Kiwikā Pepeiao Sila Palupalu
Pākuʻi Pepeiao Sila Paʻakikī
Hana ʻia nā sila paʻa i ka metala, e like me nā gaskets metala, nā apo metala, a pēlā aku, a hoʻokō ʻia ke sila ʻana ma o ka friction ma waena o nā metala. No laila, ʻaʻole maikaʻi ka hana sila ʻana, akā hiki i kā mākou valve ZFA i hana ʻia me ka multi-layer hard seal triple offset butterfly valve ke hoʻokō i ka leakage ʻole. Hana ʻia nā sila palupalu me nā mea elastic, e like me ka rubber, PTFE, a pēlā aku. No kekahi mau mea me ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe, ʻaʻole hiki ke hoʻokō i nā koi hana, hiki i nā valves butterfly paʻa ke hoʻoponopono i ka pilikia.
ʻO nā ʻokoʻa ma waena o nā kiwikā pepeke paʻa-paʻa a me nā kiwikā pepeke palupalu-paʻa:
1. Nā ʻokoʻa kūkulu: ʻO nā kiwikā pepeke sila palupalu he mau kiwikā pepeke waena anā kiwikā pulelehua eccentric pālua, ʻoiai ʻo nā kiwikā pepeke sila paʻakikī he mau kiwikā pepeke eccentric hoʻokahi anā kiwikā pulelehua eccentric ʻekolu.
2. Ke kūpaʻa ʻana i ka mahana: Hoʻohana ʻia ka sila palupalu i kahi mahana maʻamau, ʻo ka laholio no -20℃~+120℃, ʻo PTFE no -25℃~+150℃. Hiki ke hoʻohana ʻia ka sila paʻakikī i ka mahana haʻahaʻa, ka mahana maʻamau, ka mahana kiʻekiʻe a me nā wahi ʻē aʻe, ʻo ke kino kiwikā pepeke LCB no -29°C -+180°C, ʻo ke kino kiwikā pepeke WCB ≤425°C, ʻo ke kino kiwikā pepeke kila kila ≤600°C.
3. Kaomi: Sila palupalu haʻahaʻa haʻahaʻa-kaomi maʻamau PN6-PN25, hiki ke hoʻohana ʻia ke sila paʻakikī i nā kūlana kaomi waena a me ke kiʻekiʻe e like me PN40 a ma luna.
4. Hana sila: ʻOi aku ka maikaʻi o ka hana sila ʻana o ka valve butterfly sila palupalu a me ka valve butterfly sila paʻakikī triple offset. Hiki i ka valve butterfly eccentric ʻekolu ke mālama i ka sila leaka ʻole maikaʻi i ke kaomi kiʻekiʻe a me ke kaiapuni wela kiʻekiʻe. Eia nō naʻe, he paʻakikī no nā valves butterfly paʻakikī maʻamau ke hoʻokō i ka leaka ʻole.
5. Ola lawelawe: He maʻalahi nā kiwikā pepeke palupalu i ka ʻelemakule a me ke komo ʻana, a ua manaʻo ʻia he pōkole ko lākou ola lawelawe. He lōʻihi ke ola lawelawe o nā kiwikā pepeke paʻa.
Ma muli o nā ʻano i luna, kūpono ka valve butterfly centerline no ka hoʻohana ʻana i ka wai maʻemaʻe, ka wai ʻino, ka wai kai, ka wai paʻakai, ka mahu, ke kinoea kūlohelohe, ka meaʻai, ka lāʻau lapaʻau, nā huahana petroleum, ka wehe ʻana a me ka pani ʻana o nā paipu ea a me ka wehe ʻana i ka lepo, a me nā waikawa like ʻole i nā kūlana mahana, kaomi a me nā media corrosive ʻole. Pono nā pipeline Alkali a me nā pipeline ʻē aʻe i ka sila piha, ka hoʻāʻo leaka ʻole kinoea, a me ka mahana hana o -10 ~ 150 ℃. Kūpono ka valve butterfly paʻa no nā kūlana me ke kiʻekiʻe o ka mahana, ke kaomi kiʻekiʻe a me nā media corrosive, e like me nā mea hoʻoponopono a me nā mea hoʻoluliluli i nā pipeline aila, kinoea, waikawa a me alkali e like me ka hoʻomehana kūlanakauhale, ka lako kinoea, ka lako wai, ka petroleum, ka petrochemical, ka ʻoihana kemika, ka metallurgy, a me ka mana uila. a me nā kahua ʻē aʻe. He pani maikaʻi ia no nā valves puka a me nā valves globe.
