Pneumatic switch butterfly valve installation and maintenance considerations
The use of new products, especially the issue of the use of pneumatic butterfly valves that people are concerned about is also one that requires special attention. Any product has installation and maintenance considerations. Especially when using this product, the most important thing to care about is that the consumer is concerned with installation and maintenance. In addition, the precautions during installation and maintenance are also minor issues that cause people to doubt. Special precautions must be taken when installing and repairing. For those of you who don't understand this, we can learn to understand together.
The installation and maintenance of good performance pneumatic butterfly valves are also not to be underestimated. Therefore, pneumatic butterfly valves also have their own installation and maintenance. At the same time, people are also very concerned about the issue. Then, what are the precautions for their installation and maintenance?
First, pay attention to the butterfly valve pipe. Before installation and use, we must pay attention to the process of a strong flushing of the pipe. This process is carried out with the valve fully opened. The purpose of this is mainly to prevent scratches on the sealing surface, such as welding slag and other debris, affecting the sealing performance.
Second, we must pay attention to the direction of circulation, to a great extent, we must prevent the use of problems in the process, so when installing the butterfly valve, we should pay close attention to the unique flow direction signs on the valve body to prevent the flow of the wrong direction. For better use in the future.
Third, pay attention to repair or replace the butterfly valve, because the bypass valve is generally set inside the butterfly valve, especially during the inspection, must be carried out in accordance with the use of bypass piping.
Fourth, in the horizontal range, the pneumatic butterfly valve can be installed vertically but remember that it must not flip its pneumatic actuator down.
Fifth, in the pneumatic actuator, its crank arm is a square-headed structure and can even be used with a manual device. However, if a manual operation is required during a fault, then it is necessary to directly remove the gas source pipe during the process. Use a manual wrench on it.
Sixth, once the stuffing box is found to be infiltrated during use, this can only be solved by tightening the gland bolts.
Through the understanding of the matters concerning the installation and maintenance of pneumatic butterfly valves, we can use it well in the future.
