Ma valve a ngodya amapezeka kwambiri m'nyumba zathu, koma anthu ambiri sadziwa mayina awo. Tsopano tiyeni tikambirane za ubwino wa valavu ya ngodya kuposa mitundu ina ya ma valve. Ingatithandize kusankha bwino posankha ma valve.
Valavu ya ngodya
· Mbali Yaikulu:Malo olowera ndi otulukira amapanga ngodya yakumanja ya madigiri 90.
· Ubwino Waukulu:
- Kumasunga malo oyika: Kapangidwe ka madigiri 90 kamalola kulumikizana mwachindunji ndi mapaipi olowera kumanja, zomwe zimapangitsa kuti zigongono zina zisafunike.
- Njira yosavuta yoyendera madzi, khalidwe labwino lodziyeretsa lokha: Mphamvu yamphamvu yotulutsira madzi imathandiza kupewa kutsekeka.
· Zochitika Zogwiritsira Ntchito: Kukongoletsa nyumba (ma faipu/zimbudzi zolumikizira), machitidwe a mafakitale omwe amafunikira kulumikizana kwa mapaipi a ngodya yakumanja.
· Zoletsa/Zolemba:
- Kugwiritsa ntchito kunyumba: Ntchito yake ndi yosavuta, makamaka posintha ndi kulumikizana.
- Kugwiritsa ntchito m'mafakitale: Kawirikawiri imagwiritsidwa ntchito ngati njira yowongolera valavu, kugogomezera magwiridwe antchito owongolera.
2. Ma valve ogwirira ntchito molunjika (monga ma valve oimitsa olunjika, ma valve okhala ndi mpando umodzi/awiri)
· Mbali yaikulu:Chimake cha valve chimakwera ndi kutsika, ndipo cholowera ndi chotulutsira nthawi zambiri zimakhala molunjika.
· Poyerekeza ndi zofooka za ma valve a ngodya:
- Kukana kwambiri kuyenda kwa madzi ndipo kutsekeka: Njira yoyendera madzi ndi yovuta (yooneka ngati S), pali madera ambiri akufa, ndipo malo osungira madzi amatha kuikidwa.
- Kapangidwe kolemera: Kuchuluka ndi kulemera kwake ndi kwakukulu.
- Chisindikizo cha tsinde la valavu chimawonongeka mosavuta: Kuyenda kobwerezabwereza kwa tsinde la valavu kumawononga mosavuta kulongedza, zomwe zimapangitsa kuti pakhale kutuluka madzi.
· Zochitika Zogwiritsira Ntchito: Zoyenera zochitika zazing'ono zokhala ndi zofunikira zambiri kuti malamulo azitsatira komanso malo owonetsera zinthu zoyera.
3. Valavu ya mpira
· Mbali yaikulu:Chimake cha valavu ndi thupi lozungulira lokhala ndi dzenje lodutsa, ndipo limatseguka ndi kutsekedwa pozungulira madigiri 90.
· Ubwino poyerekeza ndi ma valve a ngodya:
- Kukana madzi pang'ono kwambiri: Pamene madzi atsegulidwa bwino, njira yolowera madzi imakhala pafupifupi chitoliro cholunjika.
- Kutsegula ndi kutseka mwachangu: Kumangofunika kuzungulira madigiri 90 okha.
· Kusiyana ndi ma valve a ngodya:
- Vavu ya ngodya ndi ngodya yolumikizira, pomwe valavu ya mpira ndi mtundu wa njira yotsegulira ndi kutseka. "Vavu ya ngodya ya mpira" imaphatikiza ubwino wa kulumikizana kwa madigiri 90 ndi kutsegula ndi kutseka mwachangu.
· Zochitika Zogwiritsira Ntchito: Zoyenera mapaipi omwe amafuna kutsekedwa mwachangu komanso kutayika kwa mphamvu pang'ono, komanso kugwiritsa ntchito kwambiri.
4. Ma valve owongolera kuyenda kolunjika (monga ma valve ena a ngodya, ma valve a gulugufe, ma valve ozungulira ozungulira)
· Mbali yaikulu:Chimake cha valavu chimazungulira (sichimayenda mmwamba ndi pansi), chomwe chili m'gulu lalikulu.
· Ubwino wonse (poyerekeza ndi ma valve olunjika):
- Kuchita bwino kwambiri poletsa kutsekeka kwa madzi: Njira yolunjika yoyenda, madera ochepa akufa, komanso osatsekeka mosavuta.
- Kapangidwe kakang'ono komanso kopepuka: Kulemera kwake kungachepe ndi 40% - 60%.
- Kutseka kodalirika, nthawi yayitali yogwira ntchito: Chitsinde cha valavu chimangozungulira popanda kusuntha mmwamba ndi pansi, ndipo magwiridwe antchito otseka ndi abwino.
- Kuchuluka kwa madzi oyenda: Mphamvu ya madzi oyenda imakhala yolimba pansi pa mulifupi womwewo.
