Umgangatho oPhakamileyo weGlobu yezoShishino jonga ivalve yaseTshayina umnikezeli wefektri uMvelisi
Yintoni ivalve yokujonga iGlobe?
Ivalve yokujonga iglowubhu iyilwe kwaye yenziwa ngokomgangatho wangaphambili waseJamani, iDIN kwaye namhlanje umgangatho waseYurophu EN13709.isetyenziswa kakhulu kumazwe akwiManyano yaseYurophu.
Ivalve yentshukumo evalayo isetyenziselwa ukuqalisa, ukumisa okanye ukulawula ukuhamba kusetyenziswa ilungu lokuvala elibizwa ngokuba yidiski.Ukuvulwa kwesitulo kutshintsha ngokulinganayo kunye nokuhamba kwediski efanelekileyo kwimisebenzi ebandakanya ukulawulwa kokuhamba.iivalve ze-DIN-EN Globe zezona zifanelekileyo kwaye zisetyenziswa ngokubanzi ukulawula okanye ukumisa ukuhamba kolwelo okanye irhasi ngombhobho wokungqusha kunye nokulawula ukuhamba kolwelo kwaye zisetyenziswa ngokubanzi kwimibhobho yobungakanani obuncinci.
iIvalve yokujonga iglowubhuingasetyenziselwa iinjongo zokugobhoza ngokunjalo.Iibhodi ezininzi ezihleli phantsi kweevalvu zisebenzisa ikheyiji okanye ulwakhiwo lwesigcini sokugcina ukugcina isangqa, ukubonelela ngesikhokelo seplagi yevalve, kunye nokubonelela ngeendlela zokuseka iimpawu zokuqukuqela kwevalve ethile.iyakwazi ukuguqulwa ngokulula ngokutshintshwa kweengxenye ze-trim ukuguqula uphawu lokuhamba okanye ukubonelela ukuhamba okuncitshisiweyo komthamo, ukunciphisa ingxolo, okanye ukunciphisa okanye ukupheliswa kwe-cavitation.
ngokwesiqhelo kukho iipateni ezingundoqo ezintathu zomzimba okanye uyilo lwe Ivalve yokujonga iglowubhu:
- 1).Ipateni eMiselweyo (kunye nePateni yeTee okanye iT – Ipateni okanye uZ – Ipateni)
- 2).Ipateni ye-engile
- 3).Ipateni ye-Oblique (ekwaziwa ngokuba yi-Wye Pattern okanye i-Y-Pateni)
Iimpawu eziphambili zeGlobe check valve
Ipateni eqhelekileyo(ipateni ethe tye)
Ipateni ye-engile
Ipateni eqhelekileyo ene-bellows seal
- 1) Umgama omfutshane wokuhamba wediski (stroke) phakathi kweendawo ezivulekileyo nezivaliweyo,Ivalve yokujonga iglowubhuzifanelekile ukuba ivalve kufuneka ivulwe kwaye ivalwe rhoqo;
- 2).Izakhono zokutywina ezilungileyo
- 3) .Kukho uluhlu olubanzi lwezakhono njengoko lufumaneka kwipatheni eqhelekileyo (ipateni yokolula), ipateni ye-Angle, kunye nepateni ye-Wye (ipateni ye-Y).
- 4) .Ivalve yeglowubhu ye-DIN-EN ingasetyenziswa njengevalve ye-SDNR,ivalve yokujonga iglowubhu ngokuguqula uyilo kancinane.
- 5) .Easy Machining kunye resurfacing izihlalo, ngeenjongo ezahlukeneyo.
- I-6) .Imodareyitha ukuya kwi-throttling elungileyo, ngokuguqula isakhiwo sesihlalo kunye nediski.
Ukulawula uyilo lwediski
Uyilo lwediski yokulinganisa, i-DN200 nangaphezulu
