Me kahi hoʻolālā piha pololei, pololei a ʻekolu ala paha, he liʻiliʻi a māmā kēia mau kiwikā, e kūpono ana no ka hana pinepine. ʻO ka hoʻohuli maʻalahi ʻana he 90 kekelē wale nō ka mea e pono ai e wehe a pani paha i ka kiwikā, e hoʻomaʻalahi ana i ka automation maʻalahi a me ka mana mamao me ka mālama ʻana i nā kumukūʻai mālama haʻahaʻa.
Ka Paʻa a me ke Ola Lawelawe Lōʻihi ma nā ʻĀina ʻIno
Ua hōʻoia ʻia ka waiwai maoli o kahi valve plug kila kila super ma lalo o nā kūlana koʻikoʻi.
Ke kū'ē ʻana i ka palaho
Nā mea hoʻohuihui super austenitic (e laʻa,UB6, 904L, 254SMO, AL-6XN) hōʻike i ke kūpaʻa kūikawā i kahi ākea o nā media corrosive, e hiki ai ke hana paʻa i nā wahi me ka pH mai 0 a 14. Pale pono kēia i ka hōʻino ʻana o ke kūkulu ʻana i hoʻokumu ʻia e ka hoʻouka kemika.
Ke kū'ē ʻana i ke ana wela a me ke kaomi kiʻekiʻe
Ua kūkulu ʻia kēia mau kiwikā e kū i nā kūlana lawelawe koʻikoʻi, e lawelawe ana i nā mahana a hiki i ka 400°C a me nā helu kaomi a hiki i ka 16MPa. ʻO nā huahana a NSW Valve, no ka laʻana, ua hoʻolālā ʻia no kahi pae mahana o -40°C a i 400°C a hoʻokō i nā koi ʻokoʻa kaomi o 1.0-2.5MPa a ʻoi aku, e kūpono ai no nā noi petrochemical a me ka hana mana.
Ka Hana Mekanika a me ka Pono Sila
Hāʻawi nā kila kila kila loa i kahi hui maikaʻi loa o ka ikaika kiʻekiʻe a me ka paʻakikī, e hōʻoiaʻiʻo ana i ke kino valve a me nā ʻāpana kūloko e kūʻē i ka deformation ma lalo o ke kaomi kiʻekiʻe a me ke kahe ʻana o ke kahaha. ʻO ka hoʻolālā sila paʻa e hōʻoiaʻiʻo i ka hana paʻa leak ʻoiai ma hope o ka holo kaʻapuni lōʻihi, e kūlike ana me nā kūlana koʻikoʻi e like me API 607.
Ka Hoʻokō Kumukūʻai: He Hoʻopukapuka Lōʻihi
ʻOiai ʻoi aku ka nui o ka hoʻopukapuka mua ʻana i kahi valve plug kila kila maikaʻi ma mua o kahi valve maʻamau, he hoʻopukapuka koʻikoʻi ia no ka wā lōʻihi. ʻO ke ola lawelawe i hoʻolōʻihi nui ʻia, ka emi ʻana o ke alapine o ka hoʻololi ʻana, a me nā koi mālama liʻiliʻi e alakaʻi ai i ka emi nui o ke kumukūʻai o ka loaʻa ʻana (TCO). ʻO ka pale ʻana i ka downtime i hoʻolālā ʻole ʻia, nā pohō hana, a i ʻole nā hanana kaiapuni ma muli o ka hāʻule ʻana o ka valve e hāʻawi i nā pono kālā a me ka hana nui.
Nā Noi ʻOihana o nā Kiwikā Plug Super Stainless Steel
ʻO kēia mau kiwikā ka koho makemake ʻia ma nā ʻoihana kahi e koʻikoʻi ai ka hana.
ʻOihana Petrochemical
Hoʻohana ʻia i nā lako hana ʻokiʻoki, hoʻoili, a me ka hoʻomaʻemaʻe ʻana i ke kahua aila—e like me nā mea hana poʻo luawai, nā paipu hoʻoili, a me nā mana hoʻokele komo/puka ma nā pahu mālama aila maka. ʻO ko lākou hiki ke kaomi kiʻekiʻe (ma luna o 10MPa) a me ke kūpaʻa i ka palaho e mālama i nā sulfides a me nā hui ʻino ʻē aʻe i loko o ka aila maka.
