ʻO ke kila kabone National Standard Flange Gate Valve

ʻO mākou kahi mea hana valve ʻoihana e paʻa ana i nā palapala hōʻoia ISO, API a me CE. Loaʻa iā mākou nā lako hana kiʻekiʻe a me kahi hoʻonohonoho piha o nā ʻōnaehana mana maikaʻi. ʻAe pū mākou i nā kauoha OEM a me ODM, me ka nui o nā kauoha liʻiliʻi maʻalahi. Hoʻopuka ʻia kā mākou huahana hilinaʻi ma ka honua a lanakila i ka ʻike ākea mai nā mea kūʻai aku.

He aha nā flanges kila kalapona maʻamau no nā kiwi puka?

Aia nā flanges kila kalapona ma lalo o nā kūlana like ʻole ma muli o kahi āu e hoʻohana ai iā lākou. ʻO nā mea maʻamau ka ASME B16.5 (American standard), EN 1092-1 (European standard), a me GB/T 9113 series (Chinese national standard). No kā mākou mau ʻīpuka flange maʻamau o ke kalapona kila, hahai mākou i nā kūlana GB e hoʻohālikelike i nā ʻōnaehana pipeline home. Hōʻike kēia mau maʻamau i ka nui o ka flange, ka helu kaomi, a me ke ʻano o ka puka bolt, no laila hiki i ka valve ke kūpono pono me kāu mau paipu a hoʻokō i ka papa koi koi.

He aha nā kūlana e pili ana i nā ʻīpuka puka?

ʻAʻole i hana like nā ʻīpuka puka—e hahai ana lākou i nā kūlana like ʻole e pili ana i kahi a pehea ʻoe e hoʻolālā ai e hoʻohana. No nā hana koʻikoʻi e like me ka ʻaila a me ka hoʻomaʻemaʻe kinoea, ʻo API 600 ka mea maʻamau no nā ʻīpuka kila kaumaha. ʻO ISO 6002 kekahi maʻamau honua ʻē aʻe e laina me ka API 600 no nā ʻano bonnet bolted. A no ko mākou hale a me nā papahana ʻoihana nui, hoʻohana mākou i ka maʻamau GB/T 12234 Kina. Hōʻike pololei kēlā me kēia o kēia mau maʻamau i ke ʻano o ka hoʻolālā ʻana o ka valve, nā mea e hoʻohana ai, pehea e hoʻāʻo ʻia ai no ke kaomi, a me nā ana e loaʻa iā ʻoe. Ma ia ala, ʻike ʻoe e kūpono ka valve i kāu laina a paʻa pono i ka manawa.

He aha ka hana a ka flange i loko o ka puka pā?

ʻO ka flange ke kumu "ke alo pili" ma kēlā me kēia hopena o ka valve puka. ʻO ia ka mea e hiki ai iā ʻoe ke hoʻopaʻa pono i ka valve ma kāu pipeline a i ʻole nā ​​​​mea hana ʻē aʻe. Ke hoʻopaʻa ʻoe i nā bolts, paʻi like ka flange i ka gasket e hana i kahi sila paʻa ʻole leak-leak. ʻO ia ke ʻano, ʻaʻohe leki ʻino, a ma hope inā pono ʻoe e lawe i ka valve no ka mālama ʻana a i ʻole ke pani ʻana, maʻalahi loa ke wehe a wehe. Hoʻolaha pū ka flange i ke kaomi hana ma waena o ka hui, no laila e paʻa mau ka pilina ʻoiai ke kau ʻia ka ʻōnaehana.

Hiki iā ʻoe ke wehewehe i ka maʻamau API 600?

ʻO ka API 600 kahi maʻamau paʻakikī, ʻaʻohe-nonsense mai ka American Petroleum Institute. Hana ʻia ia no nā puʻupuʻu puka kila i hoʻopaʻa ʻia - ke ʻano āu e ʻike ai ma nā hale hoʻomaʻemaʻe, nā ʻaila a me nā paipu ʻea, a me nā wahi ʻoihana koi ʻē aʻe.

ʻAʻole ia e ʻokiʻoki i nā koi: pono nā koho waiwai, pono e paʻa ka hoʻolālā, pono ka hana ʻana e hahai i nā lula koʻikoʻi, a ʻo kēlā me kēia valve e hele i nā hoʻāʻo a me nā leak ma mua o ka haʻalele ʻana i ka hale hana. He maʻalahi ka manaʻo holoʻokoʻa: e hōʻoia e hiki i ka valve ke lawe i ke kaomi kiʻekiʻe, ka wela kiʻekiʻe, a me ka media paʻakikī, a e hana mau i ka wā e pono ai ʻoe. Inā hui ka ʻīpuka i ka API 600, ʻike ʻoe ua kūkulu ʻia ia no nā noi koʻikoʻi a paʻakikī.
