Description

Inflating device for pre-inflating protective gas of pressure container Technical Field The utility model relates to the technical field of inflation, in particular to an inflation device for pre-inflating protective gas of a pressure container. Background In the welding process of the pressure container, in order to prevent internal oxidation caused by high temperature during welding of products, nitrogen is required to be filled into the container to discharge air before welding. Manual and manual nitrogen charging generally causes partial products to be not charged with nitrogen, so that the quality of the products is unstable, the internal volumes of different products are different, the required charging time is different, the manual operation is difficult to accurately adjust the charging time, the nitrogen charging effect is affected, and when the manual charging is performed, the problem that the charging time is overlong often occurs due to inconvenient time control, so that the waste of resources such as nitrogen is caused. Disclosure of utility model The utility model mainly provides an inflation device for pre-inflating protective gas of a pressure container, which is used for accurately controlling nitrogen inflation time, ensuring accurate nitrogen inflation quantity and improving nitrogen inflation effect. In order to achieve the aim, the air charging device for pre-charging protective gas of the pressure vessel adopts the following technical scheme that the air charging device comprises a large screen frame, one end of the large screen frame is fixedly connected with a fixing piece, the surface of the fixing piece is fixedly connected with a small screen frame, the surface of the large screen frame is fixedly provided with a power distribution cabinet close to the top, the surface of the power distribution cabinet is fixedly provided with a time controller, the top of the small screen frame is fixedly provided with a base, the top of the base is fixedly provided with a U-shaped plate, the inside of the U-shaped plate is provided with a gas switch, the inside of the U-shaped plate is fixedly provided with a connecting plate close to one end, the surface of the connecting plate is fixedly provided with an air charging head, and the surface of the fixing piece is fixedly provided with a gas flow device. Preferably, the bottom of the air charging head is fixed and communicated with an air outlet hose, and the other end of the air outlet hose is fixed and communicated with the air switch, so that the air switch can control the air outlet hose to give off air.