Hoʻoili Kinoea Kūlohelohe
He mea nui no ka kaohi ʻana i ke kahe ʻana ma nā paipu mamao loa, nā kikowaena hoʻoponopono kaomi, a me nā kikowaena compressor, kahi e pono ai lākou e kū i nā kaomi ma luna o 20MPa. ʻO nā mea hana pinepine he nickel-based alloys a i ʻole nā kila kila super stainless e kūʻē i ka hydrogen embrittlement, e hōʻike ana i nā hoʻolālā sila anti-static a me ka maikaʻi.
Ka Mana Hoʻomalu Kemika ʻAiʻino
Kūpono no ka lawelawe ʻana i nā paipu e loaʻa ana nā hopena waikawa/alkali, nā mea hoʻoheheʻe ikaika (e laʻa, ka waikawa nitric), a i ʻole nā mea hoʻoheheʻe organik. ʻO nā ʻāpana i pulu ʻia, i hoʻopaʻa pinepine ʻia me ka PTFE a i hana ʻia mai nā mea hao e like me Hastelloy, hāʻawi i ke kūpaʻa ʻana i ka pala e pono ai me nā hiʻohiʻona palekana e like me ka hoʻolālā palekana ahi.
Mana Media Cryogenic
Kūpono no nā noi kinoea wai e like me ka LNG (kinoea kūlohelohe wai, a hiki i -162°C) ma nā wahi komo/puka o ka pahu mālama a me nā kikowaena hoʻouka. Hana ʻia nā kino valve mai nā kila kila i mālama kūikawā ʻia no ka lawelawe haʻahaʻa haʻahaʻa, me nā sila i hana ʻia mai nā mea e like me ka laholio EPDM.
Hoʻohālikelike: Nā Kiwikā Plug Super Stainless vs. Nā ʻAno Kiwikā ʻē aʻe
ʻO ka Valve Plug kila kila Super Vs.Kiwikā Pōpō
• Ke ʻano sila a me ka hilinaʻi:Hoʻohana nā kiwikā plug i kahi hoʻolālā plug tapered e hāʻawi ana i kahi ʻili sila nui aʻe a me kahi hana wedging. ʻO ka hopena pinepine kēia i kahi sila hilinaʻi a paʻa i ka pehu i hoʻohālikelike ʻia me ka laina pili o nā noho o ka kiwikā pōpō, ʻoi aku hoʻi i nā noi me nā ʻāpana abrasive a i ʻole ka holo kaʻa pinepine e hiki ai ke hoʻopau i nā noho kiwikā pōpō.
• Hoʻohana ʻana i ka Torque:ʻO ka maʻamau, ʻoi aku ka haʻahaʻa o ka torque hana o ka valve pōpō, ʻoiai i ka wā e huli hapaha ai. Eia nō naʻe, hana maikaʻi kahi valve plug i hoʻoluʻu pono ʻia.
• Kūpono:ʻOiai ʻoi aku ka maikaʻi o nā kiwikā poepoe i ka lawelawe on/off no nā wai maʻemaʻe, ʻoi aku ka maikaʻi o nā kiwikā plug kila kila super no ka lawelawe ʻana i nā slurries, nā wai viscous, a me nā mea abrasive ma muli o kā lākou hana holoi a me ka sila ʻana i ʻoi aku ka ikaika.
ʻO ka Valve Plug kila kila Super Vs. Valve Gate
ʻO ka hoʻohālikelike ʻana ma waenanā kiwikā plug kila kila kiʻekiʻea menā kiwikā pukake nānā nui nei i ko lākou mau ʻano hoʻonohonoho, nā noi kūpono, a me nā ʻokoʻa hana:
• ʻAno a me ke Kumumanaʻo Hana
Hāmama a pani ʻia nā kiwikā plug ma ka hoʻohuli ʻana i ke plug i 90 degere. Hilinaʻi ko lākou ʻili sila ma ka pili pololei ma waena o ke plug a me ka noho kiwikā, akā hoʻomaikaʻi ke kila kila kila i ka hana sila. Ma ka ʻaoʻao ʻē aʻe, hāmama a pani ʻia nā kiwikā puka ma ka hāpai ʻana a me ka hoʻohaʻahaʻa ʻana i ka disc puka. Hilinaʻi ko lākou sila ma ka friction ma waena o ka disc a me ka noho kiwikā, a ʻo ka wehe ʻana hapa lōʻihi e hiki ke alakaʻi maʻalahi i ka ʻaʻahu ʻana.
