Mavavu ndi zinthu zofunika kwambiri pamapaipi oyendetsa sitima zapamadzi, zomwe zimagwira ntchito yofunika kwambiri pakuwongolera kayendedwe ka madzi, kupanikizika, komanso mayendedwe amadzi muchombo chonsecho. Amathandizira kuwonetsetsa kuti machitidwe osiyanasiyana, kuphatikiza kuziziritsa, ballast, mafuta, ndi kuzimitsa moto, akugwira ntchito moyenera, mosatekeseka, komanso modalirika. Popanda kuwongolera moyenera ma valve, makina amadzimadzi omwe ali m'sitimayo amatha kuwonongeka, kutayikira, ndi ngozi zina zachitetezo. Pano pali kuwonongeka kwa momwe ma valve amathandizira kuwongolera kuthamanga kwamadzi ndi momwe madzi amayendera pamapaipi a sitima zapamadzi.
1. Kuwongolera ndi Kuwongolera
- Mavavu a Mpira: Amagwiritsidwa ntchito powongolera / kuzimitsa kosavuta, ma valve awa amalola kapena kuyimitsa kutuluka kwamadzi mudongosolo potsegula kapena kutseka kwathunthu. Ndiofunikira pakupatula machitidwe okonzekera kapena pakagwa mwadzidzidzi.
- Mavavu a Globe: Awa adapangidwa kuti azilola kuthamanga kwamadzimadzi. Amagwiritsidwa ntchito nthawi zambiri m'malo omwe kayendetsedwe ka kayendedwe kake kamayenera kusinthidwa pafupipafupi, monga m'makina ozizira kapena mizere yamafuta.
2. Kuletsa Kupanikizika
- Ma Vavu Othandizira: Mavavuwa amatseguka kuti atulutse mphamvu ikadutsa poyambira. Pakachitika kuthamanga kwambiri, monga pamafuta kapena mizere ya hydraulic, valavu yopumira imalepheretsa kuwonongeka kowopsa potulutsa bwino mphamvu yochulukirapo.
- Ma Vavu Owongolera Kupanikizika: Awa amagwiritsidwa ntchito kuti asungitse kupanikizika kosasintha mkati mwamtundu wina, ndikofunikira kuti makina omwe amafunikira kukhazikika kokhazikika kuti agwire bwino ntchito, monga makina ozizira a injini kapena makina operekera mafuta.
3. Directional Flow Control
- Yang'anani ma Vavu: Izi zimalepheretsa kubwereranso powonetsetsa kuti madzi amatha kuyenda mbali imodzi. Ndikofunikira kwambiri popewa kuthamangitsidwa kobwerera komwe kungawononge zida kapena kusokoneza magwiridwe antchito. Mwachitsanzo, mu makina a bilge kapena ballast systems, ma valve owunika amalepheretsa madzi a m'nyanja kubwerera m'ngalawamo.
- Mavavu a Njira Zitatu ndi Zosiyanasiyana: Mavavuwa amapangidwa kuti aziwongolera kutuluka kwamadzi munjira zosiyanasiyana. Mwachitsanzo, atha kugwiritsidwa ntchito kusinthana pakati pa mizere yamafuta osiyanasiyana kapena kupatutsira madzi ozizira kumadera osiyanasiyana a injini.
4. Kudzipatula ndi Kutseka
- Mavavu a Zipata: Awa amagwiritsidwa ntchito ngati kutseka kwathunthu, pomwe kuyimitsa kwathunthu kwamadzimadzi kumafunika. Pazochitika zadzidzidzi kapena panthawi yokonza, ma valve a zipata amalola kuti zigawo za mapaipi a sitimayo azidzipatula.
- Mavavu agulugufe: Nthawi zambiri amagwiritsidwa ntchito powongolera kuchuluka kwakuyenda, mavavu agulugufe amagwiritsidwanso ntchito potseka mwachangu. Mapangidwe awo ophatikizika amalola kugwira ntchito mwachangu komanso kusindikiza kogwira mtima.
5. Chitetezo pazadzidzidzi
- Njira Zozimitsa Moto: Mavavu amawongolera kutuluka kwa madzi kapena mankhwala oletsa moto kuti azimitsa moto ngati wayaka. Kutsegula mwachangu komanso kodalirika kwa mavavuwa ndikofunikira kuti muchepetse zoopsa.
- Ma valve Otsekera Mwadzidzidzi: Ma valve awa amapangidwa kuti atseke mwamsanga machitidwe ovuta, monga mizere ya mafuta kapena makina, pakagwa mwadzidzidzi, kuteteza kuwonongeka kapena ngozi.
6. Kulamulira Kuyenda kwa Specialized Systems
- Ballast Systems: Mavavu amawongolera kutuluka kwa madzi a m'nyanja kulowa ndi kutuluka m'matangi a ballast, kuthandiza sitimayo kuti ikhale yokhazikika komanso yogawa kulemera koyenera. Izi ndizofunika kwambiri kuti sitimayo ikhale yabwino, makamaka panthawi yokweza kapena kutsitsa.
- Makina Ozizirira: Mavavu amawongolera kayendedwe ka madzi kudzera m'makina ozizirira a sitimayo kuti atsimikizire kuti injini ndi makina ena amakhalabe m'malo otetezeka.
- Njira Zoperekera Mafuta: M'njira yoperekera mafuta, ma valve amayendetsa kayendedwe ka mafuta kuchokera ku matanki osungirako kupita ku injini, kuwonetsetsa kuti mafuta aperekedwa pa kuthamanga koyenera ndi mlingo woyenera.
