ʻO ka maʻamau BS 1873 e pili ana i kahi kūlana Pelekane kūikawā no nā kīwaha honua me nā pāpale bolted.ʻO ka inoa ʻo "BS 1873" e hōʻike ana e kūlike ka valve i nā kūlana i hoʻonohonoho ʻia e ka British Standards Institution (BSI) no kēia ʻano valve. ka hoʻopaʻa ʻana i ke kahe o ka wai i loko o kahi paipu.ʻO ka hoʻolālā bonnet bolted e hiki ke komo maʻalahi i loko o ka valve no ka mālamaʻana a me ka hoʻoponoponoʻana.He kūpono ka pahu pahu po'omana'o i nā noi kahi e pono ai ke pani pa'a 'ia a ma kahi e pono ai ka mālama 'ana a i 'ole ka nānā 'ana o ka valve internals. hōʻoia i ko lākou hilinaʻi a me ka hana.Hiki i kēia mau pae hoʻohālikelike ke hoʻokomo i nā kikoʻī no nā mea waiwai, nā helu kaomi-mehana, nā hoʻopili hope, a me nā hiʻohiʻona pili ʻē aʻe. Ke kuhikuhi a koho ʻana i kahi BS 1873 globe valve me kahi pāpale bolted, pono e noʻonoʻo i nā mea e like me ka noi i manaʻo ʻia, nā kūlana hana, nā waiwai wai, nā koi a me nā koi wela, a me nā kūlana ʻoihana kūpono a i ʻole nā kānāwai..
1. Frictionless wehe a pani.Hoʻopau loa kēia hana i ka pilikia e pili ana i ka hoʻopaʻa ʻana o nā kiwi kuʻuna e ka friction ma waena o nā mea hoʻopaʻa.
2, hale ʻano ʻano luna.Hiki ke nānā pono ʻia a hoʻoponopono ʻia ka valve i hoʻokomo ʻia ma ka pipeline ma ka pūnaewele, hiki ke hōʻemi pono i ka kaʻa kaʻa a hoʻemi i ke kumukūʻai.
3, hoʻolālā noho hoʻokahi.Hoʻopau ʻia ka pilikia e pili ana i ka mea waena i loko o ka lua valve e ka piʻi ʻana o ke kaomi maʻamau.
4, hoʻolālā torque haʻahaʻa.Hiki ke wehe maʻalahi a pani ʻia ka puʻupuʻu valve me kahi hoʻolālā hoʻolālā kūikawā me kahi lima liʻiliʻi.
5, wili sila hoʻolālā.Hoʻopaʻa ʻia ka valve e ka ikaika mechanical i hāʻawi ʻia e ka pahu valve, a ua kaomi ʻia ka wili pōleʻa i ka noho, i ʻole e hoʻopili ʻia ka hoʻopaʻa ʻana o ka valve e ka hoʻololi ʻana o ka ʻokoʻa kaomi o ka pipeline, a ʻo ka hana sealing. hilinaʻi ʻia ma lalo o nā kūlana hana like ʻole.
6. Hoʻomaʻemaʻe ponoʻī i ka ʻili o ka sila.Ke hili ʻia ka pōleʻa mai ka noho, hele ka wai i loko o ka pipeline i 360 ° ma ka ʻaoʻao hoʻopaʻa o ka pōleʻa, ʻaʻole ia e hoʻopau wale i ka ʻānai kūloko o ka wai kiʻekiʻe ma ka noho, akā holoi pū nō hoʻi i ka hōʻiliʻili ʻana ma luna. ka ʻili o ka sila e hoʻokō i ke kumu o ka hoʻomaʻemaʻe ponoʻī.
7, valve anawaena DN50 ma lalo o ka valve kino, valve uhi e forging 'āpana, DN65 ma luna o ka valve kino, valve uhi ua hoolei kila.
8, ʻo ke kino valve a me ka uhi valve he mau ʻano pili like ʻole, pili pin clamp, pili flange gasket a me ka hoʻopaʻa ʻana iā ia iho.
9. ʻO ka ili hoʻopaʻa ʻana o ka noho valve a me ka flap valve i hana ʻia me ka plasma spray welding a i ʻole i luna o ka cobalt chromium tungsten carbide, nona ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻana, ke kūpaʻa abrasion a me ke ola lōʻihi.
10, ʻo ka mea pahu pahu he nitriding steel, nitriding valve stem surface hardness, wear resistance, abrasion resistance, corrosion resistance, long service life.
I ka wā o ka wehe ʻana a me ka pani ʻana o ka pahu kila kila, no ka mea, ʻoi aku ka liʻiliʻi o ka friction ma waena o ka disc a me ka ʻili hoʻopaʻa ʻana o ke kino valve ma mua o ko ka valve puka, ʻaʻole hiki ke ʻaʻahu.
ʻO ka wehe ʻana a i ʻole ka pani ʻana o ka pahu valve he pōkole, a he hana ʻokiʻoki hilinaʻi loa ia, a no ka mea ʻo ka hoʻololi ʻana o ke awa noho valve e like me ka hahau ʻana o ka disc valve, kūpono loa ia no ka hoʻoponopono. o ke kahe ana.No laila, kūpono loa kēia ʻano valve no ka ʻoki ʻoki a i ʻole ka hoʻoponopono a me ka throttling.

Ma ke ʻano he mea hana a me ka mea kūʻai aku, ke hoʻohiki nei mākou e hāʻawi i nā mea kūʻai aku me ka lawelawe ma hope o ke kūʻai aku kiʻekiʻe, me kēia mau mea:
1. Hāʻawi i nā alakaʻi hoʻohana huahana a me nā manaʻo mālama.
2.No nā hemahema i hana ʻia e nā pilikia maikaʻi o ka huahana, hoʻohiki mākou e hāʻawi i ke kākoʻo ʻenehana a me ka hoʻoponopono pilikia i loko o ka manawa pōkole loa.
3.Except no ka pōʻino i hanaʻia e ka hoʻohana maʻamau, hāʻawi mākou i nā lawelawe hoʻoponopono manuahi a me nā pani pani.
4. Ke hoʻohiki nei mākou e pane wikiwiki i nā pono lawelawe o ka mea kūʻai aku i ka wā o ka hōʻoia huahana.
5. Hāʻawi mākou i ke kākoʻo ʻenehana no ka wā lōʻihi, nā lawelawe kūkākūkā pūnaewele a me nā lawelawe hoʻomaʻamaʻa.ʻO kā mākou pahuhopu ka hāʻawi ʻana i nā mea kūʻai aku i ka ʻike lawelawe maikaʻi loa a hoʻolilo i ka ʻike o nā mea kūʻai aku i mea ʻoluʻolu a maʻalahi.
