保溫夾套球閥 BQ41F
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(you)于采(cai)用整體式(shi)結構，因而保(bao)溫球(qiu)閥(fa)比(bi)一般球(qiu)閥(fa)體積更(geng)小，重量更(geng)輕，且無外漏,密封性能良(liang)好，夾套采(cai)用碳(tan)素鋼管焊(han)接比(bi)鑄造的更(geng)加耐壓牢(lao)固。
Features
The product bears favorable heat-preservation and 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 and weight than traditional ball valves without leakage. More overpressure-resistant and firmer capacities are also
enjoyed by the jacket made through carbon steel welding than that through casting.
