Abstract

The invention discloses an explosion-protection rapid purging device for natural gas systems, which comprises a shell, a gas pipe and an gas-guide pipe both arranged outside the shell and respectively provided with a gas ball valve and a natural gas ball valve, a fire-extinguishing gas pipe connected with the other end of the gas ball valve, and a natural gas pipeline connected with the other endof the natural gas ball valve. The invention is characterized in that a partition is arranged inside the shell, and a gas-guide moving interface mechanism and a gas-guiding static interface mechanismtogether with linked ball valve control mechanisms thereof are arranged at two sides of the partition. The invention has the advantages of reasonable design, good effect, and strong function of automatic rapid purging; and is particularly incorporated in the PLC automatic control system together with the rapid cut-off valve, thereby realizing the rapid purging with capability of automatic safety control of natural gas.

Description

Technical field [0001] The invention relates to the technical field of gas use safety, in particular to a safety explosion-proof device for rapidly purging nitrogen or steam on gas equipment and facilities when gas equipment and facilities have low pressure or regional gas exceeds the standard before automatically cutting off gas. Background technique [0002] Industrial gas is not only highly toxic, but also has many impurities and strong corrosiveness. Due to the limitation of recovery process conditions, the pressure fluctuates greatly, which brings safety hazards to the use of gas. For example, impurity clogs the pipeline, which leads to a decrease in the pressure of the baking burner, which is prone to burner fire extinguishing, leakage and personnel poisoning accidents. Corrosion damages equipment, gas leakage occurs, and personnel poisoning accidents occur. Fluctuating low-pressure tempering, causing pipeline explosions and injury accidents. Therefore, with the wide...
