Nā mea hana ʻo Cryogenic Valves

Nā kikoʻī huahana a me nā ʻāpana hoʻolālā:

1. Paʻi helu: 150, 300, 600Lb, 900lb, 1500Lb (45MPa).

2. Ke anawaena o ke kiwi: 15 ~ 1200 mm (1 / 2 ~ 48 ").

3. Ke ano pili: flange type, welding type and thread.

4. ʻO nā mea pahū: LCB, LC3 a me CF8.

5. Ka wela hana: – 46 ℃, – 101 ℃, – 196 ℃, – 253 ℃.

6. Media pili: liquefied maoli kinoea, ethylene, propylene, etc.

7. Keʻano hoʻokele: manual, bevel gear transmission a me ka uila.

Haʻahaʻa wela valve kūlana a me ka huahana:

1. Hoʻolālā: API6D, JB / t7749

2. Ka nānā maʻamau a me ka hoʻāʻo ʻana i nā kiwi: e like me ka maʻamau API598.

3. Nānā haʻahaʻa wela a me ka hoʻāʻo ʻana o nā kiwi: e like me JB / t7749.

4. Keʻano hoʻokele: manual, bevel gear drive a me ka uila uila.

5. Ke ano o ka noho kiwi: ua apono ka noho kiwi i ke ano welded, a ua uhiia ka ili hoailona me ka cobalt based hard alloy e hooiaio i ka hana sealing of the valve.

6. ʻO ka hipa kāne he ʻano elastic, a ua hoʻolālā ʻia ka lua hoʻomaha kaomi ma ka hopena inlet.

7. Ua kaha 'ia ke kino valve o ke ala ho'okahi ala me ka kaha kuhikuhi kahe.

8. Haʻahaʻa wela kinipōpō pōlele, puka pā, puni honua a me butterfly valve hoʻohana i ka ʻāʻī lōʻihi e pale i ka paʻi.

9. Ultra haʻahaʻa wela kini poepoe maʻamau: JB / t8861-2004.

Koho haʻahaʻa wela wela mea:

1. ʻO ke kino valve a me ka pāpale he LCB (- 46 ℃), LC3 (- 101 ℃), CF8 (304) (- 196 ℃).

2. Ram: ke kila kuhiliʻole i hoʻopaʻa ʻia i luna o ka cobalt ma muli o ke kinikini paʻa.

3. Noho kiwi: ke kila kuhiliʻole i luna o ka cobalt ma muli o ka paʻa paʻa.

4. Puka pahu: 0Cr18Ni9.

ʻO ka hana ʻana a me ka hoʻāʻo ʻana o ka valve wela haʻahaʻa:

Hoʻokumu ʻia ke kaʻina hana koʻikoʻi a me nā mea hana kūikawā no nā valve haʻahaʻa haʻahaʻa i hana ʻia, a mālama ʻia ka mana koʻikoʻi no ka hana ʻana i nā ʻāpana. Ma hope o ka hoʻomaʻamaʻa haʻahaʻa haʻahaʻa haʻahaʻa, waiho ʻia nā ʻāpana mīkini i loko o ka mea hoʻomaha no kekahi mau hola (2-6 mau hola) e hoʻokuʻu i ke kaumaha, e hōʻoia i ka hana haʻahaʻa haʻahaʻa o ka mea, e hōʻoia i ka nui hoʻopau, a pale i ka leakage. i hana ʻia e ka deformation o ka valve ma muli o ka hoʻololi ʻana o ka mahana ma lalo o ke kūlana hana haʻahaʻa haʻahaʻa. Heʻokoʻa ka hui o ka valve mai ka valve maʻamau. Pono e hoʻomaʻemaʻe pono ʻia nā ʻāpana e wehe i kahi ʻaila hinu e hōʻoia i ka hana lawelawe.

Mea ho'āʻo valve wela haʻahaʻa:

1. Haʻahaʻa wela wela hoao mea

2. Mea hoʻopaʻa wai nitrogen

3. Haʻahaʻa wela lapaʻau pahu

4. Haʻahaʻa haʻahaʻa wela ho'āʻo pae e hōʻoia i ka hana o ka valve ma lalo o haʻahaʻa wela kūlana

5. ʻO kekahi

ʻO ka hoʻāʻo a me ka nānā ʻana i ka valve wela haʻahaʻa:

ʻO nā ʻāpana nui o nā kiwi haʻahaʻa haʻahaʻa e hoʻokō ʻia i ka mālama haʻahaʻa haʻahaʻa a e mālama ʻia ka hoʻāʻo ʻana i ka hopena haʻahaʻa haʻahaʻa no kēlā me kēia pūʻulu o nā laʻana e hōʻoia ai ʻaʻole palupalu nā kiwi ma lalo o nā kūlana haʻahaʻa haʻahaʻa a hiki ke kū i ke ʻano haʻahaʻa haʻahaʻa. hopena.

E hana i kēia mau hoʻokolohua ma kēlā me kēia valve:

1. ʻO ka ho'āʻo ikaika o ka pūpū wela maʻamau;

2. Ho'āʻo sila i ka mahana maʻamau a me ke kaomi haʻahaʻa;

3. ʻO ka mahana maʻamau a me ka haʻahaʻa haʻahaʻa sealing ho'āʻo;

4. Haʻahaʻa wela luna sila ea tightness hoao (me ka sila luna);

5. Haʻahaʻa wela kinoea seal ho'āʻo, etc. e hōʻoia i ka holoʻokoʻa haʻahaʻa wela valve e hoʻokō i nā koi o ka maʻamau;

6. E hana i ka lapaʻau haʻahaʻa haʻahaʻa no nā ʻāpana nui a me nā ʻāpana a hana i ka hoʻāʻo ʻana i ka hopena haʻahaʻa haʻahaʻa no kēlā me kēia pūʻulu o nā laʻana e hōʻoia ʻaʻole palupalu nā kiwi ma lalo o nā kūlana haʻahaʻa haʻahaʻa a hiki ke kū i ka hopena haʻahaʻa haʻahaʻa;

7. E ho'ā'o 'ia ka wela ha'aha'a (cryogenic) e like me nā kiko'ī pili;

8. ʻOi aku ka mana o ka hana electrostatic. ʻO ke kūpaʻa conduction ma waena o ke kino valve a me ke kumu valve a i ʻole ma waena o nā kūloko a me ke kino valve ʻoi aku ka liʻiliʻi ma mua o 1 ohm.
