Abstract
The invention discloses an end-to-end connection seal part. The seal part comprises a retainer ring and seal bodies, wherein the retainer ring and the seal bodies are made of metal materials. Containing grooves for containing the seal bodies are formed in the upper and lower ends of the retainer ring, and the seal bodies are arranged inside the containing grooves. In the process of sealing the end faces of two mechanical parts through the seal part, it is only needed to make the end faces of the two mechanical parts abut against the end face of the retainer ring, and therefore it is avoided that the seal part is broken through pressing.
Description
Technical field
The present invention relates to a kind of end-to-end link Sealing.
Background technique
For end-to-end link mechanical part, in order to ensure that two mechanical parts connect between its end face and have good sealability, need to arrange Sealing between both ends of the surface, general Sealing is O type circle.
Generally realize being interconnected by forms such as bolts between two mechanical parts, this Placement cannot predict the pressure size of two mechanical parts to Sealing, if two mechanical parts connect too tight, then easily cause its end face pressure break O type circle, thus affect sealing effect; If two mechanical parts connected pine, then easily caused O type circle not fit tightly the both ends of the surface of mechanical part, and also can affect sealing effect.Therefore be necessary to improve existing Sealing.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of end-to-end link Sealing.
The present invention is achieved through the following technical solutions: a kind of end-to-end link Sealing, comprises back-up ring and the seal of metal material, all arranges the receiving groove holding described seal, in described receiving groove, arrange described seal at the upper and lower two ends of described back-up ring.
In technique scheme, described receiving groove has the sidewall of circular arc.
The present invention has following beneficial effect: in the process sealed two mechanical part end faces by Sealing of the present invention, two mechanical part end faces lean and stop to during described back-up ring end face, therefore can not produce the situation of damaging Sealing by pressure.
Accompanying drawing explanation
Fig. 1 is schematic top plan view of the present invention.
Fig. 2 is cross-sectional schematic of the present invention.
Fig. 3 is the cross-sectional schematic of another embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail, embodiment 1: see Fig. 1 to Fig. 2, a kind of end-to-end link Sealing, comprise back-up ring 1 and the seal 2 of metal material, the receiving groove 10 holding described seal 2 is all set at described back-up ring about 1 two ends, described seal 2 is set in described receiving groove 10.
In the process seal two mechanical part end faces, two mechanical part end faces lean and stop to during described back-up ring 1 end face, now cannot continue to press down two mechanical parts, therefore can not produce the situation of damaging seal 2 by pressure.
Embodiment 2: see Fig. 3, described receiving groove 10 has the sidewall of circular arc, embodiment 2 all the other with embodiment 1, when seal 2 stress deformation, there is the shape of fitting with the receiving groove 10 of circular arc sidewall, ensure that seal 2 can be fixed in described receiving groove 10 comparatively reliably.Embodiment 2 working principle, with embodiment 1, does not repeat them here.
Claims (2)
1. an end-to-end link Sealing, comprise back-up ring and the seal of metal material, it is characterized in that: described back-up ring upper and lower opening shape, centre arranges same material baffle plate and back-up ring is divided into upper and lower two ends, the receiving groove holding described seal is all set at the upper and lower two ends of described back-up ring, described seal is set in described receiving groove.
2. a kind of end-to-end link Sealing according to claim 1, is characterized in that: described receiving groove has the sidewall of circular arc.
