Abstract

The invention discloses a special ductile cast iron wall penetrating pipe. The special ductile cast iron wall penetrating pipe comprises a wall penetrating sleeve which is embedded into a wall body; afixed ring is formed outside the end part of the wall penetrating sleeve; a bell-shaped socket is formed inside the end part of the wall penetrating sleeve; a main pipeline extends into or penetratesthrough the wall penetrating sleeve; a pressing flange corresponding to the socket is arranged on the main pipeline in a sleeving manner; the pressing flange is detachably connected to the fixed ringby using a plurality of bolts; a sealing ring which is matched with the inner wall of the socket is arranged on the main pipeline in the sleeving manner; the outer wall of the sealing ring is a frustum body; and the end part of the pressing flange is extruded at the end part of the sealing ring. According to the special ductile cast iron wall penetrating pipe, the problem that liquid leakage andwater seepage are easily caused after a rubber pipeline penetrates through a wall directly in construction is solved.

Description

technical field [0001] The invention relates to a pipeline assembly device, in particular to a special nodular cast iron wall-piercing pipe. Background technique [0002] During the construction of the rubber hose pipeline, sometimes it is necessary to carry out the wall-penetrating treatment for the rubber hose pipeline. In some special environments, the wall body has a certain vibration intermittently. The pipe wall of the rubber hose pipe in the wall is damaged, which will cause the pipe wall to seep over time, and the wall will easily collapse after the seepage, which will cause danger. Contents of the invention [0003] The purpose of the present invention is to provide a kind of equipment, this special nodular cast iron wall pipe solves the problem that the rubber pipe pipe is easy to leak and seep after directly passing through the wall during construction. [0004] In order to achieve the above object, the present invention provides a special nodular cast iron wal...
