How to implement protective security pneumatic valve - Check the pneumatic - valve Hydrophobic pneumatic valve of steam

. Pneumatic valve safety protection facilities
in general, security before and after not set partition pneumatic valve, pneumatic valve only in individual cases, the safety set partition before and after pneumatic valve pneumatic valve. Such as medium to solid impurities, affect the safety of pneumatic valve cannot be locked after takeoff, in pneumatic valve should be installed in front of a safety belt brake pneumatic valve seal. Should be in full open position, brake pneumatic valve and safety valve installed between a check pneumatic valve size atmosphere of DN.
for security pneumatic valve discharge of wax, phenol and other medium at room temperature for the solid state, or decompression evaporation and make the medium temperature is lower than degrees such as lightweight liquid hydrocarbon, safe pneumatic valve need to steam heating.
for the safety of the corrosive medium pneumatic valve, depending on the pneumatic valve is corrosion resisting performance considerations in pneumatic valve inlet and corrosion resistance of the explosion-proof membrane.
gas safety pneumatic valve according to the general size set a by-pass pneumatic valve, as the manual vent.
　　. Check the pneumatic valve protection facilities
in order to prevent check pneumatic valve is leaking or failure after medium flow back, check the pneumatic valve should be set up before and after one or two to cut off the pneumatic valve. If set two cut pneumatic valve, can facilitate maintenance check pneumatic valve is removed.
　　. Pneumatic valve steam traps protective facilities
steam hydrophobic pneumatic valve with by-pass pipe and without by-pass pipe; Have the condensate recovery and recycling condensation points. Large displacement, and other special requirements of pneumatic valve, steam trap can be used in the form of parallel installation facilities.
