ASME Globe iValve
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.
Ukongeza, kuxhomekeke kuyilo lwesihlalo kunye nediski, umthwalo wokuhlala weIivalvu zeglowubhu ze-ASMEinokulawulwa kakuhle ngesiqu esikrufu.Umthamo wokutywina weIvalve yeglowubhu ye-ASMEiphezulu kakhulu.Zingasetyenziselwa ukungabikho emsebenzini.Ngenxa yomgama omfutshane wokuhamba wediski phakathi kweendawo ezivulekileyo nezivaliweyo,Iivalvu zeglowubhu ze-ASMEzifanelekile ukuba ivalve kufuneka ivulwe kwaye ivalwe rhoqo.Ke, iivalvu zeglowubhu zinokusetyenziselwa uluhlu olubanzi lwemisebenzi.
iIivalvu ze-ASME Globeingasetyenziselwa iinjongo zokugobhoza ngokunjalo.Iibhodi ezininzi ezihleli phantsi kweevalvu zisebenzisa ikheyiji okanye ulwakhiwo lwesigcini sokugcina ukugcina isangqa, ukubonelela ngesikhokelo seplagi yevalve, kunye nokubonelela ngeendlela zokuseka iimpawu zokuqukuqela kwevalve ethile.Isenokuguqulwa ngokulula ngotshintsho lweziqendu zetrim ukutshintsha uphawu lokuhamba okanye ukunika umthamo oncitshisiweyoukuhamba, ukunciphisa ingxolo, okanye ukunciphisa okanye ukupheliswa kwe-cavitation.
Iipateni zoMzimba we-ASME Globe, kukho iipateni ezintathu eziphambili zomzimba okanye uyilo lweevalvu zeGlobe, ezizezi:
- 1).Ipateni eMiselweyo (ekwabizwa ngokuba yiPateni yeTee okanye iT – Ipateni okanye uZ – Ipateni)
- 2).Ipateni ye-engile
- 3).Ipateni ye-Oblique (ekwaziwa ngokuba yi-Wye Pattern okanye i-Y-Pateni)
Umgaqo wokuSebenza weASME Globe iValve
Ivalve yeglowubhu yenziwe ngediski eshukumayo kunye nesitulo seringi esimileyo kumzimba ongqukuva.Isihlalo sevalve yeglowubhu siphakathi kwaye sihambelana nombhobho, kwaye ukuvulwa kwesitulo kuvaliwe ngediski.xa i-handwheel ijikelezwa ngesandla okanye nge-actuator, i-disc movement ilawulwa (iyancipha okanye iphakanyiswe) ngokusebenzisa i-valve stem.Xa idiskhi yeglowubhu yeglowubhu ihleli phezu kweringi yesitulo, ukuhamba kuyekiswa ngokupheleleyo.
Eyona nto iphambili ye-ASME Globe valve
- 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.
- 4).Tnalu uluhlu olubanzi lwezakhono njengoko lufumaneka kwitee, iWye, kunye nezimbo zomzimba ze-engile.
- 5).Easy Machining kunye nokuphinda kuvele izihlalo, ngeenjongo ezahlukeneyo.
- 6).Imodareyitha ukuya kokulungileyo ukugoba amandla, ngokuguqula ubume besihlalo kunye nediski.
- 7).Bi-ellows seal iyafumaneka xa uyicela.
