Thermal insulation of butterfly valves is an indispensable protective measure to save energy, improve the thermal efficiency of equipment, ensure product quality, and ensure normal operation of equipment. It includes valve thermal insulation, cold insulation, heating protection and other forms.
All pipes and equipment maintained at a certain temperature or temperature range through insulation materials and heating measures are collectively called insulation, including insulation measures aimed at reducing heat loss and energy consumption;
Measures aimed at preventing condensation on the outer surface of the pipeline or the inner surface of the pipeline, that is, insulation measures for the purpose of reducing or maintaining the temperature of the working environment, improving working conditions, and preventing fires caused by surface overheating or burns to operators. cooling measures.
Thermal insulation of pipeline transportation projects includes: insulation for stable heat dissipation conditions during normal operation and heat tracing insulation for unstable heat dissipation conditions after shutdown.
Butterfly Valve insulation range:
1. During the production operation, if the temperature of the medium needs to be kept stable, it should be kept warm or insulated.
2. In order to reduce the loss of heat or freezing capacity, heat preservation or cold preservation is required.
3. In order to prevent the medium temperature from freezing or crystallizing when the temperature drops below the freezing point or crystallization point, it should be insulated, and based on the freezing point or crystallization point, determine whether to use steam for heat tracing.
4. If the gas medium produces liquid due to solidification and corrodes the valve, it should be insulated.
5. The water-containing liquefied gas will self-cool and freeze due to pressure drop, so it should be insulated and heated.
6. If the medium evaporates due to the influence of external temperature, it should be kept cold.
7. The process conditions do not require heat preservation, but in order to improve the operating environment and prevent burns, heat preservation should also be done.
