(57) [Summary] [Purpose] To provide a high-pressure gas regulator capable of preventing an accident when the pressure rises excessively. [Structure] A complete shutoff valve was provided in the fluid passage in series with the pressure control valve.
Description
【０００１】[0001]
本考案は高圧ガスの調整器に係り、二次圧力による事故を未然に阻止できる高 圧ガス調整器に関するものである。 The present invention relates to a high-pressure gas regulator, and more particularly to a high-pressure gas regulator capable of preventing accidents due to secondary pressure.
【０００２】[0002]
可燃ガス、毒性ガスの調整器は、調整弁が損傷し、二次圧力が過度に上昇した 時、安全弁等によってガスを外部に放出させると、安全上問題が生じるため、安 全弁は設置されていない。そのため、過度に圧力が上昇すると、二次圧力計が破 損したり、ホースを破裂させる事故が発生する。 The regulator for combustible gas and toxic gas has a safety valve installed because if the regulator valve is damaged and the secondary pressure rises excessively, releasing the gas to the outside with a safety valve, etc. will cause a safety problem. Not not. Therefore, if the pressure rises excessively, the secondary pressure gauge may break or the hose may burst.
【０００３】[0003]
本考案の課題は、過度に圧力が上昇したときの事故を確実に防止できる高圧ガ ス調整器を提供することにある。 An object of the present invention is to provide a high pressure gas regulator that can reliably prevent an accident when the pressure rises excessively.
【０００４】[0004]
本考案の手段は圧力調整弁と直列に異常高圧ガスの流れを止める閉止弁を設け たことである。 The means of the present invention is to provide a shut-off valve for stopping the flow of abnormally high pressure gas in series with the pressure regulating valve.
【０００５】[0005]
平常時は図１に示すように完全閉止弁１６は開いており、調整ガスは２次側に 流れる。調整ガスの圧力が異常に上昇したときは、完全閉止弁１６のばね１９は 押されて閉じ、ガスの流れを止める。 In normal times, the complete shutoff valve 16 is open as shown in FIG. 1, and the adjusted gas flows to the secondary side. When the pressure of the regulated gas rises abnormally, the spring 19 of the complete shutoff valve 16 is pushed and closed to stop the gas flow.

図の符号１１は調整器本体で一次圧力の導入管１２と、２次圧力送出管１３を 設けて本体１１内の通路１４と一次圧力導入管１２と２次圧力送出管１３に連絡 させ、通路１４中に圧力調整弁１５を介在させ、かつ完全閉止弁１６を設ける。 Reference numeral 11 in the drawing is a regulator main body, which is provided with a primary pressure introducing pipe 12 and a secondary pressure delivery pipe 13 and communicates with the passage 14 and the primary pressure introducing pipe 12 and the secondary pressure delivery pipe 13 in the main body 11. A pressure regulating valve 15 is interposed in the valve 14 and a complete shutoff valve 16 is provided.
【０００７】 圧力調整弁１５は弁体１５1にコイルばね１５2を作用させ、フィルター１７を 経て送られた高圧ガス圧力を調節して２次側に送る。完全閉止弁１６が調整した ガス圧力が所定の圧力よりも高くなったときに、その高い圧力により通路１４を 閉じるように構成されている。即ち、１６1は弁体で弁杆１６2は強いコイルばね １９を作用させた受板２０を備え、通路１４中の弁座２１に接離する。The pressure regulating valve 15 causes the coil spring 15 2 to act on the valve body 15 1 to regulate the pressure of the high pressure gas sent through the filter 17 and send it to the secondary side. When the gas pressure adjusted by the full shutoff valve 16 becomes higher than a predetermined pressure, the high pressure is configured to close the passage 14. That is, 16 1 is a valve element, and the valve rod 16 2 is provided with a receiving plate 20 on which a strong coil spring 19 is acted, and contacts a valve seat 21 in the passage 14.
【０００８】[0008]
本考案によれば、二次側圧力の異常昇圧時に高圧ガスは止まるので、外部に流 れる危険を確実に防止できる。 According to the present invention, the high-pressure gas stops when the secondary pressure is abnormally increased, so that the danger of flowing to the outside can be reliably prevented.
