I-valve yeglobe yeGlobe yoMbane oPhezulu oPhezulu oMgangatho oPhezulu Umvelisi wefektri yaseTshayina
Yintoni i-ASME Globe Valve?
Iivalvu zeglobe ziivalvu zokuvala ezihamba ngomgca ezisetyenziselwa ukuqala, ukumisa okanye ukulawula ukuhamba kusetyenziswa ilungu lokuvala elibizwa ngokuba yidiski. Isihlalo sevalvu yeglobe siphakathi kwaye sihambelana nombhobho, kwaye ukuvulwa kwesihlalo kuvalwa ngediski okanye iplagi. Idiski yevalvu yeglobe ingavala ngokupheleleyo indlela yokuhamba okanye ingasuswa ngokupheleleyo. Ukuvulwa kwesihlalo kutshintsha ngokulinganayo ngokuhamba kwediski, nto leyo efanelekileyo kwimisebenzi ebandakanya ukulawulwa kokuhamba. Iivalvu zeglobe zifanelekile kwaye zisetyenziswa kakhulu ukulawula okanye ukumisa ukuhamba kolwelo okanye igesi kumbhobho ukuze kuthintelwe kwaye kulawulwe ukuhamba kolwelo kwaye zihlala zisetyenziswa kwiipayipi ezincinci.
Ivalvu yeGlobe ye-ASMEyenye yezona ndlela zidumileyo zoyilo lweevalvu zeglobe, zenkqubo ye-US kunye ne-API. Ububanzi bangaphakathi, izixhobo, ubuso ngobuso, ubukhulu bodonga, ubushushu boxinzelelo, zichazwa yi-ASME B16.34.
Eyona nto iphambili kwivalvu yeglobhu yoxinzelelo oluphezulu
- 1) .Izakhono ezilungileyo zokutywina
- 2). Umgama omfutshane wokuhamba kwediski (stroke) phakathi kweendawo ezivulekileyo nezivaliweyo,Iivalvu zeglobhu ze-ASMEzilungele ukuba ivalvu kufuneka ivulwe kwaye ivalwe rhoqo;
- 3).Ivalvu yeglobhu ye-ASME ingasetyenziswa njengevalvu yokujonga ukumisa ngokutshintsha uyilo kancinci.

Iimveliso zibonisa ivalvu yeglobhu yoxinzelelo oluphezulu
Ukusetyenziswa kwevalvu yeglobhu yoxinzelelo oluphezulu
Ivalvu yeGlobe ye-ASME Ivalvu yeGlobe yoxinzelelo oluphezuluIsetyenziswa kakhulu kwiinkonzo ezahlukeneyo; zombini iinkonzo zoxinzelelo oluphantsi kunye nolwelo oluphezulu. Iindlela eziqhelekileyo zokusetyenziswa kweevalvu zeglobe zezi:
- 1). Yenzelwe imibhobho ekhutshwa rhoqo, okanye ukuthomalalisa ulwelo kunye negesi ephakathi
- 2). Ulwelo: Amanzi, umphunga, umoya, ipetroliyam ekrwada kunye neemveliso zepetroliyam, igesi yendalo, igesi econdensate, izisombululo zobuchwepheshe, ioksijini, iigesi ezingamanzi nezingenalo ugonyamelo
- 3).Iinkqubo zamanzi okupholisa ezifuna ukulawulwa kokuhamba kwamanzi.
- 4).Inkqubo yeoyile yepetroli efuna ukuvaleka.
