【考案の詳細な説明】
［産業上の利用分野］
この考案は火災における消防、又は洗浄その他
に広く用いられるノズルに関するものである。[Detailed description of the invention] [Industrial application field] This invention relates to a nozzle that is widely used for fire fighting, cleaning, and other purposes.
更に詳しくは内管及び外管から成る二重管を形
成したノズルに関するものである。 More specifically, the present invention relates to a nozzle formed with a double tube consisting of an inner tube and an outer tube.
［従来の技術］
従来この種のノズルの先行技術としては実開昭
54−21999号公報が挙げられる。 [Prior art] The prior art for this type of nozzle was
No. 54-21999 is mentioned.
これは、図示は省略するが、ノズルの本体が内
筒及び外筒により二重管状に形成され、内通路及
び外通路が形成され、それに設けたバルブを操作
することにより、上記内通路又は外通路のいずれ
か一方から放水ができるようになつている。そし
て上記内通路により直射放水を、外通路により噴
霧放水がなされるようになつている。 Although not shown in the drawings, the main body of the nozzle is formed into a double tube shape by an inner cylinder and an outer cylinder, and an inner passage and an outer passage are formed. Water can be sprayed from either side of the passage. Direct water is sprayed through the inner passage, and water is sprayed through the outer passage.
［考案が解決しようとする課題］
しかし上記先行技術は次のような難点を有して
いる。[Problems to be solved by the invention] However, the above-mentioned prior art has the following difficulties.
それは、そのノズルに内通路又は外通路のいづ
れか一方を開放するためのバルブが形成されてい
るが、その両通路を一度に閉止するバルブが設け
られてないのである。 This is because the nozzle is provided with a valve for opening either the inner passage or the outer passage, but there is no valve for closing both passages at once.
このため、両方の通路を一度に閉止するバルブ
は、このノズルから離れた場所、例えば消防車等
に設けられるものと思われるが、それでは同ノズ
ルを操作する場合に不便である。同ノズルを閉止
するバルブも操作員の手許に設けられていること
が好ましい。又同ノズルに前記両通路を一度に開
止するバルブを別に設けると、重量がほぼ倍増し
てしまい、火災の消防等の長時間取扱う場合に疲
労を来し、これも取扱いが困難である。 For this reason, a valve that closes both passages at once would probably be installed in a location away from this nozzle, such as in a fire engine, but this would be inconvenient when operating the same nozzle. Preferably, a valve for closing the nozzle is also provided at the operator's hand. Furthermore, if the same nozzle is provided with a separate valve to open and close both passages at once, the weight will almost double, causing fatigue when handling for long periods of time, such as when extinguishing a fire, and this is also difficult to handle.
又他の問題は、前記先行技術のバルブの弁体が
テーパーを有するため外通路に放水する場合、一
部の通路は狭く、一部の通路は広く開放され、放
水が偏つてしまうのである。このため外通路から
の噴霧は部分的に水量が偏つて形成されてしま
う。 Another problem is that because the valve body of the prior art valve has a taper, when water is discharged into the external passage, some passages are narrow and some passages are wide open, resulting in uneven water discharge. For this reason, the spray from the outer passage is formed with a partially uneven amount of water.
この考案はこのような問題を解決するためにな
されたもので、その目的は同一バルブで、即ちバ
ルブの重量を殆ど変えることなく、外通路及び内
通路をそれぞれ開放でき、しかも両通路を同一バ
ルブで一度に閉止することができ、しかも外通路
を開放する場合に、放水の偏りをなくすことので
きるノズルを提供することである。 This invention was made to solve this problem, and its purpose is to use the same valve, that is, to open both the outer passage and the inner passage without changing the weight of the valve, and to open both passages using the same valve. To provide a nozzle which can be closed at once and which can eliminate uneven water discharge when opening an external passage.
