Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline prefabricated parts, in particular to a prefabricated part for pipelines passing through walls. Background Art

[0002] Traditional pipe penetration technology typically involves pre-drilling holes and then installing the pipes in them. However, this traditional method presents challenges such as difficult installation and poor sealing. During installation, the pipes can easily shift, leading to unstable installation. Furthermore, the poor sealing of the pre-drilled holes allows for the intrusion of impurities such as moisture and dust, impacting the normal operation of the piping system. Utility Model Content

[0003] The purpose of the utility model is to provide a prefabricated part for pipe wall penetration in order to solve the problems of difficult installation, poor sealing, unstable installation, etc. in common pipe wall penetration.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions: it includes an embedded frame, both ends of the embedded frame are provided with installation grooves, and sealing plates are embedded in the two installation grooves. Three through holes are penetrated by the sealing plate, and protective tubes are provided in the through holes. A limiting protrusion is provided on the inner wall of the sealing plate, and an annular limiting block is fixedly provided on the outer side of the protective tube. The annular limiting block is located between the two limiting protrusions and is fitly connected. Flat platforms are provided on both sides of the annular limiting block, and the two flat platforms between two adjacent annular limiting blocks are fitly connected.

[0005] Furthermore, the installation groove and the contact surface of the sealing plate are both provided with a circular arc groove, and a rubber sealing ring is sandwiched in the arc groove.

[0006] Furthermore, a circular through hole connected to the through hole is provided in the middle of the limiting protrusion, and the protective tube is inserted into the inner side of the circular through hole.

[0007] Furthermore, fastening nuts are embedded at the four corners of the installation slot and are connected by snap fasteners, and the sealing plate is connected to the fastening nuts by screws.

[0008] Furthermore, reinforcement plates are fixedly provided on both sides of the embedded frame.

[0009] Beneficial effects: The utility model has reasonable design and has the following beneficial effects:

[0010] 1. In the solution of the utility model, by providing installation grooves at both ends of the embedded frame and embedding sealing plates in the installation grooves, the problems of difficult installation and poor sealing when the pipe passes through the wall in the prior art are effectively solved. The pipe can be passed through the wall by passing the pipe through the protective pipe. The protective pipe is stabilized by the annular limit block and the flat table provided on the outside to prevent the protective pipe from moving randomly and causing unstable installation. At the same time, the pipe can be effectively limited and protected, greatly improving the installation efficiency and safety.

[0011] 2. In the present invention, a circular arc groove is provided on the contact surface between the installation groove and the sealing plate, and a rubber sealing ring is sandwiched in the arc groove. This structural design significantly improves the sealing performance of the prefabricated component, effectively preventing the intrusion of impurities such as moisture and dust, and ensuring the normal operation of the piping system.

[0012] 3. In the solution of the utility model, reinforcement plates are fixed on both sides of the embedded frame, which further enhances the load-bearing capacity of the embedded frame, allowing the pipeline to withstand a greater load when passing through the wall, meeting the use requirements of high-rise buildings, large facilities and other occasions.
