Description

Известны устройства дл  измерени  скорости движени  жидкости в трубах путем замера рассто ний между нагревателем и точками одинаковой телшературы на поверхности трубы по направлению потока и против него.Devices are known for measuring the velocity of fluid in pipes by measuring the distance between a heater and points of the same telesurature on the surface of the pipe in the direction of flow and against it.

В предлагаемом устройстве, с целью измерени  скорости жидкости Б закрытых трубах, нагреватель, соприкасающийс  с поверхностью трубы, скользит по П-образному стержню, па концах которого расположены последовательно включенные термопары.In the proposed device, in order to measure the velocity of liquid B in closed pipes, a heater in contact with the surface of the pipe slides over a U-shaped rod, the series-connected thermocouples are located at its ends.

На чертелче схематически изображено предлагаемое устройство дл  измерени  скорости движени  жидкост в трубах.The schemathe schematically shows the proposed device for measuring the velocity of the fluid in the pipes.

На поверхность трубы /, внутри которой протекает жидкость, нак .чадьгваетс  предлагаемое устройство.On the surface of the pipe /, within which the liquid flows, the device proposed is located.

По П-образпому стержню 2 с нанесенными на нем масплтабпыми делени ми скользит цагревате ть 6, укрепленный в держателе 7, внутри которого имеетс  термоизол ци  8 и прижимна  пружина 9. Ручка 10 держател  служит дл  переноса устройства и дает возможность прижимать нагреватель 6 и термопары 3 к стенке трубы, в которой измер етс  скорость протекаемой жидкости.On the U-shaped rod 2 with the masked divisions applied on it, the slide 6 is fixed, fixed in the holder 7, inside which there is thermal insulation 8 and pressing spring 9. The holder handle 10 serves to transfer the device and makes it possible to press the heater 6 and thermocouple 3 to the wall of the pipe in which the velocity of the flowing fluid is measured.

Внутри П-образного стержн  2 проложены провода от термопар 3 к клемме 5, к которой присоедин етс  чувствительный гальванометр.Inside the U-shaped rod 2, wires are laid from thermocouples 3 to terminal 5, to which a sensitive galvanometer is connected.

Дл  лучшего прилегани  термопар 3 к поверхности трубы / они снабжены пружинами 4.For better fit thermocouples 3 to the surface of the pipe / they are equipped with springs 4.

Измерение скорости движени  жидкости в трубе предлагаемым устройством производ т следующим образом.The measurement of the velocity of the fluid in the pipe by the proposed device is carried out as follows.

Нагреватель, питаемый электрическим током через контрольный ваттметр (на чертеже не показан), прижимают к стенке трубы и передвигают П-образнь Й стержень 2 в держателе 7 до тех пор, пока гальвансметр , присоединенный к клемме 5, не покажет нуль. После этого засекают рассто ние между нагревателем и термопарами, а затем по тарировочпой кривой определ ют скорость протекаемой жидкости.The heater, powered by an electric current through the control wattmeter (not shown), is pressed against the pipe wall and the U-shaped rod 2 is moved in the holder 7 until the galvanmeter connected to terminal 5 shows zero. After that, the distance between the heater and thermocouples is recorded, and then the velocity of the leaked fluid is determined by the calibration curve.

Предмет изобретени Subject invention

J/стройство дл  измерени  скорости движени  жидкости в трубах по замеру рассто ний между нагревателем и точками одинаковой температуры на поверхности трубы по направлению потока и против него, отличающеес  тем, что, с целью измерени  скорости жидкости в закрытых трубах, нагреватель, соприкасающийс  с поверхностью трубы , скользит по П-образному стержню, на концах которого расположены последовательно включенные термопары.J / A device for measuring the velocity of the fluid in the pipes by measuring the distance between the heater and points of the same temperature on the pipe surface in and against the flow direction, characterized in that, in order to measure the velocity of the liquid in closed pipes, the heater in contact with the pipe surface , slides on the U-shaped rod, at the ends of which there are series-connected thermocouples.
