Umgangatho oPhakamileyo weWholeliseli yoShishino oSingle uhleli kwiGlobe iValve yoMzi mveliso waseTshayina
Yintoni iValve yeglowubhu ehleliyo eNye?
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.
Ivalufa yeGlobe ehleliyo enye yenye yolona yilo ludumileyo lweevalvu zeglowubhu, ze-US kunye ne-API system.the diameter yangaphakathi, izixhobo, ubuso ngobuso, ubukhulu bodonga, ubushushu boxinzelelo, zichazwa yi-ASME B16.34.
Ukongeza, kuxhomekeke kuyilo lwesihlalo kunye nediski, umthwalo wokuhlala we-Single Seated Globe Valve unokulawulwa ngokufanelekileyo ngesiqu esikrufu.Umthamo wokutywina we-Single Seated Globe Valve uphezulu kakhulu.Zingasetyenziselwa ukungabikho emsebenzini.Ngenxa yohambo olufutshane lwediski phakathi kweendawo ezivulekileyo nezivaliweyo, i-Single Seated Globe Valve ifanelekile ukuba ivalve kufuneka ivulwe kwaye ivalwe rhoqo.Ke, iivalvu zeglowubhu zinokusetyenziselwa uluhlu olubanzi lwemisebenzi.
Ivalve yeglowubhu ehleliyo eNye ingasetyenziselwa iinjongo zokuthontsiza ngokunjalo. Uninzi lwezigqeba ezihleli umntu omnye zisebenzisa ikheji okanye ulwakhiwo lwesigcini sokugcina ukugcina isangqa, ukubonelela ngesikhokhelo seplagi yevalvu, kunye nokubonelela ngeendlela zokuseka iimpawu ezithile zokuqukuqela kwevalvu.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)
Inqaku eliphambili le-Single Seated 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.

Iimveliso zibonisa: IValve yeGlobe yeSingle Seated
Ukusetyenziswa kweValve yeGlobe ehleliyo eNye
ASME Globe iValveisetyenziswa 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.
- 5).Iinkqubo zokudlula ivalve yokulawula.
