Electric control pneumatic valve leakage of five solutions

Electric regulating pneumatic valve, when used in case of leakage phenomenon, should we how to deal with, here to introduce electric regulating pneumatic valve leakage of five solutions:


electric regulating pneumatic valve leakage of five solutions of lens gasket sealing method is used to


for the lid of the upper and lower sealing, pneumatic and upper and lower pneumatic valve seating. If plane sealing, under high temperature and high pressure, the sealing is poor, cause leakage, can adjust the lens gasket seal pneumatic valve to switch to electric, can get satisfactory results.


electric regulating pneumatic valve leakage change flow direction of five solutions


buy P2 on the pneumatic valve rod end method; When the delta P is bigger, P1 and large, seal P1 obviously difficult than seal P2. Therefore, electric regulating pneumatic valve to change flow direction method, P1 to P2 on the pneumatic valve rod end in pneumatic valve rod end, the high pressure, differential pressure pneumatic valve is more effective. Such as corrugated pipe pneumatic valve is usually sealed P2 should be considered.


electric regulating pneumatic valve leakage increase packing method of five solutions

is usually in the form of the double layer or multilayer mix packing is simply to increase the number of sealing gasket, such as between 3 to 5 pieces, to increase the sealing performance of pneumatic valve rod, but electric regulating pneumatic valve leakage effect is not obvious.



electric control pneumatic valve leakage of five solutions increase sealing grease method


this method is in view of the pneumatic valve body has not been used sealing grease, can consider to increase the sealing grease to improve the sealing performance of pneumatic valve stem. Daily maintenance of electric regulating pneumatic valve at ordinary times, increase the supplementary sealing grease is also one of the necessary maintenance program.


electric regulating pneumatic valve leakage of five of the solution is to replace graphite packing method


a large number of used ptfe packing, its working temperature in - shall apply 20 ~ 200 ℃ range, when the work for the larger changes in the upper limit and lower limit temperature, electric regulating pneumatic valve sealing performance was significantly lower, and the aging fast, short service life. Here it is recommended to use flexible graphite packing can overcome difficulties cannot bear by ptfe packing, and long service life, so as to improve the reliability of sealing. There are a lot of factories have all four fluorine filling to graphite packing, even the regulation of new purchase pneumatic valve will be one of the four fluorine used after packing into graphite packing. Graphite packing also has a drawback, however, is the return difference is big, the early some still produce the crawling phenomenon, to this, the producers and use when designing electric control pneumatic valve equipment installed to consider something also.


more about electric regulating pneumatic valve leakage of five solutions, hope for electric regulating pneumatic valve producers and users friends when dealing with the electric regulating pneumatic valve leakage, can help.
