Ma seti anayi a phulusa la DN150 la kaboni lachitsulo chachiwirimavavu otulutsa madziAmaliza bwino mayeso onse a ntchito ya fakitale ndipo ali okonzeka kutumizidwa kwa makasitomala. Opangidwa ndi chitsulo cha kaboni cha Q235B, ma valve awa adapangidwa kuti agwire ntchito bwino pogwiritsa ntchito tinthu tating'onoting'ono tolimba kuphatikiza fumbi ndi phulusa la uvuni. Chipinda chilichonse chadutsa mayeso olimba a kulimba kwa mpweya komanso mayeso obwerezabwereza otseka, zomwe sizinaphule kanthu. Makanema athunthu oyesera adaperekedwa kwa makasitomala panthawi yonse yowunikira, ndipo magwiridwe antchito abwino kwambiri otseka mpweya adadziwika bwino.

Chotchedwanso valavu yotulutsa phulusa ya double flap, valavu yotseka mpweya ya double layer, valavu yotulutsa phulusa ya double layer imagwira ntchito ngati zida zofunika kwambiri zotulutsira mpweya pa ma hopper a fumbi, makina otumizira phulusa la pneumatic, ma uvuni achitsulo, mafakitale owotcha zinyalala ndi mizere yopanga ufa wa zinthu zomangira. Chokhala ndi ma flaps apamwamba ndi apansi omwe amatsegula ndi kutseka mosinthana, flap imodzi imakhalabe yotsekedwa ikatulutsidwa. Kapangidwe kake kamatseka kuyenda kwa mpweya, kumathandiza kutulutsa phulusa kosalekeza pamene makinawo akusunga mphamvu yoipa, komanso kumaletsa kuyenda kwa mpweya wotuluka m'madzi ndi kutayika kwa mphamvu.

Mtundu wa DN150 uwu umabwera ndi mphamvu zodabwitsa. Thupi la valavu limapangidwa ndi chitsulo cha kaboni cha Q235B chokhala ndi mphamvu zambiri zomangira komanso mphamvu zolimba zotsutsana ndi fumbi. Malo otsekera opangidwa ndi makina opangidwa bwino amatsimikizira kuti ntchito yake ndi yokhazikika komanso nthawi yayitali yogwirira ntchito. Choyenera phulusa louma, ufa wa mchere, fumbi la flue ndi zinthu zina zouma, valavuyi imathandizira kugwira ntchito yokha nthawi yayitali pamizere yopangira mafakitale.

Vavuyi imagwiritsidwa ntchito kwambiri pochotsa fumbi pogwiritsa ntchito mphamvu ya kutentha, kupanga simenti, kupanga zitsulo, kuwotcha zinyalala zolimba ndi kusonkhanitsa fumbi la mankhwala, ndipo imagwira ntchito zofunika kwambiri monga kutulutsa phulusa ndi kutseka mpweya. Mavavu otulutsa mpweya okhala ndi gawo limodzi nthawi zambiri amataya mpweya zomwe zimachepetsa mphamvu yosonkhanitsa fumbi. Kapangidwe ka mpweya wokhala ndi magawo awiri kamachotsa zoopsa zotulutsa mpweya kuti zitsimikizire kuti dongosolo lonse lochotsa fumbi likugwira ntchito bwino.

Ma valve onse otulutsa phulusa okhala ndi zigawo ziwiri amayesedwa bwino ku fakitale, kuphatikizapo mayeso a switch cycle, kuzindikira kulimba kwa mpweya ndi kuyang'aniridwa kwa kuthamanga. Makanema athunthu oyesera alipo kuti awonetsedwe ndi makasitomala. Timapereka ma valve otulutsa ufa wa mafakitale ndi otseka mpweya ndipo timathandizira kukula ndi zipangizo zomwe zakonzedwa kuti zigwiritsidwe ntchito pa ma valve otulutsa phulusa okhala ndi zigawo ziwiri. Mafunso ochokera kwa akatswiri odziwa ntchito zaukadaulo ndi olandiridwa bwino.
