Induku yokuxhuma ayinakhandai-valve yokushisa umoya, njengengxenye yokulawula eyinhloko ekungeneni komoya ezimbonini kanye nezinhlelo zokudlulisa umoya womoya, kunezinzuzo eziningi ezibalulekile. Isici sawo esiyinhloko ukushiya ukwakheka kwekhanda le-valve elizimele lamavalvu endabuko edamper. Ngokusebenzisa idizayini edidiyelwe yokudlulisela induku yokuxhuma, ukwakheka okuphelele kwenziwa lula kakhulu, okwenza ivolumu ihlangane. Ingakwazi ukuzivumelanisa nezimo zokusebenza ngesakhiwo semishini eminyene futhi ilondoloze indawo yokufaka.

Ama-dampers avame ukutholakala ezinhlelweni zokungenisa umoya zasefekthri, kumasistimu omoya omusha wemizila engaphansi komhlaba, kanye namapayipi egesi ewuflue yamaboilers. Ama-valve ovemvane asetshenziswa kakhulu kumapayipi okuhambisa amanzi emisebenzi yamanzi, izinhlelo zamanzi ezipholisa umoya, kanye nezixhumanisi zokunqamula uketshezi ezitshalweni ze-petrochemical.

Umehluko obaluleke kakhulu phakathi kwama-air dampers namavalvu ovemvane usekuhambeni kwawo kohlelo lokusebenza kanye nomklamo wokusebenza owumongo. I-flue gas damper igxila ekulawuleni umthamo womoya, ukuqondisa kanye nokunqamula ukugeleza kwamagesi (ikakhulukazi umoya, igesi ephuma emanzini nothuli), kuyilapho amavalvu ovemvane esebenza ngokuyinhloko ukuze acime futhi alawule ukugeleza koketshezi, amagesi noma isitimu. Ngenxa yezici ezihlukene ezimaphakathi nezimo zohlelo lokusebenza, umehluko obalulekile uyakhiwa ngesakhiwo, ukugxilwa kokuvala kanye nezinkomba zokusebenza.

Ngokombono wesakhiwo, ama-damper e-Guillotine ngokuvamile athatha ama-multi-blade, ipulaki yepulaki noma ama-valve ohlobo lwe-baffle. Okunye, okufana nenduku yokuxhuma i-airless air damper, iphinde ithuthukise indlela yokugeleza kwegesi ngokudluliswa kwenduku yokuxhuma. Idizayini yokuvala igxile ekwehliseni “izinga lokuvuza komoya” ukuze kuhlangatshezwane nezidingo zokuzinza kokugeleza komoya ekungeneni komoya, ukususwa kothuli, i-HVAC nezinye izinhlelo. Amavalve ovemvane anomongo wevalvu oyindilinga omise okwediski njengomongo wawo. I-valve core izungeza i-valve shaft ukuze ifinyelele ukuvuleka nokuvala. Umklamo wokuvala ugxile “ekuvimbeleni ukuvuza” futhi kufanele uhlangabezane nezinga elithile lokumelana nokucindezela. Zifanele izimo zokuthutha uketshezi ezifana nokuhlinzekwa kwamanzi kanye ne-drainage, imboni yamakhemikhali, namapayipi ashisayo.

Ngokuphathelene nezinkomba zokusebenza, ama-valve omoya anaka kakhulu ukunemba kokulawulwa kwevolumu yomoya kanye nokumelana nokuguguleka kothuli ukubhekana nokuguga kwezingxenye ezibangelwa ukugeleza komoya okunothuli. Ama-valve e-Butterfly agcizelela kakhulu isivinini sokuvula nokuvala, ukumelana nokucindezela nokusebenza kokuvala, kanye nempilo yesevisi. Amanye ama-butterfly valves anengcindezi ephezulu nawo adinga ukuba namandla okumelana ne-cavitation.
