Valve ya Gulugufe Wachiwiri Wotsutsana ndi Triple Offset Butterfly Valve?

pali kusiyana kotani pakati pa double eccentric ndi triple eccentric butterfly valve?

Kwa mavavu ogulitsa mafakitale, ma valve agulugufe owirikiza kawiri ndi katatu eccentric butterfly valves angagwiritsidwe ntchito mu mafuta ndi gasi, mankhwala ndi madzi, koma pangakhale kusiyana kwakukulu pakati pa mitundu iwiri ya ma valve a butterfly, kotero ndikofunikira kudziwa kusiyana kwake. pakati pa mitundu iwiriyi ya ma valve kuti apange chisankho choyenera.

M'nkhaniyi, tiona kusiyana kwakukulu pakatimavavu agulugufe awirindimavavu agulugufe atatukomanso ubwino ndi ntchito zawo.

Choyamba, mapangidwe ndi zomangamanga ndizosiyana.

Diski yavalavu yagulugufe yawiri eccentricimachotsedwa pakatikati pa thupi la valve ndi shaft.Kapangidwe kameneka kamathandizira kukangana ndi kuvala kwa mpando wofewa wa valve potsegula ndi kutseka, motero kumatalikitsa moyo wautumiki ndikuwongolera kusindikiza.Ngakhale valavu yotchedwa triple eccentric butterfly valve ili ndi gawo lachitatu pamwamba pa eccentric iwiri, mwachitsanzo, imapanga mawonekedwe a conical pamtunda wosindikizira, ndipo zinthu zomwe zili pamwamba pake zimakhala zosindikizira zachitsulo, zomwe zimapangitsa kuti pakhale kusindikiza kwambiri komanso kusindikiza. kukangana kochepa, kumapangitsa kukhala koyenera kwa ntchito zothamanga kwambiri komanso kutentha kwambiri.

Chachiwiri, machitidwewa ndi osiyana.

Mavavu agulugufe atatuperekani maubwino angapo kuposa mapangidwe apawiri eccentric.Mapangidwe a katatu a eccentric amapereka chisindikizo chopanda mpweya, zomwe zikutanthauza kuti kutayikira kumatha kutetezedwa bwino ngakhale pansi pa kupanikizika kwambiri komanso kutentha kwambiri.Chifukwa chake ndizoyenera kwambiri pamapulogalamu ovuta omwe amafunikira kutseka kolimba.Kuphatikiza apo, kamangidwe ka chivundikiro cha agulugufe katatu kamene kamapangidwira kumapangitsa kuti musamavalidwe kotero kuti nthawi yosamalira iwonjezeke ndikuchepetsa mtengo wokonzanso.Ubwino wa magwiridwe antchitowa umapangitsa valavu yagulugufe katatu kukhala chisankho choyamba chofuna kugwiritsa ntchito mafuta ndi gasi, mafakitale a petrochemical ndi magetsi.

Pomaliza, the mtengo womanga sikugwiritsidwa ntchito.

Ubwino waukulu wavalavu yagulugufe yawiri eccentricpoyerekeza ndi katatu eccentric agulugufe vavu ndi kuti mtengo wa zomangamanga ndi otsika pang'ono.Ngati malo ogwirira ntchito safuna kutentha kwambiri komanso kuthamanga kwamphamvu katatu kofanana ndi gulugufe valavu, valavu yagulugufe yamtundu wa Double eccentric ndiyosankha ndalama zambiri.Izi zili choncho chifukwa mavavu agulugufe omwe ali ndi ma eccentric ang'onoang'ono ndi oyenera kugwiritsa ntchito kupanikizika kotsika kapena kwapakati komanso kutentha.Zochita zawo zodalirika komanso zotsika mtengo zimawapangitsa kukhala odziwika bwino pazantchito zosiyanasiyana zamakampani.

Pomaliza, kusankha pakati pawiri ndiatatu eccentric agulugufe mavavuzimadalira zofunikira zenizeni zapakati ndi chilengedwe.Mavavu agulugufe atatu ndi oyenera pamikhalidwe yomwe imafunikira kusindikizidwa kwambiri komanso kukana kupanikizika kwambiri ndi kutentha, pomwe ma eccentric eccentric valves amapereka njira yotsika mtengo pakugwiritsa ntchito movutikira.
