Description
Technical field
The utility model belongs to technical field of engines, is related to a kind of diesel engine gaseous mixture connecting tube.
Background technology
The parts aggregate for air or gaseous mixture being imported cylinder calls engine aspirating system, and gaseous mixture
Connecting tube is one of which connection formed pipe, small, inflation effect that engine aspirating system for engine provides an intake resistance
Rate is high, and combustion mixture is uniform, the big passage into engine cylinder-body of strength of vortex.Existing gas connection pipe is generally interior
The homogeneous straight tube in footpath, it is unfavorable for gas in use and is sufficiently mixed.
The content of the invention
For the utility model in view of the above-mentioned problems, providing a kind of diesel engine gaseous mixture connecting tube, the connecting tube can be effective
So that gas is sufficiently mixed.
According to the technical solution of the utility model：A kind of diesel engine gaseous mixture connecting tube, it is characterised in that：Including method
Blue seat, integrally connected sectorial cavity on the flange seat, the sectorial cavity other end fix cone connection, the cone connection
Outer face is fixedly connected with straight tube, and straight tube outer face sets adpting flange；Pass through arc transition between the adpting flange and straight tube
Portion connects, the tube surfaces fixing support rack of the straight tube, and the both sides that straight tube is corresponded on support frame set a connection respectively
Post.
As further improvement of the utility model, the cone connection be connected with straight tube one end internal diameter be less than cone
Shape connecting portion is connected the internal diameter of one end with sectorial cavity.
As further improvement of the utility model, support frame as described above and the both ends of the surface of straight tube connection are arc mistake
Cross.
As further improvement of the utility model, connecting hole is opened up on the flange seat and adpting flange, and connect
Hole is counterbore.
It is of the present utility model to have technical effect that：The utility model product structure advantages of simple, by being set on body
One sectorial cavity, gas mixing effect can be effectively improved, gas is entered in sectorial cavity by cone connection, due to taper
The effect of connecting portion, gas has the effect of a diffusion when entering in sectorial cavity, while whirlpool is formed in sectorial cavity
Stream, realize the purpose of gas mixing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
In Fig. 1, including flange seat 1, sectorial cavity 2, cone connection 3, support frame 4, straight tube 5, adpting flange 6, connection
Post 7, arc transition portion 8 etc..
As shown in figure 1, the utility model is a kind of diesel engine gaseous mixture connecting tube, including flange seat 1, the flange
Integrally connected sectorial cavity 2 on seat 1, the other end of sectorial cavity 2 fix cone connection 3, and the outer face of cone connection 3 is consolidated
Surely straight tube 5 is connected, the outer face of straight tube 5 sets adpting flange 6；Pass through arc transition portion 8 between the adpting flange 6 and straight tube 5
Connect, the tube surfaces fixing support rack 4 of the straight tube 5, the both sides that straight tube 5 is corresponded on support frame 4 set a company respectively
Connect post 7.
Be connected with straight tube 5 internal diameter of one end of cone connection 3 is connected one with sectorial cavity 2 less than cone connection 3
The internal diameter at end.
Support frame 4 and the both ends of the surface of the connection of straight tube 5 are arc-shaped transition.
Connecting hole is opened up on flange seat 1 and adpting flange 6, and connecting hole is counterbore.
The course of work of the present utility model is as follows：At work, air and gaseous mixture are via straight tube 5 for the utility model product
Enter in sectorial cavity 2, gas forms vortex in sectorial cavity 2, is advantageous to gas mixing, while cone connection 3 has
There is diffused air, gaseous mixture has certain diverging expansion effect when being entered by straight tube 5 in cone connection 3.
