Abstract
A sexangular bolt end surface sealing device comprises a sexangular bolt and a seal ring, wherein a groove is formed in a flange, the groove is ring-shaped, and a seal ring is arranged inside the groove. After the adoption of the structure, the sexangular bolt end surface sealing device provided by the utility model has the advantages that the structure is simple, the processing and the use are convenient, and no mounting clearance is left.
Description
Technical field
The utility model relates to seal arrangement, especially relates to a kind of hex head bolt face seals.
Background technique
Hex head bolt uses very general, the bolt seal face is had in the occasion of requirement at some, the general employing is coated with sealer, and perhaps the method at workpiece processing seal groove realizes, but these methods are in the occasion that cleanings such as pharmacy or food are had relatively high expectations, sealer is generally inadvisable, at workpiece processing seal groove and then the method for O type circle is set, owing to have the gap between the hex surface of bolt and workpiece, then there is contamination of heavy in the gap, therefore, this method is also improper.
Summary of the invention
The purpose of this utility model provides a kind of hex head bolt face seals, and it is simple in structure, pollution-free, can be widely used in clean zone.
The problem of the required solution of the utility model realizes by the following technical solutions: the hex head bolt face seals, comprise: hex head bolt, seal ring, it is characterized in that: flange is provided with groove, and described groove is annular shape, is provided with seal ring in the groove.
The utility model adopts above-mentioned structure, and is simple in structure, and processing and use are all very convenient, do not have assemblage gap.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the C part enlarged view among Fig. 1.
Among the figure: 1, hex head bolt, 2, flange, 3, seal ring.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
The hex head bolt face seals comprises hex head bolt 1, seal ring 3, and it is characterized in that: flange 2 is provided with groove, and described groove is annular shape, is provided with seal ring 3 in the groove.When the utility model uses, seal ring 3 is placed in flange 2 grooves, the hex head bolt 1 that screws up with a wrench then gets final product, and can effectively fill up the opening of groove after seal ring 3 is extruded.The hex head bolt of this device is simple in structure, need not process seal groove at all the other workpiece, installs between back bolt and workpiece very close to each other.
Obviously; above-described embodiment of the present utility model only is for the utility model example clearly is described; but be not used for limiting scope of the present utility model; all technological schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by every claim.
