Description
камеру противодавлени 6. Измер емое давление и иротиводавление наход тс как частное от делени величины силы, уравновешивающей иоршень, на известное значение эффективной площади поршневой системы.backpressure chamber 6. The measured pressure and counterpressure are as a quotient of dividing the force that balances the piston by the known value of the effective area of the piston system.
Конструкци , показанна на фиг. 2, отличаетс от рассмотренной выше тем, что противодавление создаетс жидкостью, проникающей в камеру противодавлени 6 из средней части зазора поршневой системы. При этом значение величины противодавлени зависит от характера распределени измер емого давлени в зазоре.The structure shown in FIG. 2 differs from that discussed above in that the back pressure is created by a fluid that penetrates into the back pressure chamber 6 from the middle part of the gap of the piston system. The value of the backpressure depends on the distribution of the measured pressure in the gap.
В конструкции манометра, показанной на фиг. 3, измер емое давление и противодавление подаютс от отдельных источников. В этом случае при каждом измер емом давлении регулируют противодавление в широких пределах и таким образом выбирают оптимальные услови работы поршневого манометра . In the design of the gauge shown in FIG. 3, measured pressure and back pressure are supplied from separate sources. In this case, at each measured pressure, the back pressure is regulated over a wide range, and thus optimal conditions for the operation of the piston gauge are selected.
Предмет изобретени Subject invention
Поршневой манометр высокого давлени , содерлсащий поршень и цилиндр, часть наружной поверхности которого размещена в камере противодавлени , высота которой ограничена уплотнительными кольцами, отличающийс тем, что, с целью повышени точности и расширени диапазона измерени ,A high-pressure piston gauge containing a piston and a cylinder, part of the outer surface of which is placed in a backpressure chamber, the height of which is limited by sealing rings, characterized in that, in order to improve accuracy and extend the measuring range,
в нем одно из уплотнительных колец расположено в средней части длины зазора между поршнем и цилиндром.in it one of the sealing rings is located in the middle part of the length of the gap between the piston and the cylinder.
