Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a two ball compensation joint, includes two ball joint portions 1 that the symmetry set up, through the 2 looks spiro union of swivel nut between two ball joint portions 1 for adjust the interval between two ball joint portions 1, be provided with the filter assembly 3 that can dismantle the change simultaneously in the centre of swivel nut 2, be used for filtering the material that flows through between two ball joint portions 1.

Through the double-end compensation joint direct adjustment with original fixed form for by the distance between two ball joint portion 1 that adjusts through swivel nut 2, accessible directly rotates swivel nut 2 and goes on pulling open or reducing of interval between the pipeline section 13 of two ball joint portion 1 like this, and then adjust double-end compensation joint's total length, make the interval between two pipelines of adaptation difference that can be more convenient, this kind of setting makes the simple and easy-to-understand convenience of whole use simultaneously, set up detachable filter assembly 3 in swivel nut 2 simultaneously, be used for carrying out simple filtration to the material through between two ball joint portion 1, and then filtered the material in two pipelines, realized the simple processing to the material, avoid leading to containing impurity in the material in processing or the transportation, influence the use of material.

Each ball joint part 1 consists of a ball sleeve 11 and a ball head pipe 12, the ball sleeve 11 comprises a ball sleeve part 14, the ball head pipe 12 comprises a pipe section 13 and a ball head part 15, and the ball sleeve 11 is sleeved outside the ball head part 15 of the ball head pipe 12 through the ball sleeve part 14 and used for adjusting the angle between the ball sleeve 11 and the ball head pipe 12.

Connect through swivel nut 2 two ball joint portion 1 and form a whole to swivel nut 2 is connected the pipeline section 13 of bulb pipe 12 on each ball joint portion 1, and then two bulb pipes 12 are located the centre, and two ball sleeve pipes 11 are located both sides, thereby can carry out the regulation of angle through the angle of rotating ball sleeve pipe 11 on bulb pipe 12 to the pipeline of two ball sleeve pipe 11 end face connections in both ends.

The outer wall of the pipe section 13 is provided with external threads 131, and the external threads 131 between the pipe sections 13 of the two ball head pipes 12 are opposite and are matched and screwed with the internal threads of the screw sleeve 2.

The inner wall of the screw sleeve 2 is also provided with two groups of symmetrical internal threads with opposite screw directions, and the two internal threads are respectively screwed with the external threads 131 on the two pipe sections 13, so that when the screw sleeve 2 is rotated, the pipe sections 13 on the two ball head pipes 12 at the two ends can be synchronously closed towards the middle or separated towards the two ends, and further, the distance between the two ball head pipes 12 is increased or reduced.

A circle of ring groove 21 is formed in the axial middle point of the inner wall of the screw sleeve 2, and the filtering component 3 is a circular filtering net and is fixedly inserted into the ring groove 21.

The inside of swivel nut 2 is provided with round annular 21 so that when the netted filtering component 3 of circular filtration inserts inside, can be by its spacing fixed to carry out the interception to the material through swivel nut 2 is filtered, and then filters the material that flows in the pipeline that two ball compensation joints in front and back and each ball joint portion 1 correspond.

A semicircular insertion groove 22 is formed in the outer wall of the screw sleeve 2 corresponding to the annular groove 21 and used for inserting the filter assembly 3.

The semicircular insertion groove 22 is formed in the position, corresponding to the annular groove 21, of the outer wall of the threaded sleeve 2, and the filter plate assembly is in a circular filter net shape, so that when the filter assembly 3 is inserted into the annular groove 21 on the inner side of the threaded sleeve 2, a groove for inserting the filter assembly into the annular groove 21 is needed, the groove is communicated with the annular groove 21, the filter assembly 3 can be directly inserted into the annular groove 21 conveniently, and the filtering of materials passing through the threaded sleeve 2 is completed.

The insert 2 has a receiving cavity 23 formed in the other half of the inner wall corresponding to the insertion groove 22, and a blocking ring 24 that is slidable is received in the receiving cavity 23 to close the insertion groove 22.

In the present embodiment, a receiving groove is formed in a portion of the thread insert 2, which is not provided with the insertion groove 22, at the other half thereof for receiving the barrier replacement piece, so that when the barrier ring piece 24 is pulled into the receiving groove, a space of the insertion groove 22 is made available, so that the filter assembly 3 can be inserted into the annular groove 21 of the thread insert 2 from the insertion groove 22, whereas when the barrier ring piece 24 is pulled out from the receiving groove, the barrier ring piece 24 blocks the filter assembly 3 inserted into the annular groove 21 at the insertion groove 22 to prevent the separation thereof.

The utility model discloses a theory of operation and use flow: when the utility model is installed, the end face of the ball sleeve 11 of one of the ball joint parts 1 is butted with the end face of the pipeline, and the two are fixed in a flange connection mode, then the screw sleeve 2 is rotated on the pipe section 13 between the ball head pipes 12 of the two ball joint parts 1 by rotating the screw sleeve 2, so that the screw sleeve 2 is screwed and rotated at the external thread 131 of the two pipe sections 13 to drive the two pipe sections 13 to move towards both ends or draw towards the middle, thereby pushing the space between the two pipe sections 13 to pull open or pulling the space between the two pipelines to reduce, increasing the space between the two ball joint parts 1 or reducing the space between the two ball joint parts 1, adjusting the angle between the ball sleeve part 14 and the ball head part 15 in the two ball joint parts 1 simultaneously until the end face of the ball sleeve 11 of the other ball joint part 1 is butted with the end face of the other pipeline, and the two are fixed in a flange force connection mode, so that the purpose of connecting the two pipelines through the double-ball compensation joint is fulfilled.

And then the blocking ring sheet 24 can be shifted to be collected into the containing cavity 23 to make room for the space of the insertion groove 22, the filter assembly 3 is inserted into the annular groove 21 of the screw sleeve 2 from the insertion groove 22 to finish the primary limiting of the filter assembly 3, then the blocking ring is shifted reversely, the blocking ring is pulled out from the containing cavity 23 and moved into the insertion groove 22, the insertion groove 22 is sealed, meanwhile, the filter assembly 3 is shielded, and the separation of the filter assembly 3 is avoided.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
