Abstract
A frame for supporting a pressure relief valve located within a frac line connected to high pressure pumps on frac trucks. A metallic base is formed from rectangular tubing in the shape of a box. Saddles on the base support a tee on the lower portion of the relief valve. Brace links are connected at one end to the corners of the metallic base and swivel about clevises to allow access to the pressure relief valve. The other end of the brace links connect to clevises on a flange when assembled. The flange is rigidly connected to an upper portion of the relief valve to stabilize the assembly. Lifting loops on the flange allow the frame to be lifted during assembly.
Claims20
An apparatus for supporting a pressure relief valve that is attached to a main flow line, comprising:
- a base set on the main flow line, the base comprising:
- at least one lower tube that forms a lower rectangle;
- at least one upper tube that forms an upper rectangle;
- and
- at least one vertical tube extending between and connecting the at least one upper tube to the at least one lower tube;
- at least one saddle mounted to the base, the at least one saddle having an upward facing surface for supporting the main flow line adjacent the pressure relief valve;
- a flange adapted to be secured to an upper portion of the pressure relief valve;
- and
- elongated support members each having a base end pivotingly coupled to the base, and a flange end coupled to the flange;
- wherein the flange ends of the support members are released from the flange, thereby enabling the support members to pivot about the base ends from an inward inclined position with the flange ends fastened to the flange, to an outward position with the flange ends disconnected from the flange, thereby allowing access to the relief valve.
A pressure relief valve assembly, comprising:
- a pressure relief valve connected to a flow line;
- a valve support, comprising:
- a base having front and back lower tubes that are joined to right and left side lower tubes to define a lower rectangle;
- a plurality of cross braces extending between the front and back lower tubes;
- at least one saddle fastened to one of the cross braces and having a surface for supporting the flow line adjacent the pressure relief valve;
- a flange extending around and being secured to an upper portion of the relief valve;
- a plurality of links, each having a lower end pivotally connected to the base and an upper end;
- and wherein
- each of the links is pivotal in a plane through which a vertical axis passes about the lower end from an open position wherein the upper ends of the links are spaced radially outward from the flange, to an inward inclined position wherein the upper ends of the links are connected to the flange.
A pressure relief valve assembly, comprising:
- a pressure relief valve;
- a tee connected to a lower end of the valve adapted for connecting to a frac line;
- a base fabricated from a plurality of tubing members joined end to end to form a box;
- a plurality of saddles fastened to a lower portion of the base, a clamp fastened to each saddle to retain the tee on the saddles;
- a plurality of links, each of the links connected at a lower end to the upper corners of the base by a plurality of clevises, the clevises oriented around the vertical axis of the valve to allow pivoting of the links toward the vertical axis of the valve;
- a pair of flanges each having a plate with a plurality of clevises for connecting the flange to upper ends of the links, the flange closely receiving an upper portion of the relief valve, the flange having a bolt pattern that fastens to a cylinder portion of the relief valve;
- a lifting loop secured onto each of the flanges for allowing lifting of the flanges;
- and
- a lifting eye welded onto a top of the relief valve for lifting.
