1. Hoʻohālikelike Valve ʻO nā ʻano like ʻole Valve, me ka hoʻomaikaʻi mau ʻana o nā ʻano o nā pūʻulu piha o ka holo ʻana o nā lako hana a me ka hana, ke hoʻonui mau nei nā ʻano valve, a aia nā ʻano ʻano hoʻohālikelike.
1, e like me ka hoʻokaʻawale ʻokoʻa a me ka hoʻokele
(1) Ke hilinaʻi nei nā valve aunoa i ka hiki o ka mea waena (wai, ea, mahu, a me nā mea'ē aʻe) e hana iā ia iho, e like me nā valves palekana, nā pahu hoʻopaʻa, nā pahu hoʻohaʻahaʻa hoʻohaʻahaʻa, nā pahele mahu, nā pahele ea, kaʻoki pilikia. nā kiwikā, etc.
(2) Hoʻohana ʻia ʻo Valve valve e ka lima, uila, hydraulic a i ʻole pneumatic. E like me ka valve puka, ka valve globe, ka valve throttle, ka valve butterfly, ka valve ball, ka valve plug, etc.
2. Hoʻokaʻawale ma ka hoʻohana a me ka hana
(1) hoʻohana nui ʻia ka valve truncation e ʻoki a hoʻopili i ke kahe waena i ka pipeline. E like me ka valve honua, ka valve puka, ka valve ball, ka valve plug, ka valve butterfly, ka valve diaphragm, etc.
(2) Hoʻohana ʻia nā kiwi hōʻoia e pale i ka hoʻihoʻi ʻana o ka media. E like me nā ʻano hana like ʻole o ka valve check.
(3) Hoʻohana nui ʻia nā valve hoʻoponopono e hoʻoponopono i ke kaomi a me ke kahe o ka medium pipeline. E like me ka hoʻoponopono valve, throttle valve, hōʻemi i ka valve a pēlā aku.
(4) Hoʻohana ʻia ka valve shunt e hoʻololi i ke ʻano o ke kahe o ka medium i ka pipeline, a hoʻokani i ke kuleana o ka hāʻawi ʻana, shunt a i ʻole ka hui ʻana i ka medium. E like me ke ʻano o ke ʻano o ka hoʻokaʻawale ʻana i ka valve, tee a i ʻole ka moa ala ʻehā, tee a i ʻole ʻehā ʻaoʻao pōlele valve, nā ʻano pahele like ʻole.
(5) hoʻohana ʻia ka valve palekana no ka pale ʻana i ka palekana o ka overpressure, ka hoʻokuʻu ʻana o ka media keu, e pale i ke kaomi mai ka ʻoi aku o ka waiwai i kuhikuhi ʻia. E like me nā ʻano ʻano ʻokoʻa palekana palekana.
(6) Hoʻohana ʻia nā kīwī multi-purpose e hoʻololi i ʻelua, ʻelua a ʻoi aku paha nā ʻano o nā valve, e like me ka hoʻomaha ʻana i nā kiwi hoʻopaʻa, e nānā i nā kiwi pōpō, e hoʻōki i nā valve palekana, etc.
(7) ʻO nā kiwi kūikawā ʻē aʻe e like me ka valve blowdown, blowoff valve, coke clearing valve, pigging valve emergency cut-off valve, etc.
3, e like me ka hoʻohālikelike ʻenehana nui
1. Hoʻokaʻawale ʻia e ka nui inoa
(1) liʻiliʻi anawaena valve nominal size DN≤40mm, ka valve.
(2) ka nui o ke anawaena DN50~300mm valve.
(3) nui anawaena valve nominal size DN350~1200mm valve.
(4) Nui anawaena valve nominal size DN≥1400mm valve.
3.2 Hoʻokaʻawale ʻia nā kiwi wai e ke kaomi nominal - nā kiwi me ke kaomi hana haʻahaʻa ma mua o ke kaomi lewa maʻamau.
[2] ʻO ke kaomi haʻahaʻa haʻahaʻa — kaomi nominal PN≤1.6MPa valve:
(3) Medium pressure valve — nominal pressure PN2,.5~ 6.4 mpa valve:
(4) kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe - kaomi inoa PN10. 0~80. 0MPa pahu.
(5) kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe puʻupuʻu - nominal kaomi PN≥100MPa valve.
3.3 Hoʻokaʻawale ʻia e ka mahana hana waena
(]) Puka wela wela t450 ℃.
(2) kiwi wela waena 120≤t≤450℃ valve.
{3) Pahu wela maʻamau - 29 ℃ ≤t≤120 ℃ valve.
(4) Haʻahaʻa wela wela 100 ℃ ≤t≤ 29 ℃ valve.
(5) ** kiwi wela t 100 ℃ valve.
3. 4 Hoʻokaʻawale ʻia e nā mea kino
(1) ʻAʻole metalalika kiwi e like me ka seramika kiwikā, aniani kila kiwikā, plastic kiwikā
(2) Metala kiwikā - e like me ka copper alloy valve, lead alloy valve, titanium alloy valve, chin alloy valve, Monel valve, Hastelloy valve, cast iron valve, cast steel valve, low alloy steel valve, high alloy steel valve.
(3) ʻO nā kiwipa i hoʻopaʻa ʻia i ke kino metala - e like me nā kiwi hoʻopaʻa alakaʻi, nā kiwi hoʻopaʻa ʻia i ka plastik, nā kiwi hoʻopaʻa enamel.
Nā kikoʻī o ka valve! Eia nā mea a pau āu i ʻike ʻole ai e pili ana i nā pahu Angle
Inā e lele ka Angle valve, a ʻike ʻia ua haki ke kumu o ka Angle valve, hiki iā ia ke hoʻololi wale i ka Angle valve. Inā ʻike ʻia aia ka leakage point o ka Angle valve ma ke kikowaena, e uhi hou i ke kāʻei maka a hoʻopaʻa. Ma ke ola maoli, ua pohā ka pahu huinakolu ma ka mea hoʻomehana wai i ka pau ʻana o ka hale hou o kekahi mau mea nona, ka mea i hoʻoheheʻe ʻia nā paipu a hoʻoheheʻe i ka papahele, TV cabinet, nā lole lole, etc. ʻaʻole i hoʻokumu ʻia ka valve Angle e. No laila, i ke kaʻina hana o ka hoʻonani hale, pono mākou e hoʻolohe i ke koho ʻana o ka valve Angle maikaʻi maikaʻi ʻaʻole e penny naʻauao a paona naʻaupō.
