Compression locking splicing type fluid conveying pipeline connecting device

Abstract

The invention discloses a compression locking splicing type fluid conveying pipeline connecting device. The compression locking splicing type fluid conveying pipeline connecting device comprises a compression cover, a pipe body, a rubber sealing ring and a locking clamp ring. A connected pipe is inserted in a limit step in the pipe body from the connected end of the pipe body, the rubber sealing ring is mounted in a sealing ring groove in the inner cavity of the pipe body, the locking clamp ring is arranged on a support platform of the inner cavity of the pipe body, a compression cover sleeves the connected pipe, and the compression cover is manually locked with the pipe body through threads. The compression locking splicing type fluid conveying pipeline connecting device has advantages of simple structure, fast mounting, high safety and reliability, high pressure bearing ability, low cost, broad application range and the like.

Description

technical field [0001] The invention belongs to the field of connecting pipe fittings for smaller pipe diameters and adopts a connection mode of compression locking and plugging to connect fluid delivery pipelines, and in particular relates to a connection device for compression locking and plugging fluid delivery pipelines. Background technique [0002] Fluid conveying pipeline connecting pipe fittings are an indispensable combination of connecting elements for the installation of fluid conveying pipeline systems. According to the material classification of connecting pipe fittings, they can be divided into plastic pipe fittings, galvanized malleable steel pipe fittings, stainless steel pipe fittings, copper pipe fittings and aluminum pipe fittings, etc. Among them, plastic pipe fittings are easy to age, shrink and deform, have limited bearing pressure and safety performance, and cannot carry high-temperature fluids; galvanized pipe fittings, stainless steel pipe fittings, a...

[0002] Fluid conveying pipeline connecting pipe fittings are an indispensable combination of connecting elements for the installation of fluid conveying pipeline systems. According to the material classification of connecting pipe fittings, they can be divided into plastic pipe fittings, galvanized malleable steel pipe fittings, stainless steel pipe fittings, copper pipe fittings and aluminum pipe fittings, etc. Among them, plastic pipe fittings are easy to age, shrink and deform, have limited bearing pressure and safety performance, and cannot carry high-temperature fluids; galvanized pipe fittings, stainless steel pipe fittings, and copper pipe fittings require special tools for processing and installation, complicated operation, high transportation costs, and impurities in the fluid It is easy to block the pipe body and reduce the flow rate; aluminum pipe fittings have the advantages of light weight and low transportation cost, but the existing aluminum pipe fittings have low pressure bearing performance, many components, complex structure, cumbersome installation and not easy to operate
