Valve Stem agịga na-enwe nrụgide

Needle Valve Stem nke nrụgide dị elu bụ ihe njikwa nrụba nke ziri ezi emebere maka ngwa ngwa na nhazi valve ruru 6,000 PSI (414 bar). Mepụtara site Ningbo Ruican iji itinye ego nkedo technology na 17-4 PH ọdịda-hardening igwe anaghị agba nchara, a akụrụngwa anapụta elu imecha, eri nkenke, na conical oche ziri ezi chọrọ maka afụ-ike shutoff na-achọ mmanụ & gas, petrochemical, na ike ọgbọ gburugburu. Usoro ihe nkedo agbakwunyere + CNC na-eme ka ogbe geometry na-agbanwe agbanwe mgbe ọ gachara, dị oke mkpa maka njirimara mgbaghari ugboro ugboro yana ndụ ogologo oche.

Usoro nrụpụta

1. Ihe Nlereanya Injection : Ngwunye wax mmiri mmiri na ígwè na-anwụ anwụ, ọnụ ọnụ conical kpụrụ ka ± 0.05mm
2. Ihe owuwu Shell : shei seramiiki oyi akwa 7-9 nwere mkpuchi silica isi maka imecha elu elu
3. Dewaxing & Agba : Autoclave dewaxing na 8 mmanya, shei na-agba na 950ºC
4. Ịwụ : 17-4 PH igwe anaghị agba nchara wụsara na 1560-1600C n'okpuru argon shroud
5. Ngwọta Ngwọta : 1040 ° C maka awa 1, ikuku dị jụụ
6. Mmiri mmiri ozuzo (H1025) : 550C maka awa 4, ikuku jụrụ.
7. CNC Machining : CNC ntụgharị nke eri (M16 x 1.5), oche conical (20° gụnyere akụkụ, Ra 0.4), na ndu ndu.
8. Ọgwụgwọ dị n'elu : Electropolishing ma ọ bụ passivation kwa ASTM A967
9. Nyocha : akụkụ CMM, ịdị nro elu, penetrant agba, ule ike

Atụmatụ igodo

• Ihe ike dị elu : 17-4 PH na-enweta ike 1070 MPa na ike 35-42 HRC, dabara maka valvụ 6,000 PSI.
• Oche conical nkenke : 20° cone akuku arụnyere na Ra 0.4 µm, na-eme ka akara afụ igwe kwụgidere nchara na ọla
• Eriri eri : M16 x 1.5 eri arụnyere na 6g nnabata maka ezigbo actuation na-enweghị azụ azụ
• Nguzogide corrosion : Passivated 17-4 PH na-enye ezigbo nguzogide H₂S, CO₂, na chloride gburugburu.
• Ngwunye elu : Ra 0.8 µm n'elu akara akara, Ra 1.6 µm n'ahụ - dị mma maka valvụ ọkwa akụrụngwa.
• NACE MR0175 kwadoro : Ọ dị na ọnọdụ NACE kwadoro maka ngwa ọrụ utoojoo

Mpaghara ngwa

• Ngwa valves agịga (klaasị 6,000 PSI)
• Usoro nchịkwa agịga valves maka petrochemical osisi
• Ihe mgbochi valvụ na-agba ọbara
• valvụ dịpụrụ adịpụ hydraulic nrụgide dị elu
• Ike osisi sampling sistem valves
• Usoro ikpo okwu dị n'ụsọ osimiri dịpụrụ adịpụ

Ihe kpatara ịhọrọ Ningbo Ruican

Ningbo Ruican si itinye ego nkedo nka na 17-4 PH igwe anaghị agba nchara, jikọtara ya na IATF 16949 àgwà usoro, na-anapụta valvụ components na izute API 602 na ASME B16.34 chọrọ. Igwe eji arụ ọrụ CNC anyị agbakwunyere na-eme ka ị nweta concentricity n'ime 0.02mm, dị oke mkpa maka ndụ okirikiri valvụ. Anyị na-enye asambodo ihe zuru oke (3.1 EN 10204), akwụkwọ nnabata NACE, yana PPAP maka iwebata ngwaahịa ọhụrụ.
