Umgangatho ophezulu woShishino lwe-DIN-EN Umzi-mveliso weglobhu weglowubhu waseTshayina
Yintoni ivalve yeglowubhu?
Ivalve yeglowubhuiyilwe 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.
iIivalvu zeglobhuingasetyenziselwa 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 lweIivalvu zeglobhu:
- 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 zevalve yeglowubhu?
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).
- 4) .Ivalve yeglowubhu ye-DIN-EN ingasetyenziswa njengevalve ye-SDNR,ivalve yokujonga iglowubhu ngokuguqula uyilo kancinane.
- 5) .Easy Machining kunye resurfacing izihlalo, ngeenjongo ezahlukeneyo.
Ukulawula uyilo lwediski
Uyilo lwediski yokulinganisa, i-DN200 nangaphezulu

uMboniso weMveliso:
Ukusetyenziswa kweevalvu zeglowubhu
Ivalve yeglowubhu isetyenziswa ngokubanzi kwiuluhlu olubanzi lweenkonzo, zombini uxinzelelo oluphantsi kunye neenkonzo zoxinzelelo oluphezulu lwamanzi.
- 1) Ulwelo:Amanzi, umphunga, umoya, i-petroleum ekrwada kunye neemveliso zepetroleum, irhasi yendalo, i-gas condensate, izisombululo zetekhnoloji, ioksijini, ulwelo kunye neegesi ezingezizo.
- 2) .Iinkqubo zokupholisa zamanzi ezifuna ukubekwa zodwa kunye nokulawulwa kokuhamba.
- 3) .Iindawo eziphakamileyo eziphezulu kunye neendawo ezisezantsi.
- I-4) .Ii-boiler vents kunye ne-drain, Iinkonzo ze-Steam, ii-stents eziphambili kunye ne-drain, kunye ne-heater drains.
