Abstract
A pressure relief valve is provided that includes a valve housing, a poppet valve and a damper. The valve housing includes a valve seat and a bore. The poppet valve includes a head and a stem. The head is configured to engage the valve seat when the poppet valve is in a closed position. The head is configured to disengage the valve seat when the poppet valve is in an open position. The stem projects axially out from the head and through the bore. The damper includes a damper chamber axially between the valve housing and the head.
Claims20
A pressure relief valve, comprising:
- a valve housing including a valve seat and a bore;
- a poppet valve including a head and a stem, the head configured to engage the valve seat when the poppet valve is in a closed position, the head configured to disengage the valve seat when the poppet valve is in an open position, and the stem projecting axially out from the head and through the bore;
- and
- a damper comprising a damper chamber axially between the valve housing and the head.
A pressure relief valve, comprising:
- a valve housing including a flowpath and a valve seat, the flowpath extending through the valve housing from a flowpath first end to a flowpath second end, the flowpath first end located at the valve seat;
- a valve element configured to move axially between a closed position and an open position, the valve element configured to engage the valve seat when the valve element is in the closed position to close the flowpath at the flowpath first end, the valve element configured to disengage the valve seat when the valve element is in the open position to open the flowpath at the flowpath first end;
- and
- a fluid damper comprising a damper chamber disposed at the flowpath first end.
A pressure relief valve, comprising:
- a valve housing including a valve mount, an outer wall and a flowpath, the valve mount comprising a bore, the outer wall circumscribing and radially spaced from the valve mount, the outer wall comprising a valve seat, the flowpath radially between the valve mount and the outer wall, and the flowpath extending through the valve housing;
- and
- a valve element including a head, a stem and a sleeve, the head configured to engage the valve seat and close the flowpath when the valve element is in a closed position, the head configured to disengage the valve seat and open the flowpath when the valve element is in an open position, the stem projecting axially out from the head and through the bore, and the sleeve circumscribing and radially spaced from stem;
- the valve mount radially between stem and the sleeve;
- a chamber formed by and axially between the valve mount and the head;
- and
- a channel formed by and radially between the valve mount and the sleeve, the channel fluidly coupling the chamber with the flowpath.
