Hōʻuluʻulu ʻia nā mea nui o ka koho valve

ʻO ka hapa nui o ka media i nā mea hana kemika i loaʻa nā hiʻohiʻona o ka mea ʻawaʻawa kiʻekiʻe, combustible, explosive a me ka corrosive. He paʻakikī a paʻakikī nā kūlana hana, a kiʻekiʻe ka mahana hana a me ke kaomi. Ke hāʻule ka valve, e alakaʻi ke kukui i ka leakage waena, e alakaʻi ke kaumaha i ka pani ʻana o ka hāmeʻa, a hiki i nā ulia pōpilikia. No laila, ʻaʻole hiki i ka ʻepekema a me ke koho kūpono o ka valve ke hōʻemi wale i ke kumukūʻai o ke kūkulu ʻana o ka hāmeʻa, akā e hōʻoia pū i ka hana palekana o ka hana. E kamaʻilio kākoukoho valve!

ʻO nā mea nui o ka koho valve
1 Hoʻomaʻemaʻe i ka valve i nā mea hana a i ʻole ka hoʻohana ʻana i nā mea hana
E hoʻoholo i nā kūlana hana o ka valve: ke ʻano o ke ʻano kūpono, ke kaomi hana, ka mahana hana a me ke ʻano hana mana.
E koho i ke ʻano valve kūpono
ʻO ka koho kūpono o ke ʻano valve e pili ana i ka mea hoʻolālā o ke kaʻina hana holoʻokoʻa, ka ʻike piha ʻana i nā kūlana hana ma ke ʻano he koi, i ke koho ʻana i ke ʻano valve, pono ka mea hoʻolālā e haku i nā ʻano hana a me ka hana o kēlā me kēia valve.
E hoʻoholo i ka pili hope o ka valve
Ma ka pilina pili, ka pili flange, ka hoʻopili hope ʻana, nā ʻano maʻamau ʻelua mua. ʻO nā kiwi hoʻopaʻa ʻia ka nui o nā valve me ke anawaena inoa ma lalo o 50mm. Inā nui loa ke anawaena, paʻakikī loa ka hoʻokomo ʻana a me ka sila ʻana o ka pilina.
ʻOi aku ka maʻalahi o ka hoʻouka ʻana a me ka wehe ʻana i nā valve Flanged, akā ʻoi aku ka nui a ʻoi aku ke kumukūʻai ma mua o nā valve threaded, no laila kūpono lākou i nā pilina paipu o nā ʻano nui a me nā kaomi.
ʻOi aku ka hilinaʻi o ka pilina welded ma mua o ka pilina flanged, kahi kūpono no ka hoʻouka ʻana i nā kūlana. Akā ʻoi aku ka paʻakikī o ka welded valve disassembly a me ka reinstallation, no laila ʻoi aku ka maʻamau o ka hoʻohana ʻana i ka hana hilinaʻi lōʻihi, a i ʻole ka hoʻohana ʻana i nā kūlana o ka hoʻouka ʻana, nā manawa wela kiʻekiʻe.
4. Ke kohoʻana i nā mea valve
ʻO ke koho ʻana i ka pūpū valve, nā ʻāpana o loko a me ka mea hoʻopaʻa ʻana i ka ʻili, me ka noʻonoʻo ʻana i nā waiwai kino o ke ʻano hana (ka wela, ke kaomi) a me nā waiwai kemika (corrosion), pono e hoʻopaʻa i ke kiʻekiʻe o ka hoʻomaʻemaʻe media (me nā ʻāpana paʻa ʻole a i ʻole. ), i ka hoʻohui, akā e pili pū i nā mea kūpono o ka moku'āina a me ka hoʻohana ʻana i nā keʻena.
ʻO ke koho kūpono a kūpono hoʻi o nā mea valve hiki ke loaʻa i ke ola lawelawe waiwai maikaʻi loa a me ka hana maikaʻi o ka valve. ʻO ke kauoha koho waiwai o ke kino valve: hao – hao kalapona – kila kuhiliʻole, apo apo kauoha koho mea: ʻāpala – keleawe – hao hao -F4.
ʻElima ʻē aʻe
HE HOʻOPIʻI, E hoʻoholo ʻia ka nui o ke kahe a me ke kaomi o ka wai e kahe ana ma o ka VALVE, a pono e koho ʻia ka valve kūpono me ka hoʻohana ʻana i ka ʻike i loaʻa (e laʻa, catalog product valve, sample product sample, etc.).
