Isiqu seValve yoxinzelelo oluphezulu

I-High-Pressure Needle Valve Stem yicandelo lokulawula ukuhamba ngokuchaneka okwenzelwe izixhobo kunye nenkqubo ye-valve izicelo ezilinganiswe ukuya kwi-6,000 PSI (i-414 bar). Yenziwe nguNingbo Ruican isebenzisa itekhnoloji yotyalo-mali kwi-17-4 PH imvula-yenza lukhuni intsimbi, eli candelo lihambisa umphezulu, ukuchaneka komsonto, kunye nokuchaneka kwendawo yokuhlala efunekayo ukuze uvale i-bubble-tight kwi-oyile kunye negesi, i-petrochemical, kunye neendawo zokuvelisa amandla. Inkqubo edibeneyo yokuphosa + ye-CNC yomatshini iqinisekisa i-batch ye-jiometry ye-stem engaguqukiyo emva kwebhetshi, ibaluleke kakhulu kwiimpawu zokuhamba okuphindaphindiweyo kunye nobomi obude besihlalo.

Iinkcukacha zezinto eziphathekayo

Inkqubo yokuVelisa

1. Isitofu sepateni yeWax : Inaliti yewax elulwelo enentsimbi iyafa, incam econical yenziwe ukuba ibe yi ±0.05mm
2. Ulwakhiwo lweShell : 7-9 umaleko weqokobhe leceramic kunye nedyasi yesilica edityanisiweyo yokugqiba umgangatho ophezulu
3. Ukukhupha i-Dewaxing kunye nokudubula : I-autoclave dewaxing kwi-8 bar, iqokobhe lidubula kwi-950 ° C.
4. Ukugalela : 17-4 PH insimbi engenasici egalelwe kwi-1560-1600 ° C phantsi kwe-argon shroud
5. Unyango lwesisombululo : 1040 ° C ngeyure eli-1, umoya upholile
6. Ukuqina kwemvula (H1025) : 550 ° C kwiiyure ze-4, umoya upholile
7. I-CNC Machining : I-CNC yokuguqula intambo (M16 x 1.5), isihlalo se-conical (i-20 ° ifakwe i-angle, i-Ra 0.4), kunye ne-stem guide
8. Unyango loMphezulu : Ukwenziwa kombane okanye ukupasa nge-ASTM A967 nganye
9. Ukuhlolwa : Ubukhulu be-CMM, uburhabaxa bomphezulu, ukungena kwedayi, uvavanyo lobulukhuni

Ezona mpawu

• Izinto zoMmandla oPhezulu : I-17-4 PH ifezekisa i-1070 MPa yamandla okuqina kunye ne-35-42 HRC ubulukhuni, ilungele i-6,000 PSI i-valve elinganiselwe
• I-Precision Conical Seat : I-engile ye-cone eyi-20 ematshini eya kwi-Ra 0.4 µm, iqinisekisa ukutywinwa kwentsimbi ukuya kwintsimbi.
• Ukuchaneka koMsonto : I-M16 x 1.5 intambo eyenziwe ngomatshini ukuya kwi-6g yokunyamezelana ukuze isebenze kakuhle ngaphandle kokubuyela umva
• Ukumelana nokonakala : I-Pasivated 17-4 PH inika ukuchasana okugqwesileyo kwi-H₂S, i-CO₂, kunye neendawo zekloridi
• Ukugqitywa komphezulu : iRa 0.8 µm kwindawo yokutywina, iRa 1.6 µm emzimbeni - ilungele iivalvu zomgangatho wesixhobo
• I-NACE MR0175 Iyahambelana : Iyafumaneka kwimeko ehambelana ne-NACE kwizicelo zenkonzo emuncu

Iinkalo zeSicelo

• Iivalvu zeenaliti zesixhobo (iklasi ye-PSI eyi-6,000)
• Iivalvu zeenaliti zokulawula inkqubo yezityalo zepetrochemical
• Iindlela ezininzi zokuvala kunye nevalve yokuphuma kwegazi
• Iivalvu zokuzihlukanisa ze-hydraulic zoxinzelelo oluphezulu
• Iivalvu zenkqubo yesampula yeplanti yamandla
• Inkqubo yokwahlulwa kweqonga elingaphesheya

Kutheni ukhetha uNingbo Ruican

Ubuchwephesha bokuphosa utyalo-mali luka-Ningbo Ruican kwi-17-4 PH yensimbi engenasici, edityaniswe ne-IATF 16949 yeenkqubo zomgangatho, ihambisa amacandelo evalvu ahlangabezana neemfuno ze-API 602 kunye ne-ASME B16.34. Umatshini wethu odibeneyo we-CNC uqinisekisa ukugxila kwesiqu ngaphakathi kwe-0.02mm, ibaluleke kakhulu kubomi bomjikelezo wevalvu. Sibonelela ngesiqinisekiso esipheleleyo sezinto ezibonakalayo (3.1 EN 10204), amaxwebhu okuthotyelwa kwe-NACE, kunye nePPAP yokwazisa imveliso entsha.
