加工していた。In each of the above-mentioned conventional valves 10, a solid steel bar material is formed into an external shape by upset press processing or extrusion press processing, and then the end surface of the valve head portion 1 (the one shown in FIG. 2 (-)) or the valve stem is A hole 3 was machined from the end surface of the portion 2 (as shown in FIG. 2(b)).
しかしながら上記従来の製造方法は、孔３の加工を必要
とするため弁の製造コストが高くなり、また孔３の偏心
、曲がり等により弁の製造′誤差が出易く生産性が悪い
という問題点がある。However, the above-mentioned conventional manufacturing method has the problem that the manufacturing cost of the valve is high because the hole 3 needs to be machined, and the manufacturing error of the valve is likely to occur due to eccentricity or bending of the hole 3, resulting in poor productivity. be.
本発明は上記に鑑みなされたもので、弁の製造工程を短
縮するとともに弁の精度を向上せしめ、低コストで量産
性の優れた弁の製造方法を提供することを目的とする。The present invention was made in view of the above, and an object of the present invention is to shorten the valve manufacturing process, improve valve precision, and provide a method for manufacturing a valve that is low cost and excellent in mass production.
〔問題点を解決するための手段、作用〕本発明は上記問
題点を解決するため、弁軸中空部をパイプにて製作し、
該中空部の両端にこれとは別個に製作した弁傘部及び弁
軸端部を溶接等により固着するようにしたことを特徴と
している。弁軸中空部をパイプで構成したので製造が簡
単であり、また精度も良く低コストかつ高品質の弁を提
供できる。[Means and effects for solving the problems] In order to solve the above problems, the present invention manufactures the hollow part of the valve shaft with a pipe,
It is characterized in that a separately manufactured valve head portion and valve stem end portion are fixed to both ends of the hollow portion by welding or the like. Since the hollow part of the valve shaft is made of a pipe, manufacturing is easy, and a valve with good precision and low cost and high quality can be provided.
以下第１図を参照して本発明の１実施例につき説明する
と、図において２０は弁、２１は該弁の弁傘部、２２は
パイプから成る弁軸中空部、２２ ａは孔、２３は弁軸
軸端部である。Hereinafter, one embodiment of the present invention will be described with reference to FIG. 1. In the figure, 20 is a valve, 21 is a valve head portion of the valve, 22 is a hollow portion of a valve shaft made of a pipe, 22 a is a hole, and 23 is a This is the end of the valve shaft.
上記構成を具えた弁の製造方法につき説明する。A method of manufacturing a valve having the above configuration will be explained.
先ず耐熱性、耐摩耗性大なる材料からなる弁傘部２１及
び耐摩耗性大なる材料からなる弁軸軸端部２３を鍛造に
て成形するとともに耐摩耗性の大なる材料からなるパイ
プの両端を所要長さに切断して弁軸中空部２２を成形す
る。First, the valve head part 21 made of a material with high heat resistance and wear resistance, and the valve shaft end part 23 made of a material with high wear resistance are formed by forging, and both ends of the pipe are made of a material with high wear resistance. The valve shaft hollow portion 22 is formed by cutting the valve shaft into a required length.
次いで弁軸中空部２２の両端に弁傘部２１及び弁軸軸端
部２３を電子ビーム溶接、摩擦圧接、レーザー溶接等に

有する中空形の弁を完成する。Next, the valve head part 21 and the valve shaft end part 23 are fixed to both ends of the valve shaft hollow part 22 by electron beam welding, friction welding, laser welding, etc., and then the outer surface is machined to form a hollow shape having a hole 22a. Complete the valve.
〔発明の効果〕
本発明は以上のように構成されており、本発明方法によ
れば、
（１） 孔あけ加工が不要となシ、弁の加工工数を低
減することができる。[Effects of the Invention] The present invention is configured as described above, and according to the method of the present invention, (1) Hole drilling is not required, and the number of man-hours for manufacturing the valve can be reduced.
（２）弁傘部、弁軸中空部、弁軸軸端部を別個の材料で
構成できるので材料特性を生かすことができ、耐食性、
耐熱性、耐摩耗性等の優れた材料を選択することができ
、材料コストの低減が図れ、中空形きのこ状弁をより低
コストかつ高品質とすることができる。(2) Since the valve head part, the valve stem hollow part, and the valve stem end part can be made of separate materials, the material properties can be utilized, and corrosion resistance and
Materials with excellent heat resistance, wear resistance, etc. can be selected, material costs can be reduced, and the hollow mushroom-shaped valve can be manufactured at lower cost and with higher quality.
