Description
Technical field
The utility model belongs to diesel engine technologies field, is related to a kind of diesel engine Venturi tube.
Background technology
The parts aggregate for air or gaseous mixture being imported cylinder calls engine aspirating system, and venturi
Pipe is one of which connection formed pipe, and engine aspirating system provides that an intake resistance is small, and charging efficiency is high for engine,
Combustion mixture is uniform, the big passage into engine cylinder-body of strength of vortex.
On the market such Venturi tube typically using gravity, low pressure, sand casting process, and these casting techniques have it is following
Defect：1st, the visual quality of casting is poor, and the error of blank dimension is big；2nd, during much time using, sealing effectiveness is undesirable,
Production capacity can not meet customer requirement, Seepage often occur in online installation and engineering use.
The content of the invention
For the utility model in view of the above-mentioned problems, providing a kind of diesel engine Venturi tube, the Venturi tube is monoblock type
Structure, good sealing effect.
According to the technical solution of the utility model：A kind of diesel engine Venturi tube, including tube body, the tube body
Interior side is arrival end, and it is the homogeneous circular hole of internal diameter on the outside of both ports of export, arrival end, the port of export that opposite side, which is, entrance
Hold the tapered shape in position that is connected with both port of export inner sides, it is characterised in that：Tube body surface is provided with nozzle of air supply structure, institute
State nozzle of air supply structure and be connected to both arrival end and the port of export connection, nozzle of air supply structure includes first jet, second
Nozzle, the 3rd nozzle, the 4th nozzle, after connection is converged in the first jet, second nozzle, the 3rd nozzle, the 4th nozzle bottom
With the intracavity inter-connection of tube body.
As further improvement of the utility model, the rectangular convex of nozzle of air supply structure, and nozzle of air supply knot
Structure is connected with tube body surface in arc transition.
As further improvement of the utility model, the outer end of the arrival end is flange face, and arrival end is provided with connection
Hole.
It is of the present utility model to have technical effect that：The utility model product structure advantages of simple, by using monoblock type knot
Structure causes the phenomenon that product will not leak, sealed reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.

As shown in figure 1, the utility model is a kind of diesel engine Venturi tube, including tube body 1, the tube body 1
Interior side is arrival end 2, and opposite side is the port of export 3, and both outsides of arrival end 2, the port of export 3 are the homogeneous circular hole of internal diameter,
Be connected the tapered shape in position on the inside of both arrival end 2 and the port of export 3, and the surface of tube body 1 is provided with nozzle of air supply structure 4, described
Nozzle of air supply structure 4 is connected to both connections of arrival end 2 and the port of export 3, nozzle of air supply structure 4 include first jet 4-1,
Second nozzle 4-2, the 3rd nozzle 4-3, the 4th nozzle 4-4, the first jet 4-1, second nozzle 4-2, the 3rd nozzle 4-3,
Converge intracavity inter-connection with tube body 1 after connection in 4th nozzle 4-4 bottoms.First jet 4-1 is main burner, second nozzle 4-
2nd, the 3rd nozzle 4-3, the internal diameter of the 4th tri- nozzles of nozzle 4-4 are in the same size.
4 rectangular convex of nozzle of air supply structure, rectangular preiection shape convenient card set position, when in use, will not occur to turn
It is dynamic, and nozzle of air supply structure 4 is connected with the surface of tube body 1 in arc transition.
The outer end of arrival end 2 is flange face, and arrival end 2 is provided with connecting hole.During concrete application, the port of export 3
Outer face is typically provided raised clamping structure.
The utility model product structure simple designs are skillfully constructed rationally, by using monolithic construction so that body is close
Envelope is reliable, the problem of will not leaking in use, and monolithic construction.
