ʻO Ductile Iron/Cast Iron Material ED Series Wafer Butterfly Valve me ka Handlever i hana ʻia ma Kina
Wehewehena:
He ʻano lima palupalu ka kiwikā pulelehua ED Series Wafer a hiki ke hoʻokaʻawale i ke kino a me ka wai waena me ke ʻano pololei.
Nā Mea o nā ʻĀpana Nui:
| Nā ʻāpana | Mea Hana |
| Kino | CI,DI,WCB,ALB,CF8,CF8M |
| Pā | DI,WCB,ALB,CF8,CF8M, Disc i hoʻopaʻa ʻia i ka laholio, kila kila Duplex, Monel |
| Kumu | SS416,SS420,SS431,17-4PH |
| Noho | NBR, EPDM, Viton, PTFE |
| Pin Taper | SS416,SS420,SS431,17-4PH |
Ka Hoʻākāka Noho:
| Mea Hana | Mahana | Hoʻohana i ka wehewehe |
| NBR | -23℃ ~ 82℃ | ʻO Buna-NBR: (Nitrile Butadiene Rubber) he ikaika tensile maikaʻi a me ke kū'ē'ē i ka abrasion. He kūpa'a ho'i ia i nā huahana hydrocarbon. He mea lawelawe maika'i ia no ka ho'ohana'ana i ka wai, ka vacuum, ka waikawa, nā pa'akai, nā alkalines, nā momona, nā'aila, nā greases, nā'aila hydraulic a me ka ethylene glycol. 'A'ole hiki ke ho'ohana'ia'o Buna-N no ka acetone, ketones a me nā hydrocarbons nitrated a chlorinated paha. |
| Ka manawa pana-23 ℃ ~120 ℃ | ||
| EPDM | -20 ℃ ~ 130 ℃ | ʻO ka laholio EPDM laulā: he laholio synthetic lawelawe laulā maikaʻi i hoʻohana ʻia i ka wai wela, nā mea inu, nā ʻōnaehana huahana waiū a me nā mea i loaʻa nā ketones, ka waiʻona, nā nitric ether esters a me ka glycerol. Akā, ʻaʻole hiki ke hoʻohana ʻia ka EPDM no nā aila hydrocarbon, nā minelala a i ʻole nā mea hoʻoheheʻe. |
| Ka manawa pana-30 ℃ ~ 150 ℃ | ||
| ʻO Viton | -10 ℃ ~ 180 ℃ | He elastomer hydrocarbon fluorinated ʻo Viton me ke kūpaʻa maikaʻi loa i ka hapa nui o nā aila a me nā kinoea hydrocarbon a me nā huahana ʻē aʻe i hana ʻia ma ka petroleum. ʻAʻole hiki ke hoʻohana ʻia ʻo Viton no ka lawelawe mahu, ka wai wela ma luna o 82 ℃ a i ʻole nā alkali i hoʻohuihui ʻia. |
| PTFE | -5℃ ~ 110℃ | He kūpaʻa maikaʻi ka hana kemika o ka PTFE a ʻaʻole e pipili ka ʻili. I ka manawa like, he waiwai lubricity maikaʻi kona a me ke kūpaʻa ʻana i ka wā ʻelemakule. He mea maikaʻi ia no ka hoʻohana ʻana i nā waikawa, alkalis, oxidant a me nā mea ʻino ʻē aʻe. |
| (Palapala loko EDPM) | ||
| PTFE | -5℃~90℃ | |
| (NBR o loko) |
Hana:ka lever, ka pahu kia, ka mea hoʻoikaika uila, ka mea hoʻoikaika pneumatic.
Nā ʻano:
1. Hoʻolālā poʻo kumu o Double "D" a i ʻole Square cross: Kūpono e hoʻopili me nā actuators like ʻole, e hāʻawi i ka torque hou aku;
2. ʻElua ʻāpana mea hoʻokele huinahā kumu: Pili ka pilina ʻole i nā kūlana maikaʻi ʻole;
3. Kino me ka ʻole o ka hoʻolālā Frame: Hiki i ka noho ke hoʻokaʻawale i ke kino a me ka wai wai me ke ʻano pololei, a kūpono hoʻi me ka paipu flange.
