Ukuqonda Ama-valve E-Bellow Seal Globe
Aivalvu yeglobhu yokuvala uphawu oluphansiiyivalvu ekhethekile yokuvala eyenzelwe ukuqeda ukuvuza kwesiqu ezicelweni ezibalulekile. Ngokungafani namavalvu e-globe ahlanganisiwe endabuko, isebenzisa i-metallic bellows assembly ehlanganiswe kokubili emzimbeni wesiqu kanye nevalvu, okwenza uphawu olungenawo umoya. Lo mklamo ubalulekile ekuphatheni imidiya enobuthi, egqwalisayo, noma ehlanzekile kakhulu lapho ukukhishwa kwegesi okusabalele kungamukeleki.
Izingxenye Eziyinhloko Zama-Bellow Seal Globe Valve
1. Ukuhlanganiswa Kwezimbongolo
- Izinto:Insimbi engagqwali (SS316/316L), Inconel 625, noma iHastelloy C276
- Umklamo:Ama-convolutions amaningi (izendlalelo ezingu-8-12) ukuze kube nokuqina komjikelezo okungaphezu kuka-10,000
- Umsebenzi:Iyacindezela/iyanwebeka ngesikhathi sokusebenza kwe-valve ngenkathi igcina ubuqotho besivalo
2. Umzimba Wevalvu
- Isilinganiso Sokucindezela:Ibanga 150 kuya ku-2500 (ANSI/ASME B16.34)
- Ukuxhumana Kokuphela:I-Flanged (RF/RTJ), i-socket weld, noma i-buttweld
- Ibanga Lokushisa:-196°C kuya ku-550°C (ukushisa okushisayo kuya kokushisa okuphezulu)
3. Isiqu kanye neDiski
- Ukuhlanganiswa kwe-stem-disc okuhlanganisiwe okuhlanganisiwe ukuze kulungiswe
- Ukuqina komphezulu (i-Stellite 6 coating) yokumelana nokuguguleka
4. Isivalo Sesibili (Isipele)
- Izindandatho zokupakisha ze-Graphite ngaphansi kwe-bellows njengeziphephile
Isebenza Kanjani I-Bellow Seal Globe Valve
Isinyathelo 1: Ukuvula iValve
Uma isondo lesandla lijikeleziswa ngokuphambene newashi:
- Isiqu siyaphakama, siphakamisa idiski esihlalweni
- Ama-Bellow acindezela i-axial, agcina ubuqotho besivalo
Isinyathelo 2: Ukuvala iValve
Ukujikeleza ngokwewashi:
- Amandla esiqu aphikisana nesihlalo, avimba ukugeleza kwamanzi
- Ama-Bellow anwebeka aze abe ubude bokuqala
Isinyathelo 3: Ukuvimbela Ukuvuza
Isenzo sokuvala kabili:
- Isivalo esiyinhloko: Indlela yokuvuza kwesiqu se-Bellows block
- Uphawu lwesibili: Ukupakisha i-Graphite (okuhambisana ne-API 622)
Izinzuzo Ngaphezu Kwama-Globe Valve Ajwayelekile
| Isici | I-Bellow Seal Globe Valve | I-Globe Valve Egcwele |
|---|---|---|
| Ukuvuza Kwesiqu | Ukukhishwa kweqanda elingekho (ISO 15848-1 TA-Luft) | Ukuvuza kufika ku-500 ppm |
| Ukulungiswa | Akukho ukushintshwa kokupakisha okudingekayo | Ukulungiswa kokupakisha kwaminyaka yonke |
| Izicelo | Izinhlelo zokuhlanza eziyingozi, ezihlanzekile kakhulu, | Izinsizakalo zamanzi/zomusi ezijwayelekile |
Izicelo Zezimboni
1. Ukucubungula Amakhemikhali
- Izitshalo ze-chlor-alkali (ukugcinwa kwegesi ye-chlorine)
- Ukukhiqizwa kwe-Pharmaceutical API
2. Uwoyela negesi
- Amayunithi e-HF alkylation
- Ukudluliselwa kwe-LNG cryogenic (-162°C)
3. Ukukhiqizwa Kwamandla
- Ukuhlukaniswa kwamanzi okuphakelwa kwebhoyila
- Izinhlelo zokudlula i-turbine yomusi
Izindlela Zokukhetha
1. Uhlobo lwe-Bellows
- Izimbongolo Ezihlanganisiwe:Umfutho Ophezulu (Isigaba se-ASME 1500+)
- Izinsimbi Ezihlanganisiwe:Imidiya egqwalisayo (ukuphela okupholishiwe ngogesi)
2. Izici Zokugeleza
- Ukugeleza okulinganayo kwephesenti uma kuqhathaniswa nokuqondile kwezinhlelo zokusebenza zokulawula
3. Izitifiketi
- I-NACE MR0175 yesevisi emuncu
- I-PED 2014/68/EU yezimakethe zaseYurophu
Abakhiqizi Abaphezulu Be-China Bellow Valve
Abakhiqizi baseShayina abanjengo-NSW Valve Abakhiqizi banikeza:
- Imiklamo ehambisana ne-API 602/BS 1873
- Ukonga izindleko okungu-30% uma kuqhathaniswa nemikhiqizo yaseYurophu
- Ukuhlolwa kwe-bellows ngokwezifiso (ukutholwa kokuvuza kwe-helium)
Izindlela Ezinhle Zokunakekela
- Ukuhlolwa kwe-bellows minyaka yonke ukuze kutholakale imifantu yokukhathala
- Ukugcotshwa kwesiqu ngamafutha okushisa okuphezulu
- Gwema ukushiswa ngokweqile (ubuningi be-50 Nm kuma-valve e-DN50)
