BQ941F electrical insulation ball valve
Product Name:
BQ941F electrical insulation ball valve
Description:

電動保溫球閥BQ941F

概述:
   該產品具有良好的保溫保冷特性,且閥門的通徑與管徑一致,同時又能有效降低管路中介質熱量損失。主要用于石油、化工、冶金、制藥、食品等各類系統中,以輸送常溫下會凝固的高粘度介質。
由于采用整體式結構,因而保溫球閥比一般球閥何種更小,重量更輕,且無外漏,密封性能良好,夾套采用碳素鋼管焊接比鑄造的更加耐壓牢固。
技術規范:
設計標準 ASME B 16.34 GB/T12224
結構長度 ASME B 16.10 GB/T12221
連接法蘭 ASME B 16.5、JB/T 79
驅動方式 手動、電動、氣動
試驗和檢驗 JB/T9092 API 598
適用介質 重油、膠類等易凝固介質
