Abstract

A metal sealing ring gasket comprises an annular metal body, wherein the upper end face of the body is a plane, the lower end face of the body is an inwards concave conical surface, and grooves are formed in the upper end face and the lower end face of the body to form an easily deformable structure. The utility model discloses a rational in infrastructure, place when using in the face is connected to equipment, only need not big pretightning force, can produce the pressurized deformation, make the upper and lower terminal surface of ring pad body can fully contact sealedly, even the pretightning force of equipment junction distributes inhomogeneous also can the natural deformation adaptation, ensure that sealed cooperation is good, avoid the seepage, improved the hard sealed whole reliability of metal ring pad greatly.

Description

Metal sealing ring gasket

The technical field is as follows: the utility model relates to a hard sealing ring, especially metal ring pad that field such as industrial container, pipeline used.

Background art: the upper end face of the existing partial metal sealing ring gasket is a plane, the lower end face of the existing partial metal sealing ring gasket is a concave conical surface, and the existing partial metal sealing ring gasket is placed in an equipment connecting face and needs to be pre-tightened and pressurized through fasteners such as bolts and the like, so that the contact part can be in sealing fit. However, the pretightening force required by some hard seals is large, the pretightening force distribution at the connection part of the equipment is likely to be uneven, the insufficient sealing contact and the uneven tightness are easy to occur, the sealing fit is not good, the leakage is generated, and the sealing reliability is reduced.

The invention content is as follows: the utility model provides a metal seal ring gasket with reasonable structure and reliable sealing, which is not enough for the prior art.

The utility model discloses an annular metal body, the up end of body is the plane, the lower terminal surface is the conical surface of indent, all is equipped with the recess on the upper and lower terminal surface of body, forms yielding structure.

The utility model discloses a rational in infrastructure, place when using in the face is connected to equipment, only need not big pretightning force, can produce the pressurized deformation, make the upper and lower terminal surface of ring pad body can fully contact sealedly, even the pretightning force of equipment junction distributes inhomogeneous also can the natural deformation adaptation, ensure that sealed cooperation is good, avoid the seepage, improved the hard sealed whole reliability of metal ring pad greatly.

The invention is further described with reference to the following figures and examples.

Description of the drawings: fig. 1 is a schematic diagram of the main structure of the embodiment.

Fig. 2 is a top view of fig. 1.

The specific implementation mode is as follows: as shown in fig. 1 and 2, the upper end surface of the annular metal body 1 is a plane, the lower end surface is a concave conical surface, and the upper end surface and the lower end surface of the body 1 are both provided with grooves 2, so as to form an easily deformable structure. In this embodiment, the grooves 2 formed in the upper end surface of the body 1 are trapezoidal grooves, and the number of the grooves 2 formed in the lower end surface of the body 1 is two. Therefore, when the sealing ring is pressed to deform, the upper end surface and the lower end surface can be in full contact with corresponding positions better, and the sealing is more reliable.

This embodiment also all is equipped with recess 2 on the inside and outside periphery lateral wall of body 1, has further improved the deformability, and contact deformation adaptability is better.
