ʻO Titanium B367 GC-2 Poʻo Poʻo
Aia 3 ʻano o nā ʻano hoʻohui: pili flange, pili kaula, a me ka pilina but-welded. Ma hope o ka ʻike ʻia ʻana o nā kiwi hoʻopaʻa paʻa ponoʻī, hoʻololi ka ʻaoʻao kahe o ka pahu pani pani mai luna aʻe o ka disc valve e komo i ke keʻena valve. I kēia manawa, ma lalo o ke kaomi o ka waena, he liʻiliʻi ka ikaika e pani i ka valve, ʻoiai ka ikaika e wehe i ka valve he nui, a hiki ke hoʻemi ʻia ke anawaena o ke kumu valve. I ka manawa like, ma lalo o ka hana a ka medium, ua paʻa pū kēia ʻano valve. ʻO ka "Three Modernizations" o nā valves i ko mākou ʻāina i ʻōlelo mua ʻia e pono ke kahe ʻana o nā kiwi honua mai luna a lalo. Ke wehe ʻia ka pahu pani pani, ʻo ke kiʻekiʻe wehe o ka disc valve he 25% a 30% o ke anawaena inoa. Ke hiki i ka nui o ke kahe i kona kiʻekiʻe, e hōʻike ana ua hōʻea ka valve i ke kūlana hāmama piha. No laila, pono e hoʻoholo ʻia ke kūlana hāmama piha o ka valve pani ʻia e ka hahau ʻana o ka disc valve.
ʻO ka ʻāpana wehe a pani ʻana o kahi pahu pani, ʻo Globe Valve, he ʻano pahu pahu pahu, me ka ʻili palahalaha a conical paha ma ka ʻili hoʻopaʻa. Ke neʻe nei ka disc valve ma kahi laina pololei ma ka laina waena o ka noho valve. Hiki ke hoʻohana ʻia ke ʻano o ka neʻe ʻana o ke kumu valve, i kapa ʻia ʻo ke koʻokoʻo huna, e hoʻomalu i ke kahe ʻana o nā ʻano wai like ʻole e like me ka ea, ka wai, ka mahu, nā ʻano media corrosive, ka lepo, ka aila, ka metala wai, a me ka media radioactive. ma o ke ʻano lāʻau hāpai a me ka ʻaupuni. No laila, kūpono loa kēia ʻano valve pani no ka ʻoki, hoʻoponopono, a me ka throttling kumu. Ma muli o ka wehe pōkole ʻana a i ʻole ka pani pani ʻana o ka pahu valve a me ka hana ʻoki ʻoki hilinaʻi loa, a me ka pilina kūlike ma waena o ka hoʻololi ʻana o ka wehe ʻana o ka noho valve a me ka hahau ʻana o ka disc valve, ʻo kēia ʻano valve he nui loa. kūpono no ka hoʻoponopono ʻana i ke kahe.

Nā mea hou aku
ʻO ke kumu hana o nā pahu kila kila, ʻo ia ka hoʻohuli ʻana i ka valve i mea e pale ʻole ai ka pahu. He māmā nā ʻīpuka puka, liʻiliʻi ka nui, a hiki ke hana i nā anawaena nui. Loaʻa iā lākou ka hoʻopaʻa paʻa ʻana, ka hana maʻalahi, a me ka mālama pono. Paʻa pinepine ka ʻili hoʻopaʻa a me ka ʻili spherical a ʻaʻole hiki ke hoʻopau ʻia e ka media. Hoʻohana nui ʻia lākou i nā ʻoihana like ʻole.
ʻO ka hui hoʻopaʻa ʻana o ka pahu pani pani ʻia ʻo ka ʻili hoʻopaʻa o ka disc valve a me ka ʻili hoʻopaʻa o ka noho valve. Hoʻokuʻu ke kumu valve i ka disc valve e neʻe pololei ma ka laina waena o ka noho valve. I ka wā o ka weheʻana a me ka hoʻopauʻana o ka valve pani, heʻuʻuku ke kiʻekiʻe o ka weheʻana, e maʻalahi ka hoʻololiʻana i ke kahe o ke kahe, a maʻalahi ka hanaʻana a me ka mālamaʻana, me ka nui o nā noi kaomi.
