Abstract
The utility model provides a fixed type ball valve used fin the metallurgy industry, which comprises a valve cover, a valve seat, a ball body, a sealing ring and a spring, wherein a gap is arranged between the valve seat and the valve cover, the outer lateral surface of the valve seat is provided with a rectangular groove and a supporting sealing ring is arranged in the groove. The contact line of the supporting sealing ring and the valve cover and the sealing line of the sealing ring and the ball body are both on a cone taking the center of the ball body as the vertex of the cone; the cross section of the supporting sealing ring had better forms a subtriangular shape. The utility model has the advantages that the valve seat and the sealing ring has the self centering function, the sealing effect is good and the service life is long.
Description
Affiliated technical field
The utility model relates to a kind of ball valve, specifically a kind of Fixed ball valve.
Background technique
At present the employed Fixed ball valve of metallurgy industry adopts the rigid cylindrical location between valve seat and valve body, can not self-alignment, and easily produce and leak, sealing effect is poor.
Summary of the invention
In order to overcome the deficiency of existing Fixed ball valve sealing effect difference, the utility model provides a kind of Fixed ball valve with Self-centering Action.
The technological scheme that its technical problem that solves the utility model adopts is, a kind of Fixed ball valve, comprise valve gap, valve seat, spheroid, seal ring, spring, gapped between valve seat and the valve gap, outer side surface at valve seat has a rectangle groove, and supporting ring is housed in the groove, and it is on the cone of the vertex of a cone that the potted line of the Line of contact of supporting ring and valve gap, seal ring and spheroid coexists with the ball centre.
The cross section of supporting ring is subtriangular.
The beneficial effects of the utility model are that valve seat, seal ring have Self-centering Action, good sealing effect, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is embodiment's a tectonic maps.
Fig. 2 is the partial enlarged drawing of I among Fig. 1.
Among the figure: 1. valve gap; 2. supporting ring; 3. valve seat; 4. spring; 5. seal ring; 6. spheroid.
Embodiment
As shown in Figure 1, between valve seat 3 and valve gap 1, there is the gap, outer side surface at valve seat 1 has a rectangle groove, supporting ring 2 is housed in the groove, contact for spherical line between supporting ring 2 and the valve gap 1, and the cross section of supporting ring 2 is subtriangular, good rigidly, and it is on the cone of the vertex of a cone that the potted line B of the Line of contact A of supporting ring 2 and valve gap 1, seal ring 5 and spheroid 6 coexists with ball centre O.During action, because gapped between valve gap 1 and the valve seat 3, and OAB is a straight line, and spheroid 6 valve seat 3 and seal ring 5 when moving can be done a small rotation like this, has Self-centering Action, good sealing effect, long service life.
Claims (2)
1, a kind of Fixed ball valve, comprise valve gap, valve seat, spheroid, seal ring, spring, it is characterized in that: gapped between described valve seat and the described valve gap, outer side surface at described valve seat has a rectangle groove, supporting ring is housed in the groove, and it is on the cone of the vertex of a cone that the potted line of the Line of contact of described supporting ring and described valve gap, described seal ring and described spheroid coexists with described ball centre.
2, Fixed ball valve according to claim 1 is characterized in that: the cross section of described supporting ring is subtriangular.
