| 1、产品特点Features |
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中热量损失。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。
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. |
