Abstract
A ball valve having a seal that is less prone to damage is provided. The seal is substantially captured by a retainer and a housing portion of the ball valve, wherein only a small portion of the seal is exposed and in contact with the ball. Accordingly, the seal is less likely to bulge towards the ball and rotation of the ball associated with valve opening and closing will not damage the seal.
Claims16
A ball valve sealing system comprising:
- a retainer configured to be positioned between a housing of a ball valve and a fluid line or a connector associated therewith, the retainer having a lateral surface of a first length associated with an angled surface of a second length;
- a sealing member having a triangular profile comprising a lateral surface of a third length, an angled surface of a fourth length, and an inner surface, wherein the inner, lateral, and angled surfaces of the sealing member are interconnected by rounded surfaces;
- wherein the first length and third lengths are substantially the same, and the second and fourth lengths are substantially the same, wherein the retainer surrounds a majority of the sealing member;
- and
- wherein the length of the inner surface is substantially the same as the third length.

A ball valve comprising:
- a housing having a fluid inlet and a fluid outlet, the fluid inlet and fluid outlet configured to be interconnected to a fluid line:
- a ball with a channel therethrough positioned with the housing:
- a stem interconnected to the ball and operatively interconnected to the housing, wherein rotation of the stem rotated the ball to selectively align the channel with the fluid inlet and fluid outlet:
- a retainer configured to be positioned between the housing of the ball valve and the fluid line or a connector associated therewith, the retainer having a lateral surface of a first length associated with an angled surface of a second length;
- a sealing member having a triangular profile comprising a lateral surface of a third length, an angled surface of a fourth length, and an inner surface;
- and
- wherein the first length and third lengths are substantially the same, and the second and fourth lengths are substantially the same, wherein the retainer surrounds a majority of the sealing member.
