Valves za Cryogenic ni iki: Ubwoko, Imikoreshereze (LNG, Ubuvuzi)

1. Intangiriro ku mavalue ya Cryogenic

Valive zikoresha amashanyarazini valves zakozwe mu buryo bwihariye zikoreshwa mu kugenzura urujya n'uruza rw'amazi n'imyuka bikonje cyane, akenshi ku bushyuhe buri munsi-40°C (-40°F)Izi valve ni ingenzi mu micungire y'ingandagaze karemano itemba (LNG), azote y'amazi, ogisijeni, hidrojeni, na heliyumu, aho valve zisanzwe zangirika bitewe n'ubushyuhe, kwangirika kw'ibikoresho, cyangwa kwangirika kw'ibifunga.

Kugira ngo ikore neza kandi mu buryo butekanye, valves zikozwe mu buryo bw’ikoranabuhanga zikozwe mu bikoresho bidasanzwe, amashami maremare, n’uburyo bwihariye bwo kuziba kugira ngo zihangane n’ubushyuhe buri hasi cyane nta gusohoka cyangwa kwangirika kw’imashini.

2. Ibiranga by'ingenzi by'imiterere ya Cryogenic Valves

Bitandukanye na vali zisanzwe, vali zikoresha uburyo bwa cryogenic zirimo ibintu byihariye byo guhangana n'ubukonje bukabije:

2.1 Bonnet Yagutse (Iyongerewe ry'Ingingo)

- Birinda ko ubushyuhe buva mu bidukikije bujya mu gice cy'umubiri w'ingufu, bigabanya ikorwa ry'urubura.

- Igumana igipakira n'icyuma gitera imbaraga ku bushyuhe bw'ikirere kugira ngo ikore neza.

2.2 Ibikoresho byihariye byo gufunga

- ImikoresherezePTFE (Teflon), graphite, cyangwa seal z'icyumagukomeza gufunga neza nubwo haba hari ubushyuhe bwinshi.

- Irinda gusohoka kw'amazi, ibyo bikaba ari ingenzi cyane ku myuka ihumanya nka LNG cyangwa ogisijeni y'amazi.

2.3 Ibikoresho by'umubiri bikomeye

- Byakozwe muriicyuma kitagira umwanda (SS316, SS304L), umuringa, cyangwa aloyi za nikelikurwanya ububobere.

- Hari uburyo bwo gukoresha valve zikoresha umuvuduko mwinshiicyuma cy'ubucuzikugira ngo habeho imbaraga nyinshi.

2.4 Gukingira Umwotsi mu Gifu (Birakenewe mu gihe cy'ubukonje bukabije)

- Hari imiterere ya valvesamakoti yo mu bwoko bwa vacuum afite inkuta ebyirikugira ngo ugabanye ukwinjira k'ubushyuhe mu gihe ubushyuhe buri hasi cyane.

3. Gushyira mu byiciro Valves za Cryogenic

3.1 Ukurikije Ingano y'Ubushyuhe

3.2 Ukurikije ubwoko bwa Valve

- Valves z'umupira zikoresha ibyuma bishyushya– Ni byiza kuzimya vuba; bikunze gukoreshwa muri sisitemu za LNG na gaze zo mu nganda.

- Valves z'irembo zikoresha uburyo bwa Cryogenic– Ikoreshwa mu kugenzura neza no gufunga neza, nta kugabanuka cyane k'umuvuduko.

- Valves z'isi zikoresha ikoranabuhanga rya Cryogenic Globe- Gutanga amabwiriza nyayo agenga imiyoboro y'amazi anyuramo.

- Valves zo kugenzura Cryogenic– Kurinda gusubira inyuma kw'amazi mu buryo bushyuha buhoro.

- Valves z'ibinyugunyugu zikoresha Cryogenic– Yoroshye kandi ntoya, ikwiriye imiyoboro minini. 

3.3 Binyuze mu gusaba

- Valves za LNG– Gufata gaze karemano yashongeshejwe ku-162°C (-260°F).

- Ibyerekeye Ikiresiteri n'Ubwunganizi mu by'Indege– Ikoreshwa mu buryo bwa roketi zikoresha lisansi (hydrogen na ogisijeni).

- Ubuvuzi n'Ubumenyi– Iboneka mu mashini za MRI no mu bubiko bw'amashusho akoresha uburyo bwa cryogenic.

- Gutunganya Gazi mu Nganda– Ikoreshwa mu nganda zitandukanya umwuka (ogisijeni, azote, argon).

4. Ibyiza bya Cryogenic Valves

✔Imikorere idashingiye ku gusohoka kw'amazi- Gufunga neza birinda amazi aturuka mu mwuka mubi.

✔Uburyo bwo gukoresha neza ubushyuhe– Amabonneti maremare n'ubushyuhe bigabanya ubushyuhe.

✔Kuramba– Ibikoresho byo mu rwego rwo hejuru birwanya gucika no kwangirika.

✔Iyubahirizwa ry'Umutekano– AmahuriroASME, BS, ISO, na APIamahame ngenderwaho yo gukoresha imiti igabanya ubukana bw'ibicurane.

✔Gusana bike– Yagenewe kwizerwa igihe kirekire mu bihe bikomeye.

5. Itandukaniro ry'ingenzi hagati ya Cryogenic na Ordinary Valves

Umwanzuro

Valive zikoresha amashanyarazini ingenzi ku nganda zikora ku binyabutabire bishyuha cyane. Imiterere yazo yihariye—irimoingofero ndende, ibifunga bikonjesha cyane, n'ibikoresho biramba—bituma bikora neza kandi mu buryo bwizewe mu bihe bikomeye. Gusobanukirwa ibyiciro byabyo, ibyiza, n'itandukaniro ryabyo ugereranije n'ibipimo bisanzwe bifasha mu guhitamo ibipimo bikwiye byo gukoresha mu buryo busaba imbaraga nyinshi.
