Kuchokera ku mafuta ndi gasi kupita kumalo opangira madzi ndi madzi oipa, ma valve amagwira ntchito yaikulu poyendetsa kayendedwe ka madzi m'mafakitale.Mtundu umodzi wa valavu umene wafala kwambiri m'zaka zaposachedwapa ndi valavu ya gulugufe wamtundu uliwonse.Chopangidwa kuti chipereke kuwongolera kodalirika komanso kolondola, valavu yatsopanoyi imapereka zabwino zambiri kuposa mavavu agulugufe.M'nkhaniyi, tiwona mawonekedwe, maubwino ndi kugwiritsa ntchito ma valve agulugufe atatu.

Valve yagulugufe wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wagulugufe umadziwika ndi dzina lake kuchokera ku mapangidwe ake apadera omwe amaphatikiza ma eccentricities atatu.Zowonongeka izi ndi mtunda pakati pa mpando wapakati ndi shaft centerline, bore centerline, ndi valve centerline.Kapangidwe kameneka kamalola kuti chimbalecho chizizungulira bwino ndikusindikiza mwamphamvu pampando kuti chisatayike.

Mosiyana ndi mavavu agulugufe achikhalidwe pomwe chimbale chimakwirira pampando pakugwira ntchito, valavu yagulugufe yamtundu wa katatu imathetsa kukangana polumikiza chimbale ndi mpando pamakona osiyanasiyana.Kupanga kwatsopano kumeneku kumachepetsa kuvala, kukulitsa moyo wa mavavu ndikuchepetsa mtengo wokonza.

Ubwino waukulu wa katatu eccentric gulugufe valavu ndi hermetic kusindikiza kusindikiza.Chisindikizo cholimba chomwe chimapezedwa ndi valve iyi chimalepheretsa kutayikira kulikonse kosafunikira, kupereka chitetezo chokwanira komanso kudalirika.Izi zimapangitsa kuti zikhale zabwino kwa mapulogalamu omwe kutayikira kungayambitse zoopsa zachilengedwe kapena chiwopsezo chowonjezereka cha kulephera kwa zida.

Ubwino winanso waukulu wa ma valve agulugufe atatu ndi kuthekera kwawo kupirira kutentha ndi kupanikizika.Mapangidwe ndi zipangizo zamapangidwe a valve iyi zimapangitsa kuti zikhale zoyenera kwa mafakitale omwe amagwiritsa ntchito madzi otentha kwambiri, monga magetsi opangira magetsi ndi mafakitale a petrochemical.Kupanga kwake kolimba kumatsimikizira kuti imatha kuthana ndi zovuta zosiyanasiyana, ndikupangitsa kuti ikhale chisankho chabwino kwambiri pakugwiritsa ntchito zovuta.

Kuphatikiza apo, valavu yagulugufe katatu ili ndi kuwongolera bwino kwambiri.Ndi geometry yake yokhala ndi mipando yolondola komanso kapangidwe kake, valavu imapereka kuwongolera koyenda bwino, ngakhale pakuyenda kochepa.Kuwongolera kolondola kumeneku kumawonjezera magwiridwe antchito komanso kumachepetsa kuwononga mphamvu.

Kusinthasintha kwa katatu eccentric butterfly valve ndi mwayi wina womwe suyenera kunyalanyazidwa.Kapangidwe kake kakang'ono, kopepuka kumapangitsa kuti ikhale yosavuta kuyiyika m'mapaipi osiyanasiyana.Kuphatikiza apo, imatha kuyendetsedwa m'machitidwe amanja komanso odziyimira pawokha kutengera zomwe mukufuna.

Mavavu agulugufe atatu opangidwa ndi agulugufe amagwiritsidwa ntchito kwambiri mumafuta ndi gasi, mankhwala, kupanga magetsi, malo opangira madzi ndi madzi oyipa ndi mafakitale ena.Amagwiritsidwa ntchito kwambiri m'mapaipi a gasi ndi madzi, amawongolera bwino kuyenda ndikupatula magawo a mapaipi kuti asamalidwe.Kukhoza kwake kugwiritsira ntchito madzi otentha kwambiri kumapangitsa kuti ikhale yoyenera kupangira magetsi opangira magetsi ndi ntchito zoyenga.Kuphatikiza apo, amagwiritsidwa ntchito kwambiri m'mafakitale opangira madzi kuti azitha kuyendetsa madzi panthawi yoyeretsedwa, kupha tizilombo toyambitsa matenda komanso kugawa.

Pomaliza, valavu yagulugufe katatu ndikupita patsogolo kwaukadaulo pantchito yowongolera kuyenda.Ndi mapangidwe ake apadera, amatsimikizira kusindikiza kwa hermetic, kuwongolera bwino kwambiri komanso kutha kuthana ndi kutentha kwakukulu ndi zovuta.Kusinthasintha kwake komanso kusavuta kuyiyika kumawonjezeranso kukopa kwake.Mavavu agulugufe atatu akuwoneka kuti ndi chida chamtengo wapatali pamene mafakitale akupitiriza kufunafuna njira zothetsera kayendedwe kabwino komanso zodalirika.
