(Л СThe invention relates to the field of mechanical engineering and can be used in industries that are associated with the protection of devices against pressure pulsations and hydraulic shocks in hydraulic lines. The purpose of the invention is to increase the efficiency of the device. During the operation of the damper, the working medium at steady motion of the fluid fills the cavities (P) 2 and 3 of the damper, as well as channels (K) 11, 12 and cavities formed by surfaces 9, 15 and 10, 15, made in the form of a protrusion cavities, such as threaded connections.

The connection of the disks 6 and 7 by a rigid connection 8 makes it possible to adjust simultaneously the volumes of the damping P 2 and 3, thereby providing adjustment of the damper to dampen the required frequency range of pressure pulsations, and by performing the lengths K 11 and 12 and the locations of the holes 4, 13, 5, 14 provides the required degree of quenching of the overpressure 1 sludge.

Цель изобретени - повышение эффективности функционировани устройства.The purpose of the invention is to increase the efficiency of the device.
На чертеже представлен демпфер колебаний давлени дл манометра.The drawing shows a pressure oscillation damper for a pressure gauge.
Демпфер содержит корпус 1 с демпфирующими полост ми 2 и 3, сообщающимис дросселирующими отверсти ми 4 и 5, диски 6 и 7 с жесткой св зью 8 и цилиндрическими поверхност ми 9 и 10, каналами 11 и 12 с отверсти ми 13 и 14, цилиндрическую поверхность корпуса 15.The damper includes a housing 1 with damping cavities 2 and 3, connected by throttling holes 4 and 5, disks 6 and 7 with a rigid connection 8 and cylindrical surfaces 9 and 10, channels 11 and 12 with holes 13 and 14, a cylindrical surface housing 15.
Демпфер работает следующим образом .The damper works as follows.
Рабоча среда при установившемс движении жидкости заполн ет полости демпфера 2 и 3, а также каналы 11 и 12 и полости, образованные поверхност ми 9, 15 и 10, 15, выполненными в виде выступа - впадины, например резьбовые соединени . При возникновении перед диском 7 гидравлического удара или пульсаций давлени избыточное давление поступает в канал 12, далее к отверстию 5, где частично гаситс . Затем поступает в демпфирующую полость The working medium in case of steady motion of the fluid fills the cavities of the damper 2 and 3, as well as the channels 11 and 12 and the cavities formed by the surfaces 9, 15 and 10, 15, made in the form of a protrusion - a depression, for example threaded connections. If a water hammer or pressure pulsation occurs in front of the disk 7, the overpressure enters the channel 12, then to the hole 5, where it is partially quenched. It then enters the damping cavity.
3, канал 11, отверстие 4 и окончательно гаситс в полости 2, защища таким образом измерительный прибор, например манометр .3, channel 11, hole 4 and finally extinguished in cavity 2, thus protecting a measuring device, such as a pressure gauge.
Соединение дисков 6 и 7 жесткой св зью 8 позвол ет регулировать одновременно объемы демпфирующих полостей 2 и 3, обеспечива тем самым регулировку демпфера на гашение требуемого диапазона частот пульсаций давлени , а выполнением длин каналов 11 и 12 и мест размещени отверстий 4, 13 и 5, 14, обеспечивать требуемую степень гашени избыточного давлени .The connection of the disks 6 and 7 with a rigid connection 8 makes it possible to simultaneously adjust the volumes of the damping cavities 2 and 3, thereby providing adjustment of the damper to quench the required frequency range of pressure pulsations, and performing the lengths of channels 11 and 12 and the locations of the holes 4, 13 and 5, 14, to provide the required degree of quenching of the overpressure.
