The gas radiation pneumatic valve risk analysis

to control the furnace top pressure, rising gas pipe at the top of the set of hydraulic drive gas divergent pneumatic valve. When the top gas pressure or greater. MPa, alarm and automatically opened one of the gas emission pressure pneumatic valve have diarrhoea, ensuring the safety of the gas pipeline system. The gas radiation pneumatic valve as safety device. The main danger and harmful factors are as follows:
( ） Poisoning
a. In the operating loss in the process of the pneumatic valve, replacement and maintenance, due to wrong operation may cause gas leakage, such as protective measures do not reach the designated position, poisoning accidents may occur.
b。 Tossing in pneumatic valve due to aging, corrosion and so on, may leak, once people near the area, may be poisoning accident.
( ） Fire and explosion
in the above all kinds of gas leakage cases, such as gas concentration reached the explosion limit range, and with Mars, fire, gas explosion may occur, and cause a fire.
( ）
noise in the process of purging pressure, there is a certain noise, such as improper protective measures, workers work in noise environment for a long time, can lead to workers' hearing loss.
( ） Falling
in the process of gas radiation pneumatic valve replacement, aerial work involved, may be falling accident.
