Pehea e koho ai i ka ponokīwī pēpē limamea sila?
ʻO nā valve butterfly manual kahi ʻano valve maʻamau, i hoʻohana nui ʻia no ka hoʻoponopono kahe a me ka hoʻokele wai i nā pipeline. He mea koʻikoʻi ka mea sealing i ka hana sila ʻana o ka valve butterfly manual, no laila ke koho ʻana i ka valve, pono e hoʻomaopopo i ka hana a me ka hoʻohana ʻana o nā mea hoʻopaʻa like ʻole i mea e koho ai i ka mea hoʻopaʻa lima butterfly valve sealing pono.
1. ʻO ka lāʻau fluorine (FKM)
Loaʻa i ka lāʻau Fluorine ke kūpaʻa kemika maikaʻi a me nā waiwai wela kiʻekiʻe, a hiki ke hana i kahi sila ʻoi aku ka maikaʻi ma nā haʻahaʻa haʻahaʻa. He kūpono no ka media wai e loaʻa ana i nā waikawa, nā alkalis, nā aila a me nā oxidants. Eia nō naʻe, ʻoi aku ke kumukūʻai o ka mea hoʻopaʻa paʻa fluorine a ʻaʻole kūpono no ka hoʻohana ʻana ma lalo o nā kūlana mahu.
2.NBR pulupulu
ʻO nā mea maikaʻi o ka NBR rubber sealing material he haʻahaʻa haʻahaʻa a me ka hana paʻa. Eia nō naʻe, ʻo kona kūpaʻa wela kiʻekiʻe, ke kūpaʻa o ka oxidation a me ke kūpaʻa corrosion he nāwaliwali, ʻoi aku ka maikaʻi no nā noi haʻahaʻa liʻiliʻi a me ka liʻiliʻi e like me ka wai, ka aila, ka mahu a me ka brine metala.
3. ʻAha Neoprene (CR)
Loaʻa i ka Neoprene ke kūpaʻa aila maikaʻi a me nā waiwai anti-kahiko, a hiki ke hoʻohana ʻia ma luna o kahi ākea ākea. He kūpono no ka aila, kalapona chlorinated a me nā mea hoʻoheheʻe ʻē aʻe, akā ʻaʻole kūpono no ke kaiapuni mahu.
4. Rubber Silicone (Si)
ʻO nā mea hoʻopaʻa hoʻopaʻa silicone he maikaʻi ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka radiation a me ka haʻalulu a me ke kūʻē ʻana, kūpono no ke sila ʻana i ke kaiapuni kiʻekiʻe. Eia nō naʻe, ʻo ka elasticity a me ka haʻalulu waimaka o ka silicone rubber ma ka haʻahaʻa haʻahaʻa haʻahaʻa he ʻilihune.
5.PTFE
ʻO ka pōmaikaʻi o ka PTFE ʻo ia ka maikaʻi o ka corrosion resistance a me ke kiʻekiʻe o ka wela, akā maikaʻi ʻole kona elasticity a me ke kūpaʻa ʻaʻahu, ʻaʻole kūpono ia no ka hoʻohana ʻana i nā wahi wai me nā kahe wikiwiki.
6. Polyimide (PI)
ʻO ka Polyimide kahi ʻano mea wela kiʻekiʻe a me ka ikaika kiʻekiʻe, me ka hana maikaʻi i ka wela kiʻekiʻe a me ke kūpaʻa ʻana i ka corrosion kemika maikaʻi loa, kūpono no ka wela kiʻekiʻe a me ke kaiapuni kiʻekiʻe e like me ka mea hoʻopaʻa.
Ke koho ʻana i kahi mea e hoʻopaʻa ai i ka valve butterfly manual, pono ia e noʻonoʻo i ke ʻano o ka wai i loko o ka pipeline, ka kahe kahe, ka mahana, ke kaomi a me nā mea ʻē aʻe, a koho i ka mea hoʻopaʻa paʻa kūpono e hōʻoia i ka hana paʻa a me ka hana palekana o ka manual. lele lele. He mea nui ia e hoʻomaopopo ma mua o ka hoʻohana ʻana i kekahi mea hoʻopaʻa paʻa, ʻōlelo ʻia e hoʻāʻo i kona kūpaʻa a me ka hoʻopaʻa ʻana i ka hana i loko o ke kaiapuni wai.
