Kodi Ubwino Wa Double Union Ball Valve Ndi Chiyani?

Valavu yamagulu awiri a mgwirizano imathandiza kuti thupi lalikulu la valve lichotsedwe ndikugwiritsidwa ntchito kapena kusinthidwa mofulumira kwambiri, popanda kudula chitoliro.Ngati ma valve awiri ogwirizanitsa mpira aikidwa mbali zonse za mpope kapena zida zina, mabungwe omwe ali pafupi ndi mpope amatha kuchotsedwa ndipo akhoza kuchotsedwa kapena kusinthidwa.

  • Kumapeto kwa mgwirizano kumapangitsa kuti kulumikizana kwa ulusi kukhale kosavuta, chifukwa mapeto a valve amatha kutembenuzidwa mopanda valavu.

 

Kodi Pali Kusiyana Kotani Pakati pa Mgwirizano Umodzi ndi Double Union Ball Valve?

Valavu imodzi yamagulu a mpira imakhala ndi socket yokhazikika pambali yotulutsa valavu, ndipo mgwirizano kumbali yoperekera, pamene valavu yamagulu awiri imakhala ndi mgwirizano kumbali zonse ziwiri.

Valavu imodzi ya mpira nthawi zambiri imagwiritsidwa ntchito kumapeto kwa payipi (mwachitsanzo, mzere wa scour).Valovu yamagulu awiri ogwirizana amagwiritsidwa ntchito nthawi zambiri pakati pa payipi chifukwa thupi lonse la valve limatha kuchotsedwa kuti liwunikenso.

Kodi Vavu Ya Mpira Imakhala Ndi Zabwino Zotani Pazipata Zachipata?

Valavu ya mpira nthawi zambiri imakhala yophatikizika kuposa valve yachipata ndipo imagwira ntchito mwamphamvu kwambiri.Valve ya mpira imakhalanso ndi kutuluka kwathunthu popanda masitepe, pamene valve yachipata imakhala ndi malo omwe zinyalala zimatha kusonkhanitsa.Komabe, valavu yachipata imapereka kuwongolera bwino kwa mitengo yoyenda.

Ubwino Wanji Wovala Mpira Umakhala Ndi Vavu ya Gulugufe?
