ʻO ka Ductile Iron Soft Seal Gate Valve VS. ʻO ka Ductile Iron Hard Seal Gate Valve
ʻO nā kiwikā puka sila palupalu a me nā kiwikā puka sila paʻakikī he mau mea hana maʻamau no ka hoʻoponopono ʻana a me ka pale ʻana i ke kahe ʻana, he hana sila maikaʻi ko lāua ʻelua, he ākea ka hoʻohana ʻana, a ʻo ia kekahi o nā huahana a nā mea kūʻai aku e kūʻai pinepine aku ai. Hiki i kekahi poʻe kūʻai novice ke hoihoi, e like me ka kiwikā puka, he aha ka ʻokoʻa ma waena o lākou?
ʻO ka sila palupalu he sila ma waena o ka metala a me ka mea ʻole-metala, ʻoiai ʻo ka sila paʻakikī he sila ma waena o ka metala a me ka metala. ʻO ka valve puka sila palupalu a me ka valve puka sila paʻakikī he mau mea sila, ua hana pololei ʻia ka sila paʻakikī me ka mea noho e hōʻoia i ka pololei o ke kūpono me ka spool (pōpō), ʻo ia hoʻi ke kila kila a me ke keleawe. Hoʻokomo ʻia ka sila palupalu i loko o ka mea sila noho valve he mea ʻole-metala, ma muli o ka mea sila palupalu he kekelē o ka elasticity, a no laila ʻoi aku ka haʻahaʻa o nā koi kikoʻī hana ma mua o ka sila paʻakikī. Ma lalo nei e lawe iā ʻoe e hoʻomaopopo i ka ʻokoʻa ma waena o ka valve puka sila palupalu a me ka valve puka sila paʻakikī.
Nā mea sila mua
1. He ʻokoʻa nā mea sila ʻelua. ʻO ka valve puka sila palupalu he laholio a PTFE paha a me nā mea ʻē aʻe. ʻO ka valve puka sila paʻa e hoʻohana ana i ke kila kila a me nā metala ʻē aʻe.
2. Sila palupalu: ke sila ʻana i ka ʻaoʻao hope o nā ʻaoʻao ʻelua o kahi mea metala, ʻo kēlā ʻaoʻao o nā mea metala ʻole elastic, i kapa ʻia ʻo "sila palupalu". ʻO ka hopena sila o ia mau valves puka, akā ʻaʻole kiʻekiʻe ke kiʻekiʻe o ka mahana, maʻalahi ke komo a haehae, a me nā waiwai mechanical maikaʻi ʻole. E like me ke kila + rubber; kila + PTFE a pēlā aku.
3. Sila paʻa: ʻO ka sila paʻa a me ka sila ʻana ma nā ʻaoʻao ʻelua he metala a i ʻole nā mea paʻa ʻē aʻe. ʻO kēlā sila ʻana o ka valve puka he maikaʻi ʻole ia, akā he kūpaʻa wela kiʻekiʻe, kūpaʻa ʻaʻahu, a he maikaʻi nā waiwai mechanical. E like me ke kila + kila; kila + keleawe; kila + graphite; kila + alloy kila; (hiki ke hoʻohana i ka hao hoʻolei, kila alloy, pena pena, a pēlā aku).
ʻO ka lua, ke kaʻina hana kūkulu
He ʻano hana paʻakikī ko ka ʻoihana mīkini, he nui o ia mau mea he haʻahaʻa loa ka mahana a me ke kaomi haʻahaʻa, ke kūpaʻa kiʻekiʻe o ka pāpāho, a me ka ʻino. I kēia manawa, ua alakaʻi ka holomua ʻenehana i ka hoʻolaha ʻana o nā kiwikā puka sila paʻa.
I mea e noʻonoʻo ai i ka pilina ma waena o ka paʻakikī o ka metala, ka valve puka sila paʻakikī, a me ka sila palupalu, pono e hoʻopaʻakikī ʻia ke kino valve, a pono e hoʻomau i ka wili ʻana i ka papa valve a me ka noho valve e hoʻokō i ke sila ʻana. ʻOi aku ka lōʻihi o ke kaʻina hana valve puka sila paʻakikī.
ʻO ke kolu, ka hoʻohana ʻana i nā kūlana
1, hiki i ka sila palupalu ke hoʻomaopopo i ka leaka ʻole, hiki ke hoʻoponopono ʻia ka sila paʻakikī e like me nā koi o ke kiʻekiʻe a me ka haʻahaʻa;
2. Hiki i nā sila palupalu ke liki ma lalo o nā mahana kiʻekiʻe, pono e makaʻala i ka pale ʻana i ke ahi, a ʻaʻole e liki nā sila paʻakikī ma lalo o nā mahana kiʻekiʻe. Hiki ke hoʻohana ʻia kahi sila paʻakikī pani pilikia i ke kaomi kiʻekiʻe, ʻaʻole hiki ke hoʻohana ʻia ka sila palupalu.
3, no kekahi mau mea ʻinoʻino, ʻaʻole hiki ke hoʻohana ʻia ka sila palupalu, hiki iā ʻoe ke hoʻohana i ka sila paʻakikī;
4, i ka mahana haʻahaʻa loa, e loaʻa ka leakage o ka mea sila palupalu, ʻaʻole ia he pilikia o ka sila paʻakikī;
ʻO ka hā, ke koho ʻana i nā lako
Hiki i nā pae sila ʻelua ke piʻi i ʻeono, ma muli o ke kaʻina hana, ka mahana, a me ke kaomi e koho ai i ka valve puka kūpono. No ka media maʻamau e loaʻa ana nā ʻāpana paʻa a i ʻole ka abrasive, a i ʻole ke piʻi aʻe ka mahana ma mua o 200 degere, ʻoi aku ka maikaʻi o ke koho ʻana i kahi sila paʻa. Inā nui ka torque o ka valve pani, pono ʻoe e koho e hoʻohana i kahi valve puka sila paʻa.
ʻElima, ka ʻokoʻa o ke ola lawelawe
ʻO ka pōmaikaʻi o ke sila palupalu he sila maikaʻi ia, ʻo ka hemahema, he maʻalahi ke ʻelemakule, ʻaʻahu a haehae, a he ola pōkole. ʻOi aku ka lōʻihi o ke ola lawelawe sila paʻa, a ʻoi aku ka maikaʻi ʻole o ka hana sila ma mua o ke sila palupalu, hiki i nā mea ʻelua ke hoʻokō kekahi i kekahi.
ʻO ka mea i luna aʻe ka ʻokoʻa ma waena o ka valve puka sila palupalu a me ka kaʻana like ʻana i ka ʻike valve puka sila paʻakikī, ke manaʻolana nei au e hiki iaʻu ke kōkua iā ʻoe i ka hana kūʻai.
