Valve yotulutsa yophatikizika

1b Zida zoyambira

Valavu yotulutsa pawiri ndi mbiya yooneka ngati valavu, yomwe imakhala ndi gulu la mipira yachitsulo chosapanga dzimbiri, ndodo ndi mapulagi. Valavuyi imayikidwa pamalo opangira madzi a mpope kapena mupaipi yoperekera madzi ndi kugawa kuti itulutse mpweya wambiri womwe umasonkhanitsidwa mu payipi, kapena mpweya wochepa womwe umasonkhanitsidwa pamalo apamwamba a payipi kupita kumlengalenga, kuti kukonza magwiridwe antchito a mapaipi ndi mpope. Pakakhala kupanikizika koyipa mu payipi, valavu imakokera mpweya wakunja kuti iteteze payipi ku kuwonongeka kobwera chifukwa cha kupanikizika koyipa.

2b Momwe zimagwirira ntchito

Pamene gasi ikusefukira m'dongosolo, mpweya umakwera m'mphepete mwa payipi ndipo potsirizira pake udzasonkhana pamalo okwera kwambiri a dongosolo, pamene valavu yowonongeka nthawi zambiri imayikidwa pamtunda wapamwamba wa dongosolo. Pamene mpweya umalowa m'kati mwa valavu yowonongeka, imasonkhana kumtunda kwa valve yotulutsa mpweya. Ndi kuwonjezeka kwa gasi mu valve, kuthamanga kumakwera. Pamene kupanikizika kwa mpweya kuli kwakukulu kuposa kupanikizika kwa dongosolo, mpweya umapangitsa kuti madzi a m'kati mwake agwere ndikuyandama Pambuyo pa mpweya watha, madzi amatuluka ndipo buoy imakweranso, ndipo doko lotulutsa mpweya limatsekedwa. Momwemonso, pamene kupanikizika koipa kumapangidwa mu dongosolo, mlingo wa madzi mu chipinda cha valve udzatsika ndipo doko lotulutsa mpweya lidzatsegulidwa. Chifukwa mphamvu ya kunja kwa mlengalenga ndi yaikulu kuposa mphamvu ya dongosolo panthawiyi, mpweya udzalowa mu dongosolo kudzera pa doko lotayirira kuti muteteze kuvulaza kwa kupanikizika koipa. Ngati kapu ya valve pa thupi la valavu ya valavu yotulutsa mpweya imatsekedwa, valavu yotulutsa mpweya imasiya kutopa. Kawirikawiri, kapu ya valve iyenera kukhala yotseguka. Valve yotulutsa imatha kugwiritsidwanso ntchito limodzi ndi valavu yotsekera kuti athandizire kukonza valavu yotulutsa yophatikizika.

3b Kapangidwe ndi Kagwiritsidwe

Vavu ndi thupi lamtundu wa mbiya wokhala ndi mpira wosapanga dzimbiri woyandama ndi pulagi mkati.

Valavu imayikidwa potulutsira pampu kapena m'mapaipi operekera madzi ndi kugawa kuti achotse mpweya wambiri womwe umakhala mu payipi, kuti apititse patsogolo magwiridwe antchito a chitoliro chamadzi ndi mpope. Kukanikizidwa koyipa mu payipi, valavu imatha kutulutsa mpweya mwachangu kuti iteteze payipi ku kuwonongeka komwe kumachitika chifukwa cha kupanikizika koyipa.

4b Ubwino

Valavu yowonongeka imakhala ndi ntchito yodalirika ndipo imatha kutulutsa mpweya wambiri mu payipi ndi mpweya wochepa mu ntchito ya dongosolo kupita kunja kwa mpweya mofulumira. Kukonzekera kosavuta, valavu yowonongeka ikhoza kuchotsedwa mosavuta ku dongosolo lokonzekera, ndipo madzi mu dongosolo sangatuluke, kotero palibe chifukwa chochotsera dongosolo. Kutulutsa kokha, kopanda ngalande, nthunzi, madzi kuchokera ku mapangidwe a disk amagwiritsira ntchito dongosolo lapadera kuti atsimikizire kuti palibe ngalande ikatha. Malingana ngati pali kupanikizika mu dongosolo, valavu yotulutsa pawiri idzatha mosalekeza.
