(II) technical scheme

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

a compensation joint capable of improving a sealing effect comprises two symmetrical flanges, connecting pipes are inserted into the two flanges, a sleeve is arranged between the two flanges, and the sleeve is sleeved at the connecting position of the two connecting pipes;

be connected with sealing device on telescopic inner wall, sealing device includes the gas storage ring, all through connection has the rubber ring on the both ends lateral wall of gas storage ring, and it has the inflating valve to link up the grafting on the lateral wall of gas storage ring, and the inflating valve passes telescopic lateral wall and extends to outside the sleeve.

Furthermore, the same piston ring is connected between the flange and the connecting pipe and between the flange and the sleeve.

Furthermore, a sealing ring is arranged at the joint of the inflating valve and the sleeve.

Furthermore, a spring framework is arranged in the rubber ring.

Furthermore, a plurality of screw rods are inserted into the two flanges, and two nuts used for limiting are sleeved on the screw rods in a threaded manner.

(III) advantageous effects

The embodiment of the utility model provides a can improve compensation joint of sealed effect. The method has the following beneficial effects:

1. the sealing effect is improved. Can improve sealed effect through the piston ring, can also play certain buffering effect simultaneously, can aerify in to the gas storage ring through the inflating valve, the inflating valve is aerifyd in to two rubber ring simultaneously, and the rubber ring expands immediately to contradict two connecting pipes, along with the volume increase of aerifing, improve the connection effect of rubber ring and connecting pipe, improve sealing performance.

2. The anti-buffering effect is improved. The rubber ring is inflated to have certain elasticity, can play certain buffering effect, prevents that two pipelines from colliding when flexible and damaging.
