Abstract
Устройство для измерения статического давления в потоке жидкости или газа, содержащее шаровидный пористый насадок, диаметр которого dудовлетворяет соотношениюгде ν - кинематическая вязкость среды, м/с;K- коэффициент проницаемости материала насадка, м;m - коэффициент пористости материала насадка;V - максимально возможная скорость потока среды, м/с,полую сферическую камеру диаметром d=(0,19-0,22)d, выполненную внутри насадка по его диаметральной оси со смещением относительно центра, и диаметрально расположенную в насадке приемную трубку диаметром d=(0,05-0,10)d, конец которой размещен в полости сферической камеры со стороны большего расстояния ее центра от поверхности насадка, отличающееся тем, что, с целью повышения точности измерения за счет обеспечения возможности регулирования коэффициента статического давления, в нем центр полой сферической камеры расположен на расстоянии ξ от центра насадка, равномξ=(0,24-0,35)d,при этом часть приемной трубки, находящаяся внутри насадка, выполнена проницаемой, а внутрь приемной трубки дополнительно введена тонкостенная непроницаемая трубка с возможностью радиального перемещения ее по длине приемной трубки.Device for measuring static pressure in a stream of liquid or gas containing a spherical porous nozzle, the diameter of which satisfies the relation where ν is the kinematic viscosity of the medium, m / s; K is the permeability coefficient of the nozzle material, m; m is the porosity of the nozzle material; flow rate of the medium, m / s, a hollow spherical chamber with a diameter of d = (0,19-0,22) d, made inside the nozzle along its diametrical axis with an offset relative to the center, and diametrically located in the nozzle receiving tube diameter m d = (0.05-0.10) d, the end of which is placed in the cavity of the spherical chamber from the side of a larger distance of its center from the nozzle surface, characterized in that, in order to improve measurement accuracy by providing the ability to control the coefficient of static pressure, in it the center of the hollow spherical chamber is located at a distance ξ from the center of the nozzle equal to ξ = (0.24-0.35) d, while the part of the receiving tube inside the nozzle is made permeable, and a thin-walled impermeable tube is additionally inserted into the receiving tube is possible radial displacement of its length along the receiving tube.
