High pressure attenuator

An attenuator for a high pressure fluid system comprising:

• a body defining a pressure chamber therein, at least one end of the body including an opening to the pressure chamber and having an engaging wall extending axially beyond the opening to the pressure chamber, the engaging wall defining a sealing chamber therein;
• a seal head positioned within the sealing chamber and sealing the opening to the pressure chamber, the seal head including a tapered engaging face that abuts a wedge surface surrounding the opening and having a passageway there through for the passage of a fluid from the pressure chamber;
• a tensioner threadedly coupled to the engaging wall and positioned around the passageway within the sealing chamber;
• and
• a plurality of jackbolts threaded through the tensioner, at least one of the jackbolts having an end contacting the seal head to bias the seal head against the opening to the pressure chamber.

An attenuator for a high pressure fluid system comprising:

• a body defining a pressure chamber therein, at least one end of the body including an opening to the pressure chamber and having an engaging wall extending axially beyond the opening to the pressure chamber, the engaging wall defining a sealing chamber therein and having an outside surface;
• a seal head positioned within the sealing chamber and sealing the opening to the pressure chamber, the seal head having a passageway there through for the passage of a fluid from the pressure chamber;
• a tensioner ring positioned around the outside surface of the engaging wall;
• and
• an end ring positioned around the passageway and coupled to the tensioner ring with a plurality of fasteners that are threaded into the tensioner ring to bias the end ring against the seal head, thereby biasing the seal head against the opening to the pressure chamber.

An attenuator for a high pressure fluid system comprising:

• a body defining a pressure chamber therein, the body including at least one opening to the pressure chamber toward an end of the body and an engaging wall extending axially beyond the opening and defining a sealing chamber therein;
• a seal head positioned within the sealing chamber and including a plug end;
• and
• a tensioner coupled to the engaging wall and biasing the seal head axially toward the pressure chamber, the tensioner positioned to lie axially away from the pressure chamber relative to the plug end and including
• a tensioner ring threadedly coupled to the engaging wall, and
• an end ring coupled to the tensioner ring with a plurality of fasteners that are threaded into the tensioner ring to bias the end ring against the seal head, thereby biasing the seal head axially toward the pressure chamber.
