hoʻokahi ala e nānā i ka valve damper butterfly
one way check butterflypahu hoʻoheheʻe
Hoʻokahi ala e nānā ai i ka valve damper butterfly e pili ana i ka valve e wehe a pani koke i ka disc valve ma muli o ke kahe ʻana o ka mea kikowaena ponoʻī, i hoʻohana ʻia e pale i ke kahe hope o ka mea waena. Hoʻohana ʻia ia no ka hoʻoheheʻe ʻana o ke kinoea a me nā kinoea ʻē aʻe. ʻO kāna hana nui ka pale ʻana i ka backflow o ka waena. ʻO ka hana o ka valve check ka mea e hiki ai ke kahe ʻana o ka medium ma kahi ʻaoʻao hoʻokahi a pale i ke kahe i ka ʻaoʻao ʻē aʻe. ʻO ka maʻamau, hana maʻalahi kēia valve. Ma lalo o ka hana o ke kaomi wai e kahe ana i ka ʻaoʻao hoʻokahi, wehe ka disc valve; Ke kahe ka wai ma ka ʻaoʻao ʻē aʻe, ʻo ke kaomi ʻana o ka wai a me ke kaumaha ponoʻī o ka disc valve e hana ma ka noho valve, i mea e ʻoki ai i ke kahe.
