Makulidwe O - Lembani Mbale Varve: Chigawo chosinthika

Pneumatic O - Mtundu wa Mpira wa mpira ndi valavu yopanga mafakitale yomwe imagwiritsa ntchito valicatic secutator kuti muyendetse kuzungulira kwa scric disc, yotchedwa mpira. Valayi imapangidwa kuti iongolere madzi amtundu wina, kuphatikizapo magesi, zakumwa, komanso ngakhale ena okhazikika m'mapaipi a mafakitale.

Kapangidwe koyambira kwa chibayo o - lembani valavu ya mpira ndi yosavuta komabe yothandiza kwambiri. Imakhala makamaka ya mpira, mpando wa valavu, valavu ya valavu, komanso chibayo. Mpira uli ndi dzenje pakati pa bwalo lake, lomwe limakhala ngati bwalo (o - lembani), ndipo mpira utazungulira ndi njira yolumikizira pa mapaipi, potero kuwongolera kutuluka.

Mpando wa Valve, womwe umapangidwa ndi zida ngati PTFF (Polytetrafluorothylene) yofewa - mapulogalamu osindikizira kapena zitsulo zolimba, zimapereka chisindikizo cha valavu pomwe valavu imatsekedwa. Mbande ya valavu imalumikiza mpirawo kwa womugwira wa chibayo, kufalitsa mphamvu yosintha.

Woyeserera wa chibayo, omwe amatha kukhala owirikiza - kuchita kapena kukwatiwa - kugwira ntchito, kumayendetsedwa ndi mpweya. Ochitapo kanthu - ochita sewero amagwiritsa ntchito ziwopsezo zonse kuti atsegule ndikutseka valve, pomwe osakwatiwa - ochita masewera olimbitsa thupi amagwiritsa ntchito njira imodzi (mwina kutseka) ndi kasupe wobwerera. Kapangidwe kameneka kamathandiza makamaka pakugwiritsa ntchito komwe kulephera - kugwira ntchito motetezeka ndikofunikira. Mwachitsanzo, mu umodzi - kasupe - wogwira ntchito, ngati pali kutaya mtima kwa mpweya, kasupe amangosuntha valavu kuti isachitike, kaya otsekeka kwathunthu kapena kutseka, kutengera njira zachitetezo cha magwiridwe antchito.
