Mavavu Otulutsa Amphamvu Kwambiri Othamanga Kwambiri
Cholinga
▪ Kuthamanga kokwanira, kuthamanga kwambiri komanso kutulutsa kothamanga kwambiri komanso valavu yodzipangira imayikidwa pa payipi yolowera ndi payipi yamadzi yozungulira matenthedwe, yomwe imagwiritsidwa ntchito pochotsa mpweya ndi nthunzi mupaipi, kuti athetse kuchuluka kwa madzi. kukana chifukwa cha kusungirako gasi mupaipi ndi kuphulika kwa mapaipi chifukwa cha kuphulika kwa gasi nyundo yamadzi.Pamene vacuum kwaiye mu chitoliro, akhoza basi jekeseni mpweya kuteteza zimbudzi kulowa mu chitoliro ndi mapindikidwe wa woonda-mipanda zitsulo chitoliro.

▪ Pakuperekedwa kwa maukonde operekera madzi akutawuni ndi njira yatsopano yoperekera madzi, kuphulika kwa mapaipi kapena kuwonongeka kwa nyundo zamadzi ndikosavuta kuchitika.Kafukufuku wasonyeza kuti chifukwa chachikulu cha ngoziyi ndi kusatopa kwa mapaipi.Komabe, valavu yopangira gasi yothamanga kwambiri (kuphatikiza valavu yotulutsa madoko awiri ndi valavu yotulutsa ma port awiri) imatha kutulutsa mpweya wosapanikizika kwambiri.Ndizosapeŵeka kuti pali mizati yambiri yamadzi m'mapaipi ambiri, makamaka m'mapaipi atsopano.Choncho, valavu wamba mkulu-liwiro (kawiri doko) utsi singakwanitse zosowa za utsi wa mapaipi, kuchititsa kuphulika kwa mapaipi madzi m'tawuni.Ngozi zimachitika pafupipafupi.
▪ Valavu yotulutsa mpweya wothamanga kwambiri imakhala yosiyana ndi valavu wamba yothamanga kwambiri (double port) mwadongosolo.Mpweya womwe uli mu payipi ukhoza kutulutsidwa kuchokera ku payipi pa liwiro lalikulu mosasamala kanthu kuti pali mizati yambiri ya madzi, mizati ya mpweya ndi interphase, komanso ngati pali kupanikizika kapena ayi.Kugwiritsa ntchito valavu iyi kumachepetsa chiopsezo choyesa payipi yanu yatsopano komanso kuvutikira kwa mpweya;Chepetsani ngozi zapaipi kuphulika kwa netiweki ya chitoliro, kuchepetsa kukana, kupulumutsa mphamvu, kuchepetsa kugwedezeka, ndikuwongolera chitetezo ndi kudalirika kwa dongosolo lonse loperekera madzi ndi zida zosiyanasiyana.

Vavu Yotulutsa Yophatikizika (ya Madzi Oyera)
▪ Mavavu ophatikizira ophatikizika awa ndi oyenera kuyika popopa kapena mapaipi operekera madzi ndi kugawa.Amagwiritsidwa ntchito pochotsa mpweya wochuluka wopezeka mu payipi, kapena mpweya wochepa womwe umasonkhanitsidwa pamalo apamwamba a payipi umatulutsidwa mumlengalenga, kuti apititse patsogolo ntchito yabwino ya payipi ndi mpope.Pakakhala kupanikizika koyipa mu chitoliro, valavu imayamwa mwachangu mumlengalenga kuti iteteze payipi ku kuwonongeka komwe kumachitika chifukwa cha kupanikizika koyipa.
Vavu Yophatikizira Exhaust (Yachimbudzi)
▪ Poganizira mawonekedwe a zinyalala, valavu yotulutsa zimbudzi imatenga kapangidwe kake koyandama komwe kamagwira ntchito pa pistoni yowulungika kudzera pa pulagi ya pamwamba, yomwe imachepetsa kutulutsa kwa zinyalala panthawi yautsi wambiri, kuti dothi lisatayike pa. kusindikiza pamwamba pa pisitoni, ndipo kumagwirizana kwambiri ndi madzi ndipo sikophweka kuwononga amkati, kotero kuti ntchito yotulutsa mpweya imatha kugwira ntchito bwino.
