Flangfly butterfly valvefly – ʻO Vilve Vilve e ka alakaʻiʻana i ka hoʻokumuʻana

1. Hōʻikeʻike

He kiwi lele lele (FBV) ʻo ia ka pahu pahu hoʻololi hapahā i ʻike nui ʻia e like me ka workhorse o ke kiʻekiʻe a me ka wai mau ʻōnaehana hoʻomalu.

Hōʻike ʻia e ko lākou mau flanges hoʻohui e kī pololei i nā flanges pipeline, hāʻawi lākou i kahi rigid, leak-proof, a me ka pilina paʻa,

ʻoi aku ka maikaʻi ma mua o nā ʻano wafer-style valve (mālama wahi akā kūpono no nā hana haʻahaʻa haʻahaʻa) a me na kiwi kaila lug (kaomi haʻahaʻa, pinepine no ka lawelawe koʻikoʻi ʻole).

• Nā Sila Mea Hoʻokele: ʻO nā apo a i ʻole PTFE bushings pale leaka wai ma ke kumu ʻoiai e ʻae ana i ka hoʻololi ʻana i ka torque maʻalahi.

5. Hana ai.uk & ʻO nā ʻano hana hana o nā ʻūpepa Flanged Butterfly

ʻO ka hanaʻana o nā kīwī lele lele (Nā FBV) koi kiʻekiʻe precision, mea paa, a me ka pili pono i nā kūlana honua e like me API 609, Iso 5752, a mensi b16.5.

Hoʻolālā ʻia nā pāpaʻi no nā noi kiʻekiʻe a me nā hana kiʻekiʻe-e like me ka aila & Nā Pīpeku hau, nā lāʻau kanu lāʻau, a me ka hana mana—pono e hōʻike dimensional pololei, incrutural integrity, a me ka leak-paa hana.

Hoʻolei ʻana i nā ʻāpana ʻĀpana Pepa

ʻO ka hoʻolei ʻana ke ala mua no ka hana ʻana i nā kino valve a me nā disc, e ʻae ana i nā geometries paʻakikī a me ka hana kumu kūʻai. No nā awāwa nui (maʻamau ma luna 12 iniha), Sand cread hoʻohana nui ʻia.

Ma kēia kaʻina hana, metala hoohehee (1450–1550°C) ua ninini ʻia i loko o nā lepo lepo i hoʻopaʻa ʻia i ka resin.

Hāʻawi ka hoʻolei ʻana i ke one i ka hoʻomanawanui ma kahi o ± 0.5 mm, kūpono ia no ke kila kalapona a i ʻole nā ​​pahu hao ductile i hoʻohana ʻia i ka wai kūloko a i ʻole nā ​​paipu ʻoihana haʻahaʻa haʻahaʻa..

No nā kiwi liʻiliʻi a liʻiliʻi (2–12 iniha) e koi ana i ka pololei kiʻekiʻe a me ka pale ʻana i ka corrosion, Kāhaka kūʻai kūʻai (ala wax nalowale) hoohanaia. Ua uhi ʻia nā ʻano wax me nā pūpū seramika, hehee aku, a pani ia me ka metala hehee.

Loaʻa kēia ʻano i nā hoʻomanawanui paʻa (± 0.1 mm) a me nā papa holo maikaʻi, hiki i nā hiʻohiʻona kikoʻī e like me nā hubs disc eccentric pālua.
He mea kūpono ka hoʻolei kālā no 316L kila kila, Hailani, a i ʻole nā ​​mea hoʻoheheʻe pale ʻino ʻē aʻe.

Kākau: Nā ʻāpana ikaika kiʻekiʻe

ʻO ka forging ke ala makemake no koʻikoʻi, nā ʻāpana kiʻekiʻe e like me nā kino, flanges, a me na kumu, no ka mea, hoʻopuka ʻo ia i ke ʻano o ka palaoa a me ka ikaika tensile kiʻekiʻe.

Metala wela (1100-1200 ° C) hana ʻia ma lalo o nā kaomi hydraulic a make paha, ka hopena i 20-30% ʻoi aku ka ikaika ma mua o nā hoʻolei like.

Hoʻohana maʻamau ʻia nā ʻāpana forged i ka papa ANSI 600 a i ʻole nā ​​kiwi kiʻekiʻe no ka ʻaila & Nā Pīpeku hau, Nā mea kanu mua, a me nā noi ʻoihana koi ʻē aʻe.

Hoʻokomo ʻia nā ʻano hana forging no ka wehe ʻana i nā ʻāpana maʻamau, pani pani ʻia no nā ʻāpana liʻiliʻi me nā ana kikoʻī, a me ka hana ʻino ʻana e hoʻoikaika i nā hui koʻikoʻi e like me nā hub disc.

Machimen: Hoʻopau pololei

Ma hope o ka hoʻolei ʻana a i ʻole ke kala ʻana, Cnc iching hōʻoia i ka pololei kiʻekiʻe, paulapua, a me ka hooponopono pono ana:

• Nā helehelena flange wili ʻia e loaʻa ka palahalaha o loko 0.1 mm a me ka hoʻokaʻawale ʻana i ka puka bolt ma nā kūlana ANSI B16.5, hōʻoia i nā pilina leak-free.
• Luna noho hoʻonani ʻia a mīkini ʻia i Ra 1.6–3.2 μm e ʻae i ka hoʻopaʻa ʻana i ka noho kūpono a me ka hoʻopaʻa ʻana maikaʻi..
• Nā diski a me nā hub, ʻoi aku ka nui o nā hoʻolālā eccentric, ua hoʻopau ʻia me 5-axis CNC milling e mālama i ka palahalaha i loko 0.05 mm no ka pani paʻa.
• ʻO nā kumu a me nā bearings huli ʻia a wili ʻia me ka pololei e hōʻoiaʻiʻo i ka hoʻololi maʻemaʻe a me ka hoʻololi ʻana o ka torque pololei.

