For example, department stores, theaters, cinemas, high-rise office buildings,
Buildings such as high-rise hotels are obliged to install sprinkler fire extinguishing equipment.

している。In a sprinkler fire extinguishing system, when a fire occurs, a sprinkler head mounted on the ceiling operates due to an abnormally high temperature of the fire, and water is automatically sprayed to extinguish the fire. Therefore, the sprinkler fire extinguishing equipment has a very excellent effect of protecting the human life because it prevents the fire from becoming large and can extinguish the fire without the person's knowledge.

った。As described above, it is desired to install the sprinkler fire extinguishing equipment having excellent effects in a general house. However, since the sprinkler fire extinguishing equipment prescribed by the Fire Service Law is for large buildings as described above, its associated equipment In addition, a large-scale water source, a large pump for pumping the water from the water source, and a large-scale device such as a water flow detection device that notifies the flow of water in the pipe were required, and the equipment cost and installation work were very expensive.

らである。Therefore, the advent of a sprinkler fire extinguishing system for a house, which can be installed inexpensively by using tap water, has been desired. However, when tap water is used as a sprinkler fire extinguishing system for a house, there have been regulations under the Water Supply Act, and it has not been practically available so far. That is, according to the Water Supply Act, if there is a stagnation part of water in the middle of the pipe, it rots and becomes so-called "dead water", which is a sanitary problem.
【0006】しかしながら、前述の如くスプリンクラー

とから、水道法も緩和され、配管途中に死に水が発生し
ないようにすれば水道水を利用した住宅用スプリンクラ
ー消火設備が使用できるようになってきた。However, as described above, the sprinkler fire extinguishing equipment has a great effect on the initial fire extinguishing and the protection of human lives. Therefore, the tap water law was eased, and tap water was used if water was not generated in the middle of piping. Residential sprinkler fire extinguishing equipment has become available.

No. 263, No. 33561), and a tube for sucking out dead water in the attachment portion of the sprinkler head is installed in the joint (JP-A-3-231685, No. 2316).

料費と敷設費が高価となるという問題があった。By the way, the conventional measures against dying water are to install a water faucet at the tip of the fire extinguishing pipe so that the water flows through the pipe in one way when the water flows out from the water faucet. , This flow was designed to eliminate water from the fall pipe and the valve body of the sprinkler head. Therefore, the fire-extinguishing pipe connected to the water supply pipe must have a water tap installed at its tip, and a pipe having a detour from the ceiling to the place where the water tap was installed was necessary. However, when the location where the water tap is installed is far from the ceiling, there is a problem that piping for the detour becomes long and material cost and installation cost become expensive.

の狭い弁体部分まで流入していかなかったからである。Although the conventional measures against dying water have some effect, they cannot completely eliminate the dying water.
The reason for this is that even if guide vanes and strips are installed in the pipe, the flow force of the flowing water is not sufficient, and the flowing water falls and flows into the narrow valve body part of the sprinkler head attached to the tip of the pipe. Because I didn't go.

When the tap water is connected and the tap water flows out from the faucet, the tap water flows back and forth in the fire extinguishing pipe to return to the water feed pipe, and then the tap water flows out from the tap. It is a sprinkler fire extinguishing system for homes.

む。[Operation] Since a reciprocating passage is installed in the fire extinguishing pipe and water flowing in the water supplying pipe is made to flow in the reciprocating passage of the fire extinguishing pipe, it is not necessary to attach a water tap to the tip of the fire extinguishing pipe. . As a result, it is not necessary to provide a pipe around the tip of the fire extinguishing pipe to the water tap. Also, because water always flows in the outward path of the fire extinguishing pipe, the flow of water has momentum, and water enters into the valve body part of the sprinkler head.

部6方向に流動する。When the water tap 2 in the washroom is opened to allow water to flow out, the water sent from the water main (not shown) flows from the lower water pipe 1 to one of the branch cheese joints 3 as shown by the arrow. It flows into the lateral joint section 4. Branch cheese joint 3
Since there is a vertical bulkhead 7 in the inside, the water that has flowed in from one horizontal joint portion 4 does not flow out from the other horizontal joint portion 5, and the vertical horizontal wall 7 extends along the central vertical bulkhead 7. It flows in the direction of the joint portion 6.

なる。Since the water reaching the lower end of the long pipe 8 is a complete unidirectional flow, it has a force and flows into the valve body portion of the sprinkler head 18 attached to the long pipe 8. Therefore, water does not stay in the valve body portion of the sprinkler head, and new water always flows in.

After flowing into the valve body portion of the above, it flows in the return path 10 of the long tube 8 which is a falling tube. This water flows from the elbow joint 19 through the return path 10 of the long tube 8 which is a horizontal tube and the upper flow path of the head joint to the branch cheese joint 3 and the lateral joint portion 5 of the branch cheese joint 5. Flows into the water supply pipe 1 connected to. The water then flows out from the water tap 2 attached to the tip of the water pipe 1.

きる。As described above, in the sprinkler fire extinguishing system for a house of the present invention, tap water flows back and forth in the fire extinguishing pipe to which the sprinkler head is attached. Since it is not necessary to attach a water tap to the tip of the pipe, and as a result, unnecessary detour piping is not required, the number of piping materials is small and the construction cost is also low. Further, the pipe material used for the sprinkler fire extinguishing equipment for a house of the present invention has a reciprocating flow passage formed inside one pipe material, so that the flow of water can be urged and the sprinkler water is likely to stagnant.
