Abstract
The invention relates to an air valve joint for protecting a micro-cable, and belongs to the technical field of optical cable equipment. In the air valve joint, the upper end of a lower outer sleeve extends into the lower end of an upper outer sleeve to be in interference fit with the lower end of the upper outer sleeve; a pipe head is inserted into a pipe head clamping base so as to form a pipe head assembly; the pipe head assembly is divided into upper and lower groups; an upper pipe head assembly, a spring ring, a gasket, a seal ring and an air valve are arranged in the upper outer sleeve coaxially; a lower pipe head assembly, the spring ring and the like are arranged in the lower outer sleeve coaxially and symmetrically; and an air valve control handle is sleeved on the outer wall of the part of sleeving the lower outer sleeve and the upper outer sleeve mutually. In the air valve joint, an air course in a micropipe can be opened or closed; when the optical fibers are blown into the micropipe, the air valve is opened; and after the optical fibers are blown into the micropipe, the air valve is closed, so that the outer wall of a hole in the air valve clings to the optical fibers to ensure that the inside of the micropipe does not leak air. Therefore, the sealing property in the micropipe is excellent, the micropipe is difficult to flatten, the optical fibers in the micropipe are protected against damage, and the service life of the micropipe and the optical fibers in the micropipe is improved.
