Description

【0001】
【発明の属する技術分野】
本発明は、屋内に設置した消火栓のホースの劣化を点検する耐圧試験機に関するものである。
【0002】
【従来の技術】
屋内に設置した消火栓の中には、ホースを装備したタイプのものが知られており、従来より、ホースの経年劣化による水漏れの有無を定期的に点検することが行われている。
【0003】
従来の方法は、消化栓箱内に櫛の歯状に折り畳んで収容してある15m程度のホースを消火栓のバルブに繋いだまま引き出して、ホースの先端にキャップを取り付けて塞ぎ、その状態で消火栓のバルブを開いて水をホース内に充填して水圧をかけ、ホースの水漏れの有無を調べて耐圧を試験し、経年劣化を点検するものである。この方法は、広い場所を必要する難点がある。
【0004】
一方、消化栓箱内のホースをバルブから取り外し、バルブに接続された端末部耐圧試験機の封止管をホース端部内に装着し、ホース端部内に封止管と封止管先端の封止部材とによって閉塞された空間を形成して、この閉塞空間に水を充填して水圧をかける方法があるが、この方法は、ホース端部における接続金具の装着部のみしか調べられず、残りの大部分のホース本体部については試験できない欠点がある。またこの端末部耐圧試験機は大きく重いので、試験機を移動するのに車両を必要とし、作業性が悪い難点もある。
【0005】
【発明が解決しようとする課題】
したがって、本発明の課題は、上記従来の問題点に鑑み、広い場所を取らず、コンパクト・軽量で携帯することができ、作業性も良好な屋内消火栓ホースの点検用耐圧試験機を提供することである。
【0006】
【課題を解決するための手段】
上記課題を解決するために、本発明は、
屋内消火栓ホースの点検用耐圧試験機であって、
屋内消化栓のバルブと接続される接続金具を一端に有し、圧力計と空気抜き管とを途中に備えた中空管に、消火栓のホースの一端および他端をそれぞれ接続する接続金具を有した対の枝管を少なくとも1対設けたことを特徴とする。本発明によれば、前記中空管の他端を含む任意の箇所に、該中空管に水を加圧送入する送水ポンプを接続して装備させることができる。
【0007】
本発明では、屋内消火栓のバルブに試験機の中空管を接続し、その中空管に設けた1対の枝管にホースの両端を接続してホースを2つ折り状に展開し、ホースに消火栓からの水を充填して水圧をかけ、ホースの水漏れを調査し耐圧を試験することにより、ホースの劣化を点検するのに従来の略半分の長さの場所でよく、広い場所を要しない。また水圧計による消火栓の水圧の測定と、水漏れの目視調査によるホースの耐圧とを同時に試験することができる。試験機の基本構成も、圧力計と空気抜き管とを取り付けた中空管に1対の枝管を設けた簡便な構造なので、コンパクト・軽量であり、試験機を携帯することもでき、作業性もよい。さらに中空管に枝管を2対以上を設けることにより、2本以上のホースを同時に試験することができる。また中空管に水を加圧して送入する送水ポンプを装備させた場合には、消火栓の水圧が低下しているときなどにも対処して、ホースに必要な水圧を得て耐圧を試験することができる。
【0008】
【発明の実施の形態】
以下、本発明の一実施の形態を図面に基づき詳述する。図1は、本発明の屋内消火栓ホースの点検用耐圧試験機を示す平面図である。
【0009】
本実施の形態の耐圧試験機1は、図示しない消化栓箱内の消火栓のバルブと接続される接続金具3を一端に有し、途中に圧力計4と空気抜き管5とを設けた中空管2に1対の枝管14、16を設けた基本構造を有している。本実施の形態では、さらに中空管2の他端に送水ポンプ20を装備させている。中空管2の接続金具3は、ホースの一端の消火栓のバルブに接続する接続金具と同一のワンタッチ式のメス型の差し込み金具とされている。
【0010】
中空管2の接続金具3寄りの位置にはソケット6が直角に設けられ、該ソケット6に空気用カプラであるソケット8がニップル7で取り付けられている。圧力計4と空気抜き管5とはT字管9に取り付けられ、T字管9には空気用カプラであるプラグ11がニップル10で取り付けられている。このT字管9側のプラグ11を中空管2側のソケット8に押し込むことにより、圧力計4と空気抜き管5とが中空管2に対し、ソケット8およびプラグ9を介して回転可能かつ取り外し可能に設けられている。また空気抜き管5とT字管9との間には、空気抜き管5を開閉するニードルバルブ12が介挿されている。
【0011】
枝管14、16は、圧力計4および空気抜き管5の取付位置より下流側の中空管2の部分に間隔を開けて設けられ、中空管2の他端側に向けて所定の角度、本例では45度の傾斜で突出されている。この枝管14、16の先端には、消火栓のバルブから外したホース(なお、ホースをバルブに接続せずに、元々外した状態で消火栓箱に収容している場合には、そのホースをそのまま使用する)と接続するための1対の接続金具15、17が取り付けられており、このうちの例えば接続金具15は、ホースの一端に設けられた接続金具と接続するワンタッチ式の雄型の差し込み金具とされ(消火栓のバルブの接続部と同一)、他方の接続金具17は、ホースの他端に設けられた接続金具と接続するワンタッチ式のメス型の差し込み金具(中空管の接続金具と同一)とされている。
【0012】
