プP′に対して銀鑞９で固定されている。 A conventional ball valve is as shown in Fig. 1, in which a forged brass body 1 is fixed to one copper pipe P with silver solder.
One sheet 3 is brought into contact with the inner periphery of the
The outer periphery of the ball valve 4 is brought into contact with the outer periphery of the ball valve 4. 5
shows the stem that rotates the ball valve. The other seat 6 is in contact with the outer periphery of the ball valve by a seat retainer 7 screwed into the main body 1. 8
is a holder which is also screwed into the main body 1 and fixed to the other pipe P' with silver solder 9.

いる。 That is, according to the present invention, a ring-shaped sheet receiver having a recess on the outer periphery is inserted into a metal pipe, and this sheet receiver is pressed from both sides using a pushing jig inserted from both sides of the pipe. By inserting a guide pin into the pipe at a regulated distance from the tip of one of the pushing jigs, and engaging the tip of this guide pin with the recess of one of the pushing jigs, the sheet receiver is moved. After positioning, the seat receiver is fixed by squeezing the pipe into the recess of the seat receiver.After removing the guide pin, fit one of the ring-shaped sheets into the seat receiver, and then insert the stem pipe into the guide pin position. Insert the ball valve from the inside and install it. Next, insert the ball valve so that it is in contact with one of the seats and its upper end engages with the lower end of the stem.
Next, the other similar ring-shaped seat is inserted so as to be in contact with the ball valve so as to face the above-mentioned seat, and the other seat holder that faces the above-mentioned seat holder that has a recess in which the packing is stored on the outer periphery is inserted. It is characterized in that it is inserted into a pipe so as to be in contact with the other sheet, and the pipe portion outside the other sheet holder is squeezed to support each of the above-mentioned elements.

支持される。 Next, each push jig screw part 16 and guide pin 18
is removed, and one ring-shaped sheet 2 of a predetermined size is removed.
6 is brought into close contact with the stepped portion 13 of the sheet receiver 11.
(FIG. 3) Furthermore, the stem 30 is inserted from inside the pipe into a collar 31 that has been attached to the pipe in advance. After that, the ball valve body 27 of a predetermined size is inserted into the groove 27 above the ball valve body 27.
Insert the stem so that the part a fits into the protrusion 30a at the lower end of the stem. When doing this, please use the ball valve body 2.
Since the center of the ball valve body 27 coincides with the center of the guide pin 18, the ball valve body 27 is reliably supported in a predetermined position.
