In order to solve the above technical problems, the one side as the utility model, a kind of pipe orifice mechanism is provided, including by
Connectivity port made of stainless steel material in connectivity port, is welded and fixed the connection structure made of copper material, connection structure
Raised end including fixture body and from the formation of fixture body outward flanging, the outer wall of fixture body and the inner wall of connectivity port
Cooperation, the external profile diameter of raised end are less than the external profile diameter of the end of the connectivity port joined together by it..
Further, the wall thickness of fixture body is less than the wall thickness of the connectivity port.
Further, the end face of raised end and connectivity port is compression fit.
Further, the inner wall front end of fixture body is provided with positioning step portion, and nozzle structure passes through positioning step portion reality
Grant the pipeline fitting positioning in flow path.
Further, several convex epireliefs or salient point are provided on the outer wall of fixture body.
Further, connectivity port is fixedly connected with connection structure by default solder progress stove weldering.
Further, the outer wall front end of fixture body is provided with guide surface, in the connectivity port of fixture body cooperation
It is provided with step surface on wall, the receiving portion for accommodating the default solder is constituted between guide surface and step surface.
Further, a kind of muffler, including the ontology made of stainless steel material are provided, ontology is equipped with above-mentioned
Nozzle structure.
The fixture body outward flanging of nozzle connection structure is formed raised end, and raised end and company by the utility model
Port abutting is connect, the quality of connection of nozzle had both been ensure that, and had in turn ensured the simple of technique；And the external profile diameter of raised end is small
The external profile diameter of the end of connectivity port joined together by it, further reduces the contact surface of nozzle structure and air, reduces
It is exposed to the thrashing problems of outer soldering crack band.

Specific implementation mode
The embodiments of the present invention are described in detail below, but the utility model can be defined by the claims
Implement with the multitude of different ways of covering.
It please refers to Fig.1 to shown in Fig. 4, embodiment according to the present utility model, the nozzle structure of the utility model is applied
In reservoir muffler, the ontology 1 being made of stainless steel is offered on ontology 1 and is flowed into for fluid and the company of fluid outflow
Port 11 is connect, at least one connectivity port 11, is welded and fixed connection structure 2 made of copper material, connection knot
Structure 2 include fixture body 21 and from 21 outward flanging of fixture body formed raised end 22, the outer wall 211 of fixture body with
The inner wall 111 of connectivity port 11 coordinates, and the external profile diameter of raised end 22 is less than the end 13 of the connectivity port 12 joined together by it
External profile diameter.
The utility model is to the control of the external profile diameter of raised end in the outer of the end less than the connectivity port joined together by it
Edge diameter further reduces the contact surface of nozzle structure and air, reduces the system for being exposed to outer soldering crack band
Problem of Failure both ensure that the quality of connection of nozzle, in turn ensure the simple of technique.
Preferably, the wall thickness of fixture body 21 is less than the wall thickness of connectivity port 11, it is highly preferred that before the inner wall of fixture body
End is provided with positioning step portion 24, and nozzle structure is implemented to position with pipeline fitting 3 in flow path by positioning step portion 24, can also be
Several convex epireliefs or salient point are provided on the outer wall of fixture body 21 so that the outer wall of fixture body 21 and the inner wall of connectivity port
111 directly constitute clearance space.
Preferably, 13 compression fit of end face of raised end 22 and connectivity port 11, connectivity port 11 are logical with connection structure 2
It crosses default solder progress stove weldering to be fixedly connected, the outer wall front end of fixture body 21 is provided with guide surface 25, with fixture body 21 matches
