Description
Изобретение относитс к машиностое- нию и может быть использовано в энергетике , нефтехимии, тепловодоснабжении и канализации .The invention relates to machinery stand and can be used in power engineering, petrochemistry, heat and water supply and sewage.
Целью изобретени вл етс повышение эффективности устройства путем расширени диапазона одновременно гасимых амплитуд пульсаций давлени .The aim of the invention is to increase the efficiency of the device by expanding the range of simultaneously suppressed amplitudes of pressure pulsations.
На чертеже представлен гаситель пульсаций давлени .The drawing shows a pressure pulsation damper.
Гаситель содержит корпус 1 с установленными в нем подвод щим 2 и отвод щим 3 патрубками. В корпусе 1 установлен трубопровод 4 с отверсти ми 5 дл прохода жидкости , который охвачен эластичной мембраной 6, выполненной, например, из резины с площадью поперечного сечени , уменьшающейс от входного 2 к выходному 3 патрубкам. Эластична мембрана 6 опираетс на упругий элемент 7, выполненный в виде набора продольных пластин, предназначенных дл предохранени эластичной мембраны 6 от вдавливани в отверсти 5 трубопровода 4.The damper includes a housing 1 with inlet 2 installed therein and with 3 outlet pipes. A housing 4 is provided with a pipe 4 with apertures 5 for the passage of fluid, which is enclosed by an elastic membrane 6 made, for example, of rubber with a cross-sectional area decreasing from the inlet 2 to the outlet 3. The elastic membrane 6 rests on an elastic element 7, made in the form of a set of longitudinal plates designed to protect the elastic membrane 6 from being pressed into the holes 5 of the conduit 4.
Полость 8, образованна между наружной поверхностью мембраны 6 и внутренней поверхностью корпуса 1, сообщена черезThe cavity 8, formed between the outer surface of the membrane 6 and the inner surface of the housing 1, communicates through
штуцер 9 с источником сжатого газа (не показан). Полость 8 герметизирована с помощью двух вставок 10 и крыщек 11 и 12, выполненных заодно с подвод щим 2 и отвод щим 3 патрубками соответственно. Под- жатие крышек 11 и 12 осуществл етс с помощью двух гаек 13.fitting 9 with a source of compressed gas (not shown). The cavity 8 is sealed by means of two inserts 10 and caps 11 and 12, integral with the inlet 2 and the outlet 3 with nozzles, respectively. The clamping of the caps 11 and 12 is carried out with the help of two nuts 13.
Гаситель пульсаций давлени работает следующим образом.The pressure pulsation damper works as follows.
При отсутствии пульсаций давлени рабоча жидкость проходит через подвод щий патрубок 2, перфорированный трубопровод 4 и отвод щий патрубок 3 практически без изменени ее давлени . В случае возникновени пульсаций давлени рабоча жидкость проходит через отверсти 5, раздвигает пластины упругого элемента 7 и взаимодействует с эластичной мембраной 6 и газовой полостью 8. При этом энерги пульсаций давлени рассеиваетс . Благодар переменной по потоку площади поперечного сечени эллстичной мембраны 6 волны давлени , которые обычно распростран ютс от подающих жидкость устройств (напри.мер насосов), эффективо гас тс по всей длине перфорированного трубопровода 4, так как их амплитуда уменьшаетс от входного 2 к выходному 3 патрубку.In the absence of pressure pulsations, the working fluid passes through the inlet pipe 2, the perforated pipe 4 and the outlet pipe 3 with practically no change in its pressure. In the case of pressure pulsations, the working fluid passes through the holes 5, pushes the plates of the elastic element 7 and interacts with the elastic membrane 6 and the gas cavity 8. In this case, the energy of the pressure pulsations is dissipated. Due to the variable cross-sectional area of the Ellastic membrane 6, the pressure waves, which usually propagate from the liquid supplying devices (for example, pumps), are effectively absorbed along the entire length of the perforated conduit 4, since their amplitude decreases from the inlet 2 to the outlet 3 .
