(1) Mavavu omanga mtawuni: ma valve otsika kwambiri amagwiritsidwa ntchito pamakina omanga m'matauni, ndipo pakali pano akupanga njira yoteteza chilengedwe ndi kupulumutsa mphamvu.

Mavavu amtundu wa rabara, mavavu oyendera bwino, mavavu agulugufe apakati, ndi ma valve agulugufe omata zitsulo pang'onopang'ono akulowa m'malo mwa zipata zachitsulo zotsika.Mavavu ambiri omwe amagwiritsidwa ntchito m'nyumba zam'tawuni ndi mavavu oyendera bwino, ma valve otsekedwa ndi zipata, ma valve agulugufe, ndi zina zambiri.

(2) Mavavu otenthetsera m'tawuni: mavavu agulugufe osindikizidwa ndi zitsulo, ma valve opingasa opingasa ndi ma valve okwiriridwa mwachindunji amafunikira pakuwotcha kwamatawuni.Ma valve awa amathetsa vuto la kusalinganika kwa hydraulic yoyima komanso yopingasa ya payipi, kupulumutsa mphamvu, ndikuchepetsa kutulutsa kutentha.cholinga cha.

(3) Mavavu a gasi wamzinda: Gasi wamumzinda ndi 22% ya msika wonse wa gasi, ndipo kuchuluka kwa ma valve ndi akulu ndipo pali mitundu yambiri.Amafunika kwambiri valavu ya mpira, valavu ya pulagi, valavu yochepetsera kuthamanga, valavu yotetezera.

(4) Mavavu amapaipi aatali: mapaipi aatali amakhala makamaka mafuta amafuta, zinthu zomalizidwa ndi mapaipi achilengedwe.Mavavu omwe ambiri mwa mapaipiwa amafunikira ndi zitsulo zopangira zitsulo zokhala ndi zidutswa zitatu, ma valve oletsa sulfure pachipata, zoyendetsa chitetezo, ndi ma valve owunika.

(5) Mavavu oteteza chilengedwe: Njira yoperekera madzi m'nyumba zotetezera zachilengedwe makamaka imayenera kugwiritsa ntchito valavu yagulugufe wapakati, valavu yachipata, valavu ya mpira, ndi valavu yotulutsa mpweya (zouma kuchotsa mpweya mu payipi, ndi njira yochotsera zimbudzi makamaka imayenera kugwiritsa ntchito valavu ya butterfly yotsekedwa ndi butterfly valve.
