Umgangatho oPhakamileyo weWholeliseli oPhezulu woxinzelelo lweglowubhu ivalve yeglowubhu iValve yaseTshayina umniki-mveliso
Yintoni i-ASME Globe Valve?
Iivalvu zeglowubhu ziivalve ezivalayo eziya mva ezisetyenziselwa ukuqala, ukumisa okanye ukulawula ukuhamba kusetyenziswa ilungu lokuvala elibizwa ngokuba yidiski.Isihlalo sevalve yeglowubhu siphakathi kwaye sihambelana nombhobho, kwaye ukuvuleka kwesitulo kuvaliwe nge-disc okanye iplagi.I-disc yevalve yeglowubhu inokuvala ngokupheleleyo indlela yokuhamba okanye inokususwa ngokupheleleyo.Ukuvulwa kwesitulo kutshintsha ngokulinganayo kunye nokuhamba kwediski efanelekileyo kwimisebenzi ebandakanya ukulawulwa kokuhamba.Iivalvu zeglowubhu zezona zifanelekileyo kwaye zisetyenziswa ngokubanzi ukulawula okanye ukumisa ukuhamba kolwelo okanye irhasi ngombhobho wokungqusha nokulawula ukuhamba kolwelo kwaye zisetyenziswa ngokubanzi kwimibhobho yobungakanani obuncinci.
Ivalve yeGlobhu ye-ASMElolona yilo ludumileyo lweevalvu zeglowubhu, ze-US kunye ne-API system.the ubukhulu bangaphakathi, izixhobo, ubuso ngobuso, udonga olungqingqwa, ubushushu boxinzelelo, zichazwa yi-ASME B16.34.
Eyona nto iphambili yevalve yeglowubhu yoxinzelelo oluPhezulu
- 1).Izakhono zokutywina ezilungileyo
- 2) Umgama omfutshane wokuhamba wediski (stroke) phakathi kweendawo ezivulekileyo nezivaliweyo,Iivalvu zeglowubhu ze-ASMEzifanelekile ukuba ivalve kufuneka ivulwe kwaye ivalwe rhoqo;
- 3).Ivalve yeglowubhu ye-ASME ingasetyenziswa njengevalve yokumisa ngokuguqula uyilo kancinane.

Iimveliso zibonisa ivalve yeglowubhu yoxinzelelo oluPhezulu
Ukusetyenziswa kwevalve yeglowubhu yoxinzelelo oluPhezulu
Ivalve yeglowubhu ye-ASME yeGlobe ePhakamileyoisetyenziswa ngokubanzi kuluhlu olubanzi lweenkonzo;zombini uxinzelelo oluphantsi kunye neenkonzo zoxinzelelo oluphezulu lwamanzi.Usetyenziso oluqhelekileyo lweevalvu zeglowubhu zezi:
- 1).Yenzelwe umbhobho ophuma rhoqo, okanye ukucinezela ulwelo kunye nesiphakathi segesi
- 2) Ulwelo: Amanzi, umphunga, umoya, i-petroleum ekrwada kunye neemveliso zepetroleum, irhasi yendalo, i-gas condensate, izisombululo zetekhnoloji, ioksijini, ulwelo kunye neegesi ezingezizo.
- 3).Iinkqubo zokupholisa zamanzi ezifuna ukulawulwa kokuhamba.
- 4).Inkqubo yeoli ye-fuel ifuna ukuvuza kokuqina.
