ʻO ka wili ʻana he ʻano hana hoʻopau maʻamau no ka hoʻopaʻa ʻana i ka ʻili o nā valves i ka hana hana. Hiki i ka wili ʻana ke hoʻonui i ka pololei o ke kūlana kiʻekiʻe, ke ʻano geometric a me ka ʻili o ka ʻili, akā ʻaʻole hiki ke hoʻomaikaʻi i ka pololei o ke kūlana ma waena o nā ʻili o ka ʻili. ʻO ka nui o ka pololei o ka honua valve sealing surface he 0.001 ~ 0.003mm; ʻO ka pololei o ke ʻano geometric (e like me ka like ʻole) he 0.001mm; ka roughness ili he 0.1 ~ 0.008.
ʻO ke kumumanaʻo kumu o ka sealing surface grinding e pili ana i ʻelima mau ʻaoʻao: ke kaʻina wili, ka neʻe ʻana o ka wili, ka wikiwiki wili, ke kaomi wili a me ka ʻae ʻana.
1. Kaʻina wili
Hoʻohui maikaʻi ʻia ka mea wili a me ka ʻili o ke apo sealing, a ʻo ka mea wili e hana i nā neʻe wili paʻakikī ma ka ʻili hui. Hoʻokomo ʻia nā abrasive ma waena o ka mea hana lapping a me ka ʻili o ke apo hoʻopaʻa. Ke neʻe ka mea paahana a me ka ʻili o ke apo hoʻopaʻa paʻa i kekahi i kekahi, e paheʻe a ʻōwili ʻia kekahi hapa o nā ʻāpana abrasive i loko o ka abrasive ma waena o ka mea paahana a me ka ʻili o ke apo hoʻopaʻa. papa metala. ʻO nā piko ma luna o ka ʻili o ke apo hoʻopaʻa e hoʻopaʻa mua ʻia, a laila e hoʻokō mālie ʻia ka geometry i koi ʻia.
ʻO ka wili ʻana ʻaʻole ia he kaʻina hana mechanical o nā abrasives ma nā metala, akā he hana kemika kekahi. Hiki i ka momona i loko o ka abrasive ke hana i kahi kiʻiʻoniʻoni oxide ma luna o ka ʻili e hana ʻia, pēlā e wikiwiki ai i ka hana wili.
2 . wili ʻana
I ka neʻe ʻana o ka mea wili a me ka ʻili o ke apo sealing e pili ana i kekahi i kekahi, ʻo ka huina o nā ala hoʻoheheʻe pili o kēlā me kēia kiko ma luna o ka ʻili o ke apo hoʻopaʻa i ka mea hana wili e like. Eia kekahi, pono e hoʻololi mau ke kuhikuhi o ka neʻe pili. ʻO ka hoʻololi mau ʻana o ka ʻaoʻao o ka neʻe ʻana e pale i kēlā me kēia palaoa abrasive mai ka hana hou ʻana i kāna alahele ponoʻī ma luna o ka ʻili o ke apo hoʻopaʻa, i ʻole e hoʻokumu i nā hōʻailona ʻaʻahu a hoʻonui i ka roughness o ka ʻili o ke apo sealing. Eia kekahi, ʻaʻole hiki i ka hoʻololi mau ʻana o ke kuhikuhi o ka neʻe ʻana ke hoʻomāhele like ʻia ka abrasive, i hiki ke ʻoki ʻia ka metala ma ka ʻili o ke apo sealing.
ʻOiai paʻakikī ka neʻe ʻana o ka wili a hoʻololi nui ke ʻano o ka neʻe ʻana, e hana mau ʻia ka neʻe ʻana o ka wili ma ka ʻili hoʻopaʻa o ka mea wili a me ka ʻili o ke apo sealing. ʻO ka wili lima a i ʻole ka mīkini mīkini, ʻo ka pololei o ke ʻano geometric o ka ʻili apo sealing e pili nui ʻia e ka pololei geometric o ka mea wili a me ka neʻe ʻana.
