Umgangatho oPhezulu woShishino oluPhezulu lweFlanged Glove iValve yoMzimveliso waseTshayina
Yintoni iValufa yeGlavu eFlanged?
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 i-Flanged Glove valvelolona 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 weFlanged Glove Valve unokulawulwa ngokufanelekileyo ngesiqu esikrufu.Umthamo wokutywina weFlanged Glove Valve uphezulu kakhulu.Zingasetyenziselwa ukungabikho emsebenzini.Ngenxa yohambo olufutshane lwediski phakathi kweendawo ezivulekileyo nezivaliweyo, i-valve ye-Flanged Glove ifanelekile ukuba i-valve kufuneka ivulwe kwaye ivalwe rhoqo.Ke, iivalvu zeglowubhu zinokusetyenziselwa uluhlu olubanzi lwemisebenzi.
Ivalve yeglove eneFlanged ingasetyenziselwa iinjongo zokuthontsiza ngokunjalo.Amaqela amaninzi ahlala umntu omnye asebenzisa ikheyiji okanye ulwakhiwo lwendlela yogcino ukugcina isangqa, ukubonelela ngesikhokelo seplagi yevalve, 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)
Uphawu oluphambili lwe-Flanged Glove 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.
