Abstract
The utility model discloses a double-ball compensating joint which comprises a ball body sleeve and a ball body expansion pipe which are sleeved mutually. The ball body sleeve and the ball body expansion pipe extend towards opposite directions to respectively form a spherical sleeve ball surface and a spherical expansion pipe ball surface. Both the ball body sleeve and the ball body expansion pipe are connected with ball shells in a mutual matching way through connecting pieces. One sections of inner cavities of the two ball shells are of a spherical shape matched with the corresponding sleeve ball surface and expansion pipe ball surface. The ball body expansion pipe is arranged in the inner cavity of the ball body sleeve. A second sealing ring is arranged between the ball body expansion pipe and the ball body sleeve. An anti-falling chuck connected with the ball body sleeve is arranged on the ball body expansion pipe. Due to the adoption of the double-ball compensating joint, not only are both the ball body sleeve and the ball body expansion pipe ensured to move relative to the ball shells, and is higher deflection realized, but also the ball body sleeve and the ball body expansion pipe can move relatively, so that the axial compensating effect is achieved. Not only is the sealing performance good and is the deflection improved, but also both the angle compensation and the axial compensation are achieved.
Description
Technical field
The utility model relates to a kind of pipe coupling, and is particularly related to a kind of pair of ball compensating joint.
Background technique
At present; Various pipe-line systems are for example: gas pipe line; Water supply line, oil transport pipelines etc. are applied in the daily life widely, but in the process of deployment of various pipe-line systems, often to consider because surface subsidence is serious, vibrations are big, with a varied topography and seasonal variations and day and night big pipeline deflection that produces of the temperature difference and expand with heat and contract with cold etc. all can pipeline be produced serious influence; General solution is that axial displacement and the deflection angle off-centre that compensating joint remedies pipeline is set in the process of deployment of pipeline; Spherical compensating joint is a kind of joint with large deflection, is ZL 02264646.9 disclosed a kind of spherical compensating joint like the patent No., and this sphere compensating joint can free within the specific limits deflection; But its existence can only be done angle compensation, can not make the shortcoming of nose balance.
The model utility content
The purpose of the utility model is to provide a kind of pair of ball compensating joint, and it has good airproof performance, good amount of deflection, and can do the characteristics that angle compensation again can nose balance.
The purpose of the utility model is to realize through following technological scheme:
A kind of pair of ball compensating joint; It comprises spheroid sleeve pipe and the spheroid telescopic pipe that connects together mutually; Both are extended with sleeve pipe sphere spherical in shape and telescopic pipe sphere round about; Said spheroid sleeve pipe and spheroid telescopic pipe all cooperatively interact through link and are connected with a spherical shell, and one section of said two spherical shell inner chambers is the sphere that matches with corresponding sleeve pipe sphere and telescopic pipe sphere.
Said spheroid telescopic pipe is arranged at the inner chamber of spheroid sleeve pipe, and is provided with seal ring two between said spheroid telescopic pipe and the spheroid sleeve pipe, is provided with the anticreep chuck that connects the spheroid sleeve pipe on the said spheroid telescopic pipe.
Said sleeve pipe sphere and telescopic pipe sphere all are arranged at the inner chamber of spherical shell; One end of said spherical shell all is outward extended with the joining portion; Said joining portion and spherical shell inwall form a step; The end face at said joining portion is connected gland through connecting bolt with the attaching nut, and the cavity shape of said gland cooperates the spherical shell inner chamber to constitute a spherical inner chamber together, and between the end face of said gland and the spherical shell step U RunddichtringO is set.
The beneficial effect of the utility model is that the spheroid sleeve pipe of said pair of ball compensating joint and spheroid telescopic pipe all and between the spherical shell utilize sphere to cooperatively interact, and have both guaranteed that connecting head has enough rigidity; Spheroid sleeve pipe and spheroid telescopic pipe all and between the spherical shell can be relatively moved, guarantee bigger amount of deflection, and also can relatively move between spheroid sleeve pipe and the spheroid telescopic pipe; To reach the nose balance effect; Not only good airproof performance has increased amount of deflection, and can do angle compensation again can nose balance.
