Description
Technical field
The utility model belongs to detection technique field, and in particular to a kind of pack boronitriding Portable low-pressure is airtight
Property detection device.
Background technique
Pack boronitriding forms simple, compact-sized and to produce gas rapid as a kind of gas supply device with it
Feature is widely used in all kinds of different occasions.In gas generator development, production and test preparation process, in order to anti-
Seal failure caused by only occurring because of reasons such as neglected loadings, pack boronitriding need to carry out low pressure air-leakage test.
For pack boronitriding, for the Small Solid gas generator applied under especially some high altitude environments,
Its air-leakage test has the particular/special requirement of itself；Firstly, detection pressure is low, absolute pressure is generally required to be less than 0.15MPa；Its
Secondary, detection pressure required precision is high, and deviation is required to must not exceed 0.01MPa；Again, gas generator internal cavities are small.
Due to these features, some traditional large-scale air-tightness detection devices are not often suitable for small gas generator
Air-leakage test is easy to the problem of detecting pressure superelevation occur in the detection process.In addition, for large-scale air-tightness detection device
Adaptability reform need higher cost.Therefore, it is necessary to the air-leakage test requirement for small gas generator, design inspections
Survey low pressure, the high and low cost of precision and portable air-tightness detection device.
Utility model content
In view of the above problems, the object of the present invention is to provide a kind of Portable low-pressure air-tightness detection devices, can
Low pressure air-leakage test is carried out to Small Solid gas generator.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of pack boronitriding Portable low-pressure air-tightness detection device, low pressure air-tightness detection device, which has, to be used
To provide the inflator of low inflation for pack boronitriding；The end for the loading line connecting with the inflator is equipped with
To realize the small tyre valve cock of one-way air inlet；Side at the top of the pack boronitriding is provided with detection switching
Head；The detection adapter is three-port structure, and the detection adapter upper right side import is connect with small tyre valve cock,
The detection adapter left upper end import and the low pressure to be detected to the pressure inside pack boronitriding
The lower end outlet of table connection, the detection adapter is connected with the internal cavities of the pack boronitriding.
The utility model proposes a kind of pack boronitriding Portable low-pressure air-tightness detection device, using inflating
Cylinder is that the pack boronitriding is inflated, and realizes the slow boosting in other small gas generator, ensure that interior
Portion's pressure accurately meets air-leakage test requirement；Relative to conventional air tightness detection equipment, the present apparatus has small in size, structure
Simply, feature at low cost, time is short, easy to carry；The utility model can complete small gas under no gas source condition
The low pressure air-leakage test of generator is suitble to use in the simple and crude place of guarantee condition.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, pack boronitriding, 2, detection adapter, 3, pressure gauge, 4, small tyre valve cock, 5, gas tube
Road, 6, inflator.
Specific embodiment
The utility model is illustrated with reference to the drawings and specific embodiments:
As shown in Figure 1, a kind of pack boronitriding Portable low-pressure air-tightness detection device, low pressure air-leakage test
Device has to provide the inflator 6 of low inflation for pack boronitriding 1；The gas tube being connect with the inflator 6
The end on road 5 is equipped with the small tyre valve cock 4 to realize one-way air inlet；The one of 1 top of pack boronitriding
Side is provided with detection adapter 2；The detection adapter 2 be three-port structure, the 2 upper right side import of detection adapter with
Small tyre valve cock 4 connects, the 2 left upper end import of detection adapter and to inside to pack boronitriding 1
The low pressure gauge 3 that pressure is detected connects, the lower end outlet of the detection adapter 2 and the pack boronitriding
1 internal cavities are connected.
In above-described embodiment, the pack boronitriding 1 and small tyre valve cock 4 are mature in the prior art
Structure, don't explain too much here.
The low pressure air-tightness detection process of pack boronitriding 1 is as follows: firstly, finishing device and pack boronitriding
1 connection；Later, pressure inflator 6 is taken out repeatedly, is slowly inflated into pack boronitriding 1；In gas replenishment process, low pressure is observed
Pressure gauge 3 disconnects the connection of loading line 5 and small tyre valve cock 4 when pressure reaches air-leakage test required value；It is small
Type tyre valve 4 can realize the sealing of pack boronitriding 1 after one-way air inlet and end inflation in gas replenishment process；Most
Afterwards, within the time that air-leakage test requires, low pressure gauge 3, and the variation of recording manometer pressure values is observed, is judged whether
It meets the requirements.In addition, in the case where 1 internal pressure of pack boronitriding is higher than required value, it can be by squeezing small tyre
The valve inside of valve cock 4, portion gas of releasing make internal pressure meet air-leakage test requirement.
