BQ41F Thermal sheath ball valve Thermal sheath ball valve has good thermal insulation and cold protection characteristics, and the diameter of the valve is the same as the pipe diameter, and can effectively reduce the heat loss of the medium in the pipeline. Thermal insulation ball valve according to the different structure of the ball valve, there are integral thermal insulation ball valve, two-piece thermal insulation ball valve, sandwich thermal insulation ball valve and other structural forms, widely used in chemical, petroleum, pharmaceutical, metallurgy and other industries of the system pipeline.
The insulated ball valve is smaller than the general ball valve, lighter weight, and no leakage, good sealing performance, the jacket is welded with carbon steel pipe than the cast more firmly resistant to pressure.
Ball valve with thermal insulation jacket is mainly used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems to transport heavy oil, glue and other high viscosity media that will solidify at room temperature.
Insulation jacket ball valve with integral jacket structure design, more uniform heat preservation, cold, insulation ball valve than the general ball valve smaller volume, lighter weight, and no leakage, sealing performance is good, the jacket using carbon steel pipe welding than casting more firm pressure. The jacket, the outer side of the valve body and the jacket nozzle are welded, allowing the maximum pressure of steam or cold water to 1MPa.
Thermal insulation ball valve has good thermal insulation, cold characteristics, in addition to reducing the diameter of the thermal insulation ball valve, the diameter of the valve and the diameter of the pipe, the medium is a straight line flow, the resistance is small, can effectively reduce the heat loss of the medium in the pipeline, therefore, easy to solidify, high viscosity of the liquid medium has excellent performance.
