Abstract
A method of attenuating pressure pulsations, comprises: pumping liquid into a vessel in fluid communication with a flow line by a conduit sealingly passing through a top surface of the vessel, so as to discharge the liquid into the flow line while creating an air-liquid interface in the vessel, by trapping in an upper part of the vessel air that attenuates pressure pulsations caused by the pumping. The method also comprises generating condition for the liquid to drain out of the vessel to allow air to fill at least the upper portion of the vessel.
Claims22
A method of attenuating pressure pulsations, comprising:
- pumping liquid by a pump into a vessel in fluid communication with a flow line by a conduit sealingly passing through a top surface of said vessel, so as to discharge said liquid into said flow line while creating an air-liquid interface in said vessel, by trapping in an upper part of said vessel air that attenuates pressure pulsations caused by said pumping;
- and
- generating condition for said liquid to drain out of said vessel to allow air to fill at least said upper portion of said vessel.
A system for attenuating pressure pulsations, comprising:
- a vessel having a top surface, an upper part and a lower part;
- a conduit in fluid communication with said lower part, said conduit sealingly passing through said top surface to feed a flow line outside said vessel with liquid;
- a liquid inlet formed in said vessel for receiving said liquid from a pump in a manner that said liquid enters both said vessel and said conduit, and creates an air-liquid interface in said vessel, by trapping in said upper part air that attenuates pressure pulsations generated by said pump;
- and
- at least one drain opening constituted to drain said liquid out of said vessel and to allow air to fill at least said upper portion of said vessel.
A valve device, comprising:
- a valve body formed with an opening;
- a peripheral sealing member positioned within said valve body and being movable towards and away from said opening;
- and
- two liquid ports formed at opposite sides of said valve body, and being sealingly connectable to liquid conduits;
- wherein said peripheral sealing member is positioned and configured such that inflow of liquid through said first port biases said sealing member against said opening, and inflow of liquid through said first port releases said sealing member from said opening.
