Mfundo yogwirira ntchito ya dziko lapansivalavu:

Madzi amalowetsedwa kuchokera pansi pa chitoliro ndikutulutsidwa kupita kukamwa kwa chitoliro, poganiza kuti pali mzere woperekera madzi wokhala ndi chivundikiro. Chivundikiro cha chitoliro chotulukira chimagwira ntchito ngati njira yotsekera valavu yoyimitsa. Madziwo adzatulutsidwa panja ngati chivundikiro cha chitolirocho chakwezedwa ndi manja. Madziwo adzasiya kusambira ngati chivundikiro cha chitolirocho chaphimbidwa ndi dzanja lanu, zomwe zikufanana ndi ntchito ya valavu yoyimitsa.

Makhalidwe a valavu ya globe:

Ikayikidwa, imakhala ndi madzi ochepa komanso otsika, madzi ake amatuluka molunjika, madzi ake sagwira ntchito bwino, imapanga bwino komanso imakonzedwa mosavuta, kapangidwe kake kosavuta, imapangidwa bwino kwambiri; imagwiritsidwa ntchito makamaka m'mapaipi amadzi otentha ndi ozizira komanso nthunzi yothamanga kwambiri; siigwiritsidwa ntchito. Zosungunulira zokhala ndi tinthu tating'onoting'ono komanso kukhuthala kwakukulu.

Mfundo yogwirira ntchito ya valve ya mpira:

Malo ozungulira omwe ali pamalo olowera ndi otuluka ayenera kuonekera bwino pamene valavu ya mpira yazungulira madigiri 90. Pamenepo, valavu imatsekedwa kuti chosungunuliracho chisamire kusambira. Payenera kukhala mipata ya mipira pakhomo ndi pamalo olumikizirana pamene valavu ya mpira ikuzungulira madigiri 90, ndipo iyenera kutsegulidwa ndikusambira kuti pasakhale kukana kwa madzi.
Makhalidwe a ma valve a mpira:

Thevalavu ya mpiraNdi yosavuta kugwiritsa ntchito, yachangu, komanso yopulumutsa ntchito. Valavu ya mpira ingagwiritsidwe ntchito ndi madzi omwe si oyera kwenikweni (okhala ndi tinthu tolimba) pongotembenuza chogwirira cha valavu madigiri 90. Izi zili choncho chifukwa madziwo amakhudzidwa ndi pakati pa valavu ikatsegulidwa ndi kutsekedwa. Ndi kayendedwe ka kudula.

Mfundo yogwirira ntchito ya valavu ya chipata:

Mtundu wodziwika bwino wa valavu ndi valavu ya chipata, yomwe nthawi zina imadziwika kuti valavu ya chipata. Mfundo yake yogwirira ntchito yotseka ndi kutseka ndi yakuti malo otsekera chipata ndi mpando wa valavu, zomwe zimagwirizana kuti ziletse kuyenda kwa madzi apakati ndikuwonjezera magwiridwe antchito otsekera pogwiritsa ntchito kasupe kapena chitsanzo chenicheni cha valavu ya chipata, zimakhala zosalala kwambiri komanso zogwirizana. Ntchito yayikulu ya valavu ya chipata ndikuletsa kudutsa kwa madzi kudzera mu payipi.

Makhalidwe a valavu ya chipata:

Kutsekeka kwa ntchito kumaposa kwa valavu yozungulira, kukana kwa madzi ndi kochepa, kutsegula ndi kutseka kumafuna ntchito yambiri, pamwamba pa kutsekeka sipawonongeka kwambiri ndi chosungunulira chikatsegulidwa kwathunthu, ndipo magwiridwe antchito a kutsekeka sachepetsedwa ndi njira yoyendera zinthu. Nthawi yotsegulira ndi kutseka ndi yayitali, kukula kwake ndi kwakukulu, ndipo malo ake amafunika kukhala ochepa. Potsegula ndi kutseka, pamwamba pa kutsekeka pamakhala kusokonekera mosavuta. Mawiri awiriwa a kutsekeka amapereka zovuta pakukonza, kukonza, ndi kupanga.

Chidule cha kusiyana pakati pa ma valve a globe,mavavu a mpirandi ma valve a chipata:

Ngakhale ma valve ozungulira angagwiritsidwe ntchito poyendetsa kayendedwe ka madzi ndi switch yowongolera madzi ndi kudula, ma valve a mpira ndi ma valve a chipata nthawi zambiri amagwiritsidwa ntchito poyendetsa kayendedwe ka madzi ndi kudula ndipo nthawi zambiri amagwiritsidwa ntchito poyendetsa kayendedwe ka madzi. Ndi bwino kugwiritsa ntchito valavu yoyimitsa kumbuyo kwa mita mukafuna kusintha kuchuluka kwa madzi. Ma valve a chipata amagwiritsidwa ntchito poyendetsa kayendedwe ka madzi ndi kudula chifukwa ndi abwino kwambiri. Kapena, pa mapaipi akuluakulu, mafuta otsika mphamvu, nthunzi, ndi madzi, gwiritsani ntchito ma valve a chipata. Kulimba kwake kumafuna kugwiritsa ntchito ma valve a mpira. Ma valve a mpira ndi abwino kuposa ma valve a chipata pankhani ya magwiridwe antchito otetezeka komanso moyo wawo wonse, ndipo angagwiritsidwe ntchito m'malo omwe ali ndi miyezo yokhwima yotulutsira madzi. Ayeneranso kutsegula ndi kutseka mwachangu.
