LNG itumizwa mu mahanga iva mu byuma bitwara imizigo yinjira mu bigega byo kubikamo ibintu binyuze mu maboko yo gupakurura, igenzurwa na valves za cryogenic globe kugira ngo igenzurwe neza. Valves zacu zubahiriza BS 6364 na ISO 28921-1 kuri serivisi ya LNG.
Inganda zikora amazi ya LNG
Gazi karemano ikonjeshwa kugeza kuri -162°C kugira ngo ikoreshwe. Amavali y'isi akoresha amashanyarazi acukura agenzura uburyo bwo gukwirakwiza ubushyuhe, amasegura, n'inkingi zo gutandukanya ibintu hamwe n'ubushobozi bwo gufunga neza.
Ibikoresho byo Gutandukanya Umwotsi (ASU)
Azote y'amazi (-196°C), ogisijeni y'amazi (-183°C), na argon y'amazi (-186°C). Amavali y'isi akoresha cryogenic agenzura ikurwa n'ububiko bw'ibicuruzwa mu buryo bwizewe.
Serivisi ya Hydrogen y'amazi
Hydrogen y'amazi kuri -253°C ikenera valves zihariye zo mu bwoko bwa cryogenic globe zifite udupira twagutse n'intebe za PCTFE.
Ibimera bya ethylene na propylene
Ubushyuhe buri hasi bukoreshwa hagati ya -40°C na -104°C. Valve zikoresha ikirere gishyushye zikoreshwa mu bice bikonje bya ethylene na firigo za propylene.
Ibikoresho byo kubikamo ibintu bihumanya
Aho gusohokera ikigega n'aho kwinjira bishyirwa mu bigega byo kubikamo ibintu bidafite aho bihuriye bisaba kuzimya valve y'isi yose neza.
Imiyoboro y'agasanduku gakonje
Imashini itandukanya umwuka n'agasanduku gakonjesha ikoresha imiyoboro y'imbere y'agasanduku gakonjesha ikoresha valve z'isi zikoresha uburyo bwo kugenzura ibikorwa.
Sisitemu zo Gukonjesha
Sisitemu zo gukonjesha zikoreshwa mu nganda zikoresha valve zo mu bwoko bwa globe mu kugenzura amazi anyuramo.
9. Gupakira no Kohereza – Cryogenic Globe Valve (-196°C)
Gupfunyika
- Uburinzi:Valve zose zipfunyitse mu mpapuro zirinda ingese cyangwa impapuro za VCI. Impapuro zipfunyitse n'impapuro zifatanye zipfundikiwe imipfundikizo ya pulasitiki cyangwa ibyuma bifunga ibyuma.
- Uburinzi bwa nyuma:Imipfundikizo ya pulasitiki yo ku mpera za SW/NPT; imipfundikizo y'icyuma ifite gaskets zo ku mpera zifatanye. Imipfundikizo yo ku buti irinzwe n'imipfundikizo ya pulasitiki cyangwa icyuma.
- Amasanduku y'ibiti:Ku mavali mato, ibikoresho byihariye cyangwa byinshi bipakiye mu masanduku akomeye y'ibiti afite ifuro. Amasanduku ya plywood yo mu rwego rwo hejuru afite imigozi yo mu mfuruka.
- Ingobyi z'ibyuma:Ku mavali manini, ibyuma byihariye bifite inkingi zifatanye. Amavali afashwe n'imigozi ku mavali.
- Umuti wo kuvura indwara:Imifuka yo kugabanya ubushyuhe ya silica gel ishyirwa mu masanduku kugira ngo itware ubushuhe.
Kohereza
- Uburyo bwo gutwara abantu:Imitwaro yo mu kirere ku byihutirwa; imitwaro yo mu mazi ku byuma binini n'ibicuruzwa byinshi.
- Gushyira mu bikoresho bya kontenari:Vali nto zishyirwa mu mapaki kandi zigashyirwa mu byuma; vali nini zishyirwa mu byuma binini binini.
- Ibirango:Buri gasanduku kanditseho inomero ya shashi y'ingufu, ingano, urwego rw'umuvuduko, ibikoresho, inomero y'uruhererekane, n'amabwiriza yo kuyikoresha.

Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) – Cryogenic Globe Valve (-196°C)
Q: Ni irihe tandukaniro riri hagati ya valve y'isi ikoresha ikoranabuhanga rya cryogenic na valve isanzwe ikoresha ikoranabuhanga rya globe?
A: Vali zo mu bwoko bwa Cryogenic globe zifite ibintu byinshi by'ingenzi bitaboneka muri vali zisanzwe: bonnet ndende ifite drip plate yo kurinda stem seal; uburyo bwo kuvura ibice byose byimbitse bya cryogenic; ibikoresho byihariye byo kwicaraho (PCTFE, PEEK) ku bushyuhe buri hasi; gupakira imyuka mike ihumanya ikirere; hamwe n'ibizamini by'imikorere ya cryogenic nk'uko biteganywa na BS 6364.
Q: Ni ubushyuhe buke bwa serivisi kuri valves zawe z'isi zikoresha amashanyarazi (cryogenic globe valves)?
A: Valve zacu zisanzwe za cryogenic globe zihabwa amanota kuri -196°C kuri buri BS 6364. Kuri serivisi ya hydrogen y'amazi (-253°C) cyangwa heliyumu y'amazi (-269°C), dutanga imiterere yihariye.
