Phunzirani kuchokera ku mbiri ya Emerson ya mavavu agulugufe

Mavavu a butterflykupereka njira yabwino yotsekera madzi ndi kuyatsa, ndipo ndi olowa m'malo mwachikhalidwevalve pachipataukadaulo, womwe ndi wolemetsa, wovuta kuyiyika, ndipo supereka ntchito yotseka yolimba yofunikira kuti ipewe kutayikira ndikuwonjezera zokolola. Kugwiritsa ntchito koyambirira kwavalavu butterflyidayamba chakumapeto kwa zaka za m'ma 1800 ndipo idasinthidwa mu 50s ya 20th century kukhala kamangidwe kakang'ono, kopepuka komwe kamathetsa bwino mavuto otuluka.

Mtundu wa Emerson's Keystone unapangaelastomer mndandanda wa vavu agulugufe m'zaka za m'ma 50 m'zaka za m'ma 1900, zokhala ndi mawonekedwe ophatikizika, opepuka kuti akwaniritse zosowa za ogwiritsa ntchito kuti akwaniritse zovuta zotayikira komanso chitetezo. Valve ya elasticvalavu ya butterflyamagwiritsidwa ntchito makamaka m'malo mwa mavavu a pachipata pazipata zotsika komanso kutentha kwapansi, monga zida za fakitale, zomanga za HVAC ndi mafakitale ena omwe amafunikira kusindikiza kwapang'onopang'ono. Ndiwopangidwa ndi mphira komanso wokhazikika, kutanthauza kuti diski ndi tsinde zili pakati pa thupi la valve ndi mapaipi. Chipinda cha valve chimazungulira 90º kuti mutsirize sitiroko kuchokera kutsekedwa kwathunthu mpaka kutseguka kwathunthu ndipo angagwiritsidwe ntchito ndi ma manual, magetsi ndi pneumatic actuators. The actuator amalamulira valavu mbale zochita kuchepetsa kapena kulola kutuluka kwa madzimadzi kudzera chitoliro, ndipo wosuta akhoza kusintha otaya sing'anga chitoliro kudzera dongosolo ulamuliro.

Ndi chitukuko chosalekeza chavalavu yagulugufe yokhala ndi mphira yokhala ndi mphira, gawo la ntchito yake lakulitsidwanso. Ogwiritsa ntchito amatha kuzigwiritsa ntchito potentha, zowononga kwambiri, monga malo owononga pang'ono, chakudya ndi zakumwa, komanso kugwiritsa ntchito mpweya wotentha.

Pofuna kuthana ndi ndondomeko zachitukuko zokhazikika zamasiku ano, kuchepetsa kudalira zitsulo zopangira zitsulo, ndipo nthawi yomweyo zikhale zopepuka ndipo zingagwiritsidwe ntchito popanga dzimbiri, monga zipangizo zomangira, zotengera zonyamula katundu ndi katundu, mapaipi apulasitiki kapena fiberglass, monga komanso kuyeretsa, ozoni kapena demineralizchithandizo chamankhwala.

Mavuto atsopano amsika

Imodzi mwazovuta zomwe makasitomala amagwiritsa ntchito ma valve a butterfly masiku ano ndikugwirizana kwa zinthu zomwe zimagwiritsidwa ntchito ndi zomwe zimagwiritsidwa ntchito. Kuti athane ndi vutoli, opanga ma valve akugwiritsa ntchito matekinoloje atsopano opangira ma valve ndi ma discs, kuwapangitsa kuti azigwiritsidwa ntchito pazofalitsa zankhanza.

Mavavu a butterflyosavomerezeka kwa ntchito zomwe zimafuna kutsika kwakukulu. Komanso, chifukwa chavalavu ya butterflymbale ili mu njira yotuluka, siingagwiritsidwe ntchito pamapulogalamu omwe amafunikira mavavu owongoka. Ndioyenera kuwongolera koma osati kwa omwe amafunikira kusintha pang'ono.

Tikugwirabe ntchito

Emersonvalavu ya butterflyKafukufuku waukadaulo ndi njira zachitukuko sizimayimitsa, kuphatikiza kugwiritsa ntchito zida zatsopano ndi miyezo yamakampani yosinthidwa, chitetezo ndi kupewa kutayikira ndizoyendetsa zake zazikulu. Ogwiritsa ntchito mapeto amapindula ndi moyo wotetezeka, wautali pamtengo wotsika.
