Abstract
A frac system including a frac tree. The frac tree includes a frac head. The frac head defines a first inlet, a second inlet, and an outlet. The frac head receives frac fluid through the first inlet and directs the frac fluid to the outlet fluidly coupled to a wellhead. A valve couples to the second inlet of the frac head. A flapper valve is within the frac head. The flapper valve moves between an open position and a closed position to control fluid flow to the valve through the second inlet. The flapper valve aligns with a first axis of the outlet and the second inlet in the closed position and aligns with a second axis of the first inlet in the open position.
Claims22
A system comprising:
- a body having a stem aperture with an aperture axis, a first port, a second port, and a fluid flow path between the first and second ports;
- a flapper valve within the body, wherein the flapper valve is configured to move between an open position and a closed position to open and close the fluid flow path;
- and
- a stem disposed in the stem aperture and extending along a stem axis coaxial with the aperture axis, wherein the stem axis and the aperture axis are oriented at an angle crosswise to a central axis of the fluid flow path, and the stem is configured to move axially along the stem axis and the aperture axis within the stem aperture to move the flapper valve between the open position and the closed position.
A system, comprising:
- a body having a stem aperture, a first port, a second port, and a fluid flow path between the first and second ports;
- a flapper valve within the body, wherein the flapper valve is configured to move between an open position and a closed position to open and close the fluid flow path;
- and
- a stem disposed in the stem aperture and extending along a stem axis, wherein the stem axis is oriented at a constant angle crosswise and not perpendicular to a central axis of the fluid flow path, and the stem is configured to move along the stem axis at the constant angle within the stem aperture to move the flapper valve between the open position and the closed position.
A system, comprising:
- a body having a stem aperture, a first port, a second port, and a fluid flow path between the first and second ports;
- a flapper valve within the body, wherein the flapper valve is configured to move between an open position and a closed position to open and close the fluid flow path;
- and
- a stem disposed in the stem aperture and extending along a stem axis from an exterior to an interior of the body, wherein the stem axis is oriented at an angle crosswise to a first rotational axis of the flapper valve, and the stem is configured to move axially along the stem axis within the stem aperture to move the flapper valve between the open position and the closed position.
