ʻO ka pāpaʻi lepe Seal Butterfly
Paʻa Paʻa Paʻa Paʻa
Hana ʻia nā sila paʻa i ka metala, e like me nā ʻeke metala, nā apo metala, a me nā mea ʻē aʻe, a hiki ke hoʻopaʻa ʻia ma o ka hakakā ʻana ma waena o nā metala.No laila, ʻoi aku ka maikaʻi o ka hana sealing, akā ua hana ʻia kā mākou ZFA valvehoʻopaʻa paʻa paʻa paʻa triple eccentric butterfly valvehiki ke hoʻokō i ka leakage ʻole.Hana ʻia nā sila palupalu i nā mea elastic, e like me ka rubber, PTFE, a me nā mea ʻē aʻe.
ʻO nā ʻokoʻa ma waena o nā valve lele paʻa i hoʻopaʻa ʻia a me nā valve lele lele i hoʻopaʻa ʻia.
1. Nā ʻokoʻa i kūkulu ʻia: ʻO nā kiwipa lele lele ka hapa waena anā kīwī lele lele eccentric pālua, oiai paakiki sila peʻapeʻa kiwikā he hookahi eccentric papa kīwiʻi a mekiwikā lele lele ʻekolu.
2. Palena wela: Hoʻohana ʻia ke sila palupalu i ka ʻāina wela maʻamau, Rubber no -20 ℃ ~ + 120 ℃, PTFE no -25 ℃ ~ + 150 ℃.Hiki ke hoʻohana i ka sila paʻa i ka haʻahaʻa haʻahaʻa, ka mahana maʻamau, ka wela kiʻekiʻe a me nā wahi ʻē aʻe, LCB no -29 ° C -+180 ° C, WCB ≤425 ° C, Stainless Steel≤600 ° C.
3. Paʻa: Hiki ke hoʻohanaʻia ka sila palupalu haʻahaʻa haʻahaʻa-kaomi maʻamau PN6-PN25, hiki ke hoʻohanaʻia ke sila paʻakikī i nā kūlana kiʻekiʻe a me ke kiʻekiʻe e like me PN40 a ma luna.
4. Hoʻokō sila ʻana: ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana.Pākolukiwi lele lelehiki ke mālama i ka sila leakage maikaʻi maikaʻi ma ke kaomi kiʻekiʻe a me ke kaiapuni wela kiʻekiʻe.Eia nō naʻe, paʻakikī no nā kiwi lele lele paʻa paʻa maʻamau e hoʻokō i ka leakage ʻole.
5. Ke ola o ka lawelawe: Hoʻomaʻamaʻa ʻia nā kiwi lele lele paheʻe i ka ʻelemakule a me ka ʻaʻahu, a ua manaʻo ʻia e pōkole ko lākou ola lawelawe.He lōʻihi ke ola lawelawe ʻana o nā valve butterfly paʻa paʻa.
Ma ka nānā ʻana i nā hiʻohiʻona i luna, ua kūpono ke kikowaena butterfly valve no ka hoʻohana ʻana i ka wai maʻemaʻe, ka ʻilikai, ka wai kai, ka wai paʻakai, ka mahu, ke kinoea maoli, ka meaʻai, ka lāʻau lapaʻau, nā huahana ʻaila, ka wehe ʻana a me ka pani ʻana o ka ventila a me nā pipeline wehe lepo, a nā ʻakika like ʻole i ka mahana maʻamau, ke kaomi a me nā hiʻohiʻona media non-corrosive.Pono ka alkali a me nā pipeline ʻē aʻe i ka sila piha ʻana, ka hoʻāʻo ʻana i ka leakage gas, a me ka mahana hana o -10 ~ 150 ℃.ʻO ka valve butterfly paʻa i hoʻopaʻa ʻia he kūpono ia no nā hiʻohiʻona me ke kiʻekiʻe kiʻekiʻe, ke kaomi kiʻekiʻe a me ka media corrosive, e like me ka hoʻoponopono ʻana a me nā mea throttling i ka aila, gas, acid a me nā pipeline alkali e like me ka hoʻomehana ʻana o ke kūlanakauhale, ka hāʻawi ʻana i ke kinoea, ka lako wai, ka ʻaila, petrochemical, ʻoihana kemika, metallurgy, a me ka mana uila.a me nā kula ʻē aʻe.He pani maikaʻi ia no nā ʻīpuka puka a me nā kiwi honua.
