Pankhani yowongolera madzi m'mafakitale, ma valve ozungulira akhala akuonedwa kuti ndi amodzi mwa zinthu zodalirika komanso zolondola kwambiri zowongolera kayendedwe ka madzi. Ku NSW, tikupitilizabe kukankhira malire a uinjiniya popereka ma valve ozungulira ogwira ntchito bwino omwe ndi odalirika m'mafakitale osiyanasiyana kuphatikizapo mafuta ndi gasi, petrochemical, kupanga magetsi, kukonza madzi, ndi machitidwe a HVAC.
Kodi Valavu Yozungulira Ndi Chiyani?
Vavu yozungulira ndi valavu yoyenda molunjika yomwe imagwiritsidwa ntchito kuyambitsa, kuyimitsa, ndikuwongolera kuyenda kwa madzi. Imatchedwa chifukwa cha mawonekedwe ake ozungulira, ngakhale mapangidwe amakono amatha kusiyana. Vavu iyi imakhala ndi chinthu chosunthika cha disk komanso mpando wozungulira wosasuntha m'thupi lomwe nthawi zambiri limakhala lozungulira. Kapangidwe kameneka kamapereka mphamvu zabwino kwambiri zozungulira, zomwe zimapangitsa kuti mavavu ozungulira akhale abwino kwambiri powongolera kuyenda kwa madzi komwe kutayika kwa madzi ndi kuthamanga kuyenera kuchepetsedwa.
Mapulogalamu Ofunika
Ma valve a NSW globe amagwiritsidwa ntchito kwambiri pamene pakufunika kulamulira bwino kayendedwe ka madzi. Malo odziwika bwino ndi awa:
1.Nthunzi ndi makina oundana
2.Mizere ya njira zamakemikolo
3. Makina operekera madzi a boiler
4. Mapaipi amadzi othamanga kwambiri
5. Makina ozizira m'mafakitale amagetsi
6. Ntchito zozizira komanso kutentha kwambiri
Chifukwa cha kuthekera kwawo kopereka ulamuliro wabwino pa kuchuluka kwa madzi ndi kutsika kwa mphamvu, ma valve ozungulira ochokera ku NSW nthawi zambiri amagwiritsidwa ntchito m'makonzedwe a ma valve owongolera, kaya oyendetsedwa ndi manja kapena oyendetsedwa kuti aziwongolera okha.
Zosankha Zipangizo Zofunikira Zosiyanasiyana
NSW ikumvetsa kuti kugwirizana kwa zinthu n'kofunika kwambiri m'malo omwe zinthu zimawonongeka komanso omwe ali ndi nkhawa kwambiri. Ichi ndichifukwa chake ma valve athu a globe amapezeka m'mitundu yosiyanasiyana ya zinthu:
✅Chitsulo cha Kaboni (WCB, A105): Yabwino kwambiri pa ntchito zamafakitale.
✅Chitsulo Chosapanga Dzira (CF8M, CF3, CF3M, F304/F316): Kukana dzimbiri bwino kwambiri pakugwiritsa ntchito mankhwala ndi zakudya zosiyanasiyana.
✅Zitsulo za Aloyi (WC6, WC9, C12A): Yopangidwira ntchito yotentha kwambiri komanso yothamanga kwambiri m'mafakitale amagetsi ndi mafakitale oyeretsera.
✅Ma Alloys a Bronze ndi Brass: Nthawi zambiri amagwiritsidwa ntchito m'madzi a m'nyanja, m'madzi akumwa, komanso m'madzi opanda mphamvu zambiri.
✅Zitsulo Zosapanga Dzimbiri za Duplex ndi Super Duplex: Mphamvu kwambiri komanso kukana dzimbiri m'madzi a m'nyanja ndi m'madera a m'mphepete mwa nyanja.
Kuphatikiza apo, timapereka zokongoletsa zomwe zasinthidwa, zinthu zoyambira, ndi zosankha za gasket kutengera mtundu wa media, kalasi ya kupanikizika, ndi momwe zimagwirira ntchito.
Kukula ndi Kupanikizika
Ma valve a NSW globe amapezeka m'makulidwe osiyanasiyana kuyambira ½” mpaka 24″, ndi magulu opanikizika kuyambira ANSI 150 mpaka ANSI 2500, komanso miyezo ya DIN ndi JIS. Ma valve onse amayesedwa bwino kwambiri ndipo akutsatira ziphaso zapadziko lonse lapansi kuphatikiza API 602, BS 1873, EN 13709, ndi ISO 9001.
Kuyambitsa ndi Kuthetsa Maulumikizidwe
Kuti akwaniritse zofunikira za polojekitiyi, ma valve a NSW globe akhoza kuperekedwa ndi njira zosiyanasiyana zoyendetsera, kuphatikizapo:
1. Chiguduli chamanja choyendetsedwa ndi manja
2. Choyendetsa mpweya
3. Choyatsira magetsi
4. Choyatsira magetsi cha Hydraulic
Maulalo opezeka kumapeto ndi awa:
-Yopindika (RF/RTJ)
-Kulukira matako
-Cholumikizira cha soketi
-Yolumikizidwa (NPT/BSPT)
Ubwino Womwe Mungadalire
Ma valve onse a NSW globe amapangidwa motsatira njira zowongolera khalidwe, kuonetsetsa kuti mipando imakhala yolimba bwino, kupewa kutuluka kwa madzi, komanso kudalirika kwa makina. Valavu iliyonse imayesedwa kuti ipereke mphamvu motsatira API 598 kapena njira zomwe kasitomala akufuna.
Ndi zaka zambiri zaukadaulo wopanga ndi kutumiza ma valve, NSW yadzipangira mbiri yabwino kwambiri paukadaulo, kutumiza mwachangu, komanso mayankho okonzedwa mwamakonda. Kaya mukugwira ntchito yotseka fakitale yoyeretsera mafuta, pulojekiti yamagetsi yotentha, kapena kukonzanso zomangamanga, ma valve athu apadziko lonse lapansi adapangidwa kuti agwire ntchito bwino—ndipo adamangidwa kuti akhale nthawi yayitali.
