With reference to Fig. 1～Fig. 5, a mode of execution the when control valve unit that will the present invention relates to is used as electric control valve is explained.
As shown in Figure 1, electric control valve has clack box 11.Clack box 11 is the fabricated metalss that formed by stainless steel, Cuprum alloy etc., and is formed with valve chamber 12, valve port 13, stem guiding hole 14, transverse joint attachment hole 15, following square joint attachment hole 16.
At the top part of clack box 11, be formed with the lower cover mosaic process 23 concentric highlightedly with stem guiding hole 14.In lower cover mosaic process 23, the chimeric center hole 33 that the central part of the bottom surface sections 32 that breakthrough form is formed in cup-shaped lower cover member 31 is arranged.Lower cover member 31 is by the ca(u)lk portion 28 and the soldering portion 29 of temporary fixed usefulness, and is fixedly installed in clack box 11.For the soldering of the lower cover member 31 relative clack boxes 11 by soldering portion 29, after overall structure explanation, further describe the electric control valve of present embodiment.
The open lower side edge portion 58 of rotor case 52 of the jar shape of stepper motor 51 is butt-welded in the upside peristome portion 34 of lower cover member 31 airtight shape.In addition, lower cover member 31, rotor case 52 are made of stainless steel etc.
On the peripheral part of rotor case 52, be installed with the stator coil parts 57 of stepper motor 51.Flow through impulsive current by coil portion, and rotor 55 is rotated with the angle of rotation corresponding with its umber of pulse stator coil parts 57.
Outside thread formation portion 25 cylindraceous and stem guiding hole 14 are outstanding with one heart to be formed in the lower cover mosaic process 23 of clack box 11.Outside thread formation portion 25 is in the rotor chamber 54, and outside thread 26 is formed at the outer circumferential surface section of outside thread formation portion 25.Rotor 55 is formed with internal thread 58 at central part.Internal thread 58 screws togather with outside thread 26.
The upper end part 27 of needle-valve body 21 is by assembling set 59, collar cartridge unit 60, compression helical spring 61 etc., and quilt can be connected on the rotor 55 with the relative rotation.
The rotation of rotor 55 screws togather by internal thread 58 and outside thread 26, move and be transformed to axial direction, thereby the axial direction of rotor 55 moves and is delivered to needle-valve body 21.Thus, the axial direction position of decision needle-valve body 21, thus control flows is through the fluid flow of valve port 13 quantitatively.
In addition, on rotor case 52 and rotor 55, be assembled with the maximum rotational position of the valve opening position that is used to set rotor 55 and close the arrestment mechanism 62 of the maximum rotational position of valve direction.
With reference to Fig. 2～Fig. 5, to doing to describe in detail by the situation of soldering portion 29 relative clack box 11 welding lower cover member 31.
As shown in Figure 2, lower cover mosaic process 23 has the outer peripheral surface 24 concentric with stem guiding hole 14.Lower cover member 31 is concentric chimeric with the outer peripheral surface 24 of lower cover mosaic process 23 with the inner peripheral surface of center hole 33.
As Fig. 3～shown in Figure 4, on lower cover planar surface portion 36, by plastic deformations such as mold pressing processing processing, the outstanding projection 38 that is formed with.Projection 38 is semicircle, and is formed at three places at interval with 120 degree around center hole 33.As shown in Figure 2, because projection 38, and forming joint clearance of brazing Ta on lower cover planar surface portion 36 and the clack box 11 between the planar surface portion 37.The size of joint clearance of brazing Ta is set at appropriate value by the height of control projection 38.
Because joint clearance of brazing Ta is covered by the scolder of soldering portion 29, so become the mating face of scolder with the roughly whole face of last planar surface portion 37 opposed parts in roughly whole of the last planar surface portion 37 of clack box 11 and the lower cover planar surface portion 36, thereby can stably guarantee bigger bonding area.Thus, clack box 11 with lower cover member 31 with required soldering strength by soldering.
As Fig. 3～shown in Figure 4, radial direction along center hole 33 is observed, on the position identical with the position that is formed with projection 38, by with the processing simultaneously of the piercing of center hole 33, and the partial cut that is formed with the inner peripheral surface part of center hole 33 is the grooving portion 39 of concavity.Be formed with grooving portion 39 by each projection 38, as shown in Figure 3, be set with the chimeric gap Tb of being wider than other parts (not being provided with between the outer peripheral surface 24 of the inner peripheral surface of center hole 33 of part of grooving portion 39 and lower cover mosaic process 23) between the outer peripheral surface 24 of itself and lower cover mosaic process 23.
As shown in Figure 5, grooving portion 39 is set, thereby its yielding shape portion as the distortion of the internal diameter shape that is used to absorb the center hole 33 that is caused by the plastic deformation processing of projection 38 is played a role according to each projection 38.
Gap between the outer peripheral surface 24 of the inner peripheral surface of the center hole 33 of the part that grooving portion 39 is not set and lower cover mosaic process 23 is: for keep lower cover member 31 with the coaxality of clack box 11 the high-precision significant dimensions of needs position.Relatively therewith, the yielding shape portion of the distortion of the internal diameter shape of the center hole 33 that grooving portion 39 causes as the plastic deformation processing that is used to absorb by projection 38 and playing a role, thus can avoid plastic deformation to process the inner peripheral surface of the center hole 33 that caused influence relates to the part that is not provided with grooving portion 39.
