Pneumatic valve sealing capability is not strong is the key to do maintenance

As everybody knows, a pneumatic valve installation quality is good, the key lies in sealing. Even in the same company to buy, in use process will produce different sealing effect, the main reason lies in the daily maintenance work. How late say so, pneumatic valve used in sealing, mainly lies in the maintenance, small make up also not stingy, just share with you some maintenance tips. The first point, pneumatic valve on the amount of valve plate welding bolts can't be too long, if appear this kind of circumstance, because a long bolt causes the body to medium flow, causing sealing was 'built on stilts', the sealing function will fail. How to avoid this problem? Need not only good in the usual maintenance check bolt length, but also pay attention to check the adjusting screw during assembly opening, ensure that fit closely between the sealing surface. The second point, right pneumatic valve adjusting pad, as to how much is it should adjust the thickness of cushion, small make up a range for everyone, that is slightly less than or equal to the steps of the valve sealing surface height, has the standard, in order to make soft seal with the valve plate seal face fit closely, in the same plane. Third, to make sure that the nut off, be about to do a good job pressure, of course, after over tightening can make appropriate relax, need not too tight. Fourth, pneumatic valve when the choose and buy, should consider the use of fluid medium conditions, rather than to buy cheaper. After all, different models of pneumatic valve has a different medium, there will be no corrosion or high temperature deformation, and so on and so forth. Fifth, if the valve seat sealing surface damage is serious, don't need to repair, the seat directly to the disposal, but still can continue to use the improved valve core, and of course, with the same specification of the seat. Sixth, pneumatic valve is ready for work, remember to avoid fierce fierce close behavior, it is easy to shorten the service life of pneumatic valve gasket. In fact, it is not hard to see, small make up daily processing method is little things, everyone can focus on the, suggests that a good use and care for the pneumatic valve, if unable to focus on the use of follow one's inclinationsly, will affect the valve operation, the passage of time will shorten its service life, this is not everyone is happy.