中空管2の接続金具3とは反対側の他端にはレバー18aで操作される開閉バルブ18が取り付けられ、送水ポンプ20は送水ホース19により開閉バルブ18を介して中空管2の他端に接続されている。この送水ポンプ20は、水を充填した試験機1内の水圧が試験水圧に達しないときに、水を中空管2に送り込んで水圧を高めるように補助的に使用するためのもので、必ずしも必要ではない。本例では、送水ポンプ20に手動タイプのものを用いている。なお、送水ポンプ20は、中空管2の他端以外の任意の箇所に設けることができ、そのときは中空管2の他端は栓をして閉じておく。
【0013】
本実施の形態の耐圧試験機1を使用して屋内消火栓のホースを試験するには、図2に示すように、消火栓21のバルブ21aからホース22を外し、試験機1の中空管2を適当な支持台24でバルブ21aの高さに支持して、中空管2の接続金具3をバルブ21aの接続部に押し込んで連結し、消火栓22と中空管3とを接続する。また中空管2の枝管14先端の接続金具15にホース22の一端の接続金具22aを、枝管16先端の接続金具17にホース22の他端の接続金具22bをそれぞれ押し込んで接続し、枝管14、16にホース22の両端を連結して、ホース22を2つ折り状に展開する。
【0014】
ついで消火栓21のハンドル21bを回してバルブ21aを開き、消火栓21から水を中空管2内に送り込んで、水を中空管2、空気抜き管5、枝管14、16およびホース22まで充填し水圧をかける。ついで空気抜き管5のバルブ12を何回か開いて排水することにより、試験機1の中空管2を初めとする管内の空気およびホース22内の空気を抜く。圧力計4の指示が安定して空気が完全に抜けたことを確かめたら、消火栓21のバルブ21aを閉じる。空気抜き管5には、空気抜き時の水を適当な箇所に排水するために排水ホース23を取り付けておく。
【0015】
上記のようにして、空気を抜いてホース22に水圧をかけたら、その状態でホース22に水漏れの箇所があるか否かを目視で調べ、また圧力計4が示す水圧に変動(減少)があるか否かを調べる。これにより、ホース22の経年劣化による耐圧を試験でき、また消火栓21の水圧も測定できる。
【0016】
上記において、空気が抜けて圧力計4の指示が安定したにもかかわらず、消火栓21の水圧が低下していて、指示する水圧が試験水圧の下限、例えば20気圧に満たない場合がある。そのときは、レバー18aによりバルブ18を開き、図示しない水道栓につないだ送水ポンプ20のハンドル20aを手で持って押し込んで、送水ポンプ19により水道栓からの水を加圧して中空管2に送入する。これにより圧力計4の指示が試験水圧に達したら、バルブ18を閉めて、上記と同様にホース22の水漏れを調査し耐圧を試験すればよい。
【0017】
本実施の形態の耐圧試験機1では、以上のように、屋内消火栓21のバブル21aに接続された中空管2の1対の枝管14、16に、消火栓のホース22の両端を接続してホース22を2つ折り状に展開し、そのホース22に消火栓からの水を充填して水圧をかけ、ホース22の水漏れ箇所を調査し耐圧を試験するようにしたので、ホース22の劣化を点検するのに従来の略半分の長さの場所でよく、広い場所を要しない。また水圧計4による消火栓21の水圧の測定と、水漏れの目視調査によるホース22の耐圧とを同時に試験することができる。
【0018】
またその耐圧試験機1の基本構成も、圧力計4、空気抜き管5を取り付けた中空管2の途中に、ホース22の両端を接続する1対の枝管14、16を設けた簡便な構造であり、試験機1がコンパクト・軽量で携帯することもでき、作業性がよい。
【0019】
ちなみに、本試験機1の寸法の一例を示せば、中空管2の一端の接続金具3の外端面と他端の送水ホース19の取り付け部までの長さが約380mm、中空管2の中心から圧力計4の外端までの長さが約60mmである。また枝管14の接続金具15までの中心軸線における長さが約121mm、枝管16の接続金具17までの中心軸線における長さが約110mmである。接続金具3および17は呼び径40で外径が約77mm、接続金具15は呼び径40で外径が約43mmである。
【0020】
以上の実施の形態では、中空管にホースを接続する枝管を1対設けたが、2対以上を設けてもよく、そうすることにより2本以上のホースを同時に試験することが可能になる。また中空管に水を加圧して送入する送水ポンプは、必ずしも装備する必要がないが、装備させた場合には、消火栓の水圧が低下していても対処して、ホースに必要な水圧を得て耐圧試験を実施することができる。
【0021】
【発明の効果】
以上の説明から明らかなように、本発明の耐圧試験機によれば、屋内消火栓のホースの耐圧試験を広い場所を取らずに実施して、ホースの劣化を点検することができ、また試験機もコンパクト・軽量で携帯可能にでき、作業性も良好である。

By pushing the plug 11 on the T-tube 9 side into the socket 8 on the hollow tube 2 side, the pressure gauge 4 and the air vent tube 5 can rotate with respect to the hollow tube 2 via the socket 8 and the plug 9. It is provided detachably. A needle valve 12 for opening and closing the air vent tube 5 is interposed between the air vent tube 5 and the T-shaped tube 9.
