Njira zozimitsa moto ndizofunikira poteteza miyoyo ndi katundu ku ngozi zamoto. Chofunikira kwambiri pamakinawa ndi ma valve omwe amagwiritsidwa ntchito kuwongolera, kuwongolera, ndi kuwongolera kuyenda kwamadzi. Kumvetsetsa mitundu yosiyanasiyana ya ma valve ndi maudindo awo mkati mwa dongosolo lotetezera moto ndikofunikira pakupanga ndi kukonza. Pansipa, tiwona ma valve omwe amagwiritsidwa ntchito kwambiri pozimitsa moto.
1. Mavavu a Gate
Ma valve a zipata ndi ena mwa omwe amagwiritsidwa ntchito kwambiri poteteza moto. Ma valve awa amagwira ntchito pokweza chipata (dimba lathyathyathya kapena ngati mphero) kunja kwa njira yamadzi. Zitseko zikatsegulidwa kwathunthu, ma valve a zipata amalola kuti madzi aziyenda mopanda malire, zomwe zimapangitsa kuti azikhala abwino kuzipatula zigawo za network ya mapaipi oteteza moto. Amagwiritsidwa ntchito ngati valavu yotseguka kapena yotsekedwa kwathunthu. Ma valve a zipata, makamaka omwe ali ndi mapangidwe a OS & Y (Outside Screw ndi Yoke), amakondedwa chifukwa malo awo otseguka kapena otsekedwa amatha kutsimikiziridwa mosavuta ndi malo a screw ndi goli.
2. Onani Mavavu
Ma valve owunikira ndi ofunikira kuti mupewe kubwereranso m'makina ozimitsa moto. Amalola kuti madzi aziyenda mbali imodzi yokha, kutsekeka ngati madziwo abwerera. Ntchitoyi ndiyofunikira pakusunga umphumphu wadongosolo ndikupewa kuipitsidwa kapena kuwonongeka. Swing check valves, ndi hinged disk yomwe imatseguka pamene madzi akuyenda m'njira yoyenera, amagwiritsidwa ntchito kwambiri mu machitidwe otetezera moto chifukwa cha kudalirika kwawo ndi kapangidwe kosavuta.
3. Mavavu a Mpira
Mavavu a mpira amagwiritsa ntchito diski yozungulira ("mpira") kuti azitha kuyendetsa madzi. Pamene dzenje la mpira likugwirizana ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake, valavu imatsegulidwa, ndipo pamene mpirawo ukuzungulira madigiri 90, valavu imatsekedwa. Ma valve a mpira amadziwika chifukwa cha kulimba kwawo komanso kusindikiza bwino kwambiri, zomwe zimawapangitsa kukhala abwino kwambiri pakachitika mwadzidzidzi. Nthawi zambiri amagwiritsidwa ntchito m'mapaipi ang'onoang'ono mkati mwa machitidwe otetezera moto ndipo amawayamikira chifukwa cha ntchito yawo yachangu komanso yodalirika.
4. Mavavu a Butterfly
Mavavu agulugufe ndi mtundu wina wa valavu ya quarter-turn yomwe imagwiritsa ntchito disk yozungulira kuti ilamulire kuyenda. Amakhala otchuka kwambiri pamapaipi amitundu yayikulu chifukwa cha kapangidwe kawo kophatikizika komanso kosavuta kugwira ntchito. Mavavu agulugufe nthawi zambiri amakhala opepuka komanso otsika mtengo kuposa ma valve a zipata kapena zapadziko lonse lapansi, zomwe zimawapangitsa kukhala njira yotsika mtengo yowongolera kutuluka kwamadzi munjira zozimitsa moto. Nthawi zambiri amagwiritsidwa ntchito ngati ma valve odzipatula m'makina opopera moto, pomwe zopinga za malo ndi mtengo wake zimaganiziridwa.
Mapeto
Mtundu uliwonse wa valavu muzitsulo zozimitsa moto umagwira ntchito inayake, zomwe zimathandiza kuti chitetezo chonse chikhale chotetezeka komanso chogwira ntchito. Kumvetsetsa maudindo ndi ntchito za ma valvewa kungathandize pakukonzekera bwino, kusankha, ndi kukonza machitidwe otetezera moto. Poonetsetsa kuti ma valve oyenerera akugwiritsidwa ntchito ndi kusungidwa bwino, munthu akhoza kupititsa patsogolo mphamvu ya machitidwe ozimitsa moto, potsirizira pake kuteteza miyoyo ndi katundu ku zotsatira zowononga za moto.
