Valve kūloko leakage pae? ʻO ka hana ʻana o ka valve? Nā kikoʻī no ka pena kiwikā a me ka kaha ʻana

1, e hoʻoholo i ke ala leakage kūloko kūloko ma hope o ka pani ʻana o ka valve no 4-6 mau hola, e hoʻohana i ka thermometer infrared e ana i ke kumu (kokoke i ke kino valve) a i ʻole 150mm i lalo o ka wela metala kino valve, e like me ka nui ma mua o 70 ℃, ʻo ia. ʻike ʻia ʻo "leakage kūloko". Hoʻohana ʻia kēia ʻano hana i ka hapa nui o nā pahu leak kūloko. Akā i ka hana maoli, ua hālāwai mākou i nā hihia kūikawā1) ma muli o ke kūlana hoʻokomo o ka pipeline, aia kekahi mau valve ma mua a ma hope o ka haunaele o ka mahu wela kiʻekiʻe, e like me ka pili ʻana i ke kaomi o ke kahawai, ke kahawai o ka paipu jellyfish.
ʻO ka mea mua, ke kūlana hoʻoholo leakage valve
1, e hoʻoholo i ke ʻano leakage valve
Ma hope o 4-6 mau hola o ka pani ʻana o ka valve, e hoʻohana i ka thermometer infrared e ana i ka mahana metala ma ke kumu (kokoke i ke kino) a i ʻole 150mm i lalo o ke kino, inā ʻoi aku ka nui ma mua o 70 ° c, ua manaʻo ʻia ʻo ia he "leakage kūloko". Hoʻohana ʻia kēia ʻano hana i ka hapa nui o nā pahu leak kūloko.
Eia naʻe, i kā mākou hana hoʻomaʻamaʻa, ua hālāwai mākou i nā hihia kūikawā penei:
(1) Ma muli o ke kūlana hoʻonohonoho o ka pipeline, aia kekahi mau kiwi ma mua a ma hope o ka haunaele o ka mahu wela wela, e like me ka pili ʻana i kahi wai kaomi, pahele paipu jellyfish a i ʻole ka puka wai, ʻo kēia mau kiwi inā paʻa ka leakage, ka valve. ʻOi aku ka mahana o ke kumu ma mua o 70 ℃.
(2) E komo i ka puka pahele a i ʻole ka puka wai o ka pahele a me ka paipu jellyfish. Ke kokoke ke kūlana o ka valve i ka paipu haku, ʻoiai e kahe ana kekahi lālā lālā o ka pipeline, e piʻi ka mahana o nā kiwi ʻē aʻe i ʻoi aku ma mua o 70 ℃, e like me ka valve drain boiler, superheated steam drain, etc. No laila, pono e hana ʻia ka hoʻoholo ʻana i ka leaka o loko ma kēia mau ʻano ʻē aʻe, e like me ke ana ʻana i ka wela o ka pā puka puka a i ʻole ka mahanahana o ka puka puka mua e hoʻoholo ai i ka leaka o loko.
ʻElua, ʻo ka hana valve ka mea pono e nānā
1. No nā puka lima o ka wai hoʻoheheʻe wai o ka ʻōnaehana wela, pono e hoʻopaʻa hou ʻia lākou i ka hapalua hola ma hope o ka pau ʻana o ka hana e hoʻopau i ke āpau o ka valve i hoʻokumu ʻia e ka hoʻonui wela a me ka hoʻohaʻahaʻa anu.
2. No ka paipu wela me hoʻokahi a ʻelua mau puka, ʻo ke kaʻina hana o ka valve penei: wehe i ka puka i hoʻokahi manawa ma mua o ka wehe ʻana i ka puka ʻelua; I ka wā e pani ai, pono ʻoe e pani mua i ka puka ʻelua a pani hou i ka puka.
3, no ka hana ʻana o ka ʻīpuka puka, hiki ke pani paʻa ʻia a wehe ʻole ʻia, ʻaʻole e ʻae i ka hapalua wehe i ka hapalua pani pani, i mea e hōʻemi ai i ka pōʻino o ka pā.
ʻEkolu, pono ka nānā ʻana i ka hoʻokele valve
ʻO ka Unit 1, ma mua o ka hoʻomaka ʻana o kēlā me kēia uila, ka hoʻāʻo ʻana i ka valve pneumatic, ke kaʻina hoʻāʻo, pono e lilo i mea loea i ka nānā ʻana i ka valve a me ka neʻe ʻana o ka neʻe ʻana, e nānā i ke koʻokoʻo hoʻohui a me ka pine ʻaʻole e wehe, kūlou a hāʻule, e nānā i nā kuhikuhi o ka wehe ʻana o ka DCS a ʻo ka in situ e kūlike, aia nā puka uila e hoʻāʻo ai i ke kū waena. Hoʻoponopono i ka ʻaoʻao hoʻololi o ka puka he pololei, hana maʻalahi, me ka loop interlocking i ka hoʻāʻo pili ʻoihana pili, pono e maʻalahi ka mea hoʻoponopono pneumatic hoʻāʻo, ʻaʻohe leakage a me nā ʻano ʻano like ʻole, pono ka hoʻāʻo e hoʻōki i ka hoʻāʻo i ka wā maʻamau, e hoʻomaopopo i nā limahana mālama pono e hana. me.
