Description
Technical Field
The utility model belongs to the technical field of it is sealed, concretely relates to can bear wound gasket of internal and external pressure simultaneously.
Background
A common winding type gasket structure is shown in figure 1 and formed by winding V-shaped steel belts, flexible graphite and other non-metallic materials are filled between the steel belts, and the winding type gasket has good sealing performance.
The disadvantages of this structure: the V-wrap gasket facilitates sealing against media pressure from the direction of the V-opening (which may be referred to as "inner seal") and against sealing against media from the direction of the V-cusp (which may be referred to as "outer seal").
Disclosure of Invention
The purpose of this application is to provide a winding type gasket structure to overcome the defects of the prior art, which can simultaneously seal the media from the V-shaped opening and the V-shaped sharp point, i.e. can simultaneously bear the pressure of the inner and outer media.
The technical scheme of the application is as follows: the utility model provides a can bear wound form gasket of internal and external pressure simultaneously, wherein, includes the winding steel band in inboard and outside, sets up flexible material between adjacent steel band, the steel band is the V-arrangement setting, and divide into two parts, sets up the V-arrangement opening of the steel band in the inboard inwards, sets up the V-arrangement opening of the steel band in the outside outwards, sets up the metal connecting ring between inboard steel band and outside steel band, sets up flexible material between the adjacent steel band of inboard steel band, sets up flexible material between the adjacent steel band of outside steel band.
The wound gasket capable of simultaneously bearing internal and external pressure is characterized in that the minimum distance A between the inner steel strip and the outer steel strip ranges from 2mm to 18 mm.
The wound gasket capable of simultaneously bearing internal pressure and external pressure is characterized in that the winding thicknesses of the inner steel belt and the outer steel belt are consistent.
The wound gasket capable of simultaneously bearing internal pressure and external pressure is characterized in that the thickness H of the metal connecting ring is 70% -80% of the thickness H of the wound gasket.
The wound gasket capable of simultaneously bearing internal pressure and external pressure is characterized in that the V-shaped included angle of the steel belt ranges from 15 degrees to 75 degrees.
The wound gasket capable of simultaneously bearing internal pressure and external pressure is characterized in that the flexible material is a non-metal material.
The wound gasket capable of simultaneously bearing internal pressure and external pressure is characterized in that the flexible material is graphite.
The application has the remarkable effects that: because the V-shaped opening of the inner side winding type gasket faces inwards, and the V-shaped opening of the outer side winding type gasket faces outwards, the spiral wound gasket can simultaneously bear medium pressure from the inner direction and the outer direction, and can be used for certain special working conditions requiring to simultaneously bear inner medium pressure sealing and outer medium pressure sealing, such as deep sea application working conditions.
Drawings
FIG. 1 is a prior art wound gasket construction.
Fig. 2 shows an improved wound gasket structure capable of simultaneously bearing internal and external pressure.
In the figure: 1, steel belt; 2 a flexible material; 3 metal connecting rings.
Detailed Description
The present application is further described with reference to the accompanying drawings:
as shown in the attached drawings, the winding type gasket structure is formed by combining two common V-shaped winding type gaskets, wherein a V-shaped opening of the winding type gasket at the inner side faces inwards, a V-shaped opening of the winding type gasket at the outer side faces outwards, the two winding type gaskets are connected into a whole through a middle metal connecting ring, and non-metal materials such as flexible graphite are filled between steel belts. The minimum width A of the metal connecting ring is 2mm, the thicknesses H of the inner and outer wound gaskets are consistent so as to keep the compression amount of the inner and outer wound gaskets consistent, and the thickness H of the metal connecting ring is 70% -80% of the thickness H of the wound gasket so as to control the compression amount of the wound gasket properly.
The realization of the novel technical characteristics is that: because the V-shaped opening of the inner side winding type gasket faces inwards, and the V-shaped opening of the outer side winding type gasket faces outwards, the spiral wound gasket can simultaneously bear medium pressure from the inner direction and the outer direction, and can be used for certain special working conditions requiring to simultaneously bear inner medium pressure sealing and outer medium pressure sealing, such as deep sea application working conditions.
The flexible material is non-metallic material such as graphite.
