Изобретение относитс к области измерительной те.хники, а именно к грузопоршневым приборам дл автоматического воспроизведени абсолютного (и избыточного) давлени , и может быть применено при построении автоматических образцовых грузопоршневых приборов, предназначенных в метрологи дл поверки рабочих .мановакуу.мметров дл датчиков давлени различных типов , а также в других област х измерительной техники, пневматики и т. п.The invention relates to the field of measurement technology, namely, cargo-piston devices for automatic reproduction of absolute (and excess) pressure, and can be applied in the construction of automatic model cargo-piston devices designed in metrology for the calibration of working manometers / meters for pressure sensors of various types , as well as in other areas of measurement technology, pneumatics, etc.
По основному авт. св. № 669235 известен грузопорцпгевой мановакуум.метр абсолютного давлени , содержащий цилиндр, в котором установлен неуплотненный полый поршень с платформой нагружени , механизм уравновешивани и систему регулировани давлени .According to the main author. St. No. 669235 is known for a cargo pressure absolute pressure manovacuum meter comprising a cylinder in which an unconsolidated hollow piston is installed with a loading platform, a balancing mechanism and a pressure control system.
Недостатком его вл етс низка устойчивость системы регулировани давлени , что приводит к необходимости подключени к ней дополнительного ресивера, снижающего уровень возникающих в системе пульсаций .Its disadvantage is the low stability of the pressure control system, which leads to the need to connect an additional receiver to it, which reduces the level of the pulsations arising in the system.
Целью изобретени вл етс повышение точности измерени за счет повышени устойчивости системы регулировани давлен .ч .The aim of the invention is to improve the measurement accuracy by increasing the stability of the pressure control system.
Указанна цель достигаетс тем, что в полость поршн введена дроссельна шайба , установленна между его нижним тор-цом и отверстием в боковой стенке.This goal is achieved by inserting a throttle washer into the piston cavity, which is installed between its lower end and a hole in the side wall.
На чертеже приведена принципиальна схема грузопоршневого мановакуумметра абсолютного давлени .The drawing shows a schematic diagram of an absolute pressure cargo piston manometer.
Грузопоршневой мановакуумметр состоит из цилиндров 1 и 2, в которых установлен неуплотнеиный полый, открытый с нижнего торца поршень 3 с платформой 4 нагружени и груза.ми 5. В полости цилиндра 1 торцом поршн 3 образована камера 6 опорного давлени . Полость поршн разделена дроссельной шайбой 7 с отверстием 8 на две камеры; внутреннюю демпфирующую камеру 9. и внешнюю, совмещенную с камерой 10 обратной св зи.Cargo piston man-vacuum meter consists of cylinders 1 and 2, in which a non-compacted hollow piston 3 open at its lower end is installed with a loading platform 4 and cargo 5. In the cavity of cylinder 1, the end face of piston 3 is formed by a chamber 6 of the reference pressure. The piston cavity is divided by a throttle washer 7 with an opening 8 into two chambers; an internal damping chamber 9. and an external one combined with a feedback chamber 10.
Систе.ма регулировани давлени включает регулируемый дроссель, который образован отверсти ми И и 12 в стенке цилиндра 2, проточкой 13 с отверсти ми в стенкеThe pressure control system includes an adjustable throttle which is formed by the holes And and 12 in the wall of the cylinder 2, by the groove 13 with the holes in the wall
