Ikhwalithi ephezulu Yezimboni ASME B16.34 ivalvu yeglobhu yaseChina ifektri
Yini i-ASME B16.34 valvu yeglobhu?
I-ASME B16.34 ivalvu yeglobhuingenye yemiklamo edume kakhulu yamavalvu embulunga, ye-US kanye nesistimu ye-API.ububanzi bangaphakathi, izinto, ubuso nobuso, ukujiya kodonga, izinga lokushisa lokucindezela, kuchazwa yi-ASME B16.34.
Ngaphezu kwalokho, kuye ngomklamo wesihlalo nediski, umthwalo wokuhlala weI-ASME B16.34 ivalvu yeglobhuingalawulwa kahle ngesiqu esisikwe.
iI-ASME B16.34 ivalvu yeglobhuingase isetshenziselwe izinjongo zokudonsa futhi.Izindikimba zamavalvu eziningi ezihlezi ngabodwa zisebenzisa ikheji noma ukwakhiwa kwesitayela sokugcina ukugcina indandatho yesihlalo, zinikeze umhlahlandlela wamapulaki e-valve, futhi zinikeze izindlela zokusungula izici ezithile zokugeleza kwamavalvu.ingase futhi ilungiswe kalula ngokushintsha izingxenye zokunquma ukushintsha isici sokugeleza noma ukunikeza umthamo oncishisiweukugeleza, ukunciphisa umsindo, noma ukunciphisa noma ukuqedwa kwe-cavitation.
I-ASME Globe Valve Body Patterns, kukhona amaphethini omzimba amathathu ayinhloko noma imiklamo yama-valve e-Globe, okungukuthi:
- 1).Iphethini Ejwayelekile (eyaziwa nangokuthi Iphethini yeTee noma i-T - Iphethini noma i-Z - Iphethini)
- 2).Iphethini ye-engeli
Isimiso Sokusebenza oI-ASME B16.34 ivalvu yeglobhu
Ivalvu yeglobhu yakhiwe ngediski egudlukayo kanye nesihlalo esiyindandatho esimile emzimbeni oyindilinga.Isihlalo se-valve ye-globe siphakathi nendawo futhi sihambisana nepayipi, futhi indawo yokuhlala ivaliwe nge-disc.lapho isondo lesandla lijikeleziswa ngesandla noma nge-actuator, ukunyakaza kwe-disc kulawulwa (kwehlisiwe noma kuphakanyiswe) ngokusebenzisa i-valve stem.Lapho i-globe valve disc ihlezi phezu kweringi yesihlalo, ukugeleza kumiswe ngokuphelele.
Isici esiyinhloko se-ASME B16.34 globe valve
- 1)Amakhono amahle okuvala uphawu
- 2).Ibanga elifushane lokuhamba lediski(stroke) phakathi kwezindawo ezivuliwe nezivaliwe,Ama-valve embulunga ye-ASMEzilungile uma i-valve kufanele ivulwe futhi ivalwe njalo;
- 3).I-valve yeglobhu ye-ASME ingasetshenziswa njenge-valve yokuhlola ukumisa ngokulungisa umklamo kancane.
- 4).Tnansi izinhlobonhlobo zamakhono njengoba etholakala ku-tee, i-Wye, nezitayela zomzimba ze-engeli.
- 5).Easy Machining kanye kabusha izihlalo, ngezinhloso ezahlukene.

Ukusetshenziswa kwevalvu yeglobhu ye-ASME B16.34
I-ASME Globe Valveisetshenziswa kabanzi ezinhlobonhlobo zezinsizakalo;kokubili ukucindezela okuphansi kanye nezinsizakalo zoketshezi ezinomfutho ophezulu.Izindlela ezijwayelekile zokusebenzisa ama-valve eglobe yilezi:
- 1).Idizayinelwe ipayipi elivalekile elivalekile, noma ukumpintsha uketshezi negesi
- 2).Uketshezi:Amanzi, isitimu, umoya, uphethiloli ongahluziwe kanye nemikhiqizo kaphethiloli, igesi yemvelo, i-gas condensate, izixazululo zobuchwepheshe, umoya-mpilo, umoya-mpilo, uketshezi kanye namagesi angewona anamandla.
- 3).Amasistimu amanzi okupholisa adinga ukulawulwa kokugeleza.
- 4).Isistimu kawoyela kawoyela edinga ukucisha ukuvuza.
- 5).Amasistimu wokudlula ama-valve.
- 6).Ama-vents aphezulu kanye nama-drain-point-drain.
- 7).Uwoyela Negesi, Amanzi Okuphakelayo, okuphakelayo kwamakhemikhali, Indawo yokucwenga, ukukhipha umoya we-condenser, namasistimu wokudonsa amanzi.
