Thick-wall clamping and pressing type pipe fitting

Abstract

The invention belongs to the technical field of clamping and pressing type pipe fittings, in particular to a thick-wall clamping and pressing type pipe fitting. The thick-wall clamping and pressing type pipe fitting comprises a thick-wall pipe fitting body arranged between two thick-wall steel pipe bodies and used for being connected with the thick-wall steel pipe bodies, and a sealing ring used for sealing, a positioning check ring and a gear ring are installed between the thick-wall pipe fitting body and the thick-wall steel pipe bodies; the thick-wall pipe fitting body comprises a connecting section located in the middle, a first flaring section and a second flaring section, wherein the first flaring section and the second flaring section expand and extend towards the two sides; a thick-wall metal pipe design is adopted, a special tool is used for crimping to deform the pipe fitting, so that the pipe fitting and a steel pipe are connected instantaneously, a crimping tool crimps a socket section of the pipe fitting, the socket section is provided with the sealing ring and the high-strength gear ring, and the sealing ring and the high-strength gear ring are compressed at the sametime to force the sealing ring in a socket section groove to cling to the steel pipe to achieve sealing and water-stopping operation; and the high-strength gear ring shrinks to firmly fasten the steelpipe, so that a good tensile effect is achieved. Due to the adoption of the thick-wall design, and good pressure-bearing performance and impact resistance are achieved.

Description

technical field [0001] The invention belongs to the technical field of compression-type pipe fittings, in particular to thick-wall compression-type pipe fittings. Background technique [0002] A pipeline is a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump and boiler, the high pressure from the pipeline It can also be transported by the pressure or gravity of the fluid itself. The pipeline is widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various In industrial installations, thick-wall compression fittings are one of the compression-type piping systems, mainly used in water supply and drainage, fire protection systems, gas, compressed air and other liquid and gas medium fluid transportation. [0003] At present, there...
