Described impact resistance eccentric reducer, including radial section all in circular body, body points to along an end
Another end direction, its internal diameter is become larger by little, and external diameter is also become larger by little accordingly, the end that pipe diameter is less
Stretching out the little head end of formation along its axis, the bigger end of pipe diameter stretches out formation stub end along its axis, along little
Head end or stub end axis direction, body outer circular section projection is tangential on a bit, and in body, circular section projection is also tangential on one
Point, on body a certain radial section annulus, the center of circle with two points corresponding to these two points of tangency with this radial section annulus is total to
Line, described stub end coupling has spoiler disposed within, described spoiler offers the main through hole of through round shape, main through hole
Internal diameter is not more than little head end internal diameter；
When spoiler within stub end is positioned at a certain orientation, main through-bore axis can overlap with little head end axis.
Further, stub end inwall offers locating slot along axis, spoiler is correspondingly provided with locating piece；
Locating piece matches with locating slot, when spoiler being placed in stub end, and main through-bore axis and little head end axis phase
Overlap mutually.
Further, locating slot is opened on stub end inwall the point corresponding with circular section projection points of tangency in body
At link position.
Further, described spoiler is further opened with some through auxiliary through holes.
Further, described auxiliary through hole has some row, every string auxiliary through hole center of circle to divide equally accordingly to cut with spoiler in one section
On the circular arc that face circle is concentric.
Further, described auxiliary through-bore axis is obliquely installed, auxiliary through-bore axis all with little head end axes intersect in same point,
This joining is positioned at tubular body.
This impact resistance eccentric reducer is applicable to manage interior medium and is flowed to the concrete application scenario of little head end by stub end, its
Stub end is provided with spoiler, makes the main through-bore axis on spoiler coincide with little head end axis during use, and medium is by major part
When end flows to little head end, due to the choked flow effect of spoiler, flow through little head end vertically by the medium of the main through hole of spoiler, fly
The medium spattering to caliber the tube wall part gradually changed is little, and its impact energy also will not be very big, thus play effectively protection should
The effect of section tubular wall safety, has reached to improve this impact resistance eccentric reducer the most accordingly and has used safety, extended this impact resistance
The purpose in eccentric reducer service life.

Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Impact resistance eccentric reducer described in the utility model, as it can be seen, include that radial section is all in circular body
3, body 3 points to another end direction along an end, and its internal diameter is become larger by little, and external diameter is also gradually become by little accordingly
Greatly, the end that body 3 diameter is less stretches out along its axis and forms little head end 1, and the end that body 3 is relatively large in diameter is along its axis
Stretch out formation stub end 2, and along little head end 1 or stub end 2 axis direction, the projection of body 3 outer circular section is tangential on a bit,
In body 3, circular section projection is also tangential on a bit, with two corresponding to these two points of tangency on body 3 a certain radial section annulus
Individual point and the center of circle conllinear of this radial section annulus, described stub end 2 coupling has spoiler 4 disposed within, described spoiler 4
On offer the main through hole of through round shape 5, main through hole 5 internal diameter is not more than little head end 1 internal diameter；
When spoiler 4 within stub end 2 is positioned at a certain orientation, main through hole 5 axis and little head end 1 axis energy phase mutual respect
Close.
This impact resistance eccentric reducer is applicable to manage interior medium and is flowed to the concrete application scenario of little head end by stub end, its
Stub end is provided with spoiler 4, makes main through hole 5 axis on spoiler 4 coincide with little head end 1 axis during use, medium by
When stub end flows to little head end, due to the choked flow effect of spoiler 4, flow through little vertically by the medium of the main through hole of spoiler 45
Head end 1, the medium splashing to the tube wall part that caliber gradually changes is little, and its impact energy also will not be very big, thus has played
The effect of this section tubular wall safety of effect protection, has reached to improve this impact resistance eccentric reducer the most accordingly and has used safety, extended
The purpose in this impact resistance eccentric reducer service life.
In this impact resistance eccentric reducer, stub end 2 inwall offers locating slot 7 along axis, spoiler 4 sets accordingly
It is equipped with locating piece 8；
Locating piece 8 matches with locating slot 7, when spoiler 4 being placed in stub end 2, and main through hole 5 axis and little head end 1
Axis overlaps.
Further, locating slot 7 is opened on stub end 2 inwall corresponding with circular section projection points of tangency in body 3
At the link position of point.
In this impact resistance eccentric reducer, described spoiler 4 is further opened with some through auxiliary through holes 6, auxiliary through hole 6 energy
Enough play raising spoiler 4 unit interval effect by flow.
Specifically, described auxiliary through hole 6 has some row, every string auxiliary through hole 6 center of circle to divide equally accordingly in one section and spoiler 4
On the circular arc that cross section circle is concentric.
Preferably, described auxiliary through hole 6 axis is obliquely installed, auxiliary through hole 6 axis all with little head end 1 axes intersect in same
Point, it is internal that this joining is positioned at body 3, and this kind of structure of auxiliary through hole 6 can make to be pointed to by the medium flow path direction of auxiliary through hole 6 to lead to
Cross the medium stream of main through hole 5, without pointing to the tube wall part that caliber gradually changes, pass through improving spoiler 4 unit interval
Also above-mentioned tube wall part will not be caused too much impact while flow.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
