Abstract
The invention discloses an anti-explosion and high-pressure-resisting rotation compensator. The anti-explosion and high-pressure-resisting rotation compensator comprises a different-diameter outer pipe, a rotation inner pipe, an outer casing pipe, a gland and an anti-explosion pipe. The left segment of the outer wall of the rotation inner pipe is provided with an outer protruding shoulder, and an inner protruding shoulder is arranged in the middle of an inner hole of the outer casing pipe. The outer casing pipe is arranged on the rotation inner pipe from right to left in a sleeved mode to form a first sealing cavity and a second sealing cavity. An elastic self-sealing structure is arranged in the second sealing cavity, and the rotation inner pipe is an axial step type structure of which the diameter is gradually reduced from the outer protruding shoulder to the right side. The diameter of the matched position of the rotation inner pipe and the anti-explosion pipe is smaller than the diameter of the matched position between the rotation inner pipe and the gland. Bushings are arranged at the matched position of the rotation inner pipe and the inner protruding shoulder of the outer casing pipe and at the matched position of the rotation inner pipe and the matched position of the rotation inner pipe and the anti-explosion pipe. A rolling support is adopted. The two sides of a sealing ring in the first sealing cavity are provided with metal antifriction rings. According to the anti-explosion and high-pressure-resisting rotation compensator, an anti-explosion structure is simplified, production cost is effectively reduced, operation is flexible, and the anti-explosion and high-pressure-resisting rotation compensator is resistant to high pressure and durable and reliable in sealing.
