Description
Technical field
The utility model relates to pipe fitting technical field more particularly to a kind of spigot-and-socket couplings.
Background technique
The utility model patent that number of patent application is 201520055207.9 discloses anti-wear spigot-and-socket coupling, wraps
Include socket and bellmouth, in the socket insertion bellmouth, the socket is equipped with differential, the differential by screw bolt and nut with
Bellmouth edge is fixedly connected, and the inner surface of the bellmouth is equipped with embedded groove, and the embedded groove has been embedded in cushion rubber, the cushion rubber
It is formed and is interference fitted with the jack part of insertion bellmouth.The utility model has the beneficial effects that structure is simple, easy for installation, company
It connects securely.
The coupling of above structure can prevent abrasion to a certain extent but sealing effect is poor, after cushion rubber failure
Sealing effect is just lost completely.
Utility model content
The technical problems to be solved in the utility model is to overcome above-mentioned technical problem to provide one kind and can effectively prevent
It only wears, while sealing effect is good, the convenient spigot-and-socket coupling of grafting.
To solve the above problems, the utility model uses a kind of following technical scheme: spigot-and-socket coupling, including accept
It manages, is plugged with insertion pipe in adapting pipe, ecto-entad is equipped with the first tapered surface, cylindrical surface and the second taper with this in adapting pipe
Face, the periphery of insertion pipe are equipped with the tapered surface cooperated with the second tapered surface, and the periphery of insertion pipe is equipped with twice annular
Slot, is equipped with ring type seal in annular groove, and the outer sheath of insertion pipe is equipped with conical seal ring, the outer surface of conical seal ring and the
The cooperation of one tapered surface, the outer sheath of insertion pipe are equipped with the clamp nut for compressing conical seal ring, clamp nut and adapting pipe
Periphery is threadedly coupled;
Processing of rust removing is passed through in the inner wall of adapting pipe and outside respectively, and surface coats anti-corrosion material；
Processing of rust removing is passed through in the inner wall of insertion pipe and outside respectively, and surface coats anti-corrosion material.
The spigot-and-socket coupling of the utility model by adopting the above technical scheme, can effectively prevent wearing, seal simultaneously
Effect is good, and grafting is convenient.
The technical solution of the utility model is described further with reference to the accompanying drawing.

In figure: 1- adapting pipe；2- insertion pipe；The first tapered surface of 3-；The cylindrical surface 4-；The second tapered surface of 5-；6- annular groove；7-
Ring type seal；8- conical seal ring；9- clamp nut.
Specific embodiment
Embodiment is plugged with insertion pipe in adapting pipe 1 as shown in Figure 1, a kind of spigot-and-socket coupling, including adapting pipe 1
2, ecto-entad is equipped with the first tapered surface 3, cylindrical surface 4 and the second tapered surface 5 with this in adapting pipe 1, on the periphery of insertion pipe 2
Equipped with the tapered surface cooperated with the second tapered surface 5, the periphery of insertion pipe 2 is equipped with twice annular groove 6, is equipped in annular groove 6
The outer sheath of ring type seal 7, insertion pipe 2 is equipped with conical seal ring 8, and the outer surface of conical seal ring 8 is matched with the first tapered surface 3
It closes, the outer sheath of insertion pipe 2 is equipped with the clamp nut 9 for compressing conical seal ring 8, the periphery of clamp nut 9 and adapting pipe 1
It is threadedly coupled.
Processing of rust removing is passed through in the inner wall of adapting pipe 1 and outside respectively, and surface coats anti-corrosion material.
Processing of rust removing is passed through in the inner wall of insertion pipe 2 and outside respectively, and surface coats anti-corrosion material.
Pipe fitting using the above structure is equipped with and the cooperation of the second tapered surface 5, two by the periphery of insertion pipe 2
The sealing of ring type seal 7 and conical seal ring improves sealing effect, in addition, above-mentioned pipe fitting grafting and easy for installation.
