Ma Vavu A Mpira Owotcherera Mokwanira (Othandizira Kutentha Kokha)
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.
▪ 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.
Kuyesa kwa Moto: API 607. API 6FA
Njira zosiyanasiyana zogwirira ntchito
▪ Mitundu yosiyanasiyana ya ma valve actuators ingaperekedwe: manual, pneumatic, magetsi, hydraulic, pneumatic hydraulic linkage.Chitsanzo chenichenicho chimasankhidwa molingana ndi torque ya valve.

Makulidwe
Vavu Yowotcherera Mokwanira Mpira Yokhala Ndi Mapeto Opindika (Yopereka Kutentha Kokha)
Kugwiritsa ntchito
▪ Kutentha kwapakati: mapaipi otulutsa, mizere yayikulu, ndi mizere ya nthambi ya zida zazikulu zotenthetsera.
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.
