Posachedwa, fakitale yamaliza kupanga 31 manualvalavu zakuda. Kuyambira pa kudula mpaka kuwotcherera, ogwira ntchito akupera mosamalitsa. Pambuyo powunikira bwino, tsopano zatsala pang'ono kupakidwa ndikutumizidwa.

Kukula kwa valavu yamagetsi iyi ndi DN600, yokhala ndi mphamvu yogwira ntchito ya PN1. Zapangidwa ndi Q345E carbon steel ndipo zimakhala ndi ma switch owongolera chogwirira. Pachimake cha valavu ya mpweya wokhala ndi chogwirira chimagwiritsidwa ntchito m'makina opumira mpweya kuti asinthe pamanja kuchuluka kwa mpweya ndi kutseguka / kutseka ma ducts. Ndi mawonekedwe ake osavuta, otsika mtengo komanso osafunikira mphamvu zamagetsi, amagwiritsidwa ntchito kwambiri m'maboma, mafakitale, chitetezo chamoto ndi zochitika zina.

M'munda wamafakitale, valavu yamadzimadzi imagwiritsidwa ntchito kwambiri pamakina opangira mpweya wabwino wamakina, malo ochitirako kuwotcherera, ndi zina zambiri, pakutha kwapanyumba kapena kuwongolera nthambi za mpweya. Ogwira ntchito amatha kusintha mwachangu kutsegulira kwa chowongolera chowongolera potengera voliyumu yowotcherera, digiri ya kutentha kwa zida ndi mphamvu zina zantchito, kuwonetsetsa kuti utsi woyipa kapena kutentha kumatulutsidwa munthawi yake. Pakadali pano, mawonekedwe ake amakina amatha kusinthira kumadera ovuta monga fumbi ndi madontho amafuta mumsonkhanowu. Ndizosamva kuvala kuposa zida zamagetsi zamagetsi ndipo ndizoyenera kusintha pafupipafupi pamanja.

Mu dongosolo la kutulutsa utsi wamoto, ndi gawo lofunikira lothandizira lothandizira lomwe limagwirizana ndi malamulo oteteza moto. Nthawi zambiri imayikidwa panthambi zazitsulo zotulutsa utsi kapena malire a zipinda zamoto. Nthawi zonse, mphamvu yotulutsa utsi imatha kusinthidwa pamanja. Pakayaka moto, ngati mphamvu yamagetsi ikulephera, ogwira ntchito akhoza kutseka malo enieni a gasi damper kupyolera mu chogwirira kuti utsi usalowe, kapena kutsegula njira yopopera utsi wa kiyi. Mitundu ina yapadera imakhala ndi zida zokhoma Pewani kugwiritsa ntchito molakwika moto.

Kuonjezera apo, ma valve a mpweya wamanja amagwiritsidwanso ntchito kwambiri m'mabotolo a labotale, mayunitsi ang'onoang'ono a mpweya wabwino ndi zipangizo zina. Mavavu pamanja mpweya anaika pa utsi nthambi mipope ya fume hoods mu labotale. Ogwira ntchito m'ma labotale amatha kukonza mpweya wabwino molingana ndi kuchuluka kwa mpweya woipa kuti asungitse mphamvu yoyipa mkati mwa nduna. Kusintha kolondola kumakhala kosavuta kuposa ma valve amagetsi. Itha kugwiritsidwa ntchito kumapeto kwa mpweya wabwino wapanyumba komanso makatani amphepo amalonda kuti asinthe kuchuluka kwa mpweya, zomwe zingachepetsenso mtengo wa zida ndikuthandizira magwiridwe antchito.
