Further, described shoulder offering fixing groove, protecting against shock pad is fixed in fixing groove.
Further, on described protecting against shock pad, the relevant position on the end face of bellmouth end is carved with in advance and is easy to locating cone
That inserts splits groove.
Further, on described receptacle wall, circumference offers seal groove, is fixed with sealing ring, at sealing ring in seal groove
External diameter when free state is more than bellmouth internal diameter.
Further, described pipe fitting inner wall is provided with overcoat, and socket inwall is also equipped with overcoat.
Further, described overcoat is made up of corrosion-proof plastic-coated material.
Further, described overcoat is made up of stainless steel material.
During in order to overcome existing socket fitting to connect into pipeline, socket inserts the bad assurance of the degree of depth of bellmouth, easily occurs
Collide bottom socket end and bellmouth, and then cause generation abrasion bottom socket end and bellmouth to even result in anticorrosive coat destruction
Defect, the bellmouth inwall in this protecting against shock pipe joint structure and pipe fitting inner wall transition position are provided with flat annular shoulder, shoulder
On be provided with protecting against shock pad, even if so during grafting, socket inserted deeply, colliding with socket end contacts also
Be not rigidity, lack bottom the bellmouth of buffering, but flexibility that there is the protecting against shock pad of comfort cushioning performance, this it is avoided that
The destruction directly collided bottom socket end and bellmouth and bring, serves protection pipe fitting inner wall and the work of anticorrosive coat
With, it is ensured that the normal service life of pipeline；Match with protecting against shock mat structure simultaneously, socket end face be fixed with locating cone,
During grafting, locating cone is inserted in protecting against shock pad and position, the stability that socket joint connects can be increased, it is also possible to eliminate
When socket inserts deep, protecting against shock pad was to the outside elastic force effect of socket；In addition this structure simplifies grafting construction requirement, therefore energy
Improve pipe fitting connection speed to a certain extent, and then reach to improve construction speed, reduction of erection time, save the mesh of construction cost
