ʻO PVC (polyvinyl chloride) a me UPVC (unplasticized polyvinyl chloride) i hoʻohana nui ʻia i nā mea hana i ka hana ʻana i nā ʻano kīwī like ʻole.

ʻO PVC (polyvinyl chloride) a me UPVC (unplasticized polyvinyl chloride) i hoʻohana nui ʻia i nā mea hana i ka hana ʻana i nā ʻano kīwī like ʻole. Ua ʻike ʻia kēia mau mea no ko lākou lōʻihi, ke kūpaʻa ʻana i ka corrosion, a me ka hiki ke kūʻai aku, e hana ana iā lākou i mau koho kaulana no ka nui o nā noi. ʻO kekahi o nā mea hoʻohana maʻamau i hana ʻia mai ka PVC a me ka UPVC ʻo ia ka valve butterfly.

Hoʻokumu ʻia ke kumu hana o ka valve butterfly PVC ma kahi hoʻolālā maʻalahi akā pono. Aia kēia ʻano valve me kahi diski, i ʻike ʻia ʻo "butterfly," i hoʻonoho ʻia i waenakonu o ka paipu. Hoʻopili ʻia ka diski i kahi koʻokoʻo a i ʻole ka lāʻau e hoʻonui i waho o ka valve, e ʻae ai i ka hana manual a i ʻole ka hana automated.

I ka wā i pani ʻia ai ka valve, kū pololei ka diski i ke kahe o ka wai, me ka pale pono ʻana i ke ala o ka media. ʻO ka mea ʻē aʻe, ke kū ka valve i kahi ākea, ua like ka disc me ke kahe, e ʻae ana i ka hele ʻole ʻana o ka wai. ʻO kēia mīkini maʻalahi e hiki ai ke hoʻomalu wikiwiki a pololei i ke kahe, e hana ana i nā valve butterfly PVC i kūpono i nā ʻano o nā noi.

ʻO ka hoʻohana ʻana i nā mea PVC a me UPVC i ke kūkulu ʻana i nā kīwaha butterfly hāʻawi i nā pono he nui. Kūleʻa kēia mau mea i ka corrosion, e hoʻohana pono iā lākou no ka hoʻohana ʻana i nā noi kahi e hoʻopili ai ka valve me ka media aggressive a corrosive. Eia kekahi, he māmā a maʻalahi hoʻi ka PVC a me ka UPVC e hoʻokomo, e hana ana iā lākou i kumu kūʻai kūpono no nā noi ʻoihana a me nā ʻoihana.

Eia kekahi, ua ʻike ʻia nā kīwaha lele PVC a me UPVC no ko lākou mau haʻahaʻa haʻahaʻa haʻahaʻa a me ka lōʻihi o ke ola lawelawe, e hana ana iā lākou i koho hilinaʻi no nā ʻōnaehana hoʻokele wai. Loaʻa kēia mau valve i nā ʻano nui a me nā hoʻonohonoho e kūpono i nā koi kahe a me nā pono hoʻonohonoho.

I ka hopena, ʻo PVC a me UPVC butterfly valves he mau mea koʻikoʻi i loko o nā ʻōnaehana hoʻokele wai, e hāʻawi ana i ka mana kahe pono a maikaʻi. ʻO kā lākou kumu hana maʻalahi a maikaʻi hoʻi, i hui pū ʻia me nā pono o nā mea PVC a me UPVC, lilo lākou i koho kaulana no ka nui o nā noi i loko o nā ʻoihana e like me ka mālama wai, ka hana kemika, a me nā ʻōnaehana HVAC.
