Hoʻolālā ʻo Flowrox i kahi hoʻolālā hou no ka ʻīpuka slurry knife nui. Ua ʻōlelo ʻia ua hoʻopau ʻia ka pono o ka hale kiaʻi cylinder a hoʻonohonoho hou i ʻelua mau pahu hana i kēlā me kēia ʻaoʻao o ka valve.
Loaʻa pinepine ʻia nā kīwaha ʻīpuka pahi ma nā concentrators, nā huelo a me ka lawe ʻana i ka lepo, a me nā hana leaching.
Wahi a ka hui Finnish, ʻo ka hoʻolālā hale kiaʻi o nā mea hana kuʻuna maʻamau e kūpono i nā ʻīpuka puka blade, akā aia wale nō i kahi nui. "ʻO ka nui o ka DN, ʻoi aku ka kiʻekiʻe o ka valve," wahi a Flowrox.
"Inā makemake mākou i kahi valve DN 1200," wahi a ka hui. "Ke hoʻohana nei i kahi hoʻolālā hale kiaʻi, ʻo ia ka mea e kiʻekiʻe loa ka valve i ke kūlana ākea: 5.6 m! ʻO ke kiʻekiʻe kiʻekiʻe loa ke ʻano o ke kikowaena kiʻekiʻe o ka umekaumaha. ʻOi aku ka paʻakikī o ka hana ʻana i ka ʻīpuka ʻīpuka pahi, ʻoi aku ka paʻa i ka wā o ka hui ʻana, a ʻoi aku ka paʻakikī o Itos e mālama. I nā huaʻōlelo ʻē aʻe, ʻaʻole palekana kēlā. "
Ua hoʻopau ka hoʻolālā i ka hale kiaʻi cylinder o ka ʻīpuka puka pahi a ua hoʻonohonoho hou i nā cylinders actuator ʻelua i kēlā me kēia ʻaoʻao o ka valve, wahi a ia. Ma muli o ka laʻana ma luna, ua ana ʻo Flowrox DN 1200 knife gate valve i kēia manawa he 3.6 m ma ke kūlana hāmama loa: ʻelua mau mika ma lalo o ka hoʻolālā hale kiaʻi.
Wahi a Flowrox, ʻo ke kiʻekiʻe o ka valve haʻahaʻa, ʻo ia hoʻi ke kikowaena haʻahaʻa o ka umekaumaha. ʻO kēia ka mea i ʻoi aku ka paʻa a me ka palekana o ka valve puka pahi.
"ʻAʻole wale ka maʻalahi o ka hoʻouka ʻana, pono nō hoʻi ka liʻiliʻi o ka wahi ma luna o ka valve," wahi a ka hui. “Aia nā wahi mālama mālama a pau ma lalo o 2 m mai ka honua aku, no laila hiki ke maʻalahi. Pēlā nō, hiki ke hana ʻia nā pili ʻē aʻe a pau ma ka honua a i ʻole mai ka honua ma mua o ka lewa.
I ka hihia o kahi hoʻolālā hale kiaʻi, pono e hana ʻia ka hana mālama ma kahi mamao o 3-4 m mai ka honua, e lawe mai ana i nā pilikia palekana, koi i nā kaʻina hana palekana a hoʻopau i ka manawa hou. ”
ʻO ka maʻamau, hana ʻia ke kino valve i ʻelua ʻāpana a hoʻopaʻa pū ʻia, e hoʻoulu ai i ka leakage a me ka nui o ka hana bolting i ka wā mālama.
Ua hoʻolei ʻia ke kino valve o ka ʻīpuka kīwaha Flowrox slurry knife i hoʻokahi ʻāpana, ʻo ia hoʻi, ʻaʻohe pilikia o ka leakage mai ke kino valve. ʻO ia ka hopena i kahi hoʻolālā maʻalahi, ʻoi aku ka ikaika a me nā ʻāpana liʻiliʻi, ʻo ia hoʻi ka mālama ʻana i ka waihona ʻāpana ʻāpana a me ka manawa mālama.
Ua hoʻopau ka hui: "ʻOi aku ka paʻa o nā kīwaha ʻo Flowrox slurry knife, maʻalahi ke hoʻokomo a maʻalahi hoʻi e mālama. Hiki i kēia mau valve DN 900-DN 1500 ke hoʻopaʻa i nā kaomi mai ka 10 bar a me ka haʻahaʻa e like me 4 bar, ma muli o ka nui.
