1、產品特點Features |
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中熱量損失。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。 The product bears favorable heat-prserviton and cold-insulation specialties. Inaddition, the all-diameter of the valve is identical to pipe diaeter to effectively reducethe heat loss from those medium in the pipelines. It is maimly applied to transport the full-bodyed mediums which solidify under normal temerature in such fields as perroleum industry, chemical industry, metallurgical industry, pharmaceutical industry, food industry, etc. For the monolithic constrution is applied in deaign the product, the jacket valve with favorable sealing performance features smaller configuration and weight than traditional ball valves without leakage. More overpressure-resistant and firme capacities are also enjoyed by the jacket made through carbon steel welding than through casting. |
