Plastic pipe interface device

Abstract

The invention discloses a plastic pipe interface device, and belongs to the technical field of plastic pipe pipeline-butting equipment. The plastic pipe interface device mainly comprises a flaring device for flaring the end of the plastic pipe into a horn-shaped opening and a connecting device for clamping and connecting horn-shaped openings. The flaring device comprises a flaring inner body and a flaring outer body which are connected together; a horn-shaped cavity is formed between the flaring inner body and the flaring outer body; and the periphery of the horn-shaped cavity is provided with an inner heating element disposed on the flaring inner body and an outer heating element disposed on the flaring outer body. The connecting device comprises a coupling collar and a connector; the horn-shaped openings of two plastic pipes are compressed tightly by using the connector and the coupling collar; and then two flange coupling ends are connected together oppositely. The plastic pipe interface device can not only guarantee that flow rate of the butting pipe is not influenced but also guarantee that the butting part bear enough big radial impact and axial impact. The plastic pipe interface device is widely applied in plastic pipe butting.

Description

technical field [0001] The invention relates to a plastic pipe interface device, which belongs to the technical field of plastic pipe butt joint equipment. Background technique [0002] In the pipeline transportation industry with slightly higher pressure, such as the high-pressure cleaner industry, plastic pipelines are widely used because of their high pressure resistance, corrosion resistance and low cost. However, as the butt joint between pipelines, the electric melting sleeve connection is mainly used at present, and the connection joints of this connection method have the defects of low strength, high cost, slow construction, and non-detachable. [0003] The majority of plastic pipe manufacturers and scientific researchers have also realized the problem of plastic pipe interface, have been looking for better measures and solutions, and have carried out a lot of research and technological innovation. [0004] For example, Chinese utility model patent ZL95225570.7 disc...

Problems solved by technology

However, there are still some defects. For example, because the end of the plastic pipe itself is a cylindrical structure, it can withstand a large enough pressure in the radial direction when it is docked, but the axial pressure resistance impact on the butt joint is very small, causing the joint to fall off, resulting in Plastic pipe joint failure
