Self-compensating direct quick-connection pipeline

Abstract

A self-compensating direct quick-connection pipeline comprises a left head 1, a pipeline 2, a right head 3 and a rubber sealing ring 4, is used for the contra-aperture quick connection of pipelines, and solves the defects that the prior pipe connection technique has high cost and poor practicability, wherein the left head 1 is inserted into and spirally buckled with the inner cavity of the right head 3, the rubber sealing ring 4 is compressed and sealed therein. The pipe fittings and valves of the self-compensating direct quick-connection pipeline are resistant to high pressure, medium pressure and low pressure, do not pull screw thread, are not welded, are not in flange mode, channeling mode and electric heating melting mode, are not additionally added with a compensator, are capable of realizing direct contra-aperture quick connection of the pipelines in severe environment conditions, such as lofty mountains and steep hills, deserts, water of rivers, lakes and seas, narrow space, windy, rainy, high-temperature and chill weather, combustible and explosive places, provide self-compensating lockable rigid-flexible omnibearing safety sealing, save labor and time, and have low cost, high efficiency, energy conservation and environment protection. The invention provides the self-compensating direct quick-connection pipeline for conveying fluids.

Description

technical field [0001] The invention relates to a self-compensating direct quick-connect pipeline for conveying fluid, which belongs to the field of pipeline engineering. Background technique [0002] Various large-diameter pipelines used to transport high-pressure, medium-pressure, and low-pressure fluids in pipeline engineering construction in various countries in the world mainly include straight seam welded steel pipes, stainless steel pipes, hot-rolled, cold-drawn seamless steel pipes, and spiral seam submerged arc welded steel pipes. , cast iron pipes, cast steel pipes, steel-plastic composite pipes, hard plastic pipes, high-pressure glass steel pipes and elbows, different diameters, four-way, three-way, variable-angle pipe fittings, and pipe valves for controlling fluid flow in pipelines mainly include gate valves , Check valves, ball valves, butterfly valves, safety valves, globe valves, filters, etc. In order to prevent the deformation of steel pipes due to thermal ...

AI Technical Summary

Problems solved by technology

[0010] Nowadays, the latest technology in large-diameter pipe joint technology at home and abroad, such as the invention patent of Wang Jianan's senior engineer "self-compensating fastening type large-diameter quick joint, patent application number 2008100688853", has its outstanding advantages compared with the original traditional pipe joint technology. Advantages, but in terms of pipeline counterpart connection technology, first put the rubber sealing ring on the counterpart pipeline - use the left and right sleeves to compress and seal the rubber sealing ring on it - install the toothed claws that can lock the pipeline - push The plate is placed on the end face of the claw - fastened with high-strength bolts and anti-rotation nuts, there are five shortcomings in the process