[0011]
The branch pipes 14 and 16 are provided at intervals in a portion of the hollow pipe 2 downstream of the mounting position of the pressure gauge 4 and the air vent pipe 5 and have a predetermined angle toward the other end of the hollow pipe 2. In this example, the projection is made at an inclination of 45 degrees. The ends of the branch pipes 14 and 16 are provided with a hose removed from the valve of the fire hydrant (if the hose is not connected to the valve but is housed in the fire hydrant box in the originally removed state, the hose is left as it is. And a pair of connection fittings 15 and 17 for connection with the connection fitting provided at one end of the hose. The fitting 17 is the same as the fitting of the valve of the fire hydrant, and the other connecting fitting 17 is a one-touch female-type plug fitting connected to the connecting fitting provided at the other end of the hose. The same).
[0012]
An open / close valve 18 operated by a lever 18 a is attached to the other end of the hollow tube 2 opposite to the connection fitting 3, and a water supply pump 20 is connected to the other end of the hollow tube 2 via the open / close valve 18 by a water supply hose 19. Connected to the end. The water supply pump 20 is used for auxiliary use so as to send water into the hollow tube 2 to increase the water pressure when the water pressure in the tester 1 filled with water does not reach the test water pressure, and is not necessarily required. Not necessary. In this example, a water pump of a manual type is used. In addition, the water supply pump 20 can be provided at an arbitrary position other than the other end of the hollow tube 2, and in this case, the other end of the hollow tube 2 is closed with a stopper.
[0013]
To test the hose of an indoor fire hydrant using the pressure resistance tester 1 of the present embodiment, as shown in FIG. 2, remove the hose 22 from the valve 21a of the fire hydrant 21 and remove the hollow tube 2 of the tester 1 The connecting pipe 3 of the hollow pipe 2 is pushed into the connecting portion of the valve 21a and connected by supporting the fitting 3 of the hollow pipe 2 at the height of the valve 21a by an appropriate support stand 24, and the fire hydrant 22 and the hollow pipe 3 are connected. Also, the connection fitting 22a at one end of the hose 22 is pushed into the connection fitting 15 at the tip of the branch pipe 14 of the hollow pipe 2, and the connection fitting 22b at the other end of the hose 22 is pushed into the connection fitting 17 at the tip of the branch pipe 16, and connected.

The hose 22 is folded in two, and the hose 22 is filled with water from a fire hydrant and water pressure is applied. The hose 22 is inspected for leaks and tested for pressure resistance. A half-length area is sufficient for checking, and does not require a large area. In addition, it is possible to simultaneously test the measurement of the water pressure of the fire hydrant 21 by the water pressure gauge 4 and the pressure resistance of the hose 22 by visual inspection of water leakage.
[0018]
The basic structure of the pressure tester 1 is also a simple structure in which a pair of branch pipes 14 and 16 for connecting both ends of a hose 22 are provided in the middle of the hollow pipe 2 to which the pressure gauge 4 and the air vent pipe 5 are attached. In addition, the testing machine 1 is compact and lightweight, and can be carried, and workability is good.
[0019]
Incidentally, if an example of the dimensions of the test machine 1 is shown, the length from the outer end surface of the connection fitting 3 at one end of the hollow tube 2 to the attachment portion of the water supply hose 19 at the other end is about 380 mm, and the length of the hollow tube 2 is The length from the center to the outer end of the pressure gauge 4 is about 60 mm. The length of the branch pipe 14 at the center axis to the connection fitting 15 is about 121 mm, and the length of the branch pipe 16 at the center axis to the connection fitting 17 is about 110 mm. The connection fittings 3 and 17 have a nominal diameter of 40 and an outer diameter of about 77 mm, and the connection fitting 15 has a nominal diameter of 40 and an outer diameter of about 43 mm.
[0020]
In the above embodiment, one pair of branch pipes for connecting the hose to the hollow pipe is provided. However, two or more pairs may be provided, so that two or more hoses can be tested at the same time. Become. It is not always necessary to equip a water pump that pressurizes and feeds water into the hollow pipe.However, if it is, even if the water pressure of the fire hydrant is low, the water pressure required for the hose can be adjusted. And a pressure test can be performed.
