Helu kumu hoʻohālike:

ʻO ka wehewehe pōkole:

ʻO GDF-5 pipeline ball valve he ʻano o ka pōpō pōlele lana, i hoʻopili ʻia e ka flange. Hiki ke waiho kūʻokoʻa ma luna o ka pipeline e hoʻomalu 'akomi i ka on-off o ke kinoea maoli, ka aila a me nā mea halihali ʻē aʻe; hiki ke hoʻolako pū me ka mika kahe e hoʻomaopopo i ke ana kahe a me ka mana ma luna o ka mea lawe pipeline. Loaʻa iā ia nā hiʻohiʻona o ka hana hilinaʻi, ka manawa wehe pōkole a me ka pani ʻana, a me ke kaomi hana kiʻekiʻe. ʻOkoʻa mai ka pahu pōlele lana maʻamau, ʻo ka puka ea o kēia huahana e hoʻohana i kahi ʻano hoʻomaha hoʻoluhi me nā kuleana waiwai naʻauao kūʻokoʻa. Hoʻokele ʻia ka pahu pōlele lana GDF-5 e kahi micro-motor, a ua hoʻolālā ʻia nā ʻāpana āpau e like me nā kūlana aupuni.

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 wehe ʻana a me ka manawa pani ma mua o 50s ma lalo o ka volta hana palena o 7.2V;
3. ʻAʻohe poho puʻe, a ua ʻae ʻia ka hoʻolālā ʻana o ka hoʻolālā ʻana o ka puʻupuʻu zero-pressure 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 leo 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 aluminika, hiki ke kū i ke kaomi 1.6MPa, pale i ka haʻalulu a me ka haʻalulu, a hoʻololi i nā wahi paʻakikī;
9. He anodized ka ili o ke kino valve, he nani a maʻemaʻe a maikaʻi ka hana anti-corrosion;

A'o no ka hoohana

1. ʻO ka uwea ʻulaʻula a me ka uwea 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. Hiki ke hoʻololi i ka pahu deceleration o ka valve i ka 180 degere holoʻokoʻa e like me ka ʻoluʻolu o ka mea kūʻai aku e hoʻokomo i ka pahu mana, a hiki ke hoʻohana maʻamau ka valve ma hope o ka hoʻololi ʻana;
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. Ua pāpā 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 ākea;
6. Hāʻawi ʻia ke ʻano o kēia huahana me kahi papa inoa.
