ʻO ka valve nānā, i ʻike ʻia hoʻikiwikā nānā ala hoʻokahiʻO kāna hana nui, ʻo ia ke pale ʻana i ke kahe hope o ka medium a pale i ka hana palekana o nā lako a me ka ʻōnaehana pipeline.Nā kiwikā nānā waiHoʻohana nui ʻia i ka ʻaila, ka ʻoihana kemika, ka mālama wai, ka mana uila, ka metallurgy a me nā kahua ʻē aʻe.

Nui nā ʻano o nā kiwikā hōʻoia, e like me ke ʻano like ʻole a me ke kumu hana, hiki ke hoʻokaʻawale ʻia i ke ʻano hāpai, ke ʻano lele,kiwikā nānā pulelehua, ʻano pōpō a pēlā aku. I waena o lākou, ʻo kakiwikā hōʻoia hāpaiʻo ia ka mea maʻamau, nona kahi ʻaoʻao valve kūloko e hiki ke hāpai ʻia, a i ka wā e kahe ai ka medium mai ke komo ʻana a i ka puka ʻana, ua wehe ʻia ka ʻaoʻao valve; Ke kahe ka medium i ke kuhikuhi ʻē aʻe, ua pani ʻia ka disc e pale i ke kahe hou ʻana.

I mea e hōʻoia ai i ka hana maʻamau okiwikā hōʻoia kila kilaa hoʻolōʻihi i kona ola lawelawe, he mea nui loa ka mālama ʻana i kēlā me kēia lā. Eia kekahi mau ʻike mālama i kēlā me kēia lā o nā kiwikā nānā:

1. Nānā mau

E nānā pinepine i ke ʻano o ka valve nānā e ʻike inā he mau māwae, deformation, corrosion a me nā hanana ʻē aʻe. I ka manawa like, e nānā i ke sila o ka disc a me ka noho e hōʻoia i ʻaʻohe leaka.

2. Hoʻomaʻemaʻe

E hoʻomaʻemaʻe pinepine i loko a i waho o ka valve nānā e wehe i ka lepo a me nā mea haumia. I ka hoʻomaʻemaʻe ʻana, pono e hoʻohana i ka mea hoʻomaʻemaʻe kūlike ʻole e pale aku i ka hoʻohana ʻana i nā mea ʻino e like me ka waikawa ikaika a me ka alkali.

3. E hoʻololi i nā ʻāpana i hōʻino ʻia

Inā ʻike ʻia ua hōʻino ʻia a ua ʻaʻahu nui ʻia paha ka disc valve, ka noho a me nā ʻāpana ʻē aʻe o ka valve check, pono e hoʻololi ʻia i ka manawa kūpono. E hoʻololi me nā kikoʻī like a me nā hiʻohiʻona o nā ʻāpana kumu e hōʻoia ʻaʻole e hoʻopilikia ʻia ka hana o ka valve.

4.Lubrication

No kekahi mau kiwikā nānā e pono ai ke lubricate ʻia, pono e hoʻohui pinepine ʻia kahi nui kūpono o ka ʻaila lubricating a i ʻole ka grease e mālama i ka lubrication maikaʻi ʻia o ke kumu a me ka noho.

5. Ka mālama ʻana i ka palaho

No ka valve hōʻoia laina i hoʻohana ʻia i loko o kahi ʻano corrosive, pono e hana ʻia nā hana anti-corrosion kūpono, e like me ke uhi ʻana i ka papa anti-corrosion a me ke koho ʻana i nā mea kūpaʻa i ka corrosion.

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