【考案の詳細な説明】
本考案はヒユーズカランを介してエアー抜きを行う際に
使用するキャップに関するものである。[Detailed Description of the Invention] The present invention relates to a cap used when air is removed through a fuse ring.
ゴム管の脱落、切断等の不測のガス漏れ事故が生じた際
に、ガスカラン内を通過するガス流量の増加を感知して
、規定以上の流量であれば自動的にガスの流れヲ遮断す
るように設定したヒユーズカランの場合には使用初期の
管内からのエアー抜きに際してヒユーズが作動してしｌ
い、その１１ではエアー抜きを行うことは出来ない。In the event of an unexpected gas leak, such as when a rubber tube falls off or is cut, the system senses the increase in the gas flow rate passing through the gas cylinder and automatically shuts off the gas flow if the flow rate exceeds the specified limit. If the fuse is set to
No, it is not possible to bleed air with #11.
そこで、従来は栓を半開きにして行っているが、この方
法であるとエアー抜きに時間がかかり、作業能率が低下
する不便があった。Conventionally, the stopper is left half-open, but this method takes time to bleed the air and is inconvenient, reducing work efficiency.
本考案は上記問題点に鑑みて提案されるもので、ホース
接続口にヒユーズが作動しない程度の最大流量を通過さ
せる孔をもったキャップを装着し、このキャップにより
ガスの流れに抵抗をつけて簡単に然も早くエアー抜きが
出来るように構成したものである。The present invention was proposed in view of the above problems.The hose connection port is equipped with a cap that has a hole that allows the maximum flow rate to pass through without causing the fuse to operate, and this cap provides resistance to the flow of gas. It is constructed so that air can be removed easily and quickly.
以下、上記本考案の一実施例を詳記する。Hereinafter, one embodiment of the present invention will be described in detail.
１はヒユーズカラン本体であってガス配管接続口２によ
ってガス配管末端に接続されガスの供給をうける。Reference numeral 1 denotes a fuse column main body, which is connected to the end of a gas pipe through a gas pipe connection port 2 to receive gas supply.
３がヒユーズであって、規定量地上のガス流が生じると
浮上して弁座４に密着し、ガス流を遮断するもので、ハ
ンドル５を回動じて閉子６′ｆ：閉じれば、ヒユーズ３
はガス圧を利用して作動前の位置に戻るように設計され
ている。Reference numeral 3 denotes a fuse, which floats up when a specified amount of gas flow on the ground occurs and comes into close contact with the valve seat 4, blocking the gas flow.When the handle 5 is rotated to close the closure 6'f, the fuse is closed. 3
is designed to use gas pressure to return to its pre-activation position.
７が装着孔８およびそれに続く流量調節孔９を端面に有
するキャップであって、ホース接続口１０に該装着孔８
ｆ：装着し、ヒユーズカラン本体１内を通過するガスの
流量をヒユーズ３が作動しない程度の最大流量に制限す
る。Reference numeral 7 denotes a cap having a mounting hole 8 and a flow rate adjustment hole 9 following it on the end face, and the mounting hole 8 is connected to the hose connection port 10.
f: Installed to limit the flow rate of gas passing through the fuse cylinder main body 1 to the maximum flow rate at which the fuse 3 does not operate.
以上の構成によって、本考案は次に述べる作用、効果を
有する。With the above configuration, the present invention has the following functions and effects.
前述の如くヒユーズカランは設定流量より過大なガス流
が生じた場合に作動して安全性を確保するものである。As mentioned above, the fuse callan is activated to ensure safety when a gas flow exceeding the set flow rate occurs.
したがってガス配管内からエアーを抜く時にヒユーズ３
が作動すると、エアーが抜けないという状態に陥いる。Therefore, when removing air from the gas piping, fuse 3
When activated, the air will not be able to escape.
そこでこの場合にヒユーズ３が作動しない程度の流量を
流すように設定すれば迅速かつ確実なエアー抜きが実施
できる。Therefore, in this case, if the flow rate is set to a level that does not cause the fuse 3 to operate, air can be removed quickly and reliably.
そこで、あらかじめガス供給口すなわちホース接続口１
０の開口部にかいて流量を規定するために、該ホース接
続口１０に第２図に示す装着孔８とそれに続く流量調整
孔９を端面に有するキャップＴを第１図の如く取り付け
、閉子６を全開にしてエアー抜きを行うのである。Therefore, in advance, the gas supply port, that is, the hose connection port 1
In order to regulate the flow rate through the opening of 0, a cap T having an attachment hole 8 shown in FIG. 2 and a flow rate adjustment hole 9 following it on the end face is attached to the hose connection port 10 as shown in FIG. 1, and then closed. Air is removed by fully opening the valve 6.
流量調整孔９の大きさはヒユーズ３を作動させない限り
任意であるが、ヒユーズ３の作動流量はヒユーズカラン
設計時に規定しであるので、その規定流量を越えない程
度の最大流れを生じせしめるような開口面積をもつ流量
調整孔９が最適である。The size of the flow rate adjustment hole 9 is arbitrary as long as the fuse 3 is not operated, but since the operating flow rate of the fuse 3 is specified at the time of fuse callan design, the size of the flow rate adjustment hole 9 is determined to produce a maximum flow that does not exceed the specified flow rate. A flow rate adjustment hole 9 having a large opening area is optimal.
以上の如く本考案によれば、あらかじめ規定した流量以
上流れないように設定した開口面積の流量調整孔９を有
するキャップ７をホース接続口１０に装着して、ヒユー
ズ３を作動させることなくヒユーズカラン配管後の配管
内のエアー抜きを簡便かつ迅速に行なえる効果がある。As described above, according to the present invention, the cap 7 having the flow rate adjustment hole 9 with the opening area set so that the flow does not exceed a predetermined flow rate is attached to the hose connection port 10, and the fuse can be operated without operating the fuse 3. This has the effect of allowing air to be removed easily and quickly from inside the piping after piping has been installed.
