Pali mitundu itatu ya madzi oipa kapena zonyansa: zonyansa zapakhomo, zonyansa za mafakitale, ndi zimbudzi za mkuntho.Kuchiza kwa zimbudzi kumapangidwa kuti azitsuka ndi kuchiza zinyalala zosaphika pamasitepe osiyanasiyana, kuphatikiza kuphwanya, kusefera, sedimentation, kuwongolera kuwonongeka kwa aerobic ndi chithandizo chamankhwala.
Ukadaulo wamakono wamankhwala azimbudzi ungagawidwe mu chithandizo choyambirira, chithandizo chachiwiri komanso maphunziro apamwamba malinga ndi kuchuluka kwa mankhwala.Nthawi zambiri, kuchuluka kwa zimbudzi kumatha kuzindikirika molingana ndi mtundu wamadzi komanso momwe madzi amayendera.Ma valve omwe amagwiritsidwa ntchito pagawo lililonse ndi osiyana.

Ndiroleni ndidziwitse mavavu omwe COVNA valve angagwiritse ntchito pamakina opangira madzi oyipa

Pneumatic Butterfly Valve

Gulugufe mbale wavalavu ya butterfly ya pneumaticimayikidwa m'mimba mwake ya payipi.Valve ya gulugufe ndi yophweka mwadongosolo, yaying'ono kukula kwake ndi kulemera kwake, ndipo imakhala ndi magawo ochepa okha.Ndipo zimangofunika kuzungulira 90 ° kuti mutsegule ndi kutseka mwamsanga, ndipo ntchitoyi ndi yosavuta.Pamene valavu ya butterfly ili pamalo otseguka, makulidwe a gulugufe mbale ndi kukana kokha pamene sing'anga umayenda mu valavu thupi, kotero kukana kwaiye ndi valavu ndi yaying'ono kwambiri, choncho ali ndi makhalidwe bwino otaya kulamulira ndipo akhoza. kugwiritsidwa ntchito kukonza.Imodzi mwa ma valve omwe amagwiritsidwa ntchito kwambiri pazachimbudzi.Malinga ndi njira yotsegulira, imatha kugawidwa kukhala valavu yagulugufe ndi valavu ya butterfly.
Ubwino: ①Kapangidwe kosavuta, kakulidwe kakang'ono, kulemera kopepuka, zosagwiritsidwa ntchito pang'ono, osagwiritsa ntchito mavavu akulu akulu;②Kutsegula ndi kutseka mwamsanga, kukana kuyenda kochepa;③ Itha kugwiritsidwa ntchito ngati media yokhala ndi tinthu tating'onoting'ono, ndipo itha kugwiritsidwanso ntchito ngati media ndi tinthu tating'ono tolimba, kutengera mphamvu yakusindikiza.Ufa ndi granular media.

Valve yamagetsi yamagetsi

Valve ya mpira imapangidwa kuchokera ku valavu ya pulagi.Lili ndi ntchito yofanana yozungulira madigiri a 90, kupatula kuti thupi la tambala ndi gawo lozungulira lomwe limakhala ndi dzenje kapena njira kudzera muzitsulo zake.Mpira ukazungulira madigiri 90, uyenera kukhala wozungulira polowera ndi potuluka, kuti uchepetse kutuluka.Kukonzekera kotereku kuli koyenera kwambiri kuchimbudzi.Magetsi amagetsi a pvc mpira, magetsi zitsulo zosapanga dzimbiri mavavu mpira, ndi zina zambiri zimagwiritsidwa ntchito.

Ngati mukuchita nawo ntchito yochotsa zimbudzi kapena mukufuna ma valve ochotsa zimbudzi, muthaLumikizanani nafekwa akatswiri ambiri ochotsa zonyansa amadzipangira okha
