I-Wholesale Industrial Large size Globe Valve Umthengisi wefektri waseTshayina Umvelisi
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-ASME enkulu Ivalvu yeGlobe enkuluyenye 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.
Ukongeza, kuxhomekeke kuyilo lwesihlalo kunye nediski, umthwalo wezihlaloIvalvu yeGlobe enkulu yobukhulu obukhuluinokulawulwa kakuhle ngesiqu esikrufulwe nge-screw. Umthamo wokuvala we-Large size Globe Valve uphezulu kakhulu. Zingasetyenziselwa umsebenzi wokuvala. Ngenxa yomgama omfutshane wokuhamba wediski phakathi kweendawo ezivulekileyo nezivaliweyo, i-Large size Globe Valve ifanelekile ukuba i-valve kufuneka ivulwe kwaye ivalwe rhoqo. Ke ngoko, ii-globe valves zingasetyenziselwa imisebenzi eyahlukeneyo.
I-Large size Globe Valve ingasetyenziselwa neenjongo zokuqhobosha. Iivalvu ezininzi ezihlala umntu omnye zisebenzisa ulwakhiwo lwekheji okanye uhlobo lwe-retainer ukugcina iringi yesihlalo, ukubonelela ngesikhokelo seplagi yevalvu, kunye nokubonelela ngeendlela zokuseka iimpawu ezithile zokuhamba kwevalvu. Ingatshintshwa ngokulula ngokutshintsha iindawo zokusika ukutshintsha uphawu lokuhamba okanye ukubonelela ngomthamo ophantsi.ukuhamba, ukunciphisa ingxolo, okanye ukunciphisa okanye ukuphelisa i-cavitation.
Eyona nto iphambili kwi-ASME Globe valve
- 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.
- 4).TNazi iindlela ezahlukeneyo zobuchule ezifumanekayo kwiindlela ze-tee, Wye, kunye ne-angle body.
- 5).Ukuyilungisa nokuyifaka kwakhona izihlalo ngokulula, ngeenjongo ezahlukeneyo.
