I-Large Bore Metal Seated Gate Valve

Incazelo yomkhiqizo

▪ Idizayini yevalvu ukuya ku-EN1171, DIN3202 F4, BS 5163 njll.
▪ Isiqu esingaphumi, idizayini ephelele, kanye nephaseji elibushelelezi, ukumelana nokugeleza okuphansi
 Isikhathi eside sokushaywa unhlangothi(isikhathi sokuvala) ukugwema isando samanzi
▪ Ukuvala: Vala ngokwewashi
▪ Ukuvalwa kwe-Bi-directional ukwenza ukufaka kube lula.Izinhlangothi zombili zesango ziyalingana.
▪ Umzimba oqinile ku-iron ductile EN GJS 500-7(GGG50), noma 400-15(GGG40), ene-bore enkulu efinyelela ku-DN2000
▪ Umzimba oneziphetho ze-flange X, i-flange drill ku-EN1092-2, BS 4504, DIN2501, njll.
▪ Isango lohlobo lwe-wedge eliqinile elinamandla amakhulu futhi lisesimweni esifanayo emzimbeni
 Amaringi ezihlalo kuwo womabili umzimba kanye nediski ayithusi noma ngethusi esebenza isikhathi eside.
▪ I-Brass noma iBronze (Gunmetal LG2) stem nut kanye nesihlahla
▪ Njengokwesicelo esikhethekile, ikakhulukazi ukufakwa okuvundlile iveluvu yesango elikhulu, Umzimba ungaklanywa ube namaChannel Guides wokuhamba kwesango.Isango lingahlinzekwa ngezicathulo ezishelelayo ngaphakathi kwemihlahlandlela yesiteshi.Iziqondiso nezicathulo ziyingxube yethusi noma ezensimbi engagqwali futhi ziqondisa isango eduze kwebanga eliphelele lokuhamba.Lokho kuzonciphisa ukungqubuzana nokugqoka phakathi komzimba nesango ukuze kwandiswe impilo yesevisi yevalvu.
▪ Amaringi amaningi ama-O ku-stem bushing enza uhlelo oluthembekile lokuvala shaft.
 Inkomishi kawoyela yangaphandle ye-shaft bushing/bearing yakhiwe.
▪ Uhlelo oludidiyelwe lokudlula luzoklanywa njengesicelo esikhethekile.
▪ Izinketho zokusebenzisa: I-bevel gearbox/i-spur gearbox enesondo lesandla noma i-chainwheel,
I-Gearbox isilungele ukuxhunywa ku-actuator kagesi,
I-actuator kagesi
▪ I-Protection Coating: Ukuhlanganiswa kwe-epoxy okuboshiwe okungewona ubuthi emanzini okuphuzwayo kugunyazwe kusukela ku-WRAS/NSF61 ku-DFT 250μm, noma omunye umjikelezo wokupenda.
▪ Eminye imininingwane:

- Umzimba, idiski & impahla yebhonethi: i-ductile iron GJS500-7/GJS400-15/GJS450-10 kuya ku-BS EN 1563

- I-valve stem impahla: insimbi engagqwali 1.4021 (SS420), enye insimbi engagqwali noma izinto zethusi/zethusi ezitholakalayo njengesicelo.

-Isisetshenziswa esifanelekile: ukuphuza amanzi, amanzi amoshekayo/indle, amanzi e-TSE nolunye uketshezi olungagqwali njll.

Izinga lokushisa elifanele: -10 ~ 80 ℃

Ukuhlolwa kwengcindezi ku-EN12266-1 ngezinga lokuvuza lesilinganiso B noma isilinganiso A kuzo zombili izinhlangothi

Ukuhlolwa okungu-100% ngaphambi kokulethwa
