Plastic steel winding pipe butt joint device convenient to disassemble and assemble

Abstract

The invention discloses a plastic steel winding pipe butt joint device convenient to disassemble and assemble. The plastic steel winding pipe butt joint device comprises a first plastic steel windingpipe, a second plastic steel winding pipe, external convex lines, bolt holes, fastening screws and EVA foaming plates; the first plastic steel winding pipe is connected with the second plastic steel winding pipe through a first butt-joint snap ring and a second butt-joint snap ring, and the outer side of the first plastic steel winding pipe and the outer side of the second plastic steel winding pipe are both provided with the external convex lines; the EVA foaming plates adhere to the inner side of the first butt-joint snap ring and the inner side of the second butt-joint snap ring correspondingly; the first butt-joint snap ring and the second butt-joint snap ring are arranged at the joint between the first plastic steel winding pipe and the second plastic steel winding pipe in a sleevingmode, and the two ends of the first butt-joint snap ring and the two ends of the second butt-joint snap ring are provided with connection blocks; and the connection blocks are provided with the bolt holes. Through the plastic steel winding pipe butt joint device convenient to disassemble and assemble, leakage of the joint between the first plastic steel winding pipe and the second plastic steel winding pipe can be avoided.

Description

technical field [0001] The invention relates to the technical field of plastic-steel winding pipes, in particular to a butt joint device for plastic-steel winding pipes that is easy to assemble and disassemble. Background technique [0002] Winding pipe is a kind of pipe made of high-density polyethylene (HDPE) and formed by winding and welding. Because winding pipe has unique environmental protection functions that other pipes do not have, it is often used in various pipelines. It provides great help for pollution prevention, and stainless steel clamps are commonly used to connect the winding pipes. [0003] However, when the existing winding pipes are connected by stainless steel clamps, it is easy to cause leakage at the interface between the two winding pipes, which not only increases the maintenance cost, but also brings maintenance difficulties to the maintenance personnel, which is not conducive to the connection between the two winding pipes. close contact.
