I kēia manawa, ua hoʻopaʻa ʻia ʻelua mau DN2000 uilanā kiwikā maka anianimai kā mākou hale hana ua hoʻopili ʻia a hoʻomaka i kahi huakaʻi i Rusia. ʻO kēia halihali koʻikoʻi e hōʻailona ana i kahi hoʻonui holomua o kā mākou huahana ma ka mākeke honua.

Ma ke ʻano he mea hoʻomalu wai koʻikoʻi, uilakiwikā maka aniani pani ʻiaHe kumu hana kū hoʻokahi ko ia. Hoʻokele ia i ka papa valve e neʻe ma o kahi mea uila, e hoʻokō ana i ka wehe ʻana a me ka pani ʻana o ka pipeline. I ke kūlana pani ʻia, hiki i ka papa valve ke hoʻopaʻa pono i ka waha o ka paipu, e hana ana i kahi sila hilinaʻi a pale pono i ka liki ʻana o ka wai.

He nui nā pono o kēia ʻano kiwikā makapō. ʻO ka mea mua, ʻo kāna hana sila maikaʻi loa e hōʻoiaʻiʻo ana i ka ʻole o ka leakage ma lalo o nā kūlana hana like ʻole, e hāʻawi ana i ka hōʻoia palekana no ka hana ʻoihana. ʻO ka lua, he kūpono a wikiwiki ka hana uila, e ʻae ana i ka mana mamao a me ka hoʻomaikaʻi ʻana i ka pono o ka hana. Eia kekahi, hiki i ka hoʻolālā anawaena nui o DN2000 ke hoʻokō i nā koi o nā ʻōnaehana pipeline nui a kūpono no nā ʻano ʻoihana like ʻole.

I nā hana kūpono, hoʻohana nui ʻia ka valve aniani sila uila i nā ʻōnaehana pipeline i nā ʻoihana e like me ke kinoea, ke kinoea kūlohelohe, a me ka petroleum. Hiki iā ia ke ʻoki koke i nā wai i ka wā o ka mālama ʻana i ka pipeline, ka hoʻololi ʻana i nā lako, a me nā kūlana ʻē aʻe, e hōʻoiaʻiʻo ana i ka palekana kūkulu. I kēia manawa, hāʻawi pū kāna hana hilinaʻi i ke kākoʻo ikaika no ka hana mau o ka hana ʻoihana.

ʻO ka hoʻokuʻu aku ʻana o ʻelua mau valves papa makapō sila uila DN2000 i Rusia, ʻaʻole ia e hōʻike wale i kā mākou ʻenehana hana holomua a me nā huahana kiʻekiʻe, akā e hoʻohui pū i ka ikaika hou i ka laulima ma waena o Kina a me Rusia ma ke kahua ʻoihana. E hoʻomau mākou i ka hana ikaika, e hoʻomaikaʻi mau i ka maikaʻi o ka huahana a me ka pae ʻenehana, a e hāʻawi i nā huahana a me nā lawelawe maikaʻi aʻe no nā mea kūʻai aku kūloko a me nā haole.

Inā he mau koi valve kāu, e waiho i kahi leka ma lalo nei a e loaʻa iā ʻoe kahi pane loea i loko o 24 mau hola. E hāʻawi ʻo Jinbin Valve iā ʻoe i nā hoʻonā kūpono a ke kakali nei e hana pū me ʻoe!
