Description
Technical field:
The utility model belongs to automobile engine accessory technical field, and in particular to the included installation Anti-error structure valve block of one kind
Throttle valve body.
Background technique:
Air throttle is the device for adjusting engine air input, and air throttle is mounted on the air inlet of engine suction manifold
On, the opening angle of air throttle middle valve plate is adjusted by external force, can effectively adjust the air-flow size that outside air enters engine,
And then adjusting power of engine.And the valve block in air throttle is to fit into shaft hole, is rotated after fixed with shaft, when assembly, is wanted
Pay special attention to directionality, if assembly it is reversed will lead to it is stuck when valve block is closed, can not adjusting engine air input, cause to send out
Motivation catastrophe failure.
Utility model content:
The utility model is to overcome drawbacks described above, provides a kind of throttle valve body of included installation Anti-error structure valve block,
The valve block of included installation Anti-error structure is installed on the throttle valve body, can avoid causing in assembling process because reversely installing therefore
The generation of barrier can effectively reduce engine failure incidence, improve product service life.
The technical solution adopted in the utility model is: a kind of throttle valve body of included installation Anti-error structure valve block, packet
Include: throttle valve body and valve block are equipped with inlet channel in the throttler valve body, are equipped with shaft in the intake channel, and described turn
The axis of axis and the axis perpendicular of throttle valve body, offer shaft hole in shaft；The valve block is flake, in valve block
Center line on be equipped at intervals with two screw holes, be equipped with salient point, and the stretching height of salient point in the side of two screw hole lines
Greater than the thickness of valve block, the vertical range of center line is greater than the radius of shaft where salient point and screw hole, and valve block is far from salient point
After shaft hole is inserted into one end, the edge of valve block and the inner wall close fit of inlet channel.
Preferably, the stretching height of the salient point is 1.5 times of throttle slice thickness.
Preferably, the draw direction of the salient point is to stretch to above or below horizontal positioned valve block.
Preferably, the salient point is spaced two, and the draw direction of two salient points is identical, and two salient points are located at
Screw hole it is ipsilateral, and cross two salient point centers of circle line and screw hole where centerline parallel.
The beneficial effects of the utility model are:
1, by the way that salient point is arranged on valve block, valve block is made not generate the generation of loading error phenomenon in assembly；
2, the design feature that height is greater than throttle slice thickness is stretched using salient point, cannot achieve assembly in setup error, saved
The time of worker's assembly is saved, work task efficiency is improved.
3, it after throttle valve body is by installation Anti-error structure valve block, can avoid leading to throttle valve body because of the installation mistake of valve block
Assembly is done over again or even is scrapped, and process of producing product quality level can be effectively improved.

Specific embodiment:
As depicted in figs. 1 and 2, the utility model devises a kind of throttle valve body of included installation Anti-error structure valve block,
Include: throttle valve body 4 and valve block 1, be equipped with inlet channel in the throttle valve body 4, be equipped with shaft 5 in the intake channel,
The axis of the shaft 5 and the axis perpendicular of throttle valve body 4, as shown in fig. 6, offering shaft hole 51 in shaft 5.Such as
Shown in Fig. 3 to Fig. 5, the valve block 1 be flake, the longitudinal section parallelogram of valve block 1, on the center line of valve block 1 with
The center of circle of valve block 1 is that midpoint is symmetrically arranged with two screw holes 2, is equipped with salient point 3, and salient point 3 in the side of two 2 lines of screw hole
Positioned at the side of the angle of upper surface and bevel edge in obtuse angle.It is convex in order to make the position of salient point 3 not influence the correct installation of valve block 1
Point 3 is greater than the radius of shaft 5 with the vertical range of 2 place center line of screw hole.In order to enable salient point 3 to play in loading error
The effect of prompt, the stretching height of salient point 3 is 1.5 times of 1 thickness of valve block, in loading error, resistance of the valve block 1 due to salient point 3
Gear can not be installed in place in shaft hole 51.The draw direction of the salient point 3 can be along the stretching of the top of horizontal positioned valve block 1
Or stretched along to the lower section of horizontal positioned valve block 1, the quantity of the salient point 3 can be one, be also possible to two, if convex
Putting 3 is two, and the draw direction of two salient points 3 is identical, and two salient points 3 are arranged at intervals on the ipsilateral of screw hole 2, and two excessively convex
The line and 2 place centerline parallel of screw hole in 3 centers of circle of point.
Since initial position of the valve block 1 in throttle valve body 4 is to close inlet channel, when throttle valve body 4 works, turn
The band moving valve plate 1 under the driving of external force of axis 5 rotates, and opens inlet channel, so valve block 1 is inserted into shaft far from one end of salient point 3
Behind hole 51, the edge of valve block 1 and the inner wall close fit of inlet channel, the cooperation by shaft 5 with moving valve plate 1 Yu inlet channel
That realizes throttle valve body 4 opens or closes state.
Assembling process:
When valve block 1 and throttle valve body 4 are assembled, rotating shaft 5 first keeps shaft hole 51 horizontal, assembly is correct
When, as depicted in figs. 1 and 2, operator holds valve block 1, and salient point 3 is located at the top of valve block 1, first by valve block 1 without convex
Point 3 side first is passed through out of shaft hole 51, then hold up valve block 1 by the direction E rotating shaft 5, by bolt by valve block 1 with
Shaft 5 is fixed by screw hole 2, last shaft 5 with moving valve plate 1 be restored to shaft 5 it is static when original state, valve block 1
After return, throttle valve body 4 is in close state, and the edge of valve block 1 is formed by wedge angle and contacts with the inner wall of inlet channel, is risen
To sealing function；When loading error, as shown in fig. 7, if the side for having salient point 3 on valve block 1 is first extend into shaft hole 51
Interior, since the stretching height of salient point 3 on valve block 1 is greater than the internal diameter height of shaft hole 51, valve block 1 can not assemble in place with shaft 5,
Bolt in shaft 5 can not be installed, assembly failure.
The preferable specific embodiment of the above, only the utility model, these specific embodiments are all based on this
Different implementations under utility model general idea, and the protection scope of the utility model is not limited thereto, it is any ripe
Know those skilled in the art within the technical scope disclosed by the utility model, any changes or substitutions that can be easily thought of, all
It should cover and be within the protection scope of the utility model.Therefore, the protection scope of the utility model should be with claims
Subject to protection scope.
