The sealing connection structure comprises the stainless steel pipe and a soft metal plate connected with the stainless steel pipe. A through hole is formed in the soft metal plate, a through hole type sealing head is arranged at the end of the stainless steel pipe, the outer surface of the end portion of the sealing head is of a drum-shaped structure, a flange is arranged on one side of the drum-shaped structure, and the sealing face side of the flange is recessed. The sealing structure is low in machining accurate requirement, high in connection strength and simple in operation mode, does not require other auxiliary materials, and meanwhile ensures good sealing performance between metals under the high temperature environment.
Description
Technical field
The utility model relates to nuclear radiation detection technical field, is specifically related to the Hermetical connecting structure of a kind of Stainless Steel Tube and dissimilar metal plate.
Background technique
In nuclear radiation detector structure, in order to obtain good energy response, or prevent neutron activation metal, tend to adopt aluminum alloy material; And the belted type cable shell being connected with prober is stainless steel, so just relate to the problem that is connected and guarantees sealing of Stainless Steel Tube and aluminium alloy plate.
Because physics, chemistry and the mechanical property aspect of stainless steel and aluminum alloy exists huge difference, conventional fusion welding method cannot weld.At present, the common Hermetical connecting structure of Stainless Steel Tube and aluminium alloy plate has two kinds: a kind of is screw connection structure, and a kind of is braze-welded structure.The sealing effect of screw connection structure and poor reliability, joint geometry is complicated, and the requirement on machining accuracy of double thread is high.Braze-welded structure need to be selected applicable braze and welding method, as vacuum brazing method, high-frequency induction brazing method etc.; Need on the one hand special-purpose soldering oven, in brazing process, need high-temperature heating on the other hand, thereby make to change through the aluminum alloy organization of strengthening, strength decreased; And braze can be softened in the Environmental Conditions of high temperature, it is unreliable to seal.
Model utility content
The purpose of this utility model is exactly in order to overcome above-mentioned technical problem, and provide the Hermetical connecting structure of a kind of Stainless Steel Tube and dissimilar metal plate, this structure requirement on machining accuracy is low, join strength is high, mode of operation is easy, do not need other auxiliary material, guarantee that under hot environment, intermetallic sealability is good simultaneously.
The technological scheme that the utility model solves its technical problem employing is: the Hermetical connecting structure of a kind of Stainless Steel Tube and dissimilar metal plate, comprise Stainless Steel Tube and connected soft metal sheet, described soft metal sheet is provided with through hole, described Stainless Steel Tube pipe end is provided with a through hole type sealing head, the end outer surface of described sealing head is drum organization, drum organization one side is provided with flange plate, and the sealing surface of flange plate is spill.
In such scheme, the concave panel of described flange plate and the outer surface of described drum organization are tangent.
In such scheme, the sealing surface that described Stainless Steel Tube sealing head and soft metal sheet form is labyrinth sealing face.
In such scheme, described soft metal sheet is aluminum alloy or Cuprum alloy, under the extruding of Stainless Steel Tube sealing head, can deform, with Stainless Steel Tube interlock to one.
In such scheme, Stainless Steel Tube sealing head is pressed into soft metal sheet by hydraulic press or press machine.
The Hermetical connecting structure of a kind of Stainless Steel Tube of the utility model and dissimilar metal plate, this structure requirement on machining accuracy is low, and join strength is high, and mode of operation is easy, does not need other auxiliary material, guarantees that under hot environment, intermetallic sealability is good simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the Hermetical connecting structure of the utility model Stainless Steel Tube and dissimilar metal plate.
Fig. 2 is the machining sketch chart of the Hermetical connecting structure of the utility model Stainless Steel Tube and dissimilar metal plate.
Wherein: 1. Stainless Steel Tube, 2. flange plate, 3. drum organization, 4. soft metal sheet, 5. Stainless Steel Tube sealing head.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, the present embodiment provides the Hermetical connecting structure of a kind of Stainless Steel Tube and dissimilar metal plate, comprise Stainless Steel Tube and connected soft metal sheet, described Stainless Steel Tube 1 contains a sealing head 5, on sealing head 5, be processed with flange plate 2 and drum organization 3, before connecting, the lower end surface diameter of drum organization 3 is less than soft metal sheet 4 through-hole diameters, being convenient to sealing head 5 is connected with through hole accurately, the maximum cross-section diameter of drum organization 3 is greater than soft metal sheet 4 through-hole diameters, can effectively seal guaranteeing after sealing head 5 is pressed into soft metal sheet 4.By hydraulic press or press machine, by sealing head 5 process of press in, the through hole of soft metal sheet 4 deforms,, to one, closely connect between the two with sealing head 5 interlocks, and the sealing surface of its formation is tortuous, and be labyrinth sealing face.Above-mentioned soft metal sheet 4 can adopt aluminum alloy or Cuprum alloy.
Structure of the present utility model can adopt existing processing method to realize, and describes a kind of processing technology of dissimilar metal Hermetical connecting structure below in conjunction with accompanying drawing 2:
(1) at a sealing head 5 of the end of Stainless Steel Tube 1 processing, sealing head 5 has the through hole communicating with steel pipe, processes spill flange plate 2 and drum organization 3 on sealing head 5;
(2) on soft metal sheet 4, process a through hole;
(3) use hydraulic pressure installation or press machine, sealing head 5 is pressed in the through hole of soft metal sheet 4, the through hole of soft metal sheet 4 deforms, with sealing head 5 interlocks to one, the sealing surface forming is between the two labyrinth sealing face, thereby realize Stainless Steel Tube, is firmly connected and seals with soft metal sheet.
Claims (4)
1. the Hermetical connecting structure of a Stainless Steel Tube and dissimilar metal plate, comprise Stainless Steel Tube and connected soft metal sheet, it is characterized in that: described soft metal sheet is provided with through hole, described Stainless Steel Tube pipe end is provided with a through hole type sealing head, the end of described sealing head is drum organization, drum organization one side is provided with flange plate, and the sealing surface of flange plate is spill.
