BQ41F Insulation Jacket Wafer Connecting Ball Valve

Introduction of BQ41F insulation jacketed ball valve:

BQ41F thermal insulation jacketed ball valve, also known as jacketed ball valve, is a metal jacket welded on the basis of the ball valve, which is used to inject steam or other thermal insulation and cooling medium to ensure that the medium in the valve can work normally. The thermal insulation jacketed ball valve has good thermal insulation and cold insulation characteristics, and the diameter of the valve is consistent with the diameter of the pipe, and at the same time, it can effectively reduce the heat loss of the medium in the pipeline. According to the structure of the ball valve, the thermal insulation ball valve has several structural forms, such as integral thermal insulation ball valve, two-piece thermal insulation ball valve, and wafer thermal insulation ball valve.

BQ41F thermal insulation jacketed ball valve is smaller in volume and lighter in weight than ordinary ball valves, and has no leakage and good sealing performance.

BQ41F insulation jacketed ball valve application range:

BQ41F thermal insulation jacketed ball valve 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.

Structural features of BQ41F insulation jacketed ball valve:

BQ41F thermal insulation jacketed ball valve adopts integral jacket structure design, which can keep warm and cold more evenly. The thermal insulation ball valve is smaller in volume and lighter in weight than ordinary ball valves, and has no leakage and good sealing performance. The jacket is welded with carbon steel pipe. Stronger and more pressure-resistant than casting. The jacket, the outside of the valve body and the jacket pipe are welded, and the maximum pressure allowed for steam or cold water is 1MPa.

The thermal insulation ball valve has good thermal insulation and cold insulation characteristics. Except for the reduced diameter thermal insulation ball valve, the diameter of the valve is the same as the diameter of the pipe, the medium flows in a straight line, and the resistance is small, which can effectively reduce the heat loss of the medium in the pipeline. Therefore, it is easy to solidify. , High viscosity liquid medium has excellent performance.
