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;
- a flange on a portion of the pressure relief valve distal from the main flow line;
- elongated support members each having a base end pivotingly coupled to the base and a flange end pivotingly coupled to the flange;
- and
- selectively removable couplings for linking an end of the support members to the flange and an opposing end to the base, so that when a coupling is removed from an end of one of the support members to define a free end, the support member is rotatable about an axis defined by the coupling on the support member opposite the free end and allow access to the relief valve.
A pressure relief valve assembly, comprising:
- a pressure relief valve,
- a hydraulic operator on an upper end of the valve;
- a tee connected to a lower end of the valve connected to a frac line;
- a base;
- a plurality of saddles fastened to the base and having a curved recess in which the tee is set;
- a plurality of links, each having a lower end connected to the base;
- and
- a flange having a plate with a plurality of clevises connected to an upper end of the links, the flange adapted to closely receive a top end of the relief valve.
A pressure relief valve assembly, comprising:
- a pressure relief valve,
- a hydraulic operator for operating the valve located on an upper end of the valve;
- a tee connected to a lower end of the valve adapted for connecting to a frac line;
- a metallic base fabricated from a plurality of rectangular tubing members joined end to end to form a box;
- a plurality of saddles fastened to a lower portion of the metallic base, a clamp fastened to each saddle to retain the tee on the saddles;
- a plurality of links, each of links connected at one end to the upper corners of the metallic base by a plurality of clevises, the clevises oriented inward at 45 degrees and allowing the each of the links to swivel;
- a pair of flanges having a plate with a plurality of clevises for connecting to each end of the free end of the links, the flange adapted to closely receive a top end of the relief valve, the flange having a bolt pattern for fastening to the cylinder portion of the relief valve;
- and
- a lifting loop welded onto each of the flanges for allowing lifting;
- and
- a lifting eye welded onto the top of the cylinder for lifting.
