Kūkākūkā e pili ana i ka hoʻohana ʻana i nā kīwaha hōʻailona no nā kiwi hoʻokele wai ahi ma nā hale kiʻekiʻe

Abstract: ʻO ka manaʻo kiʻekiʻe kiʻekiʻe o ke kūkulu ʻana i ke ahi hydrant control valve me ka hoʻohana ʻana i ke kūkākūkā valve hōʻailona
Hua'ōlelo kiʻekiʻe: hale kiʻekiʻe kiʻekiʻe ke ahi hydrant control valve signal valve
Wahi a nā ʻōlelo o "Code for Fire Prevention Design of High-rise Civil Buildings", i loko o ka ʻōnaehana hoʻoheheʻe ahi i loko, pono e hoʻokaʻawale ʻia ka pipeline wai i nā ʻāpana **, a ʻo ka valve e loaʻa nā hōʻailona wehe a kokoke. ʻAʻole emi ka nui o nā paipu wai wai ma mua o hoʻokahi i ka wā e lawelawe ʻia ai ka paipu.
Me ka hoʻomohala ʻana o ka hale hoʻolālā hou, pono e hūnā ʻia ke kūkulu ʻana i nā pipelines like ʻole no ka makemake nani e like me ka mea hiki ke hoʻonani, no laila, pālahalaha nā paipu hydrant i loko o ke kaupaku, paipu paipu, akā he pilikia kēia, ʻo ia hoʻi ka mana o ka valve. ʻAʻole hiki i ka paipu hydrant ahi hāmama ke loaʻa ka nānā ʻana, no ka hoʻohana ʻana i ka hydrant ahi hiki ke hoʻohana maʻamau. Eia kekahi mau laʻana:
ʻO ka papahana o "State Grid Control Center of Ministry of Electric Power" e uhi ana i kahi kūkulu hale ʻoi aku ma mua o 50,000 square meters, me ʻekolu papa lalo a me 27 papa ma luna o ka honua. ʻO ke kiʻekiʻe o ka hale ma luna o 110 mika. He hale hoʻonaʻauao piha ia e hoʻohui ana i ke kauoha hana a me ka hoʻouna ʻana, ke keʻena a me nā hana o ka hālāwai kūkā, a ʻaʻole kakaikahi kona kiʻekiʻe o ka automation ma Kina. I ka hoʻolālāʻana i ka'ōnaehana hoʻoheheʻe waina, ua hoʻohana au i nā kīpili hōʻailona i mua o nā hōʻailona holowai a pau, no laila hiki ke hōʻikeʻia ke kūlana o ka pūnaewele i ke kikowaena ahi, a hiki ke loaʻa nā pilikia ma kahiʻike maopopo. Eia kekahi, ʻo ka mālama ʻana i ke kiʻekiʻe o ka wai o ke ola a me ke kaua ʻana i ke ahi, a me ka hoʻomaka ʻana a me ka pau ʻana o ka pauma ahi e nānā pono ʻia. ʻO ka valve control wale nō o ka ʻōnaehana hydrant ahi e like me ka kikoʻī o ka valve maʻamau, loaʻa iā ia nā hōʻailona o ka wehe ʻana a me ka pani ʻana, akā ʻaʻole hiki ke hōʻike ʻia i ke kikowaena hoʻomalu ahi, ʻo ia hoʻi, aia kēia mau valve i loko o ka pūnāwai. a me ke kaupaku no nā pono aesthetic, ʻaʻole hiki i ka maikaʻi o nā limahana o kēia manawa ke hōʻoia i ka hilinaʻi o ka ʻōnaehana. I ke ahi pale nenoaiu i ke kaʻina hana o ka 'ae, oiai ke alakai o ka 'oihana 'oihana keʻena keʻena, kūkulu 'ana a me ka manao na'emu mea loa seriously, ua hana i ka deployment a me ka rectification mua, maikaʻi rehearsed, akā, i ke kaʻina hana o ke ahi oihana luna maoli maoli. ka ʻae ʻana, akā aia kahi pilikia, aia kahi mea hoʻoheheʻe ahi ma ka standpipe ʻaʻole hiki ke hoʻokuʻu i waho o ka wai, a ʻo nā mea ʻehā ʻē aʻe he mea maʻamau, ʻAʻole hiki iā mākou ke loaʻa kahi pilikia ma ke kikowaena mālama ahi. Ma hope o ka nānā ʻana, ua ʻike ʻia ua pani ʻia nā pahu hoʻokele ma nā ʻaoʻao ʻelua o ka riser ma muli o ka mālama ʻana, ʻaʻole i wehe nā limahana i nā kiwi ma hope o ka mālama ʻana, no laila ʻaʻole e wai ka wai ahi.
Manaʻo wau, inā pili nui nā mea a pau i kēia ʻano pilikia, a ʻo ka mea maʻamau i ka maʻi lolo maʻalahi ʻaʻole ʻike i ke ʻano o ka pilikia. Pili kēia inā ʻo ka ʻōnaehana hydrant ahi ke kī i ka hoʻohana pono ʻana i nā pilikia, a pale i kēia kūlana e ʻike ʻia * * ala hilinaʻi ʻo ke ahi hydrant system control valves ua hoʻonoho ʻia i loko o ka pahu hōʻailona, ​​a wehe ʻia ka valve e hōʻike i ke kikowaena. o ka hoomalu ana i ke ahi, no ka nana ana o na kanaka hooponopono, oiai ua pii ke kumukuai, aka, o ka lakio o ka hookomo ana i ka pauku ahi a pau, he uuku loa, a hiki ke hana i ka holo a pau o ke ahi hydrant system palekana ** hoʻomaikaʻi, i Manaʻo wau he mea kūpono ke kālā.