Thus, the circularity of center hole 33 that is not provided with the part of grooving portion 39 is kept, the high-precision significant dimensions of the needs position for the coaxality that keeps lower cover member 31 and clack box 11, even if the chimeric gap that promptly is not provided with between the outer peripheral surface 24 of the inner peripheral surface of center hole 33 of part of grooving portion 39 and lower cover mosaic process 23 is established lessly, can not take place as lower cover member 31 being fitted to the unfavorable condition of the lower cover mosaic process 23 of clack box 11 yet, by establishing chimeric gap minimum, can keep the concentric installation precision of lower cover member 31 relative clack boxes 11 accurately.
And, the effect of the exhaust passageway when the chimeric gap Tb that is caused by grooving portion 39 plays the relative soldering of scolder portion 29 just joint clearance of brazing Ta enters.Thus, when the relative joint clearance of brazing Ta of scolder soaks into, can avoid this part generation air accumulation, avoid causing reduction in strength by brazing defect.
And, also enter into grooving portion 39 by scolder, improve soldering strength.
In addition, the shape of projection 38 is not limited to the such semicircle shape of grooving portion 39, can be as shown in Figure 6, is formed at the circular projection 40 away from the position of grooving portion 39, also can be tetragonal projection 41 as shown in Figure 7.And the number of these projections is not limited to three, can be as shown in Figure 7 four, also can be that they are above a plurality of.
And, be used for the projection of joint clearance of brazing, can be as Fig. 8, shown in Figure 9, on position, roughly form identical circular-arc projection 42,43 on the whole circumference at center hole 33 away from the outside of the circumference of center hole 33.Under this occasion, can be on the position that is not provided with projection 42,43, as making a concession the hole 44 that shape portion forms grooving portion 39 or connects the bottom 32 of lower cover member 31.
In this embodiment, even if after having processed projection 42,43, can therefore can there be the hole processing of the circle of distortion against mould around center hole hole 33 yet yet.
And the scolder as the each several part of soldering portion 17,19,29 as shown in figure 10, can adopt welding ring 45,46,47.
At this moment, welding ring 45 is arranged at the opening end of the outer circumferential face of transverse joint attachment hole 15 relative clack boxes 11, but because this part is circumferential surface and injustice, so if flat general welding ring 45, then welding ring 45 only contacts with the periphery millet cake of clack box 11 in the top and the bottom of transverse joint attachment hole 15, and its two side portions still is in the state away from the outer circumferential face of clack box 11.
When carrying out furnace brazing, following tendency is arranged: the less connected element (transverse connecting pipe 18) of thermal capacity heats up prior to clack box 11 because of atmosphere temperature, when reaching the melt temperature of scolder, with on clack box 11 position contacting by the wicking scolder to clack box 11 side shiftings, but away from the position on, because the temperature of clack box 11 is lower,, and remain in original position so scolder is mobile.
When scolder is detained, not only cause problem of appearance, and owing to scolder fully can't be supplied to the anastomosis part, so soldering strength deficiency, or the scolder of fusion is stranded in same position, thereby might corrode the material that is welded, and may cause substrate intensity to reduce and even destroy.
Relatively therewith, as Figure 10, shown in Figure 11, opening end at the outer circumferential face of transverse joint attachment hole (cross-drilled hole) the 15 relative clack boxes 11 of the clack box 11 that inserts transverse connecting pipe 18, the chamfer shape portion 48 that setting forms by chamfer machining, thus, in supply during part, the part increase that contacts between welding ring 45 and the clack box 11, as shown in figure 12, welding ring 45 and clack box 11 do not have chamfer shape portion 48 apart from the d ratio time more approaching.
By chamfer shape portion 48, the part that welding ring 45 is contacted with clack box 11 increases, thus, when melt solder, increase by the amount of movement of wicking to clack box 11 sides, and clack box 11 is approaching with the distance of welding ring 45, and thus, the scolder of fusion diffusion arrives clack box 11, and same with contacting part, soak into from here in the gap between clack box 11 and the transverse connecting pipe 18.
The chamfering of the opening end of the outer circumferential face of transverse joint attachment hole 18 relative clack boxes 11, be the conical processing that carry out columnar relatively side, so can't process the whole circumference scope of transverse joint attachment hole 15 equably, as shown in figure 11, darker chamfer machining is carried out in top and the bottom at transverse joint attachment hole 15, but also can increase the part that welding ring 45 contacts with clack box 11 by this chamfering, what can obtain welding ring 45 and clack box 11 compares more approaching effect apart from d with the occasion that does not have chamfer shape portion 48.
And, as shown in figure 13, can the spot-facing shape portion 49 that be formed by spot-facing be set at the opening end of the outer circumferential face of transverse joint attachment hole (cross-drilled hole) 15 relative clack boxes 11.For to becoming columnar side to process, make this spot-facing darker at the above-below direction of cross-drilled hole, and more shallow at left and right directions, thus, when the supply part, the whole periphery of welding ring 45 contacts with clack box 11, as shown in figure 14, can make the span between welding ring 45 and the clack box 11 is zero.
And, as shown in figure 15, be processed as R shape by external diameter corner part with spot-facing, further increase the contacting part between welding ring 45 and the clack box 11, thereby promote the fusion of the scolder that causes by transmission of heat.And the scolder that can reduce fusion is left in corner part and the situation of wasting.
