As shown in figure 3, the exhaust gas valve 1 includes the spool 12 and valve seat 11 of coaxial arrangement, and in the spool 12 and valve seat 11,
It is provided with protrusion at the axle center of one, the matching hole with protrusion cooperation, and protrusion and cooperation are provided at the axle center of another one
When hole cooperates, the two remains face contact.
In the present embodiment, mutually matched protrusion and matching hole are set in valve seat 11 and spool 12, the two remains face
Contact, and the cooperation of the two is located inside valve seat 11 or spool 12, so that spool 11 and valve seat 12 face contact always.Together
When, due to protrusion and matching hole with valve seat 11 and spool 12 it is coaxial, spool 12 is transferred to the active force of valve seat 11 along the beginning
Eventually along the axis direction of valve seat 11.Compared with the prior art shown in FIG. 1, even if there are part size scattered errors for each component, still
It can guarantee the pass valve power stepless action from rocker arm assembly 3 in waste gate, so that when exhaust gas valve 1 is closed, valve seat disk
114 can with when the complete gluing, sealing of turbine box 2, i.e. 1 closed state of exhaust gas valve will not gas leakage so that 1 energy of exhaust gas valve
Enough play the role of improving low engine speed performance.
Specifically, as shown in figure 4, the upper surface of valve seat disk 114 is provided with coaxial first boss 111, this first
Boss 111 is part sphere shape, and for less than hemispheroidal part.Meanwhile as shown in figure 5, the spool disk 125 of spool 12 has
There is coaxial spool bore, and the first segment 121 of the spool bore is the conical structure cooperated with first boss 111, and should
The spherical surface of first boss 111 is bonded always with the circular conical surface of first segment 121, i.e., first boss 111 is remained with first segment 121
Conical surface contact, therefore, the Part-spherical first boss 111 are raised part, which is above-mentioned cooperation
Hole.Meanwhile the second segment of the spool bore is connecting hole, for the connection between spool 12 and valve seat 11, and as shown in figure 5, should
In spool bore, first segment 121 is located at the lower section of second segment.
On this basis, there is predetermined gap, i.e. the two does not connect directly between 12 lower surface of 11 upper surface of valve seat and spool
Touching, on the one hand, be capable of providing the space being axially moved between each component when closing valve, on the other hand, additionally it is possible to reduce valve seat 11 with
Dimension precision requirement when spool 12 is processed, it is often more important that, when 11 upper surface of valve seat and 12 lower surface of spool do not contact, so that
Valve seat 11 is only contacted by boss with matching hole with spool 12, to guarantee the two face contact always.
It is appreciated that raised part and matching hole are it is not necessary to pass through spherical first boss 111 and conical first segment
121 realize, can also be other shapes commonly used in the art, still, the spherical first boss 111 and cone first of coaxial arrangement
After section 121 cooperates, the axis of the two is overlapped, and can be guaranteed that the active force transmitted therebetween acts on the axis, that is, be made
For the axis of spool 12 and valve seat 11, and in the two engagement process, conical first segment 121 can be oriented to first boss 111
It into the first segment 121, and is coated in the first segment 121, to improve the precision and reliability of the two cooperation.
Further, as shown in figure 4, the valve seat 11 is additionally provided with coaxial cylindrical pin shaft 112, and the pin shaft
112 are located at 111 top of first boss, and cooperate with the second segment of above-mentioned spool bore.The pin shaft 112 is for connecting spool 12 and valve
Seat 11, as shown in figure 3, valve seat 11 and spool 12 are riveted by being located at the washer 13 of 125 top of spool disk, meanwhile, after riveting, pad
The lower surface of circle 13 and the upper surface of spool 12 have predetermined gap, so as to further to close valve when the axial of each component transport
It is dynamic that space is provided.
It should be noted that as shown in figure 3, the pin shaft 112 and second segment cooperate, and after cooperation, first boss 111 is located at
In first segment 121, and guarantee the spherical surface and circular conical surface tangent fitting always of the two.
In conclusion spool is being realized in the variable cross-section hole of upper end cylinder as shown in figure 5, spool bore is lower end cone
12 with valve seat 11 while connect, the leakproofness both improved.
In another embodiment, 114 upper surface of valve seat disk is provided with coaxial cylindrical boss, and boss is matched with through-hole
It closes, and is bonded always.
It is appreciated that mutually matched cylindrical boss and cylindrical hole are also able to maintain face contact in the present embodiment,
Meanwhile it is also possible that the active force between spool 12 and valve seat 11 acts on the axis of valve seat 11, to prevent exhaust gas valve 1 from leaking
Gas.But the centring property after spherical first boss 111 and conical first segment 121 cooperate in embodiment shown in Fig. 3-5 is aobvious
So more preferable, i.e., the first boss 111 of the structure and 121 concentricity of first segment are more preferable, therefore, anti-using the exhaust gas valve 1 of the structure
The effect of leak-stopping gas is more preferable, and therefore, present invention preferably employs the set-up modes in Fig. 3-5.