ʻO ka mālama wela: Mechanical and Corrosion Properties

Hoʻomaikaʻi ka hana wela i ka ikaika, hālulu, a me ka pale ʻana i ka corrosion ma muli o ka mea i hoʻohana ʻia:

• 316L fesalless kila: Hoʻopili ʻia ka hopena ma 1050–1100 ° C a ukali ʻia e ka hoʻopau ʻana i ka wai e hoʻihoʻi i ke kūpaʻa corrosion a homogenize microstructure..
• Duplex 2205: Hoʻopili ʻia ka hopena ma 1020–1080°C no ka loaʻa ʻana o kahi ratio austenite/ferrite kaulike. (50:50), hoʻonui i ka ikaika a me ka pale ʻana i ka corrosion.

Mālamaʻona: Lōʻihi & Ke kū'ē neiʻo Corrosionion

ʻO ka hoʻopau ʻana i ka ʻili e hōʻoia i ka paʻa i nā kaiapuni paʻakikī:

• Hoʻolauna no ka 316L kuhiliʻole kila hoʻonui i ka natural chromium oxide papa, hoʻomaikaʻi i ka corrosion kū'ē a hiki i 20%.
• Kālai Epyore o 100-150 μm pale kino kalapona kila i ka aila & nā paipu kinoea mai ka lepo a me ka ʻino o ka lewa.
• Uilaiauliwi hoʻohana ʻia i nā hana maʻemaʻe (meaʻai, hana hānai, nā hale hakakala) e loaʻa iā Ra ≤0.8 μm, hoʻopau i nā māwae microscopic a me nā wahi make bacteria.

Kāhea & Hōʻoia maikaʻi

Ma hope o ka mīkini a me ka mālama ʻana i ka ʻili, ʻO nā valves e hui pū ʻia a me ka mana o ka maikaʻi:

• Hoʻohui noho a me ka disc: Hoʻopaʻa a paʻi ʻia nā noho, a ua hoʻonohonoho pono ʻia nā disc eccentric no ka pani pololei.
• Hoʻokomo pū: Kāhele, Paliole, a hoʻokomo ʻia nā apo-O, a ua hōʻoia ʻia ka torque.
• ʻO ka hoʻāʻo hydrostatic a i ʻole pneumatic: Hōʻoia i ka leak-paʻa i ka hana ma lalo o ke kaomi hoʻolālā.
• ʻO ka hōʻike hoʻokaumahaʻole (Ndt): Nā hana e like me ka X-ray, Ultrasinatic, a i ʻole ka nānā ʻana i nā mea pena e ʻike i nā hemahema o loko.
• Hoʻoponopono ʻana i ka mea hoʻokele: Hoʻohui, uila uila, Pnematic, a i ʻole hydraulic actuators e hoʻāʻo ʻia no ka torque a me ka pololei o ka hahau.

6. Nā helu kaomi, Kani kāne & Kūlā

Hiki ke lawelawe i ka lawelawe kinoea pi'i ki'eki'e?

ʻAe—pālua/ʻekolu eccentric flanged valve me nā noho metala (Kii 609 Palapala VI Lekage) a me nā helu ANSI Class 300–900 kūpono no ke kinoea kiʻekiʻe (E.g., kūlohelohe kūlohelohe, nitrogen).

E hōʻoia i ka hoʻokōʻana me ka iso 15848-1 Papah ah no nā mea haʻahaʻa haʻahaʻa haʻahaʻa.

He aha ka nui kiʻekiʻe o ka valve lele lele?

Hāʻawi ka hapa nui o nā mea hana i nā valve lele lele a hiki i 48 iniha (1200 mm) I ka heluna, kūpono no nā mea kanu wai nui a me ka ʻaila & Nā Pīpeku hau.

Hiki i nā hoʻolālā maʻamau ke hiki 60 iniha (1500 mm) no nā noi kūikawā.

Pehea wau e pale ai i ka leaka o ka flange gasket?

E hoʻohana i nā gaskets kūpono me ka wai/mahana (E.g., graphite no ka mahu, PTFE no nā kemika); e hoʻopaʻa i nā kī ma ke ʻano crisscross (no ASME PCC-1) i ka like ole torque (E.g., 70 N·m no 6-ʻīniha ANSI 300 flanges); hoʻololi i nā gaskets i kēlā me kēia makahiki.

He mau kiwi lele flanged kūpono no ka lawelawe maʻemaʻe?

ʻAe—koho i nā kino 316L me nā ʻili uila (RE ≤0.8 μM), Nā'Āpana PTF, a me nā ʻāpana liʻiliʻi ʻekolu (3-A/EHEDG pili).

Hoʻohana ʻia kēia mau kiwi i ka waiū, hana hānai, a me ka hana lāʻau lapaʻau.

He aha kaʻokoʻa ma waena o ka papa ansi 300 a 600 nā kīpē flanged?

Ansi papa 300 nā mea kūʻai aku i ka 70 Bar (20° C), oiai o ka papa 600 hana lima a 140 Bar (20° C).

Papa hana 600 ʻoi aku ka mānoanoa o nā kino (20-30 mm vs. 15–20 mm no ka Papa 300) a ʻoi aku ka ikaika o nā flanges, e hoʻolilo iā lākou i kūpono no nā noi kiʻekiʻe e like me nā refineries a me nā pipeline o waho.