ʻO ka wehewehe ʻana i ke ʻano koho valve maʻamau
ʻO ke ʻano o ke koho ʻana i ke ʻano o ka puka valve
Ma keʻano laulā, pono e hāʻawi ʻia ka mea nui i nā ʻīpuka puka. ʻO ka pahu puka puka ma kahi kūpono no ka mahu, ka aila a me nā mea hoʻolaha ʻē aʻe, akā pili pū nō hoʻi i loko o ka paʻa granular a me ka viscosity o ka waena, a kūpono hoʻi no nā puka makani a me nā ʻōnaehana haʻahaʻa haʻahaʻa. No ka waena me nā ʻāpana paʻa, e hoʻolako ʻia ke kino kīpē puka me hoʻokahi a ʻelua mau puka hoʻomaʻemaʻe. No ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa wela puka valve pono e koho.
2. ʻO ka wehewehe ʻana i ka koho valve ʻoki ʻia
ʻAʻole i koʻikoʻi ʻo Globe valve no ka hoʻopaʻapaʻa ʻana o ka wai i ka pipeline, ʻo ia hoʻi, ʻaʻole i manaʻo ʻia ka nalo o ke kaomi, a me ka wela kiʻekiʻe, ka pipeline kiʻekiʻe kiʻekiʻe a i ʻole nā ​​mea hana, kūpono no ka DN Hiki i ka valve liʻiliʻi ke koho i ka valve globe, e like me ka valve needle, valve instrument, sampling valve, pressure gauge valve, etc.;
Loaʻa i ka valve honua ka hoʻoponopono kahe a i ʻole ka hoʻoponopono kaomi, akā ʻaʻole kiʻekiʻe ka pololei o ka hoʻoponopono ʻana, a he liʻiliʻi ke anawaena o ka paipu, kūpono ke koho ʻana i ka valve globe a i ʻole throttle valve;
No nā mea ʻawaʻawa loa, kūpono ke koho ʻana i ka pahu pahu i hoʻopaʻa ʻia i ka honua; Akā, ʻaʻole pono e hoʻohana ʻia ka valve globe no ka waena me ka viscosity nui a me ka medium i loaʻa nā ʻāpana maʻalahi e hoʻoheheʻe ʻia, ʻaʻole pono e hoʻohana ʻia e like me ka valve vent a me ka valve o ka ʻōnaehana haʻahaʻa haʻahaʻa.
3. Hōʻikeʻike o ka pōlele koho koho
He kūpono ke kinikini pōlele no ka haʻahaʻa haʻahaʻa, ke kiʻekiʻe kiʻekiʻe, ka viscosity medium. Hiki ke hoʻohana ʻia ka hapa nui o nā kiwi pōpō ma waena me nā ʻāpana paʻa paʻa, e like me nā koi mea e hoʻopaʻa ai hiki ke hoʻohana ʻia i ka pauka a me ka media granular;
ʻAʻole kūpono ka valve ball-channel no ka hoʻoponopono kahe ʻana, akā kūpono ia no ka wehe wikiwiki ʻana a me ka pani ʻana i nā manawa, maʻalahi e hoʻokō i ka ʻoki ʻia; ʻO ka maʻamau i ka hana hoʻopaʻa paʻa paʻa, ʻaʻahu, shrinkage channel, ka wehe wikiwiki a me ka hana pani ʻana, ʻoki ʻoki kiʻekiʻe (nui ka ʻokoʻa nui), haʻahaʻa haʻahaʻa, gasification phenomenon, liʻiliʻi liʻiliʻi hana, ke kūpaʻa wai, ʻae ʻia ka hoʻohana ʻana i nā kiwi pōpō.
He kūpono ka pahu kinipōpō no ka hoʻolālā māmā, ka ʻoki haʻahaʻa haʻahaʻa, ka media corrosive; Poepoe kiwi a haʻahaʻa wela, cryogenic medium o ka pono kiwikā, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa paipu nenoaiu a me ka mea pono, e koho me ka haʻahaʻa wela poepoe uhi uhi;
Pono ka mea e hoʻokō i ka ukana o ka pōleʻa a me ke ʻano hana, ʻoi aku ka ikaika o ka nui o ka pōpō pōleʻa i ka hana, DN≥
200mm ball valve pono e koho i ka worm gear transmission form; ʻO ka valve pōleʻa paʻa kūpono no ka nui o ke anawaena a me nā manawa kiʻekiʻe; Eia kekahi, ʻo ka valve ball i hoʻohana ʻia no ke kaʻina hana o nā mea ʻawaʻawa nui, ka pipeline media combustible, pono ke ahi, anti-static structure.
