GDF-1 Poepoe Poepoe Kikoʻi Kūikawā no ka Pipeline Gas

Helu Kumu: GDF-1

ʻO ka wehewehe pōkole:

ʻO GDF-1 ʻea pipeline kūikawā valve he valve i hoʻohana ʻia ma nā pipeline kinoea e hoʻomalu i ka on-off o ka mea hoʻouna. Hiki ke hoʻokomo ʻia ma ka pipeline kinoea ma ke ʻano he ʻāpana kūʻokoʻa a hiki ke hoʻokele pono i ka on-off o ke kinoea hilinaʻi; hiki ke hoʻohana pū ʻia me ka mika kahe e ʻike ai i ka hoʻohui ʻana o ka pipeline gas metering a me ka mana on-off.

Nā Pono Huahana

ʻO ka hiʻohiʻona a me nā mea maikaʻi o ke kinoea pipeline ball valve
1. He nui ke kaomi hana, a hiki ke wehe ʻia ka valve a pani paʻa i ka hana o 0.4MPa.
2. He pōkole ka manawa wehe a me ka pani ʻana o ka valve, a ʻoi aku ka liʻiliʻi o ka manawa wehe a me ka pani ʻana ma mua o 50s ma lalo o ka palena o ka volta hana o 7.2V.
3. ʻAʻohe poho puʻe, a ua ʻae ʻia ka hoʻolālā ʻana o ka hoʻolālā ʻana o ka pohō ʻole me ke anawaena valve e like me ke anawaena paipu.
4. He maikaʻi ka hana hoʻopaʻa ʻana o ka valve pani, a ua hana ʻia ke sila me ka nitrile rubber me ke kiʻekiʻe o ka wela (60 ℃) a me ka haʻahaʻa haʻahaʻa (-25 ℃).
5. Me ka hoʻololi palena, hiki iā ia ke ʻike pono i ke kūlana i loko o ke kūlana o ka valve hoʻololi.
6. Holo mālie ka valve on-off, me ka haʻalulu ʻole a me ka walaʻau haʻahaʻa.
7. Hoʻopaʻa piha ʻia ka mīkini a me ka pahu pahu, a ʻo ka pae palekana ʻo ≥IP65, ka mea e pale pono ai i ke komo ʻana o ka mea hoʻouna, a he hana pahū maikaʻi.
8. Hana ʻia ke kino valve me ka alumini, hiki ke kū i ka kaomi 1.6MPa, pale i ka haʻalulu a me ka haʻalulu, a hoʻololi i nā ʻano paʻakikī.
9. He anodized ka ili o ke kino valve, he nani a maʻemaʻe a he hana anti-corrosion maikaʻi.

A'o no ka hoohana

1. ʻO ka uea ʻulaʻula a me ka uea ʻeleʻele nā ​​uea mana, ua hoʻopili ʻia ka uea ʻeleʻele i ka electrode maikaʻi, a ua hoʻopili ʻia ka uea ʻulaʻula i ka electrode maikaʻi ʻole e wehe i ka valve.
2. ʻO nā laina hoʻopuka hōʻailona koho koho: 2 mau laina keʻokeʻo nā laina hōʻailona valve-wehe i ke kūlana, kahi pōkole i ka wā e kau ai ka valve; ʻO nā laina polū 2 nā laina hōʻailona valve-kokoke i ke kūlana, kahi pōkole pōkole i ka wā e paʻa ai ka valve; (Ma hope o ka wehe ʻana a i ʻole ka pani ʻana o ka valve, hoʻonui pinepine ʻia ka lako mana no 5s e hōʻoia i ka paʻa o ka hōʻailona i ke kūlana)
3. ʻO ka pahu deceleration o ka valve hiki ke hoʻololi i ka 180 degere holoʻokoʻa e like me ka maʻalahi o ka mea kūʻai e hoʻokomo i ka pahu hoʻomalu, a hiki ke hoʻohana maʻamau i ka valve ma hope o ka hoʻololiʻana.
4. E hoʻohana i nā bolts flange maʻamau e hoʻohui i nā kiwi, nā paipu, a me nā mika kahe. Ma mua o ka hoʻokomo ʻana, pono e hoʻomaʻemaʻe pono ʻia ka maka hope o ka flange e pale i ka palaka hao, ka ʻōpala, ka lepo a me nā mea ʻoi ʻē aʻe ma ka ʻili hope mai ka ʻoki ʻana i ka gasket a me ka leakage.
5. Pono e hoʻokomo i ka valve i loko o ka pipeline a i ʻole flowmeter me ka pani ʻana o ka valve. Hoʻopaʻa loa ʻia ka hoʻohana ʻana iā ia ma ke ʻano o ka overpressure a i ʻole ka leakage kinoea a ʻike i ka leakage me ke ahi hāmama.
6. Hāʻawi ʻia ke ʻano o kēia huahana me kahi papa inoa.
