It shows the process. A short cylindrical portion 9 is formed in a portion of the tank 5 where the valve body 7 is to be attached, allowing communication between the inside and outside of the tank 5. At the base of this short cylindrical portion 9 on the outer surface of the tank 5, an annular groove 1 is formed.
0 is formed, and an annular body 11 (the cross section is not limited to the circular shape shown in the figure) made of a conductive metal such as iron, aluminum, or copper is inserted into this groove 10. There is. On the other hand, the cylindrical valve body 7 with a built-in butterfly valve (not shown) is connected to the tank 5.
The tank is made of the same synthetic resin (for example, nylon 66G30), and the tank is melted when the valve body 7 and the tank 5 are joined, and the tank is Concave groove 10 on the outer wall surface
A melting section 13 is formed that flows into the interior. The sum of the volume of this melted part 13 and the volume of the ring body 11 is set to be slightly larger than the volume of the groove 10. However, in order to stably connect the tank 5 and the valve body 7, the diameter of the annular body 11 should be about half the width W of the groove 10, and the depth D of the groove 10 and the melted part 1 should be
The height H of the melted part 1 is approximately equal to the height H of the melted part 1.
3 is desirably formed to be slightly smaller than the width W of the groove 10 (for example, w=about 2/3W).

る。In addition, the inner diameter of the valve body 7 (usually about 20 m/m) is slightly smaller than the outer diameter of the short cylindrical portion 9 (for example, 0.1 to 0.2
m/m), so that when the valve body 7 is joined to the tank 5, the valve body 7 can be easily fitted onto the short cylindrical portion 9. In addition, 14 is the valve body 7
A high frequency induction coil for generating heat in the annular body 11 when joining the annular body 11 and the tank 5.
It is provided near this ring body 11 so as to surround it.

固化し、上記両面を接着する。 When joining the tank 5 and the valve body 7 configured as described above, as shown in FIG. Then, the valve body 7 is fitted onto the short cylindrical portion 9, and the lower end surface of the fused portion 13 at the lower end of the valve body 7 is brought into contact with the ring body 11.
Next, when the high-frequency induction coil 14 is energized, an induced current flows through the annular body 11 and the annular body 11 generates heat. Melt the inner world.
The resin eluted from the molten part 13 flows into the groove 10, mixes with the resin eluted from the inner surface of the groove 10, and after being cooled and solidified, the tank 5 and the valve body 7 are joined in a fluid-tight manner. Further, the excess resin (very small amount) that does not fit into the groove 10 enters between the lower surface of the flange portion 12 and the outer wall surface of the tank, where it cools and solidifies, thereby bonding the two surfaces.