ʻAʻole maʻalahi a ʻāwili ʻia ka ʻili hoʻopaʻa ʻana o ka valve honua, a ʻaʻohe mea hoʻoheheʻe pili ma waena o ka disc valve a me ka ili hoʻopaʻa noho valve i ka wā o ka wehe ʻana a me ke kaʻina pani. No laila, liʻiliʻi ka ʻaʻahu a me ka ʻōpala ma ka ʻili o ka sila, kahi e hoʻomaikaʻi ai i ke ola lawelawe o ka hui sila. Loaʻa i ka valve puni honua kahi kīwī kīwī liʻiliʻi a me kahi kiʻekiʻe liʻiliʻi i ka wā o ke kaʻina hana pani piha. ʻO ka hemahema o ka valve pani ʻia ʻo ia ka nui o ka wehe a me ka pani pani ʻana a paʻakikī ke hoʻokō i ka wehe wikiwiki a me ka pani ʻana. Ma muli o ke kahe ʻana o ka wai i loko o ke kino valve, ʻoi aku ka kiʻekiʻe o ke kahe ʻana o ka wai, e hopena i ka nalowale nui o ka mana wai ma ka pipeline.
Nā hiʻohiʻona hale:
1. Wehe a pani ʻole me ka hakakā ʻole. Hoʻopau loa kēia hana i ka pilikia o nā valve kuʻuna e pili ana i ka hoʻopaʻa ʻana ma muli o ke kuʻekuʻe ʻana ma waena o nā wahi hoʻopaʻa.
2. ʻO ka hale i kau ʻia ma luna. Hiki ke nānā pono ʻia a hoʻoponopono ʻia nā valves i kau ʻia ma nā pipeline, hiki ke hōʻemi pono i ka manawa haʻahaʻa o ka hāmeʻa a hoʻohaʻahaʻa i nā kumukūʻai.
3. Hoʻolālā noho hoʻokahi. Hoʻopau i ka pilikia o ka piʻi ʻana o ke kaomi maʻamau i loko o ke keʻena o ka valve, e pili ana i ka palekana o ka hoʻohana.
4. Hoʻolālā torque haʻahaʻa. Hiki ke wehe maʻalahi a pani ʻia ka pahu valve me kahi hoʻolālā hoʻolālā kūikawā me kahi pahu liʻiliʻi liʻiliʻi.
5. Ke ano o ka wedge sealing structure. Ke hilinaʻi nei ʻo Valves i ka ikaika mechanical i hāʻawi ʻia e ka pahu valve e kaomi i ka wili pōleʻa ma luna o ka noho valve a me ka sila, e hōʻoia ana ʻaʻole i hoʻopilikia ʻia ka hana hoʻopaʻa ʻana o ka valve e nā loli i ka ʻokoʻa o ka paipu paipu, a ua hōʻoia ʻia ka hana sealing hilinaʻi ma lalo o nā hana like ʻole. kūlana.
6. Ka hoʻomaʻemaʻe ponoʻī ʻana o ka ili hoʻopaʻa. Ke hoʻokuʻu ʻia ka pōʻai mai ka noho valve, e hele like ka wai i loko o ka pipeline ma ka ʻaoʻao hoʻopaʻa o ka sphere ma kahi kihi 360 °, ʻaʻole wale ka hoʻopau ʻana i ka ʻōpala kūloko o ka noho valve e ka wai kiʻekiʻe. ka hōʻiliʻili ʻana ma ka ʻili o ka sila, e hoʻokō i ke kumu o ka hoʻomaʻemaʻe ponoʻī.
7. ʻO nā kino valve a me nā uhi me ke anawaena ma lalo o DN50 he mau ʻāpana hana ia, aʻo nā mea me ke anawaena ma luna o DN65 he mau ʻāpana kila.
8. 'Oko'a ka pilina ma waena o ke kino kiwi a me ka uhi valve, e like me ka ho'oku'i 'ana i ka lā'au pa'i pa'i, ka ho'oku'i flange gasket, a me ka ho'opili kaula ho'opa'a pono'ī.
9. Hana ʻia nā ʻili hoʻopaʻa o ka noho valve a me ka disc i ka wiliwili plasma a i ʻole ka uhi ʻana o ka cobalt chromium tungsten paʻa paʻa. He kiʻekiʻe ka paʻakikī o nā mea hoʻopaʻa paʻa, hoʻopaʻa i ke kūpaʻa, kūʻē i ka abrasion, a me ke ola lawelawe lōʻihi.
10. He kila nitrided ke kumu o ka pahu valve, a he ki'eki'e ka pa'akikī ili o ke kumu o ka valve nitrided, hiki ke ho'opa'a 'ia, ke ku'eku'e, a me ka corrosion-resistant, me ka lō'ihi o ka lawelawe 'ana.
