1. Nā waiwai ikaika

Ka hana ikaika o kaPahu Pahu keleawee pili ana i ka hiki o ka pahu keleawe ke pale aku i ke kaomi o ka waena.ʻO nā pahu keleawe he mau huahana mechanical e pili ana i ke kaomi o loko, no laila pono lākou e lawa ka ikaika a me ka rigidity e hōʻoia i ka hoʻohana lōʻihi me ka ʻole o ka haki ʻana a me ka deformation.

2. Hana sila

Ka hana hoailona o kaPahu Pahu keleawee pili ana i ka hiki o kēlā me kēia ʻāpana hoʻopaʻa ʻana o ka valve keleawe e pale ai i ka leakage o ka mea waena, he mea koʻikoʻi ka hana ʻenehana o ka valve keleawe.ʻEkolu mau ʻāpana hoʻopaʻa ʻana o ka valve keleawe: ʻo ka pilina ma waena o nā ʻāpana wehe a pani ʻia a me nā ʻāpana hoʻopaʻa ʻelua o ka noho valve;kahi kūpono ma waena o ka hoʻopili ʻana a me ka pahu valve a me ka pahu meaʻai;ka pilina ma waena o ke kino valve a me ka pāpale.ʻO ka leakage ma ka ʻaoʻao mua i kapa ʻia he leakage kūloko, i kapa ʻia ʻo lax closure, e hoʻopilikia i ka hiki o ka valve keleawe e ʻoki i ka waena.No nā kiwi pani, ʻaʻole ʻae ʻia ka leaka o loko.ʻO ka leakage ma nā wahi ʻelua hope i kapa ʻia ʻo ka leakage waho, ʻo ia hoʻi, ka leaka o ka waena mai loko o ka valve a i waho o ka valve.ʻO ka leaka o waho e lilo i mea waiwai, hoʻohaumia i ke kaiapuni, a hiki i nā ulia i nā hihia koʻikoʻi.No ka mea pahū, pahū, ʻona a i ʻole radioactive media, ʻaʻole ʻae ʻia ka leakage, no laila pono e loaʻa i nā kiwi keleawe ka hana hoʻopaʻa paʻa.

3. Mea kahe

Ma hope o ke kahe ʻana o ka mea ma waena o ka valve keleawe, e loaʻa kahi poho puʻe (ʻo ia hoʻi, ka ʻokoʻa o ke kaomi ma mua a ma hope o ka valve keleawe), ʻo ia hoʻi, he kūʻē ʻia ka valve keleawe i ke kahe ʻana o ka waena, a ʻo ka waena. e hoʻopau i kahi nui o ka ikehu e lanakila ai i ke kū'ē o ka valve keleawe.Ke noʻonoʻo nei i ka mālama ʻana i ka ikehu, i ka hoʻolālā ʻana a me ka hana ʻana i nā kiwi keleawe, pono e hoʻemi ʻia ke kūʻē ʻana o nā kīwaha keleawe i ke kahe kahe e like me ka hiki.

4. Wehe a pani ikaika a me ka wehe a me ka pani torque

ʻO ka wehe a pani ʻana i ka ikaika a me ka wehe ʻana a me ka pani pani e pili ana i ka ikaika a i ʻole ka torque e pono e hana ʻia e ka valve keleawe e wehe a pani paha.I ka wā e pani ai i ka valve keleawe, pono e hana i kekahi lākiō puʻe sealing ma waena o ka wehe a me nā ʻāpana pani a me nā ʻāpana hoʻopaʻa ʻelua o ka noho lauoho, a i ka manawa like, pono e lanakila i ka ʻokoʻa ma waena o ke kumu valve a. ka paʻi ʻana, ma waena o ke kumu valve a me ke kaula o ka nut, a me ke kākoʻo ma ka hope o ke kumu valve.a me nā ʻāpana friction ʻē aʻe, no laila pono e hoʻopili ʻia kahi mana pani a me ka torque pani.I ka wā o ka wehe ʻana a me ka pani ʻana o ka valve keleawe, ʻo ka wehe ʻana a me ka pani ʻana i ka ikaika a me ka wehe ʻana a me ka pani ʻana o ka torque hoʻololi, a ʻo ka waiwai nui loa i ka manawa hope o ka pani ʻana.a i ʻole ka manawa mua o ka wehe ʻana.I ka hoʻolālā ʻana a me ka hana ʻana i nā valve keleawe, pono e hoʻoikaika ʻia e hōʻemi i ko lākou pani pani a me ka manawa pani.

5. Wehe a pani ʻana i ka wikiwiki

Hōʻike ʻia ka wikiwiki o ka wehe ʻana a me ka pani ʻana e ka manawa i koi ʻia no ka valve keleawe e hoʻopau ai i kahi hana wehe a pani ʻana paha.ʻO ka mea maʻamau, ʻaʻohe koi koʻikoʻi no ka wehe ʻana a me ka wikiwiki o ka pani ʻana o nā valve keleawe, akā aia kekahi mau kūlana hana i nā koi kūikawā no ka wehe a me ka wikiwiki pani.Pono kekahi e wehe wikiwiki a pani paha i mea e pale ai i nā pōʻino, a koi kekahi i ka pani lohi e pale i ka hama wai, a me nā mea ʻē aʻe, pono e noʻonoʻo ʻia ke koho ʻana i ke ʻano o ka valve keleawe.

6. Ka naʻau hana a me ka hilinaʻi

E pili ana kēia i ka naʻau o ka valve keleawe i ka hoʻololi ʻana o nā ʻāpana waena a me ka pane e pili ana.No nā valve keleawe e like me throttle valves, pressure reduce valves, a me regulating valves i hoʻohana ʻia no ka hoʻoponopono ʻana i nā palena waena, a me nā valve keleawe me nā hana kikoʻī e like me nā valves palekana a me nā pahele mahu, ʻo ko lākou naʻau hana a me ka hilinaʻi he mau hōʻailona hana ʻenehana nui.

7. Ke ola lawelawe

Hōʻike ia i ka lōʻihi o ka valve keleawe, he kuhikuhi hana koʻikoʻi o ka valve keleawe, a he waiwai waiwai nui.Hōʻike pinepineʻia e ka helu o nā manawa o ka weheʻana a me ka paniʻana e hiki ai ke hōʻoia i nā koi o ka sila, a hiki ke hōʻikeʻia e ka manawa hoʻohana.
