ʻIke kumu o ka valve puka

ʻīpuka pukaʻo ia ka huahana o ka hoʻololi ʻoihana. ʻOiai ua lōʻihi ka lōʻihi o kekahi mau hoʻolālā valve, e like me nā valves globe a me nā plug valves, ua noho nā valve valves i kahi kūlana koʻikoʻi i ka ʻoihana no nā makahiki he mau makahiki, a i kēia manawa wale nō lākou i hāʻawi aku ai i kahi māhele mākeke nui i ka pōlele pōlele a me nā hoʻolālā ʻana o ka valve butterfly. .

ʻO ka ʻokoʻa ma waena o ka ʻīpuka ʻīpuka a me ke kinipōpō pōleʻa, ka valve plug a me ka valve butterfly, ʻo ia ka mea pani, i kapa ʻia ka disc, gate or occluder, piʻi ma lalo o ke kumu valve a spindle, haʻalele i ke ala wai a komo i ka piko o ka valve, kapa ʻia ʻo bonnet. a kaʻa ʻana i ka milo a i ʻole ka milo i nā huli he nui. ʻO kēia mau pahu e hāmama ana i ka neʻe laina, ʻike ʻia hoʻi ʻo ia he multi turn a i ʻole linear valves, ʻaʻole like me nā valve turn quarters, nona ke kumu e hoʻololi ai i 90 degere a ʻaʻole piʻi maʻamau.

Loaʻa nā ʻīpuka puka ma nā ʻano mea like ʻole a me nā helu kaomi. Loaʻa lākou i ka nui mai ka NPS i kūpono i kou lima ½ ʻīniha a hiki i ke kaʻa nui NPS 144 iniha. Loaʻa nā kiwi puka i nā hoʻoheheʻe, forgings, a i ʻole nā ​​​​mea hana i hana ʻia e ke kuʻi ʻana, ʻoiai ʻo ka hoʻolālā hoʻoheheʻe ʻana e lanakila.

ʻO kekahi o nā hiʻohiʻona i makemake nui ʻia o nā ʻīpuka ʻīpuka, ʻo ia ka hiki ke wehe piha ʻia me ke keʻakeʻa liʻiliʻi a i ʻole ka hakakā ʻana i nā lua kahe. ʻO ke kūpaʻa kahe i hāʻawi ʻia e ka ʻīpuka hāmama e like me ka ʻāpana o ka paipu me ka nui o ke awa. No laila, noʻonoʻo nui ʻia nā ʻīpuka puka no ka hoʻopaʻa ʻana a i ʻole i nā noi. I kekahi mau inoa valve, ua kapa ʻia nā ʻīpuka ʻīpuka he ʻāpau honua.

ʻAʻole kūpono nā ʻīpuka puka no ka hoʻoponopono ʻana i ke kahe ʻana a i ʻole ka hana ʻana ma nā ʻaoʻao ʻē aʻe ma waho o ka hāmama a paʻa piha. Hiki ke hoʻopōʻino i ka pā valve a i ʻole ke apo noho valve, no ka mea, i loko o kahi ʻāpana hāmama e hoʻoulu ai i ka haunaele, e hui pū nā ʻili o ka noho valve me kekahi.

ʻAno kīpē puka

Mai waho mai, ʻano like ka nui o nā ʻīpuka puka. Eia naʻe, nui nā ʻano hoʻolālā like ʻole. ʻO ka hapa nui o nā ʻīpuka ʻīpuka he kino a me ka pāpale, aia kahi mea pani i kapa ʻia he diski a i ʻole puka. Hoʻopili ʻia ka mea pani i ke kumu e hele ana ma ka pāpale a hope i ka huila lima a i ʻole ka hoʻokele ʻē aʻe e hoʻohana ai i ke kumu. Hoʻomalu ʻia ke kaomi a puni ke kumu valve e ka hoʻopili ʻia ʻana i loko o ka ʻāpana packing a i ʻole ke keʻena.

