つた。 The structure of a conventional top-shaped valve body is shown in FIGS. 1 and 2. The top-shaped valve body shown in FIG.
A screw shaft b is protruded from the gasket attachment surface of the screw shaft, and a top gasket c is fitted to the base end of the screw shaft, and a nut d is screwed onto the screw shaft b, and by tightening the nut d, the top gasket is removed. It is made by fixing c.
With this structure, after years of use, there was a risk that the nut d would loosen and the top seal c would fall off. Also the second
The top-shaped valve body shown in the figure has a dovetail-shaped recess f formed in the top holder e, and the top packing g is connected to the recess f.
However, the dovetail groove-like recess cannot be formed by forging and must be cut by cutting, which increases processing costs. When fitting into the recess f, the top packing g
The outer edge of the recess had to be elastically contracted so as to be able to restore its original shape to pass through the narrow entrance of the recess f.
For this reason, it is difficult to assemble and is not suitable for mass production.At the same time, when it is attached to a faucet, the diameter of the piece packing G that faces the valve seat surface H is small, so it is not suitable for mass production. As shown, when the tap is opened, the outer edge i of the top block obstructs the flow of water, reducing the area through which water can pass, resulting in a correspondingly smaller amount of water flowing.

である。 The present invention aims to solve the above-mentioned drawbacks, and includes a side wall whose inner circumferential surface is at least perpendicular to the periphery of the gasket attachment surface of the top stand, so that the shaft forming surface of the top stand expands toward the tip of the shaft. The side wall is formed into a tapered surface shape, and a disc-shaped top packing is fitted into a recess surrounded by the side wall, and then the top base is compressed to make the shaft forming surface planar. This is a method for manufacturing a top-shaped valve body that is tilted inward and formed into a dovetail groove shape.
以下に本発明の実施例を説明する。 Examples of the present invention will be described below.

積が確保される。 In the manufacturing process diagram using a press mold shown in FIG. 4, reference numeral 1 denotes a top support vertically supported by loosely fitting a shaft 4 into a vertical hole 3 of a lower mold 2, and a gasket of the top support 1. A side wall 6 that is perpendicular to both the inner and outer peripheral surfaces is integrally protruded from the peripheral edge of the mounting surface 5, and the shaft forming surface 7 of the top stand 1 is inclined at an angle α and is oriented toward the shaft tip. It is formed into a tapered surface shape that widens. Reference numeral 8 denotes a disk-shaped top packing whose outer diameter approximately matches the inner diameter of the side wall 6, and the top packing 8 is fitted into a recess surrounded by the side wall 6. Next, the spindle stand 1 is pressed between the lower die 2 and the upper die 9 from above and below to plastically deform the tapered shape of the shaft forming surface 7 into a planar shape as shown in FIG. As a result, the peripheral edge of the top stand 1 is lifted upward, causing the side wall 6 to tilt inward and the recess to form a dovetail groove, thereby firmly clamping and holding the top packing 8 from the periphery. FIG. 6 shows the state in which the top-shaped valve body manufactured in this manner is used. In this case, since the side wall 6 is inclined inward, a sufficient water flow area is ensured when the valve is opened.

点があるほか、第１図に示した従来の螺子止式に
用いられていた孔開のこまパツキンをそのまま使
用できる利点もある。 The top-shaped valve body shown in FIGS. 7 and 8 has a vertical center shaft 10 that is integrally provided in advance at the center of the gasket attachment surface of the top stand 1. In this case, the upper die 9 By pressing down the central shaft 10 with the screw, the top stand 1 is deformed and the top packing 8 is irremovably fitted. In this case, when the outer periphery of the top packing 8 is held, frictional force acts on the contact surface between the center hole of the top packing 8 and the central shaft 10, so that the top packing 8 is deformed and only the center part is stuck. In addition to being advantageous in that it can be prevented from coming loose from the attachment surface 5, there is also the advantage that the perforated piece packing used in the conventional screw fastening type shown in FIG. 1 can be used as is.

る。 As explained above with respect to the embodiments, according to the present invention, the top-shaped valve body can be easily manufactured by press working, so the production efficiency is high and it is suitable for mass production. It has the beneficial effect of being able to be used for a long period of time without damage, without any drawbacks such as concerns or small water-permeable area.