In addition, valve and valve rod pass through rivet interlacement, and at valve bottom in existing exhaust-driven turbo-charger exhaust-gas turbo charger exhaust gas valve
Portion welds or rivets.But under the action of air-flow, after welding or riveting, valve and rivet can rotate in valve rod hole, make
It obtains and generates abrasion between valve rod and valve due to relative rotation.When the exhaust gas valve when used for a long time, valve rod hole inner wall and rivet
Axis outer wall is worn due to relative rotation, and gap between the two increases, gas leakage when so as to cause exhaust gas valve in off position, shadow
Ring the low-speed performance of engine.When serious, rivet, which rubs, leads to exhaust gas defective valve, and engine can not work.
Based on this, as in Figure 3-5, exhaust gas valve 1 provided by the invention is additionally provided with limiting component, for limiting spool 12
With the relative rotation of valve seat 11, so that pin shaft 112 is reduced and second segment generates the risk of abrasion due to relative motion, so that two
Gap between person is smaller, and when exhaust gas valve 1 is in close state, closing valve external force can be correctly and efficiently transmitted in waste gate
The heart, so as to improve the low-speed performance of engine.
Specifically, as shown in figure 4, the edge of valve seat disk 114 has second boss 113, as shown in figure 5, spool disk 125
Edge has limiting slot 122, and when spool 2 and the cooperation of valve seat 1, which is connected in limiting slot 122, limiting slot
The circumferential movement of 122 both ends of the surface limitation second boss 113 circumferentially, and then limit the relative rotation of spool 2 and valve seat 1.Cause
This, mutually matched second boss 113 is above-mentioned limiting component with limiting slot 122.
Certainly, it can also be used it is not necessary to by second boss 113 and the realization of limiting slot 122 in above-mentioned limiting component
Its structure, for example, several baffles interfered can be arranged in spool disk 125 and valve seat disk 114, to prevent the circumferential phase of the two
To rotation.
Meanwhile the end face of limiting slot 122 radially forms intilted inclined-plane or cambered surface, when in air-flow and gravity etc.
Under the action of external force, there are when the trend of relative motion, opposite circumferentially rotate of the two is limited slot 122 for valve seat 11 and spool 12
It is limited with second boss 113, at this point, the inclined-plane of 122 end face of limiting slot or cambered surface can prevent its edge from axially trapping second boss
113, when closing valve, the space of spool 12 Yu 11 axial relative movement of valve seat is provided, simultaneously, additionally it is possible to reduce second boss 113
With shock loading when 122 axial relative movement of limiting slot, play the role of protecting limiting component, and guarantees valve seat 11 and spool
12 will not axial clamping stagnation at limiting slot 122.
Further, as shown in figure 5,125 periphery of spool disk of spool 12 links into an integrated entity with shaft 124, such as Fig. 2 institute
Show, 124 outer end of shaft is fixed with rocker arm assembly 3, which is controlled by the control device of engine, can when rotating
It drives the exhaust gas valve 1 to act relative to the waste gate of exhaust-driven turbo-charger exhaust-gas turbo charger, to realize opening or closing for exhaust path, and changes
Become its aperture.Spool disk 125 and 124 junction of shaft are provided with several reinforcing ribs 123.
The torque of engine control system output passes through itself and shaft 124 in the rocker arm assembly 3, the rocker arm assembly 3
Being fixedly connected between spool disk 125 transmits this torque to exhaust gas valve 1, to control the movement of exhaust gas valve 1, i.e. spool disk 125
The torque is transmitted with 124 junction of shaft, therefore, which, which is arranged several reinforcing ribs 123, can be improved the strong of the exhaust gas valve 1
Degree, and improve the accuracy of torque transmitting.
On the other hand, as shown in Figures 2 and 3, when the assembly of exhaust gas valve 1 is completed, valve seat disk 114 directly increases with exhaust gas turbine
The waste gate of depressor directly contacts.Therefore, valve seat disk 114 can be circular configuration, and have a diameter larger than engine exhaust turbine increasing
Therefore the diameter of depressor waste gate when exhaust gas valve 1 acts under the driving of control device, is always positioned at the top of waste gate, and
It will not fall into waste gate.Alternatively, the outer profile of valve seat disk 114 can have a straightway 1141, and 1 action process of exhaust gas valve
In, which is always positioned at the top of waste gate, so that exhaust gas valve 1 be avoided to fall into waste gate and prevent it from normal
