Pneumatic valve, pneumatic cryogenic deadline 196 ℃ image

Air temperature as pneumatic valve is a dedicated to harsh working conditions of low temperature pneumatic valve, in - usually work on temperature 196 ℃ of liquid ammonia, liquefied natural gas, liquid nitrogen, such as ethylene, propylene, cryogenic medium relatively interesting pneumatic valve, pneumatic valve packing parts are generally higher design, pneumatic valve stem also USES the extension rod, and to prevent cryogenic deformation, main parts after cryogenic treatment, which can guarantee the pneumatic valve in ultra-low temperature conditions remain flexible switch.








pneumatic ultra-low temperature by the pneumatic valve, pneumatic valve and high temperature need to consider many factors, one of the main materials and packing seal, according to the different temperature levels, pneumatic valve stem and valve GaiYan long size is different also, pneumatic valve usually choose CF8, LCB, LF1, F304 material, such as pneumatic, pneumatic valve seat sealing surface welding carbide, improve the scour resistant ability of pneumatic valves, prolong the service life of pneumatic valve, widely used in cryogenic liquid handling equipment management system management system, can also be used for no other particles as on-off or adjust the use of a cryogenic liquid.









pneumatic ultra-low temperature by the pneumatic valve lengthen the height of the pneumatic valve cover, make sure that the packing standard must be low temperature position of the temperature not too low, if take ordinary room temperature pneumatic valve used in low temperature condition doesn't work, a packing position high enough, the packing is easy to leak, the second is not after cryogenic treatment, pneumatic valve body material is not suitable for low temperature, three pneumatic valve material is not resistant to low temperature.
