Li-valve tsa Cryogenic ke eng: Mofuta, Tšebeliso (LNG, Bongaka)

1. Selelekela ho Li-valve tsa Cryogenic

Li-valve tsa cryogenicke di-valve tse entsweng ka ho kgetheha tse sebediswang ho laola phallo ya metsi le dikgase tse batang haholo, hangata dithempereichara tse ka tlase ho-40°C (-40°F)Li-valve tsena li bohlokoa haholo ts'ebetsong ea liindasterikhase ea tlhaho e metsi (LNG), naetrojene e metsi, oksijene, haeterojene le helium, moo di-valve tse tloaelehileng di neng di tla hloleha ka lebaka la kgatello ya mocheso, ho robeha ha thepa, kapa ho hloleha ha seal.

Ho netefatsa ts'ebetso e bolokehileng le e sebetsang hantle, li-valve tsa cryogenic li entsoe ka thepa e ikhethang, likutu tse atolositsoeng, le mekhoa e khethehileng ea ho koala ho mamella mocheso o tlase haholo ntle le ho lutla kapa ho hloleha ha mechini.

2. Litšobotsi tsa Bohlokoa tsa Sebopeho sa Li-valve tsa Cryogenic

Ho fapana le di-valve tse tloaelehileng, di-valve tsa cryogenic di kenyelletsa dikarolo tse ikgethang tsa moralo ho sebetsana le serame se feteletseng:

2.1 Bonnet e Atolositsoeng (Katoloso ea kutu)

- E thibela phetiso ea mocheso ho tloha tikolohong ho ea 'meleng oa valve, e fokotsa ho thehoa ha leqhoa.

- E boloka sephutheloana le actuator mochesong o tloaelehileng ho netefatsa ts'ebetso e boreleli.

2.2 Lisebelisoa tse Ikhethileng tsa ho Tiisa

- TšebelisoPTFE (Teflon), graphite, kapa litiiso tsa tšepeho boloka ho kwalwa ka thata esita le mochesong o batang haholo.

- E thibela ho dutla ha metsi, e leng ntho ea bohlokoa bakeng sa likhase tse kotsi tse kang LNG kapa oksijene e metsi.

2.3 Lisebelisoa tsa 'Mele tse Matla

- E entsoe katšepe e sa ruseng (SS316, SS304L), koporo, kapa metsoako ea nikeliho hanela ho robeha ha bonolo.

- Li-valve tse ling tse nang le khatello e phahameng li sebelisoatšepe e entsoeng ka maiketsetsobakeng sa matla a eketsehileng.

2.4 Ho Sireletsa ka Vacuum (E ka ikgethela bakeng sa Serame se Feteletseng)

- Li-valve tse ling li na le tšobotsilijakete tsa vacuum tse nang le marako a mabeliho fokotsa ho kenella ha mocheso lits'ebetsong tsa mocheso o tlase haholo.

3. Tlhophiso ea Li-valve tsa Cryogenic

3.1 Ka Mokhahlelo oa Mocheso

3.2 Ka Mofuta oa Valve

- Li-valve tsa Mabolo a Cryogenic– E molemohali bakeng sa ho tima kapele; e atile haholo lits'ebetsong tsa LNG le tsa khase ea indasteri.

- Li-valve tsa Heke ea Cryogenic– E sebediswa bakeng sa taolo e bulehileng/e kwalang ka botlalo ka ho theola kgatello hanyane.

- Li-valve tsa Globe tsa Cryogenic– Fana ka taolo e nepahetseng ea phallo liphaepheng tsa cryogenic.

- Li-valve tsa ho hlahloba Cryogenic– Thibela phallo e kgutlelang morao ditsamaisong tsa mocheso o tlase.

- Li-valve tsa Serurubele tse nang le Cryogenic– E bobebe ebile e nyane, e loketse liphaephe tse bophara bo boholo. 

3.3 Ka Kopo

- Li-valve tsa LNG– Sebetsana le khase ea tlhaho e metsi ho-162°C (-260°F).

- Lifofane le Tšireletso– E sebelisoa lits'ebetsong tsa mafura a rokete (haeterojene e metsi le oksijene).

- Bongaka le Saense– E fumaneha mechineng ea MRI le polokelong ea cryogenic.

- Tsamaiso ea Khase ea Liindasteri– E sebelisoa limela tse arolang moea (oksijene, naetrojene, argon).

4. Melemo ea Li-valve tsa Cryogenic

✔Tshebetso e Sireletsang ho Dutla– Ho kwala ho tsoetseng pele ho thibela ho dutla ha khase ho kotsi.

✔Bokgoni ba ho Futhumatsa– Li-bonnet tse atolositsoeng le thepa e sireletsang mocheso li fokotsa phetiso ea mocheso.

✔Ho tšoarella– Thepa ea boleng bo holimo e hanela ho petsoha le ho robeha habonolo.

✔Ho Latela Melao ea Polokeho– LikopanaASME, BS, ISO, le APIlitekanyetso tsa tšebeliso ea cryogenic.

✔Tlhokomelo e Tlase– E etselitsoe ho tšepahala ha nako e telele maemong a thata.

5. Liphapang tsa Bohlokoa Pakeng tsa Li-valve tsa Cryogenic le tse Tloaelehileng

Qetello

Li-valve tsa cryogenicli bohlokoa bakeng sa liindasteri tse sebetsanang le maro a mocheso o tlase haholo. Moralo oa tsona o ikhethang—o nang leli-bonnet tse atolositsoeng, litiiso tse sebetsang hantle, le thepa e tšoarellang—e netefatsa ts'ebetso e sireletsehileng le e sebetsang hantle maemong a feteletseng. Ho utloisisa lihlopha tsa tsona, melemo le liphapang ho tsoa ho li-valve tse tloaelehileng ho thusa ho khetha valve e nepahetseng bakeng sa lits'ebetso tse hlokang cryogenic.
