Ukuqonda i-Bellow Seal Globe Valves
Ai-valve ye-globe ye-bellow sealiyi-valve yokuvala ekhethekile eyenzelwe ukuqeda ukuvuza kwesiqu ezinhlelweni ezibucayi. Ngokungafani nama-valve embulunga apakishiwe endabuko, isebenzisa ukuhlanganiswa kwe-metallic bellows eshiselwe kuwo womabili umzimba we-stem kanye nama-valve, okwenza uphawu lwe-hermetic. Lo mklamo ubalulekile ekuphatheni imidiya enobuthi, ebolayo, noma ehlanzekile lapho ukukhishwa kwempumu kungamukeleki.
Izingxenye Ezibalulekile ze-Bellow Seal Globe Valves
1. Bellows Assembly
- Okubalulekile:Insimbi engagqwali (SS316/316L), Inconel 625, noma i-Hastelloy C276
- Idizayini:I-Multi-ply convolutions (izendlalelo ezingu-8-12) zokuqina komjikelezo ongu-10,000+
- Umsebenzi:Icindezela / inweba ngesikhathi sokusebenza kwe-valve ngenkathi igcina ubuqotho bophawu
2. Umzimba weValve
- Isilinganiso Sokucindezela:Ikilasi 150 ukuya ku-Class 2500 (ANSI/ASME B16.34)
- Qeda ukuxhumeka:I-Flanged (RF/RTJ), i-socket weld, noma i-buttweld
- Ibanga Lesikhathi:-196°C kuya ku-550°C (cryogenic kuya ekushiseni okuphezulu)
3. Isiqu & Idiski
- Ukuhlanganiswa kwe-stem-disc ehlanganisiwe ehlanganisiwe yokuqondanisa
- Ukuqina kobuso (i-Stellite 6 coating) yokumelana nemihuzuko
4. Uphawu Lwesibili (Isipele)
- Izindandatho zokupakisha ze-graphite ezingezansi njenge-fail-safe
Isebenza Kanjani I-Bellow Seal Globe Valve
Isinyathelo 1: Ukuvula i-Valve
Uma isondo lesandla lizungeziswa ngokuphambene newashi:
- Isiqu siyakhuphuka, siphakamise i-disc esihlalweni
- I-Bellows compress axially, igcina ubuqotho bophawu
Isinyathelo sesi-2: Ukuvala i-Valve
Ukuzungezisa ngokwewashi:
- I-stem iphoqa i-disc ngokumelene nesihlalo, imisa ukugeleza
- I-Bellow idlulela kubude bangempela
Isinyathelo sesi-3: Ukuvimbela Ukuvuza
Isenzo sokuvala kabili:
- Uphawu oluyinhloko: Indlela yokuvuza ye-Bellows block stem
- Uphawu lwesibili: Ukupakisha kwe-graphite (kuyahambisana ne-API 622)
Izinzuzo Ngamavalvu Ajwayelekile EGlobe
| Isici | I-Bellow Seal Globe Valve | Igcwele Globe Valve |
|---|---|---|
| Ukuvuza Kwesiqu | Ukukhishwa okunguziro okuphumayo (ISO 15848-1 TA-Luft) | Kufika ku-500 ppm ukuvuza |
| Isondlo | Akukho ukushintshwa kokupakisha okudingekayo | Ukugcinwa kokupakisha kwaminyaka yonke |
| Izinhlelo zokusebenza | Amasistimu ayingozi, ahlanzekile kakhulu, ane-vacuum | Izinsiza ezijwayelekile zamanzi/nomusi |
Izicelo zezimboni
1. Chemical Processing
- Izitshalo ze-Chlor-alkali (i-chlorine gas containment)
- Ukukhiqizwa kwe-Pharmaceutical API
2. Uwoyela Negesi
- HF alkylation amayunithi
- Ukudluliswa kwe-LNG cryogenic (-162°C)
3. Ukukhiqiza Amandla
- Ukuhlukaniswa kwamanzi okuphakelayo kwe-boiler
- Amasistimu wokudlula ama-Steam turbine
Imibandela Yokukhetha
1. Uhlobo lwe-Bellows
- Izinhlamvu eziqanjiwe:Ingcindezi ephezulu (ASME Class 1500+)
- Ama-Welded Bellows:Imidiya elimazayo (i-electropolished finish)
2. Izimpawu zokugeleza
- Amaphesenti alinganayo uma kuqhathaniswa nokugeleza komugqa wezinhlelo zokusebenza zokulawula
3. Izitifiketi
- I-NACE MR0175 yenkonzo emuncu
- I-PED 2014/68/EU yezimakethe zaseYurophu
Abakhiqizi Bevalve Abaphezulu baseChina
Abakhiqizi baseShayina abanjengomnikelo we-NSW Valve Manufacturer:
- Imiklamo ehambisana ne-API 602/BS 1873
- 30% ukonga kwezindleko uma kuqhathaniswa nemikhiqizo yaseYurophu
- Ukuhlola okungokwezifiso kokuvuza (ukutholwa kokuvuza kwe-helium)
Imikhuba Engcono Kakhulu Yesondlo
- Ukuhlolwa kwe-bellows kwaminyaka yonke ukuthola imifantu yokukhathala
- I-stem lubrication ngamafutha okushisa aphezulu
- Gwema i-torquing ngokweqile (ubukhulu obungu-50 Nm kumavalvu e-DN50)
