The above problem is urgently to be resolved.
Utility model content
In view of the above technical problems, the utility model provides a kind of pipe connecting piece for pipeline welding, the sealing of pipe connecting piece
Blocking portion outer diameter is greater than the internal diameter of equipment interface, increases the bonding area of pipeline and equipment, improves welding surface and pipeline welds
The stability and leakproofness connect；In the port of pipeline is welded on, annular groove, which treats welded pipe line, has limit fixed function,
Therefore do not need artificial stringent alignment can firm welding, substantially increase welding efficiency, greatly facilitate the welding of pipeline
Work.
To reach above-mentioned purpose, the utility model adopts the following technical solution:
A kind of pipe connecting piece for pipeline welding, for pipeline to be welded on equipment interface, including with equipment interface phase
The pressure connection terminal of connection and the fitting end being connected with pipeline, the pressure connection terminal include protrude into equipment interface fixed part and with set
The sealing blocking portion of standby side wall contact, the fixed part, sealing blocking portion, fitting end are hollow cylindrical, the fitting end
End face inwardly sink to form annular groove, the port of the pipeline and annular groove connect.
Further, the outer diameter of the sealing blocking portion is greater than the internal diameter of equipment interface, and the outer diameter of the fixed part is little
In the internal diameter of equipment interface.
Further, the sealing blocking portion is a circle annular flange of fixed part outer wall protrusion.
Further, the port inner diameter of the pipeline is not less than the internal diameter of annular groove, and the port outside diameter of the pipeline is not
Greater than the outer diameter of annular groove.
Further, the pressure connection terminal of the pipe connecting piece and fitting end are integrally formed.
By adopting the above technical scheme, the utility model has the following technical effect that
1, the sealing blocking portion outer diameter of the pipe connecting piece for pipeline welding of the utility model, pipe connecting piece is greater than equipment interface
Internal diameter, increase the bonding area of pipeline and equipment, improve welding surface and pipeline welding stability and leakproofness；
2, the pipe connecting piece for pipeline welding of the utility model, the annular groove of pipe connecting piece, which treats welded pipe line, has limit
Position fixed function, thus do not need artificial stringent alignment can firm welding, convenient welding, and substantially increase welding efficiency.

Specific embodiment
The utility model is described in further detail with preferred embodiment with reference to the accompanying drawing.
In conjunction with Fig. 1-6, a kind of pipe connecting piece 10 for pipeline welding is wrapped for pipeline to be welded on equipment interface 20
The fitting end 2 for including the pressure connection terminal 1 being connected with equipment interface 20 and being connected with pipeline 30, pressure connection terminal 1 include protruding into equipment to connect
The fixed part 11 of mouth 20 and the sealing blocking portion 12 contacted with equipment side wall 40, fixed part 11, sealing blocking portion 12, fitting end
2 be hollow cylindrical, and the outer diameter of sealing blocking portion 12 is greater than the internal diameter of equipment interface 20, and the outer diameter of fixed part 11, which is not more than, to be set
The internal diameter of standby interface 20；The end face at fitting end 2 inwardly is sunk to be formed, and the internal diameter of 30 port of pipeline is interior not less than annular groove 21
Diameter, the outer diameter of 30 port of pipeline are not more than the outer diameter of annular groove 21, and pipe end and annular groove 21 connect.This is practical
The novel pipe connecting piece 10 for pipeline welding, sealing 12 outer diameter of blocking portion of pipe connecting piece 10 are greater than the internal diameter of equipment interface 20,
The bonding area for increasing pipeline 30 Yu equipment interface improves stability and leakproofness that welding surface and pipeline 30 weld；Pipe
The annular groove 21 of fitting 10, which treats welded pipe line, has fixed position-limiting action, therefore it is i.e. solderable not need artificial stringent alignment
Securely, convenient welding, and substantially increase welding efficiency.
