Embodiment
Description to one or more preferred embodiments only is exemplary in essence below, and is intended to limit the present invention, its application or purposes absolutely not.
Fig. 1 to Fig. 3 illustrates a valving 10, and it comprises a single-piece flow control member 22 and has described in the assembly process of this valving 10 a kind of method with these flow control member 22 contrapositions.This valving 10 comprises a valve body 12, and this valve body has 14 and outlets 16 of an inlet.This valve body 12 is at this inlet 14 and should limit the path that fluid flows between the outlet 16.The fluid of this valve body 12 of flowing through can be the flowing medium of any kind, wherein can use a valve that comprises a fluid control member 22.This particular of the present invention has been described a valve body 12, it is the parts as an exhaust gas recirculatioon (EGR) valve member, and the flowing medium that flows through valve body 12 is from circulate the once more exhaust of return engine intake manifold of enmgine exhaust cup.Valve seat 18 with a hole 20 is included in this valve body 12 and at this inlet 14 and export in the fluid flow path between 16.This valve seat 18 can be pressurizedly to be installed to a separate part in this valve body 12 or it can be cast in or integral body is formed in this valve body 12.
This flow control member 22 is configured to optionally engage with this valve seat 18, so that seal this hole 20 and block this inlet 14 and the fluid of outlet between 16 flows.This flow control member 22 is integrally formed single piece components with a valve part 24, and it is configured to cooperate with this valve seat 18 and with a surface of its sealing.This flow control member 22 also has a valve extension 26, and this valve extension is extended and is defined as extending to more than of this flow control member 22 from valve part 24 and helps to open and close valve seat 18 necessary parts.
This valve extension 26 is illustrated as an annular wall around the part of a valve rod 30 in the drawings.Yet valve extension 26 is not to be a ring wall around the part of this valve rod 30; But can adopt various ways and needn't extend very long distance from this valve part 24.This valve extension 24 can provide many advantages, such as coking and/or deflect flow.In this embodiment of the present invention, the effect of this valve extension 26 is that the protection valve rod is avoided directly contacting with the flowing medium in the hole 20 of this valve seat 18 of flowing through from this inlet 14.By preventing that flowing medium from contacting with this valve rod 30, can significantly reduce the coke that on valve rod 30, takes place and form.
This flow control member 22 also has a handle 28 that centers on the longitudinal axis of this valve rod 30 on the whole and form.Fig. 1 extremely this handle 28 shown in Figure 2 has an opening end, and this handle 28 shown in Fig. 3 is slightly different, and it has a closed end 35 and forms a blind hole.This valve rod 30 has a movable terminal 32, and it is configured to slip among this handle 28.Radial groove 34 is formed on the surface of this valve rod 30 near these movable terminal 32 parts.This radial groove 34 also is configured to slide in this handle 28.This valve rod 30 is connected on this flow control member 22 by form a crooked edge 38 in this handle 28 afterwards, thereby handle 28 has this bending edge 38 that the position of the radial groove 34 on this valve rod 30 forms.In case having formed should bending edge 38, this flow control member 22 just will vertically move with the slip of this valve rod 30, with the hole 20 that opens and closes this valve seat 18.
Fig. 1 to Fig. 3 shows the process that is used at this valving 10 of assembling with a kind of method of these flow control member 22 contrapositions, and this valve part 24 will be established the locality and is sitting on this valve seat 18 to guarantee suitable valve operation like this.Fig. 1 shows this flow control member 22 is positioned over the locational first step that is sitting in this valve seat 18.Although Fig. 1 shows this flow control member 22 and is placed in and is sitting on this valve seat 18, for this flow control member 22 is placed on for any pre-position of this valve seat, it all within the scope of the present invention.This flow control member 22 is positioned as the hole 20 that makes this handle 28 extend through this valve seat 18.Thereby, the movable terminal 32 of this valve rod 30 make this movable terminal 32 enter this handle 28 so being slided to put in place.Fig. 2 shows this valve rod and is placed and puts in place.The contraposition of this valve rod 30 also is included in this valve body 12 sleeve pipe 40 is inserted into appropriate depth.The needs that use pad or other space compensation spare have been got rid of in the suitable contraposition that realizes this valve rod and this sleeve pipe 40.In case realized contraposition, this handle 28 is just by these bending edge 38 clampings, so that this flow control member 22 is connected to this valve rod 30.
Fig. 3 shows the tie point between this guard valve 22 and this valve rod 30.Shown in Figure 1 and Fig. 2 slightly difference are that this handle 28 has a closed ends or blind hole, and this valve rod 30 slips into wherein.This will guarantee not have by means of the leakage of the tie point between this handle 28 and this valve rod 30 by this valve seat 18.This bending edge 38 that this flow control member 22 is held on this valve rod 30 is formed on this radial groove 34 places.It also is within the scope of the present invention that utilization other devices except this bending edge 38 are fixed in this valve rod 30 with this flow control member 22.For example, can this valve rod 30 be connected on this flow control member 22 with tackiness agent, soldering or laser bonding.Fig. 3 shows the close-up illustration of this radial groove 34 of formation place of this bending edge 38.Knurled portion 36 on the movable terminal 32 of this valve rod 30 is placed in contiguous this radial groove 34.This knurled portions 36 works in this valve rod 30 slides into the step of handle 28 by unwanted move that prevents this valve rod 30 in assembly process.
Fig. 4 shows an alternate embodiment of a valving 100.This particular of the present invention has a flow control member 102, and it has improved slightly structure.This flow control member 102 has a handle 104 in the hole 20 that does not extend to this valve seat 18.This valve seat 18 is closed by a lip-deep annular shoulder 106 that is sitting in this valve seat 18.This handle 104 is used in the mode that is similar to the embodiment of the present invention described in Fig. 1 to Fig. 3 this flow control member 102 being connected with this valve rod 30.That is, the end of this valve rod 30 slides into this handle 104, and forms crooked edge 34 between this handle 104 and this valve rod 30.This bending edge 34 is connected this flow control member 102 with this valve rod 30, thereby in the operating process of this valving 100, this flow control member 102 is along with this valve rod moves.
Explanation of the present invention only is exemplary in itself, therefore, all should be in the scope of the present invention in the various variations that do not deviate from aim of the present invention.These change should not be considered to deviate from the spirit and scope of the present invention.
