Valve insulation clothing

Good insulation is an important aspect of energy conservation in every steam systemValve insulation clothingIn steam systems, valve insulation can effectively reduce heat loss and energy consumption. The commonly used manual valve in steam systems is a bellows sealed globe valve, which has a heat dissipation area equivalent to three times the area of the same diameter pipeline. A DN50 Watt DBF200 bellows sealed globe valve can dissipate 7200 kilograms of steam per year at a saturated steam pressure of 10 barg.

Taking the steam cost of 250 yuan/ton as an example, the heat loss alone reaches 1800 yuan/year Due to the relatively complex appearance of the valve itself and the need for frequent operation and regular maintenance, it is often seen on site that the steam pipeline has good insulation, but the steam valve does not have insulation. Insulation can reduce the heat dissipation of steam pipelines and valves, save energy, and insulation is required for any steam pipeline, valve, flange, joint, or container. Steam pipeline insulation reduces steam condensation caused by heat dissipation and avoids erosion, vibration, and water hammer effects on steam pipelines, valves, and heat exchangers caused by condensed water moving at high speeds with steam.

If the steam pipeline is not insulated, the steam flow rate must be reduced to transport the same quality of steam, requiring a larger steam pipeline. If electronic components (actuators, positioners, solenoid valves, etc.) are installed on the valve, insulation is beneficial for the stable operation of the electronic components. If the cylinders, valves, and pipelines in the boiler room are not insulated, the ambient temperature in the boiler room may even exceed 60 ℃. Steam valves that often require manual contact or operation must be insulated and avoided. Or to avoid valve closure issues caused by concerns.