ʻO ka pahu hoʻomalu e like me ka hoʻokaʻawale ʻana o nā hiʻohiʻona hoʻolālā (1) ma o ka pahu hoʻomalu noho hoʻokahi: ʻo ka valve * * hoʻohana nui ʻia, he leak kekahi  ʻae ʻia ke kaomi ʻokoʻa kekahi  kahe paʻakikī a me nā hiʻohiʻona o ka hale maʻalahi, no laila ua kūpono no ka ʻO ka leaka paʻa, ʻokoʻa liʻiliʻi o ka hana maʻemaʻe, akā hiki ke hoʻohana ʻia nā kikoʻī liʻiliʻi o ka nui nominal valve (DN (2) pololei ma waena o ʻelua mau noho mana valve: ʻokoʻa i ka valve hoʻokele hoʻokahi noho hoʻokahi, loaʻa iā ia nā hiʻohiʻona o ka leakage nui a me ka ʻokoʻa ʻokoʻa i ʻae ʻia, no laila ua kūpono ia no nā manawa media maʻemaʻe me nā koi leakage lax a me ka nui. ʻokoʻa kaomi hana. Pono e noʻonoʻo inā kūpono ka nui o ka leakage o ka valve i nā koi kaʻina hana i ke koho ʻana i ka valve.
(3) Sleeve valve: hoʻokaʻawale ʻia ka valve lima i ka sila hoʻokahi a me ka sila pālua ʻelua mau hale, ua like ka mea mua me ka valve noho hoʻokahi, kūpono no nā manawa valve noho hoʻokahi. ʻO ka hope e like me ka valve noho ʻelua, kūpono no nā manawa valve noho ʻelua. Loaʻa nā hiʻohiʻona o ke kūpaʻa maikaʻi, ka hoʻouka ʻana a me ka wehe ʻana, akā ʻo ke kumukūʻai ʻo 50% ~ 200% kiʻekiʻe ma mua o ka valve noho hoʻokahi, ka valve noho pālua, pono pū kekahi gasket winding kūikawā. ʻO ka valve lima ka mea haʻahaʻa loa i ka hoʻokahi - noho valve, pālua - noho valve noi o ka valve.
(4) ʻO ka valve Angle, ua like ke ʻano throttle me ka valve noho hoʻokahi, akā maʻalahi ke kahe o ke kino, pili i ka leak e pono ai i kekahi mau manawa maʻemaʻe maʻemaʻe a me nā koi o ke kaomi ʻokoʻa ʻo ka paipu rectangular.
(5) ʻekolu ala ala: he 3 mau ala, hiki ke hoʻololi i ka valve noho hoʻokahi pololei, hoʻohana ʻia no ka shunt a me ka hui ʻana a me nā kahe ʻelua, ʻaʻole ʻoi aku ka ʻokoʻa o ka mahana ma mua o 150 ℃. I ka DN≤80 mm, hiki ke hoʻohana i ka valve confluence no nā manawa shunt.
(6) Diaphragm valve: ke ala kahe maʻalahi, ʻo ka diaphragm kekahi mau hana kūʻē i ka corrosion, kūpono no ka mea maʻemaʻe ʻole, ʻelua mau manawa ʻoki ʻia.
Butterfly valve (7): ua like ia me ka hoʻohana ʻana i ka pauku no ke kino, a ua like ke kino me ka noho, no laila maikaʻi ka hana "hoʻomaʻemaʻe ponoʻī", ʻoi aku ka nui o ke kaumaha. He kūpono no ka mea maʻemaʻe maʻemaʻe a me ke anawaena nui, kahe nui, ʻokoʻa kaomi nui. I ka Dn > 300 mm, e hoʻopau pinepine ʻia e ka valve butterfly.
(8) Kiwi pōʻalo: ʻO ke ʻano kīpē pōleʻa i ka wā e hāmama pono ai no ka pahu hāmama, ʻoi aku ka maikaʻi o ka hana "hoʻomaʻemaʻe ponoʻī", kūpono no ka maʻemaʻe maʻemaʻe, fiber medium ʻelua mau manawa ʻoki. ʻO ka valve BALL "V" he like me ka pākēneka hoʻololi i nā hiʻohiʻona, kūpono no ka maʻemaʻe, me ka media fiber, hiki ke hoʻololi i nā manawa mana nui. ʻOi aku ke kumukūʻai o nā kiwi kinipōpō.
(9) Eccentric rotary valve: ʻo ka valve ma waena o ka valve butterfly a me ka ball valve, maikaʻi ka hana "hoʻomaʻemaʻe iā ia iho", maikaʻi ka hoʻoponopono ʻana i ka hana, hiki ke ʻoki ʻia, no laila ua kūpono ia no ka maʻemaʻe maʻemaʻe, nā koi leakage o nā manawa hoʻoponopono liʻiliʻi, akā, ʻoi aku ka pipiʻi o ke kumukūʻai o ka valve.
ʻO ka 6 mua o kēia mau huahana 9 he mau pahu hoʻomalu stroke pololei, a ʻo ka hope 3 he mau pahu mana stroke angular. E like me ka hoʻohana ʻana i ka valve control, pono e wehewehe i ko lākou mau hiʻohiʻona a me nā mea e pono ai ka nānā. ʻO nā ʻano huahana like ʻole a pau, hoʻomaikaʻi ʻia nā huahana i kēia mau ʻano huahana 9, maʻalahi ke hoʻomaopopo i nā ʻano huahana 9 e haku i ka noi o nā huahana ʻē aʻe.
