Specific implementation mode
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Referring to shown in Fig. 1-5, a kind of heat pipe air-tightness detection device, including lower clamp 2 and upper clamp 1, the lower clamp
The locating slot 3 of the S-shaped shape consistent with the shape of heat pipe to be detected with being formed on the opposing clamping surfaces of upper clamp, the positioning
Slot includes straight line portion and heel, the straight line portion close to the flexible sealing ring 6 in the position of heel, by straight line portion with it is curved
Head 7 separates, and after the upper clamp will be located into the clamping of the heat pipe in locating slot with lower clamp, each heel can be made to form one
A independent sealing space, in the installation of the outside of each corresponding heel, there are one air pressures on the side wall of the lower clamp
Table 5 is connected and is connected to by interface channel 4 between the barometric air inlet pipe and the independent sealing space.
Wherein, one end of the interface channel 4 extend out to outboard end from the side wall of the lower clamp, and is formed on the outside
The air gauge 5 is installed in threaded portion to facilitate.
Wherein, the lower clamp is fixed on bottom plate 9, and the top of the upper clamp can connect lifting drive rod 8,
Such as hydraulic-driven bar.In this way in use, lower clamp is fixed on bottom plate, upper clamp by lifting drive rod drive lifting carry out with
Lower clamp clamps heat pipe or takes out the work of heat pipe.
Wherein, the lower clamp and upper clamp are convex structure.In addition, after clamping in order to improve upper lower clamp
The sealing in clamping face can be fixed above locating slot certain altitude such as 2- in outside locating slot 3 respectively on the clamping face of upper and lower clamp
The elastic packing rubber layer (not shown) of 3mm, wherein the butt end of elastic seal ring 6 setting up and down respectively with corresponding bullet
The butt end of property sealing rubber layer mutually maintains an equal level, and in this way when upper lower clamp clamps, passes through the mutual of the elastic packing rubber interlayer
It squeezes, to form sealing structure, prevents gas from being had the gap between the clamping face of upper lower clamp and escape.
When work, heat pipe 100 is placed in the locating slot of lower clamp, then, upper clamp is pressed on lower clamp, and presses
Tightly, being present at the corresponding position of upper lower clamp due to flexible sealing ring, corresponding up and down after the clamping of upper lower clamp
Elastic seal ring docking compresses, the clamping face sealing of upper lower clamp, to separate the straight line portion of heat pipe with heel, to make
The section of locating slot where heel forms the space of an independent sealing, in this way, working as 130 envelope of the heat pipe other end
It closes, after one end 120 of heat pipe is passed through the nitrogen of detection, if having leakage at the weld seam 110 of the straight line portion of heel, leads to
Cross the situation of change that corresponding air gauge can detect air pressure, the case where so as to judge weld seam how.
The utility model passes through above technical scheme so that each heel is formed after upper lower clamp clamps heat pipe 100
One independent sealing space, in this way by the air gauge of connection or pressure test device, by the air pressure for detecting sealing space
Variation, you can it is easy to operate and simple in structure with the presence or absence of leakage between the weld seam 110 to judge each heel and straight line portion,
It is easy to use.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
