Imboni yekhwalithi ephezulu ye-DIN-EN Globe valve yaseChina
Yini i-globe valve?
I-valve yomhlabayakhelwe futhi yakhiqizwa ngokwezinga langaphambili laseJalimane, i-DIN futhi namuhla indinganiso yaseYurophu EN13709.isetshenziswa kakhulu emazweni ase-European Union.
iyivalve evalayo evalayo enyakazayo esetshenziselwa ukuqala, ukumisa noma ukulawula ukugeleza kusetshenziswa ilungu lokuvala elibizwa ngokuthi idiski.Ukuvuleka kwesihlalo kushintsha ngokulingana nokuhamba kwediski okulungele imisebenzi ehlanganisa ukulawulwa kokugeleza.ama-valve e-DIN-EN Globe afaneleka kakhulu futhi asetshenziswa kabanzi ukulawula noma ukumisa ukugeleza koketshezi noma igesi ngepayipi ukuze kushaye futhi kulawule ukugeleza koketshezi futhi ngokuvamile asetshenziswa kumapayipi osayizi abancane.
iAma-valve e-globeingase isetshenziselwe izinjongo zokudonsa futhi.Izindikimba zamavalvu eziningi ezihlezi zisebenzisa ikheji noma ukwakhiwa kwesitayela sokugcina ukugcina indandatho yesihlalo, zinikeze umhlahlandlela wamapulaki e-valve, futhi zinikeze izindlela zokusungula izici ezithile zokugeleza kwamavalvu.ingabuye ishintshwe kalula ngokushintshwa kwezingxenye zokunquma ukushintsha isici sokugeleza noma inikeze ukugeleza kwekhono elincishisiwe, ukuncishiswa komsindo, noma ukunciphisa noma ukuqedwa kwe-cavitation.
ngokuvamile kunamaphethini amathathu okuqala omzimba noma imiklamoAma-valve e-globe:
- 1).Iphethini Ejwayelekile (futhi njengephethini yeTee noma i-T - Iphethini noma i-Z - Iphethini)
- 2).Iphethini ye-engeli
- 3).Iphethini e-Oblique (eyaziwa nangokuthi Iphethini ye-Wye noma i-Y - Pattern)
Izici eziyinhloko ze-globe valve?
Iphethini ejwayelekile(iphethini eqondile)
Iphethini ye-engeli
Iphethini evamile ene-bellows seal
- 1).Ibanga elifushane lokuhamba lediski(stroke) phakathi kwezindawo ezivuliwe nezivaliwe,I-DIN-EN amavalvu eglobhuzilungile uma i-valve kufanele ivulwe futhi ivalwe njalo;
- 2).Amakhono amahle okuvala uphawu
- 3).Kunobubanzi obuhlukahlukene bamakhono njengoba butholakala kuphethini evamile(iphethini yokuqina), iphethini ye-engeli, kanye nephethini ye-Wye(iphethini engu-Y).
- 4).Ivalvu yeglobhu ye-DIN-EN ingasetshenziswa njengevalvu ye-SDNR,ivalve yokuhlola imbulunga ngokushintsha umklamo kancane.
- 5).Ukushicilela okulula nokufaka kabusha izihlalo, ngezinhloso ezahlukahlukene.
Ukulawula ukwakheka kwediski
Idizayini yokulinganisa idiski, i-DN200 nangaphezulu

Umbukiso Womkhiqizo:
Ukusetshenziswa kwama-valve embulunga
I-Globe Valve isetshenziswa kabanzi kuinhlobonhlobo yezinsizakalo, zombili ingcindezi ephansi kanye nezinsizakalo zoketshezi ezinomfutho ophezulu.
- 1).Uketshezi:Amanzi, isitimu, umoya, uphethiloli ongahluziwe kanye nemikhiqizo kaphethiloli, igesi yemvelo, i-gas condensate, izixazululo zobuchwepheshe, umoya-mpilo, umoya-mpilo, uketshezi kanye namagesi angewona anamandla.
- 2).Izinhlelo zamanzi zokupholisa ezidinga ukuhlukaniswa kanye nokulawulwa kokugeleza.
- 3).Amapayipi aphakeme kanye namapayipi aphansi.
- 4).Izimbobo zamabhoyili namadrayini, Izinkonzo ze-Steam, izimbobo ezinkulu zesitimu kanye namadrayini, namapayipi okufudumeza.
