2. Description of the Related Art Generally, in sprinkler fire extinguishing equipment, when a sprinkler head installed on a ceiling operates due to an abnormally high temperature of a fire and water flows out from the sprinkler head and water in a pipe flows, this is detected as running water. The device detects the alarm and gives an alarm. At the same time, the pump of the water source is started, and further, water is sent into the pipe to spray a large amount of water from the activated sprinkler head to extinguish fire.

However, the sprinkler head may sprinkle water even if a fire does not occur. This is because a so-called “explosion” occurs in which the disassembled part of the sprinkler head is destroyed by an external impact applied to the sprinkler head.When the accident occurs, the valve seat of the sprinkler head is opened and water is sprayed. Resulting in.

When a fire occurs, water is sprayed from the sprinkler head to extinguish the fire, but at the same time, expensive equipment such as computers and important documents placed in the spraying area are splashed with water. In order to protect a building from a fire, it is unavoidable that the water damage due to the water get wet, but it is not preferable to cause the sprinkler head to explode even though the fire has not occurred.

Therefore, recently, a pre-operation type fire extinguishing system in which water is not sprayed only by operating a sprinkler head has been adopted. This pre-operation type fire extinguishing equipment is equipped with fire detectors such as heat detectors and smoke detectors near the installation of the sprinkler head.The fire detector detects the occurrence of a fire and the sprinkler head detects an abnormal fire. This is a dual safety system in which the water source pump is activated for the first time to spray water after operating at high temperature.

In the pre-fire type fire extinguishing equipment, a running water detection device is provided in the middle of the pipe between the sprinkler head and the water source, and pressure is applied from the valve body of the running water detection device to the primary side, which is the water source side, to fill the water. The secondary side, which is closer to the sprinkler head than the valve body, is filled with pressurized air.

In order to extinguish a fire in this pre-operation type fire extinguishing equipment, first, a fire detector whose operating temperature is lower than that of the sprinkler head detects heat and smoke of the fire, and a signal from the fire detector opens the valve body of the running water detection device, and the primary side is opened. Prepare to extinguish the fire by pouring the water of the above into the secondary side. Then, after that, the sprinkler head whose operating temperature is higher than the temperature sensed by the fire detector is activated, so that water flowing from the sprinkler head to the secondary side is sprayed to extinguish the fire.

By the way, in the conventional pre-operation type fire extinguishing equipment, since the secondary side pipe is not filled with water, the fire detector detects the fire and the sprinkler head is activated by the heat of the fire. Even when preparing to extinguish the fire, it took time for the water to reach the sprinkler head from the water flow detection device, and the fire could spread during that time.

Therefore, it is conceivable to fill the secondary side with water even in the pre-operation type fire extinguishing equipment. However, if the sprinkler head is destroyed by an external impact, as described above, the equipment and important documents in the room will be filled with water. The secondary side could not be filled with water due to the problem of damage.

Further, in the conventional pre-operation type fire extinguishing equipment, the sprinkler head extinguishes the fire, and water continues to be sprinkled from the sprinkler head even after the fire is extinguished. There was also a problem that the water sprayed from the sprinkler head was transmitted downstairs, causing water damage downstairs.

According to the present invention, since the secondary side is filled with water, water is sprinkled from the sprinkler head immediately in the event of a fire, and even if the sprinkler head bursts, water is sprinkled from the sprinkler head. Moreover, it is to provide a fire extinguishing facility that can reduce the water loss by stopping the spraying from the sprinkler head after the fire is extinguished.
