API 6D Piha Kikoo Koli Puka piha
✧ Hōʻike
ʻO ka API 6D maʻamau ka wehewehe ʻana i nā koi no nā valveline pipeline, me nā kikoʻī no nā ʻano valve he nui, mai nā ʻīpuka ʻīpuka e nānā i nā kiwi. ʻO ka piha piha piha o ka port swing check valve i hoʻolālā ʻia e like me API 6D e hoʻokō i nā kūlana ʻoihana kūikawā a me nā koi no kāna hoʻolālā ʻana, nā mea waiwai, nā ana, a me nā kaʻina hana hoʻāʻo. ka pale ʻana i ka hoʻihoʻi ʻana ma ka ʻaoʻao ʻē aʻe. Wehe ka diski koli i loko o ka pahu i ke ala o ke kahe ʻana a pani ʻia e pale i ke kahe ʻana. Hoʻohana pinepine ʻia kēia ʻano valve i nā noi kahi e koʻikoʻi ai ka pale ʻana i ka backflow, e like me nā pipelines, refineries, a me nā mea kanu kaʻina.
✧ Nā hiʻohiʻona o ka API 6D Full Port Swing Check Valve
1. He pōkole ka lōʻihi o ke kūkulu ʻana, a ʻo ka lōʻihi o ke kūkulu ʻana he 1/4 a hiki i ka 1/8 wale nō o ka valve check flange maʻamau;
2. ʻO ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, a ʻo kona kaumaha he 1/4 wale nō i ka 1/20 o ka pahu hoʻopaʻa micro-retarding maʻamau;
3. Paʻa koke ka disc valve a liʻiliʻi ke kaomi hāmare wai;
4. Hiki ke hoʻohana ʻia nā paipu horizontal a kūpaʻa paha, maʻalahi e hoʻokomo;
5. Kaila kahe maʻemaʻe, haʻahaʻa ka pale wai;
6. Hana maʻalahi, hana hoʻopaʻa maikaʻi;
7. ʻO ka pōkole pōkole o ka pahu pahu, ka hopena liʻiliʻi o ka pani pani;
8. ʻO ke ʻano holoʻokoʻa, maʻalahi a paʻa, ʻano nani;
9. Ke ola lōʻihi a me ka hilinaʻi kiʻekiʻe.
✧ Pono o API 6D Full Port Swing 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.
He pōkole ka wehe ʻana a i ʻole ka pani ʻana o ka pahu valve, a he mea hilinaʻi loa ia i ka hana ʻoki ʻia, a no ka mea ʻo ka hoʻololi ʻana o ke awa noho valve e like me ka hahau ʻana o ka disc valve, ua kūpono loa ia no ka hoʻoponopono ʻana i ke kahe kahe. No laila, kūpono loa kēia ʻano valve no ka ʻoki ʻana a i ʻole ka hoʻoponopono a me ka throttling.

✧ Mahope o ke kuai ana
Ma ke ʻano he ʻoihana API 6D Full Port Swing Check Valve a me ka mea kūʻai aku, hoʻohiki mākou e hāʻawi i nā mea kūʻai aku i ka lawelawe ma hope o ke kūʻai aku kiʻekiʻe, 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.
