A ferrule-type connection flared plastic pipe fitting

Abstract

The invention relates to the technical field of pipe fittings, in particular to a ferrule-type connection flaring plastic pipe fitting, including a pipe fitting, the inner cavity of the pipe fitting is provided with a connected pipe hole, the pipe fitting includes a thin-mouth joint and a flare joint, and the pipe fitting is threaded near the outer wall of the middle part. There is a first nut, the first nut includes a joint sleeve and a flared sleeve, the inner wall of the joint sleeve is threadedly connected with the outer wall of the narrow-mouthed joint, the flared sleeve is threadedly connected with the outer wall of the flared joint, and the outer wall of the narrow-mouthed joint is threadedly connected with a fixed block, the fixed block A limit rod is arranged between the joint sleeve and the end of the limit rod is fixedly connected with a buffer block, the end of the buffer block is provided with a buffer spring, the outer wall of the flared joint is threaded with a protective sleeve, and the outer wall of the protective sleeve is threaded with a second nut. The outer wall of the protective sleeve is threadedly connected to the inner wall of the flaring sleeve, and the inner cavity of the protective sleeve is provided with a sound-proof cavity, and the inner cavity of the sound-proof cavity is provided with sound-proof cotton. Stable and soundproof.

Description

technical field [0001] The invention relates to the technical field of pipe fittings, in particular to a ferrule-type connecting flared plastic pipe fitting. Background technique [0002] Pipe joints are parts that connect pipelines or install pipelines on hydraulic components in hydraulic systems. This is a general term for connectors that can be assembled and disassembled in fluid passages, mainly including: welded, ferrule and flared Applicable media for flared and flared pipe joints: oil, water, gas and other non-corrosive or corrosive medium pipe joints (the representative manufacturer is Shanghai Tongyang Pipe Fittings Co., Ltd.), and the specification requirements for matching steel pipes are relatively flexible After being welded with the pipeline, it has the characteristics of firm connection and good sealing performance, so it is widely used in oil refining, chemical industry, light industry, textile, national defense, metallurgy, aviation, shipbuilding and other s...
