Insulated stop valve
I. Introduction:
The insulation stop valve is mainly used in various systems such as petroleum, chemical, metallurgical, and pharmaceutical industries to transport high-viscosity media that solidify at room temperature. It is a BJ45W straight-through jacketed insulation stop valve. The insulation jacket is welded between the two flanges of the valve, and two connection ports for the insulation jacket are provided on the side and bottom of the valve. The straight-through insulation stop valve is especially suitable for pipelines in the fertilizer industry. The steam introduced into the jacket can prevent the medium from crystallizing. The insulation valve is formed by welding a layer of metal jacket on the valve body. By injecting steam, heat transfer oil, cooling water, cold water, etc. into the metal jacket, the medium in the valve body can reach the required temperature under conditions such as room temperature, temperature rise, and temperature drop, thus playing the role of heat preservation or cold preservation. The insulation valve is used for high-viscosity media, steam, or other heat-preserving or cold-preserving media that solidify at room temperature, ensuring that the medium inside the valve can work normally.
II. Working Principle:
The insulation valve has excellent heat preservation and cold preservation characteristics, and its diameter matches the pipe diameter. At the same time, it can effectively reduce the heat loss of the medium in the pipeline. It has excellent heat preservation and cold preservation characteristics, and at the same time can effectively reduce the heat loss of the medium in the pipeline. Insulation valves are widely used in various systems such as petroleum, chemical, metallurgical, and pharmaceutical industries. They effectively reduce the heat loss of the medium in the pipeline and prevent phenomena such as medium crystallization and solidification. The function of the insulation valve is that when the medium passes through the valve under high or low temperature conditions, the medium inside the insulation valve provides a heat preservation effect, preventing the medium from condensing or sticking to the inside of the valve body, so that the valve can open and close normally.
