1. Ke koho ʻana i ka valve puka
Ma keʻano laulā, pono e makemake ʻia nā ʻīpuka puka.ʻAʻole kūpono nā ʻīpuka puka no ka mahu, ka aila a me nā mea hoʻolaha ʻē aʻe, akā no ka mea i loaʻa i nā mea paʻa granular a me ka viscosity nui, a kūpono hoʻi i nā ʻōnaehana ʻōnaehana haʻahaʻa.No ka media me nā ʻāpana paʻa, e loaʻa i hoʻokahi a ʻelua mau puka hoʻomaʻemaʻe i ke kino kīpē puka.No ka haʻahaʻa haʻahaʻa haʻahaʻa, kūikawā haʻahaʻa wela puka valve pono e koho.
2. ʻO ka wehewehe ʻana i ka koho valve honua
He kūpono ke kīpē Globe no nā koi kūpaʻa wai o ka pipeline, ʻo ia hoʻi, ʻaʻole i noʻonoʻo ʻia ka nalowale o ke kaomi, a me ka wela kiʻekiʻe, kiʻekiʻe kiʻekiʻe medium pipeline a i ʻole mea pono, kūpono no ka DN <200mm steam a me nā pipeline media ʻē aʻe;Hiki i nā pahu liʻiliʻi ke koho i ka valve honua, e like me ka valve needle, valve instrument, sampling valve, pressure gauge valve, etc. ʻO ka valve Globe he hoʻoponopono kahe a i ʻole ka hoʻoponopono kaomi, akā ʻaʻole kiʻekiʻe ka pololei o ka hoʻoponopono ʻana, a he liʻiliʻi ke anawaena o ka pipeline. , pono e koho i ka puni honua a i ʻole throttle valve;No nā mea ʻawaʻawa loa, kūpono ke koho ʻana i ka pahu pahu i hoʻopaʻa ʻia i ka honua;Eia nō naʻe, ʻaʻole pono e hoʻohana ʻia ka pahu honua no ka waena me ka nui o ka viscosity a me ka medium i loaʻa nā ʻāpana maʻalahi e hoʻoheheʻe ʻia, ʻaʻole pono e hoʻohana ʻia no ka valve vent a me ka valve system vacuum haʻahaʻa.
3, Bnā kuhikuhi koho valve a pau
He kūpono ke kinipōpō pōleʻa no ka haʻahaʻa haʻahaʻa, ke kiʻekiʻe kiʻekiʻe, ka viscosity o ka waena.Hiki ke hoʻohana ʻia ka hapa nui o nā ʻāpana pōpō me nā mea paʻa paʻa i hoʻopaʻa ʻia i ka waena, e like me nā koi mea hoʻopaʻa i hiki ke hoʻohana ʻia no ka pauka a me ka media granular;ʻAʻole kūpono ka valve ball channel piha no ka hoʻoponopono kahe ʻana, akā kūpono ia no nā manawa e koi ai i ka wehe wikiwiki ʻana a me ka pani ʻana, kahi kūpono no ka hoʻokō ʻana i ka ʻoki ʻana i nā pōʻino;ʻO ka maʻamau i ka hana hoʻopaʻa paʻa ʻana, ʻaʻahu, kaila shrinkage, wehe a pani koke i ka hana, ʻoki ʻoki kiʻekiʻe (ka ʻokoʻa o ke kaomi), haʻahaʻa haʻahaʻa, gasification phenomenon, liʻiliʻi hana torque, liʻiliʻi liʻiliʻi wai kū i ka pipeline, ʻōlelo ʻia e hoʻohana i ka pōlele. ;He kūpono ka pahu kinipōpō no ka hoʻolālā māmā, ka ʻoki haʻahaʻa haʻahaʻa, ka media corrosive;ʻO ke kinikini pōleʻa a i ʻole ka wela haʻahaʻa, ʻo ka cryogenic medium ka valve kūpono loa, ʻo ka ʻōnaehana pipeline haʻahaʻa haʻahaʻa haʻahaʻa a me ka mea hana, pono e hoʻohana ʻia me ka uhi kīwī haʻahaʻa wela wela kinipōpō;Pono ke koho ʻana i nā mea noho pōleʻa pōleʻa e lana ana i ka pōleʻa a me ka haʻahaʻa haʻahaʻa hana, ʻoi aku ka ikaika o ke anawaena pōleʻa i ka hana, pono ke koho ʻia ʻo DN≥200mm ball valve worm gear transmission form;He kūpono ia no ka nui o ke anawaena a me ke kiʻekiʻe o ke kaomi;Eia kekahi, ʻo ka valve pōpō i hoʻohana ʻia no ke kaʻina hana o nā mea ʻawaʻawa nui, combustible medium pipeline, pono e loaʻa kahi ahi ahi, anti-static structure.
