Title:
PIPELINE QUICK CONNECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/119955
Kind Code:
A1
Abstract:
A pipeline quick connecting device, comprising: a female connecting terminal (1), which is hollow inside, the two ends of the female connecting terminal being opened to form a female pipeline connecting end (113) and a female butt joint end (112), respectively; and a male connecting terminal (2), which is hollow inside, the two ends of the male connecting terminal being opened to form a male pipeline connecting end (215) and a male butt joint end (211), respectively, wherein the male butt joint end is provided opposite to the female butt joint end and is adapted to be selectively inserted into the female butt joint end so as to realize the quick plugging of the male connecting terminal and the female connecting terminal. A female current suppressing ring (114) is formed on the inner side wall of the female connecting terminal so as to divide an internal space of the female connecting terminal into a butt joint chamber and a drainage chamber, and a female current suppressing assembly (13) is arranged in the drainage chamber. According to the pipeline quick connecting device, the quick plugging of the female butt joint terminal and the male butt joint terminal can be realized only by axially shifting a locking sleeve (121), and a flow channel after butt joint can be ensured to have a better sealing effect, so that the convenience of butt joint and disconnection of two pipelines is greatly improved.
