最高のメタルシールが完成する。 Figure 1 shows the front view of the butterfly type water control valve.
The circular valve body A fitted inside the circular valve body B is the valve stem 1.
It is pivoted to valve box B. The outer periphery of the valve body A faces a seat surface 2 provided on the valve body B, and a metal seal is formed by abutment between the two. The valve body A is the second
The elastic member 4 is inserted into the concave groove 9 as shown in the figure.
The elastic member 4 is fitted with a metal valve seat 3 having a U-shaped cross section and having a core body and a strong thin metal plate attached to the outer peripheral surface thereof, and is in pressure contact with the groove bottom surface 10.
is always in a state of expanding outward due to its core and the elasticity of the thin metal plate with a U-shaped cross section attached to its outer circumferential surface. In addition to this, by screwing the mounting screw 6 into the screw hole 7 of the annular retaining plate 5, the valve body valve seat 3 is further extended toward the valve body B. The best metal seal is achieved by being in close contact with the seat surface 2.

The valve body valve seat 3, on which the elastic member 4 is attached, is fitted into the first notch A', and the elastic member 4 is pressed into close contact with the groove bottom surface 10. The holding plate 5 is fitted into the 2-notch A″. After that,
The holding plate 5 is fixed to the valve body A with mounting screws 6 through the screw holes 7 of the valve body A and the mounting holes 8 of the holding plate 5.

は巾広に製造されたものゝ場合を示している。 Here, the presser plate 5 shown in FIG. 3 has different shapes on its front and back surfaces, with a cutout surface 5'' of the presser plate having a notch on one side of the distal end, and a presser plate flat surface 5' on the other side. The size (width) of the concave groove 9 will differ depending on whether the presser plate 5 is attached to the front or the back.In other words, the core portion of the valve body valve seat 3 to be attached to this is formed. The elastic member 4 used is made of a material with extremely high elasticity, and the thin metal plate with a U-shaped cross section attached to the outer circumferential surface is also extremely elastic, so when manufacturing the valve body valve seat, the width is narrowed. Figure 3 A and B are relatively narrow, while Figure 3 C is wide. There is.

Apply the valve body to the notch while pressing the valve seat 3.
Attach the presser plate by adjusting it with the mounting screw 6 so that it fits into the presser plate 5. ' By attaching one of them to the front (or back), the width of the concave groove 9 can be changed, and the installation can be adjusted according to the size of the valve body valve seat 3, and the mounting screw 6 can be moved forward or backward. Even if there is a problem, the installation adjustment can be further compensated for.

ては極めて実用性に富む発明である。 Even if conventional valve seats perform well in tests at manufacturing sites such as factories in terms of water-stopping properties, they can easily deteriorate due to vibrations during transport to the piping construction site or stress during piping construction. However, with the present invention, it is possible to easily adjust the sealing condition to the optimum condition not only during manufacturing at a factory but also during installation work in a remote location. This is an extremely practical invention for this type of water control valve.
