Ikhwalithi ephezulu Yezimboni ze-SDNR ivalvu yeglobhu Umkhiqizi wefektri waseChina
Iyini i-valve yeglobu ye-SDNR?
I-valve yeglobhu ye-SDNRyakhelwe 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.
iI-valve yeglobhu ye-SDNRingase isetshenziselwe izinjongo zokudonsa futhi.Izindikimba zamavalvu eziningi ezihlezi ngabodwa 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 imiklamoI-valve yeglobhu ye-SDNR:
- 1).Iphethini Ejwayelekile (futhi njengephethini yeTee noma i-T - Iphethini noma i-Z - Iphethini)
- 2).Iphethini e-Oblique (eyaziwa nangokuthi Iphethini ye-Wye noma i-Y - Pattern)
Izici eziyinhloko ze-valve yeglobu ye-SDNR?
Iphethini ejwayelekile(iphethini eqondile)
Iphethini ye-engeli
Iphethini evamile enezimbongolo zophawu
- 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).
- 5).Ukushicilela okulula nokufaka kabusha izihlalo, ngezinhloso ezahlukahlukene.
- I-6) .Amandla aphakathi nendawo ukuya okuhle, ngokushintsha ukwakheka kwesihlalo nediski.
- 7).Isetshenziswa kakhulu kuwo wonke amazwe ase-European Union, nakwamanye amazwe.
- 8).Bellows seal iyatholakala ngokucela.
Ukulawula ukwakheka kwediski
