Title: BUILT-IN SEALED CONNECTION UNIT, ASSEMBLY AND PIPELINE SYSTEM
Abstract:
Disclosed are a built-in sealed connection unit, an assembly and a pipeline system. The built-in sealed connection unit comprises: a first pipe (110), a connecting pipe (200) and a first connecting member (310); a circumferential surface of the first pipe (110) extends outwardly in the radial direction of the first pipe (110) to form a first baffle (111); the first baffle (111) divides the first pipe (110) into an inward extension section (101) and a mounting section (102); the first connecting member (310) is sleeved onto the mounting section (102) of the first pipe (110) along a direction from the mounting section (102) to the inward extension section (101), being fixedly connected to the mounting section (102); a sealing member is disposed between the first connecting member (310) and the first baffle (111); the connecting pipe (200) is sleeved onto the first connecting member (310) along a direction from the inward extension section (101) to the mounting section (102), being fixedly connected to the first connecting member (310). By means of the present invention, the first pipe (110) and the connecting pipe (200) may be conveniently and quickly connected, and the costs are low.
