Nui nā ʻano valves, akā ʻo ka hana maʻamau ka mea like, ʻo ia hoʻi, e hoʻohui a ʻoki paha i ke kahe waena. No laila, koʻikoʻi ka pilikia o ka hoʻopaʻa ʻana o ka valve.
No ka hōʻoia ʻana e hiki i ka valve ke ʻoki i ke kahe waena me ka ʻole o ka leakage, pono e hōʻoia i ka paʻa ʻana o ka sila valve. Nui nā kumu no ka leaka ʻana o ka valve, me ka hoʻolālā hoʻolālā kūpono ʻole, ka ʻili pili pili i ka sila, nā ʻāpana hoʻopaʻa wehe, ʻae ʻole ma waena o ke kino valve a me ka pāpale, a pēlā aku. ʻAe, pēlā e hana ai i kahi pilikia leak. No laila, he ʻenehana koʻikoʻi e pili ana i ka hana valve a me ka maikaʻi o ka valve sealing technology, a koi i ka noiʻi ʻōnaehana a hohonu.
ʻO nā mea hoʻopaʻa maʻamau i hoʻohana ʻia no nā valves ka nui o nā ʻano penei:
1. NBR
ʻO ke kūpaʻa ʻaila maikaʻi, ke kūpaʻa ʻaʻahu kiʻekiʻe, ke kūpaʻa wela maikaʻi, ka adhesion ikaika. ʻO kona mau hemahema ʻo ia ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa kūʻē, maikaʻi ʻole ka ozone kūʻē, maikaʻi ʻole nā waiwai uila, a haʻahaʻa iki ka elasticity.
2. EPDM
ʻO ka hiʻohiʻona koʻikoʻi o ka EPDM ʻo ia kona kūpaʻa oxidation kiʻekiʻe, ka pale ozone a me ke kūpaʻa corrosion. No ka mea nona ka EPDM i ka ʻohana polyolefin, loaʻa iā ia nā hiʻohiʻona vulcanization maikaʻi loa.
3. PTFE
He ikaika ko ka PTFE, ke kū'ē i ka nui o nā aila a me nā mea ho'ohehe'e (koe na ketones a me nā esters), ke kū'ē i ka wā maika'i a me ke kū'ē o ka ozone, akā maika'i ke kūpa'a anu.
4. Ka hao hao
Hoʻomaopopo: Hoʻohana ʻia ka hao hao no ka wai, ke kinoea a me ka ʻaila ʻaila me ka mahana o≤100°C a me ke kaomi inoa o≤1.6mpa.
5. ʻO ka huila nikela
Hoʻomaopopo: Hoʻohana ʻia nā mea hoʻoheheʻe Nickel no nā pipeline me kahi mahana o -70 ~ 150°C a me kahi kaomi ʻenekinia PN≤20.5mpa.
6. Aleki keleawe
He kūpaʻa maikaʻi ka ʻaʻahu keleawe a kūpono i ka wai a me nā paipu mahu me ka mahana≤200℃a me ke kaomi inoa PN≤1.6mpa.
