Kodi ma valve a butterfly amalowera pawiri? Nthawi zambiri timagawa valavu yagulugufe kukhala mavavu agulugufe a Concentric ndi valavu ya butterfly eccentric.
Tikambirana za ma valve a butterfly bidirectional monga pansipa:

Kodi Concentric butterfly valve ndi chiyani?

Valve yagulugufe yokhazikika imadziwa ngati ma valve agulugufe okhala pansi kapena zero-offset, Ziwalo zawo zikuphatikizapo: Valve body, disc, mpando, tsinde ndi chisindikizo .mapangidwe a valavu ya butterfly ya concentric ndi disc ndipo mpando umagwirizana pakati pa valve, ndipo shaft kapena tsinde ili pakati pa diski. Izi zikutanthauza kuti chimbale chimazungulira mkati mwa mpando wofewa , Zinthu zokhalamo zingaphatikizepo EPDM , NBR Viton Silicon Teflon Hypalon kapena elastomer .

Momwe mungagwiritsire ntchito valavu ya butterfly concentric?

Kupanga valavu ya butterfly ndi yophweka, pali njira zitatu zogwiritsira ntchito makina ogwiritsira ntchito: Lever Handle ya kukula kochepa, Worm Gear box for Larger valves kuti ikhale yosavuta kulamulira ndi Automated operation (kuphatikizapo Magetsi ndi Pneumatic Actuators)
Vavu yagulugufe imagwira ntchito pozungulira disk (kapena vane) mkati mwa chitoliro kuti madzi asamayende bwino. Disk imayikidwa pa tsinde lomwe limadutsa mu thupi la valve, ndipo kutembenuza tsinde kumazungulira disk mwina kutsegula kapena kutseka valavu, Pamene shaft imazungulira, diski imatsegula malo otseguka kapena otseguka pang'ono, kulola kuti madzi aziyenda momasuka .Pamalo otsekedwa, Shaft imazungulira disk kuti itseke kutuluka kwathunthu ndi kusindikiza valve.

Kodi ma valve a butterfly amalowera pawiri?

Bidirectional -njira zimatha kuwongolera kuyenda mbali zonse ziwiri, Monga momwe tinalankhulira, mfundo zogwirira ntchito za ma valve zimatha kukwaniritsa zofunikira.
1 Ndiwotsika mtengo kuposa ma valve ena chifukwa cha kapangidwe kake kosavuta komanso zida zochepera zomwe zimafunikira pakumanga. Kupulumutsa mtengo kumachitika makamaka mu ma valve akuluakulu.
2 Kusavuta kugwiritsa ntchito, kukhazikitsa ndi kukonza, kuphweka kwa agulugufe kumapangitsa kuti ikhale yosavuta komanso yachangu kuyiyika, imatha kuchepetsa mtengo wantchito, Kapangidwe kake kosavuta, kachuma komwe kamakhala ndi magawo ochepa osuntha, motero mavalidwe ocheperako, amachepetsa kwambiri zofunika kukonzanso.
3 Mapangidwe opepuka komanso ophatikizika komanso mawonekedwe ang'onoang'ono amtundu wa agulugufe ang'onoang'ono, Amatha kuyika ndikugwiritsidwa ntchito m'malo opanda malire, amafunikira malo ochepa poyerekeza ndi mitundu ina ya mavavu, monga zipata kapena ma valve a globe, ndipo kuphatikizika kwawo kumathandizira kukhazikitsa ndikugwira ntchito, makamaka pamakina odzaza kwambiri.
4 Kuchita mwachangu, mawonekedwe ozungulira ozungulira (90-degree) amapereka kutsegula ndi kutseka mwachangu. Izi ndizofunika kwambiri pamapulogalamu omwe akufunika kuyankha mwachangu, monga ngati zotseka mwadzidzidzi kapena zokhala ndi zofunikira zowongolera. Kutha kutsegula ndi kutseka msanga kumawonjezera kuyankha kwadongosolo, kupanga mavavu agulugufe omwe ali okhazikika makamaka oyenera kuwongolera kayendetsedwe kake komanso kuwongolera / kutseka pamakina omwe amafuna nthawi yayitali.

Pomaliza, valavu ya gulugufe yomwe ili ndi mbali zonse ziwiri zosindikizira ndi chifukwa cha mawonekedwe ake osindikizira pakati pa mpando wa valve ndi gulugufe, Kuonetsetsa kuti asindikizidwe mosasinthasintha mosasamala kanthu za kayendedwe ka madzi.
