Kusiyana ndi kufanana pakati pa ma valve a zipata, ma valve a mpira, ndi ma valve a butterfly

Kusiyana pakati pa valavu yachipata, valavu ya mpira ndi valavu ya butterfly:

1. Chipata cha valve

Pali mbale yathyathyathya m'thupi la valve yomwe imakhala yolunjika kumayendedwe apakati, ndipo mbale yathyathyathya imakwezedwa ndikutsitsidwa kuti izindikire kutsegula ndi kutseka.

Mawonekedwe: Kuletsa mpweya wabwino, kukana kwamadzimadzi pang'ono, kutsegulira kwakung'ono ndi kutseka, ntchito zosiyanasiyana, ndi machitidwe ena oyendetsera kayendetsedwe kake, komwe nthawi zambiri koyenera mapaipi akulu akulu.

2. Vavu ya mpira

Mpira wokhala ndi dzenje pakati umagwiritsidwa ntchito ngati maziko a valve, ndipo kutsegula ndi kutseka kwa valve kumayendetsedwa ndi kuzungulira mpirawo.

Zomwe Zilipo: Poyerekeza ndi valve yachipata, mapangidwe ake ndi osavuta, voliyumu ndi yaing'ono, ndipo kukana kwamadzimadzi kumakhala kochepa, komwe kungathe m'malo mwa ntchito ya valve.

3. Valve ya butterfly

Gawo lotsegula ndi lotseka ndi valavu yopangidwa ndi diski yomwe imazungulira mozungulira chingwe chokhazikika mu thupi la valve.

Mawonekedwe: Kapangidwe kosavuta, kakang'ono, kulemera kopepuka, koyenera kupanga ma valve akulu akulu.Be amagwiritsidwa ntchito kunyamula madzi, mpweya, gasi ndi njira zina.

1. Malo osindikizira a valve ya mpira ndi ozungulira.

2. Kusindikiza pamwamba pavalavu ya butterflyndi annular cylindrical pamwamba.

3. Malo osindikizira a valve yachipata ndi athyathyathya.
