I-ASME Globe Valve
Yini i-ASME Globe Valve?
Ama-valve eglobhu angama-valve avalayo ahambayo ahambayo asetshenziselwa ukuqala, ukumisa noma ukulawula ukugeleza kusetshenziswa ilungu lokuvala elibizwa ngokuthi idiski.Isihlalo se-valve ye-globe siphakathi nendawo futhi sihambisana nepayipi, futhi ukuvuleka kwesihlalo kuvaliwe nge-disc noma ipulaki.I-disc ye-globe valve ingavala ngokuphelele indlela yokugeleza noma ingasuswa ngokuphelele.Ukuvuleka kwesihlalo kushintsha ngokulingana nokuhamba kwediski okulungele imisebenzi ehlanganisa ukulawulwa kokugeleza.Ama-valve eglobhu afaneleka kakhulu futhi asetshenziswa kabanzi ukulawula noma ukumisa ukugeleza koketshezi noma igesi ngepayipi ukuze liphuqe futhi lilawule ukugeleza koketshezi futhi ngokuvamile asetshenziswa kumapayipi kasayizi omncane.
I-ASME Globe valveingenye 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 weAma-valve embulunga ye-ASMEingalawulwa kahle ngesiqu esisikwe.Umthamo wokuvala weI-valve yomhlaba ye-ASMEiphezulu kakhulu.Angasetshenziselwa umsebenzi ongekho emsebenzini.Ngenxa yebanga elifushane lokuhamba lediski phakathi kwezindawo ezivuliwe nezivaliwe,Ama-valve embulunga ye-ASMEzilungile uma i-valve kufanele ivulwe futhi ivalwe njalo.Ngakho-ke, ama-valve embulunga angasetshenziselwa imisebenzi eminingi.
iAma-valve we-ASME Globeingase 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, kunamaphethini 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
- 3).Iphethini e-Oblique (eyaziwa nangokuthi Iphethini ye-Wye noma i-Y - Pattern)
Umgomo Wokusebenza weI-ASME Globe Valve
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 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 yeglobu 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, ngezinjongo ezihlukahlukene.
- 6).Ikhono elimaphakathi ukuya kokuhle lokudonsa, ngokulungisa ukwakheka kwesihlalo nediski.
- 7).Bi-ellows seal iyatholakala uma uyicela.

- 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.
- 8).Izimbobo zamabhoyili namadrayini, Izinkonzo ze-Steam, izimbobo zomusi ezinkulu namadrayini, namapayipi okufudumeza.
