Ububanzi obukhuluumshini wokupholisa umoyaye-DN3000 iyisici esibalulekile sokulawula ezinhlelweni ezinkulu zokupholisa umoya kanye nokwelashwa komoya（ivalvu ye-damper yomoya）. Isetshenziswa kakhulu ezimweni ezinezindawo ezinkulu noma izidingo zomoya ophezulu njengezitshalo zezimboni, imigudu yesitimela esingaphansi komhlaba, iziteshi zezindiza, izakhiwo ezinkulu zezentengiselwano, kanye nezitshalo zamandla okushisa. Imisebenzi yayo eyinhloko igxile "ekulawulweni komoya okunembile, ukuqinisekisa ukuzinza kohlelo, kanye nokuthuthukisa ukuphepha kanye nokusebenza kahle kwamandla". Ingahlukaniswa ngokuqondile ngezici ezine:

A. Ukulungiswa okunembile kwevolumu yomoya kanye nomfutho womoya

Ezindaweni ezinkulu, izidingo zokungenisa umoya ezindaweni ezahlukene ziyahlukahluka kakhulu (isibonelo, indawo yokukhiqiza endaweni yokusebenzela yezimboni idinga umoya omningi ukuze kuqedwe ukushisa, kuyilapho indawo yokugcina idinga umoya omningi ukuze kushintshwe umoya). I-valve yomoya ye-DN3000 ingalawula ngokunembile ukuhamba komoya kanye nengcindezi ngepayipi ngokulungisa ukuvulwa kwe-blade, igweme ukuhamba komoya okweqile noma okunganele, iqinisekise ukuthi imingcele yokungenisa umoya endaweni ngayinye ihlangabezana nezindinganiso zokuklama, futhi ngesikhathi esifanayo inciphise umsindo kanye nokusetshenziswa kwamandla okubangelwa ukungalingani kokuhamba komoya ohlelweni.

B. Ukunqunywa komoya wesistimu kanye nokulawulwa kwendawo

Uma izinhlelo ezinkulu zokungenisa umoya zidinga ukulungiswa, zivalwa ezindaweni ezahlukene noma zishintshashintsha izindlela zokusebenza (njengalapho uhlelo lokupholisa umoya lushintsha phakathi kwezindlela zasebusika nezasehlobo), ivalvu ye-damper ye-DN3000 butterfly ingavalwa ngokuphelele ukuze “inqamule futhi ihlukanise” ukuhamba komoya emapayipini noma ezindaweni ezithile ezingakaphathwa, kuvinjelwe umoya ongakaphathwa ukuthi ugeleze futhi uthinte imvelo, kuyilapho kuqinisekiswa ukuphepha kwabasebenzi bokulungisa.

C. Ukuvikelwa Kokuphepha kanye Nokusabela Ezimweni Eziphuthumayo

Ezimweni ezinezingozi zomlilo nokuvuza kwegesi okuyingozi (njengamagaraji angaphansi komhlaba kanye nezitshalo zamakhemikhali), ivalvu yomshini wokucindezela umoya i-DN3000 ivame ukuxhunyaniswa nohlelo lokuvikela umlilo: ivala ngokuzenzakalelayo ama-damper omoya ezindaweni zokukhipha umoya ezingezona intuthu ngesikhathi somlilo ukuvimbela ukusabalala komlilo nentuthu. Lapho amagesi ayingozi evuza, vala ivalvu yomoya endaweni engcolile bese uvula isiteshi sokukhipha umoya ukuze ukhiphe amagesi ayingozi ngokushesha, unciphise izingozi zokuphepha, futhi uhambisane nemithetho yokuvikela umlilo yokwakha kanye nokuphepha kwezimboni.

D. Ukuthuthukisa ukusebenza kahle kohlelo

Uma izinhlelo ezinkulu zokungenisa umoya zisebenza ngokugcwele isikhathi eside, ukusetshenziswa kwazo kwamandla kuzoba phezulu kakhulu. I-DN3000 air valve ingakwazi ukulungisa ngokuguquguqukayo umthamo womoya ngokwezidingo zangempela (njengenani labasebenzi kanye nomthwalo wokukhiqiza), igweme ukumoshwa kwamandla. Okwamanje, ukwakheka kwayo okunobubanzi obukhulu kufanelekile kumapayipi anomthamo omkhulu, kunciphisa ukulahleka kokumelana kokugeleza komoya emzimbeni we-valve, kuqinisekiswe ukusebenza kahle kohlelo lonke lokungenisa umoya, futhi kwehlise umthwalo wokusebenza kanye nezindleko zokugcinwa kwefeni.
