Abstract
Exemplary embodiments are directed to butterfly valves, generally including a body assembly and a locking cap. The body assembly generally includes a body, a disc rotationally disposed inside an opening of the body, a cog, and a stem passing through the disc and the body. The locking cap generally engages the cog to prevent rotation of the disc and the stem relative to the body. Methods of assembling and positioning a butterfly valve are also provided.
Claims24
A butterfly valve, comprising:
- a body assembly, the body assembly including a body, a disc rotationally disposed inside an opening of the body, a cog interlocked with the body, and a stem passing through the disc and the body, and
- a locking cap including an outer surface with a protrusion extending therefrom,
- wherein the cog and the locking cap comprise complementary splines engageable relative to each other;
- wherein the locking cap engages the cog to prevent rotation of the disc and the stem relative to the body, and
- wherein during engagement of the locking cap and the cog, the protrusion of the locking cap is indicative of a position of the butterfly valve.
A method of assembling a butterfly valve, comprising:
- providing a body assembly, the body assembly including a body, a disc rotationally disposed inside an opening of the body, a cog interlocked with the body, and a stem passing through the disc and the body,
- providing a locking cap, the locking cap including an outer surface with a protrusion extending therefrom, and
- engaging complementary splines of the locking cap with complementary splines of the cog to prevent rotation of the disc and the stem relative to the body,
- wherein during engagement of the locking cap and the cog, the protrusion of the locking cap is indicative of a position of the butterfly valve.
A butterfly valve, comprising:
- a body assembly, the body assembly including a body, a disc rotationally disposed inside an opening of the body, a cog, and a stem passing through the disc and the body, and
- a removable locking cap assembly, the removable locking cap assembly including a locking cap and a cap bezel,
- wherein the removable locking cap engages the cog to prevent rotation of the disc and the stem relative to the body,
- wherein the cap bezel removably engages the locking cap to prevent the locking cap from being disengaged from the cog.
A butterfly valve, comprising:
- a body assembly, the body assembly including a body, a disc rotationally disposed inside an opening of the body, a cog, and a stem passing through the disc and the body, and
- a removable locking cap assembly, the removable locking cap assembly including a locking cap and a cap bezel,
- wherein the locking cap engages the cog to prevent rotation of the disc and the stem relative to the body, the cap bezel removably engages the locking cap to prevent the locking cap from being disengaged from the cog, and disengagement and removal of the locking cap from the body assembly is needed before changing a position of the disc and the stem relative to the body.