4. ʻO ka wehewehe ʻana i ke koho throttle valve
ʻO ka valve throttle he kūpono no ka haʻahaʻa haʻahaʻa haʻahaʻa, kiʻekiʻe kiʻekiʻe, kūpono no ka pono e hoʻoponopono i ka kahe a me nā ʻāpana kaomi, ʻaʻole no ka viscosity a loaʻa i nā ʻāpana paʻa paʻa, ʻaʻole pono e hoʻohana ʻia e like me ka valve block.
ʻO ka wehewehe ʻana i ke ʻano o ke koho ʻana i ke ʻano o ka plug valve
He kūpono ke kīpē plug no ka wehe wikiwiki ʻana a me ka pani ʻana, ʻaʻole kūpono no ka mahu a me ke ana wela kiʻekiʻe, no ka haʻahaʻa haʻahaʻa, kiʻekiʻe viscosity medium, kūpono hoʻi no ka waena me nā mea i hoʻokuʻu ʻia.
ʻO ka wehewehe ʻana i ke ʻano o ke koho ʻana i ke ʻano o ka valve valve
He kūpono ka valve Butterfly no ke anawaena nui (e like me DN> 600mm) a me nā koi lōʻihi o ka lōʻihi, a me ka pono o ka hoʻoponopono kahe a me ka wehe wikiwiki a me ka pani ʻana i nā koi, hoʻohana maʻamau no ka mahana ≤
80 ℃, kaomi ≤1.0MPa wai, aila a me ka ea paʻa a me nā mea ʻē aʻe; Ma muli o ke kīpē lele e pili ana i ka valve puka, ʻoi aku ka nui o ka pohō o ka pōleʻa puʻupuʻu, no laila ua kūpono ka valve butterfly no nā koi poho ʻaʻole paʻa i ka ʻōnaehana pipeline.
ʻO ka wehewehe ʻana i ke koho ʻana i ka valve check
He kūpono ka pahu hoʻopaʻa no ka media maʻemaʻe, ʻaʻole pono e hoʻohana ʻia i loko o ke kikowaena me nā ʻāpana paʻa a me ka viscosity nui. I ka ≤40mm, pono ia e hoʻohana i ka valve check lift (* ʻae ʻia e kau ʻia ma ka pipeline horizontal); I ka DN = 50 ~ 400mm, ua kūpono ke hoʻohana ʻana i ke ʻano koʻi ʻano hoʻokiʻekiʻe kiwi (i ka paipu ākea a me ke kūpaʻa hiki ke hoʻokomo ʻia, e like me ka hoʻokomo ʻia ʻana i ka pipeline vertical, kahe waena mai lalo i luna);
I ka DN≥450mm, pono e hoʻohana ʻia ke ʻano buffer check valve; I ka DN = 100 ~ 400mm hiki no hoi ke koho i ka clamp type check valve; Hiki ke hana ʻia ka swing check valve me ke kaomi hana kiʻekiʻe loa, hiki i ka PN ke hōʻea i 42MPa, e like me ka pūpū a me nā mea sila hiki ke hoʻopili ʻia i kekahi ʻano hana a me nā pae wela hana.
He wai, mahu, kinoea, corrosive medium, aila, lāʻau lapaʻau, a me nā mea ʻē aʻe. ʻO ka pae wela o ka hana ma waena o -196 ℃ a me 800 ℃.
ʻO ka wehewehe ʻana i ke koho ʻana i ka valve diaphragm
He kūpono ka diaphragm valve no ka hana wela ma lalo o 200 ℃, kaomi ma lalo o 1.0MPa aila, ka wai, ka waiʻawaʻawa a me ka mea i hoʻopaʻa ʻia, ʻaʻole kūpono no nā mea hoʻoheheʻe organik a me ka medium oxidant ikaika;
Pono e koho i ka weir diaphragm valve, koho weir diaphragm valve e kuhikuhi i kona papa kuhikuhi kahe; Pono e koho pololei ʻia ka wai viscous, ka sima slurry a me ka precipitating medium ma o ka valve diaphragm; Inā ʻaʻole i hōʻike ʻia, ʻaʻole pono e hoʻohana ʻia ka valve diaphragm ma nā laina ʻūhā a me nā mea hana.
