ivala futhi ikhiphe amanzi.
