Abstract
The invention discloses a convenient-to-weld fire pipeline. The convenient-to-weld fire pipeline comprises a pipeline body, a seal baffle is arranged on the inner wall of one end of the pipeline body, the seal baffle and the pipeline body are formed integrally, the end of the seal baffle is in smooth transition with the inner wall of the pipeline body, a tapered pipe with the diameter larger than the outer diameter of the pipeline body is arranged at the other end of the pipeline body, and the inner diameter of a large-diameter end of the tapered pipe is 5-10mm larger than the outer diameter of the pipeline body. The convenient-to-weld fire pipeline has the advantages that convenience in welding of the fire pipeline is achieved, and excellent airtightness of connection portions is kept.
Description
Technical field
Architecture Design material of the present invention, particularly relates to the fire protection pipeline of building body.
Background technique
Because fire protection pipeline is absolutely necessary a part in tall building, the general installation just must carrying out fire protection pipeline in the shaping rear office of building frame, general in order to occupy less space as far as possible, usually fire protection pipeline is arranged on corner place, but due to the limited length of pipeline, pipeline is needed to connect between the layers, the general method of welding that uses is by two sections of welding now, because the end of two pipelines welded mutually is all smooth arc surface, very difficult when making to weld, in time groove is set at weld, also because pipeline is vertically arrange, electric welding is made to there is the phenomenon moved down at groove place, cause welding leakiness.
Summary of the invention
The object of the invention is: a kind of convenient welding is provided and closely knit fire protection pipeline structure can be welded.
In order to achieve the above object, scheme provided by the invention is: be convenient to the fire protection pipeline welded, comprise pipeline monomer, one end of described pipeline monomer is provided with sealed baffle, described sealing baffle and pipeline monomer one-body molded, described sealing baffle is arranged on pipeline monomer inwall, sealing baffle end and the transition of pipeline monomer inner wall smooth, the other end of described pipeline monomer is provided with the conical pipe that diameter is greater than pipeline monomer external diameter, the internal diameter 5 ~ 10mm larger than pipeline monomer external diameter of the bigger diameter end of described conical pipe.
When connecting tube, a pipeline monomer is provided with sealing baffle one end to be connected with one end that another pipeline monomer is provided with conical pipe, sealing baffle exposed portion is made to insert pipeline monomer inner, now there is the space of 5 ~ 10mm between conical pipe and pipeline monomer, as long as this uses submerged arc welding all to be filled up in space, the connection of fire protection pipeline can be completed like this, owing to there being the existence in space, the liquation of submerged arc welding being flowed in space fire protection pipeline is firmly linked together.
Further, in order to prevent sealing baffle long, Cai make grafting process cause baffle plate wiredrawn edge, the length of described sealing baffle is 10 ~ 40mm, makes sealing baffle to be collided with like this and causes wiredrawn edge.
Further, can not connect fire protection pipeline to make conical pipe and produce interference, the external diameter of described conical pipe is less than 2 times of pipeline monomer external diameter.
Accompanying drawing explanation
Fig. 1 is the fractionation structural representation that the embodiment of the present invention is convenient to the fire protection pipeline welded;
Reference numerals list: monomer 1, sealing baffle 2, conical pipe 3, fin 4.
Embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
As shown in Figure 1 for ease of the fire protection pipeline of welding, comprise pipeline monomer 1, one end of pipeline monomer 1 is provided with sealed baffle 2, sealing baffle 2 and pipeline monomer 1 one-body molded, sealing baffle 2 is arranged on pipeline monomer 1 inwall, sealing baffle 2 end and the transition of pipeline monomer 1 inner wall smooth, the other end of pipeline monomer 1 is provided with the conical pipe 3 that diameter is greater than pipeline monomer 1 external diameter, the internal diameter 5 ~ 10mm larger than pipeline monomer 1 external diameter of the bigger diameter end of conical pipe 3.
In order to prevent sealing baffle 2 long, Cai make grafting process cause baffle plate wiredrawn edge, the length of sealing baffle 2 is 10 ~ 40mm, makes sealing baffle 2 to be collided with like this and causes wiredrawn edge.Can not connect fire protection pipeline to make conical pipe 3 and produce interference, the external diameter of conical pipe 3 is less than 2 times of pipeline monomer 1 external diameter.The inwall of described conical pipe is provided with fin 4.Time time needs to carry out melting welding when soldered, make two segment pipe monomers 1 more firm by fin 4.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
