Description
При прохождении воздуха через приемник 1 в сечени х каналов 5, соответствующих расположению щелей 2, возникает разность давлений . Давлени отбираютс через щели 2, выравниваютс в камерах 3 и через патрубки 13 отвод тс к измерительному прибору. Измер ема разность давлений при этом находитс в линейной зависимости от расхода воздуха, проход щего через приемник 1.With the passage of air through the receiver 1 in the sections of the channels 5, corresponding to the location of the slots 2, a pressure difference occurs. Pressure is taken through the slots 2, equalized in the chambers 3 and through the nozzles 13 is diverted to the measuring device. The measured pressure difference is in this case linearly dependent on the flow rate of air passing through receiver 1.
Предмет изобретени Subject invention
Преобразователь расхода воздуха в перепад давлени , содержащий пневматический приемник , щели и камеры, расположенные наThe air flow rate to pressure drop converter comprising a pneumatic receiver, slots and chambers located on
участках ламинарного потока, отличающийс тем, что, с целью повышени точности регистрации расхода воздуха, как при нормальном, так и форсированном дыхании, пневматический приемник выполнен в виде двусторонней гребенки с илоскопараллельными каналами, односторонних гребенок с параллельными пластинами, установленными в плоскопараллельных каналах двусторонней гребенки, и регул тора положени односторонних гребенок, а камеры выполнены в виде цилиндрических каналов, на противоположных образующих которых расположен, щели.sections of laminar flow, characterized in that, in order to improve the accuracy of recording air flow, both during normal and forced breathing, the pneumatic receiver is made in the form of a double-sided comb with illo-parallel channels, single-sided combs with parallel plates installed in plane-parallel channels of a double-sided comb, and the regulator of the position of one-sided combs, and the chambers are made in the form of cylindrical channels, on the opposite forming of which there are gaps.
