[0029] In this embodiment, one end of the observation pipe 310 is connected to the pipeline body 100, and the other end of the observation pipe 310 is provided with an observation window. The extension line of the observation pipe 310 intersects with the check valve 210 inside the pipeline body 100. Therefore, the working status of the check valve 210 inside the pipeline body 100 and the condition of its components (spring, valve disc, etc.) can be observed at any time through the observation window, allowing for timely detection of problems with the check valve 210 and ensuring the safe operation of the pipeline system.

[0032] Optionally, in some embodiments, the observation assembly 300 further includes a first mounting assembly 330, through which the sealing member 320 is connected to the observation conduit 310.
