Sila palupalu o ka kiwikā pulelehua a me ke sila paʻakikī

1. He aha ka ʻokoʻa nui ma waena okiwikā pepeke sila palupalua me ka kiwikā pepeke sila paʻakikī?

He ʻokoʻa ke ʻano o ke apo sila. ʻO ke sila ʻelua o kahi valve pepeke palupalu he "noho metala + apo sila ʻaʻole metala", a ʻo nā mea i hoʻohana pinepine ʻia e komo pū me ka rubber (EPDM/NBR), polytetrafluoroethylene (PTFE), a pēlā aku, e like me ka mea i hōʻike ʻia ma ke Kiʻi 01; ʻo ke sila ʻelua o kahi valve pepeke paʻakikī he "metala i metala", a ʻo ka noho valve a me ka ʻili sila e hana pinepine ʻia me ke kila kila, ke kila alloy a i ʻole ka ʻili carbide. Hoʻokō ka mea mua i ke sila ʻana ma o ka hoʻololi elastic o ka mea, aʻo ka mea hope e hilinaʻi nei i ka mīkini kikoʻī a me ke kaomi waena e hoʻokō ai i ke sila ʻana.

2. He aha ka pae mahana kūpono no kēlā me kēia?

Ua kaupalena ʻia nā sila palupalu i nā mea ʻaʻole metala: kūpono ka laholio EPDM no -40℃~120℃, a hiki i ka PTFE ke hiki i -40℃~200℃. ʻAʻohe kapu no nā sila paʻakikī. Kūpono nā kiwikā pepeke sila paʻakikī kila kila maʻamau no -40℃~425℃, a hiki i nā mea hao kūikawā ke kū i nā mahana kiʻekiʻe ma luna o 600℃.

3. ʻO wai ka hana sila i ʻoi aku ka maikaʻi?

ʻOi aku ka maikaʻi o ke sila palupalu a hiki ke hoʻokō i ka leaka ʻole (ANSI Class VI). Hiki i ka elasticity o ka rubber/PTFE ke hoʻopiha i ka microscopic unevenness ma ka ʻili metala a hoʻokō i ka sila ʻana i ka pae pehu. Ma muli o ka pili paʻa o ka metala, ʻo nā koi maʻamau o nā sila paʻakikī he ANSI Class IV ~ V (ʻae ʻia ka leakage liʻiliʻi), kahi kūpono no nā media hana i loaʻa kahi hoʻomanawanui no ka leakage.

4. He aha ka ʻokoʻa ma waena o ke ola lawelawe a me nā kumukūʻai mālama?

ʻOi aku ka paʻa o nā sila paʻa. He maʻalahi ke komo ʻana a me ka ʻelemakule ʻana o ke apo sila palupalu/PTFE ma muli o ka ʻino lōʻihi a me ka hoʻololi pinepine ʻana. Pono e hoʻololi ʻia ke apo sila i kēlā me kēia 2 a 5 mau makahiki. Ma hope o ka pīpī ʻia ʻana o ka ʻili metala sila paʻa me ka carbide, kūpaʻa ia i ka ʻino a me ka ʻino, a he ola lawelawe ma mua o 10 mau makahiki. He kūpono ia no ka hoʻoponopono pinepine ʻana i nā kūlana hana. ʻOiai ke kiʻekiʻe o ke kumukūʻai mua, ʻoi aku ka haʻahaʻa o ke kumukūʻai mālama lōʻihi.

5. Pehea ka ʻokoʻa o ka hoʻololi ʻana o ka pāpāho?

ʻAʻole kūpaʻa ka sila palupalu i ka pala ikaika/mea hana i loaʻa nā ʻāpana. ʻOiai he kūpaʻa kemika maikaʻi ka laholio a me ka PTFE, inā loaʻa nā ʻāpana paʻakikī i loko o ka mea hana (e like me ka slurry, ka pauka lanahu), hiki i nā ʻāpana ke kahakaha maʻalahi i ka ʻili sila palupalu ke wehe ʻia a pani ʻia ka valve, e hoʻoulu ai i ka liki. He kūpono nā sila paʻakikī no nā kūlana hana koʻikoʻi e like me ka mahu wela kiʻekiʻe, nā huahana aila, nā slurries i loaʻa nā ʻāpana, a me nā kinoea kaomi kiʻekiʻe.

ʻO ka ʻokoʻa nui ma waena o ke sila palupalu a me ke sila paʻakikī okiwikā pepekeAia i loko o ka mea sila: he elasticity maikaʻi ko ke sila palupalu (rubber/PTFE), hiki ke hoʻokō i ka leakage ʻole, a kūpono no nā media maʻemaʻe i ka mahana o ka lumi; ʻo ke sila paʻakikī (metala i ka metala) he kūpaʻa i ka mahana kiʻekiʻe a kūpaʻa i ka ʻaʻahu, a kūpono no nā kūlana hana koʻikoʻi e like me ka mahu a me nā ʻāpana. Loaʻa i nā mea ʻelua ko lākou mau pono ponoʻī, a pono e kau ʻia ke koho ma muli o nā kūlana hana.ʻO Tianjin Tanggu Water-Seal Valve Co., Ltdloea i ka hana ʻana onā kiwikā pepeke, nā kiwikā puka, nā kiwikā nānāa me nā ʻano valve ʻē aʻe. Welina mai e kāhea mai iā mākou a e hāʻawi mākou iā ʻoe i nā manaʻo koho loea!
