れがある。(Prior Art) There are few effective methods for detecting leaks in piping systems that transport liquids, whether it is done online or offline. At best during IM construction, it is difficult to detect it after operation begins. In the piping system of a sewage treatment system, if there is a leak in the pipes that process sludge underground, there is a risk that the sludge will seep into the ground and cause environmental pollution.

ある。(Another means to solve the problem) The present invention divides piping of appropriate length into gate valves, and when the length of the piping is short, gate valves are installed on the inlet and outlet sides. A leak detection branch valve is installed in each division of the divided piping, and the leak detection branch valve is always closed and is a leak detection device used only when detecting leaks.

を水で充満さける。(Example) Figures 1 and 2 (31, showing one section of the piping system are required. In Figure 2, the gate valve 2 is closed. As a result, the gate valve 2 is closed. The separated piping section is cut off from other piping sections.Then, the leak detection branch valve 3 is opened and water 4 is injected into the pipe of the partitioned piping section, thereby filling the pipe with water.

示を示す。When the pipe is filled with water, the injection of water 4 is stopped and the branch valve 3 for leakage detection is closed. Then, the pressure chamber 5 having the pressure gauge 6 is connected to the leak detection branch valve 3. A compressor 7 or a cylinder is connected to the pressure chamber 5, from which pressure is increased. When the pressure within the pressure chamber 5 reaches a predetermined value, the stop valve 8 is opened to maintain the pressure within the pressure chamber at a predetermined value. ” The engine and cylinders shall also be stopped or closed respectively. The branch valve 3 for leak detection is opened and the pressure inside the chamber 5 is applied to the water filling the pipe. As a result, the pressure of the pressure chamber 5 is applied to the entire inside of the pipe 1 which is closed by the gate valve 2. Since piping 1 is filled with water, if there is no leakage in piping 1 (
In other words, since the time for this leakage detection is short, if temperature correction is ignored, the product PV of the volume V of the gas pressure section including the volume of the pressure chamber 5 and the pressure P is constant. Therefore, if there is no leakage, the reading on the pressure gauge 6 will not change. If there is a leak in the piping 1, the PV will not be constant and the pressure P will drop, so the pressure gauge 6 will indicate a pressure lower than the initial pressure.
上記の方法は漏洩検査が終った後にも配管１に水が残っ

る配管区分内に充濯１さＵて行なうことになる。The above method is for cases where there is no problem even if water remains in the pipe 1 even after the leakage test is completed, but if there is no problem if water remains in the pipe 1, the pipe classification should be carried out to test for leaks on the transported object itself. I'll have to do some recharging within 1U.

なって配管区分の漏洩検出が行なえる。When the object is being transported by the pump 9 in Fig. 2, the gate valve 2 on the outlet side of the piping section where leakage detection is to be performed is first closed, and the object is transported by the pump 9 into the piping section. After the material to be transported is filled (1), the gate valve 2 on the pump 9 side of the piping section is closed. Thereafter, leakage detection in the piping section can be performed as described above.

如く漏洩検出用分岐弁３を配置することにより圧力チェ
ンバ５内の圧力は第１図の水平に設置された配管系と同
じ圧力で漏洩検出ができる。If the piping system is installed at an angle, by arranging the branch valve 3 for leak detection as shown in Figure 3, the pressure inside the pressure chamber 5 will be the same as in the horizontally installed piping system shown in Figure 1. Leakage can be detected by pressure.

い。By using the present invention, piping leakage can be detected for each piping section, so even if a leak is detected, it can be repaired for each piping section. In addition, in the case of underground piping systems, the need for excavation work for repairs is reduced, which is highly effective in saving labor. Although this is a simple detection method, the effectiveness of leak detection can be further enhanced by setting the pressure in the pressure chamber to a level slightly higher than the pressure normally used by the piping. In particular, the present invention, which performs off-line leakage detection, is well suited to sludge piping in sewerage systems, and the sludge treatment itself is often badged. Furthermore, since leakage inspection can be carried out for each piping section, if leakage inspection is carried out during intervals between sludge treatment operations, there will be less disruption to daily work.
