Description
Technical Field
The utility model relates to a valve, concretely relates to high pressure ball valve that floats.
Background
Ball valve refers to a valve in which the opening and closing element is a sphere and is driven by a valve rod to rotate around the axis of the ball valve. It can be used for regulation and control of fluid. The ball valve has both a floating ball valve and a fixed ball valve, wherein the ball of the floating ball valve is floating, and when the ball valve is in a closed position, the pressure of the medium at the inlet end acts on the ball to generate a force pushing the ball to make the ball generate a small displacement, and the pressure presses the valve seat at the outlet end to generate a contact stress on the conical surface of the valve seat to form a contact zone to generate sealing.
A conventional floating ball valve is shown in fig. 3, in which an annular mounting groove is formed in a valve body, a valve seat is inserted into the annular mounting groove, and when the ball valve is in a closed position, a specific sealing pressure between the valve seat and the bottom of the annular mounting groove in the valve body is equivalent to a specific sealing pressure on a contact surface between the valve seat and the ball body, so that reliable sealing can be ensured.
However, the above structure is generally applicable to a medium-low pressure environment, but is not applicable to a high-pressure environment, because when the pressure increases with the increase of the caliber, the above structure hardly ensures that the specific sealing pressure at the bottom of the annular mounting groove on the valve seat and the valve body is equivalent to the specific sealing pressure on the contact surface of the valve seat and the ball, thereby easily causing the medium to leak from the gap between the valve seat and the valve body.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of background art, the utility model provides a high pressure ball valve that floats.
The utility model discloses the technical scheme who adopts: a high-pressure floating ball valve comprises a valve body, a ball body, a valve rod and a valve seat, wherein the ball body is arranged in the valve body and is in linkage connection with the valve rod; an annular mounting groove for mounting the valve seat is formed in the valve body, and a plurality of annular vertex angles are formed on the bottom surface of the annular mounting groove; one end of the valve seat is provided with a conical sealing surface which can be in sealing fit with the ball body, and the other end of the valve seat is provided with an annular groove matched with the vertex angle; the valve seat is embedded in the annular mounting groove, and the annular groove of the valve seat is embedded with the vertex angle.
The cross section of the vertex angle is triangular.
The angle of the apex angle is 60 °.
The height of the top angle is 1-2 mm.
The utility model has the advantages that: scheme more than adopting increases the cooperation of inlaying of apex angle and recess between valve body and the disk seat, can effectively improve the sealed specific pressure between valve body and the disk seat under the high pressure condition to guarantee sealed reliable can not reveal, also satisfy low-medium pressure environment simultaneously and use, effectively reduce and reveal.

Detailed Description
The embodiments of the present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-2, a high-pressure floating ball valve comprises a valve body 1, a ball body 2, a valve rod 3 and a valve seat 4, wherein the ball body 2 is arranged in the valve body 1, one end of the valve rod 3 extends into the valve body 1 and is connected with the ball body 2 in a linkage manner, and the other end of the valve rod is connected with a driving device.
An annular mounting groove 11 for mounting the valve seat 4 is formed in the valve body 1, 3 annular vertex angles 12 are formed on the bottom surface of the annular mounting groove 11, the cross sections of the vertex angles 12 are triangular, the angle of each vertex angle 12 is 60 degrees, and the height of each vertex angle is 1-2 mm.
One end of the valve seat 4 is provided with a conical sealing surface 41 which can be in sealing fit with the ball body 2, and the other end is provided with an annular groove 42 which is matched with the vertex angle 12; the valve seat 4 is embedded in the annular mounting groove 11, and the annular groove 42 is embedded with the top corner 12.
The number, angle and height of the top angles 12 and the annular grooves 42 can be slightly adjusted according to the actual process requirements.
When the ball valve is in the closed position, the medium pressure at the inlet end acts on the ball body 2 to generate a force for pushing the ball body 2, so that the ball body 2 generates a small displacement and presses the valve seat 4 at the outlet end, and a contact stress is formed between the conical sealing surface 41 of the valve seat 4 and the ball body 2, thereby forming a reliable seal.
Simultaneously, disk seat 4 closely laminates with valve body 1 under the effect of spheroid 2, because inlay the cooperation through apex angle 12 and annular groove 42 between valve body and 1 disk seat 4, thereby even make under high pressure environment, still can keep the sealed specific pressure equivalent with disk seat and spheroid contact between disk seat 4 and the valve body and 1, can effectively improve the sealed specific pressure between valve body and the disk seat under the high pressure condition, thereby guarantee sealed reliable can not reveal, also satisfy low-medium pressure environment simultaneously and use, effectively reduce and reveal.
