Ma Vavu A Mpira Owotchedwa Mokwanira (Mtundu Wokhazikika Wa Cylindrical)
Mawonekedwe
▪ Muyezo Wazinthu: NACE MR0175.
▪ Kuyesa kwa Moto: API 607. API 6FA.
▪ Mawonekedwe a thupi la cylindrical valve ali ndi ubwino wa njira yosavuta yopangira, kusonkhanitsa kosavuta ndi kuikapo, kufa kosavuta kumafunika kuti apange zinthu zopanda kanthu, komanso kugwiritsa ntchito mbale yothandizira kukonza mpirawo.
▪ Maonekedwe a cylinder ndi kuwotcherera: Matupi atatu amasonkhanitsidwa ndi kuwotcherera kudzera muzitsulo ziwiri zofananira zautali kapena matupi awiri amasonkhanitsidwa ndi kuwotcherera kudzera mu weld umodzi wautali.Kapangidwe kameneka kamakhala ndi manufacturability abwino ndipo ndikoyenera kuyika tsinde la valve.Ndikoyenera makamaka kwa lalikulu-diameter onse welded mpira valavu.(matupi aŵiri amagwiritsidwa ntchito ku valavu yaing'ono yaing'ono yonse ya mpira, ndipo matupi atatu amagwiritsidwa ntchito kumagulu akuluakulu onse otsekemera).
▪ Zida zopangira CNC, chithandizo champhamvu chaukadaulo, kufananiza koyenera kwa mapulogalamu ndi zida.
Kapangidwe
Mavavu a Cylindrical Forged Welded Ball (mtundu wathunthu)
Makulidwe
Kugwira ntchito pamanja kwa Worm gear
Kugwiritsa ntchito
▪ Gasi wakumatauni: mapaipi otulutsa mpweya, mzere waukulu ndi mapaipi operekera nthambi etc.
▪ Chotenthetsera: Kutsegula ndi kutseka kwa mapaipi ndi mabwalo.
▪ Malo opangira zitsulo: kasamalidwe ka madzimadzi osiyanasiyana, mapaipi othamangitsira gasi, mapaipi operekera gasi ndi kutentha, mapaipi operekera mafuta.
▪ Zida zosiyanasiyana zamafakitale: mapaipi osiyanasiyana ochizira kutentha, mpweya wosiyanasiyana wamakampani ndi mapaipi amafuta.
Kuyika
▪ Zowotcherera nsonga za ma valve onse achitsulo amatengera kuwotcherera kwamagetsi kapena kuwotcherera pamanja.Kutentha kwambiri kwa chipinda cha valve kuyenera kupewedwa.Mtunda pakati pa malekezero owotcherera usakhale waufupi kwambiri kuti zitsimikizire kuti kutentha komwe kumapangidwa munjira yowotcherera sikudzawononga zinthu zosindikizira.
▪ Mavavu onse ayenera kutsegulidwa panthawi yoikapo.
