Specific embodiment
With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this
The protection scope of utility model is not limited by the specific implementation.
Embodiment one
As shown in figures 1 and 3, a kind of pressure vessel leak detecting device provided by the embodiment of the utility model, comprising: empty
Air compressor 1, gas booster pump 2, multistage tracheae 3, gas pressure sensor 4, aspiration pump 5 and control system；

Embodiment two
As shown in Fig. 2, third end face mouthpiece is arranged on first end face mouthpiece, third end face mouthpiece and the
One end face mouthpiece is connected, and the first valve is located at the outside of third end face mouthpiece, is arranged in original intake pipe connection and takes out
Air pipe interface does not open up pumping interface tube, save the cost, automation control pumping and air inlet again, easy to use.
The two sides company of the multistage tracheae 3, first end face mouthpiece, second end face mouthpiece 6 and third end face mouthpiece
The place of connecing is to be tightly connected, and is tightly connected by interface thread plus rubber gasket.
It further include the hand-held ultrasound detection device and X-ray non-destructive testing device for being detected to weld, progress
Determine specific leak position.
Detection method and working principle: before detection, the gas in the detection pressure vessel 7 of gas pressure sensor 4 is first passed through
Body pressure, if the pressure of the natural gas in pressure vessel 7 is higher than the sets requirement of control host, control host passes through solenoid valve
Open aspiration pump 5 be evacuated, by tracheae 3 by remaining natural gas transmission into other pressure vessels.
After the pressure of gas in pressure vessel reaches the sets requirement of control host, control host is closed by solenoid valve
Aspiration pump 5, then closes suction interface by the valve at second end face mouthpiece, and control host passes sequentially through solenoid valve starting
Air compressor 1 and gas booster pump 2, air compressor 1 prepare compressed air, and gas booster pump 2 adds compressed air
Pressure, by multistage tracheae 3 be pressure vessel 7 in be filled with it is pressurized after compressed air, when the atmospheric pressure in pressure vessel reaches
To after the sets requirement of control host, control host closes gas booster pump 2 by solenoid valve, at first end face mouthpiece
Valve close intake interface, in the time range of setting, such as in 20~60 minutes, if there is gas leak, gas pressure
Force snesor 4 will test the pressure that gas pressure intensity is less than setting, and alarm pipes alarm, and otherwise, alarm is not rung, and illustrates to press
Force container 7 does not leak.
When there is gas leakage, the gas pressure intensity of detection and the gas pressure intensity of setting are checked when alarm pipes by display
Difference, may thereby determine that the size of leakage rate, for specific leak position, since leakage mostly occurs in connection defect
Place further tests weld by hand-held ultrasound detection device or progress X-ray non-destructive testing device, does not have to
Each pressure vessel detects weld using ultrasonic detection device or X-ray non-destructive testing, greatly improves pressure
The detection efficiency of force container.
