Description

Sealing gasket

Technical Field

The utility model belongs to the technical field of it is sealed, concretely relates to sealed pad.

Background

When the existing pipeline is connected, a flange is mostly arranged on the end face of the pipeline and passes through the flange; the connection thus butt-joins the two pipes. The sealing performance needs to be ensured when the butt joint is carried out. The common sealing element with the structure is mostly a rubber flat gasket and is sealed through the extrusion deformation of the ring body. The sealing performance is poor, and the use requirement cannot be met.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a sealed pad, overcome the above-mentioned not enough of prior art, its sealing performance is strong, can keep long-time sealed effect, has satisfied market user demand, is favorable to the product to be promoted.

In order to achieve the above design purpose, the utility model discloses a technical scheme as follows:

the utility model provides a sealing gasket, includes the body, the axle center of body is equipped with the hole, the hole both ends are equipped with the joint bulge loop that outwards extends of symmetry setting respectively, the stainless steel ring is inlayed to the hole inner wall, and the joint bulge loop inner wall of both sides is extended respectively to stainless steel ring both ends.

The outer wall of the clamping convex ring is of an inclined structure.

The hole middle part is equipped with the recess, and stainless steel ring adopts interference fit's mode joint in stainless steel ring.

The groove is characterized in that the two ends of the groove extend to the inner walls of the clamping convex rings on the two sides, the position of the groove extending to the inner walls of the clamping convex rings is of an inclined structure, and the inclined structure is opposite to the inclined structure.

The diameter of the inner wall of the clamping convex ring is the same as that of the inner hole.

The body is provided with a fixing hole close to the edge.

The beneficial effects of sealed pad be: the sealing performance is strong, the long-time sealing effect can be kept, the market using requirements are met, and the product popularization is facilitated.

Detailed Description

The following is a more detailed description of the preferred embodiments of the present invention.

As shown in fig. 1-2, in the embodiment of the present invention, the sealing gasket, including body 1, the axle center of body 1 is equipped with hole 2, hole 2 both ends are equipped with the joint bulge loop 3 of the outside extension that the symmetry set up respectively, hole 2 inner walls are inlayed and are fixed stainless steel ring 4, and stainless steel ring 4 both ends extend to the joint bulge loop 3 inner wall of both sides respectively, strengthen the support performance of joint bulge loop 3, and during the use, joint bulge loop 33 adopts interference fit's mode to extend to in the pipe orifice of pipeline, has strengthened sealing performance through the cooperation of joint bulge loop with the pipe orifice.

The outer wall of the clamping convex ring 3 is of an inclined structure, so that the clamping convex ring can be conveniently extruded into a pipe hole of a pipeline.

The outer wall of the clamping convex ring 33 is of an inclined arc-shaped surface structure.

The middle part of the inner hole 2 is provided with a groove 5, and the stainless steel ring 4 is clamped in the stainless steel ring 4 in an interference fit manner.

The both ends of the groove 5 extend to the inner walls of the clamping convex rings 3 on the two sides, the position of the groove 5 extending to the inner walls of the clamping convex rings 3 is of an inclined structure, and the inclined structure is opposite to the inclined structure, and the inclined surface structures are arranged at the both ends of the stainless steel ring 4.

The diameter of the inner wall of the clamping convex ring 3 is the same as that of the inner hole 2.

The body 1 is provided with a fixing hole 6 near the edge for fixing the body 1.

The foregoing is a more detailed description of the invention, taken in conjunction with the specific preferred embodiments thereof, so that those skilled in the art can readily understand and apply the invention, and it is not intended to limit the invention to the specific embodiments described. To the ordinary technical personnel in the technical field that the utility model belongs to, can also make a plurality of simple deductions or replacement under the prerequisite that does not deviate from the utility model discloses the design, and needn't pass through creative work. Therefore, the simple modifications made by those skilled in the art according to the disclosure of the present invention should be within the scope of the present invention.
