Mpira wa valavu ya mpira umadula, kuwongolera, kugawa ndikusintha mayendedwe amkati mwa payipiyo. Mpira wa valavu uli ndi maubwino ambiri ndipo ndi mtundu watsopano wa valavu womwe umagwiritsidwa ntchito kwambiri. Mavavu a mpira okhala ndi ntchito zosiyanasiyana nthawi zambiri amakhala ndi magawo osiyanasiyana, ndiye mukudziwa kuti ndi mitundu yanji yamagetsi yomwe ilipo?

1. Magawo ake nthawi zambiri amagawika magawo osindikizira ofewa komanso magawo osindikizira olimba.

2. Malo osalongosoka amatenga kulipira, kuponyera ndi kuwotcherera kwazitsulo. Zomwe zimaperekedwa ndi: A105, 304, 304L, 316, 316L, LF2, 42CrMo, 1Cr13, F51, Mone1, 17-4PH, ndi zina.

3. Mpirawo ungagawidwe m'magulu awiri, mipira itatu, mipira inayi, mpira wokhotakhota, mpira woyandama, mpira wokhazikika, V woboola pakati, gawo lolimbitsa thupi, mpira wolimba, mpira wolimba, mpira wopanda pake, ndi zina malinga ndi ntchito. Ndipo imatha kusintha makonda osiyanasiyana osagwiritsa ntchito ogwiritsa ntchito.

Njira zosiyanasiyana zopangira dera

1. Njira yoponyera: Iyi ndi njira yachikhalidwe yosinthira. Pamafunika kusungunuka kwathunthu, kuthira ndi zida zina, komanso malo owerengera akuluakulu ndi anthu ambiri ogwira ntchito, ndalama zambiri, njira zingapo, njira zopangira zovuta, komanso kuipitsa chilengedwe ndi luso la ogwira ntchito munjira iliyonse zimakhudza mtunduwo mankhwala. Vuto la kutayika kwa pore mu gawo silikhoza kuthetsedwa. Komabe, choperekacho ndichachikulu ndipo zinyalala ndizazikulu. Nthawi zambiri zimapezeka kuti zolakwika zomwe zimapangidwira zimapangitsa kuti ziziphwanyidwa pokonza. Ngati mtengo wazogulitsa ukuwonjezeka ndipo mtunduwo sungatsimikizidwe, njirayi siyoyenera fakitale yathu.

2. Kulipira njira: Iyi ndi njira ina yomwe imagwiritsidwa ntchito ndi makampani ambiri okhala ndi ma valve pano. Ili ndi njira ziwiri zokuthandizira: imodzi imagwiritsa ntchito chitsulo chozungulira kuti ichepetse ndikutenthetsera mopanda kanthu, kenako nkuchita makina. Chachiwiri ndikupanga mbale yazitsulo zosapanga dzimbiri pamakina akuluakulu kuti mupeze chopanda kanthu, chomwe chimasungunuka kuti chikhale chopanda kanthu kuti chikonzeke. Njirayi imakhala ndi magwiritsidwe antchito apamwamba, koma chowonjezera chamagetsi Makina osindikizira, ng'anjo yotentha ndi zida zamagetsi za argon akuti zimafunikira ndalama za yuan 3 miliyoni kuti apange zokolola. Njirayi sioyenera ku fakitale yathu.

3. Njira yopota: Njira yopota ndi chitsulo ndi njira yopitilira patsogolo yopanda tchipisi tating'ono, yomwe ili m'nthambi yatsopano yokakamiza. Chili ndi makhalidwe a kulipira, extrusion, anagubuduza ndi anagubuduza, ndipo ali mkulu chuma ntchito magwiritsidwe (Mpaka 80-90%), kupulumutsa kwambiri nthawi processing (1-5 mphindi n'kupanga), ndi mphamvu chuma akhoza kawiri pambuyo kupota. Chifukwa chakulumikizana kwakanthawi pakati pa gudumu lozungulira ndi chophatikizira panthawi yopota, chitsulocho chimakhala chopanikizika m'njira ziwiri kapena zitatu, zomwe ndizosavuta kupunduka. Pansi pa mphamvu yaying'ono, malo ocheperako olumikizirana (mpaka 25- 35Mpa), chifukwa chake, zida ndizocheperako ndipo mphamvu zonse zofunika ndizochepa (zosakwana 1/5 mpaka 1/4 ya atolankhani). Ikuzindikiridwanso ndi mafakitoreti akunja ngati pulogalamu yopulumutsa mphamvu zamagetsi, ndipo imagwiranso ntchito pokonza magawo ena ozungulira. Ukadaulo wopota wakhala ukugwiritsidwa ntchito kwambiri ndikukonzedwa mwachangu kwambiri kunja. Ukadaulo ndi zida ndizokhwima kwambiri komanso zokhazikika, ndipo kuwongolera kosakanikirana kwa makina, magetsi ndi ma hydraulic kumakwaniritsidwa.

Ma Valves a Mpira

The castings a mavavu athu mpira ndi zopangidwa ndi mchenga lokutidwa, ndi maonekedwe kudzikondweretsa, kukula muyezo, ndipo nthawi imodzi akamaumba.
