Abstract
The application belongs to technical field of sealing technology, and in particular to a kind of spiral wound gasket structure.A kind of spiral wound gasket suitable for outer means of press seals, including steel band and soft graphite, wherein steel band is V-arrangement steel band, by V-arrangement steel strip winding, the filling flexible graphite between steel band.The remarkable result of the application is: since the direction of the V-notch of V-arrangement steel band facing away from gasket outer circle center line, when gasket bears medium external pressure, external pressure medium, which makees in V-notch, can increase gasket seal load, to be conducive to the sealing performance in medium external pressure.
Description
Technical field
The application belongs to technical field of sealing technology, and in particular to a kind of spiral wound gasket structure.
Background technique
Common spiral wound gasket structure using V-arrangement steel strip winding as shown in Figure 1, formed, the filling flexible between steel band
The nonmetallic materials such as graphite, the direction of the V-notch of the V-arrangement steel band of this spiral wound gasket face gasket outer circle center line,
To with the good sealing performance for bearing medium internal pressure.
The shortcomings that this spiral wound gasket: the sealing being unfavorable in the case of gasket receiving medium external pressure.
Summary of the invention
The purpose of the application is in view of the drawbacks of the prior art, to provide a kind of spiral wound gasket structure, so that when bearing to be situated between
Gasket has good sealing performance when matter external pressure.
The technical solution of the application is: a kind of spiral wound gasket suitable for outer means of press seals, including steel band and soft graphite,
Wherein steel band is V-arrangement steel band, by V-arrangement steel strip winding, the filling flexible graphite between steel band.
A kind of spiral wound gasket suitable for outer means of press seals as described above, wherein the V-notch of the V-arrangement steel band
Direction facing away from gasket outer circle center line.
The remarkable result of the application is: since the direction of the V-notch of V-arrangement steel band facing away from gasket outer circle center line, when
When gasket bears medium external pressure, external pressure medium, which makees in V-notch, can increase gasket seal load, to be conducive in medium external pressure
In the case of sealing performance.
Detailed description of the invention
Fig. 1 spiral wound gasket structure in the prior art.
Fig. 2 is suitable for the spiral wound gasket of outer means of press seals.
In figure: 1 steel band;The nonmetallic materials such as 2 soft graphites.
Specific embodiment
The application is described further with reference to the accompanying drawing:
As shown in attached drawing 1,2, a kind of spiral wound gasket structure is formed using V-arrangement steel strip winding, is filled between steel band soft
Nonmetallic materials, the directions of the V-notch of V-arrangement steel band such as property graphite facing away from gasket outer circle center line.
Realize that technical characterstic of the invention has: a kind of spiral wound gasket structure is formed using V-arrangement steel strip winding, in steel band
Between nonmetallic materials, the direction of the V-notch of V-arrangement steel band such as filling flexible graphite facing away from gasket outer circle center line.Due to V
The direction of the V-notch of shape steel band facing away from gasket outer circle center line, and when gasket bears medium external pressure, external pressure medium makees in V
V notch v can increase gasket seal load, to be conducive to the sealing performance in medium external pressure.
