Description

Metal winding gasket

Technical Field

The utility model relates to a gasket, the better metal winding gasket of sealed effect specifically says so.

Background

The metal wound gasket is a widely used sealing gasket, is a gasket with the best rebound resilience in a semi-metal sealing gasket, is formed by alternately winding a thin steel belt and various fillers, can resist high temperature and high pressure, and can be used under the conditions of ultralow temperature or vacuum.

At present, a conventional metal-wound gasket includes an annular gasket body, which includes less than two concentrically arranged metal rings, and a graphite ring is filled between two connected metal rings. The sections of the metal ring and the graphite ring are both in a V shape protruding outwards, and the sections of the metal ring and the graphite ring are matched in shape, so that the end face of the pad body is in a V shape. The outer side of the pad body is concentrically sleeved with a metal positioning ring. The inner ring surface of the metal positioning ring in the metal winding gasket is a plane, when the metal winding gasket is connected with the outer ring surface of the gasket body, only the outer ring surface of the gasket body corresponding to the v-shaped peak is in contact with the metal positioning ring, the contact part is in line contact, the contact area is small, and the connection reliability is poor.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a metal winding gasket, this metal winding gasket's area of contact is great, and the reliability of connection is better.

In order to solve the problems, the following technical scheme is provided:

the utility model discloses a metal winding gasket includes annular pad body, and this pad body contains the metal loop that is less than two concentric arrangements, and it has the graphite circle all to fill between two metal loops that link to each other. The sections of the metal ring and the graphite ring are both in a V shape protruding outwards, and the sections of the metal ring and the graphite ring are matched in shape, so that the end face of the pad body is in a V shape. The outer side of the pad body is concentrically sleeved with a metal positioning ring. The metal positioning ring is characterized in that an annular groove is formed in the inner ring surface of the metal positioning ring, the end surface of the annular groove is V-shaped, the outer ring surface of the section of the pad body corresponding to the v-shaped peak is abutted against the groove bottom of the annular groove, and the outer ring surfaces of the pad body on two sides of the v-shaped peak are abutted against two groove walls of the annular groove respectively.

The inner side of the pad body is concentrically fixed with a metal reinforcing ring, an annular bulge is arranged on the outer annular surface of the metal reinforcing ring, the end surface of the annular bulge is V-shaped, the section of the inner annular surface of the pad body corresponding to the V-shaped peak is abutted against the tip of the annular bulge, and the inner annular surfaces of the pad body on two sides of the V-shaped peak are respectively abutted against two side walls of the annular bulge.

By adopting the scheme, the method has the following advantages:

because the utility model discloses a have annular groove on the metal positioning ring's of metal winding gasket the interior anchor ring, annular groove's terminal surface is the v style of calligraphy, and that section that the v-arrangement summit corresponds fills up the outer anchor ring of body and offsets with annular groove's tank bottom, and the outer anchor ring of the pad body of v-arrangement summit both sides offsets with two cell walls of annular groove respectively. The metal positioning ring of the metal winding gasket is provided with the annular groove, and the side wall of the annular groove is connected with the outer annular surface of the gasket body, so that the connection between the gasket body and the metal positioning ring is changed into surface connection, the contact area is greatly increased, and the connection reliability is ensured.

fig. 2 is a schematic sectional view taken along line a-a of fig. 1.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the metal-wound gasket of the present invention includes an annular gasket body 1, the gasket body 1 includes less than two metal rings 101 concentrically arranged, and a graphite ring 102 is filled between two connected metal rings 101. The sections of the metal ring 101 and the graphite ring 102 are both in a v shape protruding outwards, and the sections of the metal ring 101 and the graphite ring 102 are matched in shape, so that the end surface of the pad body 1 is in a v shape. The outer side of the pad body 1 is concentrically sleeved with a metal positioning ring 2. An annular groove 4 is formed in the inner annular surface of the metal positioning ring 2, the end face of the annular groove 4 is V-shaped, the outer annular surface of the section of the pad body 1 corresponding to the v-shaped peak is abutted to the groove bottom of the annular groove 4, and the outer annular surfaces of the pad body 1 on two sides of the v-shaped peak are abutted to the two groove walls of the annular groove 4 respectively.

The inner side of the pad body 1 is concentrically fixed with a metal reinforcing ring 3, an annular bulge 5 is arranged on the outer annular surface of the metal reinforcing ring 3, the end surface of the annular bulge 5 is V-shaped, the inner annular surface of the pad body 1 corresponding to the V-shaped peak is abutted against the tip of the annular bulge 5, and the inner annular surfaces of the pad body 1 on two sides of the V-shaped peak are respectively abutted against two side walls of the annular bulge 5.

The metal positioning ring 2 of the metal winding gasket is provided with the annular groove 4, and the side wall of the annular groove 4 is connected with the outer annular surface of the gasket body 1, so that the connection between the gasket body 1 and the metal positioning ring 2 is changed into surface connection, the contact area is greatly increased, and the connection reliability is ensured.
