Kutshanje, i-Jinbin valve igqibile ngempumelelo ukuvelisa i-dn3900 air damper valve kunye ne-square louver damper. I-Jinbin valve yoyise ixesha elinzima. Onke amasebe asebenzisane ukugqiba isicwangciso semveliso.

Ngenxa yokuba i-Jinbin valve inamava kakhulu ekuveliseni i-air damper valve kunye ne-louver damper, isebe lezobugcisa likhawuleze lenze imizobo yemveliso. Isebe lemveliso likwagcina unxibelelwano nesebe lezobugcisa kwaye lisebenza ixesha elongezelelweyo ukuqinisekisa ukuhanjiswa okuhamba kakuhle kwixesha lokwakha. Sebenzisa inkqubo yoxanduva oluphambili, gxininisa amanqaku aphambili, uqonde amanqaku aphambili, uqinise amanyathelo, kwaye unikele ingqalelo ekuphunyezweni. Amasebe emveliso afumana iingxaki aze azisombulule ngexesha. Isebe lemveliso liza kubamba ulwalathiso rhoqo kunye nokucwangcisa iintlanganiso ukuze kuxelwe ukugqitywa komsebenzi othile kanye ngeveki kwaye lihlole kanye ngenyanga. Zonke iindawo ziya kulandelwa ukuze kukhuthazwe imveliso kwaye kuthintelwe ukulibaziseka. Kwinkqubo yemveliso yefektri, yiba nolwazi ngenkqubela ethile yokucubungula inxalenye nganye yesixhobo somatshini, wenze umsebenzi olungileyo ekuqhagamshelweni kweenkqubo eziphezulu nezisezantsi, ukuze kuthintelwe ukuchaphazela umsebenzi olandelayo wokuhlanganisa. Kwiingxaki ezifunyenwe kwinkqubo yokuhlanganisa, nxibelelana ngexesha elifanelekileyo kwaye uququzelele namasebe ezobugcisa, ukuze kuthintelwe ukuphazamisa umjikelo wokuhlanganisa.

Le bhasti yevalvu yomoya kunye ne-louver damper zifike ngempumelelo kwaye zaphumelela kuhlolo lomthengi.

Ivalvu yedamper yomoya kunye nedamper ye-louver zisetyenziswa kwipayipi yegesi equlethe umoya obandayo okanye umoya oshushu yobunjineli bomoya wokungenisa umoya kushishino lweekhemikhali, izixhobo zokwakha, izitishi zamandla, iglasi kunye neminye imimandla, njengesixhobo sokulawula ipayipi yokulawula ukuhamba okanye ukucima kwegesi ephakathi.
