Ma Vavu A Mpira Owotchedwa Mokwanira (Mtundu Wokwiriridwa Mwachindunji)
Mawonekedwe
▪ Chigawo chimodzi welded mpira valve, palibe kutayikira kunja ndi zochitika zina.
▪ Ukadaulo wotsogola wapanyumba, wosasamalira komanso moyo wautali wautumiki.
▪ Njira yowotcherera ndi yapadera, yokhala ndi ma pores ofunikira, opanda matuza, kuthamanga kwambiri komanso kutuluka kwa zero kwa thupi la valve.
▪ Pogwiritsa ntchito mpira wapamwamba kwambiri wachitsulo chosapanga dzimbiri, mawonekedwe osindikizira awiri-wosanjikiza, kuthandizira mpira ndi sayansi komanso zomveka.
▪ Gasiketiyo imapangidwa ndi Teflon, faifi tambala, graphite ndi zinthu zina, ndipo imapangidwa ndi mpweya.
▪ Chitsime cha valve ndichotsika mtengo ndipo n’chosavuta kutsegula ndi kugwira ntchito.
▪ Kutalika kwa mwachindunji kukwiriridwa welded mpira valavu thupi angadziŵike molingana m'manda kuya.
▪ Chokhala ndi khomo lojambulira girisi ngati valavu yotchinga yomwe ingalepheretse mafuta osindikizira kuti asabwererenso akapanikizika kwambiri.
▪ Vavu ili ndi zida zolowera, kukhetsa ndi kuteteza molingana ndi zosowa za mapaipi apakati.
▪ Zida zopangira CNC, chithandizo champhamvu chaukadaulo, kufananiza koyenera kwa mapulogalamu ndi zida.
▪ Kukula kwa matako kungapangidwe ndikupangidwa molingana ndi pempho la kasitomala.
Vavu Yowotcherera Mokwanira (Yokwiriridwa Mwachindunji ndi Mtundu Woyamwitsa)
▪ Kugwiritsa ntchito pazigawo zotenthetsera m'chigawo, kuziziritsa ndi kutenthetsa magetsi, gasi wamzinda.
▪ Chapakati: madzi, mpweya, mafuta ndi zinthu zina zamadzimadzi zomwe sizigwirizana ndi chitsulo cha carbon.

Vavu Yowomberedwa Mwathunthu (Yokwiriridwa Mwachindunji Ndi Mtundu Wobalalika)
▪ Kugwiritsa ntchito mapaipi a gasi, gasi wamzinda.
▪ Yapakatikati: gasi wachilengedwe, gasi wamalasha, gasi ndi madzi ena omwe samagwirizana ndi chitsulo cha carbon.

Kukwiriridwa Ntchito Yopanga Mapangidwe
▪ Kwa ma valve omwe amagwiritsidwa ntchito pansi pa nthaka, ikani ndodo zowonjezera valavu, mapaipi owonjezera kuti akonzere (mapaipi otulutsa mbali zonse ziwiri + jekeseni wa mafuta kumbali zonse za mpando wa valve + chimbudzi chamadzi pansi pa thupi la valve) ndi ma valve owongolera kuti apange malo ogwiritsira ntchito valavu pansi Gawo lapamwamba ndilosavuta kugwira ntchito.Zotchingira za phula kapena kutupira kwa epoxy resin pamwamba pa valavu, kulumpha kwa mapaipi pamalopo ndi njira zodzitetezera mwadzidzidzi, kutengera malo okwiriridwawo.
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.
