PE electric smelting inner pipe plug

Abstract

The invention relates to a PE electric smelting inner pipe plug. The PE electric smelting inner pipe plug comprises a pipe plug body, and a separation plate serving as a bottom surface of the pipe plug body to be tightly connected with the pipe plug body. The inner pipe plug further comprises a binding post; the pipe plug body respectively comprises an electric smelting layer and an inner pipe layer from outside to inside; and a heater is arranged in the electric smelting layer, and is connected with the binding post. In the inner pipe plug provided by the invention, as the electric heating layer of the inner pipe plug is heated to return to a molten state, molecules on the contacted surfaces of the inner pipe plug and a buoyancy pipe are wound, and are fused as a whole after being cooled, and the inner pipe plug can be firmly welded in a pipe to achieve a partition effect. The inner pipe plug, provided by the invention, can improve the construction efficiency while guaranteeing the welding quality.

Description

technical field [0001] The invention relates to the field of marine aquaculture, in particular to a PE electrofusion inner pipe plug. Background technique [0002] In the existing marine culture net cage system, partitions need to be arranged between the main buoyancy tubes for segmentation, so as to prevent the net cage system from sinking due to water entering a certain position. The existing construction plan is mainly to embed a PE plate with the same inner diameter as the buoyancy tube into the buoyancy tube, and then use a welding torch to weld the PE plate to fix the PE plate in the buoyancy tube. Sometimes the operation is time-consuming and the quality of welding cannot be guaranteed, so the actual effect can not meet people's expectations. Another construction scheme is to hot-melt butt joint PE pipe fittings with partitions between the buoyancy pipes. However, this construction scheme adds two additional joints, which increases the workload and reduces the overal...

The existing construction plan is mainly to embed a PE plate with the same inner diameter as the buoyancy tube into the buoyancy tube, and then use a welding torch to weld the PE plate to fix the PE plate in the buoyancy tube. The operation is time-consuming and the quality of welding cannot be guaranteed, so the actual effect can not meet people's expectations

Another construction plan is to hot-melt butt joint PE pipe fittings with partitions between the buoyancy pipes. However, this construction plan adds two additional joints, which increases the workload and reduces the overall strength of the cage.
