Chovala chokongola chachitsulo chopangidwa ndi ductile chitsulo chokhala ndi valavu yapamwamba kwambiri ya gulugufe ya CF8/CF8M yochokera ku fakitale yaku China

Valavu ya Gulugufe ya Concentric iwiri: ma valve a gulugufe ozungulira okhala ndi flange ali ndi udindo wofunikira chifukwa cha kusinthasintha kwawo komanso kugwira ntchito bwino. Nkhaniyi ikufuna kuwunikira kufunika ndi makhalidwe a valavu yapaderayi, makamaka pankhani yosamalira madzi. Kuphatikiza apo, tikambirana momwe kugulitsa mwachindunji ma valve akuluakulu a gulugufe ozungulira okhala ndi flange okhala ndi flange kumaperekera zabwino zosayerekezeka pamtengo ndi mtundu. Chodziwika ndi kapangidwe kake kosavuta koma kogwira mtima, valavu iyi imakhala ndi diski yomwe imayikidwa pakati pa malekezero awiri a flange. Kutseka kolimba pakati pa diski ndi thupi kumatsimikizira kuti kutayikira kochepa, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito komwe kumafuna kutsekedwa kwathunthu. Kuphatikiza apo, kapangidwe kake kakang'ono komanso kulemera kwake kopepuka kumathandiza kuyika ndi kukonza mosavuta.

Ponena za kukonza madzi, ma valve a gulugufe ozungulira omwe ali ndi flange akuwoneka kuti ndi chuma chamtengo wapatali kumakampaniwa. Pamene kufunika kosamalira bwino madzi kukupitirirabe, valve iyi yakhala yankho lodalirika. Imagwiritsidwa ntchito kwambiri popereka madzi, kukonza zimbudzi, kuchotsa mchere m'madzi ndi madera ena. Kutha kwake kulamulira bwino kayendedwe ka madzi ndikuwonetsetsa kuti kuthamanga kwa madzi kutsika pang'ono kumapangitsa kuti ikhale gawo lofunikira kwambiri m'malo osamalira madzi.
