In addition, the pressure sensor itself may malfunction, and in particular, if the pressure sensor malfunctions and does not respond to pipe pressure even though it seems to be detecting normal pressure, it is impossible to detect an abnormality in the pressure sensor. There was a fear that the reliability of the equipment could not be guaranteed because normal equipment inspection could not be performed.
本考案は、このような従来の問題点に鑑みてな

まず構成を説明すると、１は消火ヘツドに消火
用水を供給する配管であり、配管１に三方継手２
を介して圧力センサ用の分岐管３を分岐接続し、
分岐管３の端部に三方電磁弁４を接続している。
三方電磁弁４の一方の切換側には管内圧力を検出

位置には排水管６が接続される。 First, to explain the configuration, 1 is a pipe that supplies fire extinguishing water to the fire extinguishing head, and a three-way joint 2 is connected to the pipe 1.
A branch pipe 3 for the pressure sensor is branched and connected through the
A three-way solenoid valve 4 is connected to the end of the branch pipe 3.
A pressure sensor 5 for detecting the pressure inside the pipe is connected to one switching side of the three-way solenoid valve 4, and a drain pipe 6 is connected to the other switching position.

６に開放させるように切換わる。尚、三方電磁弁
４のオン・オフ操作は中央監視室に設けた点検ス
イツチの操作で遠隔的に行なわれる。 The three-way solenoid valve 4 is in the first switching position when not energized and applies the pressure inside the pipe 1 from the branch pipe 3 to the pressure sensor 5. On the other hand, when the three-way solenoid valve 4 is energized, it switches to the second switching position, and in this second switching position, the path to the pressure sensor 5 through the branch pipe 3 is cut off, and the pressure sensor 5 is moved to the drain pipe 6. Switched to open to The on/off operation of the three-way solenoid valve 4 is performed remotely by operating a check switch provided in the central monitoring room.
次に、第１図の実施例の作用を説明する。 Next, the operation of the embodiment shown in FIG. 1 will be explained.
まず、通常時にあつては三方電磁弁４に対する
通電が遮断されて三方電磁弁４は第１の切換位置
に切換わつており、排水管６への流路を遮断する

配管１の管内圧力を分岐管３及び三方電磁弁４を
介して圧力センサ５に加え、圧力センサ５の検出
信号により管内圧力を監視している。 First, under normal conditions, power to the three-way solenoid valve 4 is cut off and the three-way solenoid valve 4 is switched to the first switching position, blocking the flow path to the drain pipe 6 and connecting the branch pipe 3 and the pressure sensor. 5 to communicate with each other,
The pressure inside the pipe 1 is applied to the pressure sensor 5 via the branch pipe 3 and the three-way solenoid valve 4, and the pressure inside the pipe is monitored based on the detection signal of the pressure sensor 5.
次に、圧力センサ５を点検する場合には、遠隔

に落ちる。従つて、監視室に表示している圧力セ
ンサの値が零に下がれば、圧力低下に対し圧力セ
ンサ５が正常に作動することが確認できる。 Next, when inspecting the pressure sensor 5, the three-way solenoid valve 4 is energized by remote control. By this energization, the three-way solenoid valve 4 is switched to the second switching position in which the pressure sensor 5 is disconnected from the branch pipe 3 and the pressure sensor 5 is opened to the drain pipe 6. Therefore, the pressure inside the pipe that had been switched until now is now the same as that in the drain pipe 6.
When the pressure is removed, the pressure applied to the pressure sensor 5 drops to zero. Therefore, if the value of the pressure sensor displayed in the monitoring room drops to zero, it can be confirmed that the pressure sensor 5 operates normally in response to a pressure drop.
次に、再び三方電磁弁４に対する通電を遮断す

介して配管１の圧力が圧力センサ５に加わり、そ
の結果、圧力センサ５の検出圧力は再び元の所定
圧力を表示するようになる。 Next, when the power supply to the three-way solenoid valve 4 is cut off again, the communication to the drain pipe 6 is cut off, and the pressure in the pipe 1 is applied to the pressure sensor 5 via the branch pipe 3. As a result, the detected pressure of the pressure sensor 5 will again display the original predetermined pressure.
このように、三方電磁弁４に対する通電による

ならば、圧力センサ５が正常な動作状態にあるこ
とを確認できる。 In this way, if the zero point check of the pressure sensor by energizing the three-way solenoid valve 4 and the display of the pipe pressure when the pressure sensor is restored by cutting off the power to the three-way solenoid valve 4 after the zero point check are performed normally, then the pressure It can be confirmed that the sensor 5 is in a normal operating state.

の表示状態に戻る。 The operation of the embodiment shown in FIG. 2 is that under normal conditions, the solenoid valve 7 is open and the solenoid valve 8 is closed.
The pressure inside the pipe 1 is applied to the pressure sensor 5 . On the other hand, when inspecting the pressure sensor 5, the solenoid valve 7 is closed and the solenoid valve 8 is opened by remote control to cut off the supply of the pressure inside the pipe 1 to the pressure sensor 5, and at the same time drain the pressure sensor 5. By opening the pipe 6, the pressure applied to the pressure sensor 5 is reduced to zero, and if the detected pressure of the pressure sensor 5 at this time drops to zero, it can be confirmed that the pressure sensor 5 is operating normally. . Further, when the solenoid valve 7 is opened and the solenoid valve 8 is restored after the zero check, if the pressure sensor 5 is normal, the display returns to the original state of displaying the pipe pressure.