3. wili māmā
ʻOi aku ka wikiwiki o ka wili ʻana, ʻoi aku ka maikaʻi o ka wili. ʻO ka wikiwiki o ka wili ʻana, ʻoi aku ka nui o nā ʻāpana abrasive e hele i ka ʻili o ka mea hana i kēlā me kēia manawa, a ʻoi aku ka nui o nā metala i ʻoki ʻia.
ʻO ka wikiwiki o ka wili ʻana he 10 ~ 240m / min. No nā mea hana e koi ana i ka pololei wili kiʻekiʻe, ʻaʻole ʻoi aku ka wikiwiki o ka wili ʻana ma mua o 30m/min. ʻO ka wikiwiki o ka wili ʻana o ka ili hoʻopaʻa o ka valve e pili ana i ka mea o ka ʻili hoʻopaʻa. ʻO ka wikiwiki o ka wili o ka ili o ke keleawe a me ka hao hao he 10 ~ 45m / min; ʻo ka ili hoʻopaʻa o ke kila paʻakikī a me ka paʻakikī paʻakikī he 25 ~ 80m / min; ka sila ili o austenitic kuhiliʻole kila 10 ~ 25m / min.
4. kaomi wili
Hoʻonui ka hana wili me ka piʻi ʻana o ke kaomi wili, a ʻaʻole pono ke kiʻekiʻe ke kiʻekiʻe o ka wili, maʻamau 0.01-0.4MPa.
I ka wili ʻana i ka ʻili o ka hoʻoheheʻe ʻana i ka hao, ke keleawe a me ka austenitic stainless steel, ʻo ke kaomi wili he 0.1 ~ 0.3MPa; ʻO ka ili hoʻopaʻa o ke kila paʻakikī a me ka paʻakikī paʻakikī he 0.15 ~ 0.4MPa. E lawe i ka waiwai nui no ka wili ʻana a me ka waiwai liʻiliʻi no ka wili maikaʻi.
5. Hāʻawi wili
ʻOiai ʻo ka wili ʻana he hana hoʻopau, liʻiliʻi loa ka nui o ka ʻoki ʻana. ʻO ka nui o ka haʻawina wili e pili ana i ka pololei o ka mīkini a me ka ʻili o ka ʻili o ke kaʻina hana mua. Ma lalo o ka manaʻo o ka hōʻoia ʻana i ka wehe ʻana i nā ʻāpana hana o ke kaʻina hana mua a me ka hoʻoponopono ʻana i ka hewa geometric o ke apo sealing, ʻoi aku ka liʻiliʻi o ka ʻāpana wili, ʻoi aku ka maikaʻi.
Pono e wili ʻia ka ʻili o ka sila ma mua o ka wili ʻana. Ma hope o ka wili maikaʻi ʻana, hiki ke hoʻopili pololei ʻia ka ʻili o ka sila, a ʻo ka haʻahaʻa haʻahaʻa haʻahaʻa: ʻo ke anawaena he 0.008 ~ 0.020mm; ʻO ka haʻawina mokulele he 0.006 ~ 0.015mm. E lawe i kahi waiwai liʻiliʻi ke kiʻekiʻe ka wili lima a i ʻole ka paʻakikī o nā mea, a e lawe i ka waiwai nui inā haʻahaʻa ka wili mīkini a i ʻole ka paʻakikī.
ʻAʻole maʻalahi ka ʻili ʻana o ka ʻili o ke kino valve i ka lepo a hana ʻia, no laila hiki ke hoʻohana ʻia ka huli ʻana. Ma hope o ka huli ʻana, pono ka ʻili o ka hoʻopaʻa ʻana ma mua o ka hoʻopau ʻana, a ʻo ka haʻawina mokulele he 0.012 ~ 0.050mm.
ʻO Tianjin tanggu wai-seal valve Co., ltd i kikoʻī ʻia i ka hana ʻanakiwi lele lele noho kūpale, kiwi puka, Y-strainer, pahu kaulike, wafer check valve, etc.
