シールが完成する。Figure 1 shows a front view of a butterfly-type water control valve, in which a circular valve body fitted inside a circular valve body (B) is pivotally supported by a valve stem (1) to the valve body (B). . The valve body (the outer periphery of the aluminum body faces the seat surface (2) provided in the valve body), and a metal seal is formed by abutment between the two. The valve body (2) has an elastic member (4) in a concave groove (9) as shown in FIG.
A metal valve body valve seat (3) with a U-shaped cross section is fitted, which is made of a core body and a strong thin metal plate coated on its outer peripheral surface.
The elastic member (4), which is in pressure contact with the groove bottom surface (10), is always prevented from expanding outward due to the elasticity of its core portion and the thin metal plate with a U-shaped cross section attached to the outer peripheral surface. In particular, the valve body (B) has a tendency to not extend toward the seat surface (2) of the valve body (B), which faces and abuts against the valve seat (3). ), the valve body valve seat (3) is further attached to the valve body (
B) Seat surface (2) When K is brought in close contact with the seat surface, the best metal seal is completed.

The valve body valve seat (3) on which the elastic member (4) is attached is fitted into the first notch, and the elastic member (4) is pressed into close contact with the groove bottom (10), and then inserted into the second notch C from above. The holding plate (5) is fitted. After that, apply the screw hole C force of the valve body prisoner and the holding plate (
Attach the holding plate (5) with the mounting screw (6) through the mounting hole (8) of

用することも出来、非常に好都合である。Therefore, the presser plate (5) shown in Fig. 4 has different shapes on the front and back surfaces, with a cutout on the front side of the presser plate (1) and a presser plate flat surface (1) on the other side. 51.The size and width of the recessed groove (9) will differ depending on whether the holding plate (5) is attached to the front or the back. The elastic member (4) forming the core of the body valve seat (3) is made of a material with extremely high elasticity, and the thin metal plate with a U-shaped cross section attached to its outer peripheral surface is also made of a material with extremely high elasticity. Because it is highly elastic, when the valve body valve seat is manufactured, a middle one and a wide one are formed, so the ones shown in Figures 4 (a) and (b) are relatively middle and wide. Fourth
Figure (/→ indicates a case manufactured with a wide width. Also, replacing the front and back of the holding plate in this way is the installation of a valve body (3) with a different width. The pressing of the valve body valve seat (3) can also be used to change and adjust the force, which is very convenient.

調整変化させることが出来るのである。In the present invention, as described above, a fitting groove is formed on the tip side of the valve body, and the valve seat (3) of the valve body, which has extremely high elasticity, is fitted into the fitting groove, and the valve seat (3) of the valve body, which has extremely high elasticity, is fitted into the fitting groove. The holding plate is attached by applying the holding plate (5), pressing the valve body valve seat (3), and adjusting it with the mounting screw (6) so that it fits into the notch surface. When screwed lightly and shallowly, the valve body valve seat (3) is small and protrudes toward the valve seat (2) side on the valve body side, forming a relatively shallow metal seal, and when screwed deeply and strongly, the valve body The valve seat (3) is largely pushed out toward the valve seat side of the valve box, and as a result forms a metal seal that strongly and reliably abuts.In this way, in the case of the present invention, the threading condition of the mounting screw (6) This allows the state of the abutting metal seal to be adjusted and changed in any way.
