As a device that opens and closes the valve by compressing gas, the pneumatic air valve greatly improves the performance of the valve. It is more and more widely used in industrial applications. The amount of use is large and the consumption is fast.
Therefore, in the process of using pneumatic air valves, we should pay attention to the daily maintenance and maintenance of pneumatic air valves. Have you done all the following daily maintenance and maintenance?
Maintenance work of pneumatic air valve
Before using the pneumatic air valve, wash the debris in the valve body with clean water.
Valve seals should be cleaned regularly to prevent leakage and wear.
When the pneumatic air valve is closed, if there is a lot of residual medium in the valve body, cut off the power supply and air source, and release all the pressure for cleaning.
Fully close and fully open the pneumatic air valve several times to verify whether the valve can work normally, check all details, and ensure that the valve is intact.
Tighten the flange nuts and bolts of the pneumatic air valve to prevent the flange connection problem caused by uneven force.
Daily maintenance of pneumatic air valves
When cleaning the valve, we should pay attention that the general medium can be cleaned with water, but if it is a special medium, the corresponding cleaning method should be selected instead of simple flushing.
In the process of disassembling the valve, we must first do the rust removal work on the rusted parts on the surface before disassembling. Use professional tools to remove the base.
The maintenance and replacement of parts and components are handled differently for different parts. For example, the two sealing surfaces of the valve core and valve seat are relatively small rust spots or wear, which can be repaired by mechanical processing. If it is serious, then It needs to be replaced with a new one; if the valve stem is damaged, it can only be replaced with a new one.
We should pay attention to the alignment in the process of assembling the pneumatic air valve, tighten the bolts on the diagonal, and add lubricating oil to the place where lubricating oil should be added. Remember to use the manufacturer’s method for testing and debugging after assembly to ensure that the closing position of the valve core is the same as that of the valve positioner.