Unit 2, i kēlā me kēia manawa e hoʻomaka ai ʻoe e like me nā ʻōlelo o ka hana e pili ana, pono e pani ʻia ka puka wai ShuFang e ke kānāwai, ua pio kēlā me kēia puka wai ShuFang (10 mau hola) ma hope o 6 mau hola, ma hope o ka puka wai. o ka hydrophobic wela hōʻike, pono e hoʻokumu 'ia ma luna o ka valve paipu ma hope o ka nānā 'ana a me ka hoʻokolokolo 'ana i ka valve leakage, wela e hōʻike ana aohe mahana e hoike ana i ka lahilahi ma hope o watergate, ka infrared thermometer ua hoʻohana 'ia e ana i ka wela o ka mua a me ka hope paipu paia o. ʻo ka valve a i ʻole ka manaʻo e hoʻoholo inā e kahe ana ka valve. E like me ka uila a pneumatic valve leakage, pono e pani i ka hydrophobic uwila puka a pneumatic puka manual kaawale puka, no ka hydrophobic uila puka, pneumatic puka me ka manual kaawale puka, e like me leakage, e luluia e pani i ka uila puka, a nalowale a pili mālama mālama. E like me ka leakage puka lima, ka nalo a me ka mālama mālama mālama.
3, i kēlā me kēia manawa ma mua o ka pani ʻana o ka ʻāpana, pono e nānā ʻia nā hemahema o ka valve (leakage), pono e kau ʻia ka leakage valve a hoʻomaopopo i ka ʻoihana mālama pono.
4. I ka wehe ʻana a me ka hoʻomaha ʻana a i ʻole me ke kaʻina hoʻoheheʻe kaomi, ma hope o ka wehe ʻana o ka puka wai (discharge) wai, e nānā inā he mahana ma hope o ka valve a i ʻole throttle hole (trap), e hōʻoia e hiki ke pāʻani i ka hana o hoʻokuʻu (hoʻokuʻu) wai, e pale i ka ʻino i hana ʻia e ka wai paipu wela ma muli o ka paʻa ʻana o ka valve a i ʻole pipeline a i ʻole puka throttle (trap).
O KA VALVE PENI A ME KA PALAPALA E PENA IA KA VALVE MATERIAL IDENTIFICATION E PENI ANA I KA ILI IMI MEKEIA OLE O KE KINO VALVE A ME KA PALAPALA, A ME KA HOIKE ILI HOOLAHA E PENI IA MA KA LIMA LIMA HANA, KA PALAPALA, A ME KA PALAPALA. E like me ka mea i hoakakaia ma ka pakaukau malalo. ʻO ke kala pena o ka mīkini hoʻouna i hōʻike ʻia penei: mea uila, ʻano maʻamau i pena ʻia i ka hina hina; ʻEkolu i loko o hoʻokahi (waho, pahū-hōʻoia, anti-corrosion) ʻano pena polū lani; Pneumatic, hydraulic, gear transmission a me nā mīkini hoʻoili ʻē aʻe me ke kala huahana valve.
1. Hoʻomaopopo i nā ʻāpana valve
Ma ka pūpū o ka valve valve, aia kahi laina ākea me ka pua. ʻO nā helu ma luna aʻe o ka laina ākea e hōʻike i ka pae kaomi nominal, a ʻo kekahi e hōʻike i ke ʻano wela a me ke kaomi hana. No ka laʻana, hoʻohana ʻia ʻo PNl0 a me PT510 ma lalo o nā palena hana o 10MPa a me 510 ℃. ʻO ka helu ma lalo o ka laina ākea e hōʻike ana i ke anawaena inoa o ka paipu hoʻohui.
→ hōʻike i ka holo pololei ʻana o ka valve, ka ʻaoʻao waena a me ke kahe kahe o waho, ma ka laina waena like a i ʻole.
Hōʻike ʻo Chrysene > he ʻano kihi ʻākau ka ʻāpana valve, hana ka mea waena ma ka ʻaoʻao pani.
E hōʻike ana he ʻekolu ala o ka valve a he mau ʻaoʻao kahe ka waena.
