AI Technical Summary

Technical Problem

The antifreeze device of the existing PE water supply pipe is prone to leakage during connection, poor connection effect, and requires reserved operating space during laying, resulting in the water inside the water supply pipe being easily frozen and has low practicality.

Method used

The design includes a water supply pipe, a first connection member and a second connection member on one side, a connecting groove and a connecting block are heated by heating the connection member so that the connecting block is stuck in the connecting groove for thermal melting connection. At the same time, the outer wall of the water supply pipe is equipped with an aerogel felt layer and a phenolic foam layer for heat insulation, and the buffer ring and buffer layer improve compressive resistance and heat insulation effect.

Benefits of technology

It realizes positioning and efficient connection during connection, avoids leakage, reduces the thermal conductivity of the water supply pipe, prevents water from freezing, and does not require reserved operating space, improving practicality.

Abstract

The utility model discloses an anti-freezing device for a PE (Poly Ethylene) water supply pipe, relates to the technical field of PE water supply pipes, and aims to solve the problems in the prior art that the water supply pipe is easy to leak during connection, the connection effect is poor, an operation space needs to be reserved in advance, air exists in the operation space, water in the water supply pipe is easy to be influenced and frozen, and the like. According to the scheme, the device comprises a water supply pipe, a first connecting piece is arranged on one side of the water supply pipe, a plurality of connecting grooves are formed in one side of the first connecting piece, a second connecting piece is arranged on the side, away from the first connecting piece, of the water supply pipe, a plurality of connecting blocks are arranged on the outer wall of one side of the second connecting piece, and buffer rings are arranged on the outer walls of the two ends of the water supply pipe. Positioning can be carried out during connection, leakage is not prone to occurring after connection, the connection effect is improved, the heat conductivity of the water supply pipe can be reduced, water in the water supply pipe is prevented from being frozen, operation space does not need to be reserved, and practicability is improved.
