Abstract
The utility model discloses a ball joint for an underground drainage pipe. The joint comprises a ball shell, a ball body, an inserted pin and a gland, wherein the ball body is arranged in the ball shell; the ball shell and the gland are connected in a threaded fit manner; the inserted pin is inserted to a pin hole between the ball shell and the gland in a penetrating manner; an interface matched with connecting pipes is formed at one end of the ball shell, and the other end of the ball shell is ball-shaped; the ball-shaped ball body is matched with the ball shell; a nest groove is formed on the inner surface of the ball body; a nest groove elastic sealing ring is placed in the nest groove; a pit groove is formed on the outer surface of the ball body; an O-shaped sealing ring is arranged in the pit groove; the inner surface of the gland is arc-shaped, and the radian of the arc-shaped surface is the same with that of the inner surface of the ball shell; and the inserted pin adopts an un-dismantle inversely-buckled structure design after being assembled. By using the double characteristics of the ball joint such as rigidity and deflection, the problem that severe foundation settlement or pipeline deformation leads to the angular displacement between the two connecting pipes is solved, and the pipeline is protected at a contain extent.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of buried drain pipe spherical joint.
Background technique
The Placement that existing pipeline is commonly used is socket joint connection, flange connection etc.; Basically all be not deflection of rigidity; There is influence in laying to pipeline, and can not solve because the deflection problem that foundation settlement or pipeline distortion etc. cause forms the destruction to pipeline.
The model utility content
The utility model has overcome shortcoming of the prior art; A kind of buried drain pipe spherical joint with rigidity and amount of deflection double grading is provided, and the utility model is realized through following technological scheme: a kind of buried drain pipe spherical joint comprises spherical shell and spheroid; Spheroid places spherical shell; Also comprise gland, said spherical shell adopts with gland and is threaded, and spheroid is fixed between spherical shell and the gland.
Also be provided with corresponding pin-and-hole between said spherical shell and the gland, this pin-and-hole is interspersed with latch.
Said spherical shell one end is provided with the interface suitable with connecting tube, the other end be with spheroid coincide spherical.
The middle part of said spheroid is provided with the through hole that adapts with the connecting tube external diameter, and the internal surface of this through hole is provided with a nest groove that elastic seal ring is installed, and realizes the sealing between spheroid and the connecting tube through seal ring.
The outer surface of said spheroid and spherical shell internal surface corresponding part are provided with a hole groove, and this hole groove is equipped with O-ring seals, to realize the sealing between spherical shell and the spheroid.
The internal surface of said gland is an arc shaped surface, and the radian of arc shaped surface is identical with the radian of spherical shell internal surface.
Said latch has on-disconnectable reverse buckling type structural design after adopting assembling.
Compared with prior art; The utility model can make to connect has certain rigid; Has good amount of deflection again; Utilize its double grading, solve institute such as because of foundation settlement serious or pipeline distortion and cause the angular displacement problem of two connecting tubes between arriving, pipeline has been played the certain protection effect with rigidity and amount of deflection.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model comprises spherical shell 1, spheroid 2, latch 4, gland 5, and spheroid 2 places spherical shell 1; Spheroid 2 can be that the arbitrary direction of middle mind-set is done 15 ° with interior rotation with the centre of sphere, and spherical shell 1 adopts thread fiting mode to be connected with gland 5, has the reason of two-way rotation owing to screw thread; Spherical shell 1 is with after gland 5 is connected; Latch 4 interts between spherical shell 1 and gland 5, prevents that gland 5 reversings from getting loose, and has on-disconnectable reverse buckling type structural design after this latch 4 adopts assembling.
Spherical shell 1 one ends are provided with the interface suitable with connecting tube, and it is spherical that the other end is.Spheroid 2 is spherical; And match with spherical shell 1, the buried drain pipe spherical joint requires to have sealing, and spheroid 2 internal surfaces respectively are provided with a nest groove; A brood of groove elastic seal ring 6 is placed in this nest groove; Outer surface of spheroid is provided with a hole groove, and an O RunddichtringO 3 is placed on this hole groove, to reach the seal action between spheroid 2 and spherical shell 1, spheroid 2 and the connecting tube 7 respectively.The internal surface of gland is an arc shaped surface, and the radian of arc shaped surface is identical with the radian of spherical shell internal surface, guarantees spheroid spherical shell rotation relatively.
