Mfundo yogwirira ntchito ya valavu, magulu ndi njira zodzitetezera pakuyiyika

Momwe valavu yowunikira imagwirira ntchito

Thevalavu yoyezera imagwiritsidwa ntchito mu dongosolo la mapaipi, ndipo ntchito yake yayikulu ndikuletsa kubwerera kwa sing'anga, kuzungulira kwa pampu ndi mota yake yoyendetsera, komanso kutulutsa sing'anga mu chidebe.

Ma valve owunikira Zingagwiritsidwenso ntchito pamizere yopereka makina othandizira komwe kuthamanga kungakwere pamwamba pa kuthamanga kwa makina akuluakulu. Ma valve oyesera amatha kugwiritsidwa ntchito pamapaipi amitundu yosiyanasiyana malinga ndi zipangizo zosiyanasiyana.

Valavu yowunikira imayikidwa pa payipi ndipo imakhala imodzi mwa zigawo zamadzimadzi za payipi yonse. Njira yotsegulira ndi kutseka diski ya valavu imakhudzidwa ndi momwe kayendedwe ka madzi kamasinthira m'dongosolo lomwe lili; ndipo makhalidwe otseka diski ya valavu ndi awa: Imakhudza momwe kayendedwe ka madzi kamayendera.

Kugawa ma valavu owunikira

1. Valavu yowunikira Swing

Disiki ya valavu yowunikira yozungulira ili ngati diski ndipo imazungulira shaft ya njira yonyamulira valavu. Chifukwa njira yomwe ili mu valavu ndi yolunjika, kukana kwa kayendedwe ka madzi kumakhala kochepa kuposa kwa valavu yowunikira yokweza madzi. Ndi yoyenera kuyenda pang'ono komanso kusintha kosachitika kawirikawiri kwa kayendedwe ka madzi. Komabe, sikoyenera kuyenda pang'onopang'ono, ndipo magwiridwe ake otsekera madzi si abwino ngati a mtundu wonyamulira madzi.

Valavu yoyesera swing imagawidwa m'mitundu itatu: mtundu wa single-lobe, mtundu wa double-lobe ndi mtundu wa multi-lobe. Mitundu itatuyi imagawidwa makamaka malinga ndi kukula kwa valavu.

2. Valavu yoyezera kukweza

Valavu yowunikira momwe diski ya valavu imayendera pakati pa thupi la valavu. Valavu yowunikira yokweza imatha kuyikidwa paipi yopingasa yokha, ndipo mpira ungagwiritsidwe ntchito pa diski ya valavu pa valavu yowunikira yaing'ono yokhala ndi mphamvu yayikulu. Mawonekedwe a thupi la valavu yowunikira yokweza ndi ofanana ndi a valavu yowunikira (ingagwiritsidwe ntchito mofanana ndi valavu yowunikira), kotero mphamvu yake yolimbana ndi madzi ndi yayikulu. Kapangidwe kake ndi kofanana ndi valavu yowunikira, ndipo thupi la valavu ndi diski ndizofanana ndi valavu yowunikira.

3. Valavu yoyezera gulugufe

Vavu yowunikira momwe diski imazungulira pini pampando. Vavu yowunikira diski ili ndi kapangidwe kosavuta ndipo imatha kuyikidwa pa payipi yopingasa yokha, ndipo magwiridwe antchito otseka ndi otsika.

4. Valavu yowunikira mapaipi

Valavu yomwe diski imasunthira pakati pa thupi la valavu. Valavu yowunikira mapaipi ndi valavu yatsopano. Ndi yaying'ono kukula, yopepuka kulemera komanso yabwino paukadaulo wokonza. Ndi imodzi mwa njira zopangira valavu yowunikira. Komabe, mphamvu yolimbana ndi madzi ndi yayikulu pang'ono kuposa ya valavu yowunikira yozungulira.

5. Valavu yoyezera kupsinjika
