Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 3 is a pilot valve structural representation of the present utility model, and Fig. 4 (a), Fig. 4 (b) are respectively first kind of embodiment's the plan view and the left view of the link press span of pilot valve of the present utility model.
Specifically, as shown in Figure 3, pilot valve 11 has valve body 1, places the valve member 3 in the described valve body 1 to be connected with valve body 1 by welding manner with link press span 2. link press spans 2.The concrete structure of link press span 2 is shown in Fig. 4 (a), Fig. 4 (b).As can be seen, link press span 2 has sticking part 21 that fits with valve body 1 and first joint 31 that is oppositely arranged and second joint 32 that lays respectively at sticking part 21 both sides from Fig. 3, Fig. 4 (a), Fig. 4 (b).Wherein, sticking part 21 and valve body 1 link together by welding manner.In addition, has first bending part 33 between first joint 31 and the sticking part 21.By on link press span 2, processing this first bending part 33, thereby the area of contact between sticking part 21 and the valve body 1 is reduced.Because between valve body 1 and the link press span 2 is to be connected by welding manner, present embodiment is by taking to be connected with the mode of first bending part 33 between the sticking part 21 and first joint 31, the sticking part 21 of link press span 2 and the area of contact between the valve body 1 have been reduced, also just reduced demand, thereby also reduced cost of production scolder.
Certainly, according to demand of practical production, in the present embodiment, shown in Fig. 4 (a), first bending part 33 of link press span 2 has 2 bending sections.It can certainly be the bending section more than 3.Simultaneously, the bending part of first bending part 33 is provided with flange further guarantees link press span 2 as reinforcing part 35 intensity by punching press.
In addition, as shown in Figure 3, the surface of contact of sticking part 21 and valve body 1 along the length L 1 of valve body 1 axial direction less than between first joint 31 and second joint 32 along the minimum range L2 of valve body 1 axial direction.(should be noted that, because the needs of producing can non-parallelly be provided with between first joint 31 of the link press span 2 of pilot valve 11 of the present utility model and second joint 32, so L2 should get the minimum range between first joint 31 and second joint 32.) owing to need pilot valve to be fixed on the main valve,, and under the prerequisite that guarantees weld strength, reduce the length that the L1 size has just reduced the face that is welded to connect so often the size of L2 cannot change by support and link press span, saved scolder.
Shown in Fig. 5 (a), Fig. 5 (b), be respectively second kind of embodiment's the plan view and the left view of the link press span 2 of the utility model pilot valve 11.As shown in the figure, what present embodiment was different with first embodiment is that first bending part 33 of link press span 2 has a bending section, and this bending section is a plane shape.Simultaneously, the bending part of first bending part 33 is provided with flange further guarantees link press span 2 as reinforcing part 35 intensity by punching press.
Shown in Fig. 6 (a), Fig. 6 (b), be the third embodiment's of the link press span 2 of the utility model pilot valve 11 plan view and left view.As shown in the figure, first bending part 33 of link press span 2 has two bending sections, and different with first kind of embodiment of the link press span 2 of pilot valve 11 is to be connected with second bending part 34 between second joint 32 and the sticking part 21.Second bending part 34 has a bending section, and this bending section is a plane.Certainly, first bending part 33 of present embodiment also may have the bending section more than or three, and in like manner, second bending part 34 also can have plural bending section.There is the area of contact that can further reduce valve body 1 and sticking part 21 in the time of first bending part 33 and second bending part 34, thereby reduces demand, further reduce cost scolder.Simultaneously, the bending part of first bending part 33 is provided with flange further guarantees link press span 2 as reinforcing part 35 intensity by punching press in the present embodiment.
Shown in Fig. 7 (a), Fig. 7 (b), be respectively the plan view and the left view of the utility model selector valve structure.In the present embodiment, this selector valve is specially four-way change-over valve.Four-way change-over valve shown in Fig. 7 (a), Fig. 7 (b) comprises main valve 14, support 13, pilot valve 11 and electromagnetic coil 12, is welded with link press span 2 on the pilot valve 11, and in the present embodiment, the link press span 2 of pilot valve 11 is the link press span shown in Fig. 4 (a), Fig. 4 (b).During assembling, pilot valve 11 is fixed on the main valve 14 by support 13 and link press span 2.During assembling, at first support 13 is welded on the main valve 14, afterwards, the main valve 14 that is welded with support 13 is fixed together at first joint 31 and second joint, 32 places of link press span 2 by the link press span 2 of support 13 with pilot valve 11, then be fastenedly connected, refill distribution magnetic coil 12 at last by screw 15.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
