Abstract
The utility model discloses a kind of high vacuum shape metallic leak-proof structure, including connector, the first connector, the second connector and sealing ring.Beneficial effect is：1. being sealed using lead-antimony alloy, energy Baking out reaches the requirement of vacuum bakeout to 200 DEG C；2. lead-antimony alloy is used, with existing metal o-ring（Gold, silver and bronze aluminium）Compare, it is more soft, less sealing force is only needed it is ensured that the vacuum sealing that can be examined；3. because lead-antimony alloy is relatively soft, energy fully gluing, sealing face after deformation is compressed, it is not necessary to which high accuracy coordinates and very bright and clean sealing surface, difficulty of processing are low；It 4. because lead-antimony alloy is relatively soft, can arbitrarily bend, the step for no curling, shaping, reduce procedure of processing；5. the market price of lead-antimony alloy is with the 1/5 of model copper band, silver-colored 1/10, golden 1/100, and processes and compare that existing sealing metal is simple with welding, so the sealing of completion once same specification, cost substantially reduce, there is very big economic benefit.
Description
Technical field
It the utility model is related to metal hermetic seal device field, and in particular to a kind of high vacuum shape metallic leak-proof structure.
Background technology
1. existing metal o-ring elasticity is poor, it is necessary to which very big sealing force just can guarantee that reliable vacuum sealing；2. weight
Multiple usability is very poor, is often used only once；3. the roughness and fit precision of flange sealing surface and the edge of a knife require higher, very
Small cut can destroy sealing, and particularly large scale flange processing is highly difficult；4. the thermal expansion system of sealing ring and valve blue material
Number difference is larger, heats uneven or design of Sealing Structure and obtains incorrect, can cause local deformation and cause gas leakage.
The content of the invention
The purpose of this utility model is that to solve the above problems and provides a kind of high vacuum shape metallic leak-proof structure, with
Solve the problems of the prior art.
The utility model provides following technical scheme：
A kind of high vacuum shape metallic leak-proof structure provided by the utility model, including connector, the first connector, the second connection
Body and sealing ring；
First connector and the second connector are fastened together by the connector, and first connection
Annular seal space is formed between body and second connector；
The sealing ring is arranged in the annular seal space, and for sealing, and the material of the sealing ring is that lead-antimony alloy is close
Seal.
Preferably, second connector is provided with positioning table, the positioning table is used to position first connector.
Preferably, the connector is bolt.
Preferably, the bolt is hexagon socket head cap screw.
It the advantage is that：
1. being sealed using lead-antimony alloy, energy Baking out reaches the requirement of vacuum bakeout to 200 DEG C；
2. lead-antimony alloy is used, with existing metal o-ring（Gold, silver and bronze aluminium）Compare, it is more soft, only need less sealing
Power is it is ensured that the vacuum sealing that can be examined；
3. because lead-antimony alloy is relatively soft, energy fully gluing, sealing face after deforming is compressed, it is not necessary to which high accuracy coordinates and ten
Clean sealing surface is divided, difficulty of processing is low；
It 4. because lead-antimony alloy is relatively soft, can arbitrarily bend, the step for no curling, shaping, reduce procedure of processing；
5. the market price of lead-antimony alloy is with the 1/5 of model copper band, silver-colored 1/10, golden 1/100, and processes and weld
Connect simple compared to existing sealing metal, so completing the sealing of once same specification, cost substantially reduces, and has very big economic effect
Benefit.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of high vacuum shape metallic leak-proof structure described in the utility model.
Description of reference numerals is as follows：
1st, connector；2nd, the first connector；3rd, the second connector；4th, annular seal space；5th, sealing ring.
Embodiment
, below will be to technology of the present utility model to make the purpose of this utility model, technical scheme and advantage clearer
Scheme is described in detail.Obviously, described embodiment is only the utility model part of the embodiment, rather than all
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not before creative work is made
Resulting all other embodiment is put, belongs to the scope that the utility model is protected.
Shown in Figure 1, the utility model provides a kind of high vacuum shape metallic leak-proof structure, including connector 1, first connects
Junctor 2, the second connector 3 and sealing ring 5；
The connector 3 of first connector 2 and second is fastened together by the connector 1, and described first
Annular seal space 4 is formed between connector 2 and second connector 3；
The sealing ring 5 is arranged in the annular seal space 4, and for sealing, and the material of the sealing ring 5 is lead-antimony alloy
Sealing ring 5.
Preferably, second connector 1 is provided with positioning table, the positioning table is used to position first connector
1。
Preferably, the connector 1 is bolt.
Preferably, the bolt is hexagon socket head cap screw.
Its manufacturing process is as follows：
A. fuse material is lead-antimony alloy on the market, so commercially available certain length（Depend primarily on sealing surface size）
And line footpath（Depend primarily on reserved compression stroke）Specification；
B. lead-antimony alloy must be used using the welding gun welding cyclization higher than 400 DEG C, welding material, weld there mustn't be gas
Body remains；
C. it is the fine polishing of weld is smooth, it is not allow for raised and burr.
2. sealing surface requires
Because lead-antimony alloy is soft, therefore sealing surface does not have to the processing edge of a knife, and sealing surface need to only be processed to the high convex surfaces of 0.1 ~ 1mm
, crowning is used to extrude lead-antimony alloy sealing ring 5, roughness requirements Rc0.8 ~ 1.6,.
For fixed seal ring 5, while matching trim, need to and groove raised in 2 sealing surface locating and machinings coordinate, it is high
Degree depends on the circumstances.
It the advantage is that：
1. being sealed using lead-antimony alloy, energy Baking out reaches the requirement of vacuum bakeout to 200 DEG C；
2. lead-antimony alloy is used, with existing metal o-ring 5（Gold, silver and bronze aluminium）Compare, it is more soft, only need less close
Power is sealed it is ensured that the vacuum sealing that can be examined；
3. because lead-antimony alloy is relatively soft, energy fully gluing, sealing face after deforming is compressed, it is not necessary to which high accuracy coordinates and ten
Clean sealing surface is divided, difficulty of processing is low；
It 4. because lead-antimony alloy is relatively soft, can arbitrarily bend, the step for no curling, shaping, reduce procedure of processing；
5. the market price of lead-antimony alloy is with the 1/5 of model copper band, silver-colored 1/10, golden 1/100, and processes and weld
Connect simple compared to existing sealing metal, so completing the sealing of once same specification, cost substantially reduces, and has very big economic effect
Benefit.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