• Kaomi a me ka Mahana e pili ana
He kūpono nā kiwikā plug kila kila kiʻekiʻe no nā noi kaomi haʻahaʻa a waena (maʻamau ≤ 1.6 MPa). Ma muli o ko lākou sila e hilinaʻi ana i ka pili pololei, ua maʻalahi lākou i ka leakage i nā kaomi kiʻekiʻe. Ma ka ʻaoʻao ʻē aʻe, hiki i nā kiwikā puka ke kū i nā kaomi kiʻekiʻe a kiʻekiʻe loa (e like me nā ʻāpana hydrogenation petrochemical) a hoʻokō i ka sila hilinaʻi ma o ka hoʻolaha ʻana o ke kaomi media.
• Hoʻohālikelike Media
ʻOi aku ka kūpono o nā kiwikā plug no nā mea maʻemaʻe a haʻahaʻa ka viscosity (e like me ka wai a me ka ea). Hiki i nā mea i loaʻa nā ʻāpana a i ʻole ka viscosity kiʻekiʻe ke hoʻopili maʻalahi. He kūpono nā kiwikā puka no nā ʻano mea like ʻole (me nā kemika ʻino iki) a kūpono loa no nā noi e pono ai ka pani ʻana o ka wai.
• Hana a me ka Mālama ʻana
He haʻahaʻa ka torque wehe a pani ʻana o nā kiwikā plug a ʻaʻohe friction, e maʻalahi ai ka mālama ʻana (hiki ke wehe koke ʻia nā haumia). He nui ka torque hana o ka kiwikā puka, a maʻalahi ka pau ʻana o ka ʻili sila ma hope o ka hoʻohana lōʻihi. Hiki i ka mea i loaʻa nā haumia ke hoʻoulu i ka liki.
Mea a me ke kūpaʻa ʻana i ka palaho
ʻO ka mea hoʻokaʻawale koʻikoʻi ka mea hana. Hoʻohana ka Super Stainless Steel Plug Valve i nā mea hoʻohuihui holomua (e laʻa, duplex, super duplex, super austenitic) e hāʻawi ana i ke kū'ē nui loa i ka pitting, crevice corrosion, a me ka stress corrosion cracking (SCC) ma mua o ka Stainless Steel Ball Valve maʻamau i hana ʻia mai 316SS, ʻoi aku hoʻi i nā wahi chloride kiʻekiʻe.
Nā Manaʻo Mālama no ka Hana Kūpono Loa
E hoʻonui i ke ola o kāu mau valves me ka mālama pono.
Mālama Sila
E nānā pinepine i nā ʻili o ka plug a me ke kino no ka ʻaʻahu a i ʻole ka pala. E hoʻomaʻemaʻe pono e wehe i nā ʻōpala i hōʻiliʻili ʻia e hiki ke hōʻino i ka sila.
Hoʻokele Lubrication
No nā kiwikā plug i lubricated ʻia, e mālama i ka lubrication kūpono ma ka hoʻokomo ʻana i kahi grease hana kiʻekiʻe kūpono (e like me EL-80) e like me ka ʻōlelo ʻia e hōʻoia i ka hana maʻalahi a pale i nā ʻili sila.
Nā Alakaʻi Hana
E hoʻohana pono a kaulike i ka valve ma o kona huli ʻana he 90 kekelē. E pale i nā hopena haʻalulu a i ʻole ka ikaika nui. Inā paʻakikī ka hana ʻana, e noiʻi i ke kumu ma mua o ka hoʻoikaika ʻana.

E hoʻokō i kahi papa hana nānā maʻamau. Paipai ʻia nā nānā mahina no nā leaka waho a me ka pala. Pono e hana ʻia i kēlā me kēia hapaha, nā nānā pono ʻana o ka actuator (inā loaʻa) a me ka ʻōnaehana lubrication.
Ke koho ʻana i ka mea hoʻolako valve kūpono
ʻO ke koho ʻana i kahi hoa hana ʻoi aku ma mua o ke kūʻai ʻana i kahi huahana. E koho i kahi mea hoʻolako a me kahi hale hana valves kila kila kiʻekiʻe e like me NSW Valve e hāʻawi ana i:
• Hana ʻana ma loko o ka hale:Ka mana ma luna o ke kaʻina hana holoʻokoʻa, mai ke koho ʻana i nā mea a hiki i ka mīkini ʻana.
