美科BQ41H一体式保温球阀

BQ41H一体式保温球阀产品特点 该产品具有良好的保温保冷特性,且阀门的通径与管径一致,同时又能有效降低管 路中介质热量损失。主要用于石油、化工、冶金、制药、食品等各类系统中，以输送常 温下会凝固的高粘度介质。 由于采用整体式结构，因而保温球阀比一般球阀体积更小，重量更轻，且无外漏,密封性能良好，夹套采用碳素钢管焊接比铸造的更加耐压牢固。 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. 技术规范Technical Specification 设计标准 Design Standard ASME B 16.34 GB/T 12224 结构长度 Structure length ASME B 16.10 GB/T 12221 连接法兰 Connecting flange ASME B 16.5 JB/T 79 驱动方式 Driving manner 手动、电动、气动 Manual,Moton driving,Pneumatil 试验和检验 Test & Inspection JB/T9092 API 598 适用介质 Applicable medium 重油、胶类等易凝固介质 Heavy oil,glue.other easy-clotting medium 主要零件材质表Form of Major Parts Materials 序号 零件名称 Accessory name 材 质 Material GB ASTM 1 夹套 Jacket 25 A105 2 阀座 Seat WCB A216-WCB 3 阀体 Body 25 A105 4 密封圈 SealingRing PTFE、对位聚苯 PTFE、Counterpoint polypheny1 5 球体 Ball 6 阀杆 Stem 1Cr13 A247-410 7 填料 Stuffing 柔性石墨 Graphite 8 填料压盖 Gland WCB A216-WCB 注：系列阀门主要零部件及密封面的材质可根据实际工况条件或用户特殊要求设计选用.
