E nānā i ka valve, i ʻike ʻia ʻoone way check valve.ʻO kāna hana nui ka pale ʻana i ka backflow o ka medium a pale i ka hana palekana o nā lako a me nā ʻōnaehana pipeline.ʻO nā kiwi waihoʻohana nui ʻia i ka ʻaila, ʻoihana kemika, mālama wai, mana uila, metallurgy a me nā ʻano ʻē aʻe.

Nui nā ʻano o nā ʻāpana loiloi, e like me ke ʻano ʻokoʻa a me ka loina hana, hiki ke hoʻokaʻawale ʻia i ke ʻano hāpai, ʻano kowali,lele lele, ʻano kinipōpō a pēlā aku.Ma waena o lākou, kahoʻokiʻekiʻe kiwiʻo ia ka mea maʻamau, nona ka pā valve i loko e hiki ke hāpai ʻia, a i ka wā e kahe ai ke kikowaena mai ke komo ʻana a i ka puka, ua wehe ʻia ka pā valve;Ke holo ka mea waena ma ka ʻaoʻao ʻaoʻao, ua pani ʻia ka diski e pale i ke kahe hope.

I mea e hōʻoia ai i ka hana maʻamau o kakiwikā kuhiliʻolea hoʻonui i kona ola lawelawe, he mea nui ka mālama ʻana i kēlā me kēia lā.Eia kekahi mau ʻike mālama mālama i kēlā me kēia lā o nā pahu pahu:

1. Nānā mau

E nānā mau i ke ʻano o ka pahu hoʻopaʻa no ka ʻike inā he mau māwae, deformation, corrosion a me nā mea ʻē aʻe.I ka manawa like, e nānā i ke sila o ka disc a me ka noho no ka hōʻoia ʻana ʻaʻohe leakage.

2. Hoomaemae

E hoʻomaʻemaʻe mau i loko a me waho o ka pahu pahu no ka wehe ʻana i ka lepo a me nā haumia.I ka hoʻomaʻemaʻe ʻana, pono e hoʻohana ʻia ka mea hoʻomaʻemaʻe kūʻokoʻa e pale i ka hoʻohana ʻana i nā mea corrosive e like me ka waikawa ikaika a me ka alkali.

3. Hoʻololi i nā ʻāpana i hōʻino ʻia

Inā ʻike ʻia ka pōʻino a i ʻole ʻino ʻia ka disc valve, ka noho a me nā ʻāpana ʻē aʻe o ka valve check, pono e hoʻololi ʻia i ka manawa.E hoʻololi me nā kikoʻī like a me nā hiʻohiʻona o nā ʻāpana kumu e hōʻoia i ka hopena ʻole o ka hana o ka valve.

4.Lubrication

No kekahi mau pahu hoʻomaʻamaʻa pono e lubricated, pono e hoʻohui pinepine ʻia ka nui o ka aila lubricating a i ʻole ka momona e mālama pono i ke kumu a me ka noho.

5.Anti-corrosion lapaʻau

No ke kiwi hoʻopaʻa laina i hoʻohana ʻia i loko o kahi pōʻino, pono e lawe ʻia nā ana anti-corrosion e like me ka uhi ʻana i ka papa anti-corrosion a me ke koho ʻana i nā mea kū i ka corrosion.

Ma o nā hana mālama mālama i kēlā me kēia lā, hiki iā ʻoe ke hōʻoia i ka hana maʻamau o ka valve check a hoʻolōʻihi i ke ola lawelawe, a hāʻawi i kahi hōʻoia ikaika no ka palekana o nā mea hana a me nā ʻōnaehana pipeline.
