Umgangatho oPhezulu woShishino we-SDNR weglowubhu ivalvu yeglowubhu yaseTshayina umnikezeli wefektri yoMvelisi
Yintoni ivalve yeglowubhu ye-SDNR?
Ivalve yeglowubhu ye-SDNRiyilwe 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 yeglowubhu ye-SDNRingasetyenziselwa 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 lweIvalve yeglowubhu ye-SDNR:
- 1).Ipateni eMiselweyo (kunye nePateni yeTee okanye iT – Ipateni okanye uZ – Ipateni)
- 2).Ipateni ye-Oblique (ekwaziwa ngokuba yi-Wye Pattern okanye i-Y-Pateni)
Iimpawu eziphambili zevalve yeglowubhu ye-SDNR?
Ipateni eqhelekileyo(ipateni ethe tye)
Ipateni ye-engile
Ipateni eqhelekileyo ene-bellows seal
- 1) Umgama omfutshane wokuhamba wediski (stroke) phakathi kweendawo ezivulekileyo nezivaliweyo,I-DIN-EN iivalvu zeglowubhuzifanelekile 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).
- 5) .Easy Machining kunye resurfacing izihlalo, ngeenjongo ezahlukeneyo.
- I-6) .Imodareyitha ukuya kwi-throttling elungileyo, ngokuguqula isakhiwo sesihlalo kunye nediski.
- 7) Isetyenziswa kakhulu kuwo onke amazwe akumanyano lwaseYurophu, nakwamanye amazwe ngokunjalo.
- 8).Bellows seal iyafumaneka ngesicelo.
Ukulawula uyilo lwediski
Uyilo lwediski yokulinganisa, i-DN200 nangaphezulu
