Description of the Related Art As a device that must delay the transmission of a signal even when a device that emits the signal is activated, there is a water flow detection device installed in a sprinkler fire extinguishing facility. When a fire occurs and the fire extinguishing liquid flows in the pipes of the sprinkler fire extinguisher, the water flow detection device detects this flow and issues an electrical signal to sound an alarm or display the location of the fire. To do.

It has to be

電気的な信号を発するようになっていた。In general, in a flowing water detecting device, the main body is partitioned by a main valve body into a primary side chamber and a secondary side chamber, and a signal water take-out hole is formed in a valve seat of this partition. When a fire occurs, the main valve body of the water flow detection device is opened, and at the same time, the signal water outlet is also opened, and the fire extinguishing liquid flows into it. The fire-extinguishing liquid led out of the water flow detection device through the signal water extraction hole emits an electric signal by activating a switch installed via a delay timer such as an electric delay device or a chamber. It was

起動し、設定された圧力範囲を維持するようになってい

するものである。The phenomenon that the extinguishing liquid flows in the running water detection device during non-fire occurs as follows. In other words, if the extinguishing liquid in the secondary side pipe where the sprinkler head is attached leaks and the pressure drops, supplement the amount of the extinguishing liquid that has leaked and keep the pressure in the secondary side pipe at the set pressure. I have to. Usually, in such a case, the auxiliary pump having a small discharge amount is automatically started and the set pressure range is maintained without starting the fire extinguishing pump of the water source. This auxiliary pump automatically stops at a predetermined pressure.

延装置やチャンバー等の遅延タイマーである。In this way, even when the auxiliary pump is activated, the main valve body is pushed up by the extinguishing liquid having a high pressure in the flowing water detecting device, and the extinguishing liquid flows into the signal water outlet. However, if a fire extinguishing liquid that flows during non-fire is detected and an alarm is issued, it will always be a false alarm. Therefore, in the running water detection device, in such a case, the running water detection device does not detect the flowing extinguishing liquid. That is a delay timer such as an electrical delay device or a chamber.

The switch is activated by the signal water flowing in more than that.

ればならなという大変に手間のかかるものであった。By the way, in the conventional delay timer using a chamber, since the chamber itself is large, it is necessary to secure a place for mounting the chamber in the vicinity of the water flow detecting device, which is not so good in appearance. Not only that, but it also took a lot of time to lay the pipes when installing. Further, although the electrical delay device is smaller than the chamber, it has a problem that it is very expensive because it has a complicated structure and is easily broken. Furthermore, when installing a conventional delay timer that operates with signal water in the water flow detection device of the sprinkler fire extinguishing equipment, it was necessary to let the signal water flow out from the water flow detection device. Had to be drilled or a valve seat or valve body for closing the hole had to be attached. However, since the water flow detection device has a valve structure, internal processing is performed by inserting a hole punching machine from the upper and lower pipe connection parts, and in the narrow interior, a valve seat is used with a tool such as a wrench or spanner. It was very time-consuming to install the valve and valve body.

Therefore, when the installation place is secured, the installation is troublesome, and when it is attached to the flowing water detecting device, the inside of the flowing water detecting device is It is to provide a delay timer that does not require time-consuming internal processing.

By closing the valve seat 15, the extinguishing liquid in the secondary side chamber is prevented from flowing back to the primary side chamber. It is preventing. The main valve body 11 is fully opened when the head portion 16 hits a stopper 17 formed inside the water flow detection device. Further, the shaft 14 projects in a watertight state to the outside of the running water detection device 10, and the large diameter gear 18 is attached to the outside of the shaft.

電させることはない。In the sprinkler fire extinguishing equipment equipped with the water flow detection device, when the flow of the extinguishing liquid at the time of non-fire, that is, when the extinguishing liquid leaks from the secondary side pipe and the pressure of the secondary side pipe decreases, this is illustrated. Not detected The pressure sensor detects and activates the auxiliary pump near the water source to send the fire extinguishing liquid into the pipe.
Then, the fire extinguishing liquid flows into the secondary side chamber 13 from the primary side chamber 12 of the water flow detection device 10, so that the main valve body 11 is pushed open by the fire extinguishing liquid. At this time, when the flow rate of the fire extinguishing liquid passing through the flowing water detection device is small, the main valve body 11 is not fully opened but is in a half-opened state, and the delay timer attached to the small diameter gear 19 is not completely below the electrode chamber. Therefore, the conductive fluid in the electrodeless chamber hardly flows into the electrode chamber 3, and the electrodes are not energized.

ない。When the amount of the extinguishing liquid passing through the running water detection device is large even during non-fire, the main valve body 11 is fully opened, the delay timer 1 is reversed, the electrode chamber 3 is on the lower side, and the electrodeless chamber is 4 is on the upper side. Then, the conductive fluid 9 in the electrodeless chamber 4 flows into the electrode chamber 3 through the orifice 5 as shown in FIG. However, since the amount of the fire extinguishing liquid sent to the secondary side pipe is small, the operation of the auxiliary pump is short, and when the auxiliary pump is stopped, the main valve body 11 lowers by its own weight to close the valve seat 15. When the main valve body 11 is closed, the small diameter gear 19 linked to the large diameter gear 18 is in a normal state, that is, the delay timer 1 has the electrode chamber 3 on the upper side,
The electrodeless chamber 4 returns to the lower side. That is, even if the electrode chamber 3 becomes the lower side and the conductive fluid flows into the electrode chamber from the upper electrodeless chamber due to the operation of the auxiliary pump during non-fire, it takes a short time, so that the two The electrode chamber does not return to the upper side and emit a signal before the electrodes are energized.

するとともに、警報装置を鳴らして避難警告をする。When a fire occurs and a large amount of fire extinguishing liquid is sprayed from the sprinkler head attached to the secondary side pipe, the main pump of the water source is activated, and a large amount of the fire extinguishing liquid of the water source is continuously supplied. Therefore, the main valve body 11 of the flowing water detection device 10 remains open. At this time, the delay timer 1 attached to the small-diameter gear 19 has the electrode chamber 3 on the lower side and the electrodeless chamber 4 on the upper side for a long time, so that all the conductive fluid 9 in the electrodeless chamber 4 flows into the electrode chamber 3. Then, the electrodes 6 and 7 which are separated from each other are brought into contact with each other, and a current is applied between them to generate a signal. The electric signal emitted from here displays a fire scene on a control panel (not shown) and sounds an alarm device to give an evacuation warning.

むものでもある。As described above, since the delay timer of the present invention has a simple structure, not only the manufacturing cost is low, but also the delay timer of the present invention is installed in the water flow detection device of the sprinkler fire extinguishing equipment. In this case, since the signal water extraction hole which is difficult to process and the valve seat for it are not formed in the flowing water detecting device, the flowing water detecting device also has an economical effect that the flowing water detecting device becomes inexpensive. Is.
In addition, the delay timer of the present invention is provided with an orifice between the electrode chamber and the electrodeless chamber in the sealed tube, and the two electrodes are separately installed in the electrode chamber, and the amount of contact between the two electrodes is large. Since the conductive fluid is enclosed, if the electrode chamber is located on the upper side for a short time, it takes time to pass through the narrow orifice, and the conductive fluid does not energize between the two electrodes.
