Abstract
The present invention relates to a ball-type union. It adopts the ball as turning component, and said invented ball union is formed from union steeve, union body, ball, retainer ring, internal lock nut, external lock nut and sealing component. Said invention also provides the assembly method of all the above-mentioned components and concrete assembly steps.
Description
Technical field
The present invention relates to pipeline connecting device, particularly a kind of ball type loose joint.
Background technique
At present, in the pipeline field, existing coupling arrangement solves not so difficult the accomplishing of sealing problem of connection place, but when requiring connection pipe fitting to have rotating function simultaneously, both take into account has certain difficulty.So existing coupling arrangement can't be accomplished to take into account sealing and turning quality with simple structure, not only flexibility is relatively poor, and makes troubles for easily fitting operation or use.
Summary of the invention
Ball type loose joint of the present invention technical problem to be solved is: existing pipe fitting coupling arrangement will satisfy when having good sealing and rotating function simultaneously, and both take into account has certain difficulty.So existing coupling arrangement can't be accomplished to take into account sealing and turning quality with simple structure, not only flexibility is relatively poor, and makes troubles for easily fitting operation or use.
Ball movable joint head of the present invention is to solve the problems of the technologies described above the technological scheme that is adopted to be: but realize the turning quality of joint by the mode that ball is set in pipe coupling, and adopt the Sealing of vertical and horizontal to realize the sealing of joint.Ball type loose joint of the present invention is by joints sleeve, fittings body, and ball, back-up ring, interior locking nut and outer locking nut constitute.One of described fittings body is arranged on described joints sleeve inside, described back-up ring is arranged on the described fittings body, convex shoulder on back-up ring and the fittings body forms a ball grooves, described ball is arranged in the ball grooves, be provided with Sealing in described joints sleeve inside with fittings body head contacting point, described back-up ring Internal and external cycle and fittings body and adaptor cup jointing synapsis are provided with Sealing, to realize sealing, locking nut is spun on and compresses back-up ring on the fittings body in described, compresses interior locking nut in the described outer locking nut precession joints sleeve.
Working principle of the present invention is: the mode that adopts inside and outside locking nut that joints sleeve and fittings body tightening are connected, and the rolling by ball, not only realize the sealed attachment of joint, and make joint have the function of flexible rotation.
Ball type loose joint of the present invention is applicable to chemical industry, light industry, and medicine, food, industry such as daily, it is little, simple in structure to have a volume, rotates flexibly, uses characteristics such as reliable.
Description of drawings
Fig. 1 is the structural representation of ball type loose joint of the present invention.
The present invention is further described below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, ball type loose joint of the present invention is by joints sleeve 1, fittings body 7, and ball 3, back-up ring 4, interior locking nut 6 and outer locking nut 5 constitute.7 one of described fittings bodies are arranged on described joints sleeve 1 inside, described back-up ring 4 is arranged on the described fittings body 7, convex shoulder on back-up ring 4 and the fittings body 7 forms a ball grooves, described ball 3 is arranged in the ball grooves, be provided with Sealing 2 in described joints sleeve 1 inside with fittings body 7 head contacting points, described back-up ring 4 Internal and external cycles and fittings body 7 and joints sleeve 1 contacting point are provided with Sealing 2, to realize sealing, locking nut 6 is spun on and compresses back-up ring 4 on the fittings body 7 in described, locking nut 6 in compressing in the described outer locking nut 5 precession joints sleeves 1.During installation, swivel cover 1 or fittings body 7 are because there is ball 3 to roll in ball grooves, so not only rotational resistance is little, and flexible, after adjusting to correct position, by interior locking nut 6 locking back-up ring 4 and balls 3, using outer locking nut 5 lock-on connections cover 1 and fittings body 7.
Ball type loose joint of the present invention and prior art contrast, because adopt ball as rotary component, have simplified the structure of coupling arrangement, have function free to rotate when installing simultaneously, are applicable to multiple industry, have purposes and Practical significance quite flexibly.
Claims (3)
1, a kind of ball type loose joint, by joints sleeve, fittings body, ball, back-up ring, interior locking nut, outer locking nut and Sealing constitute, and it is characterized in that: one of described fittings body is arranged on described joints sleeve inside, is provided with a convex shoulder on described fittings body, described back-up ring is arranged on the described fittings body, and described ball is arranged in the middle of convex shoulder and the back-up ring.
2, a kind of ball type loose joint according to claim 1 is characterized in that: locking nut is arranged on the fittings body in described, and is positioned at the back-up ring outside.
