Kodi Concentric butterfly valve ndi chiyani?

Ma valve agulugufe okhazikika amadziwa ngati ma valve a butterfly okhala pansi kapena zero-offset, mbali zawo zikuphatikizapo: Valve body, disc, mpando, tsinde ndi chisindikizo. tsinde kapena tsinde lili pakati pa chimbale . 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 yomwe imadutsa mu thupi la valve, ndipo kutembenuza tsinde kumazungulira diski kuti itsegule kapena kutseka valve, Pamene shaft imazungulira, diski imatsegula malo otseguka kapena otseguka pang'ono, kulola madzi kuyenda momasuka. Pamalo otsekedwa, Shaft imatembenuza diski kuti itseke kutuluka kwathunthu ndikusindikiza valavu.

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 Kugwiritsa ntchito kosavuta, kukhazikitsa ndi kukonza, kuphweka kwa agulugufe kumapangitsa kuti zikhale zosavuta komanso mofulumira kuyika, zimatha kuchepetsa mtengo wa ntchito, kamangidwe kamene kamakhala kosavuta, kamene kali ndi magawo ochepa osuntha, motero amavala ochepa, amachepetsa kwambiri kukonza kwawo. zofunika.
3 Mapangidwe opepuka komanso ophatikizika komanso mawonekedwe ang'onoang'ono amaso ndi maso a valavu yagulugufe yokhazikika, Yambitsani 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 kuyika ndi kugwira 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 mwachangu kumawonjezera kuyankha kwadongosolo, kupanga mavavu agulugufe omwe ali okhazikika makamaka oyenera kuwongolera kayendetsedwe kake komanso kuyatsa / kuzimitsa 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.
