Pono e hoʻokomo i ka valve check ma ka puka o ka paila a ma ke alo o ka pahu hoʻokele puka no ka mālama ʻana.ʻO ka mea maʻamau, ʻo ka puka mua o ka pāpaʻi he pilina palupalu (mea hoʻopaʻa haʻalulu), a ukali ʻia e ka valve check, a laila poloka i ka valve (e like me ka valve butterfly, valve gate, stop valve, etc.).
1. E hoʻokomo mua i ka valve check a laila ka valve a i ʻole ka valve butterfly
Pōmaikaʻi: hiki iā ia ke pale i ka valve check, ʻoi aku hoʻi i nā pāpaʻi like.Ke hoʻomaka ʻole ka pauma a hoʻomaka ka pauma ʻē aʻe, lawe ʻia ka ikaika hopena e ka valve puka a i ʻole ka valve butterfly.
Nā pōʻino: ʻo wai ka mea nāna e pale i ka ʻīpuka puka a i ʻole ka pahu nānā?Aia kekahi hihia ua haki ka pā kīpē o ka valve butterfly.
2. E hoʻokomo i ka valve puka a i ʻole ka valve butterfly ma mua o ka nānā ʻana i ka valve
Pōmaikaʻi: hiki iā ia ke pale i ka valve butterfly a i ʻole ka valve puka, a ʻo ka ikaika o ka hopena e lawe ʻia e ka pahu pahu
Nā pōʻino: ʻo wai ka mea e pale i ka valve check?Wehe ʻia a pani ʻia ka valve check e ka ʻokoʻa kaomi.Inā kiʻekiʻe ke kaomi poʻomanaʻo, e pani ʻia a wehe ʻia ke kaomi pahū.Inā ʻaʻole paʻa ka kahe i hoʻohana ʻia, e wehe ʻia a pani pinepine ʻia ka valve check, e pili ana i ke ola lawelawe o ka valve check.
