Umgangatho oPhezulu waMazwe ngaMazwe we-API weGlobe Valve umzi-mveliso waseTshayina
Yintoni i-API valve yeglowubhu?
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 ngediski 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 yeglowubhu ye-API lolona yilo ludumileyo lweevalvu zeglowubhu, ze-US kunye ne-API system.the ngaphakathi ubukhulu, izixhobo, ubuso ngobuso, ubukhulu bodonga, ubushushu boxinzelelo, zichazwa yi-ASME B16.34.
Ukongeza, kuxhomekeke kuyilo lwesihlalo kunye nediski, umthwalo wokuhlala weIvalve yeglowubhu ye-APIinokulawulwa kakuhle ngesiqu esikrufu.Umthamo wokutywina we
Ivalve yeglowubhu ye-APIiphezulu kakhulu.Zingasetyenziselwa ukungabikho emsebenzini.Ngenxa yomgama omfutshane wokuhamba wediski phakathi kweendawo ezivulekileyo nezivaliweyo,Ivalve yeglowubhu ye-APIzifanelekile ukuba ivalve kufuneka ivulwe kwaye ivalwe rhoqo.Ke, iivalvu zeglowubhu zinokusetyenziselwa uluhlu olubanzi lwemisebenzi.
Uphawu oluphambili lwevalve yeglowubhu ye-API
- 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.

Iimveliso zibonisa: Ivalve yeglowubhu ye-API
Ukusetyenziswa kwevalve yeglowubhu ye-API
Ivalve yeglowubhu ye-API isetyenziswa 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 ye-oyile ye-fuel efuna ukuvuza kokuqina.
- 5).Iinkqubo zokudlula ivalve yokulawula.
