Chemical transmission pipeline protection device

Abstract

The invention relates to the technical field of pipeline transportation equipment, and discloses a chemical transmission pipeline protection device. The chemical transmission pipeline protection device comprises a first pipe body, a second pipe body and a third pipe body; a middle pipe is arranged between the first pipe body and the second pipe body, and threaded pipes are fixedly communicated with the two ends of the middle pipe correspondingly; the other ends of the two threaded pipes are connected with one end of the first pipe body and one end of the second pipe body in a threaded and sleeved mode correspondingly; the outer surface of the first pipe body and the outer surface of the second pipe body are fixedly provided with fixing plates correspondingly in a sleeved mode; and the topand the bottom of one fixing plate are movably connected with locking bolts correspondingly in a sleeved mode. According to the chemical transmission pipeline protection device provided by the invention, through cooperative use of the middle pipe and the two threaded pipes, the first pipe body and the second pipe body can be connected together conveniently, overhauling by workers is facilitated, meanwhile, the connection tightness is improved, and through cooperative use of the fixing plates, the locking bolts and a locking nut, the connection stability between the middle pipe and the first pipe body and the second pipe body can be improved.

Description

technical field [0001] The invention relates to the technical field of pipeline transportation equipment, in particular to a chemical transmission pipeline protection device. Background technique [0002] Pipeline transportation is a long-distance transportation method of transporting liquid and gas materials using pipelines as a means of transportation. It is a transportation method that specifically transports petroleum, coal and chemical products from the production site to the market. It is the backbone of the unified transportation network. As a special component, pipeline transportation not only has large transportation volume, continuous, rapid, economical, safe, reliable, stable, low investment, small land occupation and low cost, but also can realize automatic control and is widely used in chemical production and transportation. [0003] The current chemical transmission pipelines are exposed to the outdoor environment. Because the pipeline connection is relatively ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a chemical transmission pipeline protection device, which has the advantages of improving the service life of the transportation pipeline and high overall stability of the pipeline, and solves the problem that the pipeline connection is relatively weak, the control valve body is relatively fragile, and is easily damaged. Changes in external environmental factors affect its service life. Most of the transmission pipes are simply fixed on the ground with fixing frames, which can easily lead to pipe deviation. It needs to be fixed for pipes of different calibers, and the transportation cost is high.
