Abstract
The utility model relates to a kind of Bolt Connection Bidirectional static seal structure, comprises bolt, bullet pad, plain cushion, seal ring.There are chamfering or recessed seam in aperture place, plain cushion side, chamfering or recessed seam side fitting tight circle, and seal ring embeds in plain cushion chamfering or recessed seam; Abutting contact face, plain cushion embedded seal ring side is assembled.Seal ring embeds in plain cushion chamfering or recessed seam, and during bolt tightening, seal ring is extruded generation elastic strain, radially with axially blocks all gaps completely, prevents the generation of fluid leakage.
Description
Technical field
The utility model relates to technical field of engineering machinery, especially a kind of Bolt Connection Bidirectional static seal structure.
Background technique
Conventional sealing adopts the materials such as paper, rubber parts or soft metal part to realize axially or radial one-way sealing structural type, both made to increase seal ring between pad and sealing surface, the gap on surface of contact can be blocked to a certain extent, but still there is situation about axially revealing, be difficult to ensure axis and the complete hermetic effect of radial direction simultaneously.
Model utility content
Technical problem to be solved in the utility model is a kind of Bolt Connection Bidirectional static seal structure designed for above-mentioned problems of the prior art.There are chamfering or recessed seam in aperture place, plain cushion side, and embedding sealing circle, while tools for bolts ' pretension, realize sealing, and then solve the poorly sealed problem causing fluid leakage of surface of contact.
The utility model solves the technological scheme that its technical problem adopts:
A kind of Bolt Connection Bidirectional static seal structure, comprises bolt, bullet pad, plain cushion, seal ring.
There is chamfering at described aperture place, plain cushion side, chamfering side fitting tight circle.
Polished rod position and the surface of contact bolt through-hole matching gap of described bolt are little, make seal ring be extruded distortion in the confined space, fill required seal clearance.
Described seal ring embeds in plain cushion chamfering, and abutting contact face, plain cushion embedded seal ring side is assembled.
Described aperture place, plain cushion side also can be recessed seam form, and seal ring is assemblied in recessed seam.
The utility model has following beneficial effect:
Seal ring is embedded in plain cushion chamfering or recessed seam, and during bolt tightening, seal ring is extruded generation elastic strain, radially with axially blocks all gaps completely, prevents the generation of fluid leakage.
Accompanying drawing explanation
Fig. 1 is the utility model overall schematic.
1-bolt; 2-bullet pad; 3-plain cushion; 4-seal ring; 5-surface of contact.
Embodiment
The utility model is set forth further below in conjunction with accompanying drawing.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should understand, after the content of having read the utility model instruction, those skilled in the art can make various changes or modifications the utility model, and can be used for other mechanical bolts and connect sealing mechanism, these equivalent form of values fall within the application's appended claims limited range equally.
The utility model is a kind of Bolt Connection Bidirectional static seal structure, as shown in Figure 1, comprises bolt 1, bullet pad 2, plain cushion 3, seal ring 4.
Described seal ring 4 is O-ring seals or rectangular seal, and the polished rod diameter of its size and bolt 1 and the chamfering angle size of plain cushion 3 adapt; Seal ring 4 embeds the chamfering of plain cushion 3 or recessed seam; Abutting contact face, plain cushion 3 embedded seal ring 4 side 1 is assembled.
Assembly process: first load bullet pad 2 on bolt 1, reinstall plain cushion 3, outwards have chamfering or recessed seam side, then embedding sealing circle 4, is finally screwed into surface of contact 5 by the component assembled, as shown in Figure 1.
Seal ring 4 is extruded in plain cushion 3 chamfering or recessed seam, with surface of contact 5 together hold-down bolt aperture on the polished rod being tightly attached to bolt 1, make bolt hole radial be axially closed simultaneously, intercepted and fluidly revealed.
