valavu yachipata cha bonnet yokwera tsinde

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 ikugwira ntchito yopanga mavavu achitsulo. BFE ndi mtundu wodziwika padziko lonse lapansi, womwe umadziwika ndi kapangidwe kake ka nkhonya komanso mtundu wake. Mu 1996, Valbruna, imodzi mwamakampani akuluakulu aku Italy omwe ali pamsika wazitsulo, adakhazikitsa ulamuliro wonse pa BFE Valveyi imapangidwa ndi mafakitale awiri: kupanga zinthu zamtengo wapatali kunadziwika kwa nthawi yoyamba mufakitale ya Bosisio. Parini, pomwe chitsulo chosapanga dzimbiri mu billet chidalamulidwa mwamtheradi, zinthu zakuthupi ndi njira zopangira zida zidatsimikiziridwanso ndikupangidwa. M'malo mwake, kuyang'ana kwambiri pazabwino ndikokwera, ndipo labotale yoyezetsa yokhala ndi zida zokwanira yakhazikitsidwa kuti iziwongolera zida zisanachitike, panthawi komanso pambuyo popanga. The forgings ndi mbali kukonzedwa mu fakitale yaikulu ya Albano S. Alessandro. Chifukwa mapangidwe a CAD amawongoleredwa, miyezo yapamwamba kwambiri imatha kukwaniritsa miyezo wamba komanso zomwe makasitomala amafuna. Ma conveyors opangidwa bwino ndi okonzeka amagwiritsidwa ntchito pokonza mavavu ambiri. Panthawi imodzimodziyo, pamene makina akuluakulu a makina ndi kusinthasintha kwa zida kumafunika, makina angapo a CNC amakhala ndi ma valve ochepa. Mandalama akuluakulu atulutsa zotulukapo zabwino, ukadaulo wopanga bwino komanso kuchuluka kwachangu. Kapangidwe kamangidwe: mpaka 1500-API 602, BS 5352, NF M87.412. Kalasi: 2500 ndi 4500-ANSI B16.34. Kapangidwe kamangidwe: ANSI B16.34. Kalasi: mpaka 4,500lbs, muyezo ndi wapadera, wapakatikati kalasi angaperekedwe pa pempho. Kuwotchera kwa matako kumatengera: ANSI B16.25. Msoko wowotcherera kumaso ndi kumaso: ANSI B16.10 kukula kwachidule chachifupi: 1/2in mpaka 12in (kukula kwakukulu kumapezeka mukapempha). Mtundu: Valavu yachiwiri ya mpira kapena valavu yachipata yapawiri yokhala ndi singano yamtundu wa singano yotulutsa mpweya Kuphatikizika kwapadera: ndi valavu yowunikira ndi manja, jekeseni ikhoza kuchitidwa molingana ndi zofunikira Mapangidwe apangidwe: ANSI B16.34; B31.1; B31.3 ndi MSS-SP84. Makalasi: Malinga ndi ANSI B16.34, pazipita 4,500lbs. Kukula kwa doko: Malinga ndi zomwe makasitomala amafuna. Imagwirizana ndi mayeso a API 598 ndi BS 6755. Imagwirizana ndi chilemba cha MSS SP25. Imagwirizana ndi API 6A kapena BS 6755 zofunika pachitetezo chamoto. Kapangidwe kamangidwe: API 6A Mulingo watsatanetsatane wazinthu: PSL 1, PSL2 ndi PSL3 gulu: 2000, 3000, 5000 ndi 10000 PSI Mapangidwe okhazikika: ASME B16.34-BS5351-API 6D. Zidutswa ziwiri kapena zitatu zolumikizira zida zomangika-zolimba mpira-zofewa valavu mpando-anti-boom ndodo kapangidwe ka anti-static device-side entry-fire test oyenerera-pamwamba pawokha ndi ISO 5211-doko lathunthu kapena lochepetsedwa.
