The through hole 13 that respectively has a step as shown in Figure 3, the outside of valve sleeve 10 becomes large-diameter portion 14, inboardly becomes minor diameter part 15, is formed with step surface 16 between large-diameter portion 14 and minor diameter part 15.Even under the situation that the insertion length to through hole 13 of connecting duct 11 is lacked, for this connecting duct 11 is fixed on valve sleeve 10 firmly, and make between the inner peripheral surface of large-diameter portion 14 of outer peripheral face that connecting duct 11 is installed and through hole 13 slit G across around ground impartial.
For this reason, make the minor diameter part 15 of the through hole 13 that has step roughly consistent, and large-diameter portion 14 is slightly larger than the outside dimension of connecting duct 11 with the internal diameter of connecting duct 11.Therefore, if connecting duct 11 is being carried out with respect to through hole 13 under the state of adjusting at the center, when engaging, between the inner peripheral surface of the outer peripheral face of this connecting duct 11 and large-diameter portion 14, be formed with circular slit G with step surface 16.Soldering is a heating and melting scolder 17, at this slit G infiltration solder flux, reduces temperature, thus, and at through hole 13 fixedly connected conduits 11.Because of slit G around approximate equality in the scope, so solder flux spread all over this slit G around.
Be provided with connecting duct 11a～11d of 4 on valve sleeve 10, installing simultaneously, use slide unit 20 shown in Figure 4.Slide unit 20 constitutes along rail plate (ス ラ ィ De ガ ィ De) 21 and is directed to, by cylinder 22 at the conduit assembly bench S1 of (the Group body Write む) connecting duct 11 of packing into carry out as the scolder 17 of grafting material coming and going between the warm table S2 of heating and melting and move.
The center adjustment becomes towards the holding section of connecting duct 11a～11d 29a～29d with the end of bar 28a～28d, is formed with in its other end to carry knob (っ ま body) 30a～30d.The center adjustment is inserted the specific length part with the front end of holding section 29a, the 29b of bar 28a, 28b only with respect to connecting duct 11a, 11b.On the other hand, the center adjustment constitute the end of connecting duct 11c, 11d with holding section 29c, the 29d of bar 28c, 28d can be chimeric with specific length.Therefore, can make the center adjustment integrated with bar 28a～28d and connecting duct 11a～11d.Although connecting duct 11a～11d bending, slotting leading at the position of inserting hole 27a～27d is to become the position of the center adjustment of linearity with bar 28a～28d.And, because of inserting hole 27a～27d towards oblique below, so the adjustment of these centers with bar 28a～28d by its action of gravity, downward load is had an effect.
According to above situation, connecting duct 11a～11d is pressed in the direction that each step surface 16 with the through hole 13a～13d that has step connects.And, because of inserting hole 27a～27d has the length of regulation, so the direction of connecting duct 11a～11d when each step surface 16 with through hole 13a～13d connects fixed.Therefore, set with respect to the mode that the through hole 13a～13d that has step carries out centering with at this moment connecting duct 11a～11d.Thus, become between the inner peripheral surface of the large-diameter portion 14 of the outer peripheral face of whole connecting duct 11a～11d and through hole 13a～13d across around scope ground form the state of the slit G of approximate equality.
Be provided with high-frequency induction heating apparatus 40 at warm table S2.High-frequency induction heating apparatus 40 possesses coil 41, and this coil 41 is connected to not shown high frequency electric source.Coil 41 is installed in lift component 42, and lift component 42 can move up and down along guide rod 44 by lift drive mechanism 43.In the lifting position of lift component 42, the operation post 23 of valve sleeve 10 and connecting duct 11 is installed, when mobile, coil 41 is maintained at the not height of butt between conduit assembly bench S1 and warm table S2, and Here it is recesses the position.On the other hand, down position is an operating position, and coil 41 is around valve sleeve 10, and by flowing through high frequency electric, this valve sleeve 10 is by indirect.
Next, illustrate in valve sleeve 10 connecting duct 11 is installed, by the fixed method of soldering.At this,, use ring-type scolder 17 shown in Figure 3 for carrying out soldering.Therefore the internal diameter of scolder 17 is slightly larger than the external diameter of connecting duct 11, at the valve sleeve 10 (Group み Write む that packs into) before the connecting duct 11, insert scarfweld material 17 at connecting duct 11 in advance.
At first, at conduit assembly bench S1 configuration operation post 23, and carry out mounting as follows: the opening that is about to valve sleeve 10 is provided with towards the below, and it is positioned by the align member 24 that is located at this operation post 23.Then, in being arranged at the through hole 13a～13d that has step of valve sleeve 10, insert connecting duct 11a～11d successively.At this, the large-diameter portion 14 that has a through hole 13a～13d of step becomes the aperture greater than the external diameter of connecting duct 11a～11d, and because of chimeric length short, so only can not keep connection status to insert connecting duct 11.
Therefore,, the other end of connecting duct 11 is engaged with bar 28 with the center adjustment, make the center adjustment integrated with bar 28 and connecting duct 11 whenever when through hole 13 inserts 1 connecting duct 11.Insert the adjustment of logical center with bars 28 at inserting hole 27, and tilt, make below its holding section with connecting duct 11 becomes.For this reason, with the weight of bar 28, push the direction of step surface 16 of through hole 13 along connecting duct 11 and active force by the center adjustment.Its result surely not came off from through hole 13 with the connecting duct 11 that bar 28 is connected with slotting leading in the adjustment of the center of inserting hole 27, and its position and direction are fixed.Therefore, connecting duct 11 is carried out the center adjustment with respect to the through hole 13 that has step, with chimeric across the state that forms impartial slit G all around.
