Abstract
Description
[0001] technical field
[0002] The invention relates to a water pipe connection structure, in particular to a water pipe connection structure for a low-pressure waterway.
[0003] Background technique
[0004] In the prior art, the common structure of the water pipe connection structure of the waterway is a sealing ring structure, which is similar to a piston structure. This structure has a disadvantage, that is, the concentricity of the two moving parts must be guaranteed, and the dimensional accuracy of the product must be guaranteed. High, and when the sealing ring enters the piston chamber, it will have friction with the end of the cavity, and the surface of the end of the cavity should be smooth, otherwise the sealing ring will be damaged after a long time; the sealing ring in the sealed state The friction resistance is relatively large, which will bring unnecessary load to the main body of the action and affect work efficiency.
