I-valve yeglobe ye-SDNR yezimboni esezingeni eliphezulu Umkhiqizi womhlinzeki wefektri waseShayina Umkhiqizi
Iyini ivalvu yeglobe ye-SDNR?
I-valve yembulunga ye-SDNRiklanywe futhi yakhiqizwa ngokwezinga langaphambilini laseJalimane, i-DIN kanye nezinga laseYurophu lanamuhla i-EN13709.isetshenziswa kakhulu emazweni ase-European Union.
ivalvu yayo yokuvala ehamba kancane esetshenziswa ukuqala, ukumisa noma ukulawula ukugeleza kusetshenziswa ilungu lokuvala elibizwa ngokuthi idiski. Ukuvulwa kwesihlalo kuyashintsha ngokuhambisana nokuhamba kwediski okulungele imisebenzi ehilela ukulawulwa kokugeleza. Amavalvu e-DIN-EN Globe afaneleka kakhulu futhi asetshenziswa kabanzi ukulawula noma ukumisa ukugeleza koketshezi noma igesi ngepayipi ukuze kucindezelwe futhi kulawulwe ukugeleza koketshezi futhi ngokuvamile asetshenziswa kumapayipi amancane.
iI-valve yembulunga ye-SDNRingasetshenziswa futhi ngezinjongo zokubhoboza. Imizimba eminingi yamavalvu ahlala yedwa isebenzisa ukwakhiwa kwekheji noma isitayela sokugcina ukuze igcine indandatho yesihlalo, inikeze ukuqondisa kwepulaki yamavalvu, futhi inikeze indlela yokusungula izici ezithile zokugeleza kwamavalvu. Ingashintshwa kalula ngokushintsha izingxenye zokusika ukuze ishintshe isici sokugeleza noma inikeze ukugeleza okuncishisiwe kwamandla, ukunciphisa umsindo, noma ukunciphisa noma ukususa i-cavitation.
ngokuvamile kunezinhlobo ezintathu zomzimba noma imiklamo yazoI-valve yembulunga ye-SDNR:
- 1). Iphethini Ejwayelekile (futhi njengephethini ye-Tee noma i-T – Iphethini noma i-Z – Iphethini)
- 2). Iphethini Eligobile (elaziwa nangokuthi i-Wye Pattern noma i-Y – Pattern)
Izici eziyinhloko zevalvu yembulunga ye-SDNR?
Iphethini ejwayelekile (iphethini eqondile)
Iphethini ye-engeli
Iphethini ejwayelekile enophawu lwe-bellows
- 1). Ibanga elifushane lokuhamba kwediski (stroke) phakathi kwezikhundla ezivulekile nezivaliwe,Amavalvu e-DIN-EN globezilungele uma ivalvu kufanele ivulwe futhi ivalwe njalo;
- 2) .Amakhono okuhle okubopha uphawu
- 3).Kukhona ububanzi bamakhono njengoba etholakala kuphethini ejwayelekile (iphethini eqinile), iphethini ye-Angle, kanye nephethini ye-Wye (iphethini ye-Y).
- 5). Kulula ukulungisa nokulungisa izihlalo, ngezinhloso ezahlukene.
- 6). Ikhono lokulawula kahle i-throttling eliphakathi nendawo, ngokushintsha isakhiwo sesihlalo nediski.
- 7). Isetshenziswa kabanzi kuwo wonke amazwe ase-European Union, nakwamanye amazwe.
- 8). I-Bellows seal iyatholakala uma iceliwe.
Ukulawula ukwakheka kwediski
Ukulinganisa ukwakheka kwediski, i-DN200 nangaphezulu
