ʻO 6 mau hiʻohiʻona o nā kiwi kinipōpō plastik āu i ʻike ʻole ai

Hoʻokele ʻia ka ʻāpana wehe a pani ʻia (sphere) e ke kumu valve a hoʻololi a puni ke axis o ke kumu valve.Hoʻohana nui ʻia e ʻoki a hoʻopili paha i ka waena i ka pipeline, a hiki ke hoʻohana ʻia no ka hoʻoponopono ʻana i ka wai a me ka mana.Pono e hoʻokomo ʻia kēia ʻano valve ma ke ʻano ākea ma ka pipeline.

Nā hiʻohiʻona o ka plasticpāpaʻi kinipōpō paʻa:

(1) Ke kaomi hana kiʻekiʻe: hiki i ke kaomi hana o nā mea like ʻole ke hiki i 1.0Mpa i ka lumi wela.

(2) ʻO ka mahana hana ākea: ʻO ka mahana hana PVDF he -20 ℃ ~ + 120 ℃;ʻO ka mahana hana RPP he -20 ℃ ~ + 95 ℃;ʻO ka mahana hana UPVC -50 ℃ ~ + 95 ℃.

(3) Ke kū'ē i ka hopena maikaʻi: RPP, UPVC, PVDF, CPVC he kiʻekiʻe ka ikaika mechanical a me ka hopena hopena.

(4) Haʻahaʻa haʻahaʻa kahe kahe wai: laumania i loko o ka paia o ka huahana, liʻiliʻi friction coefficient, a kiʻekiʻe lawe lawe pono.

(5) ʻO nā waiwai kemika maikaʻi loa: ʻAʻohe mea ʻawaʻawa kēia huahana, ʻaʻala ʻole, ka waikawa a me ka alkali pale, pale ʻana i ka corrosion, a he nui nā noi.Hoʻohana nui ʻia ka PPR no ka meaʻai, nā mea inu, ka wai paila,

ʻO ka wai maʻemaʻe a me nā paipu wai ʻē aʻe a me nā mea pono me nā pono hoʻomaʻemaʻe hiki ke hoʻohana ʻia no nā paipu wai a me nā mea hana me ka corrosive haʻahaʻa;

Hoʻohana nui ʻia ʻo RPP, UPVC, PVDF, CPVC no ka holo ʻana o ka wai (gas) me nā waikawa corrosive ikaika, nā alkali ikaika a me nā ʻakika hui ʻia.

(6) Maikaʻi ka hoʻokomo ʻana a me ka maikaʻi o ka ea: he māmā kēia huahana i ke kaumaha, hoʻopaʻa ʻia a hoʻopaʻa ʻia paha, nā paipu piha piha, ka hana maʻalahi, ka ea maikaʻi, a me ka ikaika haʻahaʻa.

ʻO nā hiʻohiʻona koʻikoʻi o ka valve ball plastic kona ʻano paʻa, hoʻopaʻa paʻa pono, ʻano maʻalahi, a me ka mālama pono.Hoʻopili pinepine ʻia ka ʻili hoʻopaʻa a me ka spherical surface, ʻaʻole maʻalahi e hoʻopau ʻia e ka medium, a maʻalahi hoʻi e hana a mālama.He kūpono ia no ka wai, nā mea hoʻoheheʻe, nā waikawa a me ke kinoea maoli.He kūpono hoʻi ke ʻano hana no ka ʻenehana me nā kūlana hana koʻikoʻi, e like me ka oxygen, hydrogen peroxide, methane a me ethylene, etc., i hoʻohana nui ʻia i nā ʻoihana like ʻole.Hiki ke hoʻohui a hoʻohui ʻia ke kino kīpē pōpō.
