Structures
The damper butterfly valve is made of the same material as the valve body to form a sealing ring. Its operating temperature depends on the valve body material. The nominal pressure is <0.6MPa. It is generally suitable for industrial, metallurgical, environmental protection and other pipelines for ventilation and regulating medium flow. Its main features are:
Novel and reasonable design, unique structure, light weight, fast opening and closing.
2. Small operating torque, easy operation, labor-saving and dexterous.
3. Adopting suitable materials to meet low, medium and high medium temperatures and corrosive media.
Installation Precautions
The installation position and layout of the damper valve in the pipe network also affect the use of the valve. For pipes with large smoke and dust, a closed funnel is designed at the valve opening end or the valve connection corner. Regular dust removal can prevent excessive dust accumulation to facilitate the rotation of the valve plate. Several issues should be noted when installing the damper valve
1. When using metal gaskets, the load must be uniform to avoid the influence of temperature and deadweight or the stress generated by welding to bring additional pressure to the valve, causing the valve flange and pipeline to deform.
2. When the valve is installed in a place with a long pipeline, a support frame should be installed.
3. When installing the valve, pay attention to the flow direction of the medium so that the opening direction of the butterfly plate is consistent with the flow direction of the pipeline medium, which is conducive to the self-cleaning effect of the medium flow rate.
4. Strengthen the protection of the overall insulation layer of the pipeline network so that the pipe wall temperature is above the dew point, which can reduce the accumulation of low-temperature adhesive dust. If the pipe wall temperature is higher than the acid dew point of the flue gas, it can avoid condensation of acid vapor on the heated pipe wall and control the generation rate of sulfur trioxide, and the valve will be more effective. The installation position of the damper valve varies with the design of the pipeline, such as horizontal, vertical and corner. Generally, the damper valve installed on the vertical pipe has a better effect and is not easy to accumulate dust, followed by the horizontal pipe, and the effect at the corner is the worst. The turning points on both sides of the valve inlet and outlet are most likely to form bias flow and dust blockage, and the valve operating torque will increase.
