Ngati mukuzengereza kusankha mavavu a zipata zachitsulo kapena mavavu achitsulo (WCB), chonde sakatulani fakitale ya zfa valve kuti muwonetse kusiyana kwakukulu pakati pawo.

1. Forging ndi kuponyera ndi njira ziwiri zosiyana processing.

Kuponyera: Chitsulocho chimatenthedwa ndikusungunuka kenaka nkuchithira mumchenga nkhungu kapena nkhungu.Ikaziziritsa, imalimba kukhala chinthu.Mabowo a mpweya amapangidwa mosavuta pakati pa mankhwala.
Forging: Makamaka kugwiritsa ntchito njira monga nyundo pa kutentha kwambiri kuti zitsulo kukhala workpiece ndi mawonekedwe enaake ndi kukula mu pulasitiki boma, ndi kusintha maonekedwe ake thupi.

2. Kusiyana kwa magwiridwe antchito pakati pa mavavu a chipata chonyezimira ndiMa valve a WCB

Panthawi yopangira, chitsulocho chimakhala ndi pulasitiki yosinthika, yomwe imakhala ndi zotsatira zoyenga mbewu, choncho imagwiritsidwa ntchito popanga zinthu zofunika kwambiri.Kuponya kuli ndi zofunikira pazoyenera kukonzedwa.Nthawi zambiri, zitsulo zotayidwa, aluminiyamu, ndi zina zambiri zimakhala ndi zinthu zabwino zoponyera.Kuponya kulibe maubwino ambiri opangira, koma kumatha kupanga magawo okhala ndi mawonekedwe ovuta, motero amagwiritsidwa ntchito popanga zinthu zopanda kanthu zomwe sizimafunikira makina apamwamba kwambiri.

2.1 Kupanikizika

Chifukwa cha kusiyana kwa zinthu zakuthupi, ma valve opangidwa ndi zitsulo amatha kupirira mphamvu zazikulu, ndipo mapulasitiki awo, kulimba ndi zinthu zina zamakina ndizokwera kuposa zaMavavu a WCB.Chifukwa chake, imatha kugwiritsidwa ntchito m'malo opanikizika kwambiri.Zomwe zimagwiritsidwa ntchito nthawi zambiri zopanikizika zazitsulo zopangira zitsulo ndi: PN100;PN160;PN250;PN320;PN400, 1000LB ~ 4500LB.Makanema omwe amagwiritsidwa ntchito mwadzina a mavavu a WCB ndi awa: PN16, PN25, PN40, 150LB~800LB.

2.2 Diameter Nominal

Chifukwa njira yopangirayi imakhala ndi zofunika kwambiri pamapangidwe ndi zida, makulidwe a mavavu opangidwa nthawi zambiri amakhala pansi pa DN50.

2.3 Kuthekera kwa Anti-Leakage

Kutsimikiziridwa ndi ndondomeko yokha, kuponyera kumakonda kutulutsa blowhole panthawi yokonza.Chifukwa chake, poyerekeza ndi njira yopangira, mphamvu yoletsa kutayikira kwa mavavu otayira siabwino ngati mavavu opangira.
Chifukwa chake, m'mafakitale ena omwe ali ndi zofunikira zopewera kutayikira, monga gasi, gasi, mafuta amafuta, mankhwala ndi mafakitale ena, ma valve achitsulo opangidwa akhala akugwiritsidwa ntchito kwambiri.

2.4 Mawonekedwe

Mavavu a WCB ndi mavavu achitsulo opangidwa ndi zitsulo ndizosavuta kusiyanitsa m'mawonekedwe.Nthawi zambiri, mavavu a WCB amakhala ndi mawonekedwe asiliva, pomwe mavavu achitsulo opangidwa amakhala ndi mawonekedwe akuda.

3. Kusiyana m'magawo ofunsira

Kusankhidwa kwapadera kwa ma valve a WCB ndi ma valve achitsulo opangidwa ndi zitsulo kumadalira malo ogwirira ntchito.Sizingatheke kufotokozedwa kuti ndi minda iti yomwe imagwiritsa ntchito mavavu achitsulo opangidwa ndi zitsulo komanso minda iti yomwe imagwiritsa ntchito mavavu a WCB.Kusankhidwa kuyenera kutengera malo enieni ogwirira ntchito.Nthawi zambiri, mavavu a WCB sagonjetsedwa ndi asidi ndi alkali ndipo angagwiritsidwe ntchito pa mapaipi wamba, pamene mavavu achitsulo opangidwa amatha kupirira kuthamanga kwambiri ndipo angagwiritsidwe ntchito m'mafakitale ena omwe ali ndi kutentha kwakukulu, monga magetsi ndi zomera za mankhwala.Valve ya kalasi.

4. Mtengo

Nthawi zambiri, mtengo wa mavavu opangidwa ndi chitsulo ndi wokwera kuposa wa mavavu a WCB.
