Negative pressure wave detection method is the use of sensors based on both ends of the leak point pressure drop and the negative pressure wave generated instant liquid leaked to the time difference in propagation downstream of the Gas Cooker valve leak detection to achieve the goal line. Advantage of negative pressure wave detection method lies in its high accuracy, small construction volume, low cost, easy to install and maintain.
In summary, in the petrochemical production valve leak this major accident hazards can not be ignored questions about corporate benefits, safety and environment has important implications. Therefore, the valve failure timely and accurate disclosure of the petrochemical industry found safe and efficient production is essential. Currently, the valve line detection technology has matured, but because it can effectively distinguish the case of gas cookers for sale leakage, for valves provide predictive maintenance tools, so in the near future with the outstanding advantages of acoustic emission and negative pressure wave line valve leak detection technology will be widely used.
