The valve insulation work in industrial production has been paid more and more attention by enterprises. The high-temperature valve without insulation will be cooled by the ambient temperature during operation, and its temperature is lower than the internal surface temperature of the valve, which is easy to generate temperature difference and thermal stress. Especially for the valves in the steam pipeline, effective thermal insulation measures can reduce steam condensation and avoid the impact of condensed water on the erosion, vibration and water hammer of the valves.

柔性可拆卸閥門保溫罩選擇耐高低溫、防火原材料制作，由內襯、中間保溫層、外部保護層三層結構組成。可以有效減少熱損失，提高經濟效益，改善熱環境。與傳統的保溫方式相比，有其獨特的優勢。

The flexible removable valve insulation cover is made of high and low temperature resistant and fire-resistant raw materials, and is composed of three-layer structure: lining, intermediate insulation layer and external protection layer. It can effectively reduce heat loss, improve economic efficiency and improve thermal environment. Compared with the traditional insulation method, it has its unique advantages.

1.傳統保溫只能使用一次；柔性可拆卸保溫套可重復使用。

1. Traditional insulation can only be used once; The flexible removable insulation jacket can be reused.

2.傳統保溫方式不適合在異形復雜的設備上安裝；而可拆卸保溫罩適用于不同形狀的管道和設備，尤其是異形件更具優勢。

2. The traditional thermal insulation method is not suitable for installation on special-shaped and complex equipment; The detachable insulation cover is suitable for pipes and equipment of different shapes, especially for special-shaped parts.

3.傳統保溫方式的外表是鋁或鐵，不耐腐蝕；柔性可拆卸閥保溫套可以添加耐酸堿的四氟涂層材料，其環境適應性更強，比傳統保溫更具優勢。

3. The appearance of traditional thermal insulation is aluminum or iron, which is not corrosion resistant; The flexible detachable valve insulation sleeve can be added with acid-base resistant PTFE coating material, which has stronger environmental adaptability and more advantages than traditional insulation.

4.傳統保溫不能在小空間內使用；柔性可拆卸閥門保溫套廣泛應用于小空間。

4. Traditional thermal insulation cannot be used in a small space; Flexible removable valve insulation jacket is widely used in small space.

5.傳統保溫方式保溫材料多為巖棉硅酸鋁等，保溫效果一般；可拆卸保溫方式多采用導熱系數更低的保溫材料，用很薄的結構就可以起到比傳統保溫方式更好的保溫效果。

5. The traditional thermal insulation materials are mostly rock wool and aluminum silicate, with general thermal insulation effect; The detachable thermal insulation method mostly uses thermal insulation materials with lower thermal conductivity, and the very thin structure can play a better thermal insulation effect than the traditional thermal insulation method.
