The heat preservation jacket design of storage tank, known as jacketed tank or insulation layer tank, make the jacket layer in the outside of the tank , within the tank , heating or cooling material inside the tank by dielectric. Apply a layer of metal jacket insulation valves in the valve body welding, through to the metal jacket into steam, heat conduction oil, cooling water, cooling air etc., make the dielectric of body under the condition of different temperature change, still can adjust to achieving the required temperature, have the effect of heating preservation or cold. Thus heat preservation valve in the petroleum, chemical, metallurgical, pharmaceutical and other kinds of system has been widely applied, effectively reduces the heat loss of the medium in pipeline, prevent the occurrence of crystallization medium, solidification and other alike. Solve the production in the process of using too much hot or cold loss、 noisy pollution, realize the control of temperature during environment and equipment, and the staff have been further protection as well .
The design of jacketed tank, bring a great Gospel production for industry have the special requirements of processing process of tanks within the medium temperature, especially food processing areas, most of the microbial colony needs constant temperature fermentation period of environment has been more convenient to meet.
