API 594 Paʻi Paʻa Paʻa ʻElua
✧ Hōʻike
ʻO API 594 kahi maʻamau American Petroleum Institute e uhi ana i ka hoʻolālā, nā mea waiwai, nā ana, ka hoʻāʻo ʻana, a me ka nānā ʻana i nā kiwi loiloi. ʻO ka mea nui, ke nānā aku nei i nā kikoʻī no nā kīwaha nānā pālua ʻelua, i ʻike ʻia he wafer check valves, i hoʻohana nui ʻia i nā ʻoihana like ʻole me ka aila a me ke kinoea, petrochemical, a me ka hoʻomaʻemaʻe. e pili ana i kā lākou kūkulu ʻana, nā helu kaomi-maha, nā mea waiwai, ka hōʻoia ʻana i ka hoʻolālā, a me nā kaʻina hana hoʻāʻo. Hōʻoia kēia maʻamau i ka hoʻokō ʻana o nā valves i kekahi mau hana a me ka palekana palekana no nā noi e pili ana i ka pale ʻana i ke kahe ʻana. hana maʻalahi kūpono no ka hoʻokomo ʻana ma waena o nā flanges. Hoʻohana pinepine ʻia kēia mau valves no ko lākou haʻahaʻa haʻahaʻa haʻahaʻa, hoʻopaʻa paʻa pono, a me ka maʻalahi o ka hoʻonohonoho ʻana a me ka mālama. e ʻoluʻolu e nīnau no ka ʻike hou aku.
✧ Nā hiʻohiʻona o ka API 594 Dual Plate Check Valve
1. He pōkole ka lōʻihi o ka hale, ʻo 1/4 a i ka 1/8 wale nō ka lōʻihi o ka pahu hoʻopaʻa flange maʻamau.
2. liʻiliʻi liʻiliʻi, māmā ke kaumaha, ʻo kona kaumaha he 1/4 a 1/20 wale nō o ka pahu hoʻopaʻa lohi lohi maʻamau.
3. paʻa koke ka disc o ka pahu hoʻopaʻa paʻa, a liʻiliʻi ke kaomi hāmare wai
4. Hiki ke hoʻohana ʻia ka paipu hoʻopaʻapaʻa a i ʻole ka paipu kū pololei, maʻalahi ke hoʻouka
5. He maʻemaʻe ke ala kahe o ka pahu hoʻopaʻa paʻa, liʻiliʻi ke kūpaʻa wai
6. hana koʻikoʻi, hana hoʻopaʻa maikaʻi
7. He pōkole ka hahau diski, he liʻiliʻi ka hopena pani pani pani
8. ka hale holoʻokoʻa, maʻalahi a paʻa, nani ke ʻano
9. lōʻihi lawelawe ola, hilinaʻi kiʻekiʻe
✧ Pono o ka API 594 Dual Plate Check Valve
I ka wā o ka wehe ʻana a me ka pani ʻana o ka pahu kila kila, no ka mea, ʻoi aku ka liʻiliʻi o ka friction ma waena o ka disc a me ka ʻili hoʻopaʻa ʻana o ke kino valve ma mua o ko ka valve puka, ʻaʻole hiki ke ʻaʻahu.
ʻO ka wehe ʻana a i ʻole ka pani ʻana o ka pahu valve he pōkole, a he hana ʻokiʻoki hilinaʻi loa ia, a no ka mea ʻo ka hoʻololi ʻana o ke awa noho valve e like me ka hahau ʻana o ka disc valve, kūpono loa ia no ka hoʻoponopono. o ke kahe ana. No laila, kūpono loa kēia ʻano valve no ka ʻoki ʻoki a i ʻole ka hoʻoponopono a me ka throttling.

✧ Mahope o ke kuai ana
Ma ke ʻano he API 594 Dual Plate Check Valve a me ka mea kūʻai aku, ke hoʻohiki nei mākou e hāʻawi i nā mea kūʻai aku me ka lawelawe ma hope o ke kūʻai aku ʻana, me kēia mau mea:
1. Hāʻawi i nā alakaʻi hoʻohana huahana a me nā manaʻo mālama.
2.No nā hemahema i hana ʻia e nā pilikia maikaʻi o ka huahana, hoʻohiki mākou e hāʻawi i ke kākoʻo ʻenehana a me ka hoʻoponopono pilikia i loko o ka manawa pōkole loa.
3.Except no ka pōʻino i hanaʻia e ka hoʻohana maʻamau, hāʻawi mākou i ka hoʻoponopono manuahi a me nā lawelawe pani.
4. Ke hoʻohiki nei mākou e pane wikiwiki i nā pono lawelawe o ka mea kūʻai aku i ka wā o ka hōʻoia huahana.
5. Hāʻawi mākou i ke kākoʻo ʻenehana no ka wā lōʻihi, nā lawelawe kūkākūkā pūnaewele a me nā lawelawe hoʻomaʻamaʻa. ʻO kā mākou pahuhopu ka hāʻawi ʻana i nā mea kūʻai aku i ka ʻike lawelawe maikaʻi loa a hoʻolilo i ka ʻike o nā mea kūʻai aku i mea ʻoluʻolu a maʻalahi.
