Yintoni i-ASME 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 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.
Ivalve yeGlobhu ye-ASME Ubungakanani obukhulu beGlobe iValvelolona yilo ludumileyo lweevalvu zeglowubhu, ze-US kunye ne-API system.the ubukhulu bangaphakathi, izixhobo, ubuso ngobuso, udonga olungqingqwa, ubushushu boxinzelelo, zichazwa yi-ASME B16.34.
Ukongeza, kuxhomekeke kuyilo lwesihlalo kunye nediski, umthwalo wokuhlala weUbungakanani obukhulu beGlobe Valveinokulawulwa kakuhle ngesiqu esikrufu.Umthamo wokutywina wobungakanani obukhulu beGlobe Valve uphezulu kakhulu.Zingasetyenziselwa ukungabikho emsebenzini.Ngenxa yohambo olufutshane lwediski phakathi kweendawo ezivulekileyo nezivaliweyo, iValve yeGlobe yeGlobe ilungile ukuba ivalve kufuneka ivulwe kwaye ivalwe rhoqo.Ke, iivalvu zeglowubhu zinokusetyenziselwa uluhlu olubanzi lwemisebenzi.
Ivalve yeglobhu yesayizi enkulu ingasetyenziselwa iinjongo zokugobhoza ngokunjalo.Iibhodi ezininzi ezihleli umntu omnye zisebenzisa ikheji okanye ulwakhiwo lwesigcini sokugcina ukugcina isangqa, ukubonelela ngesikhokelo seplagi yevalve, kunye nokubonelela ngeendlela zokuseka iimpawu ezithile zokuhamba kwevalvu.Isenokuguqulwa ngokulula ngotshintsho lweziqendu zetrim ukutshintsha uphawu lokuhamba okanye ukunika umthamo oncitshisiweyoukuhamba, ukunciphisa ingxolo, okanye ukunciphisa okanye ukupheliswa kwe-cavitation.
Uphawu oluphambili lwe-ASME Globe valve Ubungakanani obukhulu beGlobe 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.
- 5).Easy Machining kunye nokuphinda kuvele izihlalo, ngeenjongo ezahlukeneyo.
