Working principle of integrated heat preservation ball valve:
The integral heat preservation ball valve is used to weld metal jacket on the basis of ball valve, which is used to inject steam or other heat preservation and cold keeping medium to ensure the medium in the valve can work normally. It has good insulation and cold protection characteristics, and the valve diameter and pipe diameter are consistent, but also can effectively reduce the heat loss of medium in the pipeline. The insulation jacket ball valve adopts the integral jacket structure design, more uniform insulation and cold preservation, heat preservation ball valve is smaller than the general ball valve, lighter weight, and no leakage, sealing performance is good, jacket with carbon steel pipe welding, more stable than the casting. The jacket and the outer side of the valve are welded with the jacket nozzle, allowing the maximum pressure of steam or cold water to be 1MPa.
Product features of integrated heat preservation ball valve:
1, the integral heat preservation ball valve has good insulation and cooling characteristics, and the valve diameter and diameter consistent, but also can effectively reduce the medium heat loss in the pipeline.
2, widely used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems, in order to transport at room temperature will be solidified high viscosity medium.
3, due to the use of an integral structure, so the ball valve is smaller than the general ball valve, lighter weight, and no leakage, sealing performance is good, jacket with carbon steel pipe welding, more stable than the casting.
