Abstract
A control device of purging a gas pipeline is characterized in that the gas pipeline is connected with a nitrogen pipeline through two valves, and an emptying valve is arranged between the two valves. A distance between the two valves is not more than 300mm, and the emptying valve is arranged on the just middle between the two valves. The control device has advantages of simple structure, easy operation, safe and reliable use, and wide application of all gas fields.
Description
Technical field
The safety that the utility model is mainly used in combustion gas such as coke-stove gas, blast furnace gas, coal gas of converter, producer gas, coal-seam gas, rock gas, hydrogen purges operation, is specifically related to a kind of purge gas channel control gear.
Background technique
Gas ductworks such as coke-stove gas, blast furnace gas, coal gas of converter, producer gas, coal-seam gas, rock gas, hydrogen need purge with nitrogen when stopping transport maintenance.Existing purging control gear adopts gas pipeline to be connected with nitrogen pipeline by cut-off valve.Be in operation, nitrogen and combustion gas often take place scurry phenomenon mutually, influence ordinary production.
