Umgangatho oPhezulu woShishino lweWholeliseli oPhakamileyo onemisonto yeGlobe iValve yoMzi mveliso waseTshayina
Yintoni i-Threaded 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 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 yeGlobe enemisontololona 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 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.
iIvalve yeGlobe enemisontoingasetyenziselwa iinjongo zokugobhoza ngokunjalo.Iibhodi ezininzi zevalvu ehleli enye zisebenzisa ikheji okanye ulwakhiwo lwesigcini sokugcina ukugcina isangqa, ukubonelela ngesikhokhelo seplagi yevalvu, 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)
Eyona nto iphambili yeThreaded 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;
- 6).Imodareyitha ukuya kokulungileyo ukugoba amandla, ngokuguqula ubume besihlalo kunye nediski.
- 7).Bi-ellows seal iyafumaneka xa uyicela.

Ukusetyenziswa kwe-Threaded Globe Valve
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 ye-oyile ye-fuel efuna ukuvuza kokuqina.
- 5).Iinkqubo zokudlula ivalve yokulawula.
- 6).Iindawo zokungenisa umoya eziphakamileyo kunye neendawo ezisezantsi zokukhupha amanzi.
