When the transmission pipeline needs to be laid outdoors, most of them will be wrapped with a device for thermal insulation protection on the outer wall of the pipeline. The valves installed in the pipeline also need to be wrapped and insulated. The valve insulation cover is a kind of insulation material used for valves, which is designed to reduce heat loss and improve the energy efficiency of the system. This insulation cover is usually composed of multiple layers of materials, including an outer layer, an insulation layer and an inner layer.
