摘要： The invention provides a metal bellows type accumulator having an outer shell provided in its one end with a pressure introducing passage in an opening manner, and a metal bellows repeatedly formed peak portions directed to an outer side in a radial direction and trough portions directed to an inner side, capable of expanding and contracting in an axial direction and separating an inner chamber of the outer shell into a pressure introducing chamber communicated with the pressure introducing passage and a gas chamber charged with cushion gas. A tubular portion is provided at a position where an amplitude of vibration in a radial direction becomes maximum in the metal bellows, has a greater diameter than a maximum diameter portion of each of the peak portions and is in contactable with an inner peripheral surface of the outer shell at a predetermined width in the axial direction.

摘要： The invention relates to the field of physics—namely, to control systems and the pressure control of liquids and gases, in particular—to stabilizing devices operating at overloads, including hydraulic shocks. Technical result from use of the claimed invention is simplicity of the manufacturing process and assembly, easiness of operation and efficiency of quenching pulses. A method consists of the fact that at the section of said pipeline installed at least one pressure pulse stabilizer in the direction of movement of transferred medium from supplier to consumer. Pulse flow is directed as a first portion into the stabilizer, and after its first portion a second portion of the flow is directed, which after a delay is sent into additional input of the stabilizer. The potential sources of pressure pulses are preliminary revealed on the protected section of the pipeline. Then the place of installation of the stabilizer is defined based on condition—at a distance no further than 10 meters from the potential point source of pressure pulses and on condition—at a distance 100-1000 meters during preventive installation on the road, at least two stabilizers on the stage. Stabilizers are oriented on the pointer on its outer surface toward the potential point source of the pressure pulses and the arrows pointed in the same direction as the direction of flow of the transferred medium at the stages. Stabilizers have straight flow chamber for at least ⅓ less than largest vortex chamber, between the casing and shell—pressurized chamber connected via radial openings with straight flow chamber and the equalizing chamber, which connected via inclined holes with the vortex chamber. The diameter of the radial openings is 1.2-4 of the diameter of inclined holes. The angles α and β of inclined holes—in the range 0-45°. Pressure in the pressure and in the levering chambers is equalized by shifting the pistons by the springs to the original position. Different options are offered for killing of pressure pulse by different means, associated with variations in the design of elements of the stabilizer.

摘要： A plunger pressure accumulator includes a shell; and a plunger which is adapted to move relative to the shell into an interior space of the shell. The interior space is divided into at least two subspaces, a first subspace of which is suppliable with hydraulic fluid of an external system and a second subspace which is provided with a pressurized gas. Between the plunger and the shell is arranged a slide element upon which the plunger is supported to move to a distance apart from an internal surface of the first subspace and from an internal surface of the second subspace. The plunger pressure accumulator is provided with at least one regenerator which is stationary relative to the shell or the plunger.

摘要： A method of shutting down a nuclear reactor may include compressing a scram gas that is in fluid communication with a scram accumulator. The scram accumulator defines a chamber therein and contains bellows within the chamber. The bellows are configured to hold a scram liquid in isolation of the scram gas. The scram gas exerts a compressive force on the bellows in a form of stored energy. The method may additionally include releasing the stored energy in response to a scram signal such that the scram gas expands into the chamber of the scram accumulator to compress the bellows and expel the scram liquid from the scram accumulator to insert control rods into a core of the nuclear reactor.
