Summary of the invention:
Be to solve the deficiencies in the prior art, the utility model provides a kind of big deflection angle (maximum flexible amount is greater than 30 °) and the eccentric spherical compensating joint of large deflection pine cover, with the demand that satisfies market and the needs of actual engineering.
The utility model is achieved in that the spherical compensating joint of large deflection pine cover, comprise body, two movable short tubes, gland, back-up ring, limiting stopper, seal ring, two movable short tubes with flange are passed in the inside of described body, described flange is positioned at the exterior edge face of short tube, the connecting end of described body both sides is connected with bolt with a gland respectively, it is characterized in that: described body is one section spherical shell that inner chamber is spherical in shape, described short tube forms one section spherical shell that inner chamber is spherical in shape along the interior edge face direction, described body spherical shell diameter is greater than the diameter of short tube spherical shell, the both ends of the surface inboard of described body is separately installed with back-up ring, described shield ring sleeve is connected on the outside of short tube spherical shell, described short tube spherical shell is provided with limiting stopper, between described back-up ring and the gland seal ring is installed, described seal ring is the U RunddichtringO, described seal ring contacts with the outer wall of short tube spherical shell, and its surface of contact is the ball face.
Be provided with one zero type Stamping Steel Ribbon in the described U RunddichtringO.
Described U RunddichtringO two ends internal surface respectively is provided with a jut.
The junction surface of described body and gland is provided with a circle Stamping Steel Ribbon.
On the described flange through hole is set.
The spherical compensating joint of described the utility model large deflection pine cover embeds in the rectangle groove of gland inside.
Can relatively rotate between the body of the spherical compensating joint of the utility model large deflection pine cover and the short tube spherical shell, guarantee that it has certain amount of deflection; The U RunddichtringO is installed between described back-up ring and the gland, the U RunddichtringO utilizes gland to be pressed on the smooth sphere of short tube spherical shell, by the seal ring extrusion, reach the effect of sealing and deflection, has certain amount of deflection simultaneously, this seal style is simple, reliable, in the time of guaranteeing the compensation pipeline takes place in allowing deformation band displacement and do not leak.The maximum flexible amount of the spherical compensating joint of the utility model large deflection pine cover reaches 36 °.
