The invention relates to a seal ring. The seal ring is of an integral open type ring structure with an inflable inner cavity, the seal ring is provided with an inflating and deflating port communicated with the inflable inner cavity, the two ends of the seal ring are correspondingly provided with a first step structure and a second step structure which are adaptive in shape, the first step structure and the second step structure each are provided with a high step surface and a low step surface, the low step surfaces of the first step structure and the second step structure each are provided with a plug, the high step surfaces of the first step structure and the second step structure each are provided with an insertion groove in corresponding inserted connection with the plug, and after the plug and the insertion groove are in inserted connection, the seal ring forms a closed ring structure. The seal ring is reasonable in design and simple in structure and facilitates dismantling, installation and replacement. The invention further relates to a method for installing the seal ring on a telescopic pipe and a rotating flange. The installation method is simple and easy to operate. The seal ring can be installed and replaced very quickly and conveniently.
Description
technical field [0001] The invention relates to a sealing ring, a telescopic tube and a rotating flange equipped with the sealing ring. Background technique [0002] Inflatable sealing rings have been widely used in various mechanical equipment, but the traditional sealing rings are mostly hollow closed ring structures. In the prior art, such as drainage vehicles, fire trucks and other mechanical equipment that need to extend the pipeline to a designated location, in order to flexibly control the length of the pipeline, it is generally necessary to use a telescopic tube composed of an outer tube and an inner tube. There is a sealing ring between the tube and the inner tube; in addition, the sealing ring is also widely used in rotating equipment with relative rotary motion such as rotating flanges, which are usually sealed with an inflatable sealing ring to make it rotate when it is not inflated, and when inflated When sealed. However, the sealing ring is a vulnerable part ...
