ʻO GDF-4 Pipeline Hoʻokiʻoki i ka pahu no ka mīkini holo kinoea

Helu Kumu: GDF-4

ʻO ka wehewehe pōkole:

ʻO GDF-4 pipeline shut-off valve he valve i hoʻohana ʻia ma nā pipeline gas 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.

1. ʻO ka valve wehe lohi a pani wikiwiki, a ʻo ka manawa pani ʻo ≤2s;

2. ʻO ka laulā nui o ke kaomi hana, hiki ke piʻi i ka 0.8MPa;

3. Li'ili'i poho poho;

4. Hoʻopaʻa maikaʻi, kūpaʻa a hilinaʻi hoʻi;

5. ʻO ka hoʻolālā hoʻolālā kūikawā o ka wehe ʻana o ka valve a me ka hoʻoluhi puʻupuʻu hiki ke hoʻomaopopo i ka wehe ʻana o ka valve me ka haʻahaʻa haʻahaʻa a me ka hoʻohana haʻahaʻa haʻahaʻa i loko o ke kaiapuni kiʻekiʻe, e hoʻonui ai i ka hilinaʻi o ka hana valve;

6. ʻO ke kino valve i hanaʻia me ka alumini alumini, he māmā i ke kaumaha a maikaʻi i ke kū'ēʻana i ka corrosion, a hiki ke pale i ke kaomi inoa o 1.6MPa; kū'ē ka hale holoʻokoʻa i ka hopena, haʻalulu, kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ka paʻakai paʻakai, a me nā mea ʻē aʻe, a hiki ke hoʻololi i nā ʻano o waho paʻakikī;

7. Hoʻolālā ʻia ka mīkini a me ka pahu pahu ma ke ʻano he hale paʻa i hoʻopaʻa ʻia, ʻo ≥ IP65 ka pae pale, a ʻaʻohe pilina o ka mīkini a me ka pahu pahu me ka medium transmission, a maikaʻi ka hana pahū. Hoʻomaikaʻi nui ʻia ka hilinaʻi valve a me ke ola lawelawe;

8. He ikaika ka mana hoʻokō, a hiki ke hoʻopaʻa ʻia ma hope o ka wehe ʻana a me ka pani ʻana, a hiki ke lawe ʻia i ka hoʻololi kūlana;

9. Ma hope o ka wehe ʻia ʻana o ka valve a pani ʻia ma kahi, hoʻopaʻa ʻia ka mīkini neʻe e hōʻoia i ka hana ʻole o ka valve ma muli o ka ikaika o waho i ka wā e paʻa ai;

10. Hoʻomaʻamaʻa maikaʻi ʻia ka micro-motor, ʻo ka commutator he gula-plated, a ua hana ʻia nā pulupulu i nā metala makamae, kahi e hoʻomaikaʻi nui ai i ka pale ʻana i ka corrosion a me ka paʻa o ka micro-motor ponoʻī, e hōʻoia ana i ka hana hilinaʻi lōʻihi o ka. kiwi kaʻa;
