Vavu ntchito classification valavu gasket mtundu

Mavavu ogwiritsira ntchito gulu la valve gasket mtundu wa valavu yogwiritsira ntchito Universal Mavavu ogwirira ntchito ambiri ndi omwe amapangidwira kuti azigwira ntchito nthawi zambiri omwe ali ndi mphamvu zochepa mu ANSI kalasi 150 mpaka 600 (m'mimba mwake DN16 mpaka DN100) ndi kutentha kwapakati kuchokera -50 mpaka 650H (-46 mpaka 343 c ). Kuwuluka zowononga media ndi kuthamanga wamba kutsika popanda kuchititsa cavitation ndi kung'anima. Ma valve ogwirira ntchito onse amapangidwa ndi kusinthasintha komanso kusinthasintha kuti athe kugwiritsidwa ntchito pazovuta kwambiri. Zida za thupi zimatchulidwa ngati chitsulo cha carbon ndi chitsulo chosapanga dzimbiri. Chithunzi 1.9 chikuwonetsa nthano ya ma valve awiri ogwiritsira ntchito wamba, imodzi yoyendetsedwa pamanja ndi imodzi yokha. Mavavu apadera ogwirira ntchito Ma valve apadera amapangidwa ndi ma valve opangidwa kuti azigwiritsidwa ntchito kamodzi pomwe ntchito zanthawi zonse sizimayembekezereka. Chifukwa cha mawonekedwe ake apadera komanso kupanga kwake, imatha kugwiritsidwa ntchito pokhapokha pazigawo zinazake zogwirira ntchito komanso momwe zimagwirira ntchito. Mbali imeneyi nthawi zambiri imagwiritsidwa ntchito pothana ndi kutentha, kutalika, kapena sing'anga pamayeso achiwiri. CHITH. 1.10 ikuwonetsa valavu yowongolera yomwe idapangidwa ndi thupi lopukutidwa pang'ono ndi spool ya ceramic kuti igwirizane ndi zinthu zomwe zawonongeka kuphatikiza tinthu ta mchenga ndi mpweya wothamanga kwambiri. Valavu yogwira ntchito kwambiri, yomwe ili ndi makhalidwe apadera ogwiritsira ntchito zinthu zowonongeka, jekeseni wa kutsika kwapamwamba kumapangitsa kuti pakhale cavitation, flash, blockage kapena phokoso lalikulu. Valve ikhoza kupangidwa bwino pa globe valve spool. Kapena chimbale chapadera; Kapena mipira yapadera ikhoza kuphatikizidwa mu ma valve ozungulira kuti achepetse kapena kulepheretsa kukhudzidwa panthawi ya ntchito. Kuonjezera apo, ogwira ntchito kapena oyendetsa ndondomeko amafunikira ma actuators apadera kuti athetse mphamvu ya ndondomekoyi. CHITH. 1.11 ikuwonetsa valavu yogwira ntchito yomwe imatha kugwira 1100H (593 c) kashiamu yamadzi yokhala ndi ma spool angapo Gwirani kutsika kwamphamvu kwambiri ndi bonati yapadera yozizirira. Electro-hydraulic actuator imatha kupanga 20,000 lb (889600N) ya thrust. Ma gaskets a valve omwe amagwiritsidwa ntchito kwambiri ndi ma gaskets omwe si achitsulo, ma semi-metal gaskets ndi ma gaskets achitsulo. Non-zitsulo gasket amadziwikanso kuti gasket, monga pepala labala la asbesitosi, mphira, ptfe, etc., gasket kutentha, kuthamanga si mkulu nthawi. Theka-zitsulo gasket wapangidwa ndi zipangizo zitsulo ndi zinthu sanali zitsulo, monga kusinthasintha graphite gulu gasket, mapiringidzo gasket, zitsulo TACHIMATA gasket ndi zina zotero. Semi-metal gasket imakhala ndi kutentha kochulukirapo komanso kupanikizika kuposa gasket yopanda chitsulo. Ma gaskets onse zitsulo amapangidwa ndi zitsulo, kuphatikizapo waveform, mawonekedwe a dzino, elliptic, octagonal, lens pad, cone pad ndi zina zotero. Metal gasket chifukwa cha kutentha kwambiri komanso kugwiritsa ntchito kuthamanga kwambiri. 1 Zoyenera kugwiritsa ntchito ma gaskets osagwiritsa ntchito zitsulo Onani Table 1-4-1 pamikhalidwe yogwiritsira ntchito ma gaskets osagwiritsa ntchito zitsulo dzina lachidziwitso mulingo wa kuthamanga kwa MPA kutentha koyenera ℃ mphira wachilengedwe nr2.0-50 ~90 chlorinated D rabara cr2.0 -40 ~100D mphira wa nitrile nbr2.0-30 ~110 styrene butadiene rabala sbr2.0-30 ~100 ethylene propylene rabala epdm2.0-40 ~130 mphira wa fluorine Viton2.0- 50~200 asbestos 50000000000000000000000000000000000000-200 asbestos asbestos 500000000000000000000000000000000000000000000000000000000000000000000000000-200 labala labala asbesito .t
