BQ41H一體式保溫球閥產(chǎn)品特點 該產(chǎn)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(zhì)熱量損失。主要用于石油、化工、冶金、制藥、食品等各類系統(tǒng)中，以輸送常 溫下會凝固的高粘度介質(zhì)。 由于采用整體式結(jié)構(gòu)，因而保溫球閥比一般球閥體積更小，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。 Features The product bears favorable heat-preservation.cold-insulation specialties.In addition, the all-diameter of the valve is identical to pipe diameter to effectively reduce the heat loss from those medium in the pipeline. It is mainly applied to transport the full- bodied mediums which solidify under normal temperature in such fields as petroleum industry, chemical industry, metallurgical industry, pharmaceutical industry,food industry, etc. For the monolithic construction is applied in design the product, the jacket valve with favorable sealing performance features smaller configuration.weight than traditional ball valves without leakage. More overpressure-resistant.firmer capacities are also enjoyed by the jacket made through carbon steel welding than that through casting. 技術規(guī)范Technical Specification 設計標準 Design Standard ASME B 16.34 GB/T 12224 結(jié)構(gòu)長度 Structure length ASME B 16.10 GB/T 12221 連接法蘭 Connecting flange ASME B 16.5 JB/T 79 驅(qū)動方式 Driving manner 手動、電動、氣動 Manual,Moton driving,Pneumatil 試驗和檢驗 Test & Inspection JB/T9092 API 598 適用介質(zhì) Applicable medium 重油、膠類等易凝固介質(zhì) Heavy oil,glue.other easy-clotting medium 主要零件材質(zhì)表Form of Major Parts Materials 序號 零件名稱 Accessory name 材 質(zhì) Material GB ASTM 1 夾套 Jacket 25 A105 2 閥座 Seat WCB A216-WCB 3 閥體 Body 25 A105 4 密封圈 SealingRing PTFE、對位聚苯 PTFE、Counterpoint polypheny1 5 球體 Ball 6 閥桿 Stem 1Cr13 A247-410 7 填料 Stuffing 柔性石墨 Graphite 8 填料壓蓋 Gland WCB A216-WCB 注：系列閥門主要零部件及密封面的材質(zhì)可根據(jù)實際工況條件或用戶特殊要求設計選用.
