Hoʻokele ʻia ka lālā wehe a pani ʻia (pōpō) e ke kumu valve a hoʻololi a puni ke koʻi o ke kumu valve.Hoʻohana nui ʻia e ʻoki a hoʻopili paha i ka waena i ka pipeline, hiki ke hoʻohana ʻia no ka hoʻoponopono ʻana i ka wai a me ka hoʻokele, pono e hoʻokomo ʻia kēia ʻano valve i ka pipeline maʻamau.
ʻO nā hiʻohiʻona pāpaʻi pōlele palaki:
(1) Ke kaomi hana kiʻekiʻe: hiki ke piʻi i ka 1.0Mpa ke kaomi hana o nā mea like ʻole i ka mahana maʻamau.
(2) ka wela hoʻohana ākea: ka hoʻohana ʻana o ka mahana PVDF -20 ℃ ~ + 120 ℃;ʻO ka mahana hana o RPP he -20 ℃ ~ + 95 ℃;ʻO ka mahana hana o UPVC he -50 ℃ ~ + 95 ℃.
(3) maikaʻi ka hopena hopena: RPP, UPVC, PVDF, CPVC he kiʻekiʻe ka ikaika mechanical a me ka hopena hopena.
(4) liʻiliʻi ke kahe o ka wai: ʻoluʻolu ka pā o loko o ka huahana, liʻiliʻi ka friction coefficient, ʻoi aku ka maikaʻi o ka lawe ʻana.
(5) hana kemika maikaʻi loa: ʻaʻohe mea ʻawaʻawa kēia huahana, ʻono ʻole, ka ʻakika a me ke kūpaʻa alkali, ke kūpaʻa corrosion, ka laulā o ka hoʻohana.Hoʻohana nui ʻia ka PPR no ka meaʻai, ka mea inu, ka wai paila,
ʻO ka wai maʻemaʻe a me nā paipu wai ʻē aʻe a me nā mea hana me nā koi hoʻomaʻemaʻe, hiki ke hoʻohana ʻia no nā pipeline wai a me nā mea hana me ka liʻiliʻi o ka corrosion;
Hoʻohana nui ʻia ʻo RPP, UPVC, PVDF, CPVC no ka kahe wai (gas) o ka waika ikaika, alkali ikaika a me ka waikawa hui pū me ka corrosive ikaika.
(6) hoʻokomo maʻalahi, hoʻopaʻa maikaʻi: māmā ka huahana i ka maikaʻi, ka hoʻohana ʻana i ka hoʻopaʻa ʻana a i ʻole ka hoʻopili ʻana, nā paipu piha piha, hana maʻalahi, sila maikaʻi, haʻahaʻa haʻahaʻa.
ʻO ka valve pōleʻa plastik ponoʻī nā hiʻohiʻona nui o ka hoʻolālā paʻa, hoʻopaʻa hilinaʻi, ʻano maʻalahi, mālama maʻalahi, hoʻopaʻa ʻana i ka ʻili a me ka spherical pinepine i loko o ka moku paʻa, ʻaʻole maʻalahi ka erosion, maʻalahi ka hana a me ka mālama ʻana, pili i ka wai, solvent, acid. a me ke kinoea, e like me ka hana maʻamau, akā kūpono no nā kūlana hana o ka media, e like me ka oxygen, hydrogen peroxide, methane a me ka ethylene, Hoʻohana nui ia i nā ʻoihana like ʻole.Hiki ke hoʻohui a hoʻohui ʻia ke kino kīpē pōpō.
