Description

本発明は、スプリンクラ消火設備に係り、より詳しくは、応力励起発光体や光励起発光体を利用して配水管やスプリンクラヘッド内の流体の動圧と静圧を表示して異常を事前に発見することができるスプリンクラ消火設備に関する。   The present invention relates to a sprinkler fire extinguishing facility, and more specifically, an abnormality is detected in advance by displaying the dynamic pressure and static pressure of a fluid in a water pipe or a sprinkler head using a stress excitation light emitter or a light excitation light emitter. It can relate to sprinkler fire extinguishing equipment.

従来は、天井の下からは、スプリンクラヘッドに水圧等の流体圧が正常にかかっているかどうかを十分に把握することができなかった。
例えば、従来のスプリンクラヘッド取付台においては、スプリンクラヘッドを配管に取付ける取付台の目視できる位置に、取付台の内外に出没自在となる水圧表示体を取り付け、この表示体を、水圧が掛かっていないときに取付台内に没入させ、加圧水の水圧を受けたときは取付台外に突出させるように形成したものである（例えば、特許文献１参照）。 Conventionally, from below the ceiling, it has not been possible to fully grasp whether or not fluid pressure such as water pressure is normally applied to the sprinkler head.
For example, in a conventional sprinkler head mounting base, a water pressure display body that can be moved in and out of the mounting base is attached at a position where the mounting base for mounting the sprinkler head to the pipe can be seen, and the water pressure is not applied to the display body. It is formed so as to be sometimes immersed in the mounting base and protrude outside the mounting base when subjected to the pressure of pressurized water (for example, see Patent Document 1).

その構造は、図３に示すように、一端が開口された有底円筒状で内部に第１の細管１１から水が流入するパイプ状をなし、開口部１３ａ側には雄ねじ（または雌ねじ）１３ｂが形成され、第１の細管１１の端部に螺合するようにしてある。 The first pressure-specific color sensor 13 is a stress-excited illuminant that emits light with stress energy, senses the dynamic pressure of water in the water pipe or sprinkler head 1, and emits light when the water stress changes.

The pressure change is indicated by the brightness change.
As shown in FIG. 4, the structure is a bottomed cylindrical shape with one end opened, and a pipe shape into which water flows from the second thin tube 12 into the inside, and a male screw (or female screw) 14b on the opening 14a side. Is formed and is screwed onto the end of the second capillary 12.
The material is made of ceramic powder.

これらの第１の圧力色別センサー１３及び第２の圧力色別センサー１４の各雄ねじ（または雌ねじ）１３ｂ、１４ｂを、第１の細管１１及び第２の細管１２の雌ねじまたは雄ねじに螺入してシーリングプレート６の下面に位置させ、流体の加圧状況を天井の下から目視し管理できるようにして、品質保証の向上を図る。   The male screws (or female screws) 13b and 14b of the first pressure color sensor 13 and the second pressure color sensor 14 are screwed into the female screws or male screws of the first thin tube 11 and the second thin tube 12, respectively. Therefore, it is positioned on the lower surface of the sealing plate 6 so that the pressurization state of the fluid can be observed and managed from under the ceiling to improve quality assurance.

上記のように構成した本実施の形態１の作用を説明する。配水管やスプリンクラーヘッド１に異常が生じた場合、例えば、漏水によりスプリンクラヘッド１内に動圧が生じた場合、その動圧は、第１の細管１１を通って第１の圧力色別センサー１３に伝達される。第１の圧力色別センサー１３内に充填された水に動圧が生じると、その応力変化がセンシングされ、第１の圧力色別センサー１３を構成する金属酸化物の粉体等の素材にエネルギーが付与され、このエネルギー値が光エネルギーに変換される。こうして、第１の圧力色別センサー１３が発光し、応力が大きいほどその輝度が増すので、その輝度の度合いによって応力変化を外部より検知することができる。   The operation of the first embodiment configured as described above will be described. When an abnormality occurs in the water distribution pipe or the sprinkler head 1, for example, when dynamic pressure is generated in the sprinkler head 1 due to water leakage, the dynamic pressure passes through the first narrow tube 11 and the first pressure color sensor 13. Is transmitted to. When dynamic pressure is generated in the water filled in the first pressure-color-specific sensor 13, the stress change is sensed, and energy is applied to a material such as a metal oxide powder constituting the first pressure-color-specific sensor 13. This energy value is converted into light energy. Thus, the first pressure color sensor 13 emits light, and the brightness increases as the stress increases. Therefore, the stress change can be detected from the outside depending on the degree of the brightness.

また、配水管やスプリンクラヘッド１内の静圧に異常が生じてある所定の圧力を超過または減少した場合、その静圧の異常は第２の細管１２を通って第２の圧力色別センサー１４に伝達される。第２の圧力色別センサー１４内に充填された水の静圧に変化が生じると、その静圧の変化がセンシングされ、第２の圧力色別センサー１４を構成する金属酸化物の粉体等の素材にエネルギーが付与され、このエネルギー値が光エネルギーに変換される。こうして、第２の圧力色別センサー１４が発光し、静圧が大きいほどその輝度が増すので、その輝度の度合いによって静圧変化を外部より検知することができる。なお、第２の圧力色別センサー１４は光によって励起するので、光が照射されていないときは光を照射後に検知する。   In addition, when the static pressure in the water distribution pipe or the sprinkler head 1 exceeds or decreases a predetermined pressure, the static pressure abnormality passes through the second thin tube 12 and the second pressure color sensor 14. Is transmitted to. When a change occurs in the static pressure of the water filled in the second pressure color sensor 14, the change in the static pressure is sensed, and the metal oxide powder constituting the second pressure color sensor 14 and the like. Energy is applied to the material, and this energy value is converted into light energy. Thus, the second pressure-specific color sensor 14 emits light, and the luminance increases as the static pressure increases. Therefore, a change in static pressure can be detected from the outside depending on the degree of the luminance. Since the second pressure-specific color sensor 14 is excited by light, it is detected after the light is irradiated when the light is not irradiated.

上記の構成では、スプリンクラヘッド１の接続部２の側面に第１の細管１１及び第２の細管１２を接続した場合を示したが、本体部３の側面に通水路５に連通して接続してもよく、また側面に限定せず、通水路５内に連通するものであればいかなる部分に接続してもよい。
また、上記の構成では流体として水を用いたが、液体であればこれに限定するものではなく、また、液体でなく気体であってもよく、流動体であればいかなるものであってもよい。 In the above configuration, the case where the first thin tube 11 and the second thin tube 12 are connected to the side surface of the connection portion 2 of the sprinkler head 1 is shown. Moreover, you may connect to any part, as long as it communicates in the water flow path 5, without being limited to a side surface.
In the above configuration, water is used as the fluid. However, the liquid is not limited to this as long as it is a liquid, and it may be a gas instead of a liquid, and any fluid may be used. .

本実施の形態１によれば、圧力色別センサー１３、１４は工場でスプリンクラヘッド１に一体に組み込まれ、現場では簡単に取り付ける構造にして、コストアップを低くするようにし、付加価値を付けたので、客先の満足度を得ることができる。また、目視により遠くからでも簡単に圧力管理ができ、施工管理やメンテ等も容易である。   According to the first embodiment, the pressure color-specific sensors 13 and 14 are integrated into the sprinkler head 1 at the factory, and can be easily installed on site to reduce the cost increase and add value. Therefore, customer satisfaction can be obtained. Moreover, pressure management can be easily performed from a distance by visual observation, and construction management, maintenance, and the like are easy.
