In addition, in technical scheme described in the utility model, it is all not do what is illustrated, it can use normal in this area
Rule means realize the technical program.
The utility model has advantages below：It is close that the utility model is placed into sound insulation when coming into operation, by pressure vessel
In joint sealing, and by compressed air charged pressure container, due to muffler, the sound-absorbing material of admission line inwall and itself
Ascending internal diameter change serves well reduces or even prevents the effect for inflating noise, and the presence of sound insulating seal case makes
Quiet enough around pressure vessel, secondly, sound pick-up is directly adsorbed on pressure vessel by magnetite, by the good sound of solid
Sound propagating characteristic, pressure vessel gas leakage sound is more accurately caught, makes testing result more accurate, and can be with usual when
Sound pick-up is conveniently taken down, does not influence pressure vessel normal work.Be additionally provided with pipeline of the present utility model pressure sensor and
Stop valve, after closing stop valve, pressure sensor is still connected with pressure vessel, can pass through pressure sensor detection pressure
Pressure value in container, and in sound insulating seal case set compressed gas (such as few hydrogen of content etc. in air) gas
Concentration sensors, whether can also be sent out from side monitoring pressure container by the monitoring of pressure sensor, gas concentration sensor
Raw leakage.The advantages that the utility model has that testing result is accurate, easy to use and flexible, and compact cost is low, easy to spread.
