【考案の詳細な説明】
本考案は、内筒先端および外筒先端が一対のス
パーク電極に構成されているスパーク着火式火口
に関する。[Detailed Description of the Invention] The present invention relates to a spark ignition type nozzle in which the tip of an inner cylinder and the tip of an outer cylinder are configured as a pair of spark electrodes.
本考案に係る火口は、ガス溶接用もガス切断用
も、又、手動操作式も自動操作式も対象とする。 The crater according to the present invention is applicable to both gas welding and gas cutting, and both manually operated and automatically operated types.
第１図は従来の一例を示す。１が内筒、２が外
筒で内外筒の先端がスパーク電極３，４となつて
いる。（溶接用火口であれば、内筒１に切断酸素
通路は不要である。）この従来例には次の問題が
ある。それは切断又は溶接作業に伴うスパツター
（飛散する溶けた金属粒）が火口先端部に付着し
内筒１と外筒２との間に架橋すると、この架橋部
５で短絡が生じ（絶縁性消失）、スパークが起き
なくなる。このような架橋現象すなわち着火不能
の発生率が高いというのがその問題である。 FIG. 1 shows a conventional example. 1 is an inner cylinder, 2 is an outer cylinder, and the ends of the inner and outer cylinders serve as spark electrodes 3 and 4. (If it is a welding nozzle, there is no need for a cutting oxygen passage in the inner cylinder 1.) This conventional example has the following problems. This is because spatter (spattered molten metal particles) from cutting or welding work adheres to the tip of the crater and creates a bridge between the inner tube 1 and the outer tube 2, causing a short circuit at the bridge 5 (loss of insulation). , the spark will no longer occur. The problem is that the incidence of such crosslinking phenomenon, that is, failure to ignite, is high.
本考案の目的は、その問題を解決することであ
る。 The purpose of this invention is to solve that problem.
本考案の要旨に係る構成は、
円筒先端部分と外筒先端部分のうち少なくとも
一方においてその部分の大部分が電気絶縁材で被
覆され、残りの僅少部分がそれのスパーク電極に
なつている、という構成である。 The configuration according to the gist of the present invention is that most of at least one of the cylindrical tip portion and the outer cylinder tip portion is covered with an electrically insulating material, and the remaining small portion serves as a spark electrode. It is the composition.
これの作用は次のとおりで、スパツターが火口
先端に付着する確率が従来と同じとしても、スパ
ーク電極において付着し架橋する確率は大幅に低
くなることである。たとえば僅少な電極部分が周
方向で占める角度が５゜であるとすれば、その架
橋確率は理論上5/360（＝1.39％）、３°であると
すれば、同じく0.83％である。電気絶縁材のとこ
ろでスパツターが付着し架橋してもこれは短絡を
生じないので、ガス噴出のことはともかくとして
スパークの点では支障とはならない。 The effect of this is as follows: even if the probability of spatter adhering to the tip of the crater is the same as before, the probability of adhesion and crosslinking at the spark electrode is significantly lowered. For example, if the angle occupied by a small electrode portion in the circumferential direction is 5°, the crosslinking probability is theoretically 5/360 (=1.39%), and if it is 3°, it is also 0.83%. Even if spatter adheres to and bridges the electrical insulating material, this will not cause a short circuit, so it will not be a problem in terms of sparks, apart from gas ejection.
このように本考案によれば、スパツターによる
短絡の確率を大幅に低減化し、着火性の向上を図
れる、という効果がある。 As described above, the present invention has the effect of significantly reducing the probability of short circuits due to sputtering and improving ignitability.
次に本考案の実施例を説明する。 Next, embodiments of the present invention will be described.
