Setsi sa Valve ea Nale ea Khatello e Phahameng

The High-Pressure Needle Valve Stem ke karolo e nepahetseng ea ho laola phallo e etselitsoeng lisebelisoa le lisebelisoa tsa li-valve tse lekantsoeng ho fihlela ho 6,000 PSI (414 bar). E entsoe ke Ningbo Ruican e sebelisa theknoloji ea ho etsa matsete ka tšepe ea 17-4 PH e thatafatsang pula e sa hloekang, karolo ena e fana ka boleng bo holimo, ho nepahala ha likhoele, le ho nepahala ha litulo tse hlokahalang bakeng sa ho koala sekheo sa oli le khase, petrochemical, le tikoloho ea phepelo ea matla. Ts'ebetso e kopaneng ea ho lahla + CNC e etsa bonnete ba hore batch ea geometry ea stem e sa fetoheng kamora batch, e bohlokoa bakeng sa litšobotsi tsa phallo e phetoang le bophelo bo bolelele ba setulo.

Litlhaloso tsa Lintho

Mokhoa oa Tlhahiso

1. Ente ea Wax Pattern : Ente ea boka ea metsi e nang le tšepe ea shoa, ntlha e kholo e entsoe ho ± 0.05mm
2. Mohaho oa khetla : khetla ea ceramic ea 7-9 e nang le seaparo sa mantlha sa silica se kopantsoeng bakeng sa ho qeta holimo holimo
3. Dewaxing & Firing : Autoclave dewaxing ho 8 bar, shell e thunya ka 950 ° C.
4. Ho tšela : 17-4 PH tšepe e sa hloekang e tšeloa ka 1560-1600 ° C tlas'a sekoahelo sa argon
5. Tharollo Phekolo : 1040 ° C bakeng sa hora ea 1, moea o pholile
6. Ho thatafatsa ha pula (H1025) : 550°C bakeng sa lihora tse 4, moea o pholile
7. CNC Machining : CNC turning of thread (M16 x 1.5), conical seat (20° kenyelelitsoe angle, Ra 0.4), le stem guide
8. Kalafo ea Bokaholimo : Electropolishing kapa passivation ka ASTM A967
9. Tlhahlobo : CMM dimensional, bokaholimo ba bokaholimo, dae e kenang, teko ea boima

Likarolo tsa Bohlokoa

• Lintho tse Matla a Phahameng : 17-4 PH e fihlella matla a 1070 MPa le boima ba 35-42 HRC, e loketseng li-valve tsa 6,000 tsa PSI
• Precision Conical Seat : 20° cone angle has machined to Ra 0.4 µm, ho netefatsa tiiso ea tšepe ho isa ho tšepe
• Ho nepahala ha Khoele : Khoele ea M16 x 1.5 e entsoe ka mamello ea 6g bakeng sa ts'ebetso e boreleli ntle le backlash
• Corrosion Resistance : Passivated 17-4 PH e fana ka khanyetso e ntle ho H₂S, CO₂, le tikoloho ea chloride
• Surface Finish : Ra 0.8 µm holim'a ho tiisa, Ra 1.6 µm 'meleng - e loketse li-valve tsa boemo ba lisebelisoa
• E lumellana le NACE MR0175 : E fumaneha maemong a lumellanang le NACE bakeng sa lits'ebetso tsa ts'ebeletso e bolila

Libaka tsa Kopo

• Li-valve tsa nale ea lisebelisoa (6,000 PSI sehlopha)
• Li-valve tsa lisebelisoa tsa ho laola mekhoa bakeng sa limela tsa petrochemical
• Li-valve tse ngata tse thibelang le ho tsoa mali
• Li-valve tsa ho itšehla thajana tsa hydraulic tsa khatello e phahameng
• Li-valve tsa tsamaiso ea lisampole tsa semela sa motlakase
• Offshore platform process process ho itšehla thajana

Hobaneng U Khetha Ningbo Ruican

Bokhoni ba Ningbo Ruican ba ho etsa matsete ka tšepe ea 17-4 PH, e kopantsoeng le lits'ebetso tsa boleng tsa IATF 16949, e fana ka likarolo tsa valve tse fihlelang litlhoko tsa API 602 le ASME B16.34. Mechini ea rona e kopaneng ea CNC e tiisa hore stem concentricity ka har'a 0.02mm, e bohlokoa bakeng sa bophelo ba potoloho ea li-valve. Re fana ka setifikeiti se felletseng sa thepa (3.1 EN 10204), litokomane tsa tumellano ea NACE, le PPAP bakeng sa kenyelletso e ncha ea sehlahisoa.
