Wahi a ke ʻano pili flange, kakino valve leleua mahele nui ia i: wafer type A, wafer type LT, single flange, double flange, U type flange.
ʻO ka ʻano Wafer A ʻaʻole ia e pili ana i ka lua, ʻo LT type 24" ma luna o nā kikoʻī nui e hoʻohana pinepine i ka ikaika U-type valve kino e hana i ka pilina pili, pono e hoʻohana ka hopena o ka pipeline i ke ʻano LT.
E like me ke ano o ka sila, kakino valve lelehiki ke hoʻokaʻawale ʻia i ke kino vulcanized rubber (ke kino noho ʻole hiki ke hoʻololi ʻia), ke kino kīpē maʻemaʻe (maʻamau me ka noho kūpaʻa corrosion), a me ke kino noho hiki ke pani ʻia (me ka noho hope paʻa a me ka noho palupalu).
ʻO nā mea kino o kā mākou mea maʻamau i hoʻohana pinepine ʻia i nā kīwaha butterfly concentric ka mea nui: hao hao, hao ductile, kino kila kila, kino kila kila, kino keleawe, kino alumini a me ke kino kila super duplex.
Ka hao: ʻO ka mea maʻamau i loko o ka valve butterfly, hoʻohana nui ʻia i loko o ka ʻōnaehana wai, maʻalahi e ʻino ʻia, pōkole ke ola lawelawe, ʻuʻuku.
Ka hao hao: He kūpono ka hao no ke kaomi inoa PN ≤ 1.0MPa, ka mahana -10 ℃ ~ 200 ℃ o ka wai, ka mahu, ka ea, ke kinoea a me ka ʻaila a me nā mea hoʻolaha ʻē aʻe.ʻO nā maʻamau a me nā māka i hoʻohana pinepine ʻia ka hao hina hina: GB/T 12226, HT200, HT250, HT300, HT350.
ʻO ka hao Ductile: I ka hana ʻana o ka valve butterfly e hoʻohālikelike ʻia me ke kila kalapona kekahi mea, hoʻohana maʻamau i ka pipeline ʻōnaehana wai, akā i kēia manawa ʻo ka ʻōnaehana wai ma ka hoʻohana ʻana i kahi ākea ākea.
ʻO ka hao hao: He kūpono no ka PN ≤ 2.5MPa, ka mahana -30 ~ 350 ℃ wai, ka mahu, ka ea a me ka ʻaila a me nā mea ʻē aʻe.ʻO nā kūlana maʻamau a me nā māka: GB / T12227: 2005 QT400-15, QT450-10, QT500-7;EN1563 EN-GJS-400-15, ASTM A536,65 45-12, ASTM A395,65 45 12.
ʻO ke kila kalapona: Hiki ke hoʻohana ʻia i loko o ka ʻōnaehana wai, ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe kiʻekiʻe a me ke kūpaʻa ʻana o ka pahu kalapona kila, ʻoi aku ka nui o ka paʻa paʻa paʻa paʻa me nā mea hao kalapona.
ʻO ke kila kalapona: He kūpono no ke kaomi inoa PN ≤ 3.2MPa, ka mahana -30 ~ 425 ℃ wai, mahu, ea, hydrogen, ammonia, nitrogen a me nā huahana ʻaila a me nā mea ʻē aʻe.ʻO nā māka a me nā kūlana maʻamau ka ASTM A216/216M: 2018WCA, WCB, ZG25 a me ke kila kila kiʻekiʻe 20, 25, 30 a me ke kila kila haʻahaʻa 16MN.
ʻO ke kila kila: He maikaʻi loa ka ʻōpala a me ke kūpaʻa ʻana o nā kiwi lele, a ua hoʻohana nui ʻia i nā pipeline e pono ai i ka corrosion a me ka pale ʻana, a he kiʻekiʻe ke kumukūʻai.E pili ana i ke kaomi nominal PN ≤ 6.4.0MPa, ka wela wela: -268 ° C a + 425 ° C, hoʻohana pinepine ʻia i ka wai, kai, ʻoihana kemika, aila a me ke kinoea, lāʻau lapaʻau, meaʻai.Nā kūlana maʻamau a me nā māka: ASTM A351/351M:2018, SUS304,304, SUS316, 316
Copper alloy: Copper alloy butterfly valve he kūpono ia no ka PN ≤ 2.5MPa wai, kai, oxygen, ea, aila a me nā mea ʻē aʻe, a me ka media mahu ma kahi mahana o -40 ~ 250 ℃, i hoʻohana mau ʻia no ZGnSn10Zn2 (tin bronze. ), H62, Hpb59-1 (keleawe), QAZ19-2, QA19-4 (ke keleawe alumina).Nā kūlana maʻamau a me nā māka: ASTM B148:2014, UNS C95400, UNS C95500, UNS C95800;ASTM B150 C6300.
