Ikhwalithi Ephakeme Ye-API Ejwayelekile Yomhlaba Wonke Ye-Global Globe Valve Ifektri yaseShayina
Iyini i-valve ye-API globe?
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 yomhlaba wonke ye-API ingenye 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 wezihlaloI-valve yomhlaba wonke ye-APIingalawulwa kahle ngesiqu esinesikulufo. Amandla okuvala
I-valve yomhlaba wonke ye-APIkuphezulu kakhulu. Zingasetshenziswa emsebenzini wokuvala. Ngenxa yebanga elifushane lokuhamba kwediski phakathi kwezindawo ezivulekile nezivaliwe,I-valve yomhlaba wonke ye-APIzilungele uma ivalvu kufanele ivulwe futhi ivalwe njalo. Ngakho-ke, amavalvu agcwele angasetshenziswa emisebenzini eyahlukahlukene.
Isici esiyinhloko se-valve yomhlaba wonke ye-API
- 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.

Imikhiqizo ikhombisa: i-API globe valve
Ukusetshenziswa kwe-valve ye-API globe
I-valve yomhlaba wonke ye-API isetshenziswa 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.
