ʻO kakiwikā pulelehua ʻokoʻa ʻekoluhoʻohana nui ʻia i nā hiʻohiʻona ʻoihana me nā koi koʻikoʻi no ka hana sila a me ka hiki ke hoʻololi i nā kūlana hana ma muli o kona mau pono koʻikoʻi e like me ka sila ʻole o ka leakage, ke kū'ē ʻana i ke kaomi kiʻekiʻe a me ke kiʻekiʻe o ka mahana, ke kū'ē ʻana i ke kahe haʻahaʻa, ke kū'ē ʻana i ka ʻaʻahu a me ke kū'ē ʻana i ka corrosion. Eia nā hiʻohiʻona i hoʻohana pinepine ʻia:

1. ʻOihana mana uila

Hoʻohana nui ʻia ia i nā ʻōnaehana paila (wai hānai, nā paipu mahu), nā ʻōnaehana desulfurization a me denitrification gas flue, a me nā ʻōnaehana wai e kaapuni ana o nā mea kanu mana wela a me nā kikowaena mana nukelea. No ka laʻana, pono nā paipu mahu nui o nā paila a me nā paipu mahu i hoʻomehana hou ʻia e kū i nā mahana kiʻekiʻe (a hiki i ka 500 ℃) a me nā kaomi kiʻekiʻe (ma luna o 10MPa). ʻO ke ʻano sila paʻakikī metala o ka triple eccentrickiwikā pepekehiki ke hoʻokō i ka leaka ʻole, e pale ana i ka hoʻonele ikehu a me nā pōʻino palekana i hoʻokumu ʻia e ka leaka mahu. I loko o ka ʻōnaehana desulfurization, hiki iā ia ke kū i ka ʻino ʻana o nā mea ʻino e like me ka slurry limestone.

2. ʻOihana petrochemical

He mea kūpono ia no nā paipu lawe o ka ʻaila maka, nā huahana ʻaila i hoʻomaʻemaʻe ʻia, a me nā mea maka kemika (e like me nā hopena waikawa a me alkali, nā mea hoʻoheheʻe organik), a me ka mana komo a me ka puka o nā ipu hana a me nā hale kiaʻi. No ka laʻana, ma nā kaapuni waena o nā paipu ʻaila maka mamao loa a me nā hale hana hoʻomaʻemaʻe a me nā kemika, hiki i ka valve butterfly flanged uila ʻekolu-offset ke hoʻololi i nā mea ʻino loa a me ka viscosity kiʻekiʻe. I kēia manawa, wehe a pani koke ia, e hiki ai ke ʻoki wikiwiki a hoʻoponopono paha i ke kahe waena e hōʻoia i ka hana mau a paʻa.

3. ʻOihana mālama wai

Me nā hana wai, nā hale hana hoʻomaʻemaʻe wai ʻino a me nā ʻōnaehana hoʻomaʻemaʻe wai ʻino ʻoihana. Hoʻohana ʻia ia i ka lawe ʻana i ka wai maʻemaʻe, ka hāpai ʻana i ka wai ʻino, ka hoʻohana hou ʻana i ka wai i hoʻihoʻi ʻia a me nā loulou ʻē aʻe, ʻoi aku hoʻi i nā paipu wai ʻino e loaʻa ana nā mea paʻa a me nā haumia. ʻO kona papa valve streamlined he haʻahaʻa ke kūʻē ʻana i ke kahe ʻana, ʻaʻole maʻalahi ke pani, a hiki i kona kūʻē ʻana i ka ʻaʻahu ke kū i ka ʻino ʻana o nā ʻāpana i loko o ka wai ʻino. Hiki i kāna hana sila ke pale i ka liki ʻana o ka wai ʻino a hoʻoulu i ka haumia lua.

4. ʻOihana hana hao

Hoʻohana ʻia ia i nā paipu kinoea umu pahū, nā paipu mahu hoʻololi, nā ʻōnaehana hoʻolulu wai hoʻolulu, nā paipu wehe lepo, a pēlā aku. Loaʻa i ke kinoea umu pahū ka lepo a me nā ʻāpana ʻino, a loli nui kona mahana. Hiki i ke sila paʻa a me ke ʻano pale ʻaʻahu o ka valve butterfly eccentric triple china ke hana paʻa no ka manawa lōʻihi. I kēia manawa, hiki i kāna hana pani wikiwiki ke hoʻoponopono i nā kūlana pilikia i ka hana metallurgical.

5. ʻEnekinia kūlanakauhale

Hoʻohana nui ʻia ia i nā paipu hoʻomehana kikowaena kūlanakauhale (wai wela wela kiʻekiʻe, mahu) a me nā paipu hoʻoili a me ka hāʻawi kinoea kūlohelohe. Pono nā paipu hoʻomehana e kū i nā mahana a me nā kaomi kiʻekiʻe, a he kiʻekiʻe loa nā koi sila no nā paipu kinoea kūlohelohe (e pale aku i nā pilikia leakage a me ka pahū). Hiki i nā valves butterfly ʻoihana ke kaulike i ka hilinaʻi sila a me ka maʻalahi o ka hana, a kūpono ia no nā koi hana lōʻihi o nā pūnaewele paipu kūlanakauhale.