Q: Ubuvuzi buteye ubwoba bw’indwara y’impyiko (deep cryogenic treatment) ni iki kandi kuki bukenewe?
A: Gukoresha uburyo bwa "deep cryogenic treatment" ni uburyo bwo gukonjesha ibice bya valve kugeza kuri -196°C mu gihe cy'amasaha 8. Ibi bihindura "austenite" igumanye, bigabanya imihangayiko isigaye, kandi bigatanga ubuziranenge buhamye ku bushyuhe bwa serivisi.
Q: Ni ibihe bikoresho by'intebe usaba serivisi yo gukoresha -196°C?
A: Ku bijyanye na serivisi ya -196°C, turasaba PCTFE nk'igikoresho cy'ingenzi cyo kwicaraho. PCTFE igumana imiterere yayo ya mekanike kandi igafunga neza ku bushyuhe bukabije.
Q: Ese gupima imikorere ya cryogenic ni itegeko?
A: Dukurikije BS 6364 na ISO 28921-1, isuzuma ry’imikorere ya cryogenic ni itegeko ku mavali akoreshwa muri LNG na serivisi ya cryogenic. Womic ikora isuzuma ry’imikorere ya cryogenic 100%.
Q: Ese mutanga uburyo bwo gufunga ifuro ku gihe nta gusohora amazi?
A: Yego. Ku bikorwa by'ingenzi bisaba ko inkingi zidasohoka neza (nk'amazi yangiza cyangwa ahenze), dutanga igishushanyo mbonera cy'inyuma gifite intebe y'inyuma.
Q: Ni ryari igihe gisanzwe cyo gutanga valves z’isi zikoresha amashanyarazi (cryogenic globe valves) gikoreshwa?
A: Igihe gisanzwe cyo gutanga umusanzu ni ibyumweru 8-12 ku miterere isanzwe. Ku ngano nini (> 12") cyangwa ibikoresho byihariye, igihe cyo gutanga umusanzu ni ibyumweru 12-16.
Ubunararibonye mu mushinga n'inyigo y'ikizamini - Cryogenic Globe Valve (-196°C)
Umushinga
Kwagura Ishami ryo Gutandukanya Imodoka - Zhejiang, mu Bushinwa
Isanzwe n'Impamyabumenyi
BS 6364, BS 1873, ISO 28921-1
Ibisobanuro n'ingano:
- Valves za Cryogenic Globe za 8" (DN200), Class 300, CF3M Body, PCTFE Seats – 12
- Valves za Cryogenic Globe za 6" (DN150), Icyiciro cya 300, Umubiri wa CF3M, Imyanya ya PCTFE – ibice 24
- Valves za Cryogenic Globe za 4" (DN100), Icyiciro cya 300, Umubiri wa CF3M, Imyanya ya PCTFE – ibice 36
- Valves za Cryogenic Globe za 2" (DN50), Icyiciro cya 300, Umubiri wa CF3M, Imyanya ya PCTFE – ibice 48
Igiteranyo:Ibice 120
Ikoreshwa:Azote y'amazi (-196°C) na ogisijeni y'amazi (-183°C) ikoreshwa mu gukura no kubika ibicuruzwa. Igitutu cy'imiterere: 5.0 MPa. Ipfundo rinini rifite icyuma gitonyanga, rikoreshwa n'urukiramende rw'intoki.
Ibibazo bya tekiniki n'ibisubizo:
1. Kugenzura neza amazi anyura kuri -196°C kugira ngo umusaruro ube mwizaIbisabwa ku isuku y'ibicuruzwa bya ASU (99.999% ku rwego rw'ikoranabuhanga) bisaba kugenzura neza amazi anyuramo. Womic yatanze valves zo mu bwoko bwa globe zifite intebe za PCTFE na disiki za Stellite zikomeye kugira ngo zigire imiterere ihamye yo gufunga. Valve zose 120 zatsinze ikizamini cya cryogenic nta gusohoka kwabyo.
2. Uburyo bwo kuvura umubiri wa CF3M mu buryo bwimbitseImibiri ya CF3M yakuwe mu gitereko ishobora kwangirika na austenite yagumyeho. Womic yavuwe mu buryo butatu mu buryo bwimbitse (-196°C, amasaha 12 kuri buri ruziga). Gusubiramo igenzura ry’imiterere y’imibiri byemejwe ko nta guhindagurika kwabyo.
3. Gupakira imyuka ihumanya ikirere idafite ingufu nyinshi kugira ngo ikoreshwe mu gutanga ogisijeniSerivisi ya ogisijeni isaba isuku ikomeye no gupakira imyuka ihumanya ikirere. Womic yatanze ISO 15848-1 Class A packing irimo amavuta ajyanye na ogisijeni.
4. Igenzura ry’umuntu wa gatatu rikorwa na BVUmukiriya akeneye ikizamini cya Bureau Veritas. BV yatanze icyemezo mu minsi 10.
Ibisubizo:Kwagura ASU byatangiye neza. Valve zose 120 z’isi zikora ku gipimo cya -196°C zimaze amezi arenga 18 zikora kuri -196°C nta kibazo cyo kuyitaho.
