Water pipe butt joint device for hydropower construction

Abstract

The invention discloses a water pipe butt joint device for hydropower construction. The water pipe butt joint device for hydropower construction comprises a working base, a fixing clamping platform isfixedly and vertically welded at the left end of the upper end face of the working base, a clamping groove is formed in the upper end of the fixing clamping platform, thread holes are formed in the front upper end face and the rear upper end face of the clamping groove, the upper end of the fixing clamping platform is fixedly connected with a first clamp through a locking bolt, a heating workingplatform is arranged at the right end of the fixing clamping platform in parallel, and a semicircle groove coaxial with the clamping groove of the fixing clamping platform is arranged on the upper endface of the heating working platform. The problems of more butt joint defects produced in the hot melting connection are solved through an arranged connecting piece, the butt joint strength is higher, the effect is better, the appearance is attractive, meanwhile, the position accuracy of pipelines is improved on the premise that the firm fixation is guaranteed, and the use value of the water pipebutt joint device is relatively high.

Description

technical field [0001] The invention relates to the technical field of indoor hydropower decoration, in particular to a water pipe butt joint device for hydropower construction. Background technique [0002] Common PE water pipe connection methods include hot-melt connection, electric fusion connection, and steel-plastic flange connection. [0003] Hot-melt butt joint: The hot-melt butt joint of PE water supply pipe uses a hot-melt butt welding machine to heat the pipe end. After the pipe end is melted, it is quickly bonded, and a certain pressure is maintained, and the purpose of fusion is achieved after cooling. [0004] Electrofusion connection: The electrofusion connection of PE water supply pipes is to put the electrofusion pipe fittings on the pipes and pipe fittings, and heat the resistance wire embedded in the inner surface of the electrofusion pipe fittings through the electric fusion welding machine, and the heat generated makes the electrofusion pipe fittings The...

AI Technical Summary

Problems solved by technology

[0007] 1. It is difficult to determine the axis position between the two pipes to be connected;

[0008] 2. Due to the melting of the PE pipe due to thermal melting, the material becomes molten and flows, resulting in irregularities at the interface;

[0009] 3. Due to the hot-melt connection, the materials of the two pipes are re-melted, resulting in gaps in local locations;

[0010] 4. During the clamping process of the pipe, the outer surface of the pipe is damaged due to the tightening force,

[0011] 5. Due to the cohesiveness of the butt joint of the pipeline, the strength of the connection position is reduced and it is easy to break
