Kunzwisisa Mavharuvhu eBellow Seal Globe
Avharuvhu yepasi pechisimbisoivharuvhu yakagadzirwa nehunyanzvi yakagadzirirwa kubvisa kubuda kwetsinga mumashandisirwo akakosha. Kusiyana nemavharuvhu epasi rose akarongwa, inoshandisa simbi yakasungirirwa kumudzi wetsinga nevharuvhu, zvichiita kuti ive seal inovharika. Dhizaini iyi yakakosha pakubata zvinhu zvine chepfu, zvinoparadza, kana kuti zvakachena zvakanyanya uko kusvibiswa kwemhepo kusingagamuchirwi.
Zvikamu Zvikuru zveBellow Seal Globe Valve
1. Kuungana kweBellows
- Zvinyorwa:Simbi isina ngura (SS316/316L), Inconel 625, kana Hastelloy C276
- Dhizaini:Makonzo ekubatanidza akawanda (8-12 layers) ekuchengetedza 10,000+ cycle
- Basa:Inodzvanya/inotambanudza panguva yekushanda kwevharuvhu uku ichichengetedza kuvimbika kwechisimbiso
2. Muviri weVharuvhu
- Kuyera Kumanikidzwa:Kirasi 150 kusvika Kirasi 2500 (ANSI/ASME B16.34)
- Kuguma Kwekubatana:Yakaputirwa (RF/RTJ), soketi yekubatanidza, kana kuti buttweld
- Range yeTemp:-196°C kusvika 550°C (kupisa kwakanyanya kusvika pakupisa kwakanyanya)
3. Dumbu neDisiki
- Musangano wekubatanidza stem-disc wakagadzirwa kuti ugadziriswe
- Kuomesa pamusoro (Stellite 6 coating) kudzivirira kukwenya
4. Chisimbiso Chechipiri (Backup)
- Mhete dzeGraphite dzinoiswa pasi pevhu sedzisina njodzi
Vharuvhu yeGlobe yeBellow Seal Inoshanda Sei
Danho 1: Kuvhura Valve
Kana vhiri reruoko rikatenderedzwa nenzira inopesana newachi:
- Hunde inosimuka, ichisimudza dhisiki kubva pachigaro
- Mvuto dzinodzvinya axially, dzichichengetedza kuvimbika kwechisimbiso
Danho rechipiri: Kuvhara Valve
Kutenderera kwewachi:
- Simba rehunde rinorwisa chigaro, richimisa kuyerera kwemvura
- Maburi anotambanukira pakureba kwepakutanga
Danho rechitatu: Kudzivirira Kubuda Kwemvura
Chiito chekuisa chisimbiso kaviri:
- Chisimbiso chikuru: Nzira yekubuda kwehunde inovhara gomba
- Chisimbiso chechipiri: Kurongedza Graphite (kutevedzera API 622)
Zvakanakira Pamusoro peMavharuvhu Epasi Pese
| Chinhu | Chisimbiso cheBlow Globe Valve | Vharuvhu yeGlobe Yakarongedzwa |
|---|---|---|
| Kubuda kweHunde | Zero fugitive emissions (ISO 15848-1 TA-Luft) | Kusvika ku500 ppm kubuda kwemvura |
| Kugadzirisa | Hapana chikonzero chekutsiva kurongedza | Kugadziriswa kwepakeji kwegore negore |
| Mashandisirwo | Masisitimu ane njodzi, akachena zvakanyanya, uye anobvisa mhepo | Mabasa emvura/mhepo yakawanda |
Zvikumbiro zveMaindasitiri
1. Kugadziriswa kweMakemikoro
- Miti yechlor-alkali (inochengetedza gasi rechlorine)
- Kugadzirwa kweMishonga API
2. Oiri neGasi
- HF alkylation mayuniti
- Kutamiswa kweLNG cryogenic (-162°C)
3. Kugadzira Magetsi
- Kuzviparadzanisa nemvura yebhoira
- Masisitimu ekupfuura neturbine yemhepo inoputika
Maitiro Ekusarudza
1. Rudzi rweMvuto
- Mvuto Dzakagadzirwa:Kumanikidzwa kwakanyanya (ASME Kirasi 1500+)
- Mvuto dzakasungirirwa:Midhiya inoparadza (kupedzisa kwakagadziriswa nemagetsi)
2. Hunhu hweKuyerera
- Kuyerera kwakaenzana kwehuwandu kana kuenzaniswa kwenzira dzekushandisa kudzora
3. Zvitupa
- NACE MR0175 yebasa rakaoma
- PED 2014/68/EU yemisika yeEurope
Vagadziri vepamusoro veChina Bellow Valve
Vagadziri vekuChina vakaita seNSW Valve Manufacturer vanopa:
- Magadzirirwo anoenderana neAPI 602/BS 1873
- Kuchengetedza mari ne30% zvichienzaniswa nemarudzi ekuEurope
- Kuongororwa kwemhepo yakagadzirwa (kuongorora kubuda kwemvura mu helium)
Maitiro Akanakisisa Ekugadzirisa
- Kuongororwa kwepagore kwega kwega kwekubvisa mavanga ekuneta
- Kuzora tsinde nemafuta anodziya zvakanyanya
- Dzivisa kutenderedza zvakanyanya (kusvika 50 Nm yemavharuvhu eDN50)
