Description
Предметом изобретени вл етс приспособление дл тарировани безынерционных манометров, нредназначенных дл замера кратковременных импульсов давлени .The subject of the invention is a device for calibrating instantaneous pressure gauges, intended for measuring short-term pressure pulses.
Отличительной особенностью описываемого приснособлени по сравнению с известными тарировочными устройствами вл етс то, что оно выполнено в виде двух камер, к одной из которых присоединен контрольный , к другой-тарируемый манометр. Камеры разделены мембраной , разрываемой дл передачи импульса давлени тарируемому манометру . A distinctive feature of the described device as compared with the known calibration devices is that it is made in the form of two chambers, one of which is connected to the control, to the other is a calibrated manometer. The chambers are separated by a membrane that is broken to transmit a pressure pulse to a calibrated manometer.
На чертеже изображен продольный разрез тарировочного приспособлени .The drawing shows a longitudinal section of the calibration device.
В корпусе 1 при помощи диафрагмы 2, втулки 3 и гайки 4 укреплена мембрана 5, отдел юща камеру А от камеры Б, к которой присоедин етс тарируемый манометр 6. Камера А соедин етс при помощи вентил 7 с баллоном сжатого газа или с воздухопроводом компрессорной линии. Давление в камере А провер етс контрольным манометром 5.In case 1, diaphragm 5 is fixed to diaphragm 2, bushing 3 and nut 4, separating chamber A from chamber B to which a calibrated pressure gauge 6 is connected. Chamber A is connected via valve 7 to a compressed gas cylinder or to an air duct of a compressor line . The pressure in chamber A is checked with a reference pressure gauge 5.
Через отверстие в гайке 4, в камеру Б пропущен ударник 9, снабженный головкой 10 и пружиной и,Through the hole in the nut 4, in the chamber B, the drummer 9, equipped with a head 10 and a spring, is passed through and,
Тарирование манометров при помощи этого приспособлени может выполн тьс двум способами.Calibration of gauges using this tool can be done in two ways.
1.В камере А создаетс давление, повыщаемое до момента разрыва калиброванной мембарны 5, и по контрольному манометру 8 регистрируетс статическое давление в момент, предществующий разрыву.1. In chamber A, a pressure is created that rises until the moment of rupture of the calibrated membrane 5, and the static pressure gauge 8 is recorded at the moment before the rupture.
2.В камере Л создаетс заданное давление, контролируемое по ма-нометру 8, после чего коротким ударом молотка по головке ударника 9 производитс разрыв мембраны 5.2. In chamber L, a predetermined pressure is created, controlled by the gauge 8, after which a short blow of the hammer on the head of the striker 9 produces a rupture of the membrane 5.

Предмет изобретени Subject invention
Приспособление дл тарировани безынерционных манометров, отличающеес тем, что оно выполнено в виде камеры, снабженной манометром дл измерени давлени и герметически отделенной от внутреннего объема тарируемого манометра мембраной, разрываемой дл передачи импульса давлени тарируемому манометру под действием давлени в камере или посредством ударника, снабженного пружиной и помещенного в станке камеры против разрываемой мембраны.A device for calibrating pressure-free manometers, characterized in that it is made in the form of a chamber equipped with a manometer for measuring pressure and sealed off from the internal volume of the manometer to be calibrated with a membrane that is broken to transmit a pressure pulse to the calibrated manometer under pressure of the chamber or through a drummer equipped with a spring and placed in the machine chamber against ruptured membrane.
