High-Pressure Needle Valve Stem

Iyo High-Pressure Needle Valve Stem inonyatso kuyerera yekudzora chikamu chakagadzirirwa chiridzwa uye kugadzirisa mavharuvhu maapplication akaiswa kusvika ku6,000 PSI (414 bar). Yakagadzirwa naNingbo Ruican vachishandisa tekinoroji yekukanda mari mu17-4 PH kunaya-kuomesa simbi isina tsvina, chikamu ichi chinoburitsa kupedzisa kwepamusoro, shinda chaiyo, uye conical zvigaro zvekugara zvinodikanwa kuti bubble-tight shutoff mukuda oiri & gasi, petrochemical, uye kugadzirwa kwemagetsi nharaunda. Iyo yakabatanidzwa yekukanda + CNC machining process inovimbisa inowirirana stem geometry batch mushure mebatch, yakakosha kune inodzokororwa kuyerera maitiro uye hupenyu hurefu hwechigaro.

Manufacturing Process

1. Jekiseni rewakisi : Jekiseni rewakisi rine simbi rinofa, muromo wakaumbwa kusvika ±0.05mm
2. Kuvaka Shell : 7-9 layer ceramic shell ine fused silica primary jasi repamusoro pepamusoro pekupedzisira
3. Dewaxing & Kupfura : Autoclave dewaxing pa8 bar, shell pfuti pa950 ° C.
4. Kudururira : 17-4 PH simbi isina tsvina yakadururwa pa1560-1600 ° C pasi pechifukidzo cheargon
5. Kugadzirisa Kurapa : 1040 ° C kweawa imwe, mhepo yakanyoroveswa
6. Kunaya Kuoma (H1025) : 550°C kwemaawa mana, mweya wakatonhodzwa
7. CNC Machining : CNC kutendeuka kweshinda (M16 x 1.5), conical chigaro (20 ° inosanganisira angle, Ra 0.4), uye stem guide
8. Kurapa Kwepamusoro : Electropolishing kana passivation paASTM A967
9. Kuongorora : CMM dimensional, kushata kwepamusoro, dhayi inopinda, kuomarara bvunzo

Key Features

• Yakakwirira-Simba Material : 17-4 PH inowana 1070 MPa tensile simba uye 35-42 HRC kuomarara, yakakodzera 6,000 PSI yakarongerwa mavharuvhu.
• Precision Conical Seat : 20° koni yekona yakagadzirwa kusvika kuRa 0.4 µm, ichisimbisa simbi-kune-simbi chisimbiso.
• Thread Kurongeka : M16 x 1.5 shinda yakashongedzwa kusvika ku6g kushivirira kune yakatsetseka actuation pasina backlash
• Corrosion Resistance : Passivated 17-4 PH inopa yakanakisa kuramba kune H₂S, CO₂, uye chloride nharaunda.
• Surface Finish : Ra 0.8 µm panzvimbo yekuisa chisimbiso, Ra 1.6 µm pamuviri - yakanakira mavharuvhu egiredhi
• NACE MR0175 Inopindirana : Inowanikwa muNACE-inoenderana nemamiriro ekushandisa sour service application.

Minda Yekushandisa

• Instrumentation mavharuvhu etsono (6,000 PSI kirasi)
• Maitiro ekudzora tsono mavharuvhu e petrochemical zvirimwa
• Vhara uye kubuda ropa mavharuvhu akawanda
• High-pressure hydraulic isolation valves
• Simba rekudyara sampling system mavharuvhu
• Offshore platform process process yekuzviparadzanisa nevamwe

Sei Sarudza Ningbo Ruican

Ningbo Ruican's investment casting inyanzvi mu17-4 PH simbi isina tsvina, yakasanganiswa neIATF 16949 masisitimu emhando, inopa zvikamu zvevharuvhu zvinosangana neAPI 602 uye ASME B16.34 zvinodiwa. Yedu yakabatanidzwa CNC machining inovimbisa stem concentricity mukati me 0.02mm, yakakosha kuhupenyu hwevhavhavha. Isu tinopa yakazara zvinhu certification (3.1 EN 10204), NACE kutevedzera zvinyorwa, uye PPAP yekusuma chigadzirwa chitsva.