4, Tnā ʻōlelo kuhikuhi koho valve hrottle
He kūpono ka pahu throttle no ka haʻahaʻa haʻahaʻa haʻahaʻa, nā manawa kiʻekiʻe, kūpono no ka pono e hoʻoponopono i ka kahe a me nā ʻāpana kaomi, ʻaʻole kūpono no ka viscosity a loaʻa i nā ʻāpana paʻa o ka waena, ʻaʻole ma ke ʻano he pāpaʻi.
5, Plug valve koho kuhikuhi
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.
6, Butterfly valve koho kuhikuhi
ʻO ka valve Butterfly he kūpono ia 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 o ka manawa, hoʻohana maʻamau no ka mahana ≤80 ℃, kaomi ≤1.0MPa ka wai, ka aila a me ka ea paʻa a me nā mea ʻē aʻe;Ke hoʻohālikelike ʻia me nā ʻīpuka puka a me nā kiwi pōleʻa, kūpono nā ʻōkuhi butterfly no nā ʻōnaehana paipu me nā koi lax pressure loss.
7, Check valve koho kuhikuhi
He kūpono nā ʻūpili hoʻopaʻa no ka media maʻemaʻe, ʻaʻole no ka media i loaʻa nā ʻāpana paʻa a me ka viscosity.I ka DN≤40mm, e hoʻohana i ka hoʻokiʻekiʻe ʻana i nā kiwi (ʻae wale ʻia e hoʻokomo ʻia ma nā pipeline ākea);I ka DN = 50 ~ 400mm, kūpono ke hoʻohana ʻana i ka swing lifting check valve (hiki ke hoʻokomo ʻia i ka pipeline horizontal a me ke kūpaʻa, e like me ka hoʻokomo ʻana i ka pipeline vertical, kahe waena mai lalo a 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 wafer check valve;Hiki ke hana ʻia ka swing check valve me ke kaomi hana kiʻekiʻe, PN a hiki i ka 42MPa, e like me ka pūpū a me nā mea sila hiki ke hoʻopili ʻia i kekahi ʻano a me nā pae wela hana.ʻO ka wai, ka mahu, ke kinoea, ke kino kino, ka aila, ka lāʻau lapaʻau, a me nā mea ʻē aʻe. ʻO ka mahana hana o ka mea waena ma waena o -196 ℃ a me 800 ℃.
8, Diaphragm valve koho kuhikuhi
He kūpono ka valve diaphragm no ka haʻahaʻa haʻahaʻa o ka hana ma lalo o 200 ℃, ʻoi aku ka liʻiliʻi o ke kaomi ma mua o 1.0MPa aila, ka wai, ka waiʻawaʻawa a me ka mea i hoʻokuʻu ʻia, ʻaʻole kūpono ia no nā mea hoʻoheheʻe organik a me ka medium oxidant ikaika;Pono e koho ʻia ka pāpaʻi diaphragm abrasive, pono e kuhikuhi i ka pākaukau o nā ʻano kahe;Pono e koho pololei ka wai viscous, slurry sima a me ka ua ma o ka valve diaphragm;ʻAʻole pono e hoʻohana ʻia nā ʻūhā diaphragm ma nā laina ʻūhā a me nā mea hoʻoheheʻe ke ʻole i kuhikuhi ʻia.
ʻOkoʻa nā valves i ka noi, ka pinepine o ka hana a me ka lawelawe.No ka hoʻomalu a hoʻopau ʻana i nā liʻiliʻi liʻiliʻi, ʻo nā valve ka mea nui a koʻikoʻi.He mea koʻikoʻi ke aʻo ʻana e koho i ka valve kūpono.
