He aha nā mea ʻokoʻa ma waena o nā kiwikā o ʻAmelika a me nā hae paʻamau o Kelemania?

(American standard, German standard, national standard) ka ʻokoʻa ma waena o nā kiwikā:

ʻO ka mea mua, mai ke code standard o kēlā me kēia ʻāina hiki ke ʻike ʻia: ʻo GB ka pae ʻāina, American standard (ANSI), German standard (DIN). ʻO ka lua, hiki iā ʻoe ke hoʻokaʻawale mai ke k modelkohu, ka inoa o ka nohona kiwikā maʻamau i kapa ʻia e like me nā leka pinyin o ka mahele kiwikā. ʻO kahi laʻana, ʻo ka palekana palekana ʻo A, kiwikā pēpē D, diaphragm kiwikā G, hōʻoia kiwikā ʻo H, pōpō honua J, kiwikā L, pāwili hoʻowelewewe P, pōpō kinipōpō Q, pahele S, puka puka Z a pēlā aku.

ʻAʻohe mea kikoʻī kūikawā ma waena o ke kiwikā maʻamau o ʻAmelika, ka nohona Kelemania maʻamau, ka nohona kaulike aupuni, ʻaʻohe mea ʻē aʻe ma mua o ka ʻokoʻa ma waena o ka pae hana a me ka pae kaomi, maʻalahi ka mea o ke kino kiwikā a me nā mea o loko, ʻaʻohe mea ʻē aʻe o ka hao hao wale nō, kiola kila, kila kila, a pēlā aku. American Standard, ʻo kahi laʻana, mai 125LB a i 2,500 lb (a i ʻole 200PSI a i 6,000 psi). ʻO ke API nui o ka maʻamau, ʻo ANSI, kahi i kapa ʻia ʻo API, nā valves ANSI. ʻO Kelemania kaomi kaomi maʻamau maʻamau PN10 i PN320, e hoʻohana ana i ka standard DIN; Inā hoʻā ʻia ka kiwikā, e hoʻohana i ka hae flange kūlike. ʻO nā kūlana o ka nohona kiwikā o ka honua ʻo ka standard standard ʻAmelika ʻaila ʻaila ʻaila ʻAmelika, ANSI maʻamau no ʻAmelika, DIN maʻamau Kelemania, JIS hae Japanese, GB, ʻEulopa kūlana EN, Pelekane Pelekania BS.

Ma ka ʻōlelo maʻalahi ʻana, hoʻolālā ʻia, hana, hana a hoʻāʻo ʻia nā kiwikā o ʻAmelika e like me nā kūlana ʻAmelika. Hoʻolālā, hana, hana a hoʻāʻo ʻia nā kiwikā Kelemania e like me nā kūlana Kelemania. ʻO ka nohona kūlana maʻamau, e like me ka hoʻolālā maʻamau a Kina, hana ʻana, hana ʻana, ʻike ʻia o nā kiwikā.

ʻOkoʻa ka ʻokoʻa ma waena o nā mea ʻekolu: 1, ʻaʻole like ke ʻano o ka flange; 2, ʻokoʻa ka lōʻihi o ke ʻano; 3. ʻOkoʻa nā koi nānā.

ʻO ke kiʻekiʻena ʻAmelika, ka nohona Kelemania maʻamau, ka nohona kiwikā o ke aupuni ma mua o ka hoʻouka ʻana pono e hana i ka nānā pono kiwikā a me ka hana hoʻāʻo, i mea e hōʻoia ai i ka hoʻohana maʻamau i ke kūlana hana, akā e hana i kahi hana maikaʻi i ka palekana o kahi pale. hana. ʻO ke kaomi hoʻāʻo ka mea e hana kiʻekiʻe loa, ka haʻahaʻa hana haʻahaʻa a me ka haʻahaʻa haʻahaʻa haʻahaʻa. ʻO ka hana maʻalahi a me ka liu ʻole o ka mahu e manaʻo ʻia he kūpono.

ʻO ka standard American pressure pressure pressure standard: he 1.5 mau manawa ke kaomi nominal, ʻo ka manawa hoʻāʻo ʻo 5min, ʻaʻole i haki ka manawa hoʻāʻo o ke kino kiwikā, ʻaʻohe deformation, ʻaʻole kīkaha ka wai i ka wai, ʻaʻole hāʻule ke ana kaomi ma ke ʻano he kūpono. Ma hope o ka hōʻoia o ka hōʻoia ikaika, lawe hou ʻia ka hōʻoia paʻa. Hoʻohālikelike ke kaomi hoʻāʻo paʻa me ka kaomi nominal. ʻAʻohe kulu o ka kiwikā i ka manawa o ka hoʻāʻo, a ʻaʻole i hāʻule ke ana o ke kaomi i hiki ke koho ʻia.
