底合し、その嵌合面を鋼ロウ材している。<Prior Art> The valve component has a part in which two cylindrical bodies made of a light metal material are fitted together, and the fitting surface is fixed with one piece of copper.For example, an electromagnetic In the case of a valve, a plug made of a non-magnetic material such as stainless steel is fitted onto the sliding part of the spool that is axially moved by a solenoid, and its fitting surface is made of steel. Made of waxed wood.
この鋼ロウ材の方法は、プラグの外径にリング状の銅ロ

プラグをバルブ本体の内径に嵌合し、高温真空炉内にて
銅「Ｊつ材を溶融して嵌合面の隙間に滲透さゼている。This steel brazing method involves installing four parts into which a ring-shaped copper brazing material is inserted on the outer diameter of the plug, inserting the steel material into these four parts, fitting the plug into the inner diameter of the valve body, and placing it in a high-temperature vacuum furnace. The copper material is melted and seeped into the gap between the mating surfaces.
〈発明が解決しようとする問題点〉

出せない問題がある。<Problems to be Solved by the Invention> In the case of the above-mentioned conventional steel brazing filler metal, the stainless steel plug has a higher coefficient of thermal expansion than the iron valve body, so the mating surfaces do not come into close contact at high temperatures. Although the molten steel brazing material hardens in the recess, it does not flow into the gap between the mating surfaces, making it difficult to ensure copper brazing strength. In addition, in consideration of the coefficient of thermal expansion, the outer diameter of the plug or the inner diameter of the valve body should be made thicker in advance so that the copper brazing material will flow into the gap between the mating surfaces (this will cause play in the fit between the two). There is a problem that the concentricity between the valve body and plug 7 cannot be achieved.

隙間Ｇ２が形成される。Since the present invention has the above structure, the ring-shaped copper brazing material 43 is inserted into the insertion gap, and the plug 40 is press-fitted into the cylindrical fitting surface 41 of the valve body 10. In this press-fitting, the press-fitting portion 51 is press-fitted into the cylindrical fitting surface 41 of the bell body IO of the plug 40 with a tightening margin, so that the valve hole 11 and the plug 40 are maintained in the same fitted state. Then, a gap G2 is actively formed between the cylindrical fitting surface 41 and the second stepped portion 50.

われるのである。This is heated in a high-temperature vacuum furnace or the like to melt the copper brazing material 43. At this time, the plug 40 with a high coefficient of thermal expansion expands, but the small gap G2 is thermally expanded and maintains a sufficient gap, so the molten copper brazing material 43 is transferred to the tapered surface 45.
It flows into the minute gap G2 along the copper brazing area B from the tapered surface 45 to the second step 50, and the soldering process 46 is performed.

A first step part forming four parts, a tapered surface continuous with the first step part toward the other fitting surface, a second step part, and a press-fitting part are provided. By making the gap into which the material flows large in anticipation of thermal expansion, the press-fit portion ensures a consistent fit, and the brazing filler metal reliably flows into the minute gap and becomes brazed, increasing the brazing strength of the fit. It has an increasing effect.
