With reference to drawings and Examples, the utility model is further elaborated.It should be appreciated that specific implementation described herein
Example is only used to explain the utility model, is not used to limit the utility model.
Fig. 1 and Fig. 2 is referred to, leakage detection apparatus 100 in the utility model preferred embodiment, for the valve to gas cylinder 200
201 leak detections, the leakage detection apparatus 100 include the valve bonnet 101 of one end open, the detecting element 102 and the valve bonnet of detection gas
101 cavitys pass through the blowing device 105 for connecting of gassing pipe 104 and the leak detector 106 being connected with the detecting element 102.
Valve bonnet 101 is the cover of the bottom end opening of cylindrical shape, it would be desirable to which the valve 201 of gas cylinder 200 of leak detection is covered.For
So that cover is with the sealing property of gas cylinder 200 more preferably, one can be set at the opening of valve bonnet 101 can be with the valve 201 of gas cylinder 200
The sealing gasket of the laminating of surrounding.If so valve 201 has leakage, gas concentration will increase in valve bonnet 101.The present embodiment
In, to be inserted in valve bonnet 101 by gassing pipe 104 and be blown into air or other gases thereto, purpose has：One is to purge as early as possible
The detected gas that clean last time is remained in valve bonnet 101 when detecting, it is to avoid residual gas disturbs this to detect, improve detection essence
Degree；Two is that, when cover is pressed in and is sealed on gas cylinder 200, the gas being blown into makes to form malleation in cover, can make detected gas
Accelerate flow detection element 102, thus accelerate the speed of leak detection.In addition, detecting element 102 is gas sensor.
Wherein in one embodiment, with reference to Fig. 1, detecting element 102 is arranged in the cavity of the valve bonnet 101, detection
Element 102 is arranged at valve bonnet 101 and covers the valve 201 of gas cylinder 200 positioned near the position of valve 201, is easy to quick detection valve
Whether door 201 has gas to leak.Or, it is arranged in leak detector 106, you can to use the leak detector for carrying detecting element 102
106.If detecting gas has leakage, detecting element 102 will send corresponding signal to leak detector 106, and leak detector 106 will send
Alarm and reminding.
In a preferred embodiment, leakage detection apparatus 100 also include pumping equipment 107, the pumping equipment 107 and the valve bonnet
101 are connected by aspirating air pipe 108.With reference to Fig. 2, in the present embodiment, detecting element 102 is arranged at the cavity of the valve bonnet 101
It is interior, in the interface A that the aspirating air pipe 108 is connected with the valve bonnet 101.Or, it is arranged on the aspirating air pipe 108
Optional position B.Or, it is arranged at the interface C that the pumping equipment 107 connects with the pipe of the aspirating air pipe 108.That is, unit is detected
Part 102 can be arranged on the optional positions such as the two ends or centre of aspirating air pipe 108, it is also possible to using carrying detecting element 102
Leak detector 106；And leak detector 106 can also carry air blowing and/or air suction function, that is, carry air pump.
After the detected gas that last time remains in valve bonnet 101 when detecting are purged totally, by pumping equipment 107 to valve
Cover 101 is aspirated, and accelerates the air circulation in the cavity of valve bonnet 101, and detecting element 102 is arranged at aspirating air pipe 108
The optional position such as two ends or centre, the air of valve bonnet 101 can move quickly through detecting element 102, improve detection efficiency.
In the present embodiment, blowing device 105 and the pumping equipment 107 are two different equipment, respectively by blowing
Pipeline 104 and aspirating air pipe 108 are connected with valve bonnet 101.It is of course also possible to be inflatable mouth and the air entry difference of same equipment
Connected with valve bonnet 101 by gassing pipe 104 and aspirating air pipe 108.In addition, the interface that gassing pipe 104 is connected with valve bonnet 101
The interface connected with valve bonnet 101 with aspirating air pipe 108 can also be same interface.
And in other embodiments, blow and air-breathing be not while when carrying out, and generally, existing air blowing
Equipment 105 also has air suction function simultaneously.Based on this, it may be considered that blowing device 105 and the pumping equipment 107 can be same
One equipment, and gassing pipe 104 and aspirating air pipe 108 are same pipeline.So, it is possible to use one has also suction after air blowing
The equipment of airway dysfunction realizes the function of blowing device 105 and the pumping equipment 107 simultaneously.Only need to by a pipeline and valve
Cover 101 is connected, and when detection starts, first the cavity to valve bonnet 101 is blown, and carries out air-breathing again thereafter, so can be cost-effective
And the device space.
Pumping equipment 107 is the cylinder of the piston being engaged with cylinder body and with cylinder body, takes out blower pump, folding type telescopic
Epithelium, rubber balloon or vavuum pump.Blowing device 105 is the cylinder of cylinder body and the piston being engaged with cylinder body, takes out blower pump, folding
The scalable epithelium of stacked or rubber balloon.
Above-mentioned leakage detection apparatus 100 whether there is gas leakage by automatic detection gas cylinder 200, improve leak detection speed, Ci Zhongjian
Leakage device 100 can be used in and fill on production line, instead of traditional water inspection rotating disk, will dramatically saves on the sky of fueling station
Between, and this equipment can support the use with other equipment, it is not necessary to and operating personnel are equipped with, the cost of labor of enterprise is reduced.This
Outward, the residual gas in valve bonnet 101 is discharged by using blowing device 105, can accurately detects current measured gas cylinder 200
With the presence or absence of gas leakage, accuracy of detection is improve.Further, pumping equipment 107 is also set up, to the valve bonnet after discharge residual gas
101 are evacuated, and accelerate air circulation, improve detection speed.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
