M'malo olamulira madzimadzi a m'mafakitale, ma valve a globe akhala akuwoneka ngati chimodzi mwazinthu zodalirika komanso zolondola zowongolera kuyenda. Ku NSW, tikupitilizabe kukankhira malire a uinjiniya popereka mavavu amphamvu kwambiri padziko lonse lapansi omwe amadaliridwa m'mafakitale onse kuphatikiza mafuta & gasi, petrochemical, kupanga magetsi, kukonza madzi, ndi machitidwe a HVAC.
Kodi Globe Valve N'chiyani?
Vavu ya globe ndi valavu yoyenda yomwe imagwiritsidwa ntchito poyambira, kuyimitsa, ndikuwongolera kuyenda. Amatchulidwa chifukwa cha mawonekedwe ake ozungulira, ngakhale mapangidwe amakono amatha kusiyana. Vavu imakhala ndi chinthu chosunthika chamtundu wa disk ndi mpando wa mphete woyima mu thupi lozungulira. Kukonzekera kumeneku kumapereka mphamvu zomveka bwino, zomwe zimapangitsa kuti ma valve a dziko lapansi akhale abwino kuti azitha kuyendetsa bwino kayendedwe komwe kutayikira ndi kutaya mphamvu kuyenera kuchepetsedwa.
Mapulogalamu Ofunika Kwambiri
Ma valve a globe a NSW amagwiritsidwa ntchito kwambiri pamagwiritsidwe pomwe pamafunika kuwongolera kolondola. Malo odziwika bwino ndi awa:
1.Steam ndi condensate machitidwe
2.Chemical ndondomeko mizere
3.Makina amadzi opangira ma boiler
4.Mapaipi amadzi othamanga kwambiri
5.Zozizira zozizira m'mafakitale amagetsi
6.Cryogenic ndi ntchito zotentha kwambiri
Chifukwa cha luso lawo lotha kuyendetsa bwino kuthamanga kwa kuthamanga ndi kutsika kwa kuthamanga, ma valve a globe ochokera ku NSW nthawi zambiri amagwiritsidwa ntchito poyang'anira ma valve olamulira, omwe amagwira ntchito pamanja kapena amayendetsedwa kuti aziwongolera.
Zosankha Zothandizira Pazosowa Zosiyanasiyana
NSW imamvetsetsa kuti kuyanjana kwa zinthu ndikofunikira m'malo owononga komanso opsinjika kwambiri. Ichi ndichifukwa chake mavavu athu apadziko lonse lapansi amapezeka mumitundu yambiri:
✅Chitsulo cha Carbon (WCB, A105): Ndioyenera kugwiritsidwa ntchito pamafakitale ambiri.
✅Chitsulo chosapanga dzimbiri (CF8M, CF3, CF3M, F304/F316): Kukana kwabwino kwa dzimbiri pakugwiritsa ntchito mankhwala ndi chakudya.
✅Zitsulo za Aloyi (WC6, WC9, C12A): Zapangidwira kutentha kwambiri, ntchito yothamanga kwambiri m'mafakitale amagetsi ndi zoyenga.
✅Bronze ndi Brass Alloys: Nthawi zambiri amagwiritsidwa ntchito m'madzi am'madzi, amchere, komanso popaka nthunzi yocheperako.
✅Duplex ndi Super Duplex Stainless Steels: Mphamvu zazikulu komanso kukana kwa dzimbiri kwapamwamba m'madzi a m'nyanja ndi m'madera akunyanja.
Kuphatikiza apo, timapereka zowongolera makonda, zida zatsinde, ndi zosankha za gasket kutengera mtundu wa media, gulu la kupanikizika, ndi momwe amagwirira ntchito.
Makulidwe ndi Mayeso a Pressure
Ma valve a NSW globe akupezeka mu makulidwe osiyanasiyana kuyambira ½ ”mpaka 24″, okhala ndi magulu okakamiza kuchokera ku ANSI 150 mpaka ANSI 2500, komanso miyezo ya DIN ndi JIS.
Kuchita ndi Kuthetsa Malumikizidwe
Kuti mukwaniritse zofunikira zenizeni za polojekiti, ma valve a NSW atha kuperekedwa ndi njira zosiyanasiyana zosinthira, kuphatikiza:
1.Wwilo lamanja lamanja
2.Pulogalamu ya pneumatic
3.Actuator yamagetsi
4.Nyengo ya hydraulic actuator
Malumikizidwe omaliza omwe alipo akuphatikizapo:
-Flanged (RF/RTJ)
- Kuwotchera m'chiuno
- Socket weld
-Ulusi (NPT/BSPT)
Khalidwe Lomwe Mungadalire
Mavavu onse a NSW amapangidwa motsatira njira zowongolera bwino, kuwonetsetsa kuti mipando yolimba, kupewa kutayikira, komanso kudalirika kwa makina. Valavu iliyonse imayesedwa mokakamizidwa molingana ndi API 598 kapena ma protocol odziwika ndi kasitomala.
Pokhala ndi zaka zambiri pakupanga ma valve ndi kutumiza kunja, NSW yadzipangira mbiri yaukadaulo, kutumiza mwachangu, ndi mayankho osinthidwa mwamakonda. Kaya mukugwira ntchito yotseka makina oyeretsera, pulojekiti yamagetsi otenthetsera, kapena kukonza zomangamanga, mavavu athu apadziko lonse lapansi amapangidwa kuti azigwira ntchito, ndipo amamangidwa kuti azikhala nthawi yayitali.
Kuti mudziwe zambiri zamitundu yathu yonse ya ma valve padziko lonse lapansi ndikupempha mtengo, pitani:www.nswvalves.com
