In many factories and consumer workshops, the overhaul and maintenance of equipment has begged to be standardized and institutionalized,pneumatic butterfly valveOf course, it is only an ordinary valve equipment, but in order not to affect the use and prolong the service life, it is necessary to take necessary maintenance measures on a daily basis. So, what are the maintenance methods?
Of course, regular maintenance will not be carried out every day. However, in order to ensure that the pneumatic butterfly valve can satisfy the application requirements and not be caught off guard by sudden shutdown, it is necessary to arrange regular personnel for inspection if daily maintenance cannot be carried out. Pneumatic butterfly valve timing maintenance content includes the working condition of the valve can be normal, applied to control the disposal of chemical medium fluid valve to check the corrosion condition.
Whether there is noise during operation, whether the sealing performance of the valve is good, whether there is fluid leakage when the valve is closed, etc., the pneumatic butterfly valve applied to the hydropower plant should also check whether the valve switch is blocked, and if there is blockage, it should be liquidated in time, otherwise it will greatly affect the application of the pneumatic butterfly valve.
The internal leakage of the valve generally refers to the situation that when the valve is completely closed, there is still medium flowing out of the valve's flow path outlet, leakage or dripping, etc. To put it more simply, it is not tightly closed and the seal is not good! The cause of the failure, usually because of the media erosion wear, or contain impurities and other reasons. Even if the valve screw (valve stem) is tightened in place, because there is still a gap between the valve core and the valve body, the medium can still flow through.
It is inevitable to maintain and repair defects in mechanical equipment. In addition to intermittent cleaning of pneumatic butterfly valves at regular intervals, it is also necessary to ensure whether the sealing performance of the valves is good or not, and to check the performance of pneumatic butterfly valves at regular intervals. If conditions permit, it is good to test intermittent equipment and instruments of pneumatic butterfly valves. In case of defects, it is also very important to find maintenance personnel to repair and convert damaged parts in time. Predictive maintenance work before other defects is also very important.
