Description

Flange loose sleeve expansion joint

Technical Field

The utility model relates to a loose cover expansion joint equipment technical field of flange, concretely relates to loose cover expansion joint of flange.

Background

The expansion joint is also called as expansion joint, expansion joint and compensator. But the expansion bend is flexible at the axial of certain extent, also can overcome the skew that the different axial of pipeline butt joint produced in certain angle, and the installation and the dismantlement of the valve pipeline of can very big convenience can freely stretch out and draw back in the flexible volume of pipeline permission, in case cross its the biggest flexible volume and just play spacingly, ensure the safe operation of pipeline. Mainly for guaranteeing the safe operation of pipeline, have following effect: compensating the axial, transverse and angular thermal deformation of the absorption pipeline; the vibration of the equipment is absorbed, and the influence of the vibration of the equipment on the pipeline is reduced.

The traditional flange loose expansion joint has the following problems in the actual use process:

1. the connecting pipe is easy to fall off when being loosely connected with the flange.

2. The flange loose sleeve expansion joint has limited expansion amount and poor expansion effect.

To this end, we propose a flange loose expansion joint.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model provides a not enough to prior art, the utility model provides a loose cover expansion joint of flange has overcome the not enough of prior art, reasonable in design, and compact structure has solved the problem that current loose cover expansion joint of flange appears droing easily when connecting, the utility model discloses a simple structure combination is in the same place connecting pipe and the quick joint of flange, has improved the effect of connection, has improved flexible volume through the spring simultaneously, has improved the damping effect, has very strong practicality.

(II) technical scheme

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

a flange loose telescopic joint comprises a flange and a gland, wherein a plurality of studs are inserted between the flange and the gland, nuts are connected to the studs in a threaded manner, a connecting pipe is inserted in the gland in a sliding manner, and the same sealing ring is clamped between the connecting pipe and the flange and between the connecting pipe and the gland;

a plurality of L-shaped rods are arranged in the flange, the other ends of the L-shaped rods are connected with sliding blocks, and the springs are clamped in Z-shaped grooves formed in the connecting pipes in a sliding mode.

Further, a spring is arranged between the L-shaped rod and the connecting pipe.

Further, the number of the L-shaped rods is more than or equal to 2.

Furthermore, a rubber sleeve is sleeved on the sliding block.

(III) advantageous effects

The embodiment of the utility model provides a flange loose tube expansion joint. The method has the following beneficial effects:

1. can improve the connection effect of flange and connecting pipe, peg graft the gland with the connecting pipe in, aim at the sliding block and insert with the Z-slot on the connecting pipe simultaneously, then through rotating the connecting pipe for the sliding block can slide in the Z-slot, guarantees that flange and connecting pipe are difficult to break away from, improves the connection effect.

2. The expansion amount is improved, and the vibration reduction effect is improved. After the connecting pipe is clamped in the Z-shaped groove a in a sliding mode, the effect of the spring is matched, the expansion amount is increased, and the vibration reduction effect is improved.
