Description

Sleeve spigot and socket type compensator

Technical field

The utility model relates to field of engineering components, is specifically related to a kind of sleeve spigot and socket type compensator.

Background technique

There are a large amount of gas, liquid and solid material need to adopt pipeline to carry in industries such as food, building materials, iron and steel, post and telecommunications and coals, particularly food and steel industry systematic comparison are many, pipeline is also very long, the conveyance conduit temperature of arranging in the workshop is high, conveyance conduit can because the heat expansion distortion causes the transporting system fault, produce certain negative effect to the normal operation of producing.The pipeline compensator that prior art adopts can't solve the indeclinable problem of holding tube road shape, also can't guarantee particularly passing through smoothly of solid material of material.

Summary of the invention

Problem to be solved in the utility model has provided a kind of sleeve spigot and socket type compensator, can solve can't the holding tube road shape not change and can't guarantee the particularly problem passed through smoothly of solid material of material.

The utility model is achieved through the following technical solutions: a kind of sleeve spigot and socket type compensator comprises the first inner tube, the second inner tube, sleeve pipe, bellows and seal arrangement; Be fixedly connected with by seal arrangement in one port of the one end insertion bellows of described sleeve pipe; Described the first inner tube is inserted from the another port of sleeve pipe, and is fixedly connected with this port; After described the second inner tube is inserted from the another port of bellows, pass bellows and be connected with the first inner tube in the threading again, described the second inner tube is fixedly connected with by seal arrangement with the another port of bellows.

The further improvement of the utility model scheme is that the external diameter of the first inner tube and the second inner tube equates with the internal diameter of sleeve pipe.

The further improvement of the utility model scheme is that the connecting end of the first inner tube and the second inner tube is provided with the socket fitting type structure combination; Both connect by mutual socket joint.

The further improvement of the utility model scheme is that the first inner tube and the second inner tube connecting end are provided with the expansion buffer gap.

The further improvement of the utility model scheme is that socket fitting type structure is combined as groove and the corresponding protruding tooth that is uniformly distributed in the first inner tube and the second inner tube connecting end.

The further improvement of the utility model scheme is that the external port of the first inner tube and sleeve pipe is for being welded to connect.

The further improvement of the utility model scheme is that seal arrangement is made of clip, seal ring and bolt; Described seal ring is separately positioned between the junction surface of bellows and sleeve pipe, and between the junction surface of bellows and the second inner tube; Described clip is arranged on bellows outer wall corresponding to seal ring, and with bolton.

The further improvement of the utility model scheme is that the material of the first inner tube, the second inner tube and sleeve pipe is identical.

The utility model is compared with existing technology and has the following advantages:

1, under the prerequisite that guarantees sealing, concentricity and the motion track of control inner tube guarantee that each pipeline that forms inner tube only moves at axial direction, does not change the shape of pipeline;

2,By adopting two axially movable inner tubes to form pipeline, on the basis that solves the compensation of pipeline problem, particularly solid material is mobile smooth and easy in pipeline can to make material;

3,Relatively simple for structure, easy for installation, cost is low, using effect good.

Embodiment

As shown in Figure 1, a kind of sleeve spigot and socket type compensator comprises the first inner tube 1, the second inner tube 2, sleeve pipe 3, bellows 4 and seal arrangement 9; Be fixedly connected with by seal arrangement 9 in one port of the one end insertion bellows 4 of described sleeve pipe 3; Described the first inner tube 1 is inserted from the another port of sleeve pipe 3, and is fixedly connected with this port; After described the second inner tube 2 is inserted from the another port of bellows 4, pass bellows 4 and be connected with the first inner tube 1 in the threading 3 again, described the second inner tube 2 is fixedly connected with by seal arrangement 9 with the another port of bellows 4.

As shown in Figure 1, the external diameter of the first inner tube 1 and the second inner tube 2 equates with the internal diameter of sleeve pipe 3.

As shown in Figure 1, the connecting end of the first inner tube 1 and the second inner tube 2 is provided with socket fitting type structure combination 8; Both connect by mutual socket joint.

As shown in Figure 1, the first inner tube 1 and the second inner tube 2 connecting ends are provided with expansion buffer gap 11.

As illustrated in fig. 1 and 2, socket fitting type structure combination 8 for the groove 10 that is uniformly distributed in the first inner tube 1 and the second inner tube 2 connecting ends and corresponding protruding tooth 10 '.

As shown in Figure 1, the external port of the first inner tube 1 and sleeve pipe 3 is for being welded to connect.

As shown in Figure 1, seal arrangement 9 is made of clip 5, seal ring 6 and bolt 7; Described seal ring 6 is separately positioned between the junction surface of bellows 4 and sleeve pipe 3, and between the junction surface of bellows 4 and the second inner tube 2; Described clip 5 is arranged on bellows 4 outer walls of seal ring 6 correspondences, and fastening with bolt 7.

The first inner tube 1, the second inner tube 2 are identical with the material of sleeve pipe 3.

The external diameter of the first inner tube 1 and the second inner tube 2 equates with the internal diameter of sleeve pipe 3, and namely sleeve pipe 3 has limited the space that moves radially of the first inner tube 1 and the second inner tube 2; The first inner tube 1, the second inner tube 2 are identical with the material of sleeve pipe 3, and namely the expanded by heating coefficient equates; Expansion buffer gap 11 between the first inner tube 1 and the second inner tube 2 is slightly larger than the actual axle of pipeline generation in the production to swell value.When the pipeline expanded by heating, the first inner tube 1 and the second inner tube 2 have the restriction of sleeve pipe 3, and the each other restriction of bell and spigot frame, and relative displacement radially can not occur; And the first inner tube 1 and the second inner tube 2 axial contacts can be avoided in expansion buffer gap 11, thereby can not produce axial deformation; The axial expansion power of sleeve pipe 3 acts directly on bellows 4 two ends, so that sleeve pipe 3 is not axially can stress deformation.
