Umgangatho oPhezulu woShishino API602 umzi-mveliso we-Stop Steel Stop Globe waseTshayina
Yintoni ivalve yeglowubhu ye-API602?
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.
iAPI602 Globe iValveingasetyenziselwa 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 weAPI602 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 kwivalve yeglowubhu ye-API602
- 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).Imodareyitha ukuya kokulungileyo ukugoba amandla, ngokuguqula ubume besihlalo kunye nediski.
- 4).Bi-ellows seal iyafumaneka xa uyicela.
