Of course, in some embodiments, other values may be selected according to the thickness and width of the strap 11 and the diameter of each slit in the mesh enclosure 1 without departing from the scope of the present invention.

In addition, the mesh enclosure 1 is a strip mesh enclosure 1, and each strip 11 of the mesh enclosure 1 forms a preset included angle with a direction perpendicular to the length direction of the mesh enclosure 1.

The utility model discloses embodiment is for prior art, the inventor discovers for the life of extension compensator, when the adoption was mixed with thin wire net and is woven into the metal gauze in the gauze, and too thin metal gauze prevents that the puncture performance is poor, in case is punctureed, leads to leaking in a large number like the same way, and too thick wire net is flexible poor, and elastic deformation is little, unable compensation displacement with alleviate vibrations. The inventors have found that when the mesh enclosure 1 is woven by using the metal flexible strips 11, the piercing resistance is remarkably improved because the strips 11 are flat with a certain width. And because the mesh enclosure is woven by the flexible strips 11, the mesh enclosure 1 has high flexibility and large elastic deformation, and can effectively compensate displacement and relieve vibration. Therefore, the service life of the compensator can be prolonged obviously after the mesh enclosure 1 in the application on the premise of ensuring the compensation performance of the compensator. Further, since the net cover 1 is formed by weaving the strip 11, the net cover 1 has a small number of meshes, and even if the material inside the net cover 1 is aged and broken, a large amount of leakage does not occur.
