Изобретение относитс к приборостроению , в частности к устройствам дл испытаний датчиков давлени .The invention relates to instrumentation, in particular to devices for testing pressure sensors.
Известны устройства создани пульсаций давлени Т,Known devices for creating pressure pulsations T,
Однако они сложны по конструкции и не экономичны.However, they are complex in design and not economical.
Наиболее близким по технической сущности и достигаемому эффекту к предлагае юму вл етс устройство, JQ содержащее источник высокого давлени , соединенный с линией высокого давлени , включающей в себ золотниковый переключатель .и линией низкого давлени с редуктором - с выход- 15 ной линией t21.The closest in technical essence and the achieved effect to the proposed is a device JQ containing a high pressure source connected to a high pressure line including a spool switch and a low pressure line with a reducer from the output line t21.
Известное устройство также неэкономично , так как рабоча среда при работе устройства выбрасываетс 20 в атмосферу.The known device is also uneconomical, since the working medium during operation of the device is emitted 20 into the atmosphere.
Цель изобретени - повышение экономичности устройства за счет уменьшени в нем расхода рабочей среды.The purpose of the invention is to increase the efficiency of the device by reducing the consumption of the working medium.
Поставленна цель достигаетс тем, что в устройстве дл динамических ис пытаний датчиков давлени , содержащем источник высокого давлени , соединенный с линией высокого давлени , включающей в себ золотниковый переключатель и линией низкого давлени с редуктором - с выходной линией, золотниковый переключатель выполнен трехпозиционным , а в линию низкого д« члени введен обратный клапан, установленный между выходной.линией и сливной линией золотника, подключенной к линии низкого давлени .The goal is achieved by the fact that in a device for dynamic testing of pressure sensors containing a high pressure source connected to a high pressure line, including a spool switch and a low pressure line with a reducer, to an output line, the spool switch is three-position, and the line a low d "valve" is inserted a check valve installed between the outlet line and the spool drain line connected to the low pressure line.
На чертеже показана принципиальна схема предлагаемой установки.The drawing shows a schematic diagram of the proposed installation.
Источник 1 гидравлического давлени соединен с ветвью 2 высокого давлени и через редукционный клапан 3 с ветвью низкого давлени .The hydraulic pressure source 1 is connected to a high pressure branch 2 and through a pressure reducing valve 3 to a low pressure branch.