ʻO ka neʻe ʻana o ka pā kīpē puka ma ke kumu valve e hoʻoholo ai inā piʻi a wili paha ke kumu valve i loko o ka pā valve i ka wā e wehe ai. Ho'ākāka pū kēia pane i nā ʻano kumu ʻelua/disc no nā kiwi puka: ke kumu piʻi a i ʻole ke kumu piʻi ʻole (NRS). ʻO ka lāʻau piʻi ke ʻano hoʻolālā kaulana loa i ka mākeke ʻoihana, ʻoiai ʻo ke kumu piʻi ʻole ua makemake nui ʻia e ka ʻoihana wai a me ka pipeline. Ke hoʻohana nei kekahi mau moku moku e hoʻohana mau ana i nā ʻīpuka puka a loaʻa nā wahi liʻiliʻi i ke ʻano NRS.

ʻO ka hoʻolālā maʻamau maʻamau ma nā ʻūhā ʻoihana ʻo ke kaula waho a me ka ʻauamo (OS&Y). ʻOi aku ka maikaʻi o ka hoʻolālā OS&Y no nā kaiapuni corrosive no ka mea aia nā kaula ma waho o ka wahi seal fluid. He ʻokoʻa ia mai nā ʻano hoʻolālā ʻē aʻe i ka pili ʻana o ka huila lima i ka puʻu ma luna o ka ʻauamo, ʻaʻole i ke kumu ponoʻī, i ʻole e piʻi ka huila lima i ka wā e wehe ai ka pahu.

ʻO ka māhele makeke ʻīpuka puka

ʻOiai i loko o nā makahiki he 50 i hala iho nei, ua paʻa ka ʻāpana nui o nā kīwaha rotary kihi ʻākau i ka mākeke valve puka, ke hilinaʻi nui nei kekahi mau ʻoihana iā lākou, me ka ʻoihana ʻaila a me ke kinoea. ʻOiai ua holomua nā kiwi pōpō i nā paipu kinoea maoli, ʻo ka ʻaila ʻaila a i ʻole nā ​​pipeline wai ka wahi o nā ʻīpuka noho like.

I ka hihia o nā nui nui, ʻo nā kīwaha puka ke koho nui no ka hapa nui o nā noi i ka ʻoihana hoʻomaʻemaʻe. ʻO ka paʻa o ka hoʻolālā a me ka nui o ke kumukūʻai o ka ʻona (me ka hoʻokele waiwai o ka mālama ʻana) nā mea i makemake ʻia o kēia hoʻolālā kuʻuna.

Ma ke ʻano o ka noi, nui nā kaʻina hana hoʻomaʻemaʻe e hoʻohana i nā mahana i ʻoi aku ka kiʻekiʻe ma mua o ka wela o ka hana palekana o Teflon, ʻo ia ka mea noho nui no nā kiwi pōpō lana. Ke hoʻomaka nei ka hoʻohana hou ʻana o nā kiwi lele lele a me nā kiwi pōpō metala i hoʻopaʻa ʻia i ka hoʻohana ʻana i nā noi hoʻomaʻemaʻe, ʻoiai ʻoi aku ka nui o kā lākou kumukūʻai o ka ʻona ma mua o nā kiwi puka.

ʻO ka ʻoihana kanu wai ka mea i hoʻomalu ʻia e nā kiwi puka hao. ʻOiai i loko o nā noi i kanu ʻia, ua maʻalahi lākou a paʻa.

Hoʻohana ka ʻoihana mananā kīpē puka haono nā noi e pili ana i nā kaomi kiʻekiʻe loa a me nā wela kiʻekiʻe loa. ʻOiai ua loaʻa kekahi mau kīwī poʻomanaʻo Y-type hou a me nā kiwi pōpō noho metala i hoʻolālā ʻia no ka lawelawe ʻana i ka lawelawe ʻana i loko o ka hale mana, makemake mau ʻia nā kiwi puka e nā mea hoʻolālā a me nā mea hana.
