Liquid line transportation security system

Abstract

The invention provides a liquid line transportation security system comprising a liquid inlet pipe, an air outlet pipe, a drain pipe, a sealing ring, a rotary cap, a riving ball arm, a piston and bolts; the air outlet pipe is installed between the liquid inlet pipe and the drain pipe with the bolts, and the top of the air outlet pipe upward protrudes from an air header aslant; the top of the air header extends out of an inclined thin pipe and a horizontal thick pipe toward the inner cavity of the air header; the rotary cap is installed on the horizontal thick pipe through threads, one end of the driving ball arm is sheathed on the rotary cap, and the other end is connected to a floating ball; the piston is installed in the inclined thin pipe; gas in the air header increases, the floating ball moves down to drive the rotary cap to rotate and move toward the horizontal thick pipe; glycerol in the inclined thin pipe and the horizontal thick pipe is compressed to press the piston to move up and be exposed out of the air header and an external air vent, and the gas in the air header leaks outside; as the liquid level in the air header rises, the floating ball moves up to drive the rotary cap to move far away from the horizontal thick pipe, and the piston moves down to plug up the air vent again; the above actions are continuously circulated to discharge the gas in the line outside.

Description

technical field [0001] The invention relates to a pipeline auxiliary facility, in particular to a liquid pipeline transportation safety guarantee system. Background technique [0002] Pipeline transportation is a long-distance transportation method of transporting liquid or gas materials using pipelines as a means of transportation. It is a transportation method that specifically transports oil, natural gas, water, and other chemicals from the production site to the market. A special component of trunk transport. Pipeline transportation has the advantages of large transportation volume, continuous, rapid, economical, safe, reliable, stable, less investment, less land occupation, and low cost, and can realize automatic control. [0003] In liquid pipeline transportation, because the bubbles in the liquid will continue to mix and separate with the liquid during the movement, the bubbles are also constantly merging and separating, and at the same time, collisions between the b...

AI Technical Summary

Problems solved by technology

Because the mixing and separation of air bubbles and liquids under different pressure and temperature conditions is complex and different, people cannot completely separate liquids and gases. However, air bubbles generated during pipeline transportation can easily lead to pipeline explosion accidents, which will seriously threaten With social and economic development and the safety of people's lives and properties, it is one of the important issues to be solved in the process of pipeline transportation.
