Description

Известные индикаторные трубки дл  ротаметров имеют канал конической формы, вследствие чего шкалы ротаметров, в которых применены такие трубки должны быть нелинейными, что затрудн ет тарировку и ведет к уменьшению точности измерений.The known indicator tubes for rotameters have a channel of conical shape, as a result of which the scales of rotameters in which such pipes are applied must be non-linear, which makes calibration difficult and leads to a decrease in measurement accuracy.

В описьиваемой ниже индикаторной трубке, в отличие -от известных, образуюшие канала трубки параллельны в одном диаметральном ее сечении, а .во втором, перпендикул рном ему сечении, наклонены к оси трубки под заданным углом. Такое выполнение индикаторной трубки позвол ет получать линейную градуировку шкалы.In the indicator tube described below, in contrast to known ones, the tubes forming the channel are parallel in one diametral section, and in the second, perpendicular section, they are inclined to the tube axis at a given angle. Such an embodiment of the indicator tube allows to obtain a linear graduation of the scale.

На фиг. 1 показан продольный разрез индикаторной трубки; на фиг. 2 - вид ее сбоку; на фиг. 3 - схема изменени  зазора между трубкой и поплавком, а на фиг. 4- схема изменени  площади проходного сечени  .ка.нала трубки.FIG. 1 shows a longitudinal section of the indicator tube; in fig. 2 is a side view of it; in fig. 3 is a diagram of the variation of the gap between the tube and the float, and FIG. 4 is a diagram of a change in the area of the flow area of the tube pipe.

Площадь зазора / между стенкой трубки и поплавком, как показано на фиг. 4, пропорциональна переменной ширине зазора х в данном поперечном сечении трубки и определ етс  ло формуле где а - посто нна  величина, пропорциональна  диаметру трубки.The area of the gap / between the tube wall and the float, as shown in FIG. 4 is proportional to the variable width of the gap x in a given cross section of the tube and is defined by the formula where a is a constant value proportional to the diameter of the tube.

Предмет изобретени Subject invention

Индикаторна  трубка дл  измерителей типа ротаметров, отличающа с  тем, что, с целью обеспечени  линейного увеличени  зазора при перемещении поплавка по каналу трубки, образующие ее канала параллельны в одном диаметральном сечении трубки, а во втором, ему перпендикул рном сечении, наклонены относительно оси трубки под задаиным углом.An indicator tube for meters such as rotameters, characterized in that, in order to provide a linear increase in the gap when the float moves through the tube channel, the channels forming it are parallel in one diametrical cross section of the tube, and in the second, perpendicular cross section, are inclined relative to the tube axis given angle.
