Pneumatic health type pneumatic valve use should pay attention to the point

the standard electronic polishing pneumatic health type pneumatic valve, to ensure smooth surface is clean, no medium stockpile area, won't produce potential pollution. Widely used in such as food, pharmaceutical, cosmetics and clean steam, alcohol, beverage, chemical industrial process control occasions. When use should pay attention to the use of pneumatic health type pneumatic valve method to guarantee the normal work of the pneumatic health type pneumatic valve.
pneumatic health type pneumatic valve in use should pay attention to the following points:
a pneumatic valves, pneumatic type health operators to clearly understand the role of each of the pneumatic valve and position in the process piping, avoid the wrong operation, otherwise may form run material, mixing, pressure-out and other accidents. As a refining installation, pneumatic health type pneumatic valves for steam purging at the starting line, leak off after an object completely dynamic purge valve, as a result, the construction, ℃ high temperature slurry from the object completely discharge valve, the formation of the fire, the introduction of installation.
2, pneumatic health type pneumatic valve packing gland shoulds not be too tight, sensitive to pneumatic valve lever to rotate the advisable, too tight, will increase the pneumatic valve rod friction, increase the operating torque, etc. Pneumatic valve work, general conditions can bring pressure to change or add packing, otherwise, will cause media reveal that provoked the risk.
3, low temperature below ℃ of season, to stop using the pneumatic valve, to pay more attention to prevent frostbite, promptly open the bottom of the pneumatic valve plug, the inside of the discharge frozen water. For not cleaning and continuous work of pneumatic valve to heat preservation measures.
4, pneumatic pneumatic valve for high temperature, when the temperature rises to ℃ above, heating the bolt elongation, easy to make the pneumatic valve seal is lax, demand response to bolt to stop the 'hot', hot tight, unfavorable in pneumatic valve seated position stop. In order to avoid pneumatic valve peak of death, and open.
pneumatic health type pneumatic valve leakage, should first ascertain the leak position and reason, two kinds of normal condition and the outer part leak leak, according to its external structure is divided into external leakage filler leakage and leakage of pneumatic valve cover, pneumatic valve body and leakage of sealing ring or lining materials, the operator should be very accurate, I can deal with to timely, cannot handle to repair timely
