Forged steel cryogenic pneumatic - valve is given in detail - Its unique irreplaceable characteristics

a pneumatic valves, forged steel cryogenic parts contained material:
pneumatic valve, pneumatic valve seat, disc, pneumatic valve, pneumatic valve cover cover gasket, bolt, pneumatic stem and packing, cylindrical pin, eyelet bolt, packing pressure, packing pressure plate, nut, pneumatic valve stem nut, lubrication gasket, lock nut, the handwheel.


2 and the structure characteristics of pneumatic valves, forged steel, low temperature:
sealing gasket bolt connection coil and threaded all-welded sealed, full size or reducing, seal with a steady pressure hole ( Used for brake pneumatic valve, pneumatic ball valve) , integral seal seat, stem scaffolding, anti-static, self-centering clamp pressure shell summary for more than a few big characteristics.


3 pneumatic valves, forged steel, low temperature design of six requirements:
, pneumatic valve should be in the medium at low temperature and ambient temperature should have the ability to work long hours.
, in order to be kept in - Use ℃ low temperature, the pneumatic valves are designed to be extended type pneumatic valve cover.
, work under low temperature of the pneumatic valve assembly does not lubrication, so you need to take structure measures, in order to prevent the friction abrasion.
and low temperature medium should not produce harmful to the hand wheel operation and packing seal performance.
and direct contact with the low temperature medium pneumatic valve assembly should have explosion and fire prevention structure.
and pneumatic valves should not be a low temperature system of a significant source of heat. This is because the heat flow in addition to the lower thermal efficiency, such as flow too much, still can make internal fluid evaporation rapidly, produce abnormal booster, dangerous.


concluded:
forged steel cryogenic pneumatic valve is very suitable for thermal power plant all kinds of the pipeline system, the control line medium on and off. Applicable medium: water, steam and other corrosive medium. Pneumatic valve forged steel compared with other pneumatic valve products is characterized by high temperature and high pressure, special since the seal design, the higher the pressure, the more reliable seal. Because of performance technology characteristics, operating mode of the special products have formed the characteristics do not replace the other products.
