Summary of the invention
The present invention aims to provide a kind of safe aerating device that uses, and to solve inflatable inflation nut, exists and splits and to the make children problem of body injury of operating personnel.
The invention provides a kind of aerating device, comprise the gas-charging connection for inflatable inflation nut is inflated, aerating device also comprises that protective sleeve is connected coaxially with gas-charging connection for be set in the protective sleeve outside the inflation nut when inflating.
Further, protective sleeve and gas-charging connection removably connect.
Further, protective sleeve and gas-charging connection are spirally connected.
Further, protective sleeve and inflation nut clearance fit.
Further, aerating device also comprises and prevents from inflating the movable cutting ferrule that nut is deviate from protective sleeve.
Further, movable cutting ferrule is arranged on protective sleeve rotationally, and the active card cover has the primary importance of chucking inflation nut, and the second place of unclamping the inflation nut.
When further, movable cutting ferrule is included in primary importance with the clamp of inflation nut end butt and the web joint that is connected to the clamp two ends; Web joint is rotatably connected away from the end of clamp and the stationary shaft on protective sleeve.
Further, be provided with O shape circle between the hold-down nut of web joint and stationary shaft end.
Further, be provided with arc groove on clamp, arc groove matches to be connected to the end of inflating nut with the connecting pipe of inflation nut one end.
Further, the material of protective sleeve is for can bear the metal material that compression shock is greater than 15MPa.
Further, the material of movable cutting ferrule is for can bear the metal material that compression shock is greater than 15MPa.
According to aerating device of the present invention, protective sleeve is set on gas-charging connection, protective sleeve is cylindric the inflation nut is formed and surrounds, thereby stops inflating when nut splits the fragment formation flown out, and effectively prevents the debris damage staff.

Fig. 5 is the connecting board structure schematic diagram according to the movable cutting ferrule of aerating device of the present invention.
Embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
As depicted in figs. 1 and 2; according to aerating device of the present invention; comprise the gas-charging connection 20 for inflatable inflation nut is inflated, aerating device also comprises that protective sleeve 20 is connected coaxially with gas-charging connection 10 for be set in the protective sleeve 20 outside the inflation nut when inflating.Protective sleeve 20 is cylindric the inflation nut is formed and surrounds, thereby stops inflating when nut splits the fragment formation flown out, and effectively prevents the debris damage staff.
Preferably, protective sleeve 20 adopts and removably connects with gas-charging connection 10, as threaded engagement, is convenient to quick-replaceable different size protective sleeve 20, meets the production requirement of different size heat interchanger, improves the versatility of equipment.
Preferably, protective sleeve 20 and inflation nut clearance fit, and gap is less, thus guarantee to inflate the concentricity that nut and protective sleeve 20 cooperatively interact, reduced because misoperation causes type inflatable has been inflated to the hidden danger of quality that nut fractures.
As illustrated in fig. 1 and 2; aerating device also comprises movable cutting ferrule 30, and type inflatable on air-condition heat exchanger inflation nut inserts protective sleeve 20 and while dock with gas-charging connection 10, it is spacing that 30 pairs of movable cutting ferrules are inflated nuts; prevent from inflating nut and deviate from protective sleeve 20, thereby improve protection effect.
Preferably, as shown in Figure 5, on clamp 31, be provided with inflate nut on the arc groove 31a that coordinates of pipe, improve the contact area of clamp 31 and inflation nut, thereby make movable cutting ferrule 30 tighten better the inflation nut, the raising reliability.
According to the pressure requirement in the process of air-condition heat exchanger high pressure leak detection, design the compression shock that whole aerating device can bear and be greater than 15MPa, protective sleeve 20 and movable cutting ferrule 30 all adopt and can bear the metal material that compression shock is greater than 15MPa and be made.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect:
According to aerating device of the present invention, will inflate nut fully and be enclosed in protective sleeve inside, and use activity cutting ferrule chucking to be fixing, while preventing from inflating the nut explosion, fragment flies out and gases at high pressure are gone out device the potential safety hazard of hurting sb.'s feelings, and effectively guarantees product safety production.Aerating device of the present invention, be convenient to assembling and take out, and do not affect the operating efficiency of high-pressure aerated, high pressure pressurize and high pressure leak detection, and reduced and type inflatable has been inflated to the hidden danger of quality that nut fractures because of misoperation.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
