られている。In addition, a handle attachment part 7 into which a handle 7 is inserted is provided at the bottom of the housing 4, and a drain port 8 to which a drain hose 9 can be attached is provided at the bottom of the housing 4. An O-ring 11 is provided on the inner wall of the opening 10.
このＯリング１１はスプリンクラーヘッド１の側壁に密
着する。This O-ring 11 is in close contact with the side wall of the sprinkler head 1.
次に作用について述べると、点検装置の挿入口５内に高
温用の液体を充満し、該液体内にスプリンクラー１の下
部を挿入１．．／、感熱部６のヒータに電流を流してこ
れを加熱すると、スプリンクラーヘッドの感熱部３が加
熱され、スプリンクラーヘッドより水が散水され、この
水はハウジング４にた捷り、ホース９を介して外部に排
出され、点検が完了する。Next, to describe the operation, the insertion port 5 of the inspection device is filled with high temperature liquid, and the lower part of the sprinkler 1 is inserted into the liquid. ．． / When a current is applied to the heater of the heat sensitive part 6 to heat it, the heat sensitive part 3 of the sprinkler head is heated, water is sprinkled from the sprinkler head, and this water is diverted to the housing 4 and passed through the hose 9. It is discharged outside and inspection is completed.
な釦点検の際には、スプリンクラーヘッドの上流の給水
装置を閉じ、ヘッドに水圧がかかつている状態にしてか
けば、わずかな排水により、ヘッドの点検ができる。When inspecting a sprinkler button, close the water supply system upstream of the sprinkler head and apply water pressure to the head, allowing the head to be inspected with a small amount of drainage.
第２図は本発明の他の実施例を示すもので、挿入口５の
下部に小室１４を設け、この小室の底に通気孔１２を設
け、この小室１４内に石綿等に可燃物１３′を含浸せし
めて、これを燃焼せしめて、スプリンクラーヘッドを加
熱する。FIG. 2 shows another embodiment of the present invention, in which a small chamber 14 is provided at the bottom of the insertion port 5, a ventilation hole 12 is provided at the bottom of this small chamber, and flammable materials such as asbestos etc. The sprinkler head is heated by impregnating it with water and burning it.
その他の構造については第１図の場合と同様である。The other structures are the same as those shown in FIG.
第３図は本発明の他の実施例を示すもので、挿入口５の
底に通気孔１２を設け、挿入口に可燃物１３′を入れ、
これを燃焼する。FIG. 3 shows another embodiment of the present invention, in which a ventilation hole 12 is provided at the bottom of the insertion port 5, a combustible material 13' is inserted into the insertion port,
Burn this.
本発明は叙上のように、スプリンクラーヘッドを点検装
置の挿入口にさし込んで試験を行うため、点検中のヘッ
ドの散水により周囲にある設備及び商品等をぬらすこと
がなく、簡単に点検することができる。As described above, the present invention performs the test by inserting the sprinkler head into the insertion port of the inspection device, so the water spray from the head during inspection does not wet surrounding equipment and products, making inspection easy. can do.
又この点検装置は感熱部にバイメタル等を用いた再用型
スプリンクラーヘッドに於では特に効果的である。Furthermore, this inspection device is particularly effective for reusable sprinkler heads that use bimetal or the like for the heat-sensitive portion.
従来のスプリンクラーヘッドにあ・いては、点検するこ
とは、すなわち破壊させることであり、余り意味がなか
ったが、本発明によれば、破壊せしめることな〈、点検
を可能ならしめうるものである。With conventional sprinkler heads, inspecting them meant destroying them, and there was little point in doing so, but according to the present invention, it is possible to inspect them without causing destruction. .
