本発明は蒸気の輸送管、蒸気使用機器に発生し
た復水を導出する復水管などの蒸気管を流れる復
水の量を測定する流量測定装置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a flow rate measuring device for measuring the amount of condensate flowing through steam pipes such as steam transport pipes and condensate pipes that lead out condensate generated in steam-using equipment. .

しながら、蒸気は圧力変動を受けると比容積が大
きく変化するので、その流量測定は極めて困難で
あつた。 Measuring the flow rate of steam flowing through steam pipes can determine the amount of steam consumed by steam-using equipment, providing data for improving the heating efficiency of steam-using equipment. However, since the specific volume of steam changes greatly when it is subjected to pressure fluctuations, it has been extremely difficult to measure its flow rate.
従来の技術
そこで、本出願人は圧力変化が生じないように

水の流量を求めるものである。Prior Art Therefore, the present applicant has developed a device that measures the flow rate of condensate without causing pressure changes. The principle is to erect a wall in the condensate flow path, connect the upstream space and downstream space of the wall above the wall, make a hole such as a circular hole or a vertical slit in the wall, and install the device. A valve means such as a steam trap for automatically discharging condensate is disposed downstream of the drain hole, and the liquid level in the upstream space of the drain wall is detected to determine the flow rate of the condensate passing through the drain hole.
この場合、セキ壁の上流空間と下流空間はセキ
壁の上方で連通しているので、また、下流側には
スチームトラツプ等の気体は逃さずに復水を自動
的に排出する弁が取り付けてあるから、セキ壁の
上流空間も下流空間も、上流空間の蒸気と同じ圧
力である。従つて、復水は再蒸発を伴わずにセキ
孔を通過する。 In this case, the upstream space and the downstream space of the wall are connected above the wall, so a valve such as a steam trap is installed on the downstream side to automatically discharge condensate without letting gas escape. Therefore, both the upstream and downstream spaces of the wall have the same pressure as the steam in the upstream space. Therefore, condensate passes through the drain hole without re-evaporation.
セキ壁の上流空間の液位とセキ孔を通過する流
量との間には所定の関係があるから、この関係を
予め求めておき、液位を測つて、セキ孔を通過す
る復水の流量を求める。 Since there is a predetermined relationship between the liquid level in the upstream space of the shedding wall and the flow rate passing through the shedding hole, this relationship is determined in advance, the liquid level is measured, and the flow rate of condensate passing through the shedding hole is determined. seek.
この復水の流量を蒸気使用機器で消費した蒸気
の量として把握する。 The flow rate of this condensate is understood as the amount of steam consumed by the steam-using equipment.

に測定できても、これは蒸気の消費量ではない。Problems to be Solved by the Present Invention In this case, since condensate passes through the drain hole without being re-evaporated, an accurate condensate flow rate can be determined. However, if a valve means such as a steam trap causes steam leakage, the amount of steam leakage cannot be measured, so even if the condensate flow rate can be measured accurately, this is not the amount of steam consumed. .

ことができる。 For measurement, first, open the on-off valve. If the valve means does not cause steam leakage, the inlet side, i.e. the measuring chamber, and the outlet side are at the same liquid level;
When a leak occurs, steam passes through the hole and flows to the outlet, causing the liquid level in the measuring chamber to drop below the outlet side. This drop in the liquid level is detected by the liquid level detection means, and the amount of steam leakage is calculated from the correlation with the flow rate passing through the through hole. Next, the on-off valve is closed, and as in the past, the water level on the upstream side of the sheath is detected by the liquid level detection means, and the flow rate of condensate is determined from the correlation with the flow rate passing through the sheath. . Therefore, if the valve means is not leaking, the flow rate of condensate is considered to be the steam consumption amount, and if it is leaking, the sum of the flow rate of condensate and the amount of steam leakage is the exact steam consumption amount. can be measured.

If the side is at the same liquid level but a leak occurs, the steam will flow through the through hole 28 to the outlet 18 and into the measuring chamber 2.
2 is lower than the outlet 18 side. As the liquid level decreases, the float 58 descends, and the actuating rod 64 is simultaneously displaced by the action of the magnets 62 and 66. The displacement of the actuating rod is then converted into an electrical signal by a potentiometer 52. In this way, the liquid level in the measurement chamber 22 is converted into an electrical signal and taken out. The amount of steam leakage is calculated from the correlation between this liquid level and the flow rate passing through the through hole 28.
