る流m測定装置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a flow meter 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. Regarding.

流□測定は極めて困テ[1であった。By measuring the flow rate of steam flowing through steam pipes, it is possible to determine the amount of steam consumed by steam-using equipment, and data for improving the heating efficiency of steam-using equipment can be obtained. However, since the specific volume of steam changes greatly when it is subjected to pressure fluctuations, it is extremely difficult to measure its flow [1].
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して復水
の流Rを測定する装置の開発を行ってきた。その原理は

する復水の流量を求めるものである。BACKGROUND OF THE INVENTION Therefore, the applicant has developed an apparatus for measuring the flow R of condensate without causing pressure changes. The principle is to place a side wall in the condensate flow path, connect the upstream space and downstream space of the wall with the upper part of the wall, and insert circular holes, vertical slits, etc. in the side wall. A pipe hole is opened, and a valve means such as a steam trap for automatically discharging condensate is placed on the downstream side of the device, and the liquid level in the upstream space of the pipe wall is detected to control the flow rate of condensate passing through the pipe hole. It is something to seek.

ップ等の気体は逃さずに復水を自動的に排出する弁か取
り付けであるから、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。従って、復水は再蒸発
を伴わずにセキ孔を通過する。In this case, since the upstream space and the downstream space of the side wall communicate above the side wall, there is also a valve on the downstream side that automatically discharges condensate without letting gas such as steam I/lap escape. Because it is attached, 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セとの間
には所定の関係があるから、この関係を予め求めておき
、液位を測って、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 passing through the shedding hole, this relationship is determined in advance, the liquid level is measured, and the condensate flowing through the shedding hole is measured. Find the flow rate.

量でない。*Problem to be solved by the invention In this case, the condensate passes through the drain hole without being re-evaporated, so it is possible to obtain an accurate condensate flow rate. However, if a valve means such as a steam trap causes steam leakage, the amount of steam leakage cannot be measured. Not.

の流量を演算するようにした、ものでおる。Means for solving the problem A casing is used to form a fluid inlet and an outlet, and a partition wall is provided inside the casing to form a measurement chamber on the inlet side and a drainage space on the outlet side. A through hole is formed above the opening position of the outlet of the partition wall to communicate the drainage space with the drain space below the partition wall, and an on-off valve that opens and closes the through hole is formed in the casing/! - Attach it through the heat, and before measurement, divide the side wall with 32 cm to separate the upper and downstream spaces, connect the upstream space and the downstream space above the C wall, and make circular holes and vertically long holes in the side wall. A drain hole such as a slit is opened, a valve means for automatically discharging water at the outlet is arranged, a means for detecting the liquid level in the upstream space is provided, and the liquid level detecting means detects the liquid when the on-off valve is opened. The amount of steam leaking through the opening is calculated from the opening, and the flow rate of condensate passing through the opening is calculated from the liquid level detected by the liquid level detecting means when the on-off valve is closed.

として正確に測定することかできる。If the valve means does not cause steam leakage, the liquid level will be the same on the inlet side, that is, the measuring chamber and the outlet side, but if leakage occurs,
The steam passes through the hole and flows to the outlet, causing the liquid level in the measurement chamber to drop toward the outlet. 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, close the on-off valve and proceed as before.
The water level on the downstream side of the lateral wall is detected by a liquid level detection means, and the flow rate of condensate is determined from the correlation with the flow rate passing through the lateral hole. Therefore, if there is no leakage (valve means), the flow rate of condensate is considered the steam consumption amount, and if there is a leakage, the sum of the flow rate of condensate and the amount of steam leakage is considered the steam consumption amount. Can be measured accurately.
