Opanga Mavavu Agulugufe Amagetsi

Ndi chitukuko cha ma valve amagetsi, makampani ambiri odziwika bwino a valve kunyumba ndi kunja amapanga ma valve a magetsi. Mavavu agulugufe amagetsi ndi magawo ofunikira kwambiri pantchito yowongolera makina opangira mafakitale. Ndi yamitundu yosiyanasiyana yamagetsi amagetsi ndi ma valve owongolera magetsi. Amagwiritsidwa ntchito kwambiri mu nsalu, magetsi, petrochemical, kutentha ndi firiji, mankhwala, shipbuilding, zitsulo, makampani kuwala, kuteteza chilengedwe ndi zina. Izi zitha kugwiritsidwa ntchito ngati valavu yodulidwa, valavu yowongolera ndi valavu yamapaipi. Complete Buku kulamulira chipangizo, magetsi kapena pneumatic kufala chipangizo, amene angathe kukumana ndi mikhalidwe yeniyeni ntchito zosiyanasiyana. Imakwaniritsa zofunikira zolimba kwambiri ndipo imatha kugwiritsidwa ntchito kwa nthawi yayitali. Makamaka m'mafakitale opangira zitsulo ndi zombo zapamadzi, ali ndi mbiri yapamwamba kwambiri.

Vavu yagulugufe yamagetsi ndi yoyenera pazochitika zomwe zimafuna kuwongolera kayendedwe kake. Popeza kuthamanga kwa valavu ya gulugufe mu payipi ndi yaikulu, yomwe ili pafupifupi katatu kuposa ya valve ya pachipata, mphamvu ya kutayika kwa payipi paipiyi iyenera kuganiziridwa bwino posankha valavu ya butterfly, ndi kulimba kwa mbale ya butterfly pansi. Kupanikizika kwa mapaipi panthawi yotseka kudzaganiziridwanso. Kuphatikiza apo, malire a kutentha kwa zinthu zotanuka mpando pa kutentha kwakukulu ayenera kuganiziridwa. Kutalika kwa mapangidwe ndi kutalika kwa valavu ya butterfly ndi yaying'ono, kutsegula ndi kutseka kuli mofulumira, ndipo valavu ya butterfly ili ndi makhalidwe abwino olamulira madzimadzi. Mfundo yokhazikika ya valavu ya gulugufe ndiyo yabwino kwambiri popanga mavavu akuluakulu. Pamene valavu ya butterfly ikufunika kuti igwiritsidwe ntchito poyendetsa kayendetsedwe kake, chinthu chofunika kwambiri ndikusankha molondola kukula ndi mtundu wa valavu ya butterfly kuti igwire bwino ntchito. Nthawi zambiri, pakuwongolera, kuwongolera komanso sing'anga yamatope, valavu yagulugufe yapakati imafunikira kutalika kwaufupi komanso kutseguka komanso kutseka (kutembenuka kwa 1/4). Valve yotsika yotsika (kusiyana kwapang'onopang'ono), vavu yagulugufe ndiyofunikira. Valavu ya butterfly imatha kusankhidwa kuti ikhale yosinthika pawiri, ndime yocheperako, phokoso lochepa, cavitation ndi gasification, kutayikira pang'ono kumlengalenga ndi sing'anga yowononga. Pamene kusintha kwa throttling kumafunika pansi pamikhalidwe yapadera yogwirira ntchito, kapena mavavu agulugufe amagwiritsidwa ntchito pansi pazikhalidwe zogwirira ntchito monga kusindikiza mwamphamvu, kuvala kwambiri ndi kutentha kochepa (cryogenic), ma valve apadera a butterfly a eccentric atatu kapena awiri okhala ndi chisindikizo chachitsulo chopangidwa mwapadera ndi chipangizo chowongolera. ntchito.
