Ma ke ʻano he wehe, pani a hoʻoponopono ʻana i ka mea hana o ka pipeline ea a me ka wehe lepo, kūpono ka valve pepeke ventilation no ka hoʻoulu ʻana, ka wehe lepo a me nā ʻōnaehana palekana kaiapuni i ka metallurgy, mining, sima, ʻoihana kemika a me ka hana mana.

Hoʻopili ʻia ka valve pepeke hoʻoulu ea i loko o ke apo sila me ka mea like me ke kino valve. ʻO kona mahana kūpono e pili ana i ke koho ʻana o ka mea o ke kino valve, a ʻo ke kaomi maʻamau he ≤ 0.6MPa. Hoʻohana nui ʻia ia i nā pipeline ʻoihana, metallurgical, palekana kaiapuni a me nā pipeline ʻē aʻe no ka hoʻoulu ʻana a me ka hoʻoponopono ʻana i ke kahe waena.

ʻO kona mau hiʻohiʻona nui:

1. Hoʻolālā hou a kūpono hoʻi, ʻano kū hoʻokahi, māmā a me ka wehe wikiwiki a me ka pani ʻana.

2. ʻO ka torque hana liʻiliʻi, ka hana maʻalahi, ka mālama ʻana i ka hana a me ka dexterous.

3. Pono e hoʻohana ʻia nā mea kūpono e hoʻokō i nā koi o nā mahana haʻahaʻa, waena a me ke kiʻekiʻe a me nā mea ʻino.

Nā ʻōkuhi loea nui o ka kiwikā pepeke hoʻoulu ea

Anawaena inoa DN (mm): 50 ~ 4800mm
