The utility model discloses a gaseous zero release inflation kit of sulfur hexafluoride, include the gas -charging connection of being connected with the sulfur hexafluoride air chamber, lead to the air through tube intercommunication between gas -charging connection and the air supply, the trachea switch -on of gas -charging connection one side has gas recovery device. Adopt according to the technical solution of the integrated ceiling board, after aerifing the completion, remaining sulfur hexafluoride is gaseous in the gas recovery device collection trachea that logical air through tube connects, under the prerequisite that has this kind of structure, even it is closed with the trachea of gas -charging connection that the air chamber check valve of equipment air chamber kneck does not in time return the normal position, the condition of gas leakage appears lasting in gas -charging connection department, the sulfur hexafluoride gas that gas recovery device also can be effectively reveals out gas -charging connection department is retrieved effectively, prevent that gas from spreading to the external world, cause the dangerous situation of personnel or equipment.
