Insulation characteristics of pneumatic valve ball 1)

it is also called heat preservation jacket pneumatic ball valve, pneumatic ball valve on the basis of the weld metal sheath used for injecting steam or other heat, cold medium, medium, in order to ensure the normal operation of the pneumatic valve. Insulation pneumatic ball valve according to the different structures, but also the whole insulation ball pneumatic valve, two plate heat preservation, pneumatic valve, ball ball in several structure, heat preservation performance good cold pneumatic ball valve with pneumatic valves, pneumatic clamp type valves of the same diameter and diameter, and the media can effectively reduce the pipe heat loss. Mainly used in oil, chemical, metallurgical, pharmaceutical, food and other types of transportation systems will be solidified at room temperature, but also high viscosity medium. Ball has good thermal insulation, cold insulation performance, in addition to reducing thermal pneumatic valve, pneumatic valve diameter and a linear flow resistance of medium diameter, which can effectively reduce the heat loss of pipe media, therefore, easy solidified, good performance of high viscosity fluid. In addition to the two type thermal insulation pneumatic valve, pneumatic valve design in all use monolithic coat, more uniform heat, cold. Jacket, with external body welding, steam or cold water jacket, maximum allowable stress MPa.
