Sizing casing pipe cover for PE-pipe cooling water tank

Abstract

The invention relates to a sizing casing pipe cover for a PE-pipe cooling water tank. The sizing casing pipe cover is used for the water feeding side of a sizing casing pipe, wherein the sizing casing pipe comprises a sleeve and a sizing pipe; a plurality of water discharging holes are radially and uniformly distributed on the sizing pipe at intervals; a pipe opening at the end surface of the water feeding side of the sizing pipe extends out of the sleeve; a pipe opening at the end surface of the water discharging side of the sizing pipe is level to a sleeve opening; the end surface of the water feeding side of the sizing pipe is fixedly connected with the sleeve by a fixing ring, and a coaxial gap is reserved between the sizing pipe and the sleeve; the fixing ring is provided with a through hole which is coaxial to the sizing pipe; threads are arranged on the outer wall of the fixing ring; a casing pipe cover is meshed and fixedly arranged on the fixing ring and can close the pipe opening at the end surface of the water feeding side of the sizing pipe; water feeding ports are radially and uniformly distributed on the casing pipe cover at intervals; the pipe opening at the water feeding side of the sizing pipe and the inner wall of the casing pipe cover form a water feeding cavity body; the cavity body communicates with the coaxial gap reserved between the sizing pipe and the sleeve.

Description

technical field [0001] The invention belongs to the field of pipe material production equipment, in particular to a sizing casing cover for a PE pipe cooling water tank. Background technique [0002] In the PE pipe production line, the pipe needs to be cooled and solidified to make it finalized, but the pipe after cooling often has local protrusions on the surface of the pipe, especially there is a certain difference between the roundness of the pipe mouth and the specified size, so it is necessary to adopt a fixed The diameter casing is pre-cooled after the pipe enters the cooling water tank, and the sizing is completed to avoid serious shrinkage of the pipe at the nozzle position during direct cooling. This sizing casing is installed on the water inlet of the cooling water tank. [0003] At present, the commonly used sizing casing is equipped with a cooling water injection port at the nozzle. However, due to long-term use, the nozzle is prone to sedimentation and clogging....

AI Technical Summary

Problems solved by technology

[0003] At present, the more commonly used sizing casing is equipped with a cooling water injection port at the nozzle. However, due to long-term use, the nozzle is prone to sedimentation and clogging. If it is not cleaned in time, the cooling water will not flow smoothly, thus affecting the cooling effect.
