And unclamp the second position of inflation nut.
Further, when movable cutting ferrule is included in primary importance with inflate clamp that nut end abuts and be connected to clamp two ends
Connecting plate；Connecting plate is rotatably connected with protecting the fixing axle put away from the end of clamp.
Further, it is provided with O between connecting plate and the fixing nut of fixing shaft end.
Further, clamp being provided with arc groove, arc groove matches to be connected to the connecting tube of inflation nut one end
The end of inflation nut.
Further, the material of protection set is the metal material that can bear compression shock more than 15MPa.
Further, the material of movable cutting ferrule is the metal material that can bear compression shock more than 15MPa.
According to the aerating device of the present invention, arranging protection set on gas-charging connection, protection set cylindrically forms bag to inflation nut
Enclose, thus the fragment flown out when splitting inflation nut is formed and stops, effectively prevents debris damage staff.

Detailed description of the invention
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As depicted in figs. 1 and 2, according to the aerating device of the present invention, including for inflatable inflation nut is inflated
Gas-charging connection 20, aerating device also includes, for the protection set 20 being set in when inflation outside inflation nut, protecting set 20 and filling
Gas joint 10 connects coaxially.Inflation nut is cylindrically formed and surrounds by protection set 20, thus flies when splitting inflation nut
The fragment gone out is formed and stops, effectively prevents debris damage staff.
Preferably, protection set 20 removably connects, such as threaded engagement with gas-charging connection 10 employing, it is simple to quick-replaceable difference is advised
Lattice protection set 20, meets the production requirement of different size heat exchanger, improves the versatility of equipment.
Preferably, protection set 20 and inflation nut matched in clearance, and gap is less, so that it is guaranteed that inflation nut and protection set 20
The concentricity cooperated, reduces to cause because of misoperation and type inflatable is inflated the hidden danger of quality that nut fractures.
As illustrated in fig. 1 and 2, aerating device also includes movable cutting ferrule 30, inflates nut when the type inflatable on air-conditioning heat exchanger and inserts
When entering protection set 20 and dock with gas-charging connection 10, movable cutting ferrule 30 is spacing to inflation nut, prevents from inflating nut abjection protection
Set 20, thus improve protection effect.
Movable cutting ferrule 30 is rotatably arranged on protection set 20, and movable cutting ferrule 30 has the primary importance of clamping inflation nut,
And unclamp the second position of inflation nut.It is easy to assembling and takes out, during use, only movable cutting ferrule need to be turned to primary importance,
Can easily be arranged on the type inflatable inflation nut needing protection.As Fig. 3 is to shown in 5, and movable cutting ferrule 30 is included in first
The clamp 31 abutted with inflation nut end during position and the connecting plate 32 being connected to clamp 31 two ends；Connecting plate 32 is away from card
The end of plate 31 is provided with axis hole 32a, axis hole 32a and rotatably coordinates with the fixing axle on protection set 20.When inflation nut inserts
After in protection set 20, rotation activity cutting ferrule 30 to primary importance, make clamp 31 abut with inflation nut end, thus prevent from filling
Gas nut abjection protection set 20.Preferably, as in figure 2 it is shown, set between connecting plate 32 and the fixing nut 21 of fixing shaft end
It is equipped with O 22, such that it is able to the degree of tightness making movable cutting ferrule 30 fixing is moderate, it is simple to movable cutting ferrule 30 can be at any angle
Location, can not will not position because of the most loose during rotation, also will not be inconvenient to rotate because of too tight.
Preferably, as it is shown in figure 5, be provided with on clamp 31 and inflate the arc groove 31a that pipe on nut coordinates, improve card
Plate 31 and the contact area of inflation nut, so that movable cutting ferrule 30 preferably clamping inflation nut, improve reliability.
Pressure requirements during hunting leak according to air-conditioning heat exchanger high-voltage, designs the compression shock that whole aerating device can bear
The metal material system that can bear compression shock more than 15MPa is all used more than 15MPa, i.e. protection set 20 and movable cutting ferrule 30
Form.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
According to the aerating device of the present invention, completely inflation nut is enclosed in protection set internal, and use activity cutting ferrule clamping is fixed,
When preventing inflating nut explosion, fragment flies out and device is gone out the potential safety hazard hurted sb.'s feelings by gases at high pressure, product safety is effectively ensured raw
Produce.The aerating device of the present invention, it is simple to assemble and take out, does not affect the operation effect of high-pressure aerated, high pressure pressurize and high pressure leak detection
Rate, and reduce because type inflatable is inflated the hidden danger of quality that nut fractures by misoperation.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for those skilled in the art
For, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made, etc.
