Problems solved by technology
However, due to the existence of nano-powder as powder particles, when it is applied to thermal insulation materials, it is mostly made into thermal insulation boards for flat thermal insulation; it is not suitable for some pipes, kilns, etc. (such as valves) that need to be bent and wound.

Abstract
The invention relates to a nanometer heat insulation case for valve heat insulation. The nanometer heat insulation case is characterized by comprising a silica gel fabric layer and a glass fiber fabric layer, edges of the silica gel fabric layer and the glass fiber fabric layer are mutually connected, a cavity is formed between the silica gel fabric layer and the glass fiber fabric layer, and nanometer powder is filled in the cavity. The glass fiber fabric layer is 3-5mm in thickness, and the thickness of the nanometer powder is 10-30mm. The nanometer powder is wrapped by the silica gel fabric layer and the glass fiber fabric layer, therefore leakage of the nanometer powder can be prevented, and further, the silica gel fabric layer and the glass fiber fabric layer can be well attached to the surface of a valve, the valve is ensured to have identical heat insulation effect with pipelines, and on the premise of same heat insulation thickness, heat insulation effect can be improved by 1 / 2 to 1 / 3.
Description
technical field [0001] The invention relates to a thermal insulation material, in particular to a nano thermal insulation sleeve used for valve thermal insulation, and belongs to the technical field of thermal insulation materials. Background technique [0002] At present, people's awareness of energy saving in various production and life is constantly improving, and thermal insulation coating materials are widely used in various industrial pipelines, kilns, buildings, etc. Existing commonly used thermal insulation materials such as asbestos, glass fiber felt, aluminum silicate wool or glass fiber cloth, etc., in order to improve the thermal insulation effect, the method of increasing the thickness of the material is mostly used, but when this method is used, the thickness of the material itself increases. When it needs to be coated on the pipe, it will affect the coating effect and the number of layers of coating. Especially for the insulation of valves, due to the complex...
