Description

камере 5 и дроссельном устройстве 7 был посто нным, использу  при этом показани  манометров 3 и 6. Открытием дроссел  4 измен ют площадь его проходного сечени  таким образом, чтобы на каждой ступени повышени  давлени  перед образцами, указатель сравнивающего устройства асзвра- щалс  в нулевое положение.the chamber 5 and the throttle device 7 was constant, using the readings of pressure gauges 3 and 6. By opening the throttle 4, the area of its cross-section was changed so that at each step of increasing the pressure in front of the samples, the pointer of the comparator would return to the zero position.

Качество контролируемого образца оценивают по заранее обусловленной разнице площадей проходного сечени  дроссеФормула изобретени The quality of the controlled sample is evaluated according to a predetermined difference in the cross-sectional areas of the cross-section of Drosse.

УСТРОЙСТВО ДЛЯ КОНТРОЛЯ КАЧЕСТВА ПОРИСТЫХ МАТЕРИАЛОВ.содерж ащее камеру дл  контролируемого образца , вход которой соединен с источником сжатого воздуха и манометром, а выход - с каналом с дросселем, имеющим регулируемую и измер емую площадь проходного сечени , отличающийс  тем, что оно снабжено дополнительной камерой дл  эталонDEVICE FOR CONTROL OF QUALITY OF POROUS MATERIALS. Containing a chamber for a controlled sample, the inlet of which is connected to a source of compressed air and a manometer, and the outlet - to a channel with a throttle having an adjustable and measurable passage area, characterized in that it is equipped with an additional chamber for reference
