pn16 mphira yokutidwa ndi chitsulo cha diouble disc swing check valve

Timawagwiritsa ntchito kuti tikupatseni chidziwitso chabwino kwambiri. Ngati mupitiliza kugwilitsila nchito webusaiti yathu, tidzaganiza kuti ndinu okondwa kulandila makeke onse pa webusaitiyi.
Kuyambira 1953, BFESpA yakhala ikuyang'ana kwambiri pakupanga mavavu achitsulo. BFE ndi mtundu wolemekezeka padziko lonse lapansi, womwe umadziwika ndi mapangidwe ake apamwamba komanso mtundu wake. Mu 1996, Valbruna, imodzi mwamakampani akuluakulu aku Italy pamsika wazitsulo, idakhazikitsa ulamuliro wonse pa BFE.
Mavavu amapangidwa muzomera ziwiri: kukwaniritsidwa koyamba kwa zinthu zamtengo wapatali kunapezeka mufakitale ya Bosisio Parini, pomwe zitsulo zachitsulo ndi ma billets zidakonzedwanso ndikupangidwira pansi pa ulamuliro wonse, katundu wakuthupi ndi njira zopangira. M'malo mwake, timayika kufunikira kwakukulu kwaubwino ndipo takhazikitsa labotale yoyesera yokhala ndi zida zowongolera zinthu zisanachitike, panthawi komanso pambuyo popanga.
The processing wa forgings ndi zigawo zikuluzikulu ikuchitika mu fakitale yaikulu ya Albano S. Alessandro. Chifukwa cha kapangidwe ka CAD koyendetsedwa, miyezo yodziwika bwino komanso makulidwe amakasitomala amakwaniritsa miyezo yapamwamba kwambiri. Ma conveyors opangidwa bwino ndi okonzeka amagwiritsidwa ntchito pokonza mavavu ambiri. Pa nthawi yomweyi, pamene kusinthasintha kwa makina ndi zida kumafunika, makina angapo a CNC amatha kukonza ma valve ochepa. Ndalama zambiri zatulutsa zotsatira zabwino, luso lamakono lopanga komanso luso labwino.
Kapangidwe kamangidwe: apamwamba kwambiri 1500-API 602, BS 5352, NF M87.412. Kalasi: 2500 ndi 4500-ANSI B16.34.
Kapangidwe kamangidwe: ANSI B16.34. Kalasi: mpaka mapaundi a 4,500, okhazikika komanso apadera, magiredi apakatikati akupezeka popempha.
Kuwotcherera matako kumayenderana ndi: ANSI B16.25. Kutsata kumaso ndi maso: ANSI B16.10 mtundu waufupi. Kukula: 1/2in mpaka 12in (kukula kwakukulu kumapezeka mukapempha).
Mtundu: Valavu iwiri ya mpira kapena valavu iwiri yachipata chokhala ndi singano. Kuphatikiza kwapadera: kumatha kukhala ndi valavu yoyendera ndi manja a jekeseni malinga ndi zofunikira.
Kapangidwe kamangidwe: ANSI B16.34; B31.1; B31.3 ndi MSS-SP84. Maphunziro: Malinga ndi ANSI B16.34. Kukula kwa doko mpaka mapaundi a 4,500: Malinga ndi zomwe makasitomala amafuna.
Maziko oyesera: API 598 ndi BS 6755. Maziko olembera: MSS SP25. Maziko oteteza moto: API 6A kapena BS 6755.
Kapangidwe kamangidwe: API 6A. Mulingo wamatchulidwe: PSL 1, PSL2 ndi PSL3. Gulu: 2000, 3000, 5000 ndi 10000 PSI
Mapangidwe okhazikika: ASME B16.34-BS5351-API 6D. TS EN ISO 5211 bawuti yokhala ndi zida ziwiri kapena zitatu-zokhazikika pampando-zophulika-proof valve tsinde yovomerezeka yoyeserera yoyeserera moto - TS EN ISO 5211 doko lodzaza zokha kapena doko lochepetsedwa.
