All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example 1:
referring to fig. 1 and 2, embodiment 1 of the present application provides a flared socket device for a pipe, where the pipe includes a first pipe 1 and a second pipe 2, the first pipe 1 includes a straight pipe section 10 and a flared section 11 connected to each other, and one end of the second pipe 2 is a plug end 20; as shown in fig. 3, the socket device comprises a lining part 3, the outer wall of the lining part 3 is matched with the inner wall of the flaring section 11, and the inner wall is matched with the outer wall of the plug end 20; when the first pipeline 1 is butted with the second pipeline 2, the outer wall of the lining part 3 is attached to the inner wall of the flaring section 11, and the inserting end 20 is inserted into the lining part 3.
In the correlation technique, the flaring is generally carried out at two ends of two pipes, and then two flaring sections of the two pipes are butted together through a flange or a hoop, but because the polyolefin pipes are flared at high temperature and cooled, the flaring can shrink, so that the size of the flaring is not matched with the size of the flange or the hoop, and the pipes with two flares cannot be butted.
In embodiment 1 of the present application, one end of the first cylindrical pipeline 1 is flared to form a flared section 11, and a straight pipe section 10 and a flared section 11 connected to each other are obtained, the lining member 3 is inserted into the flared section 11 before the flared section 11 is not cooled, because the outer wall of the lining member 3 is matched with the inner wall of the flared section 11, the lining member 3 can be completely attached to the inner wall of the flared section 11 to support the flared section 11, thereby preventing the cooling shrinkage deformation of the flared section 11, and the cooling shrinkage of the flared section 11 can tightly wrap the flared section 11 on the lining member 3, so that the tight connection between the lining member 3 and the flared section 11 is realized, and the lining member 3 cannot be separated from the flared section 11. When the first pipeline 1 is in butt joint with the second pipeline 2, the inserting end 20 of the second pipeline 2 is inserted into the lining member 3, and the inner wall of the lining member 3 is matched with the outer wall of the inserting end 20, so that the second pipeline 2 is inserted into the lining member 3 and cannot be separated from the flared section 11, and the first pipeline 1 is in tight butt joint with the second pipeline 2.
Therefore, the butt joint method of embodiment 1 of the present application is not affected by the cooling shrinkage of the flared section 11, but instead, the flared section 11 can be tightly wrapped on the lining member 3 due to the cooling shrinkage of the flared section 11, so as to achieve tight connection between the lining member 3 and the flared section 11.
Optionally, the lining element 3 is rigid, and the lining element 3 is adapted to be received in the flared section 11 when the flared section 11 is not cooled, so as to resist cooling shrinkage of the flared section 11.
The lining member 3 is inserted into the flared section 11 before the flared section 11 is not cooled, and since the lining member 3 of the embodiment 1 of the present application is rigid, the lining member 3 will not deform along with the contraction of the flared section 11, so that the flared section 11 contracts the lining member 3 without causing the deformation of the lining member 3, and therefore, not only is the tight connection between the lining member 3 and the flared section 11 achieved, but also the size of the lining member 3 will not change.
Preferably, the lining element 3 is made of metal or plastic material.
The lining member 3 is made of metal or plastic with high rigidity and low cost, preferably one of galvanized steel, aluminum, stainless steel, copper, polyvinyl chloride PVC, polypropylene PP, polyethylene PE, and acrylonitrile-butadiene-styrene ABS. The materials have high rigidity, can meet the rigidity requirement of the lining part 3, have low cost and are suitable for mass production.
Optionally, the length of the lining element 3 is matched to the length of the flared section 11.
Because the transition exists between the flaring section 11 and the straight pipe section 10, the lining part 3 can not extend into the transition part, and the manufacturing cost of the lining part 3 can be greatly saved on the basis of not influencing the supporting flaring section 11.
Preferably, the end of the lining element 3 remote from the straight tube section 10 is flush with the end of the flared section 11 remote from the straight tube section 10.
This prevents the end of the flared section 11 remote from the straight tube section 10 from contracting and becoming smaller in internal diameter, hindering the insertion of the spigot end 20 of the second conduit 2.
Further, the outer diameter and the inner diameter of the spigot end 20 are both equal to the outer diameter and the inner diameter of the straight pipe section 10.
The first pipeline 1 and the second pipeline 2 are actually the same pipe, one end is a flared section 11, and the other end is an insertion end 20, so that continuous butt joint of a plurality of pipelines is realized.
Further, the outer surface of the flared section 11 is in a trumpet shape, and the outer diameter of the flared section 11 gradually increases from the end close to the straight pipe section 10 to the end far away from the straight pipe section 10.

In the correlation technique, the flaring is generally carried out at two ends of two pipes, and then two flaring sections of the two pipes are butted together through a flange or a hoop, but because the polyolefin pipes are flared at high temperature and cooled, the flaring can shrink, so that the size of the flaring is not matched with the size of the flange or the hoop, and the pipes with two flares cannot be butted.
In embodiment 2 of the present application, one end of the first cylindrical pipeline 1 is flared to form a flared section 11, and a straight pipe section 10 and a flared section 11 connected to each other are obtained, the lining member 3 is inserted into the flared section 11 before the flared section 11 is not cooled, because the outer wall of the lining member 3 is matched with the inner wall of the flared section 11, the lining member 3 can be completely attached to the inner wall of the flared section 11 to support the flared section 11, thereby preventing the cooling shrinkage deformation of the flared section 11, and the cooling shrinkage of the flared section 11 can tightly wrap the flared section 11 on the lining member 3, so that the tight connection between the lining member 3 and the flared section 11 is realized, and the lining member 3 cannot be separated from the flared section 11. When the first pipeline 1 is in butt joint with the second pipeline 2, the inserting end 20 of the second pipeline 2 is inserted into the lining member 3, and the inner wall of the lining member 3 is matched with the outer wall of the inserting end 20, so that the second pipeline 2 is inserted into the lining member 3 and cannot be separated from the flared section 11, and the first pipeline 1 is in tight butt joint with the second pipeline 2.
Therefore, the butt joint mode of embodiment 2 of the present application is not affected by the cooling shrinkage of the flared section 11, but the flared section 11 can be tightly wrapped on the lining member 3 due to the cooling shrinkage of the flared section 11, so as to realize the tight connection between the lining member 3 and the flared section 11.
Optionally, the lining member 3 of embodiment 2 of the present application is rigid, and the lining member 3 is inserted into the flared section 11 before the flared section 11 is cooled, because the lining member 3 of embodiment 2 of the present application is rigid, the lining member 3 will not deform along with the contraction of the flared section 11, so that the flared section 11 contracts the lining member 3, and the lining member 3 will not deform, so that not only the tight connection between the lining member 3 and the flared section 11 is achieved, but also the size of the lining member 3 will not change.
Furthermore, one end of the insertion end 20 close to the straight pipe section 10 is flush with one end of the lining element 3 close to the straight pipe section 10, and the length of the lining element 3 is equal to that of the insertion end 20.
In actual production, the inserting end 20 can be marked according to the length of the lining piece 3, and when the inserting end 20 is inserted into the lining piece 3, the insertion is stopped until the mark is flush with one end of the flared section 11 far away from the straight pipe section 10, so that the inserting end 20 is prevented from being continuously inserted and abutted against the flared section 11 to damage the flared section 11.
