| 一體式保溫球閥產(chǎn)品特點(diǎn) 該產(chǎn)品具有良好的保溫保冷特性,且閥門的通徑與管徑*,同時(shí)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(huì)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(wú)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 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. 技術(shù)規(guī)范Technical Specification
