Masiku ano, valavu ya mpweya yozungulira yokhala ndi makona anayi yapangidwa. Kukula kwa valavu iyichopopera mpweyaValavu ndi 2800×4500, ndipo thupi la vavulo ndi lopangidwa ndi chitsulo cha kaboni. Pambuyo poyang'anitsitsa mosamala, antchito akukonzekera kulongedza vavu yamkuntho iyi ndikuikonzekera kuti itumizidwe.

Valavu ya mpweya yozungulira ili ndi kapangidwe kokhazikika komanso kulimba kwambiri. Yapangidwa ndi chitsulo cha kaboni ndipo ili ndi mphamvu zambiri komanso kukana dzimbiri. Imatha kupirira kupsinjika kwakukulu kwa mphepo ndi kugundana kwa mpweya ndipo ndi yoyenera makina opumira omwe amagwira ntchito kwa nthawi yayitali. Kapangidwe kake ka mawonekedwe ozungulira kamagwirizana ndi miyezo ya mafakitale. Pambuyo poyiyika, siimasintha mosavuta ndipo imatha kugwira ntchito mokhazikika m'malo otentha kwambiri, chinyezi chambiri kapena fumbi.

Masamba a louver nthawi zambiri amapangidwa kuti azisinthika. Makona a masamba (0° mpaka 90°) amayendetsedwa ndi ma actuator amanja kapena amagetsi, omwe amatha kusintha molondola kuchuluka kwa mpweya kuti akwaniritse zofunikira pa mpweya m'njira zosiyanasiyana. Mwachitsanzo, m'ma workshop omwe amafunikira kuchuluka kwa mpweya kosalekeza kapena m'makina oziziritsira mpweya omwe amafunika kusinthidwa nthawi yeniyeni malinga ndi momwe ntchito ikuyendera, mphamvu ya mpweya imatha kuyendetsedwa mosavuta.

Chopopera mpweya chopopera mpweya chotchedwa louvered flue ndi choyenera pazochitika zosiyanasiyana, monga m'mafakitale opangira makina, mankhwala, zitsulo ndi zina, komwe fumbi, mpweya wotentha kapena mpweya woipa ziyenera kutulutsidwa munthawi yake. Valavu yopopera mpweya yachitsulo cha kaboni yokhala ndi rectangular louver ikhoza kuyikidwa mu duct yotulutsira mpweya kuti ilamulire mpweya wamkati mwa kusintha kuchuluka kwa mpweya, komanso nthawi yomweyo kuti isawononge mphamvu ya fumbi ndi mpweya wowononga m'malo opangira mafakitale.

Muzochitika zina zopumira moto, zopopera mpweya zachitsulo cha carbon rectangular multi louver zingagwiritsidwe ntchito ngati zida zothandizira utsi wa utsi (mogwirizana ndi zopopera moto). Zitha kutsegulidwa mwachangu kudzera pamanja kapena polumikizirana kuti zitulutse utsi pamalo ozimitsa moto, motero zimapatsa nthawi yoti anthu atuluke komanso kupulumutsa ozimitsa moto.

Ma dampers achitsulo cha kaboni okhala ndi rectangular louver akhala zida zogwiritsidwa ntchito kwambiri m'mafakitale ndi nyumba zapakhomo chifukwa cha kulimba kwawo, kusinthasintha kosinthika komanso ubwino wa ndalama, makamaka oyenera zochitika zomwe mphamvu ya zinthu ndi magwiridwe antchito amtengo wapatali zimafunika. Ngati muli ndi zofunikira zilizonse za ma valve a mpweya, chonde siyani uthenga pansipa kuti mulumikizane ndi antchito a Jinbin. Mudzalandira yankho mkati mwa maola 24!
