工业生产中的阀门保温工作越来越得到企业的重视。无保温的高温阀门在运行过程中会被环境温度冷却，其温度低于阀门内表面温度，容易产生温差和热应力。特别是蒸汽管道中的阀门，有效的保温措施可以减少蒸汽冷凝，避免冷凝水对阀门形成的冲蚀、振动和水锤等影响。
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.
柔性可拆卸阀门保温罩选择耐高低温、防火原材料制作，由内衬、中间保温层、外部保护层三层结构组成。可以有效减少热损失，提高经济效益，改善热环境。与传统的保温方式相比，有其独特的优势。
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.传统保温只能使用一次；柔性可拆卸保温套可重复使用。
1. Traditional insulation can only be used once; The flexible removable insulation jacket can be reused.
2.传统保温方式不适合在异形复杂的设备上安装；而可拆卸保温罩适用于不同形状的管道和设备，尤其是异形件更具优势。
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.传统保温方式的外表是铝或铁，不耐腐蚀；柔性可拆卸阀保温套可以添加耐酸碱的四氟涂层材料，其环境适应性更强，比传统保温更具优势。
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.传统保温不能在小空间内使用；柔性可拆卸阀门保温套广泛应用于小空间。
4. Traditional thermal insulation cannot be used in a small space; Flexible removable valve insulation jacket is widely used in small space.
5.传统保温方式保温材料多为岩棉硅酸铝等，保温效果一般；可拆卸保温方式多采用导热系数更低的保温材料，用很薄的结构就可以起到比传统保温方式更好的保温效果。
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.
