Chamber is engaged, and when the gland is by the axial force for pointing to the supporting plate, the elastic metallic seal is pressed on described
On the inwall of cavity.
Preferably, the taper α of the inner chamber of the elastic metallic seal is 21 ° -25 °.
Preferably, the taper theta of the gland is bigger than the taper α of the inner chamber of the elastic metallic seal 0.45 ° -0.55 °.
Preferably, hardness number≤150HBW of the elastic metallic seal.
Preferably, roughness Ra≤0.8 μm of the elastic metallic seal.
Preferably, in addition to studs, the supporting plate are connected by the studs with the gland.
Sealed it can be seen from the above technical proposal that being provided with elastic metallic in removable seal structure of the present utility model
Part, the inner chamber of the elastic metallic seal is taper, and gland is also taper.Gland is engaged with elastic metallic seal.Wait to press
When lid is by the axial force for pointing to supporting plate direction, elastic metallic seal is pressed on the inwall of cavity by gland, and axle
Xiang Liyue is big, and gland is bigger to the thrust of elastic metallic seal.Further, since the material of elastic metallic seal is gold
Category, compared to non-metallic seals such as soft graphites, elastic metallic seal is unlikely to deform, so as to influence relevant device
Stroke, it is ensured that relevant device is accurately run.
Brief description of the drawings
In order to illustrate more clearly of the scheme in the utility model embodiment, will make below to required described in embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the utility model,
For those skilled in the art, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings
Accompanying drawing.
Fig. 1 is the schematic diagram that Light deformation occurs for the elastic metallic seal that the specific embodiment of the utility model one provides；
Fig. 2 is the schematic diagram for the removable seal structure that the specific embodiment of the utility model one provides.
Wherein, 1 it is elastic metallic seal, 2 be gland, 3 be supporting plate, 4 be studs, 5 is inwall.
Embodiment
The utility model provides a kind of removable seal structure, and the removable seal structure has excellent sealing
Can, and do not interfere with the stroke of relevant device.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than all
Embodiment.Based on embodiment of the present utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained all other embodiment, belong to the scope of the utility model protection.
Fig. 1-Fig. 2 is refer to, in the specific embodiment of the utility model one, removable seal structure includes：Supporting plate 3,
Gland 2 and elastic metallic seal 1
Wherein, supporting plate 3 is connected with cavity, for supporting gland 2.Gland 2 is within the cavity, for preventing medium flow field
It is logical.Supporting plate 3 is to be detachably connected with gland 2.Especially, the elastic metallic seal 1 in the present embodiment is taper.Gland 2
Also it is taper.The gland 2 of taper is inserted into the interior intracavitary into taper.When gland 2 is by the power for pointing to supporting plate 3, gland 2
With the trend moved to supporting plate 3, then after the part being relatively large in diameter on gland 2 enters the inner chamber of elastic metallic seal 1,
The inwall 5 of elastic metallic seal 1 can be extruded, makes elastic metallic seal 1 that radial direction Light deformation, elastic metallic seal 1 occur
It is filled between gland 2 and inwall, forms good sealing.During use, before medium is passed through, first by gland
2 are connected in supporting plate 3, make axial pre tightening force of the gland 2 by sensing supporting plate 3, so as to compress elastic metallic seal 1,
Elastic metallic seal 1 is formed tightening seal, be passed through medium afterwards, for gland 2 by the axial compression power of medium, gland 2 enters one
Step ground compresses elastic metallic seal 1, and medium is bigger to the extruding force of gland 2, extruding of the gland 2 to elastic metallic seal 1
Power F1 is also bigger, and the elastic metallic seal 1 in the present embodiment has adaptivity.
Further, since the material of elastic metallic seal 1 is metal, compared to the non-metallic seals such as soft graphite, bullet
Property metal seal 1 be unlikely to deform, so as to which the stroke of the grade relevant device of gland 2 would not be influenceed, it is ensured that the grade relevant device of gland 2
Accurately run.
In the specific embodiment of the utility model one, by the taper α of the inner chamber of elastic metallic seal 1 be preferably 21 °-
25 ° of degree.Elastic metallic seal 1 in the range of taper can obtain preferable radial direction Light deformation, preferably close so as to obtain
Seal effect.
The inner chamber of elastic metallic seal 1 is inserted in order to facilitate gland 2, while gland 2 squeezes to inner chamber generation for convenience
Pressure, in the specific embodiment of the utility model one, taper theta 0.45 degree of -0.55 degree bigger than the taper α of inner chamber of gland 2.
In the specific embodiment of the utility model one, will be above-mentioned in elastic metallic seal 1 hardness number be preferably≤
150HBW.Elastic metallic seal 1 in the hardness range value by gland 2 extruding when expected deformation can occur
Amount, sealing effectiveness expected from acquisition.To elastic metallic seal 1 carry out austenite material sofening treatment after can obtain it is above-mentioned in
Hardness number.
In order to ensure gland 2 can swimmingly extrude elastic metallic seal 1, in the specific embodiment of the utility model one
In, the roughness by elastic metallic seal 1 is preferably Ra≤0.8 μm.Can be by Digit Control Machine Tool to elastic metallic seal 1
Carry out Precision Machining, the roughness value during acquisition is above-mentioned.
