Amavavu Ovemvane Obubonakancane Okwandisa Amavavu Ovemvane
Izici
Ukwakheka okuhlangene, usayizi omncane, ukufakwa nokugcinwa ngendlela efanele.
▪ Ukusebenza kahle kokulungiswa kwebanga.
▪ Ukubekwa uphawu kuthembekile futhi nempilo yesevisi yinde.
▪ Sekela amadivaysi amaningi okudlulisa.
▪ Hlola ingcindezi:
I-Shell Test Pressure 1.5 x PN
I-Seal Test Pressure 1.1 x PN
Ukucaciswa Kwempahla
| Ingxenye | Okubalulekile |
| Umzimba | I-Cast iron, cast steel, insimbi engagqwali, i-Cr.Mo steel, i-alloy steel |
| Idiski | Cast steel, insimbi engagqwali, Cr.Mo steel, ingxubevange steel |
| Isiqu | 2Cr13, insimbi engagqwali |
| Isihlalo Seal Ring | Insimbi engagqwali, i-multi-layer, i-polyester, i-anti-wear material |
| Ipayipi Lokunweba | I-cast iron, cast steel, insimbi engagqwali, insimbi ye-Cr.Mo |
| Ukupakisha | I-graphite eguquguqukayo, i-PTFE |
Isakhiwo
Isicelo
▪ Amavalvu ovemvane ebona kude asebenzisa i-telescopic rubber sealing structure, esebenza ku-metallurgy, petrochemical, hydropower, imithi, indwangu elula, ukwenza amaphepha, imikhumbi, igesi, ukuphakelwa kwamanzi kanye nokukhipha amanzi, nezinye izinhlelo zamapayipi njengendlela yokuvala uphawu lwe-telescopic.
Iziyalezo
Ivalve yevemvane ye-Telescopic kufanele ibekwe ivundlile.Ungaqhubi ngokuthanda kwakho.
▪ Lapho i-valve uvemvane we-telescopic iphuma efektri, ubude besakhiwo yibo ubude obuncane.Ngesikhathi sokuyifaka, izodonselwa kubude bokuyifaka (okungukuthi ubude bomklamo).
▪ Uma ubude obuphakathi kwamapayipi budlula ubude bokufakwa kwevalve uvemvane lwebonakude, sicela ulungise ukuhlukana kwamapayipi.Ungadonsi ngenkani i-valve ye-telescopic ukuze ugweme ukulimala.
▪ Ivalve yevemvane ye-telescopic ingafakwa kunoma iyiphi indawo.Ukuze uthole isinxephezelo sezinga lokushisa, ngemva kokufakwa kwepayipi, ubakaki bayokwengezwa kuzo zombili iziphetho eduze kwe-eksisi yepayipi ukuvimbela ipayipi le-valve ye-telescopic ukuthi ingakhiphi (bheka uMdwebo 1).Amandla okusekela abakaki azobalwa ngokuvumelana nefomula elandelayo.Kuvinjelwe ngokuphelele ukususa ukwesekwa ngesikhathi sokusebenza.
F>Ps·DN·(kgtf) Isivivinyo: I-PS-pipe test pressure DN-Pipe diameter
▪ Akuvunyelwe ngokuphelele ukuhlakaza i-valve uvemvane yokwandisa endaweni yokwakhiwa kwepayipi.
▪ Ivalve yevemvane ye-telescopic inokusebenza kahle nokubambisana okuqinile.Ungaluleki futhi ufinyeze i-valve uvemvane we-telescopic ngokuphindaphindiwe esizeni.Ngesikhathi sokufakwa kwepayipi, amapayipi emikhawulweni yomibili yevalve yokunweba kufanele agxile, futhi izindawo ezimbili ezivulekile epayipini zizohambisana.
Amabhawodi okulungisa i-flange kufanele abotshwe ngokulinganayo.Ungabophisi ngenkani amabhawodi okulungisa ama-flange ngokuhlangothi olulodwa.
▪ Ipayipi lokunweba kufanele lifakwe ngemuva kwevalvu.
▪ Ingxenye yokunwetshwa yevalve uvemvane enwetshiwe akufanele ifakwe ekhoneni noma ekugcineni kwepayipi.
