Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flue compensators, in particular to a flue compensator. Background Technique
[0002] In industrial production, flue systems are widely used in various combustion equipment and industrial furnaces, etc. However, due to the influence of factors such as temperature changes, equipment vibrations, and internal pressure fluctuations during the operation of the flue, deformation and displacement are likely to occur. The traditional flue connection method usually adopts a rigid connection. When facing the deformation and displacement of the flue, this connection method is prone to problems such as stress concentration, seal failure, and even pipeline rupture. This will not only affect the normal operation of the flue system, but also may lead to safety hazards and environmental pollution. To solve these problems, flue compensators came into being. Flue compensators can absorb the thermal expansion and contraction, vibration, and displacement of the flue, ensuring the sealing and stability of the flue system, thereby improving the safety and reliability of the entire industrial production process.
[0003] However, for traditional equipment, when the compensator is connected and fixed to other equipment, it is only fixed and connected through a flange, and the sealing effect is relatively low. Poor sealing will cause the pressure inside the flue to be unstable, thereby affecting the performance of the equipment connected thereto. In some combustion equipment, the change of flue pressure will affect the combustion efficiency and heat transfer effect, reducing the production efficiency and product quality of the equipment, which needs to be improved.
