ductile iron rubber seal butterfly valve

ʻO Henry Pratt kahi mea hana nui o nā valves a me nā mea pono, me ka ʻoi aku o 60 mau makahiki o ka ʻike lawelawe ma ka ʻoihana mana.
Ua komo ʻo Pratt i ka ʻoihana mana ma o ka hana mālama ma ka Federal Edison Building ma Chicago. ʻO kēia wahi kekahi o nā kahua hana uila nui o Edison i kēlā manawa. Pono ka pahu i loko o kahi paipu wai i kēia manawa ʻaʻohe valve a he lumi poʻo liʻiliʻi. Ua noi ʻia ʻo Henry Pratt e hoʻolālā i kahi valve paʻa e hoʻoponopono i kēia pilikia. ʻO ka hoʻolālā i hana ʻia ʻo ia ka valve butterfly noho elastic, kahi lā e lilo i huahana nui o ka hui.
A hiki i ka waena waena o 1940s, ua hoʻomau ʻo Pratt i ka hana ʻana i nā valve elastic sealing butterfly e like me nā kūlana kikoʻī, akā ma hope o ke Kaua Honua II, ua hoʻoholo ʻo Pratt e hoʻomohala i ka valve ma ke ʻano he laina huahana no ka mana a me nā noi mea kanu wai. I kēia lā, he alakaʻi ʻo Henry Pratt i ka mākeke mana a me ka wai.
ʻO ka 1100 series nuclear water valve he ASME level 2 a me 3 nuclear safety related water supply butterfly valve, e piʻi ana i ka nui mai 6 iniha a 36 iniha (a ʻoi aku ka nui inā pono). He kūpono ka papa hoʻolālā no ANSI 150 # maʻamau kaomi maʻamau. No nā kiwikā ʻoi aku ka nui ma mua o 24 iniha, 75 psig ka helu lawelawe, hiki iā ASME Sec. III waeʻano helu 1678, loaʻa.
ʻO nā hiʻohiʻona hoʻolālā o ka moʻo 1100 e pili ana i ke kino flange, i hana ʻia me nā mea i kūpono me SA-216, Gr. WCB a i ʻole SA-516, Gr. 70; ʻO kahi disc valve, hiki ke hana ʻia a hoʻolei ʻia a i ʻole ke kila kalapona. ʻO ka disc carbon steel he lihi noho valve kila, e uhi ana i ka laulā holoʻokoʻa o ka ʻili o ka noho valve; a me kahi noho kiwi kīpē, i hoʻopaʻa mau ʻia a i ʻole mechanically i hoʻopaʻa ʻia i loko o ke kino valve me ka hoʻohana ʻole i nā mea hoʻopaʻa kaula. Hiki i ka pahu valve ke hana i hoʻokahi ʻāpana e hoʻonui i ka disc valve, a i ʻole hiki ke komo i kahi ʻāpana ʻelua i hoʻokomo ʻia i loko o ka hub disc valve.
ʻO ka 1200 series nuclear air valve he ASME Class 2 a me Class 3 nuclear safety related ea butterfly valve, mai ka 6 iniha a 48 iniha. ʻO ka pae hoʻolālā e like me ka 1100 series.
ʻO nā hiʻohiʻona hoʻolālā o ka moʻo 1200 e like me nā mea o ka moʻo 1100, me kahi kino flange, kahi pahu pahu pahu i hana mua ʻia a hoʻolei ʻia paha me kahi noho paʻa mechanical a hiki ke hoʻololi ʻia, a me kahi ʻāpana hoʻokahi a i ʻole ʻāpana ʻelua. .
ʻO ka 1400 series nuclear water valve he ASME level 2 a me 3 nuclear safety related water supply butterfly valve, mai ka 3 iniha a 24 iniha. He kūpono ka papa hoʻolālā no ka papa kaomi maʻamau ANSI 150#.
Hoʻohālike nā hiʻohiʻona hoʻolālā a me nā mea hana o ka moʻo 1400 i ka moʻo 1100 no ka mea ua like kā lākou hoʻohana.
Hoʻokō ʻo Triton XR-70 rubber-sealed butterfly valve i nā koi AWWA C504, mai ka 24 iniha a 144 iniha. ʻO nā ʻano kino valve maʻamau, ʻo ia ka flange x flange end, mechanical joint (MJ) end (24 inches-48 inches), and flange and MJ end (24 inches, 30 inches, and 36 inches).
ʻO nā hiʻohiʻona Triton e pili ana i ka hoʻolālā noho ʻo Pratt E-Lok a me ka hoʻolālā ʻana o ka pā. Hoʻolālā ʻia ka hoʻolālā noho valve E-Lok, a ua hoʻokomo ʻia ka noho valve rubber i loko o ke kino valve e hāʻawi i ka pani ʻana i ka ea. Loaʻa ka ikaika kiʻekiʻe me ka paona māmā ma mua o nā hoʻolālā pā ʻē aʻe i kēia manawa ma ka mākeke. Ka loulou hui www.henrypratt.com
Nūhou ikehu a me nā ʻatikala hohonu e pili ana i nā mea hou o ka ikehu a me nā ʻano i nā kālepa mea hoʻolako ikehu hou loa, ka ikehu hou, ka lā, ka makani waho, ka wai wai, ka lanahu, a me ka mana nukle.
